Explanatory Note

On July 19, 2012, Vringo, Inc., a Delaware corporation (“Vringo” or “Legal Parent”), closed a merger transaction (the “Merger”) with Innovate/Protect, Inc., a privately held Delaware corporation (“I/P”), pursuant to an Agreement and Plan of Merger, dated as of March 13, 2012 (the “Merger Agreement”), by and among Vringo, I/P and VIP Merger Sub, Inc., a wholly-owned subsidiary of Vringo (“Merger Sub”). Pursuant to the Merger Agreement, I/P became a wholly-owned subsidiary of Vringo through a merger of I/P with and into Merger Sub (which was renamed Innovate/Protect, Inc.), and the former stockholders of I/P received shares of Vringo that constituted a majority of the outstanding shares of Vringo.

As a result, the Merger has been accounted for as a reverse acquisition under which I/P was considered the acquirer of Vringo. As such, the financial statements of I/P are treated as the historical financial statements of the combined company, with the results of Vringo being included from July 19, 2012.

All references in this Quarterly Report on Form 10-Q to “we,” “us” and “our” refer to Vringo, Inc., a Delaware corporation, and its consolidated subsidiaries for periods after the closing of the Merger, and to I/P and its consolidated subsidiaries for periods prior to the closing of the Merger unless the context requires otherwise.

Note 1—General

Vringo, Inc., together with its consolidated subsidiaries (the “Company” or “Vringo”), is engaged in the innovation, licensing and protection of intellectual property worldwide. Vringo's intellectual property portfolio consists of over 500 patents and patent applications covering telecom infrastructure, internet search and mobile technologies. The Company’s patents and patent applications have been developed internally and acquired from third parties. Vringo operates a global platform for the distribution of mobile social applications and services it develops.

On July 19, 2012, Vringo, Inc., a Delaware corporation (“Vringo” or “Legal Parent”), closed a merger transaction (the “Merger”) with Innovate/Protect, Inc., a privately held Delaware corporation (“I/P”), pursuant to an Agreement and Plan of Merger, dated as of March 13, 2012 (the “Merger Agreement”), by and among Vringo, I/P and VIP Merger Sub, Inc., a wholly-owned subsidiary of Vringo (“Merger Sub”). Pursuant to the Merger Agreement, I/P became a wholly-owned subsidiary of Vringo through a merger of I/P with and into Merger Sub, and the former stockholders of I/P received shares of Vringo that constituted a majority of the outstanding shares of Vringo.

Because former I/P stockholders owned, immediately following the Merger, approximately 67.61% of the combined company on a fully diluted basis, and as a result of certain other factors, I/P was deemed to be the acquiring company for accounting purposes and the transaction was accounted for as a reverse acquisition in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). Accordingly, the Company’s financial statements for periods prior to the Merger reflect the historical results of I/P and not Vringo’s historical results prior to the Merger, and the Company’s financial statements for all periods from July 19, 2012 reflect the results of the combined company. Unless specifically noted otherwise, as used throughout these consolidated financial statements, the term “Company” refers to the combined company after the Merger, and the business of I/P before the Merger. The terms I/P and Vringo refer to such entities’ standalone businesses prior to the Merger.

I/P (a development stage company) was incorporated on June 8, 2011 (“Inception”) under the laws of Delaware as Labrador Search Corporation.

Based on current operating plans, the current resources of the Company are expected to be sufficient for at least the next twelve months. The Company may choose to raise additional funds in connection with any future acquisition of additional intellectual property assets, operating businesses or other assets that it may choose to pursue. There can be no assurance, however, that any such opportunities will materialize. Moreover, any potential financing would likely be dilutive to the Company’s stockholders.

As of March 31, 2013, approximately $448 and $31 of the Company's net assets were located in Israel and Germany, respectively. In addition, the Company owns patents issued outside of the United States.

Note 2—Significant Accounting and Reporting Policies

(a) Basis of presentation

The accompanying consolidated financial statements include the accounts of the Legal Parent, I/P and their wholly-owned subsidiaries, and are presented in accordance with instructions to Form 10-Q and, therefore, do not include all disclosures necessary for a complete presentation of financial position, results of operations, and cash flows in conformity with U.S. generally accepted accounting principles. These financial statements should be read in conjunction with the consolidated financial statements and related notes for the year ended December 31, 2012. The results of operations for the three month period ended March 31, 2013 are not necessarily indicative of the results that may be expected for the entire fiscal year or for any other interim period. All significant intercompany balances and transactions have been eliminated in consolidation. These financial statements include the results of operations of I/P and its subsidiaries for all periods presented, with the results of operations of the Legal Parent and its subsidiaries for the period from July 19, 2012 (the effective date of the Merger). Moreover, equity amounts, as well as net loss per common share, presented for comparative periods differ from those previously presented by I/P, due to application of accounting requirements applicable to a reverse acquisition.

(b) Development stage enterprise

The Company’s principal activities to date have been focused on enforcement and development of its intellectual property, as well as on the research and development of its products. To date, the Company has not generated any significant revenues from its planned principal operations. Accordingly, the Company’s financial statements are presented as those of a development stage enterprise.

Note 2—Significant Accounting and Reporting Policies—(cont’d) 

(c) Translation into U.S. dollars

The currency of the primary economic environment in which the operations of the Company are conducted is the U.S. dollar ("U.S. $" or “$”). Therefore, the U.S. dollar has been determined to be the Company's functional currency. Post-Merger, the Company conducted significant transactions in foreign currencies (primarily the New Israeli Shekels ("NIS") and Euro). These are recorded at the exchange rate as of the transaction date. All exchange gains and losses from remeasurement of monetary balance sheet items denominated in non-dollar currencies are reflected as finance expense in the statement of operations, as they arise.

	NIS		Euro
At March 31, 2013		3.648		0.782
At December 31, 2012		3.733		0.759
Average exchange rate for the period from July 19, 2012 through March 31, 2013		3.846		0.775
Average exchange rate for the period from January 1, 2013 through March 31, 2013		3.708		0.757

(d) Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results may differ from such estimates. Significant items subject to such estimates and assumptions include valuation of assets assumed and liabilities incurred as part of the Merger, useful lives of the Company’s tangible and intangible assets, valuation of its short-term investments and the October 2012 Warrants (as defined in Note 7) and derivative warrants, valuation of its share-based compensation, deferred tax assets and liabilities, income tax uncertainties and other contingencies.

(e) Cash and cash equivalents

The Company invests its surplus cash in commercial paper, money market deposits and money market funds with financial institutions. The Company has established guidelines relating to diversification and maturities of its investments, in order to minimize credit risk and maintain high liquidity of funds. For the purpose of these financial statements, all highly liquid investments with original maturities of three months or less are considered cash equivalents. Cash and cash equivalents include $740 and $0 invested in commercial papers with an initial term (upon purchase by the Company) of less than three months at March 31, 2013 and December 31, 2012, respectively.

(f) Short-term investments

Currently, short-term investment securities as of March 31, 2013 and December 31, 2012, in the total amount of $3,120 and $0, respectively, consist of investment in commercial paper. The Company classified its investments as held-to-maturity. Held-to-maturity debt securities are those debt securities in which the Company has the ability and intent to hold the security until maturity. Held-to-maturity debt securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts. Premiums and discounts on debt securities are amortized or accreted over the life of the related held-to-maturity security as an adjustment to yield using the effective-interest method. Such amortization and accretion is included in the “non-operating income” line item in the Consolidated Statements of Operations. Dividend and interest income are recognized when earned.

(g) Net loss per share data

Basic net loss per share is computed by dividing the net loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing the net loss for the period by the weighted-average number of shares of common stock plus dilutive potential common stock considered outstanding during the period. Such dilutive shares consist of incremental shares that would be issued upon exercise of the Company’s derivative warrants (see also Note 7). The table below presents the computation of basic and diluted net losses per common share:

In June 2011, the Company’s subsidiary acquired patents from Lycos, Inc. The gross carrying amount of those patents is comprised of the original purchase price of $3,200 and $196 of associated patent acquisition costs.

In August 2012, the Company purchased from Nokia Corporation a portfolio consisting of various patents and patent applications. The portfolio encompasses a broad range of technologies relating to telecom infrastructure, including communication management, data and signal transmission, mobility management, radio resources management and services. The total consideration paid for the portfolio was $22,000. In addition, the Company capitalized certain costs related to the acquisition of patents in the total amount of $548. Under the terms of the purchase agreement, to the extent that the gross revenue generated by such portfolio exceeds $22,000, the Company is obligated to pay a royalty of 35% of such excess. The Company has not recorded any amounts in respect of this contingent consideration, as both the amounts of future potential revenue, if any, and the timing of such revenue cannot be reliably established.

In October 2012, the Company’s subsidiary entered into a patent purchase agreement. As partial consideration, the Company issued 160,600 shares of common stock to the seller with the fair value of $750. In addition, under the terms of the purchase agreement, 20% of the gross revenue collected will be payable to the seller as a royalty. The Company has not recorded any amounts in respect of this contingent consideration, as both the amounts of future potential revenue, if any, and the timing of such revenue cannot be reliably established.

During the three month periods ended March 31, 2013 and 2012, the Company recorded amortization expense of $1,255 and $155, respectively. During the period from Inception through March 31, 2013, total amortization expense of $4,038 was recorded. Estimated amortization expense for each of the five succeeding years, based upon intangible assets owned at March 31, 2013 is as follows:

Note 4—Fair Value Measurements

The Company measures fair value in accordance with ASC 820-10, “Fair Value Measurements and Disclosures” (formerly SFAS 157, “Fair Value Measurements”). ASC 820-10 clarifies that fair value is an exit price, representing the amount that would be received by selling an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, ASC 820-10 establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

Level 2 Inputs: Inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant inputs are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The Company measures its derivative liabilities at fair value. The Special Bridge Warrants, Conversion Warrants, Preferential Reload Warrants and Series 1 Warrants (as they are defined in Note 7) are classified within Level 3 because they are valued using the Black-Scholes-Merton and the Monte-Carlo models (as all of these warrants include down-round protection clauses), which utilize significant inputs that are unobservable in the market.

The following table presents the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2013 and December 31, 2012, aggregated by the level in the fair-value hierarchy within which those measurements fall:

Note 4—Fair Value Measurements—(cont’d)

In addition to the above, the Company’s financial instruments at March 31, 2013 and December 31, 2012 consisted of cash, cash equivalents, short-term investments, accounts receivable, accounts payable and long term deposits. The carrying amounts of all the aforementioned financial instruments approximate fair value. The following table summarizes the changes in the Company’s liabilities measured at fair value using significant unobservable inputs (Level 3) during the period from Inception through March 31, 2013. No assets, nor liabilities, were valued using Level 3 inputs for the period ended March 31, 2012:

Valuation processes for Level 3 Fair Value Measurements

Fair value measurement of the derivative liability on account of Special Bridge Warrants, Conversion Warrants, Preferential Reload Warrants and Series 1 Warrants (as defined in Note 7) fall within Level 3 of the fair value hierarchy. The fair value measurements are evaluated by management to ensure that changes are consistent with expectations of management based upon the sensitivity and nature of the inputs.

Description	Valuation technique	Unobservable inputs	Range
Special Bridge Warrants, Conversion Warrants, Preferential Reload Warrants and the Series 1 Warrants	Black-Scholes-Merton and the Monte-Carlo models	Volatility		56.48% – 58.10%
		Risk free interest rate		0.25% – 0.60%
		Expected term, in years		1.75 – 4.30
		Dividend yield		0%
		Probability and timing of down-round triggering event		15% occurrence in December 2013

Sensitivity of Level 3 measurements to changes in significant unobservable inputs

The inputs to estimate the fair value of the Company’s derivative warrant liability are the current market price of the Company’s common stock, the exercise price of the warrant, its remaining expected term, the volatility of the Company’s common stock market price, the Company’s estimations regarding the probability and timing of a down-round protection triggering event and the risk-free interest rate. Significant changes in any of those inputs in isolation can result in a significant change in the fair value measurement. Generally, a positive change in the market price of the Company’s common stock, and an increase in the volatility of the Company’s shares of common stock, or an increase in the remaining term of the warrant, or an increase of a probability of a down-round triggering event would each result in a directionally similar change in the estimated fair value of the Company’s warrants and thus an increase in the associated liability and vice-versa. An increase in the risk-free interest rate or a decrease in the positive differential between the warrant’s exercise price and the market price of the Company’s shares of common stock would result in a decrease in the estimated fair value measurement of the warrants and thus a decrease in the associated liability. The Company has not, nor plans to, declare dividends on its common stock, and thus, there is no change in the estimated fair value of the warrants due to the dividend assumption.

Note 5 – Business Combination

On July 19, 2012, I/P consummated the Merger with the Legal Parent, as also described in Note 1. The consideration consisted of various equity instruments, including: shares of common stock, preferred stock, options and warrants. The purpose of the Merger was to increase the combined company's intellectual property portfolio and array of products, to gain access to capital markets, and for other reasons. Upon completion of the Merger, (i) all then outstanding 6,169,661 common stock shares of I/P, par value $0.0001 per share, were exchanged for 18,617,569, shares of the Company’s common stock, par value $0.01 per share, and (ii) all then outstanding shares of Series A Convertible Preferred Stock of I/P, par value $0.0001 per share, were exchanged for 6,673 shares of the Legal Parent’s Series A Convertible Preferred Stock, par value $0.01 per share, which shares were convertible into 20,136,445 shares of common stock of the Legal Parent. In addition, the Legal Parent issued to the holders of I/P capital stock an aggregate of 15,959,838 warrants to purchase an aggregate of 15,959,838 shares of the Company’s common stock with an exercise price of $1.76 per share. The Company recorded such warrants as a derivative long-term liability in the total amount of $21,954 (see also Note 4). In addition, all outstanding and unexercised options to purchase I/P common stock, whether vested or unvested, were converted into 41,178 options to purchase the Company’s common stock. Immediately following the completion of the Merger, the former stockholders of I/P owned approximately 55.04% of the outstanding common stock of the combined company (or 67.61% of the outstanding shares of the Company’s common stock, calculated on a fully diluted basis), and the Legal Parent’s stockholders prior to the Merger owned approximately 44.96% of the outstanding common stock of the combined company (or 32.39% of the outstanding shares of its common stock calculated on a fully diluted basis). For accounting purposes, I/P was identified as the accounting “acquirer”, as it is defined in FASB Topic ASC 805. The total purchase price of $75,654 was allocated to the assets acquired and liabilities assumed of the Legal Parent. Registration and issuance cost, in the total amount of $463, was recorded against the additional paid-in capital.

Current assets, net of current liabilities		2,586
Long-term deposit		8
Property and equipment		124
Technology		10,133
Goodwill		65,965

Measurement of consideration:
Fair value of vested stock options granted to employees, management and consultants, classified as equity		7,364
Fair value of outstanding warrants granted by the Legal Parent prior to the Merger, classified as equity		10,079
Fair value of Vringo shares of common stock and vested $0.01 options granted to employees, management and consultants		58,211
Total estimated purchase price		75,654

The fair values of the identified intangible assets were estimated using an income approach. Under the income approach, an intangible asset’s fair value is equal to the present value of future economic benefits to be derived from ownership of the asset. Indications of value are developed by discounting future net cash flows to their present value at market-based rates of return. The goodwill recognized as a result of the acquisition is primarily attributable to the value of the workforce and other intangible asset arising as a result of name, operational synergies, products, and similar factors which could not be separately identified. The useful life of the intangible assets for amortization purposes was determined considering the period of expected cash flows used to measure the fair value of the intangible assets adjusted as appropriate for the entity-specific factors including legal, regulatory, contractual, competitive economic or other factors that may limit the useful life of intangible assets. As of March 31, 2013, according to ASC 805, the purchase price allocation is still provisional. The Company expects the existing value of its goodwill to change upon completion of a study regarding its total net tax loss carryforwards utilizable for tax purposes, performed by a third party expert. Goodwill recognized is not deductible for income tax purposes. Had the acquisition taken place on June 8, 2011 (Inception), the revenue in the consolidated statement of operations and the consolidated net loss would have been as follows:

	Three month period ended March 31, 2012					Cumulative from Inception to March 31, 2013
	Revenue		Net Loss			Revenue		Net Loss
Total amount		106		(7,762	)		1,074		(52,580	)

The pro forma adjustment consists of amortization of acquired technology. The amortization, net, for the three month period ended March 31, 2012 would have been $247. The amortization, net, for the period from Inception through March 31, 2013 would have been $1,789. The above pro forma disclosure excludes the possible impact of valuation of equity and derivative instruments valued in connection with the Merger.

Note 6—Series A Convertible Preferred Stock

Prior to the Merger, I/P was authorized to issue up to 10,000,000* shares of preferred stock, par value $0.0001, of which 6,968* shares of preferred stock were designated as Series A Convertible Preferred Stock with such rights and preferences designated in the relevant Certificate of Designations (the “Series A Preferred Stock”). In June 2011, I/P issued 6,968* shares of Series A Preferred Stock to Hudson Bay for $1,800. The Series A Preferred Stock had a liquidation preference of $1,250 per share and was otherwise convertible, at the option of the holder, into 6,968,000* shares of I/P’s common stock at a conversion price of $1 per common share received, subject to adjustment for anti-dilution and other corporate events. In 2012, prior to the Merger, 295 shares of Series A Convertible Preferred Stock were converted into 295,000* shares of common stock of I/P.

