General [Abstract]

General

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 patents and patent applications have been developed internally and acquired from third parties. Vringo is operating 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 December 31, 2012, approximately $565 and $33 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. As of December 31, 2011, all of the Company’s net assets were located in the United States.

Accounting Policies [Abstract]

Significant Accounting and Reporting Policies

Note 2 - Significant 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 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 December 31, 2012. 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 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 December 31, 2012	3.733	0.759
At December 31, 2011	3.821	0.774
Average exchange rate for the period from July 19, 2012 through December 31, 2012	3.860	0.778

(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 October 2012 (as defined in Note 10) 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 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.

(f) Derivative instruments

The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. The Company's derivative instruments include Special Bridge Warrants, Conversion Warrants, Preferential Reload Warrants and Series 1 Warrants, 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 statement of operations as non-operating income or expense.

(g) Property and equipment

Property and equipment is stated at historical cost, net of accumulated depreciation. Depreciation is calculated according to the straight-line method over the estimated useful lives of the assets. Annual depreciation rates are as follows:

	%
Office furniture and equipment		7-33
Computers and related equipment		33
Leasehold improvements		10

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

(h) Goodwill

Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is reviewed for impairment at least annually, and when triggering events occur, in accordance with the provisions of FASB ASC Topic 350, Intangibles - Goodwill and Other. The goodwill impairment test is a two-step test. Under the first step, the fair value of the reporting unit is compared with its carrying value (including goodwill). If the fair value of the reporting unit is less than its carrying value, an indication of goodwill impairment exists for the reporting unit and the entity must perform step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to an acquisition price allocation and the residual fair value after this allocation is the implied fair value of the reporting unit goodwill. Fair value of the reporting unit is determined using a discounted cash flow analysis. If the fair value of the reporting unit exceeds its carrying value, step two does not need to be performed. The Company performed its annual impairment review of goodwill as of December 31, 2012. As the fair value of reporting unit significantly exceeds carrying value, the Company did not recognize any impairment charges related to goodwill.

(i) Intangible assets

Intangible assets include acquired technology (see Note 5), recorded at fair value, and patents purchased, recorded based on the cost to acquire them. These assets are amortized over their remaining estimated useful lives. Useful lives of intangible assets are periodically evaluated for reasonableness and the assets are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may no longer be recoverable.

(j) Revenue recognition

Revenue from subscription services, software development and intellectual property is recognized if collection of the relevant receivable 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, the Company recognizes these up-front fees over the life time of the contract. According to ASU 2009-13, Revenue Recognition (Topic 605), the Company uses management's best estimate of selling price for individual elements in multiple-element arrangements, where other sources of evidence are unavailable.

(k) Cost of revenue

Cost of revenues mainly includes expenses incurred in connection with the Company’s patent enforcement activities, such as legal fees, consulting costs, patent maintenance and other related expenses, as well as, the amortization of acquired patents and technology. Legal costs incurred in connection with ongoing litigation are expensed as occurred. Cost of revenue also includes expenses directly related to providing mobile services in launched markets. In addition, these costs include royalty fees for content sales and amortization of prepaid content licenses. Cost of revenue does not include expenses related to product development, integration or support, as these are included in research and development and marketing, general and administrative expenses.

(l) Research and development

Research and development expenses are expensed as incurred and consist primarily of payroll and facilities charges associated with the research, development and integration of our current and future products.

(m) Accounting for stock-based compensation

Stock-based compensation is recognized as an expense in the financial statements and such cost is measured at the grant-date fair value of the equity-settled award. The fair value of stock options granted to consultants is estimated at the date of grant using the Black-Scholes-Merton option-pricing model. In cases where no measurement date has been reached as there is no counter-party performance nor performance commitment (sufficiently large disincentive for non-performance), the options are revalued at each reporting date. The expense is recognized using the straight-line method, over the requisite service period. The Company uses full contractual life to estimate the expected term of options granted to management and directors (and non-employees), as the Company expects such options to be exercised at the end of their life, and the simplified method to estimate the expected term of options granted to employees, due to insufficient history and high turnover in the past. The contractual life of options granted under the Legal Parent’s 2006 and 2012 option plans are 6 and 10 years, respectively.

