General [Abstract]

General

Note 1. General

Vringo, Inc., together with its consolidated subsidiaries (the “Company”), is engaged in the development and monetization of intellectual property worldwide. The Company's intellectual property portfolio consists of over 600 patents and patent applications covering telecom infrastructure, internet search and mobile technologies. The Company’s patents and patent applications have been developed internally and / or acquired from third parties. Prior to December 31, 2013, the Company operated a global platform for the distribution of mobile social applications and the services that it developed.

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.

Immediately following the Merger, approximately 67.61% of the combined company was owned by I/P stockholders on a fully diluted basis, and as a result of this and 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 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 or Legal Parent refer to such entities’ standalone businesses prior to the Merger.

On February 18, 2014, the Company executed the sale of its mobile social application business to InfoMedia Services Limited (“Infomedia”), in exchange for an 8.25% ownership interest (refer to Note 5).

Accounting Policies [Abstract]

Accounting and Reporting Policies

Note 2. Accounting and Reporting Policies

(a) Basis of presentation and principles of consolidation

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. GAAP. These consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes for the year ended December 31, 2013 included in the Company's Annual Report on Form 10-K. The results of operations for the three month period ended March 31, 2014 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.

b) Use of estimates

The preparation of accompanying consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses for the periods presented. Actual results may differ from such estimates. Significant items subject to such estimates and assumptions include the valuation of the assets acquired and the liabilities assumed as part of the Merger, the useful lives of the Company’s tangible and intangible assets, the valuation of the Company’s derivative warrants, the valuation of stock-based compensation, the valuation of goodwill, deferred tax assets and liabilities, income tax uncertainties and other contingencies.

(c) Development stage enterprise

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

(d) Translation into U.S. dollars

The Company conducts significant transactions in foreign currencies, which are recorded at the exchange rate as of the transaction date. All exchange gains and losses occurring from the remeasurement of monetary balance sheet items denominated in non-dollar currencies are reflected as non-operating income or expense in the consolidated statements of operations.

(e) Cash and cash equivalents

The Company invests its cash in 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. All highly liquid investments with original maturities of three months or less at acquisition date are considered cash equivalents.

(f) Derivative instruments

The Company recognizes all derivative instruments as either assets or liabilities in the consolidated balance sheets at their respective fair values. The Company's derivative instruments include its Special Bridge Warrants, Conversion Warrants, Preferential Reload Warrants and certain of its Series 1 Warrants (as defined in Note 8), all of which have been recorded as a liability at fair value, and are revalued at each reporting date, with changes in the fair value of the instruments included in the consolidated statements of operations as non-operating income (expense).

(g) Revenue recognition

Revenue from patent licensing and enforcement is recognized if collectability is reasonably assured, persuasive evidence of an arrangement exists, the sales price is fixed or determinable and delivery of the service has been rendered. The Company uses management's best estimate of selling price for individual elements in multiple-element arrangements, where vendor specific evidence or third party evidence of selling price is not available.

Currently, the Company’s revenue arrangements provide for the payment of contractually determined fees and other consideration for the grant of certain intellectual property rights related to the Company’s patents. These rights typically include some combination of the following: (i) the grant of a non-exclusive, retroactive and future license to manufacture and/or sell products covered by patents, (ii) the release of the licensee from certain claims, and (iii) the dismissal of any pending litigation. The intellectual property rights granted typically extend until the expiration of the related patents. Pursuant to the terms of these agreements, the Company has no further obligation with respect to the grant of the non-exclusive retroactive and future licenses, covenants-not-to-sue, releases, and other deliverables, including no express or implied obligation on the Company’s part to maintain or upgrade the related technology, or provide future support or services. Generally, the agreements provide for the grant of the licenses, covenants-not-to-sue, releases, and other significant deliverables upon execution of the agreement, or upon receipt of the upfront payment. As such, the earnings process is complete and revenue is recognized upon the execution of the agreement, upon receipt of the upfront fee, and when all other revenue recognition criteria have been met.

(h) Operating legal costs

Operating legal costs mainly include the costs and expenses incurred in connection with the Company’s patent licensing and enforcement activities, patent-related legal expenses paid to external patent counsel (including contingent legal fees), licensing and enforcement related research, consulting and other expenses paid to third parties, as well as internal payroll expenses and stock-based compensation.

(i) Recently Issued Accounting Pronouncements

In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which provides guidance on the presentation of unrecognized tax benefits. This guidance requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows: to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This guidance is effective beginning January 1, 2014 and is to be applied prospectively with retroactive application permitted. The Company adopted this guidance as of January 1, 2014, as required. There was no material impact of the consolidated financial statements resulting from the adoption.