Prior to the Merger, the Series A Convertible Preferred Stock was classified as mezzanine equity, because of certain cash redemption triggering events which were outside the control of the Company. Upon the Merger, the remaining 6,673* Series A Preferred stock shares were exchanged for 6,673 shares of equity-classified new Series A Convertible Preferred Stock, $0.01 par value (“New Series A Convertible Preferred Stock”), issued by Legal Parent to former stockholders of I/P, as part of the Merger. The shares of New Series A Convertible Preferred Stock were convertible into 20,136,445 shares of the Legal Parent’s shares of common stock and were classified as equity, as a cash-based redemption event is only triggered by events which are fully in the control of the Company. In August 2012, following the consummation of the Merger, all outstanding shares of New Series A Convertible Preferred Stock were converted.

* Share amounts were not retrospectively restated to reflect Vringo’s equity instruments after the Merger.

(b) Equity Incentive Plan

In August 2011, I/P adopted its 2011 Equity and Performance Incentive Plan (the “I/P 2011 Plan”). The I/P 2011 Plan provided for the issuance of stock options and restricted stock to the Company’s directors, employees and consultants. Terminated, expired or forfeited grants may be reissued under the I/P 2011 Plan. The number of shares available under I/P 2011 Plan was subject to adjustments for certain changes. Following the Merger with the Legal Parent, the I/P 2011 Plan was assumed by the Company’s 2012 Employee, Director and Consultant Equity Incentive Plan (“2012 Plan”).

On July 19, 2012, following the Merger with the Legal Parent, the Company’s stockholders approved the 2012 Plan, replacing the existing 2006 Stock Option Plan of the Legal Parent, and the remaining 9,100,000 authorized shares thereunder were cancelled. The 2012 Plan was approved in order to ensure full compliance with legal and tax requirements under U.S. law. The number of shares subject to the 2012 Plan is the sum of: (i) 15,600,000 shares of common stock, which constitutes 6,500,000 new shares and 9,100,000 previously authorized but unissued shares under the 2006 Stock Option Plan and (ii) any shares of common stock that are represented by awards granted under the Legal Parent’s 2006 Stock Option Plan that are forfeited, expired or are cancelled without delivery of shares of common stock or which result in the forfeiture of shares of common stock back to the Company, or the equivalent of such number of shares after the administrator, in its sole discretion, has interpreted the effect of any stock split, stock dividend, combination, recapitalization or similar transaction in accordance with the 2012 Plan; provided, however, that no more than 3,200,000 shares shall be added to the 2012 Plan. As of March 31, 2013, 3,722,750 shares were available for future grants under the 2012 Plan.

For the three month periods ended March 31, 2013 and 2012, the Company recorded total stock compensation expense of $3,094 and $84, respectively. Cumulatively from Inception through March 31, 2013, the Company has recorded stock compensation expense of $11,655.

The Company cumulatively did not create tax benefits related to its stock-based compensation due to a full valuation allowance in the U.S.

(d) Warrants

The following table summarizes information about warrant activity for the three month period ended March 31, 2013:

Outstanding at March 31, 2013		18,769,114		$	3.12		$0.94 – $5.06

The Company’s outstanding warrants consisted of the following:

(a) Series 1 and Series 2 Warrants

As part of the Merger, on July 19, 2012, the Legal Parent issued to I/P’s stockholders 8,299,116 warrants at an exercise price of $1.76 per share and contractual term of 5 years (“Series 1 Warrant”). These warrants bear down-round protection clauses and as a result, they were classified as a long-term derivative liability and recorded at fair value. In addition, I/P’s stockholders received another 7,660,722 warrants at an exercise price of $1.76 per share and contractual term of 5 years (“Series 2 Warrant”). As the Series 2 Warrants do not have down-round protection clauses, they were classified as equity. During the three month period ended March 31, 2013, 48,957 Series 1 Warrants and 45,190 Series 2 Warrants were exercised. From Inception and through March 31, 2013, 4,704,056 Series 1 Warrants and 1,326,060 Series 2 Warrants were exercised.

(b) Conversion Warrants, Special Bridge Warrants and Reload Warrants

On July 19, 2012, the date of the Merger, Legal Parent’s outstanding warrants included: (i) 148,390 derivative warrants, at an exercise price of $0.94 per share, with a remaining contractual term of 2.44 years (the “Special Bridge Warrants”); (ii) 101,445 derivative warrants, at an exercise price of $0.94 per share, with a remaining contractual term of 2.44 years (the “Conversion Warrants”); (iii) 887,330 derivative warrants, at an exercise price of $1.76 per share, with a remaining contractual term of 4.55 years (the “Preferential Reload Warrants”); and (iv) 814,408 warrants, classified as equity, at an exercise price of $1.76 per share, with a remaining contractual term of 4.55 years (the “non-Preferential Reload Warrants”). During the three month period ended March 31, 2013, none of these warrants were exercised. From Inception and through March 31, 2013, 169,520 non-Preferential Reload Warrants and 726,721 Preferential Reload Warrants were exercised.

(c) Initial Public Offering Warrants

Upon completion of its initial public offering, the Legal Parent issued 4,784,000 warrants at an exercise price of $5.06 per share. These warrants are publicly traded and are exercisable until June 21, 2015, at an exercise price of $5.06 per share. As of March 31, 2013, all of these warrants were outstanding and classified as equity.

(d) October 2012 Warrants

On October 12, 2012, the Company entered into an agreement with certain of its warrant holders, pursuant to which, on October 23 and 24, 2012, the holders exercised in cash 3,721,062 of their outstanding warrants, with an exercise price of $1.76 per share. In exchange, the Company granted such warrant holders unregistered warrants of the Company to purchase an aggregate of 3,000,000 shares of the Company’s common stock, par value $0.01 per share, at an exercise price of $5.06 per share (the “October 2012 Warrants”). The contractual life of these warrants is 2.66 years and because such warrants do not bear any down-round protection clauses they were classified as equity instruments. October 2012 Warrants were valued using the following assumptions: volatility: 68.1%, share price: $3.50-$3.77, risk free interest rate: 0.724% and dividend yield: 0%. The fair value of warrants issued in exchange for the exercise of the Company’s derivative warrants was accounted for as an inducement, therefore an amount of $2,883, was recorded as a non-operating expense. As of March 31, 2013, all October 2012 warrants were outstanding.

The Company retains the services of law firms that specialize in intellectual property licensing, enforcement and patent law. These law firms are retained on an hourly fee, monthly fee, project fee, contingent fee, or blended fee basis. In a contingency fee arrangement, law firms are paid a scaled percentage of any negotiated fees, settlements or judgments awarded, based on how and when the fees, settlements or judgments are obtained.

On November 6, 2012, the Company received a verdict in its case against AOL, Inc., Google, Inc., IAC Search & Media, Inc., Gannett Company, Inc. and Target Corporation (collectively, "Defendants") with respect to the Defendants' infringement of the asserted claims of U.S. Patent Nos. 6,314,420 and 6,775,664 (collectively, the "IPE Patents"). After finding that the asserted claims of the IPE Patents were not invalid, and infringed by the Defendants, the jury found that reasonable royalty damages should be based on a "running royalty", and that the running royalty rate should be 3.5%. The jury also found that the following sums of money, if paid now in cash, would reasonably compensate I/P Engine for the Defendants’ past infringement as follows: Google: $15,800, AOL: $7,943, IAC: $6,650, Gannett: $4, Target: $99. Motions by I/P Engine for awards of pre-judgment interest, post-judgment interest, supplemental damages and post-judgment royalties, are pending in U.S. District Court. I/P Engine and Defendants have filed notices of appeal with the Court of Appeals for the Federal Circuit. In response to a request by Google, Inc., the IPE Patents are being reexamined by the U.S. Patent and Trademark Office (see also Note 9 (b)). On January 31, 2013, I/P Engine filed an action asserting infringement of the IPE Patents in the United States District Court, Southern District of New York, against Microsoft Corporation. According to certain scaled fee agreements, I/P Engine will pay between 15% and 20% of any recovery to professional service providers. As of March 31, 2013, the Company did not record any revenue, nor a liability for any potential, contingent, legal fees, related to these litigations, as timing of collection, if any, or the amounts due to it, cannot be determined.

From October 2012 through March 31, 2013, the Company’s subsidiaries filed patent infringement lawsuits against the subsidiaries of ZTE Corporation in the United Kingdom, France and Germany. Should the Company be deemed the losing party in any of its applications to the court in the UK, it may be held responsible for a substantial percentage of the defendant’s legal fees for the relevant application or for the litigation. As a result, the Company placed a guarantee to ensure the payment of a potential liability, which the defendants estimated to be approximately $2,900. However, should the Company be successful on any court applications or the entire litigation, ZTE would be responsible for a substantial percentage of its legal fees. In addition, the Company will grant additional guarantees, as necessary, in connection with its commenced proceedings against ZTE in Europe.

In July 2012, the Company signed a rental agreement for its new headquarters in New York. According to the new agreement, the Company shall pay an annual fee of approximately $137 (subject to certain adjustments). The Company’s subsidiary in Israel leases an office space for a period of up to four years (including options to extend the terms of the lease). According to the agreement, the subsidiary in Israel shall pay an annual fee of approximately $72 (in NIS, subject to certain adjustments). Rent expense for operating leases and automobiles for the three month periods ended March 31, 2013 and 2012, and the cumulative period from Inception until March 31, 2013, was $53, $8 and $227, respectively.

Future minimum lease payments under non-cancelable operating leases for office space and cars, as of March 31, 2013, are as follows:

	Amount
Period ending December 31,
2013 (nine months ending December 31, 2013)		177
2014		178

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

(U.S. $ in thousands)

Note 9—Risks and Uncertainties

(a)	New legislation, regulations or rulings that impact the patent enforcement process or the rights of patent holders, could negatively affect the Company’s current business model. For example, limitations on the ability to bring patent enforcement claims, limitations on potential liability for patent infringement, lower evidentiary standards for invalidating patents, increases in the cost to resolve patent disputes and other similar developments could negatively affect the Company’s ability to assert its patent or other intellectual property rights.
(b)	As part of the Company’s ongoing legal proceedings, the validity and/or enforceability of the patents is often challenged in a court or administrative proceeding. Several of the Company’s patents are being challenged in several jurisdictions. In particular, on March 15, 2012, Google submitted a request to the USPTO for ex parte reexamination of U.S. Patent No. 6,314,420. On July 18, 2012, the USPTO issued a determination ordering a reexamination. On September 25, 2012, the USPTO issued a first, non-final office action where it adopted the rejections proposed by Google. The Company's response was filed on November 26, 2012. A final, appealable office action maintaining the rejections was mailed on May 3, 2013. The Company has until July 3, 2013 to file a response or a notice of appeal to the Patent Trial and Appeal Board. On November 28, 2012, Google submitted a request to the USPTO for ex parte reexamination of U.S. Patent No. 6,775,664. On January 17, 2013, the USPTO issued a determination ordering a reexamination, but found that three of the prior art references identified by Google were not considered prior art to the 6,775,664 patent. Google filed a second reexamination request of that patent on February 8, 2013. On March 7, 2013, the USPTO issued a determination ordering a reexamination based on the three additional references. The Company believes its patents are both valid and enforceable.
(c)	Financial instruments which potentially subject the Company to significant concentrations of credit risk consist principally of cash, cash equivalents, short-term investments and accounts receivable. The Company maintains its cash, cash equivalents and short-term investments with various major financial institutions. These major financial institutions are located in the United States, Germany and Israel, and the Company’s policy is designed to limit exposure to any one institution.
(d)	A portion of the Company’s expenses are denominated in NIS, British Pound and Euro. If the value of the U.S. dollar weakens against the value of these currencies, there will be a negative impact on the Company’s operating costs. In addition, the Company is subject to the risk of exchange rate fluctuations to the extent it holds monetary assets and liabilities in these currencies.

Overview

We were incorporated in Delaware on January 9, 2006 and commenced operations during the first quarter of 2006. In March 2006, we formed a wholly-owned subsidiary, Vringo (Israel) Ltd., for the primary purpose of providing research and development services, as detailed in the intercompany service agreement. On July 19, 2012, I/P merged with us through an exchange of equity instruments of I/P for those of Vringo. The Merger was accounted for as a reverse acquisition under which I/P was considered the accounting acquirer of Vringo. As such, the financial statements of I/P are treated as the historical financial statements of the combined company, with the results of Vringo included from July 19, 2012. I/P was incorporated in Delaware on June 8, 2011, originally as Labrador Search Corporation, and holds two wholly-owned subsidiaries: I/P Engine Inc., which was formed in Virginia on June 14, 2011, originally as Smart Search Labs Inc., which operates for the purpose of realizing economic benefits of intellectual property, and I/P Labs, Inc., which was incorporated in Delaware on June 8, 2011, originally as Scottish Terrier Capital Inc., which operates for the purpose of acquiring and developing patented technologies and intellectual property. In August 2012, we formed two wholly-owned subsidiaries, incorporated in Delaware: Vringo Labs, Inc. which operates for the purpose of acquiring and developing patented technologies and intellectual property, and Vringo Infrastructure, Inc., which operates for the purpose of realizing economic benefits mainly from telecommunications infrastructure patents. Vringo Infrastructure, Inc. acquired assets from Nokia Corporation (“Nokia”) upon its formation, as further described below. In addition, on October 18, 2012, we formed a wholly-owned subsidiary in Germany, Vringo Germany GmbH, for the purpose of innovating, developing, and monetizing mobile technology and intellectual property in Germany.

Our business strives to innovate, acquire, license and protect intellectual property worldwide. Our attempts are focused on identification, acquisition and generation of economic benefits of intellectual property assets. We plan to continue to further expand our portfolio of intellectual property assets through acquisition and internal development of new technologies. We intend to monetize our intellectual property assets through a variety of value enhancing initiatives, including, but not limited to:

• licensing,

• strategic partnerships, and

• litigation.

We are still a development stage company. From the inception of I/P (June 8, 2011) (“Inception”) to date, we have raised approximately $96,013,000. These amounts have been used to finance our operations, as until now, we have not yet generated any significant revenues. From Inception through March 31, 2013, we recorded losses of approximately $35,559,000 and net cash outflow from operations of approximately $20,868,000. Our average monthly cash burn rate from operations for the three month period ended March 31, 2013 was approximately $1,624,000.

Intellectual Property

Upon Inception in June 2011, I/P acquired its initial patent assets from Lycos, Inc (“Lycos”) through its wholly-owned subsidiary, I/P Engine. Such assets were comprised of eight patents relating to information filtering and search technologies. As one means of realizing the value of the patents acquired from Lycos, on September 15, 2011, I/P initiated (through I/P Engine) litigation in the United States District Court, Eastern District of Virginia, against AOL Inc. (“AOL”), Google, Inc. (“Google”), IAC Search & Media, Inc. (“IAC”), Gannett Company, Inc. (“Gannett”), and Target Corporation (“Target”) (collectively, the “Defendants”) for infringement regarding two of the patents acquired from Lycos (U.S. Patent Nos. 6,314,420 and 6,775,664) (collectively the “Patents”). The case number is 2:11 CV 512-RAJ/FBS. The court docket for the case, including the parties’ briefs, is publicly available on the Public Access to Court Electronic Records website (“PACER”), www.pacer.gov, which is operated by the Administrative Office of the U.S. Courts.

Trial commenced on October 16, 2012, and the case was submitted to the jury on November 1, 2012. On November 6, 2012, the jury unanimously returned a verdict as follows: (i) I/P Engine had proven by a preponderance of the evidence that the Defendants infringed the asserted claims of the patents; and (ii) Defendants had not proven by clear and convincing evidence that the asserted claims of the patents are invalid by anticipation. The jury also found certain specific facts related to the ultimate question of whether the patents are invalid as obvious. Based on such facts, on November 20, 2012, the court issued a ruling that the patents-in-suit were not obvious. The jury found that reasonable royalty damages should be based on a "running royalty", and that the running royalty rate should be 3.5%. The jury also found that the following sums of money, if paid now in cash, would reasonably compensate I/P Engine for the Defendants past infringement: Google: $15,800,000, AOL: $7,943,000, IAC: $6,650,000, Gannett: $4,322, Target: $98,833. Motions by I/P Engine for awards of pre-judgment interest, post-judgment interest, and supplemental damages, and post-judgment royalties, are pending in U.S. District Court. I/P Engine and Defendants have filed appeals with the Court of Appeals for the Federal Circuit. The docket numbers are 13-1307 and 13-1311. The parties' filings are available on PACER.

On March 15, 2012, Google submitted a request to the USPTO for ex parte reexamination of U.S. Patent No. 6,314,420, one of the two patents-in-suit. The request was deposited on March 16, 2012 and was assigned Control No. 90/009,991. On July 18, 2012, the USPTO issued a determination ordering a reexamination. On September 25, 2012, the USPTO issued a first, non-final office action where it adopted the rejections proposed by Google. Our response was filed on November 26, 2012. Since then, we conducted an examiner interview and filed an Interview Summary on February 22, 2013. A final, appealable office action maintaining the rejections was mailed on May 3, 2013. We currently have until July 3, 2013 to file a response or a notice of appeal to the Patent Trial and Appeal Board.

On November 28, 2012, Google submitted a request to the USPTO for ex parte reexamination of U.S. Patent No. 6,775,664, the other of the two patents-in-suit. The request was assigned Control No. 90/012,722. On January 17, 2013, the USPTO issued a determination ordering a reexamination, but found that three of the prior art references identified by Google were not considered prior art to the 6,775,664 patent. In an effort to have those three prior art references considered in a reexamination request of U.S. Patent No. 6,775,664, Google filed a second reexamination request of that patent on February 8, 2013. On March 7, 2013, the USPTO issued a determination ordering a reexamination based on the three additional references. The reexamination was assigned Control No. 90/012,791. It is expected that the two reexaminations of U.S. Patent No. 6,775,664 will be merged into a single proceeding. Further action from the USPTO is thereafter expected, including either a Notice of Intent to Issue a Reexamination Certificate affirming the patentability of all subject claims or a First Non-Final Office Action.

