PART I


Item 1.	*Business*

Overview

Immersion Corporation was founded in 1993, and we consummated our initial public offering on November 12, 1999. Our common stock trades on the Nasdaq Stock Market under the symbol IMMR. Immersion Corporation is a leading provider of haptic technologies that allow people to use their sense of touch more fully when operating a wide variety of digital devices. To achieve this heightened interactivity, we develop and manufacture or license a wide range of hardware and software technologies and products. While we believe that our technologies are broadly applicable, we are currently focusing our marketing and business development activities on the following target application areas: automotive, consumer, entertainment, industrial, medical simulation, mobile communications, and three-dimensional design and simulation. We manage these application areas under two operating and reportable segments: 1) Immersion Computing, Entertainment, and Industrial and 2) Immersion Medical.

In markets where our touch technologies are a small piece of a larger system, such as mobile phones and controls for automotive interfaces, we license our technologies or software products to manufacturers who integrate them into their products and sell the end product(s) under their own brand names. In some markets, we have brand visibility on consumer packaging, end-user documentation, and in software applications. In other markets, such as medical simulation, touchscreen input devices, and three-dimensional computer-aided design, we manufacture and sell products under our own Immersion brand name, through direct sales, distributors, and value-added resellers. In all market areas, we also engage in development projects for third parties and government agencies from time to time.

Our objective is to drive adoption of our touch technologies across markets and applications to improve the user experience with digital devices and systems. We and our wholly owned subsidiaries hold more than 500 issued or pending patents in the U.S. and other countries, covering various aspects of hardware and software technologies.

Haptics and Its Benefits

The science of haptics refers to tactile and kinesthetic information that supplies a tangible representation of the environment to the human sensory system. The term “force feedback” has often been used to mean haptics in general, though haptics is actually comprised of two types of sensing and two types of technologies. Tactile sensing refers to an awareness through stimulation of the skin, which can be accessed through vibro-tactile technologies.

Kinesthetic sensing refers to an awareness through the position of body parts and their movement, which can be accessed using force feedback technologies. Without our perception of haptic information, it would be hard to believe that something is tangible. Unlike sight and hearing, which are mainly input systems, touch is bi-directional, allowing us to both feel (take in information) and manipulate (have an effect on something).

All human senses are complementary, contributing to our perception of the environment. Without one of them, our perception would change — and without touch, any motor action, such as typing, peeling an orange, or opening a door would be extremely difficult. A person’s sense of touch and the haptic information it interprets is a critical part of our interactions with the world.

In the world of computers and digital devices and controls, haptic feedback is often lost. To replace the lost sensation of touch, input/output devices can create the physical forces, known as haptic feedback, force feedback, touch feedback, or tactile feedback. These forces are exerted by actuators, usually motors, which are built into consumer devices such as joysticks, steering wheels, gamepads, and mobile phones. Actuators can also be designed into more sophisticated devices used in automotive, industrial, medical, or retail kiosk and point-of-sale systems, such as digital switches, rotary controls, and touchscreens. Our programmable haptic technologies embedded in touch-enabled devices can give users the physical sensations of interacting with rough textures, smooth surfaces, viscous liquids, compliant springs, solid barriers, deep or shallow detents, jarring vibrations, heavy masses, and rumbling engines.

As a user operates a touch-enabled device, such as a joystick, motors within the device apply computer-modulated forces that resist, assist, and enhance the manipulations. These forces are generated based on software algorithms and mathematical models built to produce appropriate sensations. For example, when simulating the feel of interacting with a solid wall or barrier, a computer program can signal motors within a force feedback joystick to apply forces that emulate the impenetrability of the wall. The harder the user pushes, the harder the motors push back. When simulating the placement of cardiac pacing leads, a computer program can signal actuators to apply forces that would be encountered when navigating coronary pacing leads through a beating heart. These forces can be synchronized with appropriate simulations of an electrocardiogram, blood pressure, heart rate, and fluoroscopy displays. When simulating the feel of pressing a button, a computer program can signal actuators attached to a touchscreen to apply forces that emulate the button’s particular press and release characteristics. Even though the user touches a screen that is flat, our technology delivers the perception that the button is pushed inward.

For mobile phones, our software can control the motor used in substantially all phone models, thereby enhancing the output — from a simple on-off buzz to a rich palette of tactile communications. Our programmable haptic system can be used, for example, to advise users of the identity of an incoming caller, supply vibrations signifying an emotion in a text message, provide a tactile alert, and aid in general navigation and operation. Ringtones can also be haptically enhanced, allowing users to feel the beat of a particular song. Mobile games are made more engaging and enjoyable by adding vibro-tactile effects to particular events such as explosions, car crashes, and bowling strikes.

The mathematical models that control motors may be simple modulating forces based on a function of time. These forces can produce jolts and vibrations for example. More complex forces can emulate surfaces, textures, springs, and damping. All forces can be synchronized with audio, video, or application program logic. For example, a series of individual simulated forces can be combined to give the seamless feel of a complex interaction, like driving a sports car, which might include the centrifugal forces in the steering wheel, the vibration of the road surface, the revving of the engine, and the bass beat of a song.

We believe the programmability of our haptic products is a key differentiator over purely electro-mechanical systems and can drive the further adoption of digital devices. A programmable device can supply a tactile response appropriate to the context of operation for systems and devices of many types. These tactile cues can help users operate more intuitively or realize a more enjoyable or natural experience. Used in combination with sight and sound cues, touch feedback adds a compelling, engaging, multimodal aspect to the user interface. Our haptic products and technologies can also add a tactile quality to interactions that have been devoid of tactile confirmation, such as when using a touchpad or touchscreen. The confirmation and navigational cues obtained by programmable haptics can aid in performance and accuracy and increase user satisfaction. The addition of programmable haptics

can help in the conversion from purely mechanical rotary controls to digital devices or from a mechanical keyboard, switch, or button interface to an electronic touchscreen.

Programmability also supplies more flexibility in terms of the types of responses that are possible (such as nonlinear or dynamic qualities), in upgradeability, in consistent performance that will not degrade over time, and in the potential for personalized settings.

Multiple mechanical controls can be consolidated into one versatile programmable control, which can save space and improve ergonomics. Conversely, one programmable control device can be implemented as many different types of controls with context-appropriate touch feedback, which can simplify inventory.

Industry Background

Haptic systems were first used in applications like military flight simulators. In the 1960s, combat pilots honed their flight skills in training simulators that replicated the feel of flying actual planes. Motors and actuators pushed, pulled, and shook the flight yoke, throttle, rudder pedals, and cockpit shell, reproducing many of the tactile and kinesthetic cues of real flight. Though advanced for their time, these systems were limited by the then available technology and were therefore relatively crude and low fidelity by today’s standards. They also cost at least hundreds of thousands, if not millions of dollars, and therefore were not within the grasp of consumers or even most businesses.

By the late 1970s and early 1980s, computing power reached the point where rich color graphics and high-quality audio were possible. Computers evolved from primitive command-prompt, text-based systems with monochrome displays to powerful systems capable of rendering colorful graphics and animations and of playing music and sound effects. These advancements spawned entirely new businesses in the late 1980s and early 1990s.

To the consumer, this multimedia revolution opened new possibilities. Flight simulation moved from a professional pilot-only activity to a PC-based hobby for millions of real and aspiring pilots. The graphics and sound these hobbyists experienced were far superior to what the combat pilots in the 1960s had in their expensive flight simulator systems.

The multimedia revolution also made the medical simulation business possible. By the 1990s, high-end workstations enabled renderings of the human anatomy to be displayed with never before possible realism. Companies were founded to harness this new technology and turn it into safer and more effective teaching aides for medical personnel.

However, the multimedia revolution also highlighted a shortcoming in simulation products. Even though medical graphics and animations looked incredibly realistic, they could not possibly convey what it actually feels like to break through a venal wall with a needle or cut through the tissue surrounding the gall bladder. In the case of flight simulation, graphics and sound could not possibly convey what it actually feels like to fight the flight yoke or flight stick out of a steep dive or through a sharply banked turn. Only hands-on experience provided this critical component of learning.

So by the mid 1990s, these new industrial and consumer multimedia products were in need of enhanced haptic technology that could provide the sensations similar to an actual hands-on experience. We were founded in 1993 to bring the critical sense of touch back into the user’s experience. By combining 1) the basic concepts used in the military flight simulators of the 1960s, 2) state-of-the-art advancements in robotic controls, 3) advancements in the understanding of how the human sense of touch works, and 4) advancements in computing power, we were able to significantly reduce the cost and size of haptic solutions while increasing the quality of the simulated forces. Some of our early technology was used in the world’s first consumer force feedback peripherals for computer video games, such as flight sticks and steering wheels. These products not only looked and sounded more realistic, they allowed users to feel haptic effects that simulated, for example, textures, bouncing and hitting a ball, and vibrations from gun fire. In addition, with our technology, sophisticated medical simulators offered medical professionals the ability to practice and enhance their surgical and other procedural skills in a way not previously possible.

Continued advancements in size, power, and cost reductions have pushed the adoption of haptics technology even further into those industries, as well as into new ones. Our TouchSense^® technology is now incorporated into

computer and console gaming systems, and in products such as gamepads, joysticks, and steering wheels for Sony’s PlayStation and PlayStation 2, Microsoft’s Xbox and Xbox 360, Nintendo’s GameCube, and the PC and Apple Macintosh computer. Furthermore, more than 1,300 Immersion Medical simulators have been deployed at hospitals and medical schools throughout the United States and abroad, including Beth Israel Deaconess Medical Center, Mayo Clinic (Rochester, MN), Northwestern University, Rush University Medical Center, St. Mary’s Hospital (London), and Stanford University.

Over the past few years, the ever-increasing demands of connectivity, interactivity, and functionality have driven advancements in mobile phone capabilities. Improvements focused on processing power, data communications bandwidth, operating system sophistication, and memory, as well as user interface design, high-resolution color displays, stereo speakers, and motor and case design. As a result, our TouchSense software and technology used in the gaming market is now being deployed as VibeTonz^® software products for mobile phone handsets.

Although the first touchscreens were introduced in the early 1970s, their broad acceptance and proliferation didn’t occur until the mid to late 1990s. Since their introduction, advancements in computing power, operating systems, graphical user interfaces, and multimedia software, combined with gradual cost reductions, have today made the touchscreen the user interface device of choice for many applications. In 2005, we announced a TouchSense technology solution to enable enhanced tactile cues for providing a more intuitive, personal, and natural experience for the user. Instead of just feeling the passive touchscreen surface, users perceive that buttons press and release, just as physical buttons and switches do, creating a class of products we call active touchscreens.

Our haptic technologies are also now used by corporate industrial designers and by researchers from the National Aeronautics and Space Administration (NASA), Stanford University, and the Massachusetts Institute of Technology (MIT). Automobiles manufactured by BMW, Mercedes-Benz, Rolls Royce, and Volkswagen use programmable haptic controls powered by Immersion technology. In addition, we offer 3D capture and interaction products to help game developers, mechanical designers, animators, and other professionals reduce production time and streamline the workflow process. Today, we believe that as computing power increases and pushes multimedia capabilities into new areas, even more opportunities will be created for our programmable haptic technologies.

Our Solutions

Our goal is to change the way people interact with digital devices by engaging their sense of touch. Core competencies include our understanding of how interactions should feel and our knowledge of how to use technology to achieve that feeling. Our strength in both of these areas has resulted in many novel applications.

We believe that our touch-enabled products and technologies give users a more complete, intuitive, enjoyable, and realistic experience. Our patented designs include software elements such as real-time software algorithms and authoring tools, and specialized hardware elements, such as motors, sensors, transmissions, and control electronics. Together, these software and hardware elements enable tactile sensations that are context-appropriate within the application.

We have developed haptic systems for many types of hardware input/output devices such as computer mice, joysticks, mobile phones, rotary devices, touchscreens, and flexible and rigid endoscopy devices for medical simulations.

We have developed many mechanisms to convey forces to the user’s hands or body. These include vibro-tactile actuators, direct drive or cable driven mechanisms, and other proprietary devices that supply textures and vibration, resistance, and damping forces to the user.

To develop our real-time electronic actuator controllers, we had to address challenges such as size, accuracy, resolution, frequency, latency requirements, power consumption, and cost. Our control solutions include both closed-loop and open-loop control schemes. In closed-loop control, the firmware reads inputs from the input/output devices, and then calculates and applies the output forces in real time based upon the input data. In open-loop control, a triggering event will activate the firmware to calculate and send the output signal to the actuator in real time.

We have developed many software solutions for various operating systems and computing platforms including mobile handset operating systems. Our inventions include many generations of authoring tools for creating, visualizing, modifying, archiving, and experiencing haptic feedback.

Licensed Solutions

In markets where our touch technology is a small piece of a larger system (such as mobile phones and controls for automotive interfaces), we license our technologies or software products to manufacturers who integrate them into their products sold under their own brand names.

We offer our expertise to our licensees to help them design and integrate touch effects into their products. This expertise includes turn-key engineering and integration services, authoring tools, application programming interfaces, and the development of hardware and software technologies that are compatible with industry standards.

Turn-key Engineering and Integration Services. We offer engineering assistance including technical and design assistance and integration services that allows our licensees to incorporate our touch-enabling products and technologies into their products at a reasonable cost and in a shortened time frame. This allows them to get to market quickly by using our years of haptic development expertise. We offer product development solutions including product software libraries, design, prototype creation, technology transfer, component sourcing, development/integration kits, sample source code, comprehensive documentation, and other engineering services. In addition, we ensure a quality end-user experience by offering testing and certification services to a number of licensees.

Authoring Tools. We license authoring tools that enable software developers to quickly design and incorporate custom touch feedback into their own applications. Authoring tools allow designers to create, modify, experience, and save or restore haptic effects for a haptic device. The tools are the equivalent of a computer-aided design application for haptics. Our authoring tools support vibro-tactile haptic devices (such as mobile phones and vibro-tactile gaming peripherals), as well as kinesthetic haptic devices (such as rotary devices, joysticks, and medical training systems). Various haptic effect parameters can be defined and modified and the result immediately experienced. Our authoring tools run on mainstream operating systems such as Microsoft Windows.

Application Programming Interfaces (“APIs”). Our APIs provide haptic-effect generation capability. This allows designers and programmers to focus on adding haptic effects to their applications instead of struggling with the mechanics of programming real-time algorithms and handling communications between computers and devices. Some of our haptic APIs are device independent (for example, they work with scroll wheels, rotary knobs, 2D joysticks, and other devices) to allow flexibility and reusability. Others are crafted to meet the needs of a particular customer or industry.

Compatible with Industry Standards. We have designed our hardware and software technologies for our licensees to be compatible with industry hardware and software standards. Our consumer technologies operate across multiple platforms and comply with such standards as Microsoft’s entertainment application programming interface DirectX and a standard communications interface, Universal Serial Bus (“USB”). Our APIs are supported on Windows and Macintosh platforms and are capable of being ported onto other operating systems such as for mobile phones, automobiles, and industrial controls. Software plug-ins and API extensions are available for several platforms so that programmers can add our touch technology into their applications. Most of our software technology has been designed to be platform independent. Our software supports many operating systems including Windows, Windows CE, BREW/REX (from QUALCOMM), Java (J2SE), VxWorks, and Linux, and many communication protocols including USB, CAN Bus, and serial.

Manufactured Product Solutions

We produce our products using both contracted and in-house manufacturing capabilities. In some markets, we manufacture and sell products under the Immersion brand name through a combination of direct sales, distributors, and value-added resellers. These products include:


	•	medical simulation systems used for training medical professionals in minimally invasive medical procedures including vascular access, endoscopy, hysteroscopy, laparoscopy, and endovascular;


	•	components used in our touchscreen solution;

	•	programmable rotary control modules for operating a wide range of devices;

	•	digitizers used to construct detailed 3D computer models and to perform accurate part inspections;

	•	a 3D interaction product line consisting of hand-centric hardware and software solutions for animating hand movements and allowing users to manipulate virtual objects with their hands; and

	•	electronics and force feedback devices for arcade games, university research, and other industrial applications.

Our Strategy

We intend to maintain and enhance our position as a leading provider of touch-enabling technology by employing the following strategies:

Pursue Royalty-based Licensing Model for High Volume Applications of Our Technologies. We believe that the most effective way to proliferate our touch-enabling technologies, where touch is a small part of a larger system, is to license and embed it in high volume applications. We have licensed our intellectual property to numerous manufacturers of joysticks, gamepads, and steering wheels, and to a manufacturer of video console gaming systems, all of which are targeted at consumers. In addition, our technologies have been licensed to automotive manufacturers and automotive parts suppliers for use in automotive controls. We have licensed our software products that create touch feedback effects in mobile handsets to manufacturers of mobile phones, wireless operators, and content developers. We intend to expand the number and scope of our licensing relationships in the future.

In general, our licenses permit manufacturers to produce only a particular category of product within a specified field of use. Our licensing model includes an up-front license fee and/or a per-unit royalty paid by the manufacturer that may be a fixed fee or a percentage of the selling price of the final touch-enabled product. In addition, our consumer-products’ licensees generally have branding obligations. The prominent display of our TouchSense or VibeTonz technology logo on retail packaging generates customer awareness for our technologies.

Pursue Product Sales in Lower-volume Applications through Multiple Channels. For lower-volume emerging applications of our technologies, such as medical simulation systems, active touchscreens, and three-dimensional and design products, our strategy is to manufacture and sell products through direct sales, distributors, and value-added resellers. The Immersion Computing, Entertainment, and Industrial segment sells products that consist primarily of digitizers, such as the MicroScribe^® line, specialized whole-hand sensing gloves and software, such as the CyberGlove^® II wireless glove, CyberGrasp^® system, and CyberForce^® armature that permit simulated interaction with three-dimensional environments, and TouchSense components and software for our touchscreen and rotary control solutions. Our Immersion Medical segment currently sells medical simulation devices that simulate intravenous catheterization, endovascular interventions, and laparoscopic, hysteroscopic, and endoscopic procedures.

Secure Licensees and Customers in New Markets for Touch-enabling Technology and Software Products. We believe that our touch-enabling technologies can be used in virtually all areas of computing and communication. We initially focused on computer gaming applications for personal computers and dedicated game consoles, an area in which key companies have accepted our technologies. We have broadened our focus in additional applications including automotive controls, industrial equipment controls, touchscreens, and mobile phones, and secured several new licensees in these areas. We intend to pursue additional applications for our technologies.

Facilitate Development of Touch-enabled Products. Our success depends on the development of touch-enabled products by our licensees and customers. To enable that development, we offer design packages that include sample hardware, software, firmware, and related documentation, and offer our technical expertise on a consulting basis. We will continue to devote significant resources to facilitate the development of touch-enabled products by our licensees and customers.

Expand Software Support for Our Touch-enabling Technologies. In addition to licensing our intellectual property or software products and supporting licensee product development efforts, we have focused on expanding

software support for our touch-enabling technologies. For example, we license authoring and programming tools to customers in support of vibro-tactile haptic devices (such as mobile phones, vibro-tactile gaming peripherals, and touchscreens) as well as kinesthetic haptic devices (such as rotary devices, joysticks, and steering wheels). Using our authoring tools, various haptic-effect parameters can be defined and modified, and the result can be immediately experienced on the target device.

Our APIs provide an extensive haptic-generation capability and allow designers and programmers to focus on enabling their target applications with haptic effects instead of struggling with the mechanics of programming real-time algorithms and handling communications between computers and devices. One focus of our marketing efforts is to promote the adoption of our touch-enabling technologies by software developers in certain markets. We have developed the VibeTonz Studio Software Development Kit (“SDK”) and TouchSense SDK that contain items such as programming or authoring tools, documentation, tutorials, and software files containing sample touch effects. Our software support staff also works closely with developers to assist them in developing compelling touch-enabled applications. We also worked closely with Microsoft on the Microsoft DirectX Software Development Kit, contributing to the API specification and offering our own authoring tools, documentation, tutorials, and sample program to supplement the DirectX SDK.

Expand Market Awareness. We promote adoption of our touch-enabling technologies by increasing market awareness as appropriate in our various market segments. We believe that it is important to increase awareness among potential customers and, in some markets, end users. As a part of many of our consumer-product license agreements, we require our licensees to use our trademarks and logos to create brand awareness among consumers. To generate awareness of our technologies and our licensees’ products, we participate in industry tradeshows, maintain ongoing contact with industry press, and provide product information on our Web site. To generate increased awareness and sales leads, we execute marketing campaigns specific to each market. These campaigns for a specific market may include public relations, direct mail, Internet marketing, advertising, tradeshows, and/or public speaking at industry events.

Develop and Protect Touch-enabling Technology. Our success depends in part on our ability to license and commercialize our intellectual property and to continue to expand our intellectual property portfolio. We devote substantial resources to research and development and are engaged in projects focused on expanding the scope and application of our technologies with particular emphasis on mobile-phone, tactile-touchscreen, and medical-simulation product offerings. We have also secured technology by acquisition and may do so again in the future. We intend to continue to invest in technology development and potential acquisitions and to protect our intellectual property rights across all of our businesses.

Immersion Computing, Entertainment, and Industrial Segment

	•	We joined the Symbian Platinum Partner Program to help simplify and speed the integration of the VibeTonz System on mobile phones that use the Symbian OS.

Automotive

In recent years there has been a proliferation of automotive sub-systems, which are directly accessed by drivers and passengers. These include telephone, navigation, climate controls, personal comfort, and audio, video, and satellite radio entertainment systems. As a result, there has been an increase in the number of physical control devices in the automotive center console, creating space and driver distraction problems.

We have developed TouchSense technology for both rotary controls and touchscreens appropriate for use in automobiles. TouchSense rotary technology can consolidate the control of multiple systems into a single module

that provides the appropriate feel for each function. This allows the driver convenient access to many systems and supplies context-sensitive cues for operation. TouchSense touchscreen technology provides tactile feedback for an otherwise unresponsive surface. Programmable haptic touchscreen, touch surface, and rotary controls of many types can be used to provide a space-saving, aesthetic look and a confirming response for the driver that can help reduce glance time.

We are also conducting various funded development efforts and providing tools and evaluation licenses to several major automobile manufacturers and suppliers who have expressed interest in touch-enabled automobile controls.

BMW was the first automobile manufacturer to license our TouchSense rotary technology for use in controls starting with its 2002 7 Series sedan model. BMW has also included our technology in the Rolls Royce and in some models of its 5 Series and 6 Series starting in 2003. Siemens VDO Automotive has licensed our technology for use in the high-end Volkswagen Phaeton sedan. ALPS Electric, also a licensee, has produced a haptic rotary control that has been included in the new Mercedes-Benz S class sedan currently being sold.

In 2005, Methode Electronics, Inc., a global designer and manufacturer of electronic component and subsystem devices, licensed a broad range of TouchSense technology for use in products sold to automotive OEMs and their suppliers. Europe’s largest automaker, Volkswagen, also licensed TouchSense technology for use in its vehicles.

For the years ended December 31, 2005, 2004, and 2003, 8%, 8%, and 6%, respectively, of our total revenues were Automotive revenues.

3D and Mechanical CAD Design

Our three-dimensional and mechanical computer-aided design products allow users to create three-dimensional computer models directly from physical objects and also to precisely measure manufactured parts. These products include the MicroScribe product line, which contains sensor and microprocessor technologies that allow users to measure or digitize physical objects simply by tracing their contours with a stylus. Third-party software records the three-dimensional measurements or geometry of the object and reproduces it on the screen as a three-dimensional computer model. In another application, third-party software compares the desired dimensions to three-dimensional measurements of an actual part to determine if it is within tolerance. Taken together, these capabilities support high-accuracy parts inspection, reverse engineering, game development, animation, and filmmaking applications.

We manufacture and sell the CyberGlove system, a fully instrumented glove that accurately measures the movement of a user’s hand and, used in conjunction with our software, maps the movement to a graphical hand on the computer screen. In 2005, we released a new wireless version of the CyberGlove system. Users can “reach in and manipulate” digital objects similar to physical objects. The CyberTouch^tm system is a CyberGlove product with a vibro-tactile feedback option that provides users with appropriate feedback when individual fingers contact digital objects. The CyberGrasp system is an option for the CyberGlove product that adds kinesthetic force feedback to the fingertips. With a CyberGrasp system, users can actually feel the shape and malleability of 3D graphical objects being held in the fingertips and manipulated on the screen. The CyberForce product is an enhanced, grounded, force feedback product. Incorporating our TouchSense technologies, a CyberForce system allows users to experience sensations similar to the CyberGrasp, but with whole-arm, whole-hand, as well as fingertip interactions.

