Item 5. Other Events.

     On February 28, 2003, Vixel Corporation, prior to Emulex’s acquisition of it, filed a patent infringement action against QLogic Corporation in the United States District Court for the District of Delaware. The complaint states that QLogic is infringing U.S. Patent No. 6,118,776, entitled “Methods and Apparatus for Fiber Channel Interconnections of Private Loop Devices,” through the unauthorized manufacture, use, sale and offering for sale of various storage area network switching products, including but not limited to, QLogic’s SANBox2 series of products. On March 28, 2003, Vixel filed a first amended complaint stating that QLogic is also infringing U.S. Patent No. 6,185,203, entitled “Fibre Channel Switching Fabric’’ and U.S. Patent No. 6,470,007, entitled “Interconnect System for Fibre Channel Arbitrated Loop Including Private Loop Devices’’ through the unauthorized manufacture, use, sale and offering for sale of various storage area network switching products, including but not limited to, QLogic’s SANBox2 series of products. On May 23, 2003, Vixel filed a patent infringement action against Brocade Communications Systems, Inc. in the United States District Court for the Northern District of California. The complaint states that Brocade is infringing U.S. Patent No. 6,185,203, entitled “Fibre Channel Switching Fabric,” U.S. Patent No. 6,118,776, entitled “Methods and Apparatus for Fibre Channel Interconnection of Private Loop Devices,” and U.S. Patent No. 6,470,007, entitled “Interconnect Systems for Fibre Channel Arbitrated Loop Including Private Loop Devices,” through the unauthorized manufacture, use, sale and offering for sale of various storage area network switching products, including Brocade’s Silkworm switch products, which include its “QuickLoop” and “Fabric Assist” product features. In both of these suits the plaintiff is seeking unspecified past damages, potential future royalties, or, alternatively, injunctive relief. QLogic and Brocade have challenged the validity of the patents referenced, and Brocade has also challenged the enforceability of those patents.

     On December 8, 2003, QLogic filed a complaint against Emulex in the United States District Court for the Central District of California alleging that one of Vixel’s products, the 7200 Fibre Channel Switch, infringes U.S. Patent No. 4,821,034, entitled “Digital Exchange Switch Element and Network..” The suit seeks unspecified monetary damages as well as injunctive relief. We believe that QLogic’s complaint is without merit and we intend to defend the lawsuit vigorously.

     Each of the foregoing lawsuits is pending, and presents risks inherent in litigation of this type, any of which could have a material adverse effect on our business, financial condition or results of operations. Such potential risks include the continuing expenses of litigation, the risk of loss of patent rights, the risk of injunction against the sale of products incorporating the technology in question, the risk of a damage award, counterclaims and attorneys fees.