To further realize the value of the patents acquired from Lycos, on January 31, 2013, I/P Engine filed an action asserting infringement of U.S. Patent Nos. 6,314,420 and 6,775,664 in the United States District Court, Southern District of New York, against Microsoft Corporation. The case number is 1:13 CV 688-JGK.

Infrastructure Patents

On August 9, 2012, we entered into a patent purchase agreement with Nokia Corporation ("Nokia"), pursuant to which Nokia sold us a portfolio consisting of over 500 patents and patent applications worldwide, including over 100 issued United States patents. We agreed to compensate Nokia with a cash payment and certain ongoing rights in revenues generated from the patent portfolio. The portfolio encompasses technologies relating to telecom infrastructure and handsets, including communication management, data and signal transmission, mobility management, radio resources management and services. Declarations have been filed by Nokia indicating that 31 of the 124 patent families acquired may be essential to wireless communications standards. Standards represented in the portfolio are commonly known as 2G, 2.5G, 3G and 4G and related technologies and include GSM, WCDMA, T63, T64, DECT, LTE, and SAE. The purchase price for the portfolio was $22,000,000, and in addition we capitalized acquisition costs of $548,000. To the extent that the gross revenue (as defined in the purchase agreement) generated by such portfolio exceeds $22,000,000, a royalty of 35% of such excess would be payable to Nokia. The $22,000,000 cash payment was made to Nokia on August 10, 2012. The purchase agreement provides that Nokia and its affiliates will retain a non-exclusive, worldwide and fully paid-up license (without the right to grant sublicenses) to the portfolio for the sole purpose of supplying (as defined in the purchase agreement) Nokia’s products. The purchase agreement also provides that if we bring a proceeding against Nokia or its affiliates within seven years, Nokia shall have the right to re-acquire the patent portfolio for a nominal amount. Further, if we either sell to a third party any assigned essential cellular patent, or more than a certain portion of the other assigned patents (other than in connection with a change of control of our company), or file an action against a telecom provider to enforce any of the assigned patents (other than in response to any specified action filed by a telecom provider against us or our affiliate) which action is not withdrawn after notice from Nokia, then we will be obligated to pay to Nokia a substantial impairment payment.

As one of the means of realizing the value of the patents on telecom infrastructure, our wholly-owned subsidiaries, Vringo Infrastructure, Inc. (“Vringo Infrastructure”) and Vringo Germany GmbH (“Vringo Germany”) have filed a number of suits in European jurisdictions alleging infringement of certain European patents.

On October 5, 2012, Vringo Infrastructure, filed a suit in the UK High Court of Justice, Chancery Division, Patents Court, alleging infringement of European Patents (UK) 1,212,919; 1,166,589; and 1,808,029. ZTE (UK) Ltd.’s formal response to the complaint was received on November 19, 2012 and included a counterclaim for invalidity of the patents in suit. Vringo Infrastructure responded to the defense on January 16, 2013. Vringo Infrastructure filed a further UK suit on December 3, 2012, alleging infringement of European Patents (UK) 1,221,212; 1,330,933; and 1,186,119. ZTE (UK) Ltd.’s response to this claim was received on February 27, 2013 and included a counterclaim for invalidity of the patents in suit. Vringo Infrastructure’s reply was filed on March 20, 2013. The UK complaints allege that ZTE’s cellular network elements fall within the scope of all six patents, and ZTE’s GSM/UMTS multi-mode wireless handsets also fall within the scope of at least the 1,808,029 patent. Declarations have been filed at the European Telecommunications and Standards Institute (ETSI) that cover all the patent applications from which the patents in suit are derived. A case management conference where among other matters, the schedule for the UK lawsuits will be set, is anticipated in the first week of June 2013.

Germany has a split-infringement system where patent infringement cases are heard in district courts of general jurisdiction and nullity cases (where the validity of patents is adjudicated) are heard in a different proceeding in the Federal Patents Court. Appeals from the district court and the Patents Court are heard by distinct appellate courts. The final appeals from those appeal courts are combined and heard together in German Federal Supreme Court. Infringement actions are typically decided by the trial court within 8 to 13 months. Nullity cases are typically decided by the trial court within 18 to 22 months. If the district court finds a patent infringed, absent specific factors, it will generally issue an injunction. Where there is a pending nullity action and the accused infringer has not sufficiently rebutted the asserted patent’s presumption of validity, the district court will generally issue an injunction upon payment of a security. Where the presumption of validity has been sufficiently rebutted, the district court will generally stay proceedings pending the outcome of the nullity case if infringement is established at trial.

On November 15, 2012, Vringo Germany filed a suit in the Mannheim Regional Court in Germany, alleging infringement of European Patent (DE) 1,212,919. ZTE Corporation and ZTE Deutschland GmbH formally responded to the complaint on February, 15, 2013. The lawsuit was expanded to include a second patent on February 21, 2013, alleging infringement of European Patent (DE) 1,186,119. At the Mannheim Court’s request a consolidated trial is scheduled to be held on October 15, 2013. On February 14, 2013, ZTE filed its first defensive infringement pleading with respect to European Patent (DE) 1,186,119. The Mannheim Court has set the due date for Vringo Germany’s reply brief on May 31, 2013 and ZTE’s rejoinder brief on August 30, 2013. No further briefing before trial is currently anticipated.

To date, ZTE has not made an Orange Book offer with respect to European Patent (DE) 1,186,119. Under German law, where a defendant alleges: (a) plaintiff has a dominant position under the relevant competition (a/k/a anti-trust) laws, for example, because of plaintiff’s assertion of a patent that is essential to a technical standard, and (b) plaintiff has failed to offer a license under fair, reasonable and non-discriminatory terms (FRAND), and if the defendant’s allegation is accepted by the Court, the Court may decide not to grant an injunction. It is a condition of this defense in Germany that the defendant must make a binding, unconditional offer to the plaintiff to conclude a license on FRAND terms and stay bound by that offer. Furthermore, the Orange Book offer must be such that its rejection by the plaintiff would amount to an abuse of a dominant position. Finally, defendant must behave like a licensee and provide regular royalty reports and remit payment to plaintiff or pay a sufficient amount of the royalties for prior infringement into escrow.

On February 15, 2013, ZTE filed a nullity suit with respect to European Patent (DE) 1,212,919 in the Federal Court, Munich, Germany, alleging invalidity of the patent. Vringo’s responsive pleading is due on July 25, 2013. We anticipate a trial in the nullity suit to occur in the second half of 2014.

In November and December 2012, ZTE Corporation initiated invalidity proceedings in China against Chinese Patents ZL00806049.5; ZL 00812876.6; and ZL200480044232.1, the Chinese equivalents of European Patents 1,212,919; 1,166,589; and 1,808,029. Vringo Infrastructure has begun defending these actions by filing responses in January and February 2013. The oral hearing for ZL200480044232.1 occurred on April 10, 2013 and is still pending. An oral hearing for ZL00806049.5 occurred on May 9, 2013 and is still pending. A hearing for ZL00812876.6 has not yet been scheduled.

On March 29, 2013 Vringo Infrastructure, Inc., filed a patent infringement lawsuit in France against ZTE Corporation, China and its French subsidiary, ZTE France SASU, in the Tribunal de Grande Instance de Paris, alleging infringement of the French part of European Patents 1,186,119 and 1,221,212 by ZTE devices, which are believed to fall within the scope of these patents. Vringo Infrastructure filed the lawsuit based on particular information uncovered during a seizure to obtain evidence of infringement, known as a saisie-contrefaçon, which was executed at two of ZTE's facilities in France. The case has been filed with the tribunal de grande instance de Paris for it to allocate the case to a division of the 3rd chamber (specializing in IP matters). A first scheduling conference has not yet been set.

Mobile Social Applications

We have developed a platform for the distribution of mobile applications. We continue to develop this platform and integrate it with mobile operators and content providers. Our product, which encompasses a suite of mobile and PC-based tools, enables users to create, download and share video ringtones and provides our business partners with a consumer-friendly and easy-to-integrate monetization platform. The standard revenue model for our video ringtone service offered through the carriers is a subscription-based model where users pay a monthly fee for access to our service and additional fees for premium content. Our Vringo video ringtone mobile application also functions as a standalone direct-to-consumer offering. Our free version has been released as an advertisement-supported application on the Google Play marketplace and is available in markets where we have not entered into commercial arrangements with carriers or other partners. As of May 9, 2013, we have commercial video ringtone services with nine carriers and partners.

Our Facetones® social ringtone application generates social visual ringtone content automatically by aggregating and displaying a user’s friends’ pictures from social networks and then displaying the pictures as a video ringtone, as well as a video ringback tone. These ringtones do not replace, but rather enhance, standard ringtone and ringback tones with relevant, current social content that is visually displayed. The product is available to consumers on several operating systems, most notably Android and is delivered in various configurations, with a variety of monetization methods. As of March 31, 2013, the Facetones® app reached over 2,000,000 total downloads across all platforms. In Q1 2013, the Facetones® app generated over 15,000,000 mobile impressions. Facetones® is offered directly to consumers via leading mobile application stores and download sites where both freemium and ad-supported versions are available. Our revenue model is based on proceeds received from advertising networks, as well as from related development projects and potential payment of royalties. We have developed five separate versions of Facetones, including our most recent partnership with Nokia for the Asha Full Touch 311 devices.

Merger

The accompanying consolidated financial statements include the accounts of I/P, Legal Parent and their wholly-owned subsidiaries, and are presented in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"). All significant intercompany balances and transactions have been eliminated in consolidation. These financial statements include the results of operations of I/P and subsidiaries for all periods presented, with the results of operations of the Legal Parent and its subsidiaries for the period from July 19, 2012 (the effective date of the Merger) through March 31, 2013. Moreover, common stock amounts presented for comparative periods differ from those previously presented by I/P, due to application of accounting requirements applicable to a reverse acquisition.

Stock Exchange

On April 18, 2013, we provided written notice to the NYSE MKT LLC that the Company intends to transfer the listing of the Company’s common stock and warrants from the NYSE MKT LLC to the NASDAQ Capital Market, and withdraw the listing and registration of the common stock and warrants from the NYSE MKT LLC. The common stock and the warrants have been authorized for listing on the NASDAQ Capital Market. Our common stock and warrants ceased trading on the NYSE MKT LLC at the close of business on April 29, 2013, and began trading on the NASDAQ Capital Market on April 30, 2013.

Our Strategy

We innovate, acquire, license and protect intellectual property worldwide. We continually strive to expand our portfolio of intellectual property both through acquisition and development. Our goal is to partner with inventors who own the rights to compelling technologies. As of today, we manage an intellectual property portfolio consisting of over 500 patents and patent applications, covering telecom infrastructure, internet search, and mobile technologies. These patents and patent applications have been developed internally and acquired from third parties. To date we have filed 24 patent applications and have three issued patents in the United States and one notice of allowance in Europe. We believe that licenses to certain of our patents will be of interest to other application developers, infrastructure providers and manufacturers, and hardware manufacturers.

We seek to purchase all of, or interests in, intellectual property in exchange for cash and/or securities of our company and/or interests in the monetization of those assets. Our revenue from this business can be generated through licensing and litigation efforts. We engage in robust due diligence and a principled risk underwriting process to evaluate the merits and potential value of these assets. We seek to structure the terms of our acquisitions in a manner that will achieve the highest risk-adjusted returns possible. We believe that our capital resources and potential access to capital, together with the experience of our management team and board, will allow us to assemble a portfolio of quality assets with short and long-term revenue opportunities.

We believe that our core technology and business relationships will allow us to distribute applications and services through mobile operators, handset makers, and application storefronts. Our video ringtone platform remains the primary source of revenues among our mobile products and we continue to develop business for this product with mobile operators and content providers. Our solution, which encompasses a suite of mobile and PC-based tools, enables users to create, download and share video ringtones and provides our business partners with a consumer-friendly and easy-to-integrate monetization platform. Our Vringo video ringtone mobile app also functions as a standalone direct-to-consumer offering. As of May 9, 2013, we have commercial video ringtone services with seven carriers and partners. Separately, we seek to continue to expand the distribution of our free, ad-supported, mobile application.

Revenue

Revenue from subscription services, software development and intellectual property is recognized if collection is probable, persuasive evidence of an arrangement exists, the sales price is fixed or determinable and delivery of the service has been rendered. Revenues from non-refundable up-front fees are recognized according to the guidance in SAB Topic 13.A.3.f. As these up-front fees relate to the hosting of the service over a period of the contract, we recognize these up-front fees over the life time of the contract. According to ASU 2009-13, Revenue Recognition (Topic 605), we use management's best estimate of selling price for individual elements in multiple-element arrangements, where other sources of evidence are unavailable.

Cost of revenue

Cost of revenues mainly include the costs and expenses incurred in connection with our patent licensing and enforcement activities, contingent legal fees paid to external patent counsels, other patent-related legal expenses paid to external patent counsel, licensing and enforcement related research, consulting and other expenses paid to third parties, the amortization of patent-related acquisition costs and of the acquired technology, the value to which was allocated upon consummation of the Merger. Cost of revenue also includes third party expenses directly related to providing our service in launched markets. Cost of revenue does not include expenses related to product development, integration and support, as these costs are included in research and development.   

Research and development expenses

Research and development expenses consist primarily of the cost of our development and operations personnel, as well as of the cost of outsourced development, server and support activities needed to maintain our operations. 

Marketing, general and administrative expenses

Marketing, general and administrative expenses include the cost of marketing, management and administrative personnel, public and investor relations, advertising, overhead/office cost and various professional fees, as well as insurance, depreciation and amortization. 

24

Non-operating income (expenses)

Non-operating income (expenses) includes transaction gains (losses) from foreign exchange rate differences, interest on deposits, bank charges, as well as fair value adjustments of derivative liabilities on account of the Preferential Reload Warrants, Special Bridge Warrants, Series 1 Warrants and the Conversion Warrants. The value of such derivative liabilities is highly influenced by assumptions used in its valuation, as well as by the Company’s stock price at the period end (revaluation date). 

Income taxes

Our effective tax rate differs from the statutory federal rate primarily due to differences between income and expense recognition prescribed by income tax regulations and generally accepted accounting principles. We utilize different methods and useful lives for depreciating and amortizing property and equipment and different methods and timing for certain expenses. Furthermore, permanent differences arise from certain income and expense items recorded for financial reporting purposes but not recognizable for income tax purposes. As part of the Merger purchase price allocation, we recorded a deferred tax liability in connection with the acquired technology. This deferred tax liability was offset by a deferred tax asset in the same amount. The deferred tax asset in respect of the remaining tax loss carryforwards has been offset by a valuation allowance as in our opinion it is more likely than not that the tax loss carryforwards will not be utilized in the foreseeable future. No valuation allowance has been provided for the deferred tax assets of the Israeli subsidiary, since as of March 31, 2013 they are more likely than not to be realized. 

Our subsidiary in Israel generates net taxable income from services it provides to us. The subsidiary in Israel charges us for research, development, certain management and other services provided to us, plus a profit margin on such costs, which is currently 8%. In the zone where the production facilities of the subsidiary in Israel are located, the statutory tax rate is 12.5% in 2013 and expected to be 12.5% in 2014, and 12% in 2015 and thereafter.

Results of Operations

Three month period ended March 31, 2013 compared to the three month period ended March 31, 2012 and the development stage period (cumulative from Inception through March 31, 2013)

Revenue

	Three months ended March 31,						Cumulative from Inception through March 31,
	2013		2012		Change		2013
Revenue	$	65,000	$	—	$	65,000	$	434,000

During the three month period ended March 31, 2013, we recorded total revenues of $65,000, compared to $0 in the three month period ended March 31, 2012. The revenue recorded in the first quarter of 2013 consisted solely of subscription and content based revenue generated by legacy Vringo business, whereas the comparative figures refer to pre-Merger I/P.

From Inception through March 31, 2013, revenue amounted to $434,000. The recognized revenue consisted of: (i) subscription and content sales based revenue of $234,000, which represents legacy Vringo revenue from July 19, 2012, the date of the Merger, (ii) revenue from a development project with Nokia of $100,000, completed in 2012, and (iii) proceeds from partial settlement with AOL in the total amount of $100,000.

On November 6, 2012, we received a verdict in a patent infringement action against AOL, Inc., Google, Inc., IAC Search & Media, Inc., Gannett Company, Inc. and Target Corporation (collectively, "Defendants") with respect to the Defendants' infringement of the asserted claims of U.S. Patent Nos. 6,314,420 and 6,775,664, and that Defendants had not proven by clear and convincing evidence that the asserted claims of the patents are invalid by anticipation. The jury also found certain specific facts related to the ultimate question of whether the patents are invalid as obvious. Based on such facts, on November 20, 2012, the U.S. District Court issued a ruling that the patents-in-suit were not invalid as obvious, and the clerk entered the Court's final judgment. The jury found that reasonable royalty damages should be based on a "running royalty", and that the running royalty rate should be 3.5%. The jury also found that the following sums of money, if paid now in cash, would reasonably compensate I/P Engine for the Defendants past infringement as follows: Google: $15,800,000, AOL: $7,943,000, IAC: $6,650,000, Gannett: $4,000 Target: $99,000. Motions by I/P Engine for awards of pre-judgment interest, post-judgment interest, and supplemental damages, and post-judgment royalties, are pending in U.S. District Court. I/P Engine and Defendants have filed notices of appeal with the Court of Appeals for the Federal Circuit.

On January 31, 2013, I/P Engine filed an action asserting infringement of the IPE Patents in the United States District Court, Southern District of New York, against Microsoft Corporation. As of March 31, 2013, we did not record any revenue related to this litigation, as timing of collection, if any, or the amounts due to it, cannot be determined.