Our software products for our whole-hand interfaces include VirtualHand^® SDK, VirtualHand for MotionBuilder, and VirtualHand for V5. VirtualHand SDK is a software toolkit that helps users integrate our whole-hand glove-based interface products into specific applications. VirtualHand for MotionBuilder lets users acquire, edit, and blend motion animation in Alias’ MotionBuilder real-time capture software. VirtualHand for V5 leverages our relationship with Dassault Systemes by bringing our glove-based products directly into the CATIA V5 and ENOVIA V5 environments, allowing for real-time interaction with digital prototypes for the evaluation of ergonomics, assembly, and maintainability of products. Users may develop multiple digital-design iterations to replace the need for physical prototypes, thereby reducing costs and time to market.

In addition to these 3D products, we manufacture and sell specialized products such as computer peripherals that are not touch-enabled, but incorporate related advanced computer peripheral technologies. These specialized peripherals include the SoftMouse^®, a high performance, nonhaptic mouse optimized for use in geographic information systems and mapmaking.

For the years ended December 31, 2005, 2004, and 2003, 17%, 19%, and 25%, respectively, of our total revenues were 3D and mechanical CAD design revenues.

Sales and Distribution

Sales of these products generally do not experience seasonal fluctuations, except for royalties from gaming peripherals, which tend to be significantly higher during the year-end holiday shopping season. However, there may be variations in the timing of revenue recognition from development contracts depending on numerous factors including contract milestones and operations scheduling. Our products incorporate readily available commercial components. There are no unusual working capital requirements in the Computing, Entertainment, and Industrial segment. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” as well as the notes to the consolidated financial statements for revenue information for the past three years.

In the PC and video console gaming, mobility, and automotive markets, we establish licensing relationships through our business development efforts.

In mobility, sales relationships must be established with operators, handset manufacturers, and content developers worldwide. We have signed license agreements with mobile handset manufacturers for the incorporation of the VibeTonz System into certain mobile phone handsets. We have established relationships with CDMA platform developer QUALCOMM, Incorporated and with smartphone operating system developer Symbian, Ltd. Discussions are ongoing with other handset manufacturers, operators, and content developers in the United States, Europe, and Asia.

We employ a direct sales force in the United States, Europe, and Asia to license our VibeTonz software products. In gaming, our sales force is also augmented through co-marketing arrangements. As part of our strategy to increase our visibility and promote our touch-enabling technology, our consumer-products license agreements generally require our licensees to display the TouchSense or VibeTonz technology logo on their end products.

We sell our touchscreen products to OEMs and system integrators, such as 3M Touch Systems, Advanced Input Systems, and StacoSwitch, using a worldwide direct sales force. In addition, the technology is licensed to large customers in automotive and other markets.

In the automotive market, we use a worldwide direct sales force to work with vehicle manufacturers and component suppliers. We have also licensed our technology to Methode and ALPS Electric, leading automotive component suppliers, as part of our strategy to speed adoption of our TouchSense technologies across the automotive industry.

The MicroScribe product line, along with first- and third-party hardware accessories and companion software, is sold through an international network of over 75 resellers. In addition to direct sales, our 3D whole-hand interaction products are distributed, sold, and supported by a growing worldwide network of over 20 international and domestic resellers. We have marketing relationships or contracts with leading 3D CAD/CAM and interaction companies, including Dassault Systemes, a worldwide leader in product lifecycle management software.

Competition

With respect to touch-enabled consumer products, we are aware of several companies that claim to possess touch feedback technology applicable to the consumer market, but we do not consider these products to be significant competition. In addition, we are aware of several companies that currently market unlicensed touch feedback products in consumer markets. We are engaged in litigation with two of these companies, Sony Computer Entertainment, Inc. and Sony Computer Entertainment of America, Inc., regarding infringement of our patents.

Several companies also currently market touch feedback products that are competitive to ours in nonconsumer markets. These companies could also shift their focus to the consumer market. In addition, our licensees or other

companies may develop products that compete with products employing our touch-enabling technologies, but are based on alternative technologies, or develop technologies that are similar or superior to our technologies, duplicate our technologies, or design around our patents. Many of our licensees, including Microsoft, Logitech, Samsung, and others have greater financial and technical resources upon which to draw in attempting to develop computer peripheral or mobile phone technologies that do not make use of our touch-enabling technologies.

With respect to our MicroScribe product line, we believe the G2 model, aimed primarily at the design, animation, and reverse engineering markets, competes favorably with other digitizing technologies, such as laser scanning and sonic systems, and with other articulated arm models, which are all of higher accuracy and higher price than these markets generally require. The MicroScribe MX model, aimed at high-accuracy manufactured parts inspection and reverse engineering markets, competes favorably on price to other coordinated measurement machine (CMM) models manufactured by Faro Technologies and Romer CimCore which is a part of Hexagon AB. It also competes favorably with these competitors for many types of projects where accuracy measurement tolerances are greater than 0.004-inch.

SensAble Technologies currently sells high-end 3D sculpting and design products that employ haptics. We believe that SensAble’s products compete on some level with our 3D interaction products. Competitors to our CyberGlove data glove include Fifth Dimension Technologies, Phoenix Technologies, and Measurand.

For licensed applications, our competitive position is partially dependent on the competitive positions of our licensees that pay a per-unit royalty. Our licensees’ markets are highly competitive. We believe that the principal competitive factors in our licensees’ markets include price, performance, user-centric design, ease-of-use, quality, and timeliness of products, as well as the manufacturer’s responsiveness, capacity, technical abilities, established customer relationships, retail shelf space, advertising, promotional programs, and brand recognition. Touch-related benefits in some of these markets may be viewed simply as enhancements and compete with nontouch-enabled technologies.

Our failure to obtain or maintain adequate protection for our intellectual property rights for any reason could hurt our competitive position. There is no guarantee that patents will be issued from the patent applications that we have filed or may file. Our issued patents may be challenged, invalidated, or circumvented, and claims of our patents may not be of sufficient scope or strength, or issued in the proper geographic regions, to provide meaningful protection or any commercial advantage.

Immersion Medical

Products and Markets

We have developed numerous simulation technologies that can be used for medical training and testing. By enabling a medical simulator to more fully engage users’ sense of touch, our technologies can support realistic simulations that are effective in teaching medical students, doctors, and other health professionals what it feels like to perform a given procedure. The use of our simulators allows these professionals to perfect their practice in an environment that poses no risks to patients, where mistakes have no dire consequences, and where animal or cadaver use is minimized. We partner with leading medical technology companies, such as Medtronic Inc. and Terumo Cardiovascular Systems Corporation, to develop products that closely simulate not only the look, but also the feel, of performing actual medical procedures.

We have five medical simulation product lines: the CathSim^® AccuTouch^® System, which simulates vascular access procedures such as intravenous catheterization and phlebotomy; the Endoscopy AccuTouch System, which simulates endoscopy procedures, including bronchoscopy and lower and upper GI endoscopic procedures; the Endovascular AccuTouch System, which simulates endovascular interventions, including cardiac pacing, angiography, angioplasty, and carotid and coronary stent placement; the Laparoscopy AccuTouch System, consisting of simulation hardware that can be integrated with third-party software for laparoscopic surgical procedure simulation; and the Hysteroscopy AccuTouch System, which simulates hysteroscopy procedures. These systems are used for training and educational purposes to enable health professionals to feel simulated forces that they would experience during actual medical procedures, such as encountering an unexpected obstruction in an artery. The

systems provide a realistic training environment augmented by real-time graphics that include anatomic models developed from actual patient data and high-fidelity sound that includes simulated patient responses.

All our AccuTouch products, except for the laparoscopic system, are comprised of a hardware system, an interface device, and software modules that include several cases of increasing difficulty, allowing users to develop their skills by experiencing a broad range of pathologies in differing anatomical conditions.

We design each product line to maximize the number of procedures that can be simulated with minimal additional customer hardware investment. These systems then enable potential additional sales of software to the installed base of hardware systems. We believe the relatively low price of our software modules provides an opportunity for repeat sales. We currently have over 25 various software modules available that replicate such medical procedures as intravenous catheterization, peripherally inserted central catheters (PICC), bronchoscopy, colonoscopy, cardiac pacing, carotid and coronary angioplasty, and hysteroscopy.

For the years ended December 31, 2005, 2004, and 2003, 11%, 17%, and 18%, respectively, of our total revenues were from Medtronic.

Sales and Distribution

Sales of these products may experience seasonal fluctuations related to teaching hospitals’ summer residency programs. In addition, there may be variations in timing of revenue recognition from the sale of systems with upgrade rights and from development contracts. The latter may depend on numerous factors including contract milestones and timing of work performed against the contract. Most raw materials used in the manufacturing of our products are readily available commercial components. There are no unusual working capital requirements in the Medical segment. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” as well as the notes to the consolidated financial statements for revenue information for the past three years.

With respect to medical simulation products, we employ a direct sales force in the U.S. that markets simulation systems to hospitals, colleges and universities, nursing schools, medical schools, emergency medical technician training programs, the military, medical device companies, and other organizations involved in procedural medicine. We have eight regional medical sales representatives in the United States. We also have one independent sales representative in Europe and 28 resellers outside the U.S.

For the years ended December 31, 2005, 2004, and 2003, 40%, 42%, and 47%, respectively, of our total revenues were Medical revenues.

Competition

There are several companies that currently sell simulation products to medical customers. Some simulators target the same minimally invasive procedures as do ours, while others sell mannequin-based systems for emergency response training. All simulators compete at some level for the same funding in medical institutions. Competitors include Simbionix USA Corporation, Mentice Corporation, Laerdal Medical AS, Medical Education Technologies, Inc., and Medical Simulation Corporation. The principal competitive factors are the type of medical procedure being simulated, technological sophistication, and price. We believe we compete favorably on all three.

Research and Development

Our success depends on our ability to invent, improve, and reduce the costs of our technologies in a timely manner, produce our products cost effectively, and interact with our licensees who are integrating our technologies and licensed software into theirs.

Immersion Engineering. We have assembled a team of highly skilled engineers and scientists who possess experience in the disciplines required for touch-enabling technology development, including mechanical engineering, electrical engineering, firmware, control system, computer science, and haptic content design. For medical simulations, we have assembled a unique team of experts who are skilled at modeling the anatomy and physiology of various medical cases, creating graphical renderings, designing haptic feedback, and devising advanced control algorithms to simulate realistic navigation for medical procedures, such as through the body’s blood vessels.

Licensee Interaction. In order to increase the successful design and adoption of our technology or software products in a licensee’s product, we make efforts to ensure clear communication between us and our customers. Typically, collaborative development efforts are structured using a four-phase approach including Product Definition, Concept Development, Detail Design, and Production Design phases. At the conclusion of each phase, a review meeting is held with team members from both companies to examine what was discovered and the conclusions that were reached during that portion of the project. These reviews provide an excellent opportunity to reassess the project direction and product viability prior to entering subsequent phases. The continuation of our development effort is contingent upon successful completion of prior phases. This method ensures that the customer’s financial risk is minimized and that project deliverables remain consistent with the goals established in the Product Definition phase.

The four-phase design process is typically used for designing new systems when the solution is not known beforehand. For software product solutions, the integration of our products (for example, firmware for mobile phones) requires a straightforward approach, providing integration kits that include comprehensive documentation, libraries, and source code. We work with the customer to guarantee conformance to a standard and to ensure that third-party developers can expect a consistent set of haptically enabled devices in the field.

Our research and development efforts have been focused on technology development, including hardware, software, control algorithms, and design. We have entered into numerous contracts with corporations and government agencies that help fund advanced research and development. Our government contracts permit us to retain ownership of the technology developed under the contracts, provided that we supply the applicable government agency a license to use the technology for noncommercial purposes.

For the years ended December 31, 2005, 2004, and 2003, our research and development expenses were $6.0 million, $8.0 million, and $7.9 million, respectively.

Intellectual Property

We believe that intellectual property protection is crucial to our business. We rely on a combination of patents, copyrights, trade secrets, trademarks, nondisclosure agreements with employees and third-parties, licensing arrangements, and other contractual agreements with third parties to protect our intellectual property.

We and our wholly owned subsidiaries hold more than 500 issued or pending patents in the U.S. and other countries covering various aspects of our hardware and software technologies. Some of our current U.S. patents begin to expire starting in 2007.

Where we feel it is appropriate, we will engage the legal system to protect our intellectual property rights. For example, we filed a complaint against Sony Computer Entertainment, Inc. and Sony Computer Entertainment of America, Inc. (collectively “Sony Computer Entertainment”) on February 11, 2002 in the U.S. District Court for the Northern District Court of California. On September 21, 2004, a jury returned a verdict favorable to us in our patent infringement suit against Sony Computer Entertainment. Judgment was entered in our favor and we were awarded $82.0 million in past damages, and pre-judgment interest in the amount of $8.7 million, for a total of $90.7 million. Additionally, the Court issued a permanent injunction (stayed pending appeal) against the manufacture, use, sale, or import into the United States of the infringing Sony PlayStation system. Sony Computer Entertainment has appealed the judgment to the United States Court of Appeals for the Federal Circuit. Due to the inherent uncertainties of litigation, we cannot accurately predict the ultimate outcome of this litigation. See Item 3. “Legal Proceedings” for further details and discussion.

Item 1A. Risk Factors

You should carefully consider the following risks and uncertainties, as well as other information in this report and our SEC filings, before you invest in our common stock. Investing in our common stock involves risk. If any of the following risks or uncertainties actually occur, our business, financial condition, or results of operations could be materially adversely affected. The following risks and uncertainties are not the only ones facing us. Additional risks and uncertainties of which we are unaware or that we currently believe are immaterial could also materially adversely affect our business, financial condition, or results of operations. In any case, the trading price of our common stock could decline, and you could lose all or part of your investment. See also the Forward-looking Statements discussion in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Factors That May Affect Future Results

Company Risks

We had an accumulated deficit of $127 million as of December 31, 2005, have a history of losses, will experience losses in the future, and may not achieve or maintain profitability.

Since 1997, we have incurred losses in every fiscal quarter. We will need to generate significant ongoing revenue to achieve and maintain profitability. We anticipate that our expenses will increase in the foreseeable future as we:


	•	protect and enforce our intellectual property, including the costs of our continuing litigation against Sony Computer Entertainment;

	•	continue to develop our technologies;

	•	attempt to expand the market for touch-enabled technologies and products;

	•	increase our sales and marketing efforts; and

	•	pursue strategic relationships.

If our revenues grow more slowly than we anticipate or if our operating expenses exceed our expectations, we may not achieve or maintain profitability.

Our convertible debentures provide for various events of default and change of control transactions that would entitle the selling stockholders to require us to repay the entire amount owed in cash. If an event of default or change of control occurs, we may be unable to immediately repay the amount owed, and any repayment may leave us with little or no working capital in our business.

Our convertible debentures provide for various events of default, such as the termination of trading of our common stock on the Nasdaq Stock Market and specified change of control transactions. If an event of default or change of control occurs prior to maturity, we may be required to redeem all or part of the convertible debentures, including payment of applicable interest and penalties. Some of the events of default include matters over which we may have some, little, or no control. Many other events of default are described in the agreements we executed when we issued the convertible debentures. If an event of default or a change of control occurs, we may be required to repay the entire amount, plus liquidated damages, in cash. Any such repayment could leave us with little or no working capital for our business. We have not established a sinking fund for payment of our outstanding convertible debentures, nor do we anticipate doing so.

Our current litigation against Sony Computer Entertainment and others is expensive, disruptive, and time consuming, and will continue to be, until resolved, and regardless of whether we are ultimately successful, could adversely affect our business.

Immersion Corporation vs. Microsoft Corporation, Sony Computer Entertainment Inc. and Sony Computer Entertainment of America, Inc.

On February 11, 2002, we filed a complaint against Microsoft Corporation (“Microsoft”), Sony Computer Entertainment, Inc., and Sony Computer Entertainment of America, Inc. (collectively “Sony Computer Entertainment”) in the U.S. District Court for the Northern District Court of California alleging infringement of U.S. Patent Nos. 5,889,672 and 6,275,213. The case was assigned to United States District Judge Claudia Wilken. On April 4, 2002, Sony Computer Entertainment and Microsoft answered the complaint by denying the material allegations and alleging counterclaims seeking a judicial declaration that the asserted patents were invalid, unenforceable, or not infringed. Under the counterclaims, the defendants were also seeking damages for attorneys’ fees. On October 8, 2002, we filed an amended complaint, withdrawing the claim under the U.S. Patent No. 5,889,672 and adding claims under a new patent, U.S. Patent No. 6,424,333.

On July 28, 2003, we announced that we had settled our legal differences with Microsoft, and both parties agreed to dismiss all claims and counterclaims relating to this matter as well as assume financial responsibility for their respective legal costs with respect to the lawsuit between us and Microsoft.

On August 16, 2004, the trial against Sony Computer Entertainment commenced. On September 21, 2004, the jury returned its verdict in favor of us. The jury found all the asserted claims of the patents valid and infringed. The jury awarded us damages in the amount of $82.0 million. On January 10, 2005, the Court awarded us prejudgment interest on the damages the jury awarded at the applicable prime rate. The Court further ordered Sony Computer Entertainment to pay us a compulsory license fee at the rate of 1.37%, the ratio of the verdict amount to the amount of sales of infringing products, effective as of July 1, 2004 and through the date of Judgment. On February 9, 2005, the Court ordered that Sony Computer Entertainment provide us with sales data 15 days after the end of each quarter and clarifying that Sony Computer Entertainment shall make the ordered payment 45 days after the end of the applicable quarter. Sony Computer Entertainment has made quarterly payments to us pursuant to the Court’s orders. Although we have received payments, we may be required to return them and any future payments based on the outcome of the appeals process.

On February 9, 2005, Sony Computer Entertainment filed a Notice of Appeal to the United States Court of Appeals for the Federal Circuit to appeal the Court’s January 10, 2005 order, and on February 10, 2005 Sony Computer Entertainment filed an Amended Notice of Appeal to include an appeal from the Court’s February 9, 2005 order.

entered judgment in our favor and awarded us $82.0 million in past damages, and pre-judgment interest in the amount of $8.7 million, for a total of $90.7 million. We were also awarded certain court costs. Court costs do not include attorneys’ fees.

Additionally, the Court issued a permanent injunction against the manufacture, use, sale, or import into the United States of the infringing Sony Computer Entertainment PlayStation system consisting of the PlayStation consoles, Dual Shock controllers, and the 47 games found by the jury to infringe our patents. The Court stayed the permanent injunction pending appeal to the United States Court of Appeals for the Federal Circuit. The Court further ordered Sony Computer Entertainment to pay a compulsory license fee at the rate of 1.37% for the duration of the stay of the permanent injunction at the same rate and conditions as previously awarded in its interim January 10, 2005 and February 9, 2005 Orders. On April 7, 2005 pursuant to a stipulation of the parties, the Court entered an Amended Judgment to clarify that the Judgment in favor of us and against Sony Computer Entertainment also encompassed Sony Computer Entertainment’s counterclaims for declaratory relief on invalidity and unenforceability, as well as non-infringement.

Sony Computer Entertainment also filed further motions seeking “judgment as a matter of a law” (JMOL) or for a new trial, and a motion for a stay of an accounting and execution of the Judgment. On May 17, 2005, Judge Wilken denied these motions. On April 27, 2005, the Court granted Sony Computer Entertainment’s request to approve a supersedeas bond, secured by a cash deposit with the Court in the amount of $102.5 million, to obtain a stay of enforcement of the Court’s Amended Judgment pending appeal. On May 17, 2005, the Court issued a minute order stating that in lieu of the supersedeas bond the Court would allow Sony Computer Entertainment to place the funds on deposit with the Court in an escrow account subject to acceptable escrow instructions. The parties have negotiated an agreement pursuant to which the funds on deposit with the Court may be deposited in an escrow account at JP Morgan Chase.

On May 17, 2005, Sony Computer Entertainment filed a Request for Inter Partes Reexamination of the ‘333 Patent with the United States Patent and Trademark Office. On May 19, 2005, Sony Computer Entertainment filed a similar Request for reexamination of the ‘213 Patent. On July 6, 2005, we filed a Petition to dismiss, stay or alternatively to suspend both of the requests for reexamination, based at least on the grounds that a final judgment has already been entered by a United States district court, and that the PTO’s current inter partes reexamination procedures deny due process of law. The PTO denied the first petition, and we filed a second petition on September 9, 2005. On November 17, 2005, the PTO granted our petition, and suspended the inter partes reexaminations until such time as the parallel court proceedings warrant termination or resumption of the PTO examination and prosecution proceedings. On December 13, 2005, Sony Computer Entertainment filed a third petition requesting permission to file an additional inter partes reexamination on the claims of the ‘333 and ‘213 Patents for which reexamination was not requested in Sony Computer Entertainment’s original requests for reexamination; we have opposed this petition. The PTO has not yet issued a decision on Sony Computer Entertainment’s third petition. Sony Computer Entertainment also filed ex parte reexamination requests on the claims of the ‘333 and ‘213 Patents on December 13, 2005.

On June 16, 2005, Sony Computer Entertainment filed a Notice of Appeal from the District Court Judgment to the United States Court of Appeals for the Federal Circuit. The appeals of the January and February orders regarding the compulsory license have been consolidated with this appeal of the Judgment. Sony Computer Entertainment’s Opening Brief was filed on October 21, 2005; we filed an Opposition Brief on December 5, 2005. Due to the cross appeal by Internet Services LLC (“ISLLC”) (see below), the Federal Circuit allowed us to file a Substitute Opposition Brief on February 17, 2006 responding to the briefs filed by both Sony Computer Entertainment and ISLLC. We expect the briefing for the appeal to be concluded by all parties by the end of March 2006.

On July 21, 2005, Sony Computer Entertainment filed a motion in the District Court before Judge Wilken seeking relief from the final judgment under Rule 60(b) of the Federal Rules of Civil Procedure on the grounds of alleged fraud and “newly discovered evidence” of purported prior art which Sony Computer Entertainment contends we concealed and withheld attributable to Mr. Craig Thorner, a named inventor on three patents that Sony Computer Entertainment urged as a basis for patent invalidity during the trial. We dispute and intend to vigorously defend ourselves against these allegations. Briefing is complete, and a hearing was held before Judge Wilken on

January 20, 2006. On March 8, 2006, the Court denied Sony Computer Entertainment’s motion pursuant to Rule 60(b) of the Federal Rules of Civil Procedure in its entirety.

Due to the inherent uncertainties of litigation, we cannot accurately predict how the Court of Appeals will decide the appeal. We anticipate that the litigation will continue to be costly, and there can be no assurance that we will be able to recover the costs we incur in connection with the litigation. We expense litigation costs as incurred and only accrue for costs that have been incurred but not paid to the vendor as of the financial statement date. The litigation has diverted, and is likely to continue to divert, the efforts and attention of some of our key management and personnel. As a result, until such time as it is resolved, the litigation could adversely affect our business. Further, any unfavorable outcome could adversely affect our business.

In the event we settle our lawsuit with Sony Computer Entertainment, we will be obligated to pay certain sums to Microsoft as described in Note 9 to the consolidated financial statements. If Sony Computer Entertainment ultimately were successful on appeal or in the reexamination process, the Judgment may be put at risk, assets relating to the patents in the lawsuit may be impaired, and Sony Computer Entertainment may seek additional relief, such as attorneys’ fees.

Internet Services LLC Litigation

On October 20, 2004, ISLLC, a Company licensee and cross-claim defendant against whom Sony Computer Entertainment had filed a claim seeking declaratory relief, filed claims against us alleging that we breached a contract with ISLLC by suing Sony Computer Entertainment for patent infringement relating to haptically-enabled software whose topics or images are allegedly age-restricted, for judicial apportionment of damages awarded by the jury between ISLLC and us, and for a judicial declaration with respect to ISLLC’s rights and duties under agreements with us. On December 29, 2004, the Court issued an order dismissing ISLLC’s claims against Sony Computer Entertainment with prejudice and dismissing ISLLC’s claims against us without prejudice to ISLLC filing a new complaint “if it can do so in good faith without contradicting, or repeating the deficiency of, its complaint.”