In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This guidance changes the criteria for reporting a discontinued operation while enhancing disclosures in this area. This standard will be effective for the Company beginning January 1, 2015. Early adoption of the standard is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

(j) Reclassification

Certain balances have been reclassified to conform to presentation requirements including discontinued operations.

Computation of Net Loss per Common Share

Earnings Per Share, Basic and Diluted [Abstract]

Computation of Net Loss per Common Share

Note 3. Computation of Net Loss per Common Share

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. However, as the Company generated net losses in all periods presented, some potentially dilutive securities, that relate to the continuing operations, including certain warrants and stock options, were not reflected in diluted net loss per share, because the impact of such instruments was anti-dilutive. The table below presents the computation of basic and diluted net losses per common share:

	Three months ended March 31,				Cumulative from June 8, 2011 (Inception) through

Diluted net loss per common stock share	$	(0.13)	$	(0.15)	$	(1.64)

Net loss per share data presented excludes from the calculation of diluted net loss the following potentially dilutive securities, as they had an anti-dilutive impact:
Both vested and unvested options at $0.96-$5.50 exercise price, to purchase an equal number of shares of common stock of the Company		10,331,409		11,583,888		10,331,409

Business Combination

Note 4. 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, options, preferred stock 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 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 (refer to Note 8). 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 Accounting Standards Codification (“ASC”) 805, Business Combinations. 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.

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 by the Company using an income approach valuation model. 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 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. Goodwill recognized is not deductible for income tax purposes.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Assets Held for Sale and Discontinuing Operations

Note 5. Discontinued Operations and Assets Held For Sale

On December 31, 2013, the Company entered into a definitive asset purchase agreement with Infomedia for the sale of all assets and the assignment of all agreements related to the Company’s mobile social application business. The closing of the transaction, which was subject to the satisfaction or waiver of certain conditions, occurred on February 18, 2014 (“Closing”).

Upon Closing, in exchange for the assets and agreements related to the Company’s mobile social application business, the Company received 18 Class B shares of Infomedia, which represent an 8.25% ownership interest in Infomedia. Additionally, the Company’s CEO was appointed as a full voting member on Infomedia’s board of directors and the Company received a number of customary protective and anti-dilution rights. The Infomedia Class B shares were accounted for as a cost-method investment at the carrying amount of $787 and are included in Other assets in the consolidated balance sheet as of March 31, 2014. During the quarter ended March 31, 2014, there were no events or changes in circumstances that would indicate that the carrying amount of this investment may no longer be recoverable.

In connection with the asset purchase agreement, a non-cash impairment loss of $7,253 was recorded during the fourth quarter of 2013 and the requirement to report the results of the Company’s mobile social application business as discontinued operations was triggered. The following table represents the components of operating results from discontinued operations, as presented in the consolidated statements of operations:

	Three months ended March 31,				Cumulative from Inception through March 31,
	2014		2013		2014

Fair Value Measurements [Abstract]

Fair Value Measurements

Note 7. Fair Value Measurements

The Company measures fair value in accordance with FASB ASC 820-10, Fair Value Measurements and Disclosures. FASB 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, FASB ASC 820-10 establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

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

Level 2: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

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 following table presents the placement in the fair value hierarchy of liabilities measured at fair value on a recurring basis as of March 31, 2014 and December 31, 2013:

			Fair value measurement at reporting date using
			Quoted prices in
			active markets		Significant other	Significant
			for identical		observable	unobservable
Derivative warrant liabilities	Balance		assets (Level 1)		inputs (Level 2)	inputs (Level 3)
As of March 31, 2014	$	4,413		—	—	$	4,413
As of December 31, 2013	$	4,083		—	—	$	4,083

The Company measures its derivative liabilities at fair value. The Special Bridge Warrants, Conversion Warrants, Preferential Reload Warrants and the derivative Series 1 Warrants (as defined in Note 8) are classified within Level 3 because they are valued using the Black-Scholes-Merton and the Monte-Carlo models (as these warrants include down-round protection clauses), which utilize significant inputs that are unobservable in the market.