We seek to generate revenue through licensing or litigation, when required, which may be resolved through a settlement or collection. We also intend to continue to expand our planned operations through acquisitions and monetization of additional patents, other intellectual property or operating business. In particular, following the incorporation of our subsidiary in Germany and the acquisition of a patent portfolio from Nokia, we intend to expand our intellectual property monetization efforts worldwide. In October and November 2012, we filed litigation against the UK and German subsidiaries of ZTE, respectively. In March 2013 we filed litigation against the French subsidiary of ZTE, with a goal of achieving a positive verdict or settlement, including, potentially, a licensing arrangement on terms beneficial to us. In addition, in January 2013, we filed an action asserting infringement of two of the patents acquired from Lycos, against Microsoft Corporation. In addition we expect to maintain a portion of our future revenues from mobile applications and services. We anticipate that our legal proceedings may continue for several years and may require significant expenditures for legal fees and other expenses. Disputes regarding the assertion of patents and other intellectual property rights are highly complex and technical.

Cost of revenue

	Three months ended March 31,						Cumulative from Inception through March 31,
	2013		2012		Change		2013
Cost of services provided	$	27,000	$	—	$	27,000	$	74,000
Amortization of intangibles	$	1,255,000	$	155,000	$	1,100,000	$	4,038,000
Operating legal	$	5,399,000	$	1,096,000	$	4,303,000	$	16,642,000
Total	$	6,681,000	$	1,251,000	$	5,430,000	$	20,754,000

During the three month period ended March 31, 2013, our cost of revenue was $6,681,000, which represents an increase of $5,430,000 (434%) from cost of revenue recorded for the three month period ended March 31, 2012. The increase in cost of revenue, compared to the first quarter of 2012, was mainly related to increased amortization expenses related to patents acquired ($839,000, compared to $155,000 in the first quarter of 2012), as well as due to amortization of acquired Vringo technology, the value to which was allocated upon consummation of the Merger ($416,000, compared to $0 in the first quarter of 2012). In addition, we incurred significant consulting and litigation costs, ($5,105,000, compared to $1,096,000 in the first quarter of 2012), mainly related to the recently commenced legal proceedings against ZTE, and non-cash, stock-based compensation costs ($294,000, compared to $0 in the first quarter of 2012). Finally, the increase of $27,000 in cost of revenue relates to cost of Vringo mobile products, recorded pursuant to the Merger with I/P.

From Inception through March 31, 2013, cost of revenue expenses amounted to $20,754,000. Of this amount, $74,000 was attributed to the cost of mobile services, $817,000 to non-cash, stock-based compensation expense, $1,179,000 was attributed to amortization of the acquired technology, $15,825,000 was attributed to operating legal expenses, mainly related to our patent litigations, and $2,859,000 was attributed to patent amortization.

We expect that our cost of revenue will increase over time, as we diversify the portfolio of our products and increase our intellectual property. With the goal of monetizing our intellectual property, we intend to commence a new licensing and litigation campaigns which are expected to be costly.

Research and development 

	Three months ended March 31,						Cumulative from Inception through March 31,
	2013		2012		Change		2013
Research and development	$	826,000	$	—	$	826,000	$	2,566,000

During the three month period ended March 31, 2013, our research and development expense amounted to $826,000. This is primarily comprised of: (i) development team cost of $467,000, and (ii) related non cash, stock-based compensation cost of $243,000. These expenses mainly relate to post-Merger cost of the legacy Vringo research and development center in Israel.

From Inception through March 31, 2013, research and development expenses, in the total amount of $2,566,000, recorded following the Merger with I/P, consist primarily of the cost of our development team of $1,277,000 and related stock-based compensation cost $934,000.

We anticipate that research and development costs incurred in connection with our core mobile services may decrease over time. In particular, in March 2013, we reduced research and development personnel. In addition, we now focus our efforts towards finding new technologies and local intellectual property. We expect that following the above-mentioned reorganization, should we seek to introduce new products, or new business opportunities, such as a merger or acquisition relating to our technology, our research and development costs would be expected to increase.

Marketing, general and administrative

	Three months ended March 31,						Cumulative from Inception through March 31,
	2013		2012		Change		2013
Marketing, general and administrative	$	4,137,000	$	616,000	$	3,521,000	$	16,207,000

During the three month period ended March 31, 2013, marketing, general and administrative expenses increased by $3,521,000 (or 572%), to $4,137,000, from $616,000 recorded during the three month period ended March 31, 2012. Marketing, general and administrative expenses increased mostly due to an increase in payroll expense ($671,000, compared to $141,000 recorded in the first quarter of 2012), as well as due to an increase in stock-based compensation expense ($2,557,000, compared to $84,000 recorded in the first quarter of 2012), and increased corporate legal expenses ($134,000, compared to $58,000 recorded in the first quarter of 2012), offset by a decrease in merger and acquisition expenses ($12, compared to $172,000 recorded in the first quarter of 2012).

From Inception through March 31, 2013, marketing, general and administrative expenses amounted to $16,207,000. Of that amount, $2,473,000 was attributed to salaries and related expenses, $9,904,000 was attributed to non-cash stock-based compensation, $297,000 was attributed to merger and acquisition activity and $1,899,000 was attributed to various professional fees.

26

We expect our marketing, general and administrative expenses to increase, as our expenses will incorporate full costs of the new management, on a post-Merger basis, as well as increased administration, rent, office, accounting, legal and insurance costs. New merger and acquisition opportunities, should such arise, may also significantly increase our marketing, general and administrative costs.

Non-operating income (expense), net 

	Three months ended March 31,									Cumulative from Inception through March 31,
	2013			2012			Change			2013
Non-operating income (expense), net	$	(369,000	)	$	(4,000	)	$	(365,000	)	$	3,605,000

Following the Merger, our non-operating income (expenses), net, included mainly the impact of changes in fair value of derivative warrants, the fair value of which is highly affected by our share price at the measurement date. Consequently, during the three month period ended March 31, 2013, we recorded an expense of $376,000 due to the increase of our share price, compared to the share price at December 31, 2012.

We expect that our non-operating income (expenses), net, will remain highly volatile, as we may choose to fund our operations through additional financing. In particular, non-operating income (expenses) will be affected by the adjustments to fair value of our derivative instruments. Fair value of these derivative instruments depends on variety of assumptions, such as estimations regarding volatility, triggering of down-round protection and estimated future share price. An estimated increase in the price of our common stock increases the value of the warrants and thus results in a loss on our statement of operations. In addition, increase in estimated probability of a down-round protection, increases the value of the warrants and again results in a loss on our statement of operations. Also see Notes 4 and 7 to the accompanying financial statements.

Income tax expense

	Three months ended March 31,						Cumulative from Inception through March 31,
	2013		2012		Change		2013
Income tax expense	$	16,000	$	—	$	16,000	$	71,000

During the three month ended March 31, 2013, we recorded income tax expense in the total amount of $16,000, compared to $0 recorded in the three month period ended March 31, 2012. In general, current taxes on income are mainly due to taxable profits generated by our subsidiary in Israel, as a result of the intercompany cost plus agreement between us and the subsidiary in Israel, whereby the subsidiary in Israel performs development and other services for us and is reimbursed for its expenses plus 8% profit. For financial statements purposes, these profits are eliminated upon consolidation.

As of December 31, 2012, the Legal Parent and I/P had approximately $55,728,000 in aggregate total net tax loss carryforwards ("NOL") for U.S. federal state and local purposes expiring 20 years from the respective tax years to which they relate (beginning with 2006 for the Legal Parent and 2011 for I/P). The Tax Reform Act of 1986 imposed substantial restrictions on the utilization of NOL and tax credits in the event of an ownership change of a corporation. Thus, in accordance with Internal Revenue Code, Section 382, our initial public offering, financing activities, as well as the Merger, may significantly limit our ability to utilize such NOL’s and credit carryforwards. We are currently in the process of completing a full Section 382 study that will allow us to determine the amounts we will be able to utilize for tax purposes in the future.

We file our tax returns in the U.S. federal jurisdiction, as well as in various state and local jurisdictions. Vringo has open tax assessments for the years 2009 through 2012. As of March 31, 2013, all tax assessments for I/P are still open. The Israeli subsidiary files its income tax returns in Israel. As of March 31, 2013, the Israeli subsidiary has open tax assessments for the years 2009 through 2012.

As part of the Merger purchase price allocation, we recorded a deferred tax liability in connection with the acquired technology (see also Note 5 to the accompanying financial statements). This deferred tax liability was offset by a deferred tax asset in the same amount. The deferred tax asset in respect of the remaining tax loss carryforwards has been offset by a valuation allowance as in our opinion it is more likely than not that the tax loss carryforwards will not be utilized in the foreseeable future. No valuation allowance has been provided for the deferred tax assets of the Israeli subsidiary since as of March 31, 2013, they are more likely than not to be realized. 

We expect that our tax expense in Israel to decrease in 2013, as the scope of services provided to us is expected to decrease, mainly due to reduction in operating and support personnel, which is expected to take effect in the second quarter of 2013. We also expect our income tax expenses in the U.S. to increase in 2013, partially due to the potential increase in revenues, as well as due to increase in local taxes influenced by the increased equity and our total assets.

Liquidity and Capital Resources

As of March 31, 2013, we had a cash balance of $49,128,000 and $48,528,000 in net working capital. The decrease of $7,832,000 in our cash balance from December 31, 2012, was mainly due to $3,120,000 invested in commercial paper (classified as short-term investments) and net cash used by us in our business operations, in the total amount of approximately $4,872,000, offset by $174,000 received from the exercise of options and warrants.

During the three month period ended March 31, 2013, 94,147 warrants to purchase an aggregate of 94,147 shares of our common stock, at an exercise price of $1.76 per share, were exercised by our warrant holders, pursuant to which we received an additional $165,000. In addition, 533,562 options and RSUs, collectively, to purchase 533,562 shares of our common stock, issued to employees, directors and management, were exercised. As a result, we received an additional $9,000.

As of May 8, 2013, we had approximately $49,298,000 in cash, cash equivalents and short-term investments. Based on current operating plans, we expect to have sufficient funds for at least the next twelve months. In addition, we may choose to raise additional funds in connection with potential acquisitions of patent portfolios or other intellectual property assets that we may pursue. There can be no assurance, however, that any such opportunities will materialize.

Cash flows

	Three months ended March 31,									Cumulative from Inception through March 31,
	2013			2012			Change			2013
Net cash used in operating activities	$	(4,872,000	)	$	(1,227,000	)	$	(3,645,000	)	$	(20,868,000	)
Net cash used in investing activities	$	(3,140,000	)	$	(5,000	)	$	(3,135,000	)	$	(26,021,000	)
Net cash provided by financing activities	$	174,000		$	—		$	174,000		$	96,013,000

Operating activities

During the three month periods ended March 31, 2013 and 2012, net cash used in operating activities totaled $4,872,000 and $1,227,000, respectively. The $3,645,000 increase in net cash used in operating activities was mainly due to increased litigation costs, as well as an increase in our in-house staff, hired since the Merger in July 19, 2012.

We expect our net cash used in operating activities to increase due to further development of our business, development of our products and enhancement of our intellectual property. As we move towards greater revenue generation, we expect that these amounts will be offset over time by collection of revenue.

Investing activities

During the three month periods ended March 31, 2013 and 2012, net cash used in investing activities totaled $3,140,000 and $5,000, respectively. The increase in cash used in investing activities, in the total amount of $3,135,000, was primarily due to the investment in commercial paper classified as short-term investments, in the total amount of $3,120,000. Fixed asset purchases during the three month period ended March 31, 2013, amounted to $28,000 compared to $5,000 for the three month period ended March 31, 2012, mainly due to post-Merger relocation of our headquarters.

We expect that net cash used in investing activities will increase as we intend to continue to acquire additional intellectual property assets and invest surplus cash, according to our investment policy.

Financing activities

 During the three month period ended March 31, 2013, net cash provided by financing activities totaled $174,000, which relates to funds received from the exercise of warrants and options in the total amount of $165,000 and $9,000, respectively. No cash was used, nor provided, in/by financing activities in the three month period ended March 31, 2012.

A significant portion of our issued and outstanding warrants are currently “in the money” and the shares of common stock underlying such warrants held by non-affiliates are freely tradable, with the potential of up to $19,127,937 of additional incoming funds. We may choose to raise additional funds in connection with any acquisition of patent portfolios or other intellectual property assets that we may pursue. There can be no assurance, however, that any such opportunity will materialize, and moreover, any such financing would likely be dilutive to our current stockholders.

Future operations 

We are currently pursuing several potential strategic partners and have identified patent portfolios, other intellectual property assets and operating businesses that we may wish to acquire. In addition, we are continuing to explore further opportunities for strategic business alliances. However, there can be no assurance that any such opportunities will be consummated.

Off-Balance Sheet Arrangements

On October 8, 2012, our subsidiary filed a patent infringement lawsuit against a subsidiary of ZTE Corporation in the United Kingdom. Should we be deemed the losing party in any of our applications to the court in the UK, we may be held responsible for a substantial percentage of the defendant’s legal fees for the relevant application or for the litigation. As a result, we placed a guarantee of approximately $2,900,000 to ensure this contingent liability. However, should we be successful on any court applications or the entire litigation, ZTE would be responsible for a substantial percentage of our legal fees. In addition, we expect that additional guarantee placements may be necessary in connection with additional proceedings in Europe.

We have no obligations, assets or liabilities which would be considered off-balance sheet arrangements. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements.

Critical Accounting Estimates

While our significant accounting policies are more fully described in the notes to our audited consolidated financial statements for the year ended December 31, 2012, we believe the following accounting policies to be the most critical in understanding the judgments and estimates we use in preparing our consolidated financial statements. 

29

Goodwill and Intangible Assets

We accounted for the Merger in accordance with FASB Topic ASC 805 ”Business Combinations” and for identified goodwill and technology in accordance with FASB Topic ASC 350 ”Intangibles - Goodwill and Other”. Additionally, we review our long-lived assets for recoverability in accordance with FASB Topic ASC 360 “Property, Plant and Equipment”.

The identification and valuation of intangible assets and the determination of the estimated useful lives at the time of acquisition are based on various valuation methodologies including reviews of projected future cash flows. The use of alternative estimates and assumptions could increase or decrease the estimated fair value of our goodwill and other intangible assets, and potentially result in a different impact to our results of operations. Further, changes in business strategy and/or market conditions may significantly impact these judgments thereby impacting the fair value of these assets, which could result in an impairment of the goodwill and acquired intangible assets.

In addition, at March 31, 2013, our purchase price allocation is still provisional, as existing estimations are subject to change, in certain future events. See also Note 5 to the accompanying financial statements.

We evaluate our long-lived tangible and intangible assets for impairment in accordance with FASB Topic ASC 350 ”Intangibles - Goodwill and Other” and FASB Topic ASC 360 “Property, Plant and Equipment” whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Goodwill is subject to an annual test for impairment, or for impairment testing up on the occurrence of triggering events. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. While we use available information to prepare our estimates and to perform impairment evaluations, the completion of annual impairment tests requires significant management judgments and estimates.

Valuation of Financial Instruments

On July 19, 2012, the date of the Merger, Vringo’s outstanding warrants included: (i) 148,390 Special Bridge Warrants, at an exercise price of $0.94, with an expected remaining term of 2.44 years; (ii) 101,445 Conversion Warrants, at an exercise price of $0.94, with an expected remaining term of 2.44 years; (iii) 887,330 Preferential Reload Warrants, at an exercise price of $1.76, with an expected remaining term of 4.55 years; and (iv) 814,408 non-Preferential Reload Warrants, at an exercise price of $1.76, with an expected remaining term of 4.55 years. During the three month period ended March 31, 2013, none of these warrants were exercised.Following the Merger and through December 31, 2012, 169,520 non-Preferential Reload Warrants and 726,721 Preferential Reload Warrants were exercised.

As part of the Merger, on July 19, 2012, we issued to I/P’s stockholders 8,299,116 warrants at an exercise price of $1.76 and expected term of 5 years (“Series 1 Warrant”). These warrants bear down-round protection clauses, as a result, they were classified as a long-term derivative liability and recorded at fair value. In addition, I/P’s stockholders received another 7,660,722 warrants at an exercise price of $1.76 and expected term of 5 years (“Series 2 Warrant”). As these warrants do not have down-round protection clauses, they were classified as equity. During the three month period ended March 31, 2013, 48,957 Series 1 Warrants and 45,190 Series 2 Warrants were exercised. Following the Merger and through December 31, 2012, 4,655,099 Series 1 Warrants and 1,280,870 Series 2 Warrants were exercised. The following table represents the assumptions, valuation models and inputs used, as of March 31, 2013:

	Valuation	Unobservable
Description	Technique	Inputs	Range
Special Bridge Warrants, Conversion Warrants,	Black-Scholes-Merton and the Monte-Carlo models	Volatility		56.48% – 58.10%
Preferential Reload Warrants and the Series 1 Warrants		Risk free interest rate		0.25% – 0.60%
		Expected term, in years		1.75 – 4.30
		Dividend yield		0%
		Probability and timing of down-round triggering event		15% occurrence in December 2013

Had we made different assumptions about the risk-free interest rate, volatility, the impact of the down-round provision, or the estimated time that the abovementioned warrants will be outstanding before they are ultimately exercised, the recorded expense, our net loss and net loss per share amounts could have been significantly different.

Accounting for Stock-based Compensation

We account for stock-based awards under ASC 718, “Compensation—Stock Compensation”, which requires measurement of compensation cost for stock-based awards at fair value on the date of grant and the recognition of compensation over the service period in which the awards are expected to vest. In addition, for options granted to consultants, FASB ASC 505-50, “Equity-Based Payments to Non Employees” is applied. Under this pronouncement, the measurement date of the option occurs on the earlier of counterparty performance or performance commitment. The grant is revalued at every reporting date until the measurement date. The estimation of stock-based awards that will ultimately vest requires judgment, and to the extent actual results differ from our estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised. We consider various factors when estimating expected forfeitures, including historical experience. Actual results may differ substantially from these estimates.