On January 12, 2005, ISLLC filed Amended Cross-Claims and Counterclaims against us that contained similar claims. ISLLC also realleged counterclaims against Sony Computer Entertainment. On January 28, 2005, we filed a motion to dismiss ISLLC’s Amended Cross-Claims and a motion to strike ISLLC’s Counterclaims against Sony Computer Entertainment. On March 24, 2005 the Court issued an order dismissing ISLLC’s claims with prejudice as to ISLLC’s claim seeking a declaratory judgment that it is an exclusive licensee under the ’213 and ’333 patents and as to ISLLC’s claim seeking “judicial apportionment” of the damages verdict in the Sony Computer Entertainment case. The Court’s order further dismissed ISLLC’s claims without prejudice as to ISLLC’s breach of contract and unjust enrichment claims.

ISLLC filed a notice of appeal of those orders with the Federal Circuit on April 18, 2005. ISLLC’s appeal has been consolidated with Sony Computer Entertainment’s appeal. ISLLC filed its Opening Brief in December 2005. As noted above, the Federal Circuit allowed us to file a Substitute Opposition Brief on February 17, 2006 responding to the briefs filed by both Sony Computer Entertainment and ISLLC; we expect the briefing for the appeal to be concluded by all parties by the end of March 2006.

On February 8, 2006, ISLLC filed a lawsuit against us in the Superior Court of Santa Clara County. ISLLC’s complaint seeks a share of our Judgment and recovery against Sony Computer Entertainment and of the Microsoft settlement proceeds, and generally restates the claims already adjudicated in District Court. Our response to the complaint is due on March 16, 2006.

Litigation regarding intellectual property rights could be expensive, disruptive, and time consuming; could result in the impairment or loss of portions of our intellectual property; and could adversely affect our business.

Intellectual property litigation, whether brought by us or by others against us, has been in the past, and could result in the future, in the expenditure of significant financial resources and the diversion of management’s time and efforts. From time to time, we initiate claims against third parties that we believe infringe our intellectual property

rights. We intend to enforce our intellectual property rights vigorously and may initiate litigation against parties that we believe are infringing our intellectual property rights if we are unable to resolve matters satisfactorily through negotiation. Litigation brought to protect and enforce our intellectual property rights could be costly, time-consuming, and distracting to management and could result in the impairment or loss of portions of our intellectual property. In addition, any litigation in which we are accused of infringement may cause product shipment delays, require us to develop non-infringing technologies, or require us to enter into royalty or license agreements even before the issue of infringement has been decided on the merits. If any litigation were not resolved in our favor, we could become subject to substantial damage claims from third parties and indemnification claims from our licensees. We and our licensees could be enjoined from the continued use of the technologies at issue without a royalty or license agreement. Royalty or license agreements, if required, might not be available on acceptable terms, or at all. If a third party claiming infringement against us prevailed, and we could not develop non-infringing technologies or license the infringed or similar technologies on a timely and cost-effective basis, our expenses would increase and our revenues could decrease.

We attempt to avoid infringing known proprietary rights of third parties. However, third parties may hold, or may in the future be issued, patents that could be infringed by our products or technologies. Any of these third parties might make a claim of infringement against us with respect to the products that we manufacture and the technologies that we license. From time to time, we have received letters from companies, several of which have significantly greater financial resources than we do, asserting that some of our technologies, or those of our licensees, infringe their intellectual property rights. Certain of our licensees have received similar letters from these or other companies. Such letters or subsequent litigation may influence our licensees’ decisions whether to ship products incorporating our technologies. In addition, such letters may cause a dispute between our licensees and us over indemnification for the infringement claim. Any of these notices, or additional notices that we or our licensees could receive in the future from these or other companies, could lead to litigation against us, either regarding the infringement claim or the indemnification claim.

We have acquired patents from third parties and also license some technologies from third parties. We must rely upon the owners of the patents or the technologies for information on the origin and ownership of the acquired or licensed technologies. As a result, our exposure to infringement claims may increase. We generally obtain representations as to the origin and ownership of acquired or licensed technologies and indemnification to cover any breach of these representations. However, representations may not be accurate and indemnification may not provide adequate compensation for breach of the representations. Intellectual property claims against our licensees, or us, whether or not they have merit, could be time-consuming to defend, cause product shipment delays, require us to pay damages, harm existing license arrangements, or require us or our licensees to cease utilizing the technologies unless we can enter into royalty or licensing agreements. Royalty or licensing agreements might not be available on terms acceptable to us or at all. Furthermore, claims by third parties against our licensees could also result in claims by our licensees against us under the indemnification provisions of our licensees’ agreements with us.

The terms in our agreements may be construed by our licensees in a manner that is inconsistent with the rights that we have granted to other licensees, or in a manner that may require us to incur substantial costs to resolve conflicts over license terms.

We have entered into, and we expect to continue to enter into, agreements pursuant to which our licensees are granted rights under our technology and intellectual property. These rights may be granted in certain fields of use, or with respect to certain market sectors or product categories, and may include exclusive rights or sublicensing rights. We refer to the license terms and restrictions in our agreements, including, but not limited to, field of use definitions, market sector, and product category definitions, collectively as “License Provisions.”

Due to the continuing evolution of market sectors, product categories, and licensee business models, and to the compromises inherent in the drafting and negotiation of License Provisions, our licensees may, at some time during the term of their agreements with us, interpret License Provisions in their agreements in a way that is different from our interpretation of such License Provisions, or in a way that is in conflict with the rights that we have granted to other licensees. Such interpretations by our licensees may lead to (a) claims that we have granted rights to one licensee which are inconsistent with the rights that we have granted to another licensee, and/or (b) claims by one licensee against another licensee that may result in our incurring indemnification or other obligations or liabilities.

In addition, after we enter into an agreement, it is possible that markets and/or products, or legal and/or regulatory environments, will evolve in a manner that we did not foresee or was not foreseeable at the time we entered into the agreement. As a result, in the agreement, we may have granted rights that will preclude or restrict our exploitation of potentially lucrative new opportunities that arise after the execution of the agreement.

Product liability claims could be time-consuming and costly to defend and could expose us to loss.

Our products or our licensees’ products may have flaws or other defects that may lead to personal or other injury claims. If products that we or our licensees sell cause personal injury, financial loss, or other injury to our or our licensees’ customers, the customers or our licensees may seek damages or other recovery from us. Any claims against us would be time-consuming, expensive to defend, and distracting to management, and could result in damages and injure our reputation and/or the reputation of our products, or the reputation of our licensees or their products. This damage could limit the market for our and our licensees’ products and harm our results of operations.

In the past, manufacturers of peripheral products including certain gaming products such as joysticks, wheels, or gamepads, have been subject to claims alleging that use of their products has caused or contributed to various types of repetitive stress injuries, including carpal tunnel syndrome. We have not experienced any product liability claims to date. Although our license agreements typically contain provisions designed to limit our exposure to product liability claims, existing or future laws or unfavorable judicial decisions could limit or invalidate the provisions.

If the settlement on our current class action lawsuit falls through, the continuing lawsuit could be

expensive, disruptive, and time consuming to defend against, and if we are not successful, could adversely affect our business.

We are involved in legal proceedings relating to a class action lawsuit filed on November 9, 2001, In re Immersion Corporation Initial Public Offering Securities Litigation, No. Civ. 01-9975 (S.D.N.Y.), related to In re Initial Public Offering Securities Litigation, No. 21 MC 92 (S.D.N.Y.). The named defendants are Immersion and three of our current or former officers or directors (the “Immersion Defendants”) and certain underwriters of our November 12, 1999 IPO. Subsequently, two of the individual defendants stipulated to a dismissal without prejudice.

The operative amended complaint is brought on purported behalf of all persons who purchased our common stock from the date of our IPO through December 6, 2000. It alleges liability under Sections 11 and 15 of the Securities Act of 1933 and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on the grounds that the registration statement for the IPO did not disclose that: (1) the underwriters agreed to allow certain customers to purchase shares in the IPO in exchange for excess commissions to be paid to the underwriters; and (2) the underwriters arranged for certain customers to purchase additional shares in the aftermarket at predetermined prices. The complaint also appears to allege that false or misleading analyst reports were issued. The complaint does not claim any specific amount of damages.

Similar allegations were made in other lawsuits challenging over 300 other initial public offerings and follow-on offerings conducted in 1999 and 2000. The cases were consolidated for pretrial purposes. On February 19, 2003, the Court ruled on all defendants’ motions to dismiss. The motion was denied as to claims under the Securities Act of 1933 in the case involving us, as well as in all other cases (except for 10 cases). The motion was denied as to the claim under Section 10(b) as to us, on the basis that the complaint alleged that we had made acquisition(s) following the IPO. The motion was granted as to the claim under Section 10(b), but denied as to the claim under Section 20(a), as to the remaining individual defendant.

We and most of the issuer defendants have settled with the plaintiffs. In this settlement, plaintiffs have dismissed and released all claims against the Immersion Defendants, in exchange for a contingent payment by the insurance companies collectively responsible for insuring the issuers in all of the IPO cases, and for the assignment or surrender of certain claims we may have against the underwriters. The Immersion Defendants will not be required to make any cash payments in the settlement, unless the pro rata amount paid by the insurers in the settlement exceeds the amount of the insurance coverage, a circumstance which we believe is remote. The settlement will require approval of the Court, which cannot be assured, after class members are given the opportunity to object to the settlement or opt out of the settlement.

If our facilities were to experience catastrophic loss, our operations would be seriously harmed.

Our facilities could be subject to a catastrophic loss such as fire, flood, earthquake, power outage, or terrorist activity. California has experienced problems with its power supply in recent years. As a result, we have experienced utility cost increases and may experience unexpected interruptions in our power supply that could have a material adverse effect on our sales, results of operations, and financial condition. In addition, a substantial portion of our research and development activities, manufacturing, our corporate headquarters, and other critical business operations are located near major earthquake faults in San Jose, California, an area with a history of seismic events. Any such loss at our facilities could disrupt our operations, delay production, shipments, and revenue, and result in large expenses to repair and replace the facility. While we believe that we maintain insurance sufficient to cover most long-term potential losses at our facilities, our existing insurance may not be adequate for all possible losses.

Industry and Technology Risks

We have little or no control or influence on our licensees’ design, manufacturing, promotion, distribution, or pricing of their products incorporating our touch-enabling technologies, upon which we generate

royalty revenue.

A key part of our business strategy is to license our intellectual property to companies that manufacture and sell products incorporating our touch-enabling technologies. Sales of those products generate royalty and license revenue for us. For the years ended December 31, 2005, 2004, and 2003, 37%, 37%, and 30%, respectively, of our total revenues were royalty and license revenues. However, we do not control or influence the design, manufacture, quality control, promotion, distribution, or pricing of products that are manufactured and sold by our licensees. In addition, we generally do not have commitments from our licensees that they will continue to use our technologies in current or future products. As a result, products incorporating our technologies may not be brought to market, meet quality control standards, achieve commercial acceptance, or generate meaningful royalty revenue for us. For us to generate royalty revenue, licensees that pay us per-unit royalties must manufacture and distribute products incorporating our touch-enabling technologies in a timely fashion and generate consumer demand through marketing and other promotional activities. Products incorporating our touch-enabling technologies are generally more difficult to design and manufacture, which may cause product introduction delays or quality control problems. If our licensees fail to stimulate and capitalize upon market demand for products that generate royalties for us, or if products are recalled because of quality control problems, our revenues will not grow and could decline. Alternatively, if a product that incorporates our touch-enabling technologies achieves widespread market acceptance, the product manufacturer may elect to stop making it rather than pay us royalties based on sales of the product.

Peak demand for products that incorporate our technologies, especially in the video console gaming and computer gaming peripherals market, typically occurs in the fourth calendar quarter as a result of increased demand during the year-end holiday season. If our licensees do not ship products incorporating our touch-enabling technologies in a timely fashion or fail to achieve strong sales in the fourth quarter of the calendar year, we may not receive related royalty and license revenue.

Most of our current gaming royalty revenues come from third-party peripheral makers who make licensed gaming products designed for use with popular video game console systems from Microsoft, Sony, and Nintendo. Video game console systems are closed, proprietary systems, and video game console system makers typically impose certain requirements or restrictions on third-party peripheral makers who wish to make peripherals that will be compatible with a particular video game console system. These requirements and restrictions could be in the form of hardware technical specifications, software technical specifications, security specifications, component vendor specifications, licensing terms and conditions, or other forms. If third-party peripheral makers can not or are not allowed to obtain or satisfy these requirements or restrictions, our gaming royalty revenues could be significantly reduced. Furthermore, should a significant video game console maker choose to omit touch-enabling capabilities from its console system, it may very well lead our gaming licensees to stop making products with touch-enabling capabilities, thereby significantly reducing our gaming royalty revenues. The recently launched Microsoft Xbox 360 ships with touch-enabling capabilities built-in, and the upcoming next generation Nintendo Revolution

has been reported by Nintendo to have touch-enabling capabilities. However, no announcements have been made regarding the touch-enabling capabilities of the upcoming next-generation Sony console system.

Microsoft launched its next-generation Xbox 360 video game console in November 2005, and it is anticipated that Sony and Nintendo will launch their new next-generation video game console systems in 2006. Historically, according to data from the NPD Group, sales of console peripherals by third-party suppliers grow to about 65% or more of total market share near the end of the life cycle of a console system. When next-generation console systems are released third-party peripheral product sales initially account for 30% or less of total market share. This percentage increases as the console model ages. Most of our current gaming royalty revenue is from third-party peripheral makers. Consequently, with the new console introductions already beginning and continuing to take place over the year, our gaming royalty revenue will likely decrease from current levels, which may hurt our business.

Because we have a fixed payment license with Microsoft, our royalty revenue from licensing in the

gaming market and other consumer markets might decline if Microsoft increases its volume of sales of

touch-enabled gaming products and consumer products at the expense of our other licensees.

Under the terms of our present agreement with Microsoft, Microsoft receives a royalty-free, perpetual, irrevocable license to our worldwide portfolio of patents. This license permits Microsoft to make, use, and sell hardware, software, and services, excluding specified products, covered by our patents. We also granted to Microsoft a limited right, under our patents relating to touch technologies, to sublicense specified rights, excluding rights to excluded products and peripheral devices, to third-party customers of Microsoft’s or Microsoft’s subsidiaries’ products (other than Sony Corporation, Sony Computer Entertainment Inc., Sony Computer Entertainment of America Inc., and their subsidiaries). In exchange, for the grant of these rights and the rights included in a separate Sublicense Agreement, Microsoft paid us a one-time payment of $20.0 million. We will not receive any further revenues or royalties from Microsoft under our current agreement with Microsoft. Microsoft has a significant share of the market for touch-enabled console gaming computer peripherals and is pursuing other consumer markets such as mobile phones and PDAs. Microsoft has significantly greater financial, sales, and marketing resources, as well as greater name recognition and a larger customer base than our other licensees. In the event that Microsoft increases its share of these markets, our royalty revenue from other licensees in these market segments might decline.

For the Microsoft Xbox 360 video console system launched in November 2005, Microsoft has, to date, not licensed the rights to produce wireless controllers to any third-party peripheral makers. Wireless game controllers account for a significant and growing portion of our royalty revenue, including revenue from Logitech and Mad Catz. Therefore, by retaining the market for wireless Xbox 360 game controllers exclusively for itself, Microsoft will likely significantly increase its market share of all aftermarket game controller sales, the effect of which is likely to reduce our gaming royalty revenue.

Logitech accounts for a significant portion of our revenue and the failure of Logitech to achieve sales volumes for its gaming peripheral products that incorporate our touch-enabling technologies may reduce our total revenue.

Logitech accounts for a significant portion of our revenue. For the years ended December 31, 2005, 2004, and 2003, 11%, 10%, and 5%, respectively, of our total revenues were derived from Logitech. We expect that Logitech will continue to account for a significant portion of our total revenue. If Logitech’s sales volumes for its computer and console gaming peripheral products that incorporate our technologies decline, our total revenue may decline.

Medtronic accounts for a significant portion of our revenues and a reduction in sales to Medtronic, or a reduction in development work for Medtronic, may reduce our total revenue.

Medtronic accounts for a significant portion of our revenue. For the years ended December 31, 2005, 2004, and 2003, 11%, 17%, and 18%, respectively, of our total revenues were derived from Medtronic. If our product sales to Medtronic decline, and/or Medtronic reduces the development activities we perform, then our total revenue may decline.

Automotive royalties will be reduced if BMW were to abandon its iDrive system or remove our technology from the iDrive.

Our largest royalty stream from the automotive industry is currently from BMW for its iDrive controller. Press reviews of this system have been largely negative and critical of the system’s complex user interface, which we did not design. Nevertheless, this negative press may cause BMW to abandon the iDrive controller or to redesign it and/or remove our technology from it. The design cycle time for major automotive systems like iDrive is typically two to five years. One or more of the current BMW product lines may go through replacement or redesign and during that cycle the iDrive controller may be replaced or removed. Historically, BMW has often launched its newest technology in its 7 Series. We also believe that the current 7 series is due for redesign by 2008 and that our technology may, or may not, be part of the redesigned iDrive. A decline in our royalties from BMW will harm our business.

We depend on third-party suppliers, and our revenue and/or results of operations could suffer if we fail to manage supplier issues properly.

Our operations depend on our ability to anticipate our needs for components and products for a wide variety of systems, products, and services, and our suppliers’ ability to deliver sufficient quantities of quality components, products, and services at reasonable prices in time for us to meet critical schedules. We may experience a shortage of, or a delay in receiving, certain supplies as a result of strong demand, capacity constraints, supplier financial weaknesses, disputes with suppliers, other problems experienced by suppliers, or problems faced during the transition to new suppliers. If shortages or delays persist, the price of these supplies may increase, we may be exposed to quality issues, or the supplies may not be available at all. We may not be able to secure enough supplies at reasonable prices or of acceptable quality to build products or provide services in a timely manner in the quantities or according to the specifications needed. We could lose time-sensitive sales, incur additional freight costs, or be unable to pass on price increases to our customers. If we cannot adequately address supply issues, we might have to reengineer some products or service offerings, resulting in further costs and delays.

Additionally, our use of single source suppliers for certain components could exacerbate our supplier issues. We obtain a significant number of components from single sources due to technology, availability, price, quality, or other considerations. In addition, new products that we introduce may use custom components obtained from only one source initially, until we have evaluated whether there is a need for additional suppliers. The performance of such single source suppliers may affect the quality, quantity, and price of supplies to us. Accordingly, our revenue and/or results of operations could be adversely impacted by such events.

Because personal computer peripheral products that incorporate our touch-enabling technologies

currently must work with Microsoft’s operating system software, our costs could increase and our

revenues could decline if Microsoft modifies its operating system software.

Our hardware and software technologies for personal computer peripheral products that incorporate our touch-enabling technologies are currently compatible with Microsoft’s Windows 2000, Windows Me, and Windows XP operating systems, including DirectX, Microsoft’s entertainment applications programming interface. Modifications and new versions of Microsoft’s operating system (including DirectX and the upcoming Windows Vista anticipated to launch in late 2006) may require that we and/or our licensees modify the touch-enabling technologies to be compatible with Microsoft’s modifications or new versions, and this could cause delays in the release of products by our licensees. If Microsoft modifies its software products in ways that limit the use of our other licensees’ products, our costs could increase and our revenues could decline.

Reduced spending by corporate or university research and development departments may adversely affect sales of our three-dimensional and professional products.

Any economic downturn could lead to a reduction in corporations’ or university budgets for research and development in sectors, including the automotive and aerospace sectors, which use our three-dimensional and professional products. Sales of our three-dimensional and professional products, including our CyberGlove line of

whole-hand sensing gloves and our MicroScribe line of digitizers, could be adversely affected by cuts in corporate research and development budgets.

Competition between our products and our licensees’ products may reduce our revenue.

Rapid technological change, short product life cycles, cyclical market patterns, declining average selling prices, and increasing foreign and domestic competition characterize the markets in which we and our licensees compete. We believe that competition in these markets will continue to be intense and that competitive pressures will drive the price of our products and our licensees’ products downward. These price reductions, if not offset by increases in unit sales or productivity, will cause our revenues to decline.

We face competition from unlicensed products as well. Our licensees or other third parties may seek to develop products using our intellectual property or develop alternative designs that attempt to circumvent our intellectual property, which they believe do not require a license under our intellectual property. These potential competitors may have significantly greater financial, technical, and marketing resources than we do, and the costs associated with asserting our intellectual property rights against such products and such potential competitors could be significant. Moreover, if such alternative designs were determined by a court not to require a license under our intellectual property rights, competition from such unlicensed products could limit or reduce our revenues.

We have experienced significant change in our business, and our failure to manage the complexities

associated with the changing economic environment and technology landscape could harm our business.

Any future periods of rapid economic and technological change may place significant strains on our managerial, financial, engineering, and other resources. In particular, because our technologies are complex, if the economy weakens, an unusually high level of managerial effectiveness in anticipating, planning, coordinating, and meeting our operational needs as well as the needs of our licensees may be required.

The market for certain touch-enabling technologies and touch-enabled products is at an early stage and if market demand does not develop, we may not achieve or sustain revenue growth.

The market for certain of our touch-enabling technologies and certain of our licensees’ touch-enabled products is at an early stage. If we and our licensees are unable to develop demand for touch-enabling technologies and touch-enabled products, we may not achieve or sustain revenue growth. We cannot accurately predict the growth of the markets for these technologies and products, the timing of product introductions, or the timing of commercial acceptance of these products.

Even if our touch-enabling technologies and our licensees’ touch-enabled products are ultimately widely adopted, widespread adoption may take a long time to occur. The timing and amount of royalties and product sales that we receive will depend on whether the products marketed achieve widespread adoption and, if so, how rapidly that adoption occurs.

We expect that we will need to pursue extensive and expensive marketing and sales efforts to educate prospective licensees, component customers, and end users about the uses and benefits of our technologies and to persuade software developers to create software that utilizes our technologies. Negative product reviews or publicity about our products, our licensees’ products, haptic features, or haptic technology in general could have a negative impact on market adoption, our revenue, and/or our ability to license our technologies in the future.

If we are unable to enter into new licensing arrangements with our existing licensees, and with additional third-party manufacturers for our touch-enabling technologies, our royalty revenue may not grow.

Our revenue growth is significantly dependent on our ability to enter into new licensing arrangements. Our failure to enter into new or renewal of licensing arrangements will cause our operating results to suffer. We face numerous risks in obtaining new licenses on terms consistent with our business objectives and in maintaining, expanding, and supporting our relationships with our current licensees. These risks include:


	•	the lengthy and expensive process of building a relationship with potential licensees;


	•	the fact that we may compete with the internal design teams of existing and potential licensees;

	•	difficulties in persuading product manufacturers to work with us, to rely on us for critical technology, and to disclose to us proprietary product development and other strategies;

	•	challenges in demonstrating the compelling value of our technologies in new applications like mobile phones and touchscreens;

	•	difficulties in persuading existing and potential licensees to bear the development costs and risks necessary to incorporate our technologies into their products;

	•	difficulties in signing up new automotive licensees for not-yet-commercialized technology when their components suppliers may not yet be able to meet the car companies’ stringent quality and parts availability standards;

	•	difficulty in signing up new gaming licensees, as well as losing our existing gaming licensees, if we are not successful in the litigation with Sony Computer Entertainment; and

	•	reluctance of content developers, mobile phone manufacturers, and service providers to sign license agreements without a critical mass of other such inter-dependent supporters of the mobile phone industry having a license or without enough phones in the market that incorporate our technologies.

A majority of our current royalty revenue has been derived from the licensing of our portfolio of touch-enabling technologies for video game console and personal computer gaming peripherals, such as gamepads, joysticks, and steering wheels. Though substantially smaller than the market for dedicated gaming console peripherals, the market for gamepads, joysticks, and steering wheels for use with personal computers is declining and is characterized by declining average selling prices. If the console peripheral market also experiences declines in sales and selling prices, we may not achieve royalty revenue growth.

If we fail to protect and enforce our intellectual property rights, our ability to license our technologies and generate revenues would be impaired.

Our business depends on generating revenues by licensing our intellectual property rights and by selling products that incorporate our technologies. We rely on our significant patent portfolio to protect our proprietary rights. If we are not able to protect and enforce those rights, our ability to obtain future licenses or maintain current licenses and royalty revenue could be impaired. In addition, if a court or the patent office were to limit the scope, declare unenforceable, or invalidate any of our patents, current licensees may refuse to make royalty payments or they may choose to challenge one or more of our patents. It is also possible that:


	•	our pending patent applications may not result in the issuance of patents;

	•	our patents may not be broad enough to protect our proprietary rights; and

	•	effective patent protection may not be available in every country in which our licensees do business.