The following table presents the placement in the fair value hierarchy of assets that are measured at fair value on a non-recurring basis as of December 31, 2013 (there were no such assets or liabilities as of March 31, 2014):

In addition to the above, the Company’s financial instruments as of March 31, 2014 and December 31, 2013 consisted of cash, cash equivalents, receivables, 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 on a recurring basis using significant unobservable inputs (Level 3) during the period from Inception through March 31, 2014:

Valuation processes for Level 3 Fair Value Measurements

Fair value measurement of the derivative warrant liabilities related to the Special Bridge Warrants, Conversion Warrants, Preferential Reload Warrants and Series 1 Warrants (as defined in Note 8) 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,	Black-Scholes-Merton and the	Volatility	40.59% – 50.29%
Preferential Reload Warrants and the outstanding	Monte-Carlo models	Risk free interest rate	0.09% – 1.05%
derivative Series 1 Warrants		Expected term, in years	0.75 – 3.30
		Dividend yield	0%
		Probability and timing of down-round triggering event	5% occurrence in December 2014

The fair value of the assets held for sale as of December 31, 2013 (refer to Note 5) was determined by estimating the present value of the expected future cash flows associated with that asset or asset group by using certain unobservable market inputs. These inputs included discount rates, estimated future cash flows and certain continuing growth rate assumptions. The discount rates are intended to reflect the risk inherent in the projected future cash flows generated by the respective asset or asset group. The inputs used in the valuation were sensitive to certain factors related to mobile social application technology such as rapid changes in the industry and technological advances.

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 price, the Company’s assumptions 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, an increase in the market price of the Company’s common stock, an increase in the volatility of the Company’s shares of common stock, 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. Such changes would increase the associated liability while decreases in these assumptions would decrease the associated liability. 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, and does not plan to, declare dividends on its common stock, and as such, there is no change in the estimated fair value of the warrants due to the dividend assumption.

- Definition

Cancelled, 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.

On July 19, 2012, following the Merger with the Legal Parent, the Company’s stockholders approved the 2012 Employee, Director and Consultant Equity Incentive Plan (“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 Company’s 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, 2014, 3,647,837 shares were available for future grants under the 2012 Plan.

(d) Warrants

The following table summarizes information about warrant activity for the three month period ended March 31, 2014:

	No. of warrants	Weighted average exercise price		Exercise price range
Outstanding at January 1, 2014	18,427,478	$	3.15	$	0.94 – $5.06
Exercised	(718,766)	$	1.76	$	1.76
Outstanding at March 31, 2014	17,708,712	$	3.21	$	0.94 – $5.06

The Company’s outstanding warrants consisted of the following:

(1) Series 1 and Series 2 Warrants

As part of the Merger, on July 19, 2012, the Legal Parent issued to I/P’s stockholders 8,299,115 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 initially 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.

As part of the issuance of October 2012 Warrants, the down-round protection clause in 2,173,852 then outstanding Series 1 Warrants was removed. Because such warrants were no longer subject to down-round protection they were re-measured at fair value and classified as equity instruments. The overall impact of the removal of the down-round warrant protection, which was not material, was recorded during the year ended December 31, 2013. As a result, during the year ended December 31, 2013, the Company recorded an additional non-operating expense of $1,617, and re-classified $3,918 from derivative warrant liabilities to stockholders’ equity.

During the quarter ended March 31, 2014, 328,760 Series 1 Warrants and 352,532 Series 2 Warrants were exercised. From Inception and through March 31, 2014, 5,150,307 Series 1 Warrants and 1,678,592 Series 2 Warrants were exercised.

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

On July 19, 2012, the date of the Merger, the 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 quarter ended March 31, 2014, 37,474 non-Preferential Reload Warrants were exercised. During the period from Inception through March 31, 2014, 127,192 Special Bridge Warrants and 86,954 Conversion Warrants were exercised. From Inception and through March 31, 2014, 216,994 non-Preferential Reload Warrants and 726,721 Preferential Reload Warrants were exercised.

(3) Initial Public Offering Warrants

Upon completion of its initial public offering, in June 2010, 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, 2014, all of these warrants were outstanding and classified as equity instruments.

(4) 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, 2014, all October 2012 warrants were outstanding.

- Definition

Revenue from Settlement and Licensing Agreement [Abstract]

Revenue from Settlement and Licensing Agreement

Note 9. Revenue from Settlement and Licensing Agreement

On May 30, 2013, the Company’s subsidiary entered into a settlement and license agreement with Microsoft Corporation to resolve its patent litigation pending in the U.S. District Court for the Southern District of New York (I/P Engine, Inc. v. Microsoft Corporation, Case No. 1:13-cv-00688 (SDNY)). According to the agreement, Microsoft Corporation paid the Company $1,000 and agreed to pay 5% of any future amount Google pays for its use of the patents acquired from Lycos. The parties also agreed to a limitation on Microsoft Corporation's total liability, which would not impact the Company unless the amounts received from Google substantially exceed the judgment previously awarded. In addition, the parties also entered into a patent assignment agreement, pursuant to which Microsoft Corporation assigned six patents to I/P Engine. The assigned patents relate to telecommunications, data management, and other technology areas.