(n) Income taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for the amount of deferred tax assets that, based on available evidence, are not more likely than not to be realized.

In assessing the need for a valuation allowance, the Company looks at cumulative losses in recent years, estimates of future taxable earnings, feasibility of tax planning strategies, the realizability of tax benefit carryforwards, and other relevant information. Valuation allowances related to deferred tax assets can be impacted by changes to tax laws, changes to statutory tax rates and future taxable earnings. Ultimately, the actual tax benefits to be realized will be based upon future taxable earnings levels, which are very difficult to predict. In the event that actual results differ from these estimates in future periods, the Company will be required to adjust the valuation allowance.

Significant judgment is required in evaluating the Company's federal, state and foreign tax positions and in the determination of its tax provision. Despite management's belief that the Company's liability for unrecognized tax benefits is adequate, it is often difficult to predict the final outcome or the timing of the resolution of any particular tax matters. The Company may adjust these accruals as relevant circumstances evolve, such as guidance from the relevant tax authority, its tax advisors, or resolution of issues in the courts. The Company's tax expense includes the impact of accrual provisions and changes to accruals that it considers appropriate. These adjustments are recognized as a component of income tax expense entirely in the period in which they are identified. The Company records interest related to unrecognized tax benefits in interest expense and penalties in selling, general, and administrative expenses.

The Company accounts for its income tax uncertainties in accordance with ASC Subtopic 740-10 which clarifies the accounting for uncertainties in income taxes recognized in a company's financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50 percent of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

(o) 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. However, as the Company generated net losses in all periods presented, some potentially dilutive securities, 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:

Diluted net loss per common stock share		(0.61	)		(0.33	)		(0.93	)

At December 31, 2012, the Company excluded from the calculation of its diluted net loss the following potentially dilutive securities, as they had an anti-dilutive impact: (i) 8,942,929 of both vested and unvested options at $0.96-$5.50 exercise price, to purchase 8,942,929 shares of common stock of the Company; (ii) 3,125,000 unvested Restricted Stock Units (“RSU”) to purchase 3,125,000 shares of common stock of the Company; (iii) 14,125 unvested $0.01 options to purchase 14,125 shares of common stock of the Company; (iv) 92,903 common stock shares granted, but not yet vested; (v) 3,060,907 Series 1 Warrants to purchase 3,060,907 shares of common stock of the Company; and (vi) 726,721 Preferential Reload Warrants to purchase 726,721 shares of common stock of the Company.

(p) Long lived assets

Long-lived assets, such as property and equipment and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is to be determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.

(q) Commitments and Contingencies

Liabilities for loss contingencies arising from assessments, estimates or other sources are to be recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs expected to be incurred in connection with a loss contingency are expensed as incurred.

(r) 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 to sell 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- 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 - 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.

(s) Impact of recently issued accounting standards

In December 2011, the FASB issued ASU No. 2011-11, Balance Sheet (Topic 210) “Disclosures about Offsetting Assets and Liabilities”. ASU 2011-11 requires an entity to disclose information about offsetting and related arrangements to enable users of financial statements to understand the effect of those arrangements on its financial position, and to allow investors to better compare financial statements prepared under U.S. GAAP with financial statements prepared under International Financial Reporting Standards (IFRS). The new standards are effective for annual periods beginning January 1, 2013, and interim periods within those annual periods. Retrospective application is required. The Company will implement the provisions of ASU 2011-11 as of January 1, 2013.

The Company does not expect the adoption of ASU No. 2011-11 to have a material impact on its financial position, results of operations, or cash flows.