We also rely on licenses, confidentiality agreements, other contractual agreements, and copyright, trademark, and trade secret laws to establish and protect our proprietary rights. It is possible that:


	•	laws and contractual restrictions may not be sufficient to prevent misappropriation of our technologies or deter others from developing similar technologies; and

	•	policing unauthorized use of our products, trademarks, and other proprietary rights would be difficult, expensive, and time-consuming, particularly overseas.

Certain terms or rights granted in our license agreements or our development contracts may limit our future revenue opportunities.

While it is not our general practice to sign license agreements that provide exclusive rights for a period of time with respect to a technology, field of use, and/or geography, or to accept similar limitations in product development contracts, we have entered into such agreements and may in the future. Although additional compensation or other

benefits may be part of the agreement, the compensation or benefits may not adequately compensate us for the limitations or restrictions we have agreed to as that particular market develops. Over the life of the exclusivity period, especially in markets that grow larger or faster than anticipated, our revenue may be limited and less than what we could have achieved in the market with several licensees or additional products available to sell to a specific set of customers.

If we are unable to continually improve and reduce the cost of our technologies, companies may not incorporate our technologies into their products, which could impair our revenue growth.

Our ability to achieve revenue growth depends on our continuing ability to improve and reduce the cost of our technologies and to introduce these technologies to the marketplace in a timely manner. If our development efforts are not successful or are significantly delayed, companies may not incorporate our technologies into their products and our revenue growth may be impaired.

If we fail to develop new or enhanced technologies for new applications and platforms, we may not be able to create a market for our technologies or our technologies may become obsolete, and our ability to grow and our results of operations might be harmed.

Our initiatives to develop new and enhanced technologies and to commercialize these technologies for new applications and new platforms may not be successful. Any new or enhanced technologies may not be favorably received by consumers and could damage our reputation or our brand. Expanding our technologies could also require significant additional expenses and strain our management, financial, and operational resources. Moreover, technology products generally have relatively short product life cycles and our current products may become obsolete in the future. Our ability to generate revenues will be harmed if:


	•	we fail to develop new technologies or products;

	•	the technologies we develop infringe on third-party patents;

	•	our new technologies fail to gain market acceptance; or

	•	our current products become obsolete.

Compliance with the restriction of hazardous substances (RoHS) Directive in the European Union may increase our costs and limit our revenue opportunities.

The RoHS Directive eliminates most uses of lead, cadmium, hexavalent-chromium, mercury, and certain fire retardants in electronics placed on the market after July 1, 2006. We have not yet quantified the potential full effect of this new Directive on our products, but the Directive will require changes to some of our products that may be costly and this may have a negative impact on our revenues and results of operations. We are currently in discussions with our suppliers and working with them so that we can be in compliance as of the effective date of the RoHS Directive. If we are unable to, or decide not to make our products compliant by the effective date, we will not be able to ship them in the European Union and/or any other region that adopts the Directive until such time that they are compliant, and this may limit our revenue opportunities.

The higher cost of products incorporating our touch-enabling technologies may inhibit or prevent their widespread adoption.

Personal computer and console gaming peripherals, mobile phones, touchscreens, and automotive and industrial controls incorporating our touch-enabling technologies can be more expensive than similar competitive products that are not touch-enabled. Although major manufacturers, such as ALPS Electric Co., Ltd., BMW, Logitech, Microsoft, and Samsung have licensed our technologies, the greater expense of development and production of products containing our touch-enabling technologies as compared to non-touch-enabled products may be a significant barrier to the widespread adoption and sale of touch-enabled products.

If we fail to increase sales of our medical simulation devices, our financial condition and operations may suffer.

Our medical simulation products, such as our Endovascular AccuTouch System and our Laparascopic Surgical Workstation, have only recently begun to be used by hospitals and medical schools to help train healthcare professionals. As a result, many of these medical institutions do not budget for such simulation devices. To increase sales of our simulation devices, we must, in addition to convincing medical institution personnel of the usefulness of the devices, persuade them to include a significant expenditure for the devices in their budgets. If these medical institutions are unwilling to budget for simulation devices or reduce their budgets as a result of cost-containment pressures or other factors, we may not be able to increase or maintain sales of medical simulators at a satisfactory rate. Any failure to increase sales of our medical simulation products will harm our business.

Third-party validation studies may not demonstrate all the benefits of our medical training simulators, which could affect customer motivation to buy.

In medical training, validation studies are generally used to confirm the usefulness of new techniques, devices, and training methods. For medical training simulators, several levels of validation are generally tested: content, concurrent, construct, and predictive. A validation study performed by a third party, such as a hospital, a teaching institution, or even an individual healthcare professional, could result in showing little or no benefit for one or more types of validation for our medical training simulators. Such validation study results published in medical journals could impact the willingness of customers to buy our training simulators, especially new simulators that have not previously been validated. Due to the time generally required to complete and publish additional validation studies (often more than a year), the negative impact on sales revenue could be significant.

Medical licensing and certification authorities may not recommend or require use of our technologies for training and/or testing purposes, significantly slowing or inhibiting the market penetration of our medical simulation technologies.

Several key medical certification bodies, including the American Board of Internal Medicine, or ABIM and the American College of Cardiology, or ACC, have great influence in recommending particular medical methodologies, including medical training and testing methodologies, for use by medical professionals. In the event that the ABIM and the ACC, as well as other, similar bodies, do not endorse medical simulation products as a training and/or testing tool, market penetration for our products could be significantly and adversely affected.

We have limited distribution channels and resources to market and sell our medical simulation and three-dimensional simulation and digitizing products, and if we are unsuccessful in marketing and selling these products, we may not achieve or sustain product revenue growth.

We have limited resources for marketing and selling medical simulation or three-dimensional simulation and digitizing products either directly or through distributors. To achieve our business objectives, we must build a balanced mixture of sales through a direct sales channel and through qualified distribution channels. The success of our efforts to sell medical simulation and three-dimensional simulation products will depend upon our ability to retain and develop a qualified sales force and effective distributor channels. We may not be successful in attracting and retaining the personnel necessary to sell and market our simulation products. A number of our distributors represent small, specialized companies and may not have sufficient capital or human resources to support the complexities of selling and supporting simulation products. There can be no assurance that our direct selling efforts will be effective, distributors will market our products successfully or, if our relationships with distributors terminate, that we will be able to establish relationships with other distributors on satisfactory terms, if at all. Any disruption in the distribution, sales, or marketing network for our simulation products could have a material adverse effect on our product revenues.

Competition in the medical market may reduce our revenue.

If the medical simulation market develops as we anticipate, we believe that we will have a greater number of competitors. This increased competition may result in the decline of our revenue and may cause us to reduce our selling prices.

Competition in the mobility or touchscreen markets may increase our costs and reduce our revenue.

If the mobility or touchscreen markets develop as we anticipate, we believe that we will face a greater number of competitors. These potential competitors may have significantly greater financial and technical resources than we do, and the costs associated with competing with such potential competitors could be significant. Additionally, increased competition may result in the reduction of our market share and/or cause us to reduce our prices, which may result in a decline in our revenue.

Automobiles incorporating our touch-enabling technologies are subject to lengthy product development periods, making it difficult to predict when and whether we will receive per unit automotive royalties.

The product development process for automobiles is very lengthy, sometimes longer than four years. We do not earn per unit royalty revenue on our automotive technologies unless and until automobiles featuring our technologies are shipped to customers, which may not occur until several years after we enter into an agreement with an automobile manufacturer or a supplier to an automobile manufacturer. Throughout the product development process, we face the risk that an automobile manufacturer or supplier may delay the incorporation of, or choose not to incorporate, our technologies into its automobiles, making it difficult for us to predict the per unit automotive royalties we may receive, if any. After the product launches, our royalties still depend on market acceptance of the vehicle or the option packages if our technology is an option (for example, a navigation unit), which is likely to be determined by many factors beyond our control.

We might be unable to retain or recruit necessary personnel, which could slow the development and deployment of our technologies.

Our ability to develop and deploy our technologies and to sustain our revenue growth depends upon the continued service of our management and other key personnel, many of whom would be difficult to replace. Management and other key employees may voluntarily terminate their employment with us at any time upon short notice. The loss of management or key personnel could delay product development cycles or otherwise harm our business.

We believe that our future success will also depend largely on our ability to attract, integrate, and retain sales, support, marketing, and research and development personnel. Competition for such personnel is intense, and we may not be successful in attracting, integrating, and retaining such personnel. Given the protracted nature of if, how, and when we collect royalties on new design contracts, it may be difficult to craft compensation plans that will attract and retain the level of salesmanship needed to secure these contracts. Some of our executive officers and key employees hold stock options with exercise prices considerably above the current market price of our common stock. Each of these factors may impair our ability to retain the services of our executive officers and key employees. Our technologies are complex and we rely upon the continued service of our existing engineering personnel to support licensees, enhance existing technologies, and develop new technologies.

Investment Risks

Our quarterly revenues and operating results are volatile, and if our future results are below the

expectations of public market analysts or investors, the price of our common stock is likely to decline.

Our revenues and operating results are likely to vary significantly from quarter to quarter due to a number of factors, many of which are outside of our control and any of which could cause the price of our common stock to decline.

These factors include:


	•	the establishment or loss of licensing relationships;

	•	the timing of payments under fixed and/or up-front license agreements;

	•	the timing of work performed under development agreements;

	•	the timing of our expenses, including costs related to litigation, stock-based awards, acquisitions of technologies, or businesses;

	•	the timing of introductions and market acceptance of new products and product enhancements by us, our licensees, our competitors, or their competitors;

	•	our ability to develop and improve our technologies;

	•	our ability to attract, integrate, and retain qualified personnel; and

	•	seasonality in the demand for our products or our licensees’ products.

Our stock price may fluctuate regardless of our performance.

The stock market has experienced extreme volatility that often has been unrelated or disproportionate to the performance of particular companies. These market fluctuations may cause our stock price to decline regardless of our performance. The market price of our common stock has been, and in the future could be, significantly affected by factors such as: actual or anticipated fluctuations in operating results; announcements of technical innovations; announcements regarding litigation in which we are involved; new products or new contracts; sales or the perception in the market of possible sales of large number of shares of our common stock by insiders or others; changes in securities analysts’ recommendations; changing circumstances regarding competitors or their customers; governmental regulatory action; developments with respect to patents or proprietary rights; inclusion in or exclusion from various stock indices; and general market conditions. In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has been initiated against that company, such as the suit currently filed against us.

Provisions in our charter documents and Delaware law could prevent or delay a change in control, which could reduce the market price of our common stock.

Provisions in our certificate of incorporation and bylaws may have the effect of delaying or preventing a change of control or changes in our management. In addition, certain provisions of Delaware law may discourage, delay, or prevent someone from acquiring or merging with us. These provisions could limit the price that investors might be willing to pay in the future for shares.

Issuance of the shares of common stock upon conversion of debentures, exercise of stock options, and exercise of warrants will dilute the ownership interest of existing stockholders and could adversely affect the market price of our common stock.

The issuance of shares of common stock in the following circumstances will dilute the ownership interest of existing stockholders: (i) upon conversion of some or all of the convertible debentures (ii) upon exercise of some or all of the stock options, and (iii) upon exercise of some or all of the warrants. Any sales in the public market of the common stock issuable upon such conversion or upon such exercises, respectively, could adversely affect prevailing market prices of our common stock. In addition, the existence of these convertible debentures, stock options, and warrants may encourage short selling by market participants.

Our major stockholders retain significant control over us, which may lead to conflicts with other

stockholders over corporate governance matters and could also affect the volatility of our stock price.

We currently have, have had in the past, and may have in the future, stockholders who retain greater than 10%, or in some cases greater than 20%, of our outstanding stock. Acting together, these stockholders would be able to exercise significant influence over matters that our stockholders vote upon, including the election of directors and

mergers or other business combinations, which could have the effect of delaying or preventing a third party from acquiring control over or merging with us. Further, if any individuals in this group elect to sell a significant portion or all of their holdings of our common stock, the trading price of our common stock could experience volatility.

We may need to raise additional capital in the future, which may result in substantial dilution to our stockholders.

We may need to raise additional capital in order to ensure a sufficient supply of cash for continued operations and litigation costs. We have taken measures to control our costs and will continue to monitor these efforts. In addition, Sony Computer Entertainment has made payments to us pursuant to the Court’s orders. Although we have received the payments, we may be required to return them and any future payments based on the outcome of an appeals process. Our plans to raise additional capital may include possible customer prepayments of certain royalty obligations in exchange for a royalty discount and/or other negotiated concessions, entering into new license agreements that require up-front license payments, and through debt or equity financing. We cannot be certain that additional financing will be available to us on favorable terms when required, or at all. Changes in equity markets over the past five years have adversely affected the ability of companies to raise equity financing and have adversely affected the markets for financing for companies with a history of losses such as ours. Additional financing may require us to take on more debt or issue additional shares of our common or preferred stock such that our existing stockholders may experience substantial dilution.

We may engage in acquisitions that could dilute stockholders’ interests, divert management attention, or cause integration problems.

As part of our business strategy, we have in the past and may in the future, acquire businesses or intellectual property that we feel could complement our business, enhance our technical capabilities, or increase our intellectual property portfolio. If we consummate acquisitions through cash and/or an exchange of our securities, our stockholders could suffer significant dilution. Acquisitions could also create risks for us, including:


	•	unanticipated costs associated with the acquisitions;

	•	use of substantial portions of our available cash to consummate the acquisitions;

	•	diversion of management’s attention from other business concerns;

	•	difficulties in assimilation of acquired personnel or operations; and

	•	potential intellectual property infringement claims related to newly acquired product lines.

Any acquisitions, even if successfully completed, might not generate significant additional revenue or provide any benefit to our business.

If we fail to comply with Nasdaq’s maintenance criteria for continued listing on the Nasdaq National Market, our common stock could be delisted.

To maintain the listing of our common stock on the Nasdaq National Market, we are required to comply with one of two sets of maintenance criteria for continued listing. Under the first set of criteria, among other things, we must maintain stockholders’ equity of at least $10 million, the market value of our “publicly held” common stock (excluding shares held by our affiliates) must be at least $5 million, and the minimum bid price for our common stock must be at least $1.00 per share. Under the second set of criteria, among other things, the market value of our common stock must be at least $50 million or we must have both $50 million in assets and $50 million in revenues, the market value of our “publicly held” shares must be at least $15 million, and the minimum bid price for our common stock must be at least $1.00 per share. As of December 31, 2005, our most recent balance sheet date, we had a deficit in stockholders’ equity, and therefore would not have been in compliance with the first set of listing criteria as of that date. Although we were in compliance with the second set of criteria, should the price of our common stock decline to the point where the aggregate value of our outstanding common stock falls below $50 million, the value of our “publicly held” shares falls below $15 million, or the bid price of our common stock falls below $1.00 per share, our shares could be delisted from the Nasdaq National Market. If we are unable to

comply with the applicable criteria and our common stock is delisted from the Nasdaq National Market, it would likely be more difficult to affect trades and to determine the market price of our common stock. In addition, delisting of our common stock could materially affect the market price and liquidity of our common stock and our future ability to raise necessary capital.

Failure to maintain effective internal controls in accordance with section 404 of the Sarbanes-Oxley Act could have a material adverse effect on our business and stock price.

If we fail to maintain the adequacy of our internal controls, as standards are modified, supplemented, or amended from time to time, we may not be able to ensure that we can conclude on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act. Failure to maintain an effective internal control environment could have a material adverse effect on our business and stock price.

Legislative actions, higher insurance cost, and potential new accounting pronouncements are likely to impact our future financial position and results of operations.

There have been regulatory changes, including the Sarbanes-Oxley Act of 2002, and there may potentially be new accounting pronouncements or additional regulatory rulings that will have an impact on our future financial position and results of operations. These changes and other legal changes, as well as proposed legislative initiatives following the Enron bankruptcy, are likely to increase general and administrative costs. In addition, insurers are likely to increase premiums as a result of high claims rates over the past year, which we expect will increase our premiums for our various insurance policies. Further, the Financial Accounting Standards Board (“FASB”) recently enacted Statement of Financial Accounting Standards (“SFAS”) No. 123R, “Share-Based Payment” (“SFAS No. 123R”) which requires us, as of January 1, 2006, to adopt a different method of determining the compensation expense of our employee stock options. SFAS No. 123R may have a significant adverse effect on our reported financial conditions and may impact the way we conduct our business. These and other potential changes could materially increase the expenses we report under generally accepted accounting principles, and adversely affect our operating results.

We believe that our existing facilities are adequate to meet our current needs.


Item 3.	*Legal Proceedings*

In re Immersion Corporation

We are involved in legal proceedings relating to a class action lawsuit filed on November 9, 2001, In re Immersion Corporation Initial Public Offering Securities Litigation, No. Civ. 01-9975 (S.D.N.Y.), related to In re Initial Public Offering Securities Litigation, No. 21 MC 92 (S.D.N.Y.). The named defendants are Immersion and three of our current or former officers or directors (the “Immersion Defendants”), and certain underwriters of our November 12, 1999 initial public offering (“IPO”). Subsequently, two of the individual defendants stipulated to a dismissal without prejudice.

The operative amended complaint is brought on purported behalf of all persons who purchased our common stock from the date of our IPO through December 6, 2000. It alleges liability under Sections 11 and 15 of the Securities Act of 1933 and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, on the grounds that the registration statement for the IPO did not disclose that: (1) the underwriters agreed to allow certain customers to purchase shares in the IPO in exchange for excess commissions to be paid to the underwriters; and (2) the underwriters arranged for certain customers to purchase additional shares in the aftermarket at predetermined prices. The complaint also appears to allege that false or misleading analyst reports were issued. The complaint does not claim any specific amount of damages.

Similar allegations were made in other lawsuits challenging over 300 other initial public offerings and follow-on offerings conducted in 1999 and 2000. The cases were consolidated for pretrial purposes. On February 19, 2003, the Court ruled on all defendants’ motions to dismiss. The motion was denied as to claims under the Securities Act of 1933 in the case involving us as well as in all other cases (except for 10 cases). The motion was denied as to the claim under Section 10(b) as to us, on the basis that the complaint alleged that we had made acquisition(s) following the IPO. The motion was granted as to the claim under Section 10(b), but denied as to the claim under Section 20(a), as to the remaining individual defendant.

Immersion Corporation vs. Microsoft Corporation, Sony Computer Entertainment Inc. and Sony Computer Entertainment of America, Inc.

On February 11, 2002, we filed a complaint against Microsoft Corporation, Sony Computer Entertainment, Inc., and Sony Computer Entertainment of America, Inc. in the U.S. District Court for the Northern District Court of California alleging infringement of U.S. Patent Nos. 5,889,672 and 6,275,213. The case was assigned to United States District Judge Claudia Wilken. On April 4, 2002, Sony Computer Entertainment and Microsoft answered the complaint by denying the material allegations and alleging counterclaims seeking a judicial declaration that the asserted patents were invalid, unenforceable, or not infringed. Under the counterclaims, the defendants were also seeking damages for attorneys’ fees. On October 8, 2002, we filed an amended complaint, withdrawing the claim under the U.S. Patent No. 5,889,672 and adding claims under a new patent, U.S. Patent No. 6,424,333.

On January 5 and 6, 2005, the Court held a bench trial on Sony Computer Entertainment’s remaining allegations that the ’333 patent was not enforceable due to alleged inequitable conduct. On March 24, 2005, the Court resolved this issue, entering a written order finding in favor of us. On March 24, 2005, Judge Wilken also entered judgment in our favor and awarded us $82.0 million in past damages, and pre-judgment interest in the amount of $8.7 million, for a total of $90.7 million. We were also awarded certain court costs. Court costs do not include attorneys’ fees.

Patents for which reexamination was not requested in Sony Computer Entertainment’s original requests for reexamination; we have opposed this petition. The PTO has not yet issued a decision on Sony Computer Entertainment’s third petition. Sony Computer Entertainment also filed ex parte reexamination requests on the claims of the ’333 and ’213 Patents on December 13, 2005.

On June 16, 2005, Sony Computer Entertainment filed a Notice of Appeal from the District Court Judgment to the United States Court of Appeals for the Federal Circuit. The appeals of the January and February orders regarding the compulsory license have been consolidated with this appeal of the Judgment. Sony Computer Entertainment’s Opening Brief was filed on October 21, 2005; we filed an Opposition Brief on December 5, 2005. Due to the cross appeal by ISLLC (see below), the Federal Circuit allowed us to file a Substitute Opposition Brief on February 17, 2006 responding to the briefs filed by both Sony Computer Entertainment and ISLLC. We expect the briefing for the appeal to be concluded by all parties by the end of March 2006.

Internet Services LLC Litigation

On January 12, 2005, ISLLC filed Amended Cross-Claims and Counterclaims against us that contained similar claims. ISLLC also realleged counterclaims against Sony Computer Entertainment. On January 28, 2005, we filed a motion to dismiss ISLLC’s Amended Cross-Claims and a motion to strike ISLLC’s Counterclaims against Sony Computer Entertainment. On March 24, 2005 the Court issued an order dismissing ISLLC’s claims with prejudice as to ISLLC’s claim seeking a declaratory judgment that it is an exclusive licensee under the ‘213 and ‘333 patents and as to ISLLC’s claim seeking “judicial apportionment” of the damages verdict in the Sony Computer Entertainment case. The Court’s order further dismissed ISLLC’s claims without prejudice as to ISLLC’s breach of contract and unjust enrichment claims.

Immersion Corporation vs. Electro Source LLC

On September 24, 2004, we filed in the United States District Court for the Northern District of California a complaint for patent infringement against Electro Source LLC (“Electro Source”) (Case No. 04-CV-4040 CW). Electro Source is a leading seller of video game peripherals under the Pelican Accessories brand. Our Complaint alleged that Electro Source had willfully infringed, and was continuing to willfully infringe, the same two patents asserted in our litigation against Sony Computer Entertainment. The Complaint sought injunctive relief, as well as damages in an amount to be proven at trial, trebled due to Electro Source’s willful infringement, and attorneys’ fees and costs. Electro Source filed an answer to the Complaint denying the material allegations and asserting against us counterclaims seeking a judicial declaration that the asserted patents are invalid, unenforceable, and not infringed.

On February 28, 2006, we announced that we had settled our legal differences with Electro Source and both parties agreed to dismiss all claims and counterclaims relating to this matter. In addition to the Confidential Settlement Agreement, Electro Source entered into a worldwide license to our patents for vibro-tactile devices in the consumer gaming peripheral field of use. Electro Source will make royalty payments to us based on sales by Electro Source of spinning mass vibro-tactile gamepads, steering wheels, and other game controllers for dedicated gaming consoles, such as the Sony PlayStation and PlayStation 2, the Nintendo GameCube, and the Microsoft Xbox and Xbox 360. Both companies also have agreed to explore the possibility of working together in technology or engineering related assignments. In March 2006, Electro Source paid us $650,000. We are entitled to be paid a minimum amount of $1.0 million in future periods. Both parties each assumed financial responsibility for their respective legal costs with respect to the lawsuit.


Item 4.	*Submission of Matters to a Vote of Security Holders*

No matters were submitted to a vote of security holders in the fourth quarter of fiscal 2005.

PART II


Item 5.	*Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities*

Our common stock is traded on the Nasdaq National Market under the symbol “IMMR.” The following table sets forth, for the periods indicated, the high and low sales prices for our common stock on such market.


	High		Low

Fiscal year ended December 31, 2005
Fourth Quarter	$	7.50	$	6.11
Third Quarter	$	7.13	$	5.23
Second Quarter	$	6.34	$	4.87
First Quarter	$	7.93	$	5.45
Fiscal year ended December 31, 2004
Fourth Quarter	$	7.64	$	4.36
Third Quarter	$	7.00	$	4.00
Second Quarter	$	8.35	$	3.85
First Quarter	$	10.39	$	5.61

On February 24, 2006, the closing price was $6.88 and there were 170 holders of record of our common stock. Because many of such shares are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders.

Dividend Policy

We have never declared or paid any cash dividends on our common stock and we do not anticipate paying cash dividends in the foreseeable future. We currently intend to retain any earnings to fund future growth, product development, and operations.

Item 7.	*Management’s Discussion and Analysis of Financial Condition and Results of Operations*

The following discussion should be read in conjunction with the consolidated financial statements and notes thereto.