Commitments and Contingencies

Mar. 31, 2014

Commitments and Contingencies [Abstract]

Commitments and Contingencies

Note 10. Commitments and Contingencies

(a) Litigation and legal proceedings

The Company retains the services of professional service providers, including law firms that specialize in intellectual property licensing, enforcement and patent law. These service providers are often retained on an hourly, monthly, project, contingent or a blended fee basis. In contingency fee arrangements, a portion of the legal fee is based on predetermined milestones or the Company’s actual collection of funds. The Company accrues contingent fees when it is probable that the milestones will be achieved and the fees can be reasonably estimated.

The Company’s subsidiaries have filed patent infringement lawsuits against the subsidiaries of ZTE Corporation in the United Kingdom, France, Germany, Australia, India, and Brazil and against ASUSTeK Computer, Inc. and ASUS Computer GmbH in Germany, Spain and India. In such jurisdictions, an unsuccessful plaintiff may be required to pay a portion of the other party’s legal fees. Pursuant to negotiation with ZTE’s United Kingdom subsidiary, the Company placed two written commitments, in November 2012 and May 2013, to ensure payment should a liability by Vringo Infrastructure arise as a result of the two cases it has filed. The defendants estimated the total possible liability to be no more than approximately $2,900 for each case. In addition, ZTE's German subsidiary started three revocation (invalidity) proceedings against the Company; two in the first half of 2013 and one in the first quarter of 2014. Should ZTE be successful in any of those actions, the Company would liable for some portion of ZTE’s fees. The total amount the Company would have to pay is a statutorily determined percentage based on the estimated the value in dispute for these proceedings. ZTE has estimated the value of the revocation proceeding at approximately $1,700 for each of the three revocation cases on file; the Company assesses the likelihood of such payment as remote. The value of each of the four infringement proceedings against ZTE on file and of each of the two infringement proceedings against ASUS on file has been estimated at approximately $1,400 by the Company. On May 5, 2014, the Company deposited a bond of approximately $1,400 to allow it to enforce an injunction against ZTE. Should the injunction be successfully overturned on appeal, the Company may be obligated to compensate ZTE for any damages allegedly suffered as a result of the enforcement of the injunction, which would be ascertained through separate damages proceedings. Should the judgment which granted the injunction be affirmed on appeal, however, the amount paid as security would be returnable to the Company in full.

Pursuant to negotiations with ZTE’s Australian subsidiary, the Company placed a written commitment in April 2014 to ensure payment should a liability by Vringo Infrastructure arise as a result of the case filed. The amount of such commitment cannot be reasonably estimated at this time and the Company assesses the likelihood of such payment as remote. In addition, in Brazil as a condition of the relief requested, the Company deposited approximately $900 as a surety against the truth of allegations contained in the complaint. Unless ZTE is the prevailing party and proves that actual material damages were suffered while the requested relief was in place, the funds are returnable at the end of the litigation.

In addition, the Company may be required to grant additional written commitments, as necessary, in connection with its commenced proceedings against ZTE Corporation and its subsidiaries in various countries. It should be noted, however, that if the Company were successful on any court applications or the entirety of any litigation, ZTE Corporation would be responsible for a substantial portion of the Company’s legal fees.

(b) Leases

In July 2012, the Company signed a rental agreement for its corporate executive office in New York for an annual rental fee of approximately $137 (subject to certain adjustments) which was to expire in September 2015. However in January 2014, the Company entered into an amended lease agreement with the landlord for a different office space within the same building. The initial annual rental fee for this new office is approximately $403 (subject to certain future escalations and adjustments) beginning when the new office space is available which is expected to be the third quarter of 2014. This lease will expire five years and three months after the new office space is available. Rent expense for operating leases for the quarters ended March 31, 2014, and 2013, and cumulative from Inception until March 31, 2014 was $112, $53 and $473, respectively.

Risks and Uncertainties

Mar. 31, 2014

Risks and Uncertainties [Abstract]

Risks and Uncertainties

Note 11. 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)

The patents owned by the Company are presumed to be valid and enforceable. As part of the Company’s ongoing legal proceedings, the validity and/or enforceability of its patents is often challenged in a court or an administrative proceeding. To date, none of the Company’s patents have been declared to be invalid or unenforceable.

(c)

Financial instruments which potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents. The Company maintains its cash and cash equivalents with various major financial institutions. These major financial institutions are located in the United States 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 foreign currencies. 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.

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