We determine the fair value of stock options granted to employees, directors and consultants using the Black-Scholes-Merton and the Monte-Carlo (for grants that include market conditions) valuation models, those require significant assumptions regarding the expected stock price volatility, the risk-free interest rate and the dividend yield, and the estimated period of time option grants will be outstanding before they are ultimately exercised. Due to insufficient history, we estimate our expected stock volatility incorporating historical stock volatility from comparable companies.

30

These option pricing models utilize various inputs and assumptions, which are highly subjective. Had we made different assumptions about the risk-free interest rate, volatility, or the estimated time that the options will be outstanding before they are ultimately exercised, the recorded expense, our net loss and net loss per share amounts could have been significantly different. Had we used different assumptions, our results may have been significantly different.

Accounting for Income Taxes

As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves management estimating our actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not more likely than not, we must establish a valuation allowance. Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. As part of the Merger purchase price allocation, we recorded a deferred tax liability in connection with the acquired technology (see also Note 5 to the accompanying financial statements). This deferred tax liability was offset by a deferred tax asset in the same amount. The deferred tax asset in respect of the remaining tax loss carryforwards has been offset by a valuation allowance. Our lack of earnings history and the uncertainty surrounding our ability to generate U.S. taxable income prior to the expiration of such deferred tax assets were the primary factors considered by management in establishing the valuation allowance.

ASC 740, “Income Taxes”, prescribes how a company should recognize, measure, present and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return. Additionally, for tax positions to qualify for deferred tax benefit recognition under ASC 740, the position must have at least a “more likely than not” chance of being sustained upon challenge by the respective taxing authorities, which criteria is a matter of significant judgment.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer (principal executive officer) and our Chief Financial Officer (principal financial officer), evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2013. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2013, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective for the reasons set forth below.

Changes in Internal Controls

As of December 31, 2012, our management has identified a material weakness in our disclosure controls and procedures relating to insufficient controls in connection with valuation and accounting for equity, debt and derivative instruments. In January 2013, we have added an additional member to our accounting department and in addition enhanced our proficiency of the professional literature on these subjects and broadened external oversight. As a result of these steps we have remediated the material weakness in our disclosure controls and procedures.

Part II— OTHER INFORMATION

Item 1. Legal Proceedings.

Search Patents

Upon inception in June 2011, I/P acquired its initial patent assets from Lycos, Inc (“Lycos”) through its wholly-owned subsidiary, I/P Engine. Such assets were comprised of eight patents relating to information filtering and search technologies. As one means of realizing the value of the patents acquired from Lycos, on September 15, 2011, I/P initiated (through I/P Engine) litigation in the United States District Court, Eastern District of Virginia, against AOL Inc. (“AOL”), Google, Inc. (“Google”), IAC Search & Media, Inc. (“IAC”), Gannett Company, Inc. (“Gannett”), and Target Corporation (“Target”) (collectively, the “Defendants”) for infringement regarding two of the patents acquired from Lycos (U.S. Patent Nos. 6,314,420 and 6,775,664) (collectively the “Patents”). The case number is 2:11 CV 512-RAJ/FBS. The court docket for the case, including the parties’ briefs, is publicly available on the Public Access to Court Electronic Records website (“PACER”), www.pacer.gov, which is operated by the Administrative Office of the U.S. Courts.

Trial commenced on October 16, 2012, and the case was submitted to the jury on November 1, 2012. On November 6, 2012, the jury unanimously returned a verdict as follows: (i) I/P Engine had proven by a preponderance of the evidence that the Defendants infringed the asserted claims of the patents; and (ii) Defendants had not proven by clear and convincing evidence that the asserted claims of the patents are invalid by anticipation. The jury also found certain specific facts related to the ultimate question of whether the patents are invalid as obvious. Based on such facts, on November 20, 2012, the court issued a ruling that the patents-in-suit were not obvious. The jury found that reasonable royalty damages should be based on a "running royalty", and that the running royalty rate should be 3.5%. The jury also found that the following sums of money, if paid now in cash, would reasonably compensate I/P Engine for the Defendants past infringement: Google: $15,800,000, AOL: $7,943,000, IAC: $6,650,000, Gannett: $4,322, Target: $98,833.

Motions by I/P Engine for awards of pre-judgment interest, post-judgment interest, and supplemental damages, and post-judgment royalties, are pending in U.S. District Court. I/P Engine and Defendants have filed appeals with the Court of Appeals for the Federal Circuit. The docket numbers are 13-1307 and 13-1311. The parties' filings are available on PACER.

On March 15, 2012, Google submitted a request to the USPTO for ex parte reexamination of U.S. Patent No. 6,314,420, one of the two patents-in-suit. The request was deposited on March 16, 2012 and was assigned Control No. 90/009,991. On July 18, 2012, the USPTO issued a determination ordering a reexamination. On September 25, 2012, the USPTO issued a first, non-final office action where it adopted the rejections proposed by Google. Our response was filed on November 26, 2012. Since then, we conducted an examiner interview and filed an Interview Summary on February 22, 2013. A final, appealable office action maintaining the rejections was mailed on May 3, 2013. We currently have until July 3, 2013 to file a response or a notice of appeal to the Patent Trial and Appeal Board.

On November 28, 2012, Google submitted a request to the USPTO for ex parte reexamination of U.S. Patent No. 6,775,664, the other of the two patents-in-suit. The request was assigned Control No. 90/012,722. On January 17, 2013, the USPTO issued a determination ordering a reexamination, but found that three of the prior art references identified by Google were not considered prior art to the 6,775,664 patent. In an effort to have those three prior art references considered in a reexamination request of U.S. Patent No. 6,775,664, Google filed a second reexamination request of that patent on February 8, 2013. On March 7, 2013, the USPTO issued a determination ordering a reexamination based on the three additional references. The reexamination was assigned Control No. 90/012,791. It is expected that the two reexaminations of U.S. Patent No. 6,775,664 will be merged into a single proceeding. Further action from the USPTO is thereafter expected, including either a Notice of Intent to Issue a Reexamination Certificate affirming the patentability of all subject claims or a First Non-Final Office Action.

To further realize the value of the patents acquired from Lycos, on January 31, 2013, I/P Engine filed an action asserting infringement of U.S. Patent Nos. 6,314,420 and 6,775,664 in the United States District Court, Southern District of New York, against Microsoft Corporation. The case number is 1:13 CV 688-JGK.

Infrastructure Patents

On August 9, 2012, we entered into a patent purchase agreement with Nokia Corporation ("Nokia"), pursuant to which Nokia agreed to and did sell us a portfolio consisting of over 500 patents and patent applications worldwide, including over 100 issued United States patents. We agreed to compensate Nokia with a cash payment and certain ongoing rights in revenues generated from the patent portfolio. The portfolio encompasses technologies relating to telecom infrastructure, including communication management, data and signal transmission, mobility management, radio resources management and services. Declarations have been filed by Nokia indicating that thirty-one of the 124 patent families acquired may be essential to wireless communications standards. Standards represented in the portfolio are commonly known as 2G, 2.5G, 3G and 4G and related technologies and include GSM, WCDMA, T63, T64, DECT, LTE, and SAE. The purchase price for the portfolio was $22,000,000, and in addition we capitalized acquisition costs of $548,000. To the extent that the gross revenue (as defined in the purchase agreement) generated by such portfolio exceeds $22,000,000, a royalty of 35% of such excess would be payable to Nokia. The $22,000,000 cash payment was made to Nokia on August 10, 2012. The purchase agreement provides that Nokia and its affiliates will retain a non-exclusive, worldwide and fully paid-up license (without the right to grant sublicenses) to the portfolio for the sole purpose of supplying (as defined in the purchase agreement) Nokia’s products. The purchase agreement also provides that if we bring a proceeding against Nokia or its affiliates within seven years, Nokia shall have the right to re-acquire the patent portfolio for a nominal amount. Further, if we either sell to a third party any assigned essential cellular patent, or more than a certain portion of the other assigned patents (other than in connection with a change of control of our company), or file an action against a telecom provider to enforce any of the assigned patents (other than in response to any specified action filed by a telecom provider against us or our affiliate) which action is not withdrawn after notice from Nokia, then we will be obligated to pay to Nokia a substantial impairment payment.

32

As one of the means of realizing the value of the patents on telecom infrastructure, our wholly-owned subsidiaries, Vringo Infrastructure, Inc. (“Vringo Infrastructure”) and Vringo Germany GmbH (“Vringo Germany”) have filed a number of suits in European jurisdictions alleging infringement of certain European patents.

On October 5, 2012, Vringo Infrastructure, filed a suit in the UK High Court of Justice, Chancery Division, Patents Court, alleging infringement of European Patents (UK) 1,212,919; 1,166,589; and 1,808,029. ZTE (UK) Ltd.’s formal response to the complaint was received on November 19, 2012 and included a counterclaim for invalidity of the patents in suit. Vringo Infrastructure responded to the defense on January 16, 2013. Vringo Infrastructure filed a further UK suit on December 3, 2012, alleging infringement of European Patents (UK) 1,221,212; 1,330,933; and 1,186,119. ZTE (UK) Ltd.’s response to this claim was received on February 27, 2013 and included a counterclaim for invalidity of the patents in suit. Vringo Infrastructure’s reply was filed on March 20, 2013. The UK complaints allege that ZTE’s cellular network elements fall within the scope of all six patents, and ZTE’s GSM/UMTS multi-mode wireless handsets also fall within the scope of at least the 1,808,029 patent. Declarations have been filed at the European Telecommunications and Standards Institute (ETSI) that cover all the patent applications from which the patents in suit are derived. A case management conference where among other matters, the schedule for the UK lawsuits will be set, is anticipated in the first week of June 2013.

Germany has a split-infringement system where patent infringement cases are heard in district courts of general jurisdiction and nullity cases (where the validity of patents is adjudicated) are heard in a different proceeding in the Federal Patents Court. Appeals from the district court and the Patents Court are heard by distinct appellate courts. The final appeals from those appeal courts are combined and heard together in German Federal Supreme Court. Infringement actions are typically decided by the trial court within 8 to 13 months. Nullity cases are typically decided by the trial court within 18 to 22 months. If the district court finds a patent infringed, absent specific factors, it will generally issue an injunction. Where there is a pending nullity action and the accused infringer has not sufficiently rebutted the asserted patent’s presumption of validity, the district court, will generally issue an injunction upon payment of a security. Where the presumption of validity has been sufficiently rebutted, the district court will generally stay proceedings pending the outcome of the nullity case if infringement is established at trial.

On November 15, 2012, Vringo Germany filed a suit in the Mannheim Regional Court in Germany, alleging infringement of European Patent (DE) 1,212,919. ZTE Corporation and ZTE Deutschland GmbH formally responded to the complaint on February, 15, 2013. The lawsuit was expanded to include a second patent on February 21, 2013, alleging infringement of European Patent (DE) 1,186,119. At the Mannheim Court’s request a consolidated trial is scheduled to be held on October 15, 2013. On February 14, 2013, ZTE filed its first defensive infringement pleading with respect to European Patent (DE) 1,186,119. The Mannheim Court has set the due date for Vringo Germany’s reply brief on May 31, 2013 and ZTE’s rejoinder brief on August 30, 2013. No further briefing before trial is currently anticipated.

To date, ZTE has not made an Orange Book offer with respect to European Patent (DE) 1,186,119. Under German law, where a defendant alleges: (a) plaintiff has a dominant position under the relevant competition (a/k/a anti-trust) laws, for example, because of plaintiff’s assertion of a patent that is essential to a technical standard, and (b) plaintiff has failed to offer a license under fair, reasonable and non-discriminatory terms (FRAND), and if the defendant’s allegation is accepted by the Court, the Court may decide not to grant an injunction. It is a condition of this defense in Germany that the defendant must make a binding, unconditional offer to the plaintiff to conclude a license on FRAND terms and stay bound by that offer. Furthermore, the Orange Book offer must be such that its rejection by the plaintiff would amount to an abuse of a dominant position. Finally, defendant must behave like a licensee and provide regular royalty reports and remit payment to plaintiff or pay a sufficient amount of the royalties for prior infringement into escrow.

On February 15, 2013, ZTE filed a nullity suit with respect to European Patent (DE) 1,212,919 in the Federal Court, Munich, Germany, alleging invalidity of the patent. We anticipate a trial in the nullity suit to occur in the second half of 2014.

In November and December 2012, ZTE Corporation initiated invalidity proceedings in China against Chinese Patents ZL00806049.5; ZL 00812876.6; and ZL200480044232.1, the Chinese equivalents of European Patents 1,212,919; 1,166,589; and 1,808,029. Vringo Infrastructure has begun defending these actions by filing responses in January and February 2013. The oral hearing for ZL200480044232.1 occurred on April 10, 2013 and is still pending. An oral hearing for ZL00806049.5, occurred on May 9, 2013 and is still pending. A hearing for ZL00812876.6 has not yet been scheduled.

On March 29, 2013 Vringo Infrastructure, Inc., filed a patent infringement lawsuit in France against ZTE Corporation, China and its French subsidiary, ZTE France SASU, in the Tribunal de Grande Instance de Paris, alleging infringement of the French part of European Patents 1,186,119 and 1,221,212 by ZTE devices, which are believed to fall within the scope of these patents. Vringo Infrastructure filed the lawsuit based on particular information uncovered during a seizure to obtain evidence of infringement, known as a saisie-contrefaçon, which was executed at two of ZTE's facilities in France. The case has been filed with the tribunal de grande instance de Paris for it to allocate the case to a division of the 3rd chamber (specializing in IP matters). A first scheduling conference has not yet been set.

Item 1A. Risk Factors.

The risk factors set forth below update the risk factors in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2012. In addition to the risk factors below, you should carefully consider the other risks highlighted elsewhere in this report or in our other filings with the Securities and Exchange Commission, which could materially affect our business, financial position and results of operations. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business, financial position and results of operations.

Our limited operating history makes it difficult to evaluate our current business and future prospects.

We are a development stage company and we have generated no significant revenue to date. I/P, the accounting acquirer, was incorporated in June 2011, at which time it acquired patent assets from Lycos, Inc. To date, our business focused on the assertion of these patents. Therefore, we not only have a very limited operating history, but also a limited track record in executing our business model which includes, among other things, creating, prosecuting, licensing, litigating or otherwise monetizing our patent assets. Our limited operating history makes it difficult to evaluate our current business model and future prospects.

In light of the costs, uncertainties, delays and difficulties frequently encountered by companies in the early stages of development with no operating history, there is a significant risk that we will not be able to:

• implement or execute our current business plan, or demonstrate that our business plan is sound; and/or

• raise sufficient funds in the capital markets to effectuate our long-term business plan.

If we are unable to execute any one of the foregoing or similar matters relating to our operations, our business may fail.

33

We commenced legal proceedings against the major online search engines and communications companies, and we expect such proceedings to be time-consuming and costly, which may adversely affect our financial condition and our ability to operate our business.

To license or otherwise monetize the patent assets we own, we commenced legal proceedings against the owners of online search engines and other companies (including Microsoft Corp, ZTE (UK) Ltd., AOL, Inc., Google, Inc., IAC Search & Media, Inc., Gannett Company, Inc., and Target Corporation), pursuant to which we allege that such companies infringe on one or more of our patents. Our viability is highly dependent on the outcome of these litigations, and there is a risk that we may be unable to achieve the results we desire from such litigation, which failure would harm our business to a great degree. In addition, the defendants in these litigations have substantially more resources than we do, which could make our litigation efforts more difficult.

We anticipate that legal proceedings may continue for several years and may require significant expenditures for legal fees and other expenses. Disputes regarding the assertion of patents and other intellectual property rights are highly complex and technical. Once initiated, we may be forced to litigate against others to enforce or defend our intellectual property rights or to determine the validity and scope of other parties’ proprietary rights. The defendants or other third parties involved in the lawsuits in which we are involved may allege defenses and/or file counterclaims in an effort to avoid or limit liability and damages for patent infringement. If such defenses or counterclaims are successful, they may preclude our ability to derive licensing revenue from the patents. A negative outcome of any such litigation, or one or more claims contained within any such litigation, could materially and adversely impact our business. Additionally, we anticipate that our legal fees and other expenses will be material and will negatively impact our financial condition and results of operations and may result in our inability to continue our business. Expenses are also dependent on the outcome of current proceedings. Our failure to monetize our patent assets would significantly harm our business and financial position.

While we believe that the patents we own are being infringed by certain major online search engines and communications companies, there is a risk that a court will find the patents invalid, not infringed or unenforceable and/or that the U.S. Patent Office (USPTO) will either invalidate the patents or materially narrow the scope of their claims during the course of a reexamination. In addition, even with a positive trial court verdict, the patents may be invalidated, found not infringed or rendered unenforceable on appeal. This risk may occur either presently or from time to time in connection with future litigations we may bring. If this were to occur, it would have a material adverse effect on the viability of our company and our operations.

We believe that companies infringe our patents, but recognize that obtaining and collecting a judgment against such companies may be difficult or impossible. Patent litigation is inherently risky and the outcome is uncertain. Some of the parties we believe infringe on our patents are large and well-financed companies with substantially greater resources than ours. We believe that these parties would devote a substantial amount of resources in an attempt to avoid or limit a finding that they are liable for infringing our patents or, in the event liability is found, to avoid or limit the amount of associated damages. In addition, there is a risk that these parties may file reexaminations or other proceedings with the USPTO or other government agencies in an attempt to invalidate, narrow the scope or render unenforceable the patents we own.