This Management’s Discussion and Analysis of Financial Condition and Results of Operations includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. The forward-looking statements involve risks and uncertainties. Forward-looking statements are identified by words such as “anticipates,” “believes,” “expects,” “intends,” “may,” “will,” and other similar expressions. However, these words are not the only way we identify forward-looking statements. In addition, any statements, which refer to expectations, projections, or other characterizations of future events or circumstances, are forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements as a result of a number of factors, including those set forth in Item 1A,“Risk Factors,” those described elsewhere in this report, and those described in our other reports filed with the SEC. We caution you not to place undue reliance on these forward-looking statements, which speak only as of the date of this report, and we undertake no obligation to release the results of any revisions to these forward-looking statements which could occur after the filing of this report.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, bad debts, warranty obligations, patents and intangible assets, inventories, contingencies, and litigation. We base our estimates on historical experience and on various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements:

Revenue Recognition

We recognize revenues in accordance with applicable accounting standards including Staff Accounting Bulletin (“SAB”) No. 104, “Revenue Recognition,” Emerging Issues Task Force (“EITF”) Issue No. 00-21, “Accounting for Revenue Arrangements with Multiple Deliverables,” and the American Institute of Certified Public Accountants (“AICPA”) Statement of Position (“SOP”) 97-2, “Software Revenue Recognition,” as amended. Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or service has been rendered, the fee is fixed and determinable, and collectibility is probable. We derive our revenues from three principal sources: royalty and license fees, product sales, and development contracts.

Royalty and license revenue

We recognize royalty and license revenue based on royalty reports or related information received from the licensee as well as time-based licenses of our intellectual property portfolio. Up-front payments under license agreements are deferred and recognized as revenue based on either the royalty reports received or amortized over the license period depending on the nature of the agreement. Advance payments under license agreements that also require us to provide future services to the licensee are deferred and recognized over the service period when vendor-specific objective evidence (“VSOE”) related to the value of the services does not exist.

We generally recognize revenue from our licensees under one or a combination of the following license models:


License Revenue Model		Revenue Recognition

Perpetual license of intellectual property portfolio based on per unit royalties, no services contracted.		Based on royalty reports received from licensees. No further obligations to licensee exist.

Time-based license of intellectual property portfolio with up-front payments and/or annual minimum royalty requirements, no services contracted.		Based on straight-line amortization of annual minimum/up-front payment recognized over contract period or annual minimum period. No further obligations to licensee exist.

Perpetual license of intellectual property portfolio or technology license along with contract for development work.		Based on cost-to-cost percentage-of-completion accounting method over the service period. Obligation to licensee exists until development work is complete.

License of software or technology, no modification necessary, no services contracted.		Up-front revenue recognition based on SOP 97-2 criteria or EITF No. 00-21, as applicable.

Individual contracts may have characteristics that do not fall within a specific license model or may have characteristics of a combination of license models. Under those circumstances, we recognize revenue in accordance with SAB No. 104, EITF No. 00-21, and SOP 97-2, as amended, to guide the accounting treatment for each individual contract. See also comments regarding “Multiple element arrangements” below. If the information received from our licensees regarding royalties is incorrect or inaccurate, our revenues in future periods may be adversely affected. To date, none of the information we have received from our licensees has caused any material reduction in future period revenues.

Product sales

We recognize revenues from product sales when the product is shipped, provided collection is determined to be probable and no significant obligation remains. We sell the majority of our products with warranties ranging from three to twenty-four months. We record the estimated warranty costs during the quarter the revenue is recognized. Historically, warranty-related costs and related accruals have not been significant. We offer a general right of return on the MicroScribe product line for 14 days after purchase. We recognize revenue at the time of shipment of a

MicroScribe system and provide an accrual for potential returns based on historical experience. No other general right of return is offered on our products.

Development contracts and other revenue

Development contracts and other revenue is comprised of professional services (consulting services and/or development contracts), customer support, and extended warranty contracts. Development contract revenues are recognized under the cost-to-cost percentage-of-completion accounting method based on physical completion of the work to be performed. Losses on contracts are recognized when determined. Revisions in estimates are reflected in the period in which the conditions become known. Customer support and extended warranty contract revenue is recognized ratably over the contractual period.

Multiple element arrangements

We enter into revenue arrangements in which the customer purchases a combination of patent, technology, and/or software licenses, products, professional services, support, and extended warranties (multiple element arrangements). When VSOE of fair value exists for all elements, we allocate revenue to each element based on the relative fair value of each of the elements. The price charged when the element is sold separately generally determines the fair value or VSOE. For arrangements where VSOE of fair value exists only for the undelivered elements, we defer the full fair value of the undelivered elements and recognize the difference between the total arrangement fee and the amount deferred for the undelivered items as revenue, assuming all other criteria for revenue recognition have been met.

Our revenue recognition policies are significant because our revenues are a key component of our results of operations. In addition, our revenue recognition determines the timing of certain expenses, such as commissions and royalties. Revenue results are difficult to predict, and any shortfall in revenue or delay in recognizing revenue could cause our operating results to vary significantly from quarter to quarter and could result in greater or future operating losses.

Long-term Liabilities

In 2003 we executed a series of agreements with Microsoft as described in Note 9 to the consolidated financial statements that provided for settlement of our lawsuit against Microsoft as well as various licensing, sublicensing, and equity and financing arrangements. We accounted for the proceeds received under the agreements as a long-term customer advance based on certain provisions that would result in payment of funds to Microsoft. Upon Microsoft’s election to convert its shares of our Series A Redeemable Convertible Preferred Stock (“Series A Preferred Stock”) into common stock in April 2004, we reduced the long-term customer advance from Microsoft to the minimum amount we would be obligated to pay Microsoft upon a settlement with Sony Computer Entertainment. The remainder of the consideration was transferred to common stock.

In December 2004, we executed a series of agreements as described in Note 7 to the consolidated financial statements that provided for the issuance of 5% Senior Subordinated Convertible Debenture (“5% Convertible Debenture”), and warrants, and that granted certain registration rights to the holders of the 5% Convertible Debentures (“Registration Rights”). We accounted for the issuance of our 5% Convertible Debentures and related warrants in accordance with EITF No. 98-5, “Accounting for Convertible Securities with Beneficial Conversion Features or Contingently Adjustable Conversion Ratios” and other related accounting guidance. We estimated the relative fair value of the various instruments included in the agreements entered into in December 2004 and allocated the relative fair values to be as follows: warrants — $1.7 million, Put Option — $0.1 million, Registration Rights — $0.1 million, issuance costs — $1.3 million, 5% Convertible Debenture — $16.8 million. The 5% Convertible Debentures are being accreted to $20.0 million over their five-year life, resulting in additional interest expense. The value of the warrants is included in Stockholders’ Deficit, the value of the Put Option and Registration Rights are recorded as liabilities and are subject to future value adjustments, and the value of the 5% Convertible Debentures is recorded as long-term debt.

Recovery of Accounts Receivable

We maintain allowances for doubtful accounts for estimated losses resulting from our review and assessment of our customers’ ability to make required payments. If the financial condition of one or more of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances might be required. To date such estimated losses have been within our expectations.

Inventory Reserves

We reduce our inventory value for estimated obsolete and slow moving inventory in an amount equal to the difference between the cost of inventory and the net realizable value based upon assumptions about future demand and market conditions. If actual future demand and market conditions are less favorable than those projected by management, additional inventory write-downs may be required.

Product Return and Warranty Reserves

We provide for estimated costs of future anticipated product returns and warranty obligations based on historical experience when related revenues are recognized, and we defer warranty-related revenue over the related warranty term.

Intangible Assets

We have acquired patents and other intangibles. In addition, we capitalize the external legal and filing fees associated with patents and trademarks. We assess the recoverability of our intangible assets, and we must make assumptions regarding estimated future cash flows and other factors to determine the fair value of the respective assets that affect our consolidated financial statements. If these estimates or related assumptions change in the future, we may be required to record impairment charges for these assets. We amortize our intangible assets related to patents and trademarks, once they issue, over their estimated useful lives, generally 10 years. Future changes in the estimated useful life could affect the amount of future period amortization expense that we will incur. During 2005, we capitalized external costs associated with patents and trademarks of $1.0 million. Our total amortization expense for the same period for all intangible assets was $1.3 million.

The above listing is not intended to be a comprehensive list of all of our accounting policies. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP, with no need for management’s judgment in their application. There are also areas in which management’s judgment in selecting any available alternative would not produce a materially different result. See our consolidated financial statements included elsewhere in this Annual Report, which contains accounting policies and other disclosures required by GAAP.

Results of Operations

Overview of 2005

During 2005, we achieved several significant milestones including growth in several of our key market areas. This growth was due, in part, to our continued investment in a strengthened and more focused sales and marketing effort across our business segments during 2005. In addition,


	•	As market acceptance of medical simulation has increased, our medical product sales grew 29% in 2005 on a year-over-year basis and accounted for 84% of total Immersion Medical revenue for the year. This growth is also a result of the ongoing transformation of our business model into one emphasizing product development that leads to increased product sales. In 2005 we introduced significant new software modules for our endovascular training simulator.

	•	In 2005, an additional handset licensee was signed, SKY Teletech. In addition, the first Samsung mobile phones with our VibeTonz technology launched, and by the end of the year, four VibeTonz-enabled models were being offered by six wireless operators worldwide that serve a total of approximately 140 million subscribers. Content agreements were also signed with several companies.


	•	We launched our TouchSense system for touchscreens and signed an agreement with 3M Touch Systems. It is expected that 3M will integrate our components into its touchscreens and market and sell the resulting product to manufacturers of casino gaming and bar-top amusement equipment.

	•	In 2005, royalty revenue from automotive market increased 34% as more vehicles shipped with our technology, including the launch in Europe of the new Mercedes-Benz S class sedan. We also signed new license agreements with Volkswagen and automotive supplier Methode.

	•	On March 24, 2005, the U.S. District Court for the Northern District of California entered judgment in our favor and awarded us a total of $90.7 million in damages and interest with regard to our litigation with Sony Computer Entertainment. The court issued, and subsequently stayed pending appeal, a permanent injunction against the manufacture, use, sale, or import into the United States of the infringing Sony PlayStation system consisting of the PlayStation consoles, Dual Shock controllers, and the 47 games found by the jury to infringe our patents. The court further ordered Sony Computer Entertainment to pay a compulsory license fee for the duration of the stay of the permanent injunction, pursuant to which Sony Computer Entertainment has made quarterly payments to us. Sony Computer Entertainment has appealed the judgment, including the $90.7 million award, the injunction, and the compulsory license, to the United States Court of Appeals for the Federal Circuit.

In 2006, we expect to continue to focus on the execution of sales and marketing plans in our established businesses to increase revenue and make selected investments in product and technology development for longer-term new growth areas. We have taken measures to control our operating expenses including a reduction in force of approximately 10% in early 2005. We expect litigation expenses to decrease in 2006 as compared to 2005. We have budgeted to continue to protect and defend our extensive intellectual property portfolio across all business segments. Our success could be limited by several factors, including the timely release of our new products or our licensees’ products, continued market acceptance of our products and technology, the introduction of new products by existing or new competitors, and the cost of ongoing litigation. For a further discussion of these and other risk factors, see Item 1A — “Risk Factors.”

Fiscal 2005 Compared to Fiscal 2004

Total Revenue. Our total revenue for the year ended December 31, 2005 increased by $514,000 or 2% to $24.3 million from $23.8 million in 2004.

Royalty and license revenue. Royalty and license revenue is comprised of royalties earned on sales by our licensees and license fees charged for our intellectual property portfolio. Royalty and license revenue increased by $110,000 or 1% from 2004 to 2005. The increase in royalty and license revenue was primarily a result of an increase in gaming royalties of $678,000 and an increase in automotive royalties and licensee revenue of $399,000, offset by a decrease in medical royalty and license revenue of $1.1 million. The increase in gaming royalties was mainly due to increased third-party market share of aftermarket game console controllers, increased growth in the game console controller market, and royalties from new licensees signed in late 2004 and early 2005. In the console peripheral business, many of our third-party licensees from whom we earn per unit royalties enjoyed the benefits of strong sales of premium products and significant market share growth in 2005 at the expense of first-party peripheral

makers (i.e., Sony, Microsoft, and Nintendo). Third-party peripheral makers’ market share tends to increase as consoles near end of life. Microsoft’s Xbox 360 next-generation video console system was introduced in November 2005, and additional next-generation consoles are expected to be introduced in late 2006 by Sony and Nintendo. Accordingly, we anticipate that third-party royalties will likely decline as these new consoles are introduced and market share shifts back to first-party peripheral makers. For the Xbox 360 next-generation video console system, Microsoft has, to date, not licensed the rights to produce wireless controllers to any third party peripheral makers. Wireless game controllers account for a significant and growing portion of all game controller sales. Therefore, by retaining the market for wireless Xbox 360 game controllers exclusively for itself, Microsoft will likely significantly increase its market share of all aftermarket game controller sales, the effect of which is likely to reduce our gaming royalty revenue. Furthermore, according to NPD Funworld, in the first two months of launch of the Xbox 360, Microsoft had over a 90% market share of wired Xbox 360 game controllers, leaving third parties with less than a 10% market share. While we expect third party market share of wired Xbox 360 game controllers to increase in 2006 from its current level, the dominant market position by Microsoft in wired Xbox 360 game controllers will reduce our gaming royalty revenue compared to 2005. In the PC gaming peripheral business, the overall industry again declined, but this decline was more than offset by the aforementioned gains in the console peripheral business. Automotive royalties increased in 2005 due to increased licensee revenue from signing a new licensee in 2005 and royalties from an increased number of vehicles manufactured with our technology incorporated in them. We expect increased automotive royalties and license revenue in 2006 based on new licensees signed and additional launches of cars sold incorporating our technology. The decrease in medical royalty and license revenue in 2005 compared to 2004 was primarily due to a decrease in license revenue from our license and development agreements with Medtronic. Revenue recognition on the license and development agreements with Medtronic is based on cost-to-cost percentage-of-completion; a decrease in activity on these contracts results in a decrease in revenue recognized.

Product sales. Product sales increased by $1.1 million or 10% from 2004 to 2005. The increase in product sales was primarily due to increased medical product sales of $1.8 million, in particular, increased sales of our vascular access, endovascular, and laparoscopic simulator platforms. This increase was a result of focusing sales force resources on selling training simulator products to hospitals and teaching institutions as well as targeted marketing programs and improved reseller performance. Additionally, as the market acceptance of medical simulation has increased, we have transformed our business model for Immersion Medical into one that emphasizes product development and product sales as opposed to development contracts. Offsetting this was a decrease of $703,000 in product sales mainly from our 3D and professional products, and microprocessors. This decrease was primarily due to reduced sales of our 3D products such as our CyberGlove^® and CyberTouch^tm devices caused by the delay in upgrades to this product line and increased competition, decreased sales of our force feedback electronics for arcade gaming due to the timing of product introductions by our customers, and reduced sales of microprocessors based on a decision to eliminate the sales effort related to this lower margin product line.

Development contracts and other revenue. Development contracts and other revenue decreased by $714,000 or 21% from 2004 to 2005. Development contracts and other revenue is comprised of revenue on commercial and government contracts. The decrease in this category was primarily due to decreases in both medical government and commercial development contract revenues, but was partially offset by an increase in development contracts in the industrial market. The decrease in medical development contract revenue was due to a decrease in revenue recognized on our license and development agreements with Medtronic and the continued transition of our medical engineering resources from government grants and certain commercial development contract efforts to product development efforts that focus on leveraging our existing sales and channel distribution capabilities.

Fiscal 2004 Compared to Fiscal 2003

Total Revenue. Our total revenues for the year ended December 31, 2004 increased by $3.6 million or 18% to $23.8 million from $20.2 million in 2003.

Royalty and license revenue. Royalty and license revenue increased by $2.7 million or 44% from 2003 to 2004. The increase in royalty and license revenue was primarily a result of an increase in gaming royalties of $2.5 million and an increase in automotive royalties of $337,000, offset by a decrease in medical royalty and license fees of $150,000. The increase in gaming royalties was mainly due to increased third-party market share of

aftermarket game console controllers, increased growth in the game console controller market, the addition of new licensees, and increased PC gaming royalties due to Microsoft’s exit from the PC gaming peripheral business. Automotive royalties increased in 2004 due to an increase in the number of vehicles manufactured with our technology incorporated in them. The decrease in medical royalty and license revenue in 2004 compared to 2003 was primarily due to a decrease in license revenue from our license and development agreements with Medtronic. Although total revenue from Medtronic increased in 2004, license revenue decreased due to a change in the mix of revenue from Medtronic in 2004.

Product sales. Product sales increased by $2.2 million or 23% from 2003 to 2004. The increase in product sales was primarily due to increased medical product sales of $1.8 million, mainly due to increased sales of our endovascular and laparoscopic simulator platforms as a result of new and focused sales force management and the timing of purchases from significant customers. Product sales from 3D and professional products increased in 2004 by $294,000, primarily due to increased sales of our force feedback electronics for arcade gaming as a result of a customer’s successful product introduction that began in the third quarter of 2003, and increased sales of our SoftMouse product.

Development contracts and other revenue. Development contracts and other revenue decreased by $1.3 million or 29% from 2003 to 2004. The decrease in this category was primarily attributable to a decrease of $1.2 million in government contracts. The decrease in revenue from government contracts was due to a reduced number of government grants awarded as well as a decrease in the work performed against our current government contracts. In 2004, Immersion Medical began its transition from government grants and certain commercial development contract efforts to product development efforts thereby reducing revenue in this category.

Cost of Product Sales


	2005			% Change			2004			% Change			2003

Cost of product sales	$	6,446			3	%	$	6,255			19	%	$	5,276
% of product sales		51	%					54	%					56	%

Our cost of product sales consists primarily of materials, labor, and overhead. There is no cost of product sales associated with royalty and license revenue or development contract revenue. The cost of product sales increased by $191,000 or 3% from 2004 to 2005. This increase was mainly due to increased product sales of 10% and the corresponding increased direct materials, freight costs to customers, and royalties, as well as increased inventory write offs, offset in part by decreased overhead and decreased price and cost variances. Increased volume related expense such as increased direct materials, increased freight costs, and increased royalties accounted for $130,000 of the increase in cost of product sales from 2004 to 2005. Of the aforementioned amount, direct materials only increased by $22,000 due to favorable product mix shifts resulting from increased sales of higher margin products such as our vascular access training simulators and reduced sales of our lower margin microprocessors. Additionally during 2005, we experienced increased physical inventory write offs, scrap charges, and increased reserves for excess and obsolete inventory of $173,000 due to some product and process transitions during the period. These increases were offset in part by reduced overhead costs and reduced price and cost variances of $112,000. Cost of product sales as percentage of revenue declined to 51% in 2005 as compared to 54% in 2004 due to the aforementioned favorable product mix shifts.

The cost of product sales increased by $1.0 million or 19% from 2003 to 2004. The increase was primarily a combination of increased direct material and labor costs of $1.2 million, associated with increased product sales of 23% and increased price and cost variances of $165,000, offset in part by decreased inventory write offs for excess and obsolete inventory of $136,000, due to revisions made to certain products to improve quality in 2003, decreased warranty costs of $105,000, and decreased royalty costs of $53,000.

Sales and Marketing. Our sales and marketing expenses are comprised primarily of employee compensation and benefits, advertising, trade shows, brochures, market development funds, travel, and an allocation of facilities costs. Sales and marketing expenses increased by $337,000 or 3% in 2005 compared to 2004. The increase was primarily the result of increased travel of $369,000, an increase in bad debt expense of $232,000, and an increase in office expenses of $148,000 resulting from the ongoing execution of sales and marketing plans in our established businesses. These increases were offset by cost savings from a reduction in professional and consulting fees of $309,000 due to reduced employee recruitment fees, and a reduction in market research expense of $115,000. We expect to continue to focus our sales and marketing efforts on medical, mobile phone, and touchscreen market opportunities to build greater market acceptance for our touch technologies. We anticipate sales and marketing costs will increase in absolute dollars in future periods as we increase our investment to exploit market opportunities for our technologies.

Sales and marketing expenses increased by $3.5 million or 46% in 2004 compared to 2003. The increase in expenses was primarily due to the expansion of our sales and marketing team, investment in initiatives focusing on medical and mobile phone market opportunities, and the upgrading of our corporate marketing function. The increase in 2004 included increased headcount and related compensation, benefits, and overhead of $2.3 million, increased travel of $300,000 to support sales and marketing efforts, an increase in advertising and marketing expenses including, market research, product marketing, and shows and exhibits of $457,000, an increase in bad debt expense of $156,000 primarily due to reversals in 2003, and an increase in consulting, recruiting, and license fees of $283,000.

Research and Development. Our research and development expenses are comprised primarily of employee compensation and benefits, consulting fees, tooling and supplies, and an allocation of facilities costs. Research and development expenses decreased by $2.0 million or 25% in 2005 compared to 2004. The decrease was mainly due to an increased focus on targeted development work, leading to a reduction in general development contract work, which led to a reduction in headcount and related compensation, benefits, overhead, and travel, totaling $1.5 million, a decrease in consulting expense of $243,000, a reduction in supplies and materials and prototyping expenses of $162,000, and a decrease in demonstration unit expenses of $85,000. We believe that continued investment in research and development is critical to our future success, and we expect to make targeted investments in areas of product and technology development to support future growth.

Research and development expenses increased by $86,000 or 1% in 2004 compared to 2003. The increase was mainly due to an increase in supplies and materials and prototyping expenses of $256,000, an increase in outside professional services of $240,000 to supplement our engineering staff, and an increase of travel of $58,000, partially offset by a decrease in compensation, benefits, and overhead of $470,000 mainly due to a decrease in deferred stock compensation expense from 2003 to 2004.

General and Administrative. Our general and administrative expenses are comprised primarily of employee compensation and benefits, legal and professional fees, office supplies, travel, and an allocation of facilities costs. General and administrative expenses decreased by $6.5 million or 38% in 2005 compared to 2004. The decrease was primarily attributable to a decrease in legal and professional fees of $6.6 million, mostly related to the litigation against Sony Computer Entertainment. The decrease was partially offset by an increase in supplies and office expense of $91,000. Although we expect our total litigation costs to decrease in 2006 as compared to 2005, we expect that the dollar amount of general and administrative expenses to be a significant component of our operating expenses. We will continue to incur litigation costs, including costs associated with the appeal and other motions that Sony Computer Entertainment has made, and we expect will continue to make, and costs related to litigation

against other parties as we defend our intellectual property. In addition, we anticipate costs associated with maintaining compliance with the Sarbanes-Oxley Act of 2002 and Nasdaq listing requirements will continue to be significant.

General and administrative expenses increased by $4.6 million or 37% in 2004 compared to 2003. The increase was primarily attributable to increased legal and professional fees of $4.2 million, mostly related to the litigation against Sony Computer Entertainment and compliance with the Sarbanes Oxley Act of 2002, and increased compensation, benefits, and overhead costs of $355,000.

Amortization of Intangibles. Our amortization of intangibles is comprised primarily of patent amortization and other intangible amortization. Amortization of intangibles decreased by $214,000 or 15% from 2004 to 2005. Amortization of intangibles decreased by $149,000 or 9% from 2003 to 2004. The decreases were primarily attributable to some intangible assets reaching full amortization.

Restructuring Costs. Restructuring costs were $185,000 for 2005. No restructuring costs were incurred in 2004 or 2003. The costs consisted of severance benefits paid as a result of our reduction in force in the first quarter of 2005. Employees from manufacturing, sales and marketing, research and development, and general and administrative were included in the reduction in force. We did not incur any additional charges related to this reduction in force and do not anticipate any further costs in future periods related to this reduction in force.

Interest and Other


	2005		% Change			2004		% Change			2003

Interest and other income	$	490		192	%	$	168		33	%	$	126
Interest expense		1,506		3,573	%		41		(18	)%		50
Other expense		11		(98	)%		624		(70	)%		2,046

Interest and Other Income. Interest and other income consists primarily of interest income and dividend income from cash and cash equivalents. Interest and other income increased by $322,000 from 2004 to 2005 as a result of higher interest rates and increased cash and cash equivalents primarily due to the $20.0 million we received in December 2004 from the sale of our 5% Convertible Debentures. Interest earned on monies received pursuant to the Sony Computer Entertainment compulsory license has not been recorded as interest income but has been recorded as long-term deferred revenue due to the contingent nature of these payments.

Interest and other income increased by $42,000 from 2003 to 2004. The increase was mainly attributable to the $26.0 million received during the third quarter of 2003 from Microsoft for a license to our portfolio of patents and their investment in our Series A Preferred Stock.

