From our inception through December 21, 2011, December 21, 2011 On March 26, 2015, two over 50 September 2015, In the Merger, Prism ’s former members received an aggregate of $16.5 3.5 $49.5 Our future revenues, if any, are expected to consist of royalties from licensing our patents and damages for past infringement of our patents. In addition to general and administrative expenses, we expect to incur expenses associated with patent infringement litigation, including contingency fees arrangements with our attorneys and revenue sharing payments to third The accompanying financial statements have been prepared under the assumption that the Company will continue to operate as a going concern, which contemplates the realization of assets and the settlement of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts of liabilities that may We have incurred operating losses since our inception and have a working capital deficiency as of December 31, 2016.

Notes to Financial Statements
Significant Accounting Policies [Text Block]	2. Summary of Significant Accounting Policies Basis of presentation The Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, Goldrush Insurance Services, Inc. and Prism. All significant inter-company accounts and transactions have been eliminated in the Consolidated Financial Statements. The Company recognizes in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the balance sheet. For non-recognized subsequent events that must be disclosed to keep the financial statements from being misleading, an entity is required to disclose the nature of the event as well as an estimate of its financial effect, or a statement that such an estimate cannot be made. Use of estimates The preparation of financial statements in conformity with generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash, cash equivalents and short-term investments The Company considers all highly liquid investments with original maturities of three three one Revenue recognition In general, patent licensing arrangements are expected to provide for the payment of contractually determined fees in consideration for the grant of certain intellectual property rights for patented technologies owned or controlled by the Company. Complex revenue arrangements may The Company recognizes revenue when (i) persuasive evidence of a contractual arrangement between the Company and the licensee exists, which create legally enforceable rights and obligations, (ii) the license agreement is delivered to the licensee, based upon the point at which control of the license transfers to the licensee, (iii) the price to the licensee is fixed or determinable and represents the amount of consideration to which the Company expects to be entitled to in exchange for transferring the license agreement to a licensee, and (iv) the collectability of consideration to which the Company is entitled to is reasonably assured. Business Combination Accounting We account for acquisitions in accordance with ASC 805 “Business Combinations.” March 26, 2015 may one first, ’s operations are included in the Company’s Consolidated Financial Statements as of the Closing Date. Acquisition related costs associated with a business combination are expensed as incurred. Intangible Assets The fair value amount assigned to each acquired patent asset is being amortized on a straight-line basis, depending on the patent, over a period ranging from 1.5 6.5 4.8 100% The amortization period of the covenants not to compete with Prism ’s officers is three The Company evaluates the recoverability of its long-lived assets, including intangible assets subject to amortization in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 360, Property, Plant and Equipment 360 may The Company recorded impairment charges for the years ended December 31, 2016 2015 $2.2 $23.8 he fair value of the acquired intangible assets were based on estimated future cash flows to be generated from the patent portfolio to be received from Prism by the Company, discounted using a rate commensurate with the risk involved. See Note 7 Goodwill Goodwill represents the excess of: (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of the Company’s previously held equity interest in the acquiree (if any), over (b) the fair value of assets acquired and liabilities assumed. Goodwill, deemed to have an indefinite life is subject to periodic impairment testing as described below. Goodwill is tested for impairment on a periodic basis, and at least annually in the fourth first second second In addition, the Company would evaluate goodwill for impairment if events or circumstances change between annual tests indicating a possible impairment. Examples of such events or circumstances include the following: ● a significant adverse change in legal factors or in the business climate; ● a more likely than not expectation that a segment or a significant portion thereof will be sold; or ● the testing for recoverability of a significant asset group within the segment. Derivative instruments We assess whether activities which provide capital to fund our operations include embedded features that are derivatives instruments. If a derivative instrument is embedded, the instrument is accounted for separately from the host contract. Changes in fair value are recognized in other income or loss, consistent with the underlying derivative instrument. As a result, any change in the value of our derivative instrument would be substantially offset by an opposite change in the value of the underlying derivative item. We do not use derivative instruments for trading or speculative purposes. Since this activity is not part of our normal course of business, we consider the risk in this area to be low. Concentration of risk —credit Financial instruments that potentially subject the Company to concentrations of credit risk, as defined by ASC 825, Financial Instruments may The Company ’s cash equivalents and investments consist of diversified investment grade securities. Our investment policy limits the amount of credit exposure to investments in any one During the years ended December 31, 201 6 2015, Share-Based Payments The Company accounts for share-based compensation in accordance with ASC 718 “Compensation – Stock Compensation.” 718, may The Company recognizes compensation costs for stock-based payments to employees and our board of directors, based on their grant-date fair value on a straight-line approach over the service period for which such awards are expected to vest. The fair value of stock options granted pursuant to our 1997 2008 model. The determination of fair value is affected by our stock price, as well as assumptions regarding subjective and complex variables such as expected employee exercise behavior and our expected stock price volatility over the expected term of the award. Generally, our assumptions are based on historical information and judgment is required to determine if historical trends may Expected term. The expected term represents the period that our share-based awards are expected to be outstanding. Our expected term was determined based on historical experience of similar awards, giving consideration to the contractual terms of the share-based awards, vesting schedules and expectations of future employee behavior. Expected volatility. We use the trading history of its common stock in determining an estimated volatility factor when using the Black-Scholes option-pricing formula to determine the fair value of options granted. Risk-free interest rate. We base the risk-free interest rate used in the BSM option-pricing model on the implied yield currently available on U.S. Treasury zero Expected dividend. We have not paid any cash dividend, nor do we expect to pay future dividends on our capital stock other than the special distribution of $5.00 March 9, 2012 zero Estimated forfeitures. ASC 718 Employee stock-based compensation expense is calculated based on awards ultimately expected to vest and is reduced for estimated forfeitures. Forfeitures are revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates and an adjustment to stock-based compensation expense will be recognized at that time. Changes to our underlying stock price, our assumptions used in the BSM option-pricing model calculation and our forfeiture rate, as well as future equity granted or assumed through acquisitions could significantly impact the compensation expense we recognize. Income taxes Under the asset and liability method prescribed under ASC 740, “Income Taxes,” Current accounting standards in the United States prescribe a recognition threshold and measurement of a tax position taken or expected to be taken in an enterprise's tax returns. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of presentation The Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, Goldrush Insurance Services, Inc. and Prism. All significant inter-company accounts and transactions have been eliminated in the Consolidated Financial Statements. The Company recognizes in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the balance sheet. For non-recognized subsequent events that must be disclosed to keep the financial statements from being misleading, an entity is required to disclose the nature of the event as well as an estimate of its financial effect, or a statement that such an estimate cannot be made.