Moreover, in connection with any of our present or future patent enforcement actions, it is possible that a defendant may request and/or a court may rule that we violated statutory authority, regulatory authority, federal rules, local court rules, or governing standards relating to the substantive or procedural aspects of such enforcement actions. In such event, a court may issue monetary sanctions against us or our operating subsidiaries or award attorneys’ fees and/or expenses to one or more defendants, which could be material, and if we or our subsidiaries are required to pay such monetary sanctions, attorneys’ fees and/or expenses, such payment could materially harm our operating results and financial position.

In addition, it is difficult in general to predict the outcome of patent enforcement litigation at the trial or appellate level. There is a higher rate of appeals in patent enforcement litigation than standard business litigation. The defendants in any patent action we bring in the United States, including without limitation in the I/P Engine v. AOL et al. matter have filed an appeal to the Court of Appeals to the Federal Circuit and eventually may do so in the United States Supreme Court. Such appeals are expensive and time-consuming, and the outcomes of such appeals are sometimes unpredictable, resulting in increased costs and reduced or delayed revenue.

Finally, we believe that the more prevalent patent enforcement actions become, the more difficult it will be for us to license our patents without engaging in litigation. As a result, we may need to increase the number of our patent enforcement actions to cause infringing companies to license the patent or pay damages for lost royalties. This will adversely affect our operating results due to the high costs of litigation and the uncertainty of the results.

Our subsidiaries, Vringo Infrastructure Inc. (“Vringo Infrastructure”) and Vringo Germany GmbH (“Vringo Germany”), have commenced legal proceedings against ZTE (UK) Ltd., ZTE Corporation, ZTE Deutschland GmbH, and ZTE France SASU (collectively “ZTE”), and expect such litigation to be time-consuming and costly, which may adversely affect our financial position and our ability to operate our business

To license or otherwise monetize the patent assets we acquired from Nokia, Vringo Infrastructure and Vringo Germany have commenced legal proceedings against ZTE, pursuant to which, Vringo Infrastructure and Vringo Germany allege that ZTE infringe certain of Vringo Infrastructure and/or Vringo Germany’s patents. The defendant’s parent company is much larger than us and has substantially more resources, which could make our litigation efforts more difficult.

We anticipate that the above-mentioned legal proceedings may continue for several years and may require significant expenditures for legal fees and other expenses. Disputes regarding the assertion of patents and other intellectual property rights are highly complex and technical. Once initiated, Vringo Infrastructure and Vringo Germany may be forced to litigate against others to enforce or defend their intellectual property rights or to determine the validity and scope of other parties’ proprietary rights. ZTE may allege defenses and/or file counterclaims for inter alia revocation or file collateral litigations or initiate investigations in the UK or elsewhere in an effort to avoid or limit liability and damages for patent infringement. If such actions by ZTE are successful, they may preclude our ability to derive licensing revenue from the patents currently being asserted.

Additionally, we anticipate that our legal fees and other expenses will be material and will negatively impact our financial condition and results of operations and may result in our inability to continue our business. We estimate that our legal fees over the next twelve months will be significant for these enforcement actions. Expenses thereafter are dependent on the outcome of the status of the litigation. Our failure to monetize our patent assets would significantly harm our business.

34

Further, should we be deemed the losing party in any of our applications to the Court in the UK litigation or for the entire litigation, we may be held responsible for a substantial percentage of the defendant’s legal fees for the relevant application or for the litigation. These fees may be substantial. To date, ZTE has asserted that its anticipated fees in defending the UK litigation may be approximately $2,900,000. In Germany, the amount of fees payable by a losing party is determined based on one of four possible statutory levels of “value in dispute.” The value is dispute is only very loosely correlated to the actual value of any potential final settlement or license. Under the current statute, our risk is capped at €735,000 were the court to determine that the value in dispute is at the highest tier under law. In France, should we be deemed to be the losing party, it is more likely than not that we will be ordered to pay a contribution to ZTE’s attorney and expert fees. The court in France will make an assessment of winning party’s costs during the course of the proceeding on the merits, and at its discretion order the losing party to pay a portion of those costs, typically between 40-60%. As of today, we cannot estimate our potential future liability. However, should we be successful on any court applications or the entire litigation, ZTE would be responsible for a substantial percentage of our legal fees. 

In Germany, should the court order an injunction, for it to be enforced, per the statutory rates, we believe the security would be for €1,000,000 for each of the two patents asserted. The statutory rate is not correlated to any actual monetary harm ZTE may suffer from the injunction. As a result, the district court judge is entitled to increase the amount of the security.

Further, if any of the patents in suit are found not infringed or invalid, it is highly unlikely that the relevant European patents (UK) would be viewed as essential and therefore infringed by all unlicensed market participants.

It is also possible that, in light of our litigation with ZTE, it will choose to suspend or sever its Facetones® related commercial relationship with us.

We may not be able to successfully monetize the patents we have acquired from Nokia and thus we may fail to realize all of the anticipated benefits of such acquisition.

There is no assurance that we will be able to successfully monetize the patent portfolio that we have acquired from Nokia. The patents we acquired from Nokia could fail to produce anticipated benefits, or could have other adverse effects that we currently do not foresee. Failure to successfully monetize these patent assets may have a material adverse effect on our business, financial condition and results of operations.

In addition, the acquisition of the patent portfolio is subject to a number of risks, including, but not limited to the following: 

• There is a significant time lag between acquiring a patent portfolio and recognizing revenue from those patent assets, if at all. During that time lag, material costs are likely to be incurred that would have a negative effect on our results of operations, cash flows and financial position.

• The integration of a patent portfolio is a time consuming and expensive process that may disrupt our operations. If our integration efforts are not successful, our results of operations could be harmed. In addition, we may not achieve anticipated synergies or other benefits from such acquisition.

Therefore, there is no assurance that we will be able to monetize the acquired patent portfolio and recoup our investment.

We may seek to internally develop new inventions and intellectual property, which would take time and would be costly. Moreover, the failure to obtain or maintain intellectual property rights for such inventions would lead to the loss of our investments in such activities.

Members of our management team have experience as inventors. As such, part of our business may include the internal development of new inventions or intellectual property that we will seek to monetize. However, this aspect of our business would likely require significant capital and would take time to achieve. Such activities could also distract our management team from its present business initiatives, which could have a material and adverse effect on our business. There is also the risk that our initiatives in this regard would not yield any viable new inventions or technology, which would lead to a loss of our investments in time and resources in such activities.

In addition, even if we are able to internally develop new inventions, in order for those inventions to be viable and to compete effectively, we would need to develop and maintain, and they would heavily rely on, a proprietary position with respect to such inventions and intellectual property. However, there are significant risks associated with any such intellectual property we may develop principally including the following:

• patent applications we may file may not result in issued patents or may take longer than we expect to result in issued patents;

• we may be subject to interference proceedings;

• we may be subject to opposition proceedings in the U.S. or foreign countries;

• any patents that are issued to us may not provide meaningful protection;

• we may not be able to develop additional proprietary technologies that are patentable;

• other companies may challenge patents issued to us;

• other companies may have independently developed and/or patented (or may in the future independently develop and patent) similar or alternative technologies, or duplicate our technologies;

35

• other companies may design around patents we have developed; and

• enforcement of our patents could be complex, uncertain and very expensive.

We cannot be certain that patents will be issued as a result of any future applications, or that any of our patents, once issued, will provide us with adequate protection from competing products. For example, issued patents may be circumvented or challenged, declared invalid or unenforceable, or narrowed in scope. In addition, since publication of discoveries in scientific or patent literature often lags behind actual discoveries, we cannot be certain that we will be the first to make our additional new inventions or to file patent applications covering those inventions. It is also possible that others may have or may obtain issued patents that could prevent us from commercializing our products or require us to obtain licenses requiring the payment of significant fees or royalties in order to enable us to conduct our business. As to those patents that we may license or otherwise monetize, our rights will depend on maintaining our obligations to the licensor under the applicable license agreement, and we may be unable to do so. Our failure to obtain or maintain intellectual property rights for our inventions would lead to the loss of our investments in such activities, which would have a material and adverse effect on our company.

Moreover, patent application delays could cause delays in recognizing revenue from our internally generated patents and could cause us to miss opportunities to license patents before other competing technologies are developed or introduced into the market.

New legislation, regulations or court rulings related to enforcing patents could harm our business and operating results.

If Congress, the USPTO or courts implement new legislation, regulations or rulings that impact the patent enforcement process or the rights of patent holders, these changes could negatively affect our business model. For example, limitations on the ability to bring patent enforcement claims, limitations on potential liability for patent infringement, lower evidentiary standards for invalidating patents, increases in the cost to resolve patent disputes and other similar developments could negatively affect our ability to assert our patent or other intellectual property rights.

In addition, on September 16, 2011, the Leahy-Smith America Invents Act (or the Leahy-Smith Act) was signed into law. The Leahy-Smith Act includes a number of significant changes to the United States patent law. These changes include provisions that affect the way patent applications will be prosecuted and may also affect patent litigation. As the regulations and procedures to govern administration of the Leahy-Smith Act, were only recently fully effective, it is too early to tell what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of patents issued to us, all of which could have a material adverse effect on our business and financial condition.

Further, and in general, it is impossible to determine the extent of the impact of any new laws, regulations or initiatives that may be proposed, or whether any of the proposals will become enacted as laws. Compliance with any new or existing laws or regulations could be difficult and expensive, affect the manner in which we conduct our business and negatively impact our business, prospects, financial condition and results of operations.

Acquisitions of additional patent assets may be time consuming, complex and costly, which could adversely affect our operating results.

Acquisitions of patent or other intellectual property assets, which are and will be critical to our business plan, are often time consuming, complex and costly to consummate. We may utilize many different transaction structures in our acquisitions and the terms of such acquisition agreements tend to be heavily negotiated. As a result, we expect to incur significant operating expenses and will likely be required to raise capital during the negotiations even if the acquisition is ultimately not consummated. Even if we are able to acquire particular patent assets, there is no guarantee that we will generate sufficient revenue related to those patent assets to offset the acquisition costs. While we will seek to conduct confirmatory due diligence on the patent assets we are considering for acquisition, we may acquire patent assets from a seller who does not have proper title to those assets. In those cases, we may be required to spend significant resources to defend our interest in the patent assets and, if we are not successful, our acquisition may be invalid, in which case we could lose part or all of our investment in the assets.

 We may also identify patent or other intellectual property assets that cost more than we are prepared to spend with our own capital resources. We may incur significant costs to organize and negotiate a structured acquisition that does not ultimately result in an acquisition of any patent assets or, if consummated, proves to be unprofitable for us. These higher costs could adversely affect our operating results, and if we incur losses, the value of our securities will decline.

In addition, we may acquire patents and technologies that are in the early stages of adoption in the commercial, industrial and consumer markets. Demand for some of these technologies will likely be untested and may be subject to fluctuation based upon the rate at which our licensees will adopt our patents and technologies in their products and services. As a result, there can be no assurance as to whether technologies we acquire or develop will have value that we can monetize.

In certain acquisitions of patent assets, we may seek to defer payment or finance a portion of the acquisition price. This approach may put us at a competitive disadvantage and could result in harm to our business.

We have limited capital and may seek to negotiate acquisitions of patent or other intellectual property assets where we can defer payments or finance a portion of the acquisition price. These types of debt financing or deferred payment arrangements may not be as attractive to sellers of patent assets as receiving the full purchase price for those assets in cash at the closing of the acquisition. As a result, we might not compete effectively against other companies in the market for acquiring patent assets, some of whom have greater cash resources than we have.

Any failure to maintain or protect our patent assets or other intellectual property rights could significantly impair our return on investment from such assets and harm our brand, business and operating results.

Our ability to operate our business and compete in the intellectual property market largely depends on the superiority, uniqueness and value of our patent assets and other intellectual property. To protect our proprietary rights, we rely on and will rely on a combination of patent, trademark, copyright and trade secret laws, confidentiality agreements with our employees and third parties, and protective contractual provisions. No assurances can be given that any of the measures we undertake to protect and maintain our assets will have any measure of success.

36

Following the acquisition of patent assets, we will likely be required to spend significant time and resources to maintain the effectiveness of those assets by paying maintenance fees and making filings with the USPTO. We may acquire patent assets, including patent applications, which require us to spend resources to prosecute the applications with the USPTO. Further, there is a material risk that patent related claims (such as, for example, infringement claims (and/or claims for indemnification resulting therefrom), unenforceability claims, or invalidity claims) will be asserted or prosecuted against us, and such assertions or prosecutions could materially and adversely affect our business. Regardless of whether any such claims are valid or can be successfully asserted, defending such claims could cause us to incur significant costs and could divert resources away from our other activities.

Despite our efforts to protect our intellectual property rights, any of the following or similar occurrences may reduce the value of our intellectual property:

• our applications for patents, trademarks and copyrights may not be granted and, if granted, may be challenged or invalidated;

• issued trademarks, copyrights, or patents may not provide us with any competitive advantages versus potentially infringing parties;

• our efforts to protect our intellectual property rights may not be effective in preventing misappropriation of our technology; or

• our efforts may not prevent the development and design by others of products or technologies similar to or competitive with, or superior to those we acquire and/or prosecute.

Moreover, we may not be able to effectively protect our intellectual property rights in certain foreign countries where we may do business in the future or from which competitors may operate. If we fail to maintain, defend or prosecute our patent assets properly, the value of those assets would be reduced or eliminated, and our business would be harmed.

Weak global economic conditions may cause infringing parties to delay entering into licensing agreements, which could prolong our litigation and adversely affect our financial condition and operating results.

Our business plan depends significantly on worldwide economic conditions, and the United States and world economies have recently experienced weak economic conditions. Uncertainty about global economic conditions poses a risk as businesses may postpone spending in response to tighter credit, negative financial news and declines in income or asset values. This response could have a material negative effect on the willingness of parties infringing on our assets to enter into licensing or other revenue generating agreements voluntarily. Entering into such agreements is critical to our business plan, and our failure to do so could cause material harm to our business.

The exercise of a substantial number of warrants or options by our security holders may have an adverse effect on the market price of our common stock.

Should our warrants outstanding as of May 8, 2013, be exercised, there would be an additional 18,764,114 shares of common stock eligible for trading in the public market. In addition, we currently have incentive equity instruments outstanding to purchase 15,282,983 shares of our common stock granted to our management, employees, directors and consultants. Certain options granted to officers, directors and certain key employees are subject to acceleration of vesting of up to 100% (according to the agreement signed with each grantee), upon a subsequent change of control. Certain options that are outstanding have exercise prices that are below, and in some cases significantly below, recent market prices. Such securities, if exercised, will increase the number of issued and outstanding shares of common stock. Therefore, the sale, or even the possibility of sale, of the shares of common stock underlying the warrants and options could have an adverse effect on the market price for our securities or on our ability to obtain future financing. The average weighted exercise price of all currently outstanding warrants and options, as of May 8, 2013, is $3.19 per share.

Future sales of our shares of common stock by our stockholders could cause the market price of our common stock to drop significantly, even if our business is otherwise performing well.

As of May 8, 2013, we had 82,749,093 shares of common stock issued and outstanding, excluding shares of common stock issuable upon exercise of warrants, options or restricted stock units (“RSUs”). As shares saleable under Rule 144 are sold or as restrictions on resale lapse, the market price of our common stock could drop significantly, if the holders of restricted shares sell them, or are perceived by the market as intending to sell them. This decline in our stock price could occur even if our business is otherwise performing well.

If we are unable to adequately protect our intellectual property, we may not be able to compete effectively. In addition, the possibility of extensive delays in the patent issuance process could effectively reduce the term during which a marketed product is protected by patents.

We may need to obtain licenses to patents or other proprietary rights from third parties. We may not be able to obtain the licenses required under any patents or proprietary rights or they may not be available on acceptable terms. If we do not obtain required licenses, we may encounter delays in product development or find that the development, manufacture or sale of products requiring licenses could be foreclosed. We may, from time to time, support and collaborate in research conducted by universities and governmental research organizations. We may not be able to acquire exclusive rights to the inventions or technical information derived from these collaborations, and disputes may arise over rights in derivative or related research programs conducted by us or in such collaborators.

37

Our ability to compete depends in part upon the strength of our proprietary rights in our technologies, brands and content. We rely on a combination of U.S. and foreign patents, copyrights, trademark, trade secret laws and license agreements to establish and protect our intellectual property and proprietary rights. The efforts we have taken to protect our intellectual property and proprietary rights may not be sufficient or effective at stopping unauthorized use of our intellectual property and proprietary rights. In addition, effective trademark, patent, copyright and trade secret protection may not be available or cost-effective in every country in which our services are made available through the Internet. There may be instances where we are not able to fully protect or utilize our intellectual property in a manner that maximizes competitive advantage. If we are unable to protect our intellectual property and proprietary rights from unauthorized use, the value of our products may be reduced, which could negatively impact our business. Our inability to obtain appropriate protection for our intellectual property may also allow competitors to enter our markets and produce or sell the same or similar products. In addition, protecting our intellectual property and other proprietary rights is expensive and diverts critical managerial resources. If any of the foregoing were to occur, or if we are otherwise unable to protect our intellectual property and proprietary rights, our business and financial results could be adversely affected.

If we are forced to resort to legal proceedings to enforce our intellectual property rights, the proceedings could be burdensome and expensive. In addition, our proprietary rights could be at risk if we are unsuccessful in, or cannot afford to pursue, those proceedings. We also rely on trade secrets and contract law to protect some of our proprietary technology. We entered into confidentiality and invention agreements with our employees and consultants. Nevertheless, these agreements may not be honored and they may not effectively protect our right to our un-patented trade secrets and know-how. Moreover, others may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets and know-how.

If we or our users infringe on the intellectual property rights of third parties, we may have to defend against litigation and pay damages and our business and prospects may be adversely affected.