Interest Expense. Interest expense consists primarily of interest expense on notes payable, capital leases, and our 5% Convertible Debenture. The increase in interest expense of $1.5 million from 2004 to 2005 was primarily due to interest and accretion expense on our 5% Convertible Debentures. The decrease in interest expense of $9,000 from 2003 to 2004 related to the maturity and subsequent payment of certain notes payable in 2004, partially offset by interest and accretion expense on our 5% Convertible Debentures. We expect interest expense to continue to be significant while our 5% Convertible Debentures remain outstanding.

Other Expense. Other expense consists primarily of impairment losses on our investments in privately held companies and accretion and dividend expense on our long-term customer advance from Microsoft. Other expense was $11,000 in 2005, $624,000 in 2004, and $2.0 million in 2003. Other expense in 2004 consisted primarily of accretion of $500,000 on our long-term customer advance from Microsoft and dividend expense on our Series A Preferred Stock of $98,000. Other expense in 2003 consisted primarily of a noncash impairment loss due to the write off of our investment in a technology application developer, There, Inc., in the amount of $1.0 million. We review our cost-method investments on a quarterly basis to determine if there has been an other-than-temporary decline in the investment’s value based on our estimate of their net realizable value taking into account the companies’ respective business prospects, financial condition, and ability to raise third-party financing. The impairment loss was based on There, Inc.’s continued decline in financial condition, uncertain future revenue streams, and inability to raise adequate third-party financing. In addition to the impairment loss, other expense for 2003 included

accretion $867,000 on our long-term customer advance from Microsoft and dividend expense on our Series A Preferred Stock of $183,000.

Provision for Taxes

Benefit (provision) for income taxes	$	(158	)		N/A	$	151		N/A	$	(154	)

Benefit (Provision) for Income Taxes. For the year ended 2005, we recorded a provision for income taxes of $158,000, yielding an effective tax rate of (1.2%). The provision for income tax was based on federal and state alternative minimum income tax payable on taxable income and foreign withholding tax expense. Although we incurred a pre-tax loss of $12.9 million, sums received from Sony Computer Entertainment and interest thereon included in long-term deferred revenue, approximating $16.8 million in 2005, are taxable, thus giving rise to an overall taxable profit. The effective tax rate differs from the statutory rate primarily due to the recording of a full valuation allowance of $44.7 million against deferred tax assets. For the year ended 2004, we reversed the tax provision that had been recorded in 2003. No tax provision was required for the years ended December 31, 2004 and 2003 due to net losses in those periods. For the year ended 2003, we had recorded a provision for income taxes of $154,000 on a pre-tax loss of $16.8 million, yielding an effective tax rate of (0.9%). The 2003 provision for income tax was based on federal alternative minimum income tax due on taxable income primarily the result of the $20.0 million license fee paid by Microsoft during 2003. This rate differed from the statutory rate primarily due to the recording of a full valuation allowance of $31.3 million against deferred tax assets. Subsequent to December 31, 2003, in May 2004, Revenue Procedure 2004-34 (“Rev. Proc. 2004-34”) was issued by the Internal Revenue Service. This revenue procedure allows taxpayers a limited deferral beyond the taxable year of receipt for certain advance payments. Qualifying taxpayers generally may defer to the next succeeding year the inclusion in gross income for federal income tax purposes of advance payments to the extent the advance payments are not recognized (or, in certain cases, are not earned) in the taxable year of receipt. Under Rev. Proc. 2004-34 we were able to defer a significant amount of the Microsoft payment during 2003 when calculating our federal taxable income and therefore were not subject to federal alternative minimum income tax for the year ended December 31, 2003.

Segment Results for the Years Ended December 31, 2005, 2004, and 2003 are as follows:

We have two operating and reportable segments. One segment, Immersion Computing, Entertainment, and Industrial, develops and markets touch feedback technologies that enable software and hardware developers to enhance realism and usability for their computing, entertainment, and industrial applications. The second segment, Immersion Medical, develops, manufactures, and markets medical simulators that recreate realistic healthcare environments.

Fiscal 2005 Compared to Fiscal 2004

Immersion Computing, Entertainment, and Industrial segment. Revenues from the Immersion Computing, Entertainment, and Industrial segment increased $868,000, or 6% for the year ended December 31, 2005 compared to the year ended December 31, 2004. The increase was primarily attributable to increased royalty and license revenue of $1.2 million from our licensees that sell console and PC gaming peripheral products, as well as increased royalties and license fees from our automotive licensees, and increased development contract revenue of $270,000, primarily in the industrial market, offset in part by a reduction in product sales of $609,000, primarily due to decreased sales of our 3D products and lower sales of microprocessors. Our net loss for 2005 decreased by $7.5 million or 42% as compared to 2004. The decrease was primarily due to reduced operating expenses of $7.2 million, mainly due to reduced litigation costs associated with our litigation against Sony Computer Entertainment and increased gross margin of $1.2 million, primarily due to increased revenue and higher margin royalty and license revenues accounting for a larger percentage of the revenue mix, offset in part by increased non-operating expenses of $864,000, mainly due to increased interest expense on our 5% Convertible Debentures. Although we expect our total litigation costs to decrease in 2006 as compared to 2005, we will continue to incur litigation costs, including costs associated with the appeal and other motions that Sony Computer Entertainment has made, and we expect will continue to make, and costs related to litigation against other parties as we defend our intellectual property. In addition, we anticipate costs associated with maintaining compliance with the Sarbanes-Oxley Act of 2002 and Nasdaq listing requirements will continue to be significant. Also, we anticipate sales and marketing costs in this segment will increase in absolute dollars in future periods as we increase our investment in the mobile phone, touchscreen, and other markets to exploit opportunities for our technologies.

Immersion Medical segment. Revenues from Immersion Medical decreased $206,000, or 2% from 2004 to 2005. The decrease was due primarily to a decrease of $1.1 million in royalty and license revenue, and a decrease of $930,000 in development contract revenue, offset in part by an increase of $1.8 million in product sales primarily due to increased sales of our vascular access, endovascular, and laparoscopic simulator platforms. Royalty and license revenue and development contract revenue decreased primarily due to a reduction in revenue recognized on our license and development agreements with Medtronic. Decreased work performed on government contracts also contributed to the decrease in development contract revenue. The product sales increase was a result of focusing sales force resources on selling training simulator products to hospitals and teaching institutions as well as targeted marketing programs and improved reseller performance. In an effort to increase product sales, we continue to transition medical engineering resources away from government grants and certain commercial development contract efforts to focus on product development to leverage existing sales and channel distribution capabilities. Our net loss for 2005 was $2.8 million, a decrease of $107,000 from the net loss of $2.9 million for 2004. The decrease in net loss was mainly due to decreased operating expenses of $936,000, primarily the result of reduced research and development spending due to the transition from development contract efforts to product sales, offset in part by decreased gross margin of $855,000 due to a change in revenue mix, including the reduction of higher margin license and development contract revenue.

Fiscal 2004 Compared to Fiscal 2003

Immersion Computing, Entertainment, and Industrial segment. Revenues from the Immersion Computing, Entertainment, and Industrial segment increased $2.1 million, or 18% for 2004 compared to 2003. The increase was mainly due to increased royalty and license revenue of $2.8 million, primarily from existing and new gaming licensees who increased their market share of the game console controllers aftermarket as well as growth in the game console controller market, offset in part by decreased product sales of $491,000 and decreased development contract revenue of $232,000, due to decreased intercompany sales and intercompany development work for Immersion Medical. Our net loss for 2004 increased by $705,000 or 4% as compared to 2003. The increase was primarily attributable to increased general and administrative expense of $3.7 million and increased sales and marketing expense of $1.8 million, offset in part by increased gross margin of $2.9 million, a decrease in other expense of $1.5 million, a decrease in amortization of intangibles of $149,000, and increased interest and other income of $60,000. The increase in gross margin was mainly due to the increase in revenue. Increased general and administrative costs were primarily related to the litigation against Sony Computer Entertainment. Increased sales and marketing expense was due primarily to our expansion of our sales and marketing team including better

worldwide geographical sales coverage and investment in mobile phone market opportunities. Other expense lessened due to a decrease in noncash impairment loss from the write off of a cost-method investment in 2003, decreased accretion of our long-term customer advance from Microsoft, and decreased dividend expense on Series A Preferred Stock.

Immersion Medical segment. Revenues from Immersion Medical increased $391,000, or 4% for 2004 compared to 2003. The increase was due to a $1.8 million increase in product sales, offset in part by a decrease in development contract revenues of $1.2 million, and a decrease in royalty and licensing revenue of $150,000. The increase in the product sales was primarily due to increased sales of our endovascular and laparoscopic simulator platforms as a result of new and focused sales force management and the timing of purchases from significant customers. In 2004, Immersion Medical began its transition from government grants and certain commercial development contract efforts to product development efforts thereby reducing revenue in development contracts. Our net loss for 2004 was $2.9 million, a change of $3.0 million from the net income of $101,000 for 2003. The net loss for 2004 was mainly the result of increased sales and marketing expenses of $1.7 million, increased general and administrative costs of $906,000, and decreased gross margin of $469,000. The increase in sales and marketing expense was primarily due to the expansion of our sales and marketing team. General and administrative expenses increased due to increased compensation and benefits expense and additional professional and outside service expenses. The decrease in gross margin was mainly due to the change in revenue mix from higher margin development contract revenue to product sales.

Liquidity and Capital Resources

Our cash, cash equivalents, and short-term investments consist primarily of money market funds and highly liquid debt instruments. All of our cash equivalents and short-term investments are classified as available-for-sale under the provisions of SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities.” The securities are stated at market value, with unrealized gains and losses reported as a component of accumulated other comprehensive income (loss), within stockholders’ deficit.

At December 31, 2005, our cash and cash equivalents totaled $28.2 million, up $2.7 million from $25.5 million at December 31, 2004.

During 2003, we entered into a series of agreements with Microsoft in connection with the settling of our lawsuit against Microsoft. As part of these agreements, we may require Microsoft, at our discretion, to buy up to $6.0 million of our 7% Senior Redeemable Convertible Debentures (“7% Debentures”), at a rate of $2.0 million per annum plus any amounts not purchased in the prior 12 months, for the two years ending July 2007. As of December 31, 2005, we had not sold any of these 7% Debentures to Microsoft.

In December 2004, we issued an aggregate principal amount of $20.0 million of 5% Convertible Debentures. The 5% Convertible Debentures will mature on December 22, 2009. The amount payable at maturity of each 5% Convertible Debenture is the initial principal plus all accrued but unpaid interest thereon, to the extent such principal amount and interest has not been converted into common shares or previously paid in cash. Commencing on the date the 5% Convertible Debentures were issued, interest accrues daily on the principal amount of the 5% Convertible Debenture at a rate of 5% per year. Interest will cease to accrue on that portion of the 5% Convertible Debenture that is converted or paid, including pursuant to conversion right or redemption. The holder of a 5% Convertible Debenture has the right to convert the outstanding principal amount and accrued and unpaid interest in whole or in part into shares of our common shares at a price of $7.0265 per common share.

Net cash provided by operating activities during 2005 was $2.2 million, a change of $17.8 million from the $15.6 million used during 2004. Cash provided by operations during the year ended December 31, 2005 was primarily the result of a $15.5 million increase due to a change in deferred revenue and customer advances primarily related to compulsory license fee payments received and interest thereon from Sony Computer Entertainment of $16.8 million and noncash charges and credits of $2.5 million, including $1.3 million in amortization of intangibles, $730,000 in depreciation, and $634,000 in accretion expenses on our 5% Convertible Debenture. Additionally, cash provided by operations during 2005 was also impacted by an increase of $791,000 due to a change in accounts receivable and an increase of $149,000 due to a change in prepaid expenses and other current assets. These increases were offset by our $13.1 million net loss, a decrease of $2.1 million due to a change in accounts payable due to the

timing of payments to vendors, a decrease of $814,000 due to a change in inventories, and a decrease of $709,000 due to a change in accrued compensation and other current liabilities. Net cash used in operating activities during 2004 was $15.6 million, a change of $3.0 million from the $12.6 million used during 2003. Cash used in operations during the year ended December 31, 2004 was comprised primarily of our $20.7 million net loss offset by noncash charges and credits of $3.1 million, including $1.6 million in amortization of intangibles and deferred stock compensation, $874,000 in depreciation, and $598,000 in dividend and accretion expenses on our Series A Preferred Stock. Cash used in operations during 2004 was also impacted by a decrease of $500,000 due to a change in accounts receivable and a decrease of $154,000 due to a change in prepaid expenses and other current assets. These decreases were offset by an increase of $1.2 million due to a change in deferred revenue and customer advances, mainly due to extending a prepayment arrangement with a licensee, an increase of $805,000 due to a change in accounts payable due to the timing of payments to vendors, an increase of $432,000 due to a change in accrued compensation and other current liabilities, and an increase of $293,000 due to a change in inventories.

Net cash used in investing activities during 2005 was $2.0 million, compared to $2.5 million used in investing activities during 2004, a change of $554,000. Net cash used in investing activities during 2005 consisted of a $1.0 million increase in other assets, primarily due to capitalization of external patent filing and application costs, and $967,000 used to purchase capital equipment. Net cash used in investing activities during 2004 was $2.5 million, compared to the $2.0 million used in investing activities during 2003, a change of $527,000. Net cash used in investing activities during 2004 consisted of a $1.9 million increase in other assets, primarily due to capitalization of external patent filing and application costs, and $623,000 used to purchase capital equipment.

Net cash provided by financing activities during 2005 was $2.2 million compared to $21.4 million provided during 2004, or a $19.2 million change from the prior year. Net cash provided by financing activities during 2005 consisted primarily of issuances of common stock and exercises of stock options in the amount of $2.2 million. Net cash provided by financing activities during 2004 consisted of the issuance of $20.0 million of our 5% Convertible Debentures as discussed in Note 7 to the consolidated financial statements and issuances of common stock and exercises of stock options in the amount of $1.8 million, offset by the payment of dividends on Series A Preferred Stock of $281,000 as discussed in Note 9 to the consolidated financial statements.

We believe that our cash and cash equivalents will be sufficient to meet our working capital needs and our continued litigation costs for at least the next twelve months. We have taken measures to control our costs and will continue to monitor these efforts. Although we will continue to incur significant additional expenses associated with post-judgment motions and an appeal process related to our litigation against Sony Computer Entertainment, we expect our litigation costs to decrease during 2006 compared to 2005. We anticipate that capital expenditures for the year ended December 31, 2006 will total approximately $1.0 million in connection with anticipated upgrades to operations and infrastructure. If we are unable to collect on the damages awarded in the Sony Computer Entertainment litigation, or have to repay the compulsory license payments previously received and interest thereon totaling $16.8 million as of December 31, 2005, or are unsuccessful in resolving the Sony Computer Entertainment litigation in the short term, we may elect to raise additional capital through sale of debt and/or equity securities or through a line of credit. Additionally, if we acquire one or more businesses, patents, or products, our cash or capital requirements could increase substantially. In the event of such an acquisition, or should any unanticipated circumstances arise that significantly increase our capital requirements, we may elect to raise additional capital through debt or equity financing. This could result in substantial dilution to our stockholders. Although we expect to be able to raise additional capital if necessary, there is no assurance that such additional capital will be available on terms acceptable to us, if at all.

Our 5% Convertible Debentures accrue interest at 5% per annum. Accordingly, we are required to make interest payments in the amount of $1.0 million per annum until such time as the 5% Convertible Debentures are either converted to common stock or mature. If the daily volume-weighted average price of our common shares is at or above 200% of the Conversion Price for at least 20 consecutive trading days, and certain other conditions are met, we have the right to (i) require the holder of a 5% Convertible Debenture to convert the 5% Convertible Debenture in whole, including interest, into shares of our common stock at a price of $7.0265 per common share, as may be adjusted under the debenture, as set forth and subject to the conditions in the 5% Convertible Debenture, or (ii) redeem the 5% Convertible Debenture. If we make either of the foregoing elections with respect to any 5% Convertible Debenture, we must make the same election with respect to all 5% Convertible Debentures.

Total contractual cash obligations	$	27,830	$	1,975	$	3,855	$	22,000

In connection with our series of agreements with Microsoft executed in July 2003, we are obligated to pay Microsoft certain amounts based on a settlement of the Sony Computer Entertainment litigation (see Notes 9 and 18 to the consolidated financial statements).

With regard to our 5% Convertible Debentures, in the event of a change of control of us, a holder may require us to redeem all or a portion of their 5% Convertible Debenture (“Put Option”). The redeemed portion shall be redeemed at a price equal to the redeemed amount multiplied by (a) 105% of the principal amount of the 5% Convertible Debenture if the change of control occurs after December 23, 2005 and on or prior to December 23, 2006, or (b) 100% of the principal amount of the 5% Convertible Debenture if the change of control occurs after December 23, 2006. The conversion price will be reduced in certain instances where shares of common stock are sold or deemed to be sold at a price less than the applicable conversion price, including the issuance of certain options, the issuance of convertible securities, or the change in exercise price or rate of conversion for options or convertible securities. The conversion price will be proportionately adjusted if we subdivide (by stock split, stock dividend, recapitalization, or otherwise) or combine (by combination, reverse stock split, or otherwise) one or more classes of our common stock. So long as any 5% Convertible Debentures are outstanding, we will not, nor will we permit any of our subsidiaries to, directly or indirectly, incur or guarantee, assume or suffer to exist any indebtedness other than permitted indebtedness under the 5% Convertible Debenture agreement. If an event of default occurs, and is continuing with respect to any of our 5% Convertible Debentures, the holder may, at its option, require us to redeem all or a portion of the 5% Convertible Debenture.

Recent Accounting Pronouncements

We have accounted for stock-based compensation awards issued to employees using the intrinsic value measurement provisions of Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”). Accordingly, no compensation expense was recorded for stock options granted with exercise prices greater than or equal to the fair value of the underlying common stock at the option grant date. In December 2004, the FASB issued SFAS No. 123R, “Share-Based Payment.” SFAS No. 123R eliminates the alternative of applying the intrinsic value measurement provisions of APB 25 to stock compensation awards issued to employees. Rather, the new standard requires enterprises to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost will be recognized over the period during which an employee is required to provide services in exchange for the award, known as the requisite service period (usually the vesting period). In March 2005, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 107 (“SAB 107”) relating to the adoption of SFAS No. 123R. SFAS No. 123R will be effective for our first quarter of fiscal 2006. We expect that the new standard will result in significant stock-based compensation expense.

The pro forma effects on net income and earnings per share, as if we had applied the fair value recognition provisions of original SFAS No. 123 on stock compensation awards (rather than applying the intrinsic value measurement provisions of APB 25), are disclosed in Note 1 to the consolidated financial statements. Although such pro forma effects of applying the original SFAS No. 123 may be indicative of the effects of adopting SFAS No. 123R, the provisions of these two statements differ in some important aspects. The actual effects of adopting SFAS No. 123R will be dependent on numerous factors including, but not limited to, the valuation model chosen by us to value stock-based awards; the assumed award forfeiture rate; the accounting policies adopted concerning the method of recognizing the fair value of awards over the requisite service period; and the transition

method. We plan to use the modified prospective application method upon our adoption of SFAS No. 123R. Accordingly, SFAS No. 123R will be applied to new awards and to awards modified, repurchased, or cancelled after the effective date. The compensation cost for the portion of awards for which the requisite service has not been rendered, (such as unvested options) that are outstanding as of the date of adoption, is recognized as the remaining requisite services are rendered. The compensation cost relating to unvested awards at the date of adoption is based on the grant-date fair value of those awards as calculated for pro forma disclosures under the original SFAS No. 123 as adjusted for the effect of estimated forfeiture rates.


Item 7A.	*Quantitative and Qualitative Disclosures About Market Risk*

We have limited exposure to financial market risks, including changes in interest rates. The fair value of our investment portfolio or related income would not be significantly impacted by a 100 basis point increase or decrease in interest rates due mainly to the short-term nature of the major portion of our investment portfolio. An increase or decrease in interest rates would not significantly increase or decrease interest expense on debt obligations due to the fixed nature of our debt obligations. Our foreign operations are limited in scope and thus we are not materially exposed to foreign currency fluctuations.

As of December 31, 2005, we had outstanding $20.0 million of fixed rate long-term convertible debentures. The holder of a 5% Convertible Debenture has the right to convert the outstanding principal amount and accrued and unpaid interest in whole or in part into our common shares at a price of $7.0265 per common share, the Conversion Price. In the event of a change of control, a holder may require us to redeem all or a portion of their 5% Convertible Debenture. This is referred to as the Put Option. The redeemed portion shall be redeemed at a price equal to the redeemed amount multiplied by (a) 105% of the principal amount of the 5% Convertible Debenture if the change of control occurs after December 23, 2005 and on or prior to December 23, 2006, or (b) 100% of the principal amount of the 5% Convertible Debenture if the change of control occurs after December 23, 2006. If the daily volume-weighted average price of our common shares is at or above 200% of the Conversion Price for at least 20 consecutive trading days and certain other conditions are met, we have the right to (i) require the holder of a 5% Convertible Debenture to convert the debenture in whole, including interest, into shares of our common stock at a price of $7.0265 per common share, as may be adjusted under the debenture, as set forth and subject to the conditions in the 5% Convertible Debenture, or (ii) redeem the 5% Convertible Debenture. If we make either of the

foregoing elections with respect to any 5% Convertible Debenture, we must make the same election with respect to all 5% Convertible Debentures.

We have equity investments in several privately held companies. We intend to hold our equity investments for the long term and will monitor whether there has been other-than-temporary declines in their values based on management’s estimates of their net realizable value taking into account the companies respective financial condition and ability to raise third-party financing. If the decline in fair value is determined to be other-than-temporary, an impairment loss is recorded and the individual security is written down to a new cost basis. As a result of our review of the fair value of these investments, we recorded an impairment loss of $1.0 million in the fourth quarter of 2003. The remaining cost basis of these investments on our Consolidated Balance Sheet is zero. As of December 31, 2005, management determined that the carrying value of these investments at zero is appropriate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years Ended December 31, 2005, 2004, and 2003


1.	Significant Accounting Policies

Description of Business — Immersion Corporation (the “Company”) was incorporated in May 1993 in California and reincorporated in Delaware in 1999 and develops, manufactures, licenses, and supports a wide range of hardware and software technologies and products that enhance users’ interaction with digital devices using their sense of touch.

Principles of Consolidation and Basis of Presentation — The consolidated financial statements include the accounts of Immersion Corporation and its majority-owned subsidiaries. All intercompany accounts, transactions and balances have been eliminated in consolidation. The Company has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America.

Reclassifications — Certain reclassifications have been made to prior year balances in order to conform to the current year presentation. These reclassifications had no effect on net loss or stockholders’ equity (deficit).

Cash Equivalents — The Company considers all highly liquid debt instruments purchased with an original or remaining maturity of less than three months at the date of purchase to be cash equivalents.

Allowance for Doubtful Accounts — The Company maintains an allowance for doubtful accounts for estimated losses resulting from its review and assessment of its customers’ ability to make required payments. The Company reviews its trade receivables by aging categories to identify significant customers with known disputes or collection issues. For accounts not specifically identified the Company provides reserves based on historical levels of credit losses and reserves.

Inventories — Inventories are stated at the lower of cost (principally on a standard cost basis which approximates FIFO) or market. The Company reduces its inventory value for estimated obsolete and slow moving inventory in an amount equal to the difference between the cost of inventory and the net realizable value based upon assumptions about future demand and market conditions.

Property and Equipment — Property is stated at cost and is generally depreciated using the straight-line method over the estimated useful life of the related asset. The estimated useful lives are as follows:


Computer equipment and purchased software			3 years
Machinery and equipment			3-5 years
Furniture and fixtures			5-7 years

Leasehold improvements are amortized over the shorter of the lease term or their useful life.

Intangible Assets — The Company accounts for its intangible assets in accordance with SFAS No. 142, “Goodwill and Other Intangible Assets.” SFAS No. 142 addresses the initial recognition and measurement of intangible assets acquired outside of a business combination and the accounting for goodwill and other intangible assets subsequent to their acquisition. SFAS No. 142 provides that intangible assets with finite useful lives will be amortized and that goodwill and intangible assets with indefinite lives will not be amortized but rather will be tested at least annually for impairment.

In addition to purchased intangible assets the Company capitalizes the external legal and filing fees associated with its patents and trademarks. These costs are amortized once the patent or trademark is issued.