In July 2012, the FASB issued ASU 2012-02, Balance Sheet (Topic 350) “Intangibles-Goodwill and Other”, which allows an organization to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test for indefinite-lived intangible assets. An organization that elects to perform a qualitative assessment is required to perform the quantitative impairment test for an indefinite-lived intangible asset if it is more likely than not that the asset is impaired. This is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted. The Company does not expect the adoption of ASU 2012-02 to have a material impact on its financial position, results of operations nor cash flows.

Acquired technology:

As also described in Note 8, the value allocated to technology, is being amortized over its estimated useful life. During the year ended December 31, 2012, total amortization expense of $763 was recorded.

Patents:

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. The grant fair value of the shares issued was $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 year ended December 31, 2012, and the period from Inception through December 31, 2011, total amortization expense of $2,455 and $328 was recorded. Estimated amortization expense for each of the five succeeding years, based upon intangible assets owned at December 31, 2012 is as follows:

On June 22, 2011, I/P issued a senior secured note payable, in the total amount of $3,200, to one of its principal stockholders, Hudson Bay Master Fund Ltd. (“Hudson Bay”) (the “Note”). The Note accrued interest at 0.46% per annum. After the Merger was consummated, on July 19, 2012, the Note was amended and restated and the holder was able to exercise any and all rights and remedies pursuant to such amended and restated Note, including with respect to any optional redemption provisions contained therein. The amended and restated Note was to mature on June 22, 2013 and I/P had granted Hudson Bay a security interest in all of its tangible and intangible assets, in order to secure I/P’s obligations under the senior secured note. After the consummation of the Merger, the Note became an obligation of the Company, as it is to guarantee I/P’s obligations. On August 15, 2012, the Company repaid in full the outstanding balance of the Note.

Series Convertible Preferred Stock [Abstract]

Series A Convertible Preferred Stock

Note 7 – 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.

Business Combinations [Abstract]

Business Combination

Note 8 - 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 (see also Note 10). 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

Measurement of consideration:

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 December 31, 2012, according to ASC 805, this purchase price allocation is provisional, as existing estimations are subject to change, in certain future events. Goodwill recognized is not deductible for income tax purposes. For the year ended December 31, 2012, the Company’s consolidated statements of operations include revenues attributable to the Legal Parent in the total amount of $269 and a net loss of $8,768. Had the acquisition taken place on June 8, 2011, the revenue in the consolidated statement of operations and the consolidated net loss would have been as follows:

	2012					2011
	Unaudited					Unaudited
	Revenue		Net Loss			Revenue		Net Loss
Year ended (in 2011, period from Inception through December 31, 2011)		593		(31,519	)		416		(8,527	)

Pro forma adjustment consists of amortization of acquired technology. The above pro forma disclosure excludes the possible impact of valuation of equity and derivative instruments valued in connection with the Merger. The amortization, net, for the year ended December 31, 2012 was $1,689. The amortization, net, for the period from Inception through December 31, 2011 was $952.

- 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).

The Special Bridge Warrants, Conversion Warrants, Preferential Reload Warrants and Series 1 Warrants (as they are defined in Note 10) 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 placement in the fair value hierarchy of assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2012 and 2011:

In addition to the above, the Company’s financial instruments at December 31, 2012 and December 31, 2011, consisted of cash, cash equivalents (at December 31, 2012 only) and accounts payable, as well as accounts receivable and long term deposits (at December 31, 2012 only). 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 year ended December 31, 2012 (as there was no such activity in 2011):

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 10) 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	65.96% – 68.01%
		Risk free interest rate	0.36% – 0.66%
		Expected term, in years	1.99 – 4.55
		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.

Stockholders' Equity Note [Abstract]

Stockholders' Equity

Note 10 – Stockholders' Equity

Pre-Merger common stock share amounts and balance sheet disclosures were retrospectively restated to reflect Vringo’s equity instruments after the Merger.