If a third party were to assert that our products infringe on our patent, copyright, trademark, right of publicity, right of privacy, trade secret or other intellectual property rights, we could incur substantial litigation costs and be forced to pay substantial damages. Third-party infringement claims, regardless of their outcome, would not only consume significant financial resources, but would also divert our management time and attention. Such claims or the lack of available access to certain sites or content could also cause our customers or potential customers to purchase competitors’ products if such competitors have access to the sites or contents that we are lacking or defer or limit their purchase or use of our products or services until resolution of the claim. In connection with any such claim or litigation, our mobile carriers and other partners may decide to re-assess their relationships with us, especially if they perceive that they may have potential liability or if such claimed infringement is a possible breach of our agreement with such mobile carrier. If any of our products are found to violate third-party intellectual property rights, we may have to re-engineer one or more of our products, or we may have to obtain licenses from third parties to continue offering our products without substantial re-engineering. Our efforts to re-engineer or obtain licenses could require significant expenditures of time and money and may not be successful. Accordingly, any claims or litigation regarding our infringement of intellectual property of a third party by us or our users could have a material adverse effect on our business and prospects.

We may not be able to continue to maintain our application on all of the operating systems that we currently support.

Some of our applications are compatible with various mobile operating systems including Android, Blackberry, Sony Ericsson, Symbian, Apple’s iOS, Java, and Windows Mobile operating systems. While Windows Mobile, Blackberry and Android do not support video ringtones natively, our development team has enabled our application to work on many devices which utilize these operating systems. The user base for the video ringtone service is spread out amongst a number of smartphone and feature phone operating systems, with applications on each aforementioned operating system representing less than 5% of the total subscribers to our video ringtone platform. Our Facetones® platform, which represented less than 5% of our revenue for the three month period ended March 31, 2013, is heavily reliant upon our Android devices users. Currently, over 96% of our Facetones® users utilize the Android operating system. In addition, our commercial agreement with ZTE is solely reliant on our ability to maintain our support for the Android operating system. Since these operating systems do not support our applications natively, any significant changes to these operating systems by their respective developers may prevent our application from working properly or at all on these systems. If we are unable to maintain our application on these operating systems or on any other operating systems, users of these operating systems will not be able to use our application, which could adversely affect our business and results of operations.

38

Our business depends upon our ability to keep pace with the latest technological changes and our failure to do so could make us less competitive in our industry.

The market for our products and services is characterized by rapid change and technological change, frequent new product innovations, changes in customer requirements and expectations and evolving industry standards. Products using new technologies or emerging industry standards could make our products and services less attractive. Furthermore, our competitors may have access to technology not available to us, which may enable them to produce products of greater interest to consumers or at a more competitive cost. Failure to respond in a timely and cost-effective way to these technological developments may result in serious harm to our business and operating results. As a result, our success will depend, in part, on our ability to develop and market product and service offerings that respond in a timely manner to the technological advances available to our customers, evolving industry standards and changing preferences.

Regulation concerning consumer privacy may adversely affect our business.

Certain technologies that we currently support, or may in the future support, are capable of collecting personally-identifiable information. We anticipate that as mobile telephone software continues to develop, it will be possible to collect or monitor substantially more of this type of information. A growing body of laws designed to protect the privacy of personally-identifiable information, as well as to protect against its misuse, and the judicial interpretations of such laws, may adversely affect the growth of our business. In the United States, these laws could include the Federal Trade Commission Act, the Electronic Communications Privacy Act, the Fair Credit Reporting Act and the Gramm-Leach Bliley Act, as well as various state laws and related regulations. In addition, certain governmental agencies, like the Federal Trade Commission, have the authority to protect against the misuse of consumer information by targeting companies that collect, disseminate or maintain personal information in an unfair or deceptive manner. In particular, such laws could limit our ability to collect information related to users or our services, to store or process that information in what would otherwise be the most efficient manner, or to commercialize new products based on new technologies. The evolving nature of all of these laws and regulations, as well as the evolving nature of various governmental bodies’ enforcement efforts, and the possibility of new laws in this area, may adversely affect our ability to collect and disseminate or share certain information about consumers and may negatively affect our ability to make use of that information. If we fail to successfully comply with applicable regulations in this area, our business and prospects could be harmed.

Our ability to raise capital through equity or equity-linked transactions may be limited.

In order for us to raise capital privately through equity or equity-linked transactions, stockholder approval is required to enable us to issue more than 19.99% of our outstanding shares of common stock pursuant to the rules and regulations of the NASDAQ Capital Market. Should stockholders not approve such issuances, one means to raise capital would be through debt, which could have a material adverse effect on our balance sheet and overall financial condition.

We may not be able to raise additional capital. Moreover, additional financing may have an adverse effect on the value of the equity instruments held by our stockholders.

We may choose to raise additional funds in connection with any potential acquisition of patent portfolios or other intellectual property assets or operating businesses. In addition, we may also need additional funds to respond to business opportunities and challenges, including our ongoing operating expenses, protection of our assets, development of new lines of business and enhancement of our operating infrastructure. While we will need to seek additional funding, we may not be able to obtain financing on acceptable terms, or at all. In addition, the terms of our financings may be dilutive to, or otherwise adversely affect, holders of our common stock. We may also seek additional funds through arrangements with collaborators or other third parties. We may not be able to negotiate arrangements on acceptable terms, if at all. If we are unable to obtain additional funding on a timely basis, we may be required to curtail or terminate some or all of our business plans. Any such financing that we undertake will likely be dilutive to our current stockholders.

39

Because our current revenues are, and are expected to be, generated in U.S Dollars, British Pounds and Euros, while a portion of our expenses is, and is expected to be, incurred in British Pounds, Euros and in New Israeli Shekels, our results may be significantly affected by currency exchange rate fluctuations.

Our revenues are, and are expected to be, generated in U.S Dollars, Euros and in the British Pound, while significant salary related expenses are paid in New Israeli Shekels and expenses related to maintaining, prosecuting and enforcing the patents acquired from Nokia are expected to be paid in British Pounds and in Euros. As a result, we are exposed to the adverse effect of increased dollar-measured cost of our operations, as value of these currencies may materially fluctuate against the U.S Dollar, as it is affected by, among other things, changes in political and economic conditions. Fluctuations in the abovementioned exchange rates, or even the appearance of instability in any such exchange rate, could adversely affect our ability to operate our business.

The termination or reduction of tax and other incentives that the Israeli government provides to domestic companies, such as our wholly-owned Israeli subsidiary, may increase our operating costs in Israel.

The Israeli government currently provides tax and capital investment incentives to domestic companies, as well as grant and loan programs relating to research and development and marketing and export activities. Our wholly-owned Israeli subsidiary currently takes advantage of some of these programs. We cannot provide any assurance that such benefits and programs will continue to be available in the future to our Israeli subsidiary. In addition, it is possible that our subsidiary will fail to meet the criteria required for eligibility of future benefits. If such benefits and programs were terminated or further reduced, it could have an adverse effect on our business, operating results and financial condition.

Commitments and Contingencies

Note 8—Commitments and Contingencies

The Company retains the services of law firms that specialize in intellectual property licensing, enforcement and patent law. These law firms are retained on an hourly fee, monthly fee, project fee, contingent fee, or blended fee basis. In a contingency fee arrangement, law firms are paid a scaled percentage of any negotiated fees, settlements or judgments awarded, based on how and when the fees, settlements or judgments are obtained.

On November 6, 2012, the Company received a verdict in its case against AOL, Inc., Google, Inc., IAC Search & Media, Inc., Gannett Company, Inc. and Target Corporation (collectively, "Defendants") with respect to the Defendants' infringement of the asserted claims of U.S. Patent Nos. 6,314,420 and 6,775,664 (collectively, the "IPE Patents"). After finding that the asserted claims of the IPE Patents were not invalid, and infringed by the Defendants, the jury found that reasonable royalty damages should be based on a "running royalty", and that the running royalty rate should be 3.5%. The jury also found that the following sums of money, if paid now in cash, would reasonably compensate I/P Engine for the Defendants’ past infringement as follows: Google: $15,800, AOL: $7,943, IAC: $6,650, Gannett: $4, Target: $99. Motions by I/P Engine for awards of pre-judgment interest, post-judgment interest, supplemental damages and post-judgment royalties, are pending in U.S. District Court. I/P Engine and Defendants have filed notices of appeal with the Court of Appeals for the Federal Circuit. In response to a request by Google, Inc., the IPE Patents are being reexamined by the U.S. Patent and Trademark Office (see also Note 9 (b)). On January 31, 2013, I/P Engine filed an action asserting infringement of the IPE Patents in the United States District Court, Southern District of New York, against Microsoft Corporation. According to certain scaled fee agreements, I/P Engine will pay between 15% and 20% of any recovery to professional service providers. As of March 31, 2013, the Company did not record any revenue, nor a liability for any potential, contingent, legal fees, related to these litigations, as timing of collection, if any, or the amounts due to it, cannot be determined.

From October 2012 through March 31, 2013, the Company’s subsidiaries filed patent infringement lawsuits against the subsidiaries of ZTE Corporation in the United Kingdom, France and Germany. Should the Company be deemed the losing party in any of its applications to the court in the UK, it may be held responsible for a substantial percentage of the defendant’s legal fees for the relevant application or for the litigation. As a result, the Company placed a guarantee to ensure the payment of a potential liability, which the defendants estimated to be approximately $2,900. However, should the Company be successful on any court applications or the entire litigation, ZTE would be responsible for a substantial percentage of its legal fees. In addition, the Company will grant additional guarantees, as necessary, in connection with its commenced proceedings against ZTE in Europe.

In July 2012, the Company signed a rental agreement for its new headquarters in New York. According to the new agreement, the Company shall pay an annual fee of approximately $137 (subject to certain adjustments). The Company’s subsidiary in Israel leases an office space for a period of up to four years (including options to extend the terms of the lease). According to the agreement, the subsidiary in Israel shall pay an annual fee of approximately $72 (in NIS, subject to certain adjustments). Rent expense for operating leases and automobiles for the three month periods ended March 31, 2013 and 2012, and the cumulative period from Inception until March 31, 2013, was $53, $8 and $227, respectively.

Future minimum lease payments under non-cancelable operating leases for office space and cars, as of March 31, 2013, are as follows:

Risks and Uncertainties

3 Months Ended

Mar. 31, 2013

Risks and Uncertainties [Abstract]

Risks and Uncertainties

Note 9—Risks and Uncertainties

(a)	New legislation, regulations or rulings that impact the patent enforcement process or the rights of patent holders, could negatively affect the Company’s current business model. For example, limitations on the ability to bring patent enforcement claims, limitations on potential liability for patent infringement, lower evidentiary standards for invalidating patents, increases in the cost to resolve patent disputes and other similar developments could negatively affect the Company’s ability to assert its patent or other intellectual property rights.
(b)	As part of the Company’s ongoing legal proceedings, the validity and/or enforceability of the patents is often challenged in a court or administrative proceeding. Several of the Company’s patents are being challenged in several jurisdictions. In particular, on March 15, 2012, Google submitted a request to the USPTO for ex parte reexamination of U.S. Patent No. 6,314,420. On July 18, 2012, the USPTO issued a determination ordering a reexamination. On September 25, 2012, the USPTO issued a first, non-final office action where it adopted the rejections proposed by Google. The Company's response was filed on November 26, 2012. A final, appealable office action maintaining the rejections was mailed on May 3, 2013. The Company has until July 3, 2013 to file a response or a notice of appeal to the Patent Trial and Appeal Board. On November 28, 2012, Google submitted a request to the USPTO for ex parte reexamination of U.S. Patent No. 6,775,664. On January 17, 2013, the USPTO issued a determination ordering a reexamination, but found that three of the prior art references identified by Google were not considered prior art to the 6,775,664 patent. Google filed a second reexamination request of that patent on February 8, 2013. On March 7, 2013, the USPTO issued a determination ordering a reexamination based on the three additional references. The Company believes its patents are both valid and enforceable.
(c)	Financial instruments which potentially subject the Company to significant concentrations of credit risk consist principally of cash, cash equivalents, short-term investments and accounts receivable. The Company maintains its cash, cash equivalents and short-term investments with various major financial institutions. These major financial institutions are located in the United States, Germany and Israel, and the Company’s policy is designed to limit exposure to any one institution.
(d)	A portion of the Company’s expenses are denominated in NIS, British Pound and Euro. If the value of the U.S. dollar weakens against the value of these currencies, there will be a negative impact on the Company’s operating costs. In addition, the Company is subject to the risk of exchange rate fluctuations to the extent it holds monetary assets and liabilities in these currencies.

In June 2011, the Company’s subsidiary acquired patents from Lycos, Inc. The gross carrying amount of those patents is comprised of the original purchase price of $3,200 and $196 of associated patent acquisition costs.

In August 2012, the Company purchased from Nokia Corporation a portfolio consisting of various patents and patent applications. The portfolio encompasses a broad range of technologies relating to telecom infrastructure, including communication management, data and signal transmission, mobility management, radio resources management and services. The total consideration paid for the portfolio was $22,000. In addition, the Company capitalized certain costs related to the acquisition of patents in the total amount of $548. Under the terms of the purchase agreement, to the extent that the gross revenue generated by such portfolio exceeds $22,000, the Company is obligated to pay a royalty of 35% of such excess. The Company has not recorded any amounts in respect of this contingent consideration, as both the amounts of future potential revenue, if any, and the timing of such revenue cannot be reliably established.

In October 2012, the Company’s subsidiary entered into a patent purchase agreement. As partial consideration, the Company issued 160,600 shares of common stock to the seller with the fair value of $750. In addition, under the terms of the purchase agreement, 20% of the gross revenue collected will be payable to the seller as a royalty. The Company has not recorded any amounts in respect of this contingent consideration, as both the amounts of future potential revenue, if any, and the timing of such revenue cannot be reliably established.

During the three month periods ended March 31, 2013 and 2012, the Company recorded amortization expense of $1,255 and $155, respectively. During the period from Inception through March 31, 2013, total amortization expense of $4,038 was recorded. Estimated amortization expense for each of the five succeeding years, based upon intangible assets owned at March 31, 2013 is as follows:

Accounting Policies [Abstract]

Significant Accounting and Reporting Policies

Note 2—Significant Accounting and Reporting Policies

(a) Basis of presentation

The accompanying consolidated financial statements include the accounts of the Legal Parent, I/P and their wholly-owned subsidiaries, and are presented in accordance with instructions to Form 10-Q and, therefore, do not include all disclosures necessary for a complete presentation of financial position, results of operations, and cash flows in conformity with U.S. generally accepted accounting principles. These financial statements should be read in conjunction with the consolidated financial statements and related notes for the year ended December 31, 2012. The results of operations for the three month period ended March 31, 2013 are not necessarily indicative of the results that may be expected for the entire fiscal year or for any other interim period. All significant intercompany balances and transactions have been eliminated in consolidation. These financial statements include the results of operations of I/P and its subsidiaries for all periods presented, with the results of operations of the Legal Parent and its subsidiaries for the period from July 19, 2012 (the effective date of the Merger). Moreover, equity amounts, as well as net loss per common share, presented for comparative periods differ from those previously presented by I/P, due to application of accounting requirements applicable to a reverse acquisition.

(b) Development stage enterprise

The Company’s principal activities to date have been focused on enforcement and development of its intellectual property, as well as on the research and development of its products. To date, the Company has not generated any significant revenues from its planned principal operations. Accordingly, the Company’s financial statements are presented as those of a development stage enterprise.

(c) Translation into U.S. dollars

The currency of the primary economic environment in which the operations of the Company are conducted is the U.S. dollar ("U.S. $" or “$”). Therefore, the U.S. dollar has been determined to be the Company's functional currency. Post-Merger, the Company conducted significant transactions in foreign currencies (primarily the New Israeli Shekels ("NIS") and Euro). These are recorded at the exchange rate as of the transaction date. All exchange gains and losses from remeasurement of monetary balance sheet items denominated in non-dollar currencies are reflected as finance expense in the statement of operations, as they arise.

	NIS		Euro
At March 31, 2013		3.648		0.782
At December 31, 2012		3.733		0.759
Average exchange rate for the period from July 19, 2012 through March 31, 2013		3.846		0.775
Average exchange rate for the period from January 1, 2013 through March 31, 2013		3.708		0.757

(d) Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results may differ from such estimates. Significant items subject to such estimates and assumptions include valuation of assets assumed and liabilities incurred as part of the Merger, useful lives of the Company’s tangible and intangible assets, valuation of its short-term investments and the October 2012 Warrants (as defined in Note 7) and derivative warrants, valuation of its share-based compensation, deferred tax assets and liabilities, income tax uncertainties and other contingencies.

(e) Cash and cash equivalents

The Company invests its surplus cash in commercial paper, money market deposits and money market funds with financial institutions. The Company has established guidelines relating to diversification and maturities of its investments, in order to minimize credit risk and maintain high liquidity of funds. For the purpose of these financial statements, all highly liquid investments with original maturities of three months or less are considered cash equivalents. Cash and cash equivalents include $740 and $0 invested in commercial papers with an initial term (upon purchase by the Company) of less than three months at March 31, 2013 and December 31, 2012, respectively.

(f) Short-term investments

Currently, short-term investment securities as of March 31, 2013 and December 31, 2012, in the total amount of $3,120 and $0, respectively, consist of investment in commercial paper. The Company classified its investments as held-to-maturity. Held-to-maturity debt securities are those debt securities in which the Company has the ability and intent to hold the security until maturity. Held-to-maturity debt securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts. Premiums and discounts on debt securities are amortized or accreted over the life of the related held-to-maturity security as an adjustment to yield using the effective-interest method. Such amortization and accretion is included in the “non-operating income” line item in the Consolidated Statements of Operations. Dividend and interest income are recognized when earned.