For intangibles with definite useful lives, amortization is recorded utilizing the straight-line method, which approximates the pattern of consumption over the estimated useful lives of the respective assets, generally two to ten years.

Long-lived Assets — The Company evaluates its long-lived assets for impairment in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” whenever events or changes in circumstances indicate that the carrying amount of that asset may not be recoverable. An impairment loss would

be recognized when the sum of the undiscounted future net cash flows expected to result from the use of the asset and its eventual disposition is less than its carrying amount. Measurement of an impairment loss for long-lived assets and certain identifiable intangible assets that management expects to hold and use is based on the fair value of the asset. As of December 31, 2005, management believes that no impairment losses are required.

Product Warranty — The Company sells the majority of its products with warranties ranging from three to twenty-four months. Historically, warranty-related costs have not been significant.

Revenue Recognition — The Company recognizes revenues in accordance with applicable accounting standards including Staff Accounting Bulletin (“SAB”) No. 104, “Revenue Recognition,” Emerging Issues Task Force (“EITF”) Issue No. 00-21, “Accounting for Revenue Arrangements with Multiple Deliverables,” and the American Institute of Certified Public Accountants (“AICPA”) Statement of Position (“SOP”) 97-2, “Software Revenue Recognition,” as amended. Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or service has been rendered, the fee is fixed and determinable, and collectibility is probable. The Company derives its revenues from three principal sources: royalty and license fees, product sales, and development contracts.

Royalty and license revenue

The Company recognizes royalty and license revenue based on royalty reports or related information received from the licensee as well as time-based licenses of its intellectual property portfolio. Up-front payments under license agreements are deferred and recognized as revenue based on either the royalty reports received or amortized over the license period depending on the nature of the agreement. Advance payments under license agreements that also require the Company to provide future services to the licensee are deferred and recognized over the service period when vendor-specific objective evidence (“VSOE”) related to the value of the services does not exist.

The Company generally recognizes revenue from its licensees under one or a combination of the following models:


License Revenue Model		Revenue Recognition

Perpetual license of intellectual property portfolio based on per unit royalties, no services contracted.		Based on royalty reports received from licensees. No further obligations to licensee exist.


Time-based license of intellectual property portfolio with up-front payments and/or annual minimum royalty requirements, no services contracted.		Based on straight-line amortization of annual minimum/up-front payment recognized over contract period or annual minimum period. No further obligations to licensee exist.


Perpetual license of intellectual property portfolio or technology license along with contract for development work.		Based on cost-to-cost percentage-of-completion accounting method over the service period. Obligation to licensee exists until development work is complete.


License of software or technology, no modification necessary, no services contracted.		Up-front revenue recognition based on SOP 97-2 criteria or EITF No. 00-21, as applicable.

Individual contracts may have characteristics that do not fall within a specific license model or may have characteristics of a combination of license models. Under those circumstances, the Company recognizes revenue in accordance with SAB No. 104, EITF No. 00-21, and SOP 97-2, as amended, to guide the accounting treatment for each individual contract. See also comments regarding “Multiple element arrangements” below. If the information received from the Company’s licensees regarding royalties is incorrect or inaccurate, the Company’s revenues in future periods may be adversely affected. To date, none of the information the Company has received from the Company’s licensees has caused any material adjustment to period revenues.

Product sales

The Company recognizes revenues from product sales when the product is shipped, provided that collection is determined to be probable and no significant obligation remains. The Company sells the majority of its products with warranties ranging from 3 to 24 months. The Company records the estimated warranty costs during the quarter the revenue is recognized. Historically, warranty-related costs and related accruals have not been significant. The Company offers a general right of return on the MicroScribe product line for 14 days after purchase. The Company recognizes revenue at the time of shipment of a MicroScribe digitizer and provides an accrual for potential returns based on historical experience. No other general right of return is offered on its products.

Development contracts and other revenue

Multiple element arrangements

The Company enters into revenue arrangements in which the customer purchases a combination of patent, technology, and/or software licenses, products, professional services, support, and extended warranties (multiple element arrangements). When VSOE of fair value exists for all elements, the Company allocates revenue to each element based on the relative fair value of each of the elements. The price charged when the element is sold separately generally determines the fair value or VSOE. For arrangements where VSOE of fair value exists only for the undelivered elements, the Company defers the full fair value of the undelivered elements and recognizes the difference between the total arrangement fee and the amount deferred for the undelivered items as revenue, assuming all other criteria for revenue recognition have been met.

The Company’s revenue recognition policies are significant because the Company’s revenues are a key component of its results of operations. In addition, the Company’s revenue recognition determines the timing of certain expenses, such as commissions and royalties.

Advertising — Advertising costs (including obligations under cooperative marketing programs) are expensed as incurred and included in sales and marketing expense. Advertising expense was $179,000, $166,000, and $166,000 in 2005, 2004, and 2003, respectively.

Research and Development — Research and development costs are expensed as incurred. The Company has generated revenues from development contracts with the United States government and other commercial customers that have enabled it to accelerate its own product development efforts. Such development revenues have only partially funded the Company’s product development activities, and the Company generally retains ownership of the products developed under these arrangements. As a result, the Company classifies all development costs related to these contracts as research and development expenses.

Income Taxes — The Company provides for income taxes using the asset and liability approach defined by SFAS No. 109, “Accounting for Income Taxes.” Deferred tax assets and liabilities are recognized for the expected tax consequences between the tax bases of assets and liabilities and their reported amounts. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized and are reversed at such time that realization is believed to be more likely than not.

Software Development Costs — Certain of the Company’s products include software. Costs for the development of new software products and substantial enhancements to existing software products are expensed as incurred until technological feasibility has been established, at which time any additional costs would be capitalized in accordance with SFAS No. 86, “Computer Software to be Sold, Leased or Otherwise Marketed.” The Company considers technological feasibility to be established upon completion of a working model of the software and the

related hardware. Because the Company believes its current process for developing software is essentially completed concurrently with the establishment of technological feasibility, no costs have been capitalized to date.

Stock-Based Compensation — The Company has accounted for its stock-based awards to employees using the intrinsic value method in accordance with APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and its related interpretations. The Company accounts for stock-based awards to non-employees in accordance with SFAS No. 123, ”Accounting for Stock-Based Compensation.” Pro forma disclosures required under SFAS No. 123, as if the Company had adopted the fair value based method of accounting for stock options, are as follows (in thousands, except per share amounts):


	Years Ended December 31,
	2005			2004			2003

Net loss — as reported	$	(13,085	)	$	(20,738	)	$	(16,974	)
Add: Stock-based employee compensation included in reported net loss, net of related tax effects		2			128			861
Less: Stock-based compensation expense determined using fair value method, net of tax		(5,088	)		(6,663	)		(4,134	)

Net loss — pro forma	$	(18,171	)	$	(27,273	)	$	(20,247	)

Basic and diluted loss per common share — as reported	$	(0.54	)	$	(0.91	)	$	(0.83	)
Basic and diluted loss per common share — pro forma	$	(0.76	)	$	(1.20	)	$	(1.00	)

In December 2004, the FASB issued SFAS No. 123R, “Share-Based Payment.” SFAS No. 123R eliminates the alternative of applying the intrinsic value measurement provisions of APB 25 to stock compensation awards issued to employees. The Company will adopt SFAS No. 123R during the Company’s first quarter of fiscal 2006. See discussion regarding SFAS No. 123R below in the section titled “Recent Accounting Pronouncements.”

Comprehensive Loss — Comprehensive loss includes net loss as well as other items of comprehensive income (loss). The Company’s other comprehensive income (loss) consists of unrealized gains and losses on available-for-sale securities and foreign currency translation adjustments. Total comprehensive loss and the components of accumulated other comprehensive income (loss) are presented in the accompanying Consolidated Statement of Stockholders’ Equity (Deficit).

Net Loss per Share — Basic net loss per share excludes dilution and is computed by dividing net loss by the weighted average number of common shares outstanding for the period (excluding shares subject to repurchase). Diluted net loss per common share was the same as basic net loss per common share for all periods presented since the effect of any potentially dilutive securities is excluded, as they are anti-dilutive because of the Company’s net losses.

Use of Estimates — The preparation of consolidated financial statements and related disclosures in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Concentration of Credit Risks — Financial instruments that potentially subject the Company to a concentration of credit risk principally consist of cash and cash equivalents, short-term investments, and accounts receivable. The Company invests primarily in money market accounts, commercial paper, and debt securities of U.S. government agencies. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand. The Company sells products primarily to companies in North America, Europe, and the Far East. To reduce credit risk, management performs periodic credit evaluations of its customers’ financial condition. The Company maintains reserves for estimated potential credit losses, but historically has not experienced any significant losses related to individual customers or groups of customers in any particular industry or geographic area.

Certain Significant Risks and Uncertainties — The Company operates in a dynamic industry and, accordingly, can be affected by a variety of factors. For example, management of the Company believes that changes in any of the following areas could have a negative effect on the Company in terms of its future financial position and results of operations: its ability to obtain additional financing; the mix of revenues; the loss of significant customers; fundamental changes in the technology underlying the Company’s products; market acceptance of the Company’s and its licensees’ products under development; the availability of contract manufacturing capacity; development of sales channels; litigation or other claims in which the Company is involved; the ability to successfully assert its patent rights against others; the hiring, training, and retention of key employees; successful and timely completion of product and technology development efforts; and new product or technology introductions by competitors.

The Company has incurred net losses each year since 1997 including losses of $13.1 million in 2005, $20.7 million in 2004, and $17.0 million in 2003. As of December 31, 2005, the Company had an accumulated deficit of $126.8 million. The Company believes its cash and cash equivalents of $28.2 million are sufficient to meet its anticipated cash needs for working capital and capital expenditures through at least December 31, 2006. If cash generated from operations is insufficient to satisfy the Company’s liquidity requirements, the Company may seek to raise additional financing or reduce the scope of its planned product development and marketing efforts.

Supplier Concentrations — The Company depends on a number of single source suppliers to produce some of its medical simulators and certain other components. While the Company seeks to maintain a sufficient level of supply and endeavors to maintain ongoing communications with these suppliers to guard against interruptions or cessation of supply, any disruption in the manufacturing process from its sole source suppliers could adversely affect the Company’s ability to deliver its products and ensure quality workmanship and could result in a reduction of the Company’s product sales.

Fair Value of Financial Instruments — Financial instruments consist primarily of cash equivalents, short-term investments, accounts receivable, accounts payable, and long-term debt. Cash equivalents and short-term investments are stated at fair value based on quoted market prices. The recorded cost of accounts receivable, accounts payable, and long-term debt approximate the fair value of the respective assets and liabilities.

Foreign Currency Translation — The functional currency of the Company’s foreign subsidiary is its local currency. Accordingly, gains and losses from the translation of the financial statements of the foreign subsidiary are reported as a separate component of accumulated other comprehensive income (loss). Foreign currency transaction gains and losses are included in earnings.

Recent Accounting Pronouncements — The Company has accounted for stock-based compensation awards issued to employees using the intrinsic value measurement provisions of Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”). Accordingly, no compensation expense was recorded for stock options granted with exercise prices greater than or equal to the fair value of the underlying common stock at the option grant date. In December 2004, the FASB issued SFAS No. 123R, “Share-Based Payment.” SFAS No. 123R eliminates the alternative of applying the intrinsic value measurement provisions of APB 25 to stock compensation awards issued to employees. Rather, the new standard requires enterprises to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost will be recognized over the period during which an employee is required to provide services in exchange for the award, known as the requisite service period (usually the vesting period). In March 2005, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 107 (“SAB 107”) relating to the adoption of SFAS No. 123R. SFAS No. 123R will be effective for the Company’s first quarter of fiscal 2006. The Company expects that the new standard will result in significant stock-based compensation expense.

The pro forma effects on net income and earnings per share, as if the Company had applied the fair value recognition provisions of original SFAS No. 123 on stock compensation awards (rather than applying the intrinsic value measurement provisions of APB 25), are disclosed above. Although such pro forma effects of applying original SFAS No. 123 may be indicative of the effects of adopting SFAS No. 123R, the provisions of these two statements differ in some important aspects. The actual effects of adopting SFAS No. 123R will be dependent on numerous factors including, but not limited to, the valuation model chosen by the Company to value stock-based awards; the assumed award forfeiture rate; the accounting policies adopted concerning the method of recognizing the fair value of awards over the requisite service period; and the transition method. The Company plans to use the

modified prospective application method upon its adoption of SFAS No. 123R. Accordingly, SFAS No. 123R will be applied to new awards and to awards modified, repurchased, or cancelled after the effective date. The compensation cost for the portion of awards for which the requisite service has not been rendered, (such as unvested options) that are outstanding as of the date of adoption, is recognized as the remaining requisite services are rendered. The compensation cost relating to unvested awards at the date of adoption is based on the grant-date fair value of those awards as calculated for pro forma disclosures under the original SFAS No. 123 as adjusted for the effect of estimated forfeiture rates.

5% Senior Subordinated Convertible Debenture (“5% Convertible Debenture”). On December 23, 2004, the Company issued an aggregate principal amount of $20.0 million of 5% Convertible Debentures. The 5% Convertible Debentures will mature on December 22, 2009. The amount payable at maturity of each 5% Convertible Debenture is the initial principal plus all accrued but unpaid interest thereon, to the extent such principal amount and interest have not been converted into common shares or previously paid in cash. The Company cannot prepay the 5% Convertible Debenture except as described below in “Mandatory Conversion and Mandatory Redemption of 5% Convertible Debentures at the Company’s Option.” Interest accrues daily on the principal amount of the 5%

Convertible Debenture at a rate of 5% per year. Interest is payable on the last day of each calendar quarter, and commenced on March 31, 2005. Interest will cease to accrue on that portion of the 5% Convertible Debenture that is converted or paid, including pursuant to conversion right or redemption. The holder of a 5% Convertible Debenture has the right to convert the outstanding principal amount and accrued and unpaid interest, in whole or in part, into the Company’s common shares at a price of $7.0265 per common share, the Conversion Price. In the event of a change of control, a holder may require the Company to redeem all or a portion of their 5% Convertible Debenture. This is referred to as the Put Option. The redeemed portion shall be redeemed at a price equal to the redeemed amount multiplied by (a) 110% of the principal amount of the 5% Convertible Debenture if the change of control occurs on or prior to December 23, 2005, (b) 105% of the principal amount of the 5% Convertible Debenture if the change of control occurs after December 23, 2005 and on or prior to December 23, 2006, or (c) 100% of the principal amount of the 5% Convertible Debenture if the change of control occurs after December 23, 2006. The Conversion Price will be reduced in certain instances where shares of common stock are sold or deemed to be sold at a price less than the applicable Conversion Price, including the issuance of certain options, the issuance of convertible securities, or the change in exercise price or rate of conversion for options or convertible securities. The Conversion Price will be proportionately adjusted if the Company subdivides (by stock split, stock dividend, recapitalization, or otherwise) or combines (by combination, reverse stock split, or otherwise) one or more classes of its common stock. So long as any 5% Convertible Debentures are outstanding, the Company will not, nor will the Company permit any of its subsidiaries to directly or indirectly incur or guarantee, assume or suffer to exist, any indebtedness other than permitted indebtedness under the 5% Convertible Debenture agreement. If an event of default occurs, and is continuing with respect to any of the Company’s 5% Convertible Debentures, the holder may, at its option, require the Company to redeem all or a portion of the 5% Convertible Debenture.

Mandatory Conversion and Mandatory Redemption of 5% Convertible Debentures at the Company’s Option. Commencing on December 23, 2005, if the daily volume-weighted average price of the Company’s common shares is at or above 200% of the Conversion Price for at least 20 consecutive trading days and certain other conditions are met, the Company has the right to (i) require the holder of a 5% Convertible Debenture to convert the 5% Convertible Debenture in whole, including interest, into shares of the Company’s common stock at a price of $7.0265 per common share, as may be adjusted under the debenture, as set forth and subject to the conditions in the 5% Convertible Debenture, or (ii) redeem the 5% Convertible Debenture. If the Company makes either of the foregoing elections with respect to any 5% Convertible Debenture, the Company must make the same election with respect to all 5% Convertible Debentures.

Warrants. On December 23, 2004, in connection with the issuance of the 5% Convertible Debentures, the Company issued warrants to purchase an aggregate of 426,951 shares of its common stock at an exercise price of $7.0265. The warrants may be exercised at any time prior to 5:00 p.m. Eastern time, on December 23, 2009. Any warrants not exercised prior to such time will expire. The exercise price will be reduced in certain instances where shares of common stock are sold or deemed to be sold at a price less than the applicable exercise price, including the issuance of certain options, the issuance of convertible securities, or the change in exercise price or rate of conversion for option or convertible securities. The exercise price will be proportionately adjusted if the Company subdivides (by stock split, stock dividend, recapitalization, or otherwise) or combines (by combination, reverse stock split, or otherwise) one or more classes of its common stock.

Registration Rights. On April 18, 2005, the Company’s registration statement relating to the 5% Convertible Debentures, and the shares of common stock issuable upon conversion of the debentures, was declared effective by the SEC. The Company expects to keep this registration statement effective until the earlier of (i) such time as all of the shares covered by the prospectus have been disposed of pursuant to and in accordance with the registration statement, or (ii) the date on which the shares may be sold pursuant to Rule 144(k) of the Securities Act.

The Company incurred approximately $1.3 million in issuance costs and other expenses in connection with the offering. This amount has been deferred and is being amortized to interest expense over the term of the 5% Convertible Debenture. Additionally, the Company evaluated the various instruments included in the agreements entered into on December 22, 2004 and allocated the relative fair values to be as follows: warrants — $1.7 million, Put Option — $0.1 million, Registration Rights — $0.1 million, issuance costs — $1.3 million, 5% Convertible Debenture — $16.8 million. The 5% Convertible Debentures will be accreted to $20.0 million over their five-year life, resulting in additional interest expense. The value of the warrants has been included in Stockholders’ Deficit; the value of the Put

Option and Registration Rights have been recorded as a liability and are subject to future value adjustments; and the value of the 5% Convertible Debentures has been recorded as long-term debt.

Annual maturities of long-term debt at December 31, 2005 are as follows (in thousands):

8.	Long-term Deferred Revenue

At December 31, 2005, long-term deferred revenue included payments of approximately $16.8 million of compulsory license fees and interest from Sony Computer Entertainment Inc. and Sony Computer Entertainment of America Inc. (collectively, “Sony Computer Entertainment”), pursuant to Court rulings on January 10 and February 9, 2005. Due to the contingent nature of the court-order payments made by Sony Computer Entertainment, the Company will not record any revenue or interest associated with these payments as revenue or income until such time as the contingency lapses.

9. Long-term Customer Advance from Microsoft

On July 25, 2003, the Company contemporaneously executed a series of agreements with Microsoft Corporation (“Microsoft”) that (1) settled the Company’s lawsuit against Microsoft, (2) granted Microsoft a worldwide royalty-free, irrevocable license to the Company’s portfolio of patents (the “License Agreement”) in exchange for a payment of $19.9 million, (3) provided Microsoft with sublicense rights to pursue certain license arrangements directly with third parties including Sony Computer Entertainment which, if consummated, would result in payments to the Company (the “Sublicense Rights”), and conveyed to Microsoft the right to a payment of cash in the event of a settlement within certain parameters of the Company’s patent litigation against Sony Computer Entertainment of America Inc. and Sony Computer Entertainment Inc. (the “Participation Rights”) in exchange for a payment of $0.1 million, (4) issued Microsoft shares of the Company’s Series A Redeemable Convertible Preferred Stock (“Series A Preferred Stock”) for a payment of $6.0 million, and (5) granted the Company the right to sell debentures of $9.0 million to Microsoft under the terms and conditions established in newly authorized 7% Senior Redeemable Convertible Debentures (“7% Debentures”) with annual draw down rights over a 48-month period.

Under these agreements, in the event of a settlement of the Sony Computer Entertainment litigation under certain terms, the Company will be required to make a cash payment to Microsoft of (i) an amount to be determined based on the settlement proceeds, and (ii) any funds received from Microsoft under the 7% Debentures. As discussed in Note 18, regarding the Sony Computer Entertainment litigation, the Court entered judgment in the Company’s favor and awarded the Company $82.0 million in past damages and pre-judgment interest in the amount of $8.7 million. On June 16, 2005, Sony Computer Entertainment filed its notice of appeal of the judgment based upon the jury verdict; the Company intends to vigorously pursue its claims against Sony Computer Entertainment.

On April 2, 2004, Microsoft elected to convert 2,185,792 shares of Series A Preferred Stock into 2,185,792 shares of common stock. This conversion eliminated certain obligations, such as the mandatory redemption buy-back provision, the obligation to make dividend payments, and certain operational limitations.

In the event of a settlement of the Sony Computer Entertainment litigation, the Company will realize and retain net cash proceeds received from Sony Computer Entertainment only to the extent that settlement proceeds exceed the amounts due Microsoft for its Participation Rights and any outstanding 7% Debentures and interest as specified above. Under certain circumstances related to a Company initiated settlement with Sony Computer Entertainment, the Company would be obligated to pay Microsoft a minimum of $15.0 million. In the event of an unfavorable judicial resolution or a dismissal or withdrawal by the Company of the lawsuit meeting certain conditions, the Company would not be required to make any payments to Microsoft except pursuant to the payment provisions relating to any outstanding 7% Debentures.

Under the terms of the Senior Redeemable Convertible Debentures agreement, the Company can sell up to $3.0 million of the 7% Debentures the first year and $2.0 million per year for the following three years. Debenture proceeds may only be used to finance the Sony Computer Entertainment litigation. The 7% Debentures are callable by Microsoft after three years at 110%. They are also callable by Microsoft upon settlement of the Sony Computer Entertainment litigation at 125% of par. The 7% Debentures are convertible into common stock at 364 shares/$1,000 face value (based on $2.745 per share). Under certain specified circumstances, including the acquisition of the Company, any outstanding 7% Debentures would become immediately due and payable. The Company has, to date, not sold any 7% Debentures.

The $26.0 million received from Microsoft, as described above, plus an additional $1.4 million related to accretion and cumulative dividends, was reflected as a liability in the financial statements as of March 31, 2004. Upon Microsoft’s election to convert its shares of the Company’s Series A Preferred Stock into common stock in April 2004, the Company reduced the long-term customer advance from Microsoft to the minimum $15.0 million obligation the Company would be obligated to pay Microsoft upon a settlement with Sony Computer Entertainment. The remainder of consideration of $12.4 million was transferred to common stock when Microsoft elected to convert the Series A Preferred Stock to common stock.


10.	Restructuring Costs

The Company accounts for restructuring costs in accordance with SFAS No. 146, “Accounting for Costs Associated with Exit of Disposal Activities.” Restructuring costs of $185,000 incurred in the year ended December 31, 2005 consisted of severance benefits paid as a result of a reduction in workforce of approximately 10% in early 2005. Employees from manufacturing, sales and marketing, research and development, and general and administrative were included in the reduction in force. The Company did not incur any additional charges related to the aforementioned reduction in force and management does not anticipate any further costs in future periods related to this reduction in force.

Stock Options. Under the Company’s stock option plans, the Company may grant options to purchase up to 15,120,074 shares of common stock to employees, directors, and consultants at prices not less than the fair market value on the date of grant for incentive stock options and not less than 85% of fair market value on the date of grant for nonstatutory stock options. These options generally expire 10 years from the date of grant. The Company has granted immediately exercisable options as well as options that become exercisable over periods ranging from three months to five years.

Additional Stock Plan Information. As discussed in Note 1, the Company has accounted for its stock-based awards using the intrinsic value method in accordance with APB Opinion No. 25 and its related interpretations. SFAS No. 123 requires the disclosure of pro forma net loss had the Company adopted the fair value method as of the beginning of fiscal 1996. Under SFAS No. 123, the fair value of stock-based awards to employees is calculated through the use of option pricing models, even though these models were developed to estimate the fair value of freely tradable, fully transferable options without vesting restrictions, which significantly differ from the Company’s stock option awards. These models also require subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. The Company used the Black-Scholes option pricing model and based its calculations on a multiple option valuation approach recognizing forfeitures as they occur. The Company’s calculations were made using the following weighted average assumptions:


	Options									Employee Stock Purchase Plan
	2005			2004			2003			2005			2004			2003

Expected life (in years)		2.5			2.5			2.5			0.5			0.5			0.5
Interest rate		4.1	%		2.8	%		2.8	%		3.7	%		1.4	%		1.2	%
Volatility		63	%		107	%		124	%		33	%		92	%		132	%
Dividend yield		—			—			—			—			—			—

The Company considers a number of factors in determining how to set its volatility rates in these calculations, including historical stock price movement, the volatility of stock prices of companies of similar size with similar businesses to the Company’s, if any, and the expected future stock price trends of the Company based on known and anticipated events, including events related to revenues, costs, and litigation. The Company currently considers its historical stock price movement and future stock price trends as the best indicator of future volatility and has set its volatility rates based on these factors.