(a) Common Stock

The following table illustrates the grants of common stock and the sales of common stock at less than fair value made during the period from Inception through December 31, 2011:

Title	Grant, purchase or vest date	No. of shares		Total fair value at grant, purchase date		Amount paid for shares		Compensation recognized from Inception through December 31, 2011		Compensation recognized during the year ended December 31, 2012		Compensation not vested at December 31, 2012
Consultant	June 22, 2011		377,200		N/A	$	—	$	49	$	123	*$	268
Director and Officers	June – November 2011		8,390,814	$	828	$	—	$	400	**$	428	$	—
			8,768,014	$	828	$	—	$	449	$	551	$	268

Based on fair value of common stock of $2.87 at December 31, 2012. See also Note 2 (m).

Following the Merger, the vesting of shares of common stock with repurchase rights, granted in 2011, to I/P’s management and directors was fully accelerated. As a result of the acceleration, 2,702,037 shares previously issued became vested and a compensation expense of $294 was recorded, in addition to $134 recorded due to normal course of vesting.

The following table summarizes information about the Company's issued and outstanding common stock from Inception through December 31, 2012:

	Shares of common stock

(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 the I/P 2011 Plan was subject to adjustments for certain changes. As of December 31, 2011, 2,855,717 shares were available for future grant. 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, expire 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 December 31, 2012, an additional 7,031,895 shares are available for future grants under the 2012 Plan.

(c) Stock options and RSUs

In July 2012, following the consummation of the Merger, the vesting of 908,854 options granted to certain officers and directors of the Legal Parent was accelerated. In addition, on November 6, 2012, the vesting of all of the Legal Parent’s pre-Merger granted options outstanding (except for separation grants) was accelerated by 50%, as certain market conditions were met. As a result, an additional 221,626 options vested. Due to these accelerations, the Company recorded an additional expense of $1,509.

As of December 31, 2012, the total aggregate intrinsic value of options outstanding and options exercisable was $3,548 and $3,200, respectively. The total aggregate intrinsic value of options exercised was $2,417. As of December 31, 2011, the total aggregate intrinsic value of both the options outstanding and options exercisable was $0 and no options were exercised. The total fair value of stock options that vested in the year ended December 31, 2012, the period from Inception through December 31, 2011 and cumulative from Inception until December 31, 2012 amounts to $5,927, $25 and $5,952 respectively.

As of December 31, 2012, there was approximately $21,751 of total unrecognized share-based payment cost related to non-vested options, shares and RSUs, granted under the incentive stock option plans. Overall, the cost is expected to be recognized, on a straight line basis, over a 4 year period, or over a weighted average of 1.9 years.

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

(d) Warrants

The following table summarizes information about warrant activity for the year ended December 31, 2012:

	No. of warrants			Weighted average exercise price		Exercise price range
Outstanding at January 1, 2012	(a)	250,000		$	1.00		$1.00
Recorded pursuant to the Merger		22,695,411		$	2.45		$0.94 – $5.06

Exercised during the year		(7,082,150	)	$	1.73		$1.00 – $1.76
Outstanding at December 31, 2012		18,863,261		$	3.11		$0.94 – $5.06

The Company’s outstanding warrants consisted of the following:

(a) I/P Warrants

On August 30, 2011, I/P issued 250,000 warrants to purchase 250,000 shares of common stock of I/P, at an exercise price of $1.00 and a contractual life of 5 years (the “I/P Warrants”). On July 12, 2012, prior to the Merger, I/P Warrants were exercised in full; as a result, 754,400 shares of the Legal Parent’s common stock shares were issued to the warrant holders upon Merger.

(b) 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. Following the Merger and through December 31, 2012, 4,655,099 Series 1 Warrants and 1,280,870 Series 2 Warrants were exercised.