(g) Net loss per share data

Basic net loss per share is computed by dividing the net loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing the net loss for the period by the weighted-average number of shares of common stock plus dilutive potential common stock considered outstanding during the period. Such dilutive shares consist of incremental shares that would be issued upon exercise of the Company’s derivative warrants (see also Note 7). The table below presents the computation of basic and diluted net losses per common share:

Series Convertible Preferred Stock [Abstract]

Series A Convertible Preferred Stock

Note 6—Series A Convertible Preferred Stock

Prior to the Merger, I/P was authorized to issue up to 10,000,000* shares of preferred stock, par value $0.0001, of which 6,968* shares of preferred stock were designated as Series A Convertible Preferred Stock with such rights and preferences designated in the relevant Certificate of Designations (the “Series A Preferred Stock”). In June 2011, I/P issued 6,968* shares of Series A Preferred Stock to Hudson Bay for $1,800. The Series A Preferred Stock had a liquidation preference of $1,250 per share and was otherwise convertible, at the option of the holder, into 6,968,000* shares of I/P’s common stock at a conversion price of $1 per common share received, subject to adjustment for anti-dilution and other corporate events. In 2012, prior to the Merger, 295 shares of Series A Convertible Preferred Stock were converted into 295,000* shares of common stock of I/P.

Prior to the Merger, the Series A Convertible Preferred Stock was classified as mezzanine equity, because of certain cash redemption triggering events which were outside the control of the Company. Upon the Merger, the remaining 6,673* Series A Preferred stock shares were exchanged for 6,673 shares of equity-classified new Series A Convertible Preferred Stock, $0.01 par value (“New Series A Convertible Preferred Stock”), issued by Legal Parent to former stockholders of I/P, as part of the Merger. The shares of New Series A Convertible Preferred Stock were convertible into 20,136,445 shares of the Legal Parent’s shares of common stock and were classified as equity, as a cash-based redemption event is only triggered by events which are fully in the control of the Company. In August 2012, following the consummation of the Merger, all outstanding shares of New Series A Convertible Preferred Stock were converted.

* Share amounts were not retrospectively restated to reflect Vringo’s equity instruments after the Merger.

Fair Value Measurements [Abstract]

Fair Value Measurements

Note 4—Fair Value Measurements

The Company measures fair value in accordance with ASC 820-10, “Fair Value Measurements and Disclosures” (formerly SFAS 157, “Fair Value Measurements”). ASC 820-10 clarifies that fair value is an exit price, representing the amount that would be received by selling an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, ASC 820-10 establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

Level 2 Inputs: Inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant inputs are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The Company measures its derivative liabilities at fair value. The Special Bridge Warrants, Conversion Warrants, Preferential Reload Warrants and Series 1 Warrants (as they are defined in Note 7) are classified within Level 3 because they are valued using the Black-Scholes-Merton and the Monte-Carlo models (as all of these warrants include down-round protection clauses), which utilize significant inputs that are unobservable in the market.

The following table presents the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2013 and December 31, 2012, aggregated by the level in the fair-value hierarchy within which those measurements fall:

			Fair value measurement at reporting date using
			Quoted prices in

In addition to the above, the Company’s financial instruments at March 31, 2013 and December 31, 2012 consisted of cash, cash equivalents, short-term investments, accounts receivable, accounts payable and long term deposits. The carrying amounts of all the aforementioned financial instruments approximate fair value. The following table summarizes the changes in the Company’s liabilities measured at fair value using significant unobservable inputs (Level 3) during the period from Inception through March 31, 2013. No assets, nor liabilities, were valued using Level 3 inputs for the period ended March 31, 2012:

Fair value measurement of the derivative liability on account of Special Bridge Warrants, Conversion Warrants, Preferential Reload Warrants and Series 1 Warrants (as defined in Note 7) fall within Level 3 of the fair value hierarchy. The fair value measurements are evaluated by management to ensure that changes are consistent with expectations of management based upon the sensitivity and nature of the inputs.

Description	Valuation technique	Unobservable inputs	Range
Special Bridge Warrants, Conversion Warrants, Preferential Reload Warrants and the Series 1 Warrants	Black-Scholes-Merton and the Monte-Carlo models	Volatility		56.48% – 58.10%
		Risk free interest rate		0.25% – 0.60%
		Expected term, in years		1.75 – 4.30
		Dividend yield		0%
		Probability and timing of down-round triggering event		15% occurrence in December 2013

Sensitivity of Level 3 measurements to changes in significant unobservable inputs

The inputs to estimate the fair value of the Company’s derivative warrant liability are the current market price of the Company’s common stock, the exercise price of the warrant, its remaining expected term, the volatility of the Company’s common stock market price, the Company’s estimations regarding the probability and timing of a down-round protection triggering event and the risk-free interest rate. Significant changes in any of those inputs in isolation can result in a significant change in the fair value measurement. Generally, a positive change in the market price of the Company’s common stock, and an increase in the volatility of the Company’s shares of common stock, or an increase in the remaining term of the warrant, or an increase of a probability of a down-round triggering event would each result in a directionally similar change in the estimated fair value of the Company’s warrants and thus an increase in the associated liability and vice-versa. An increase in the risk-free interest rate or a decrease in the positive differential between the warrant’s exercise price and the market price of the Company’s shares of common stock would result in a decrease in the estimated fair value measurement of the warrants and thus a decrease in the associated liability. The Company has not, nor plans to, declare dividends on its common stock, and thus, there is no change in the estimated fair value of the warrants due to the dividend assumption.

Business Combination

Note 5 – Business Combination

On July 19, 2012, I/P consummated the Merger with the Legal Parent, as also described in Note 1. The consideration consisted of various equity instruments, including: shares of common stock, preferred stock, options and warrants. The purpose of the Merger was to increase the combined company's intellectual property portfolio and array of products, to gain access to capital markets, and for other reasons. Upon completion of the Merger, (i) all then outstanding 6,169,661 common stock shares of I/P, par value $0.0001 per share, were exchanged for 18,617,569, shares of the Company’s common stock, par value $0.01 per share, and (ii) all then outstanding shares of Series A Convertible Preferred Stock of I/P, par value $0.0001 per share, were exchanged for 6,673 shares of the Legal Parent’s Series A Convertible Preferred Stock, par value $0.01 per share, which shares were convertible into 20,136,445 shares of common stock of the Legal Parent. In addition, the Legal Parent issued to the holders of I/P capital stock an aggregate of 15,959,838 warrants to purchase an aggregate of 15,959,838 shares of the Company’s common stock with an exercise price of $1.76 per share. The Company recorded such warrants as a derivative long-term liability in the total amount of $21,954 (see also Note 4). In addition, all outstanding and unexercised options to purchase I/P common stock, whether vested or unvested, were converted into 41,178 options to purchase the Company’s common stock. Immediately following the completion of the Merger, the former stockholders of I/P owned approximately 55.04% of the outstanding common stock of the combined company (or 67.61% of the outstanding shares of the Company’s common stock, calculated on a fully diluted basis), and the Legal Parent’s stockholders prior to the Merger owned approximately 44.96% of the outstanding common stock of the combined company (or 32.39% of the outstanding shares of its common stock calculated on a fully diluted basis). For accounting purposes, I/P was identified as the accounting “acquirer”, as it is defined in FASB Topic ASC 805. The total purchase price of $75,654 was allocated to the assets acquired and liabilities assumed of the Legal Parent. Registration and issuance cost, in the total amount of $463, was recorded against the additional paid-in capital.

	Provisional allocation of purchase price
Current assets, net of current liabilities		2,586
Long-term deposit		8
Property and equipment		124
Technology		10,133
Goodwill		65,965
Total assets acquired, net		78,816
Fair value of outstanding warrants granted by Legal Parent prior to the Merger, classified as a long-term derivative liability		(3,162	)
Total liabilities assumed, net		(3,162	)
		75,654
Measurement of consideration:
Fair value of vested stock options granted to employees, management and consultants, classified as equity		7,364
Fair value of outstanding warrants granted by the Legal Parent prior to the Merger, classified as equity		10,079
Fair value of Vringo shares of common stock and vested $0.01 options granted to employees, management and consultants		58,211
Total estimated purchase price		75,654

The fair values of the identified intangible assets were estimated using an income approach. Under the income approach, an intangible asset’s fair value is equal to the present value of future economic benefits to be derived from ownership of the asset. Indications of value are developed by discounting future net cash flows to their present value at market-based rates of return. The goodwill recognized as a result of the acquisition is primarily attributable to the value of the workforce and other intangible asset arising as a result of name, operational synergies, products, and similar factors which could not be separately identified. The useful life of the intangible assets for amortization purposes was determined considering the period of expected cash flows used to measure the fair value of the intangible assets adjusted as appropriate for the entity-specific factors including legal, regulatory, contractual, competitive economic or other factors that may limit the useful life of intangible assets. As of March 31, 2013, according to ASC 805, the purchase price allocation is still provisional. The Company expects the existing value of its goodwill to change upon completion of a study regarding its total net tax loss carryforwards utilizable for tax purposes, performed by a third party expert. Goodwill recognized is not deductible for income tax purposes. Had the acquisition taken place on June 8, 2011 (Inception), the revenue in the consolidated statement of operations and the consolidated net loss would have been as follows:

	Three month period ended March 31, 2012					Cumulative from Inception to March 31, 2013
	Revenue		Net Loss			Revenue		Net Loss
Total amount		106		(7,762	)		1,074		(52,580	)

The pro forma adjustment consists of amortization of acquired technology. The amortization, net, for the three month period ended March 31, 2012 would have been $247. The amortization, net, for the period from Inception through March 31, 2013 would have been $1,789. The above pro forma disclosure excludes the possible impact of valuation of equity and derivative instruments valued in connection with the Merger.

(b) Equity Incentive Plan

In August 2011, I/P adopted its 2011 Equity and Performance Incentive Plan (the “I/P 2011 Plan”). The I/P 2011 Plan provided for the issuance of stock options and restricted stock to the Company’s directors, employees and consultants. Terminated, expired or forfeited grants may be reissued under the I/P 2011 Plan. The number of shares available under I/P 2011 Plan was subject to adjustments for certain changes. Following the Merger with the Legal Parent, the I/P 2011 Plan was assumed by the Company’s 2012 Employee, Director and Consultant Equity Incentive Plan (“2012 Plan”).

On July 19, 2012, following the Merger with the Legal Parent, the Company’s stockholders approved the 2012 Plan, replacing the existing 2006 Stock Option Plan of the Legal Parent, and the remaining 9,100,000 authorized shares thereunder were cancelled. The 2012 Plan was approved in order to ensure full compliance with legal and tax requirements under U.S. law. The number of shares subject to the 2012 Plan is the sum of: (i) 15,600,000 shares of common stock, which constitutes 6,500,000 new shares and 9,100,000 previously authorized but unissued shares under the 2006 Stock Option Plan and (ii) any shares of common stock that are represented by awards granted under the Legal Parent’s 2006 Stock Option Plan that are forfeited, expired or are cancelled without delivery of shares of common stock or which result in the forfeiture of shares of common stock back to the Company, or the equivalent of such number of shares after the administrator, in its sole discretion, has interpreted the effect of any stock split, stock dividend, combination, recapitalization or similar transaction in accordance with the 2012 Plan; provided, however, that no more than 3,200,000 shares shall be added to the 2012 Plan. As of March 31, 2013, 3,722,750 shares were available for future grants under the 2012 Plan.

(c) Stock options and RSUs

The following table illustrates the common stock options granted for the three month period ended March 31, 2013:

Title	Grant date	No. of options		Exercise price		Share price at grant date		Vesting terms	Assumptions used in Black-Scholes option pricing model

For the three month periods ended March 31, 2013 and 2012, the Company recorded total stock compensation expense of $3,094 and $84, respectively. Cumulatively from Inception through March 31, 2013, the Company has recorded stock compensation expense of $11,655.

The Company cumulatively did not create tax benefits related to its stock-based compensation due to a full valuation allowance in the U.S.

(d) Warrants

The following table summarizes information about warrant activity for the three month period ended March 31, 2013: 

	No. of warrants			Weighted average exercise price		Exercise price range
Outstanding at January 1, 2013		18,863,261		$	3.11		$0.94 – $5.06
Granted		—			—		—
Exercised		(94,147	)	$	1.76		$1.76
Outstanding at March 31, 2013		18,769,114		$	3.12		$0.94 – $5.06

The Company’s outstanding warrants consisted of the following:

(a) Series 1 and Series 2 Warrants

As part of the Merger, on July 19, 2012, the Legal Parent issued to I/P’s stockholders 8,299,116 warrants at an exercise price of $1.76 per share and contractual term of 5 years (“Series 1 Warrant”). These warrants bear down-round protection clauses and as a result, they were classified as a long-term derivative liability and recorded at fair value. In addition, I/P’s stockholders received another 7,660,722 warrants at an exercise price of $1.76 per share and contractual term of 5 years (“Series 2 Warrant”). As the Series 2 Warrants do not have down-round protection clauses, they were classified as equity. During the three month period ended March 31, 2013, 48,957 Series 1 Warrants and 45,190 Series 2 Warrants were exercised. From Inception and through March 31, 2013, 4,704,056 Series 1 Warrants and 1,326,060 Series 2 Warrants were exercised.

(b) Conversion Warrants, Special Bridge Warrants and Reload Warrants

On July 19, 2012, the date of the Merger, Legal Parent’s outstanding warrants included: (i) 148,390 derivative warrants, at an exercise price of $0.94 per share, with a remaining contractual term of 2.44 years (the “Special Bridge Warrants”); (ii) 101,445 derivative warrants, at an exercise price of $0.94 per share, with a remaining contractual term of 2.44 years (the “Conversion Warrants”); (iii) 887,330 derivative warrants, at an exercise price of $1.76 per share, with a remaining contractual term of 4.55 years (the “Preferential Reload Warrants”); and (iv) 814,408 warrants, classified as equity, at an exercise price of $1.76 per share, with a remaining contractual term of 4.55 years (the “non-Preferential Reload Warrants”). During the three month period ended March 31, 2013, none of these warrants were exercised. From Inception and through March 31, 2013, 169,520 non-Preferential Reload Warrants and 726,721 Preferential Reload Warrants were exercised.

(c) Initial Public Offering Warrants

Upon completion of its initial public offering, the Legal Parent issued 4,784,000 warrants at an exercise price of $5.06 per share. These warrants are publicly traded and are exercisable until June 21, 2015, at an exercise price of $5.06 per share. As of March 31, 2013, all of these warrants were outstanding and classified as equity.

(d) October 2012 Warrants

On October 12, 2012, the Company entered into an agreement with certain of its warrant holders, pursuant to which, on October 23 and 24, 2012, the holders exercised in cash 3,721,062 of their outstanding warrants, with an exercise price of $1.76 per share. In exchange, the Company granted such warrant holders unregistered warrants of the Company to purchase an aggregate of 3,000,000 shares of the Company’s common stock, par value $0.01 per share, at an exercise price of $5.06 per share (the “October 2012 Warrants”). The contractual life of these warrants is 2.66 years and because such warrants do not bear any down-round protection clauses they were classified as equity instruments. October 2012 Warrants were valued using the following assumptions: volatility: 68.1%, share price: $3.50-$3.77, risk free interest rate: 0.724% and dividend yield: 0%. The fair value of warrants issued in exchange for the exercise of the Company’s derivative warrants was accounted for as an inducement, therefore an amount of $2,883, was recorded as a non-operating expense. As of March 31, 2013, all October 2012 warrants were outstanding.

Note 1—General

Vringo, Inc., together with its consolidated subsidiaries (the “Company” or “Vringo”), is engaged in the innovation, licensing and protection of intellectual property worldwide. Vringo's intellectual property portfolio consists of over 500 patents and patent applications covering telecom infrastructure, internet search and mobile technologies. The Company’s patents and patent applications have been developed internally and acquired from third parties. Vringo operates a global platform for the distribution of mobile social applications and services it develops.

On July 19, 2012, Vringo, Inc., a Delaware corporation (“Vringo” or “Legal Parent”), closed a merger transaction (the “Merger”) with Innovate/Protect, Inc., a privately held Delaware corporation (“I/P”), pursuant to an Agreement and Plan of Merger, dated as of March 13, 2012 (the “Merger Agreement”), by and among Vringo, I/P and VIP Merger Sub, Inc., a wholly-owned subsidiary of Vringo (“Merger Sub”). Pursuant to the Merger Agreement, I/P became a wholly-owned subsidiary of Vringo through a merger of I/P with and into Merger Sub, and the former stockholders of I/P received shares of Vringo that constituted a majority of the outstanding shares of Vringo.

Because former I/P stockholders owned, immediately following the Merger, approximately 67.61% of the combined company on a fully diluted basis, and as a result of certain other factors, I/P was deemed to be the acquiring company for accounting purposes and the transaction was accounted for as a reverse acquisition in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). Accordingly, the Company’s financial statements for periods prior to the Merger reflect the historical results of I/P and not Vringo’s historical results prior to the Merger, and the Company’s financial statements for all periods from July 19, 2012 reflect the results of the combined company. Unless specifically noted otherwise, as used throughout these consolidated financial statements, the term “Company” refers to the combined company after the Merger, and the business of I/P before the Merger. The terms I/P and Vringo refer to such entities’ standalone businesses prior to the Merger.

I/P (a development stage company) was incorporated on June 8, 2011 (“Inception”) under the laws of Delaware as Labrador Search Corporation.

Based on current operating plans, the current resources of the Company are expected to be sufficient for at least the next twelve months. The Company may choose to raise additional funds in connection with any future acquisition of additional intellectual property assets, operating businesses or other assets that it may choose to pursue. There can be no assurance, however, that any such opportunities will materialize. Moreover, any potential financing would likely be dilutive to the Company’s stockholders.

As of March 31, 2013, approximately $448 and $31 of the Company's net assets were located in Israel and Germany, respectively. In addition, the Company owns patents issued outside of the United States.