Employee Stock Purchase Plan. The Company has an employee stock purchase plan (“ESPP”). Under the ESPP, eligible employees may purchase common stock through payroll deductions at a purchase price of 85% of the lower of the fair market value of the Company’s stock at the beginning of the offering period or the purchase date. Participants may not purchase more than 2,000 shares in a six-month offering period or stock having a value greater than $25,000 in any calendar year as measured at the beginning of the offering period. A total of 500,000 shares of common stock are reserved for the issuance under the ESPP plus an automatic annual increase on January 1, 2001 and on each January 1 thereafter through January 1, 2010 by an amount equal to the lesser of 500,000 shares per year or a number of shares determined by the Board of Directors. As of December 31, 2005, 246,804 shares had been purchased under the plan.

Deferred Stock Compensation. In January 2000, Immersion Medical’s Board of Directors approved a repricing of all outstanding stock options relating to Immersion Medical that had been granted on or after June 1, 1998 from $15.46 per share to $7.73 per share. A total of 30,797 options were repriced. Under APB 25 the repricing requires that compensation associated with these options be remeasured until they are exercised, forfeited, or expire. During the years ended December 31, 2005, 2004, and 2003, the Company did not record any deferred stock compensation in connection with these repriced options, as the price of the Company’s stock was not higher than the repriced amount at any quarter-end during those periods. Effective January 01, 2006, any future compensation expense related to these options will be accounted for in accordance with SFAS No. 123R.

In fiscal 2000, in connection with two business combinations accounted for under the purchase method, the Company recorded $5.8 million of deferred stock compensation which represented the intrinsic value of unvested assumed stock options, and was being amortized over the respective remaining service periods on a straight-line basis. As of December 31, 2005 all deferred stock compensation was fully amortized.

Warrants. On December 23, 2004, the Company, in conjunction with the 5% Convertible Debentures, issued an aggregate of 426,951 warrants to purchase shares of its common stock at an exercise price of $7.0265. The warrants may be exercised at any time prior to 5:00 p.m. Eastern time, on December 23, 2009. Any warrants not exercised prior to such time will expire. The Company allocated $1.7 million of the 5% Convertible Debenture proceeds to the warrant and will amortize the amount to interest expense over the five-year term of the 5% Convertible Debentures. See Note 7.


13.	Net Loss Per Share

The following is a reconciliation of the numerators and denominators used in computing basic and diluted net loss per share (in thousands, except per share data):

14.	Income Taxes

For the year ended December 31, 2005, the Company recorded a provision for income taxes of $158,000 yielding an effective tax rate of (1.2)%. The provision for income tax was based on federal and state alternative minimum income tax payable on taxable income and foreign withholding tax expense. Although the Company incurred a pre-tax loss, sums received from Sony Computer Entertainment and interest thereon included in long-term deferred revenue, approximating $16.8 million for the year ended December 31, 2005, created alternativeminimum taxable income. For the year ended December 31, 2004, the Company reversed the tax provision that had been recorded in 2003 due to the non-recognition of deferred revenues for 2003 tax return purposes.

Significant components of the net deferred tax assets and liabilities for federal and state income taxes consisted of (in thousands):


	December 31,

Deferred stock compensation		—			0.2
Other		1.4			(0.2	)
Valuation allowance		39.5			37.3

Effective tax rate		1.2	%		(0.7	)%

Substantially all of the Company’s loss from operations for all periods presented is generated from domestic operations.

At December 31, 2005, the Company has federal and state net operating loss carryforwards of $75.9 million and $27.0 million, respectively, expiring from 2011 through 2025 and from 2007 through 2015, respectively.

Amongst the net operating loss carryforwards, approximately $4.0 million and $2.0 million of federal and state net operating loss carryforwards were generated prior to 1999. These losses can be used to offset future taxable income. Usage is limited to approximately $16.4 million annually, due to an ownership change that occurred during 1999. Approximately $10.6 million of federal and state net operating loss carryforwards related to pre-acquisition losses from acquired subsidiaries can be used to offset future taxable income. Usage of pre-acquisition losses will be limited to approximately $1.1 million annually. During 2005, the Company evaluated ownership changes from 1999 to 2004 and determined that there were no further limitations on the Company’s net operating loss carryforwards.

Undistributed earnings of the Company’s foreign subsidiaries are considered to be indefinitely reinvested and accordingly, no provision for federal and state income taxes has been provided thereon. Upon distribution of those earnings in the form of dividends or otherwise, the Company would be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to various foreign countries.


15.	Employee Benefit Plan

The Company has a 401(k) tax-deferred savings plan under which eligible employees may elect to have a portion of their salary deferred and contributed to the 401(k) plan. Contributions may be made by the Company at the discretion of the Board of Directors. The Company did not make any contributions during the years ended December 31, 2005, 2004, or 2003.


16.	Government Audits

Billings under certain cost-based government contracts are calculated using provisional rates that permit recovery of indirect costs. These rates are subject to audit on an annual basis by the government agencies’ audit department. The cost audit will result in the negotiation and determination of the final indirect cost rates that the Company may use for the period(s) audited. The final rates, if different from the provisionals, may create an additional receivable or liability.

As of December 31, 2005, the Company has not reached final settlements on indirect rates. The Company has negotiated provisional indirect rates for the years ended December 31, 2005, 2004, and 2003. The Company periodically reviews its cost estimates and experience rates, and any needed adjustments are made and reflected in the period in which the estimates are revised. In the opinion of management, redetermination of any cost-based contracts for the open years will not have a material effect on the Company’s financial position or results of operations.


17.	Related Parties

In July 2003 the Company entered into a consulting agreement with a member of its board of directors to assist with certain marketing initiatives of its wholly owned subsidiary, Immersion Medical. Under the terms of the

consulting agreement the board member received $15,000 per month compensation and reimbursement of out-of-pocket travel expenses. The initial term of the consulting agreement was six months and was renewable for subsequent three-month terms unless either party notified the other of its election to terminate the agreement. The consulting agreement was terminated in April 2004. During the years ended December 31, 2004 and December 31, 2003 the board member earned compensation of $50,000 and $90,000, respectively.

The Company is involved in legal proceedings relating to a class action lawsuit filed on November 9, 2001, In re Immersion Corporation Initial Public Offering Securities Litigation, No. Civ. 01-9975 (S.D.N.Y.), related to In re Initial Public Offering Securities Litigation, No. 21 MC 92 (S.D.N.Y.). The named defendants are the Company and three of its current or former officers or directors (the “Immersion Defendants”), and certain underwriters of the Company’s November 12, 1999 initial public offering (“IPO”). Subsequently, two of the individual defendants stipulated to a dismissal without prejudice.

The operative amended complaint is brought on purported behalf of all persons who purchased the common stock of the Company from the date of the IPO through December 6, 2000. It alleges liability under Sections 11 and 15 of the Securities Act of 1933 and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, on the grounds that the registration statement for the IPO did not disclose that: (1) the underwriters agreed to allow certain customers to purchase shares in the IPO in exchange for excess commissions to be paid to the underwriters; and (2) the underwriters arranged for certain customers to purchase additional shares in the aftermarket at predetermined prices. The complaint also appears to allege that false or misleading analyst reports were issued. The complaint does not claim any specific amount of damages.

Similar allegations were made in other lawsuits challenging over 300 other initial public offerings and follow-on offerings conducted in 1999 and 2000. The cases were consolidated for pretrial purposes. On February 19, 2003, the Court ruled on all defendants’ motions to dismiss. The motion was denied as to claims under the Securities Act of 1933 in the case involving Immersion, as well as in all other cases (except for 10 cases). The motion was denied as to the claim under Section 10(b) as to the Company, on the basis that the complaint alleged that the Company hadmade acquisition(s) following the IPO. The motion was granted as to the claim under Section 10(b), but denied as to the claim under Section 20(a), as to the remaining individual defendant.

The Company and most of the issuer defendants have settled with the plaintiffs. In this settlement, plaintiffs have dismissed and released all claims against the Immersion Defendants, in exchange for a contingent payment by the insurance companies collectively responsible for insuring the issuers in all of the IPO cases, and for the assignment or surrender of certain claims the Company may have against the underwriters. The Immersion Defendants will not be required to make any cash payments in the settlement, unless the pro rata amount paid by the insurers in the settlement exceeds the amount of the insurance coverage, a circumstance which the Company believes is remote. The settlement will require approval of the Court, which cannot be assured, after class members are given the opportunity to object to the settlement or opt out of the settlement.

Immersion Corporation vs. Microsoft Corporation, Sony Computer Entertainment Inc. and Sony Computer Entertainment of America, Inc.

On February 11, 2002, the Company filed a complaint against Microsoft Corporation, Sony Computer Entertainment, Inc., and Sony Computer Entertainment of America, Inc. in the U.S. District Court for the Northern District Court of California alleging infringement of U.S. Patent Nos. 5,889,672 and 6,275,213. The case was assigned to United States District Judge Claudia Wilken. On April 4, 2002, Sony ComputerEntertainment and Microsoft answered the complaint by denying the material allegations and alleging counterclaims seeking a judicial declaration that the asserted patents were invalid, unenforceable, or not infringed. Under the counterclaims, the defendants were also seeking damages for attorneys’ fees. On October 8, 2002, the Company filed an amended complaint, withdrawing the claim under the U.S. Patent No. 5,889,672 and adding claims under a new patent, U.S. Patent No. 6,424,333.

On July 28, 2003, the Company announced that it had settled its legal differences with Microsoft, and the Company and Microsoft agreed to dismiss all claims and counterclaims relating to this matter as well as assume financial responsibility for their respective legal costs with respect to the lawsuit between the Company and Microsoft.

On August 16, 2004, the trial against Sony Computer Entertainment commenced. On September 21, 2004, the jury returned its verdict in favor of the Company. The jury found all the asserted claims of the patents valid and infringed. The jury awarded the Company damages in the amount of $82.0 million. On January 10, 2005, the Court awarded the Company prejudgment interest on the damages the jury awarded at the applicable prime rate. The Court further ordered Sony Computer Entertainment to pay the Company a compulsory license fee at the rate of 1.37%, the ratio of the verdict amount to the amount of sales of infringing products, effective as of July 1, 2004 and through the date of Judgment. On February 9, 2005, the Court ordered that Sony Computer Entertainment provide the Company with sales data 15 days after the end of each quarter and clarifying that Sony Computer Entertainment shall make the ordered payment 45 days after the end of the applicable quarter. Sony Computer Entertainment has made quarterly payments to the Company pursuant to the Court’s orders. Although the Company has received payments, the Company may be required to return them and any future payments based on the outcome of the appeals process.

On January 5 and 6, 2005, the Court held a bench trial on Sony Computer Entertainment’s remaining allegations that the ’333 patent was not enforceable due to alleged inequitable conduct. On March 24, 2005, the Court resolved this issue, entering a written order finding in favor of the Company. On March 24, 2005, Judge Wilken also entered judgment in the Company’s favor and awarded the Company $82.0 million in past damages, and pre-judgment interest in the amount of $8.7 million, for a total of $90.7 million. The Company was also awarded its court costs. Court costs do not include attorneys’ fees.

Additionally, the Court issued a permanent injunction against the manufacture, use, sale, or import into the United States of the infringing Sony Computer Entertainment PlayStation system consisting of the PlayStation consoles, Dual Shock controllers, and the 47 games found by the jury to infringe the Company’s patents. The Court stayed the permanent injunction pending appeal to the United States Court of Appeals for the Federal Circuit. TheCourt further ordered Sony Computer Entertainment to pay a compulsory license fee at the rate of 1.37% for the duration of the stay of the permanent injunction at the same rate and conditions as previously awarded in its interim January 10, 2005 and February 9, 2005 Orders. On April 7, 2005 pursuant to a stipulation of the parties, the Court entered an Amended Judgment to clarify that the Judgment in favor of the Company and against Sony Computer Entertainment also encompassed Sony Computer Entertainment’s counterclaims for declaratory relief on invalidity and unenforceability, as well as non-infringement.

reexamination procedures deny due process of law. The PTO denied the first petition, and the Company filed a second petition on September 9, 2005. On November 17, 2005, the PTO granted the Company’s petition, and suspended the inter partes reexaminations until such time as the parallel court proceedings warrant termination or resumption of the PTO examination and prosecution proceedings. On December 13, 2005, Sony Computer Entertainment filed a third petition requesting permission to file an additional inter partes reexamination on the claims of the ‘333 and ’213 Patents for which reexamination was not requested in Sony Computer Entertainment’s original requests for reexamination; the Company has opposed this petition. The PTO has not yet issued a decision on Sony Computer Entertainment’s third petition. Sony Computer Entertainment also filed ex parte reexamination requests on the claims of the ‘333 and ‘213 Patents on December 13, 2005.

On June 16, 2005, Sony Computer Entertainment filed a Notice of Appeal from the District Court Judgment to the United States Court of Appeals for the Federal Circuit. The appeals of the January and February orders regarding the compulsory license have been consolidated with this appeal of the Judgment. Sony Computer Entertainment’s Opening Brief was filed on October 21, 2005; the Company filed an Opposition Brief on December 5, 2005. Due to the cross appeal by ISLLC (see below), the Federal Circuit allowed the Company to file a Substitute Opposition Brief on February 17, 2006 responding to the briefs filed by both Sony Computer Entertainment and ISLLC. We expect the briefing for the appeal to be concluded by all parties by the end of March 2006.

On July 21, 2005, Sony Computer Entertainment filed a motion in the District Court before Judge Wilken seeking relief from the final judgment under Rule 60(b) of the Federal Rules of Civil Procedure on the grounds of alleged fraud and “newly discovered evidence” of purported prior art which Sony Computer Entertainment contends the Company concealed and withheld attributable to Mr. Craig Thorner, a named inventor on three patents that Sony Computer Entertainment urged as a basis for patent invalidity during the trial. the Company disputes and intends to vigorously defend itself against these allegations. Briefing is complete, and a hearing was held before Judge Wilken on January 20, 2006. On March 8, 2006, the Court denied Sony Computer Entertainment’s motion pursuant to Rule 60(b) of the Federal Rules of Civil Procedure in its entirety.

Due to the inherent uncertainties of litigation, the Company cannot accurately predict how the Court of Appeals will decide the appeal. The Company anticipates that the litigation will continue to be costly, and there can be no assurance that the Company will be able to recover the costs we incur in connection with the litigation. The Company expenses litigation costs as incurred and only accrues for costs that have been incurred but not paid to the vendor as of the financial statement date. The litigation has diverted, and is likely to continue to divert, the efforts and attention of some of the Company’s key management and personnel. As a result, until such time as it is resolved, the litigation could adversely affect the Company’s business. Further, any unfavorable outcome could adversely affect the Company’s business.

In the event the Company settles its lawsuit with Sony Computer Entertainment, the Company will be obligated to pay certain sums to Microsoft as described in Note 9. If Sony Computer Entertainment ultimately were successful on appeal or in the reexamination process, the Judgment may be put at risk, assets relating to the patents in the lawsuit may be impaired, and Sony Computer Entertainment may seek additional relief, such as attorneys’ fees.

Internet Services LLC Litigation

On October 20, 2004, ISLLC, a Company licensee and cross-claim defendant against whom Sony Computer Entertainment had filed a claim seeking declaratory relief, filed claims against the Company alleging that the Company breached a contract with ISLLC by suing Sony Computer Entertainment for patent infringement relating to haptically-enabled software whose topics or images are allegedly age-restricted, for judicial apportionment of damages awarded by the jury between ISLLC and the Company, and for a judicial declaration with respect to ISLLC’s rights and duties under agreements with the Company. On December 29, 2004, the Court issued an order dismissing ISLLC’s claims against Sony Computer Entertainment with prejudice and dismissing ISLLC’s claims against the Company without prejudice to ISLLC filing a new complaint “if it can do so in good faith without contradicting, or repeating the deficiency of, its complaint.”

On January 12, 2005, ISLLC filed Amended Cross-Claims and Counterclaims against the Company that contained similar claims. ISLLC also realleged counterclaims against Sony Computer Entertainment. On

January 28, 2005, the Company filed a motion to dismiss ISLLC’s Amended Cross-Claims and a motion to strike ISLLC’s Counterclaims against Sony Computer Entertainment. On March 24, 2005 the Court issued an order dismissing ISLLC’s claims with prejudice as to ISLLC’s claim seeking a declaratory judgment that it is an exclusive licensee under the ’213 and ’333 patents and as to ISLLC’s claim seeking “judicial apportionment” of the damages verdict in the Sony Computer Entertainment case. The Court’s order further dismissed ISLLC’s claims without prejudice as to ISLLC’s breach of contract and unjust enrichment claims.

ISLLC filed a notice of appeal of those orders with the Federal Circuit on April 18, 2005. ISLLC’s appeal has been consolidated with Sony Computer Entertainment’s appeal. ISLLC filed its Opening Brief in December 2005. As noted above, the Federal Circuit allowed the Company to file a Substitute Opposition Brief on February 17, 2006 responding to the briefs filed by both Sony Computer Entertainment and ISLLC; the Company expects the briefing for the appeal to be concluded by all parties by the end of March 2006.

On February 8, 2006, ISLLC filed a lawsuit against the Company in the Superior Court of Santa Clara County. ISLLC’s complaint seeks a share of the Company’s Judgment and recovery against Sony Computer Entertainment and of the Microsoft settlement proceeds, and generally restates the claims already adjudicated in District Court. The Company’s response to the complaint is due on March 16, 2006.

Immersion Corporation vs. Electro Source LLC

On September 24, 2004, the Company filed in the United States District Court for the Northern District of California a complaint for patent infringement against Electro Source LLC (“Electro Source”) (Case No. 04-CV-4040 CW). Electro Source is a leading seller of video game peripherals under the Pelican Accessories brand. The Company’s Complaint alleged that Electro Source had willfully infringed, and was continuing to willfully infringe, the same two patents asserted in the Company’s litigation against Sony Computer Entertainment. The Complaint sought injunctive relief, as well as damages in an amount to be proven at trial, trebled due to Electro Source’s willful infringement, and attorneys’ fees and costs. Electro Source filed an answer to the Complaint denying the material allegations and asserting against the Company counterclaims seeking a judicial declaration that the asserted patents are invalid, unenforceable, and not infringed.

On February 28, 2006, the Company announced that it had settled its legal differences with Electro Source and the Company and Electro Source agreed to dismiss all claims and counterclaims relating to this matter. In addition to the Confidential Settlement Agreement, Electro Source entered into a worldwide license to the Company’s patents for vibro-tactile devices in the consumer gaming peripheral field of use. Electro Source will make royalty payments to the Company based on sales by Electro Source of spinning mass vibro-tactile gamepads, steering wheels, and other game controllers for dedicated gaming consoles, such as the Sony PlayStation and PlayStation 2, the Nintendo GameCube, and the Microsoft Xbox and Xbox 360. Both companies also have agreed to explore the possibility of working together in technology or engineering related assignments. In March 2006, Electro Source paid the Company $650,000. The Company is entitled to be paid a minimum amount of $1.0 million in future periods. The Company and Electro Source each assumed financial responsibility for their respective legal costs with respect to the lawsuit between the Company and Electro Source.

Other Contingencies

From time to time, the Company receives claims from third parties asserting that the Company’s technologies, or those of its licensees, infringe on the other parties’ intellectual property rights. Management believes that these claims are without merit. Additionally, periodically, the Company is involved in routine legal matters and contractual disputes incidental to its normal operations. In management’s opinion, the resolution of such matters will not have a material adverse effect on the Company’s consolidated financial condition, results of operations, or liquidity.

In the normal course of business, the Company provides indemnifications of varying scope to customers against claims of intellectual property infringement made by third parties arising from the use of the Company’s intellectual property, technology, or products. Historically, costs related to these guarantees have not been significant, and the Company is unable to estimate the maximum potential impact of these guarantees on its future results of operations. The Company has received a claim from one of its major licensees requesting indemnification from a patent infringement allegation. The Company has reviewed this demand and believes that it

is without merit. The Company has not received communication from this licensee with respect to this claim since June of 2005. Such claim, however, could result in litigation, which could be costly and time-consuming to defend. Further, the Company’s business could be adversely affected if the Company was unsuccessful in defending against the claim.

As permitted under Delaware law, the Company has agreements whereby it indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at its request in such capacity. The term of the indemnification period is for the officer’s or director’s lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company currently has director and officer insurance coverage that limits its exposure and enables it to recover a portion of any future amounts paid. Management believes the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.

19.	Segment Reporting

The Company develops, manufactures, licenses, and supports a wide range of hardware and software technologies that let users interact with digital devices using their sense of touch. The Company focuses on four application areas — gaming, mobility, industrial, and medical. The Company manages these application areas under two operating and reportable segments: 1) Immersion Computing, Entertainment, and Industrial, and 2) Immersion Medical. The Company determines its reporting segments in accordance with criteria outlined in SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information.” The gaming, mobility, and industrial areas do not individually meet the criteria for segment reporting as set out in SFAS No. 131.

The Company’s chief operating decision maker (“CODM”) is the Chief Executive Officer. The CODM allocates resources to and assesses the performance of each operating segment using information about their revenue and operating profit before interest and taxes. A description of the types of products and services provided by each operating segment is as follows:

Immersion Computing, Entertainment, and Industrial develops and markets touch feedback technologies that enable software and hardware developers to enhance realism and usability in their computing, entertainment, and industrial applications. Immersion Medical develops, manufactures, and markets medical training simulators that recreate realistic healthcare environments.

Summarized financial information concerning the Company’s reportable segments for the respective years ended December 31 is shown in the following table (in thousands):

Segment assets and expenses relating to the Company’s corporate operations are not allocated but are included in Immersion Computing, Entertainment, and Industrial as that is how they are considered for management evaluation purposes. As a result, the segment information may not be

indicative of the financial position or results of operations that would have been achieved had these segments operated as unaffiliated entities. Management measures the performance of each segment based on several metrics, including net loss. These results are used, in part, to evaluate the performance of, and allocate resources to, each of the segments.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Immersion Corporation:

We have audited the accompanying consolidated balance sheets of Immersion Corporation and subsidiaries (the “Company”) as of December 31, 2005 and 2004, and the related consolidated statements of operations, stockholders’ equity (deficit), and cash flows for each of the three years in the period ended December 31, 2005. Our audits also included the financial statement schedules listed in the Index at Item 15 (a) 2. These financial statements and financial statement schedules are the responsibility of the Company’s management. Our responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Immersion Corporation and subsidiaries at December 31, 2005 and 2004, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2005, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company’s internal control over financial reporting as of December 31, 2005, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 10, 2006 expressed an unqualified opinion on management’s assessment of the effectiveness of the Company’s internal control over financial reporting and an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, management’s assessment that the Company maintained effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial schedule as of and for the year ended December 31, 2005 of the Company and our report dated March 10, 2006 expressed an unqualified opinion on those financial statements and financial statement schedule.

Item 9.	*Changes in and Disagreements with Accountants on Accounting and Financial Disclosure*

None.


Item 9A.	*Controls and Procedures*

Controls and Procedures

Based on their evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of December 31, 2005, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, have concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report for the purpose of ensuring that the information required to be disclosed by us in this Annual Report on Form 10-K is made known to them by others on a timely basis, and that the information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, in order to allow timely decisions regarding required disclosure, and that such information is recorded, processed, summarized, and reported by us within the time periods specified in the SEC’s rules and instructions for Form 10-K.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended). Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2005. In making this assessment, our management used the criteria set forth in the Internal Control-Integrated Framework by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Our management has concluded that, as of December 31, 2005, our internal control over financial reporting is effective based on these criteria. Our independent registered public accounting firm, Deloitte & Touche LLP, has issued an audit report on our assessment of our internal control over financial reporting, which is included herein.

There were no changes to internal controls over financial reporting during the quarter ended December 31, 2005, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any within Immersion, have been detected. Notwithstanding these limitations, our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives. Our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are, in fact, effective at the “reasonable assurance” level.