(c) 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 Special Bridge Warrants, at an exercise price of $0.94 per share, with a remaining contractual term of 2.44 years; (ii) 101,445 Conversion Warrants, at an exercise price of $0.94 per share, with a remaining contractual term of 2.44 years; (iii) 887,330 Preferential Reload Warrants, at an exercise price of $1.76 per share, with a remaining contractual term of 4.55 years; and (iv) 814,408 non-Preferential Reload Warrants, at an exercise price of $1.76 per share, with a remaining contractual term of 4.55 years. Following the Merger and through December 31, 2012, 169,520 non-Preferential Reload Warrants and 726,721 Preferential Reload Warrants were exercised.

(d) 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 December 31, 2012, all of these warrants were outstanding and classified as equity.

(e) 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%. 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.

Income Tax Disclosure [Abstract]

Income Taxes

Note 11 – Income Taxes

The components of loss before income taxes:

	For the year ended December 31, 2012			For the period from Inception through December 31, 2011			Cumulative from Inception through December 31, 2012
U.S.		(20,394	)		(2,754	)		(23,148	)
Non-U.S.		(392	)		—			(392	)
		(20,786	)		(2,754	)		(23,540	)

Income tax benefit (expense) attributable to the operating loss consists of the following:

	For the year ended December 31, 2012			For the period from Inception through December 31, 2011		Cumulative from Inception through December 31, 2012
U.S.
Current		(8	)		—		(8	)
Deferred		—			—		—

Non-U.S
Current		(104	)		—		(104	)
Deferred		57			—		57
		(55	)		—		(55	)

The total current income tax expense recorded for the year ended December 31, 2012, the period from Inception through December 31, 2011 and the cumulative period from Inception through December 31, 2012 was $112, $0 and $112, respectively. The total deferred income tax benefit recorded in the year ended December 31, 2012, the period from Inception through December 31, 2011 and the cumulative period from Inception through December 31, 2012 was $57, $0 and $57, respectively.

Income tax expense for the year ended December 31, 2012 and for the period from Inception through December 31, 2011 and for the cumulative period from Inception through December 31, 2012, differed from the amounts computed by applying the U.S. federal rate of 35% as follows:

	For the year ended December 31, 2012			For the period from Inception through December 31, 2011			Cumulative from Inception through December 31, 2012
Loss before income taxes		(20,786	)		(2,754	)		(23,540	)
Tax rate		35	%		35	%		35	%

Computed "expected" tax benefit		7,275			964			8,239
Foreign tax rate differential		(235	)		—			(235	)
Change in valuation allowance		(8,432	)		(1,231	)		(9,663	)
Nondeductible expenses		(15	)		—			(15	)
State and local income tax, net of federal income tax expense		1,326			—			1,326
Other items		26			267			293

Income tax expense		(55	)		—			(55	)

These deferred tax assets (liabilities) arise from the following types of temporary differences:

Deferred tax assets:	For the year ended December 31, 2012			For the period from Inception through December 31, 2011
Acquired patents (see also Note 5)		446			—
Liability for accrued employee vacation and severance pay		19			—
Deferred tax asset for stock based compensation		4,590			—
NOL		23,127			1,231
Total gross deferred tax assets		28,182			1,231

Less:
Valuation allowance		(24,274	)		(1,231	)
Deferred tax liability for acquired technology (see Note 8):		(3,889	)		—

Net deferred tax assets		19			—

The valuation allowance primarily relates to operating loss carryforwards ("NOL") that, in the judgment of management, are not more-likely-than-not to be realized. In assessing the realizability of deferred tax assets, management considers whether it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized. The following table presents the changes to valuation allowance during the periods presented:

As of Inception	—
Charged to cost and expenses		1,231

As of December 31, 2011		1,231
Charged to cost and expenses		10,803
Acquisitions *		12,240

As of December 31, 2012		24,274

* As mentioned above, the NOLs amounts are presented before Internal Revenue Code, Section 382 limitations.

The Israeli subsidiary has qualified as a "Beneficiary Enterprise" under the 2005 amendment to the Israeli Law for the Encouragement of Capital Investments, 1959 (the "Investment Law"). As a Beneficiary Enterprise, the Israeli subsidiary is entitled to receive future tax benefits which are limited to a period of seven years. The year in which a company elects to commence its tax benefits is designated as the year of election ("Year of Election"). The Israeli subsidiary has elected 2007 as its Year of Election and has received a two year tax holiday for profits accumulated in the years 2007-2008 and a reduced tax rate for the following five years. In 2011, the Israeli subsidiary irrevocably adopted an amendment to the Investment law, according to which the following uniform tax rates (applicable to the zone where the production facilities of the Israeli subsidiary are located) would apply: 15% in 2011 and 2012, 12.5% in 2013 and 2014, and 12% in 2015 and thereafter. As of the balance sheet date, the Israeli subsidiary believes that it is in compliance with the conditions of the Beneficiary Enterprise program. Income that is not derived from the Beneficiary Enterprise is subject to the regular corporate tax rate of 25% (as from 2012).

As of December 31, 2012, the Legal Parent and I/P have an aggregate total NOL for U.S. federal state and local purposes in the amount of approximately $55,728 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, the Company's initial public offering, financing activities, as well as the Merger with I/P (see also Note 8), may significantly limit the Legal Parent's ability to utilize such NOL and credit carryforwards, although the Company has not yet determined to what extent.

As part of the Merger purchase price allocation, the Company recorded a deferred tax liability in connection with the acquired technology (see also Note 8). This deferred tax liability was offset by a deferred tax asset in the same amount. The deferred tax asset in respect of the remaining operating loss carryforwards, as well as the other deferred tax assets in the U.S., has been offset by a valuation allowance as in the opinion of the Company's management it is more likely than not that the operating 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 they are more likely than not to be realized.

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

The Company did not have any material unrecognized tax benefits in 2012 and 2011. The Company does not expect to record any additional material provisions for unrecognized tax benefits within the next year.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Commitments and Contingencies [Abstract]

Commitments and Contingencies

Note 12 – Commitments and Contingencies

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 "Patents"). After finding that the asserted claims of the 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. After trial, I/P Engine and Defendants filed post-trial motions with the court. I/P Engine filed motions related to the issues of laches, damages, and post-judgment royalties, which is the one motion not fully briefed. The Defendants filed motions related to issues of non-infringement, invalidity and damages. The court has denied I/P Engine’s motion related to the issue of laches. The fully briefed motions are ripe for judicial determination. The court has indicated that after the currently-briefed motions are decided, the court may consider the issue of post-judgment royalties. According to certain scaled fee agreements, I/P Engine will pay between 15% and 20% of any recovery to professional service providers. In spite of the verdict, as of December 31, 2012, the Company did not record any revenue related to this litigation, as timing of collection, if any, or the amounts due to it, cannot be determined.

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, 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. As of December 31, 2012, the Company did not recognize any income (nor contingent expense) related to this litigation, other than from the AOL settlement.

On October 8, 2012, the Company’s subsidiary filed a patent infringement lawsuit against a subsidiary of ZTE Corporation in the United Kingdom. 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 4 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 years ended December 31, 2012, the period from Inception through December 31, 2011 and for the cumulative period from Inception until December 31, 2012, was $163, $11 and $174, respectively. Future minimum lease payments under non-cancelable operating leases for office space and cars, as of December 31, 2012, are as follows:

Year ending December 31,	Amount
2013		193
2014		146
2015		104

Risks and Uncertainties

Dec. 31, 2012

Risks and Uncertainties [Abstract]

Risks and Uncertainties

Note 13 - 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 the patents may be challenged in a court or administrative proceeding. To date, the Company’s patents have not 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 and accounts receivable. The Company maintains its cash and cash equivalents with various major financial institutions. These major financial institutions are located in the United States and Israel, and the Company’s policy is designed to limit exposure to any one institution. With respect to accounts receivable, the Company is subject to a concentration of credit risk, as a majority of its outstanding trade receivables relate to sales to a limited number of customers.

(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.

- Definition

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