Use of Estimates, Policy [Policy Text Block]	Use of estimates The preparation of financial statements in conformity with generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash, cash equivalents and short-term investments The Company considers all highly liquid investments with original maturities of three three one
Revenue Recognition, Policy [Policy Text Block]	Revenue recognition In general, patent licensing arrangements are expected to provide for the payment of contractually determined fees in consideration for the grant of certain intellectual property rights for patented technologies owned or controlled by the Company. Complex revenue arrangements may The Company recognizes revenue when (i) persuasive evidence of a contractual arrangement between the Company and the licensee exists, which create legally enforceable rights and obligations, (ii) the license agreement is delivered to the licensee, based upon the point at which control of the license transfers to the licensee, (iii) the price to the licensee is fixed or determinable and represents the amount of consideration to which the Company expects to be entitled to in exchange for transferring the license agreement to a licensee, and (iv) the collectability of consideration to which the Company is entitled to is reasonably assured.
Business Combinations Policy [Policy Text Block]	Business Combination Accounting We account for acquisitions in accordance with ASC 805 “Business Combinations.” March 26, 2015 may one first, ’s operations are included in the Company’s Consolidated Financial Statements as of the Closing Date. Acquisition related costs associated with a business combination are expensed as incurred.
Intangible Assets, Finite-Lived, Policy [Policy Text Block]	Intangible Assets The fair value amount assigned to each acquired patent asset is being amortized on a straight-line basis, depending on the patent, over a period ranging from 1.5 6.5 4.8 100% The amortization period of the covenants not to compete with Prism ’s officers is three The Company evaluates the recoverability of its long-lived assets, including intangible assets subject to amortization in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 360, Property, Plant and Equipment 360 may The Company recorded impairment charges for the years ended December 31, 2016 2015 $2.2 $23.8 he fair value of the acquired intangible assets were based on estimated future cash flows to be generated from the patent portfolio to be received from Prism by the Company, discounted using a rate commensurate with the risk involved. See Note 7
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill Goodwill represents the excess of: (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of the Company’s previously held equity interest in the acquiree (if any), over (b) the fair value of assets acquired and liabilities assumed. Goodwill, deemed to have an indefinite life is subject to periodic impairment testing as described below. Goodwill is tested for impairment on a periodic basis, and at least annually in the fourth first second second In addition, the Company would evaluate goodwill for impairment if events or circumstances change between annual tests indicating a possible impairment. Examples of such events or circumstances include the following: ● a significant adverse change in legal factors or in the business climate; ● a more likely than not expectation that a segment or a significant portion thereof will be sold; or ● the testing for recoverability of a significant asset group within the segment.
Derivatives, Embedded Derivatives [Policy Text Block]	Derivative instruments We assess whether activities which provide capital to fund our operations include embedded features that are derivatives instruments. If a derivative instrument is embedded, the instrument is accounted for separately from the host contract. Changes in fair value are recognized in other income or loss, consistent with the underlying derivative instrument. As a result, any change in the value of our derivative instrument would be substantially offset by an opposite change in the value of the underlying derivative item. We do not use derivative instruments for trading or speculative purposes. Since this activity is not part of our normal course of business, we consider the risk in this area to be low.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration of risk —credit Financial instruments that potentially subject the Company to concentrations of credit risk, as defined by ASC 825, Financial Instruments may The Company ’s cash equivalents and investments consist of diversified investment grade securities. Our investment policy limits the amount of credit exposure to investments in any one During the years ended December 31, 201 6 2015,
Compensation Related Costs, Policy [Policy Text Block]	Share-Based Payments The Company accounts for share-based compensation in accordance with ASC 718 “Compensation – Stock Compensation.” 718, may The Company recognizes compensation costs for stock-based payments to employees and our board of directors, based on their grant-date fair value on a straight-line approach over the service period for which such awards are expected to vest. The fair value of stock options granted pursuant to our 1997 2008 model. The determination of fair value is affected by our stock price, as well as assumptions regarding subjective and complex variables such as expected employee exercise behavior and our expected stock price volatility over the expected term of the award. Generally, our assumptions are based on historical information and judgment is required to determine if historical trends may Expected term. The expected term represents the period that our share-based awards are expected to be outstanding. Our expected term was determined based on historical experience of similar awards, giving consideration to the contractual terms of the share-based awards, vesting schedules and expectations of future employee behavior. Expected volatility. We use the trading history of its common stock in determining an estimated volatility factor when using the Black-Scholes option-pricing formula to determine the fair value of options granted. Risk-free interest rate. We base the risk-free interest rate used in the BSM option-pricing model on the implied yield currently available on U.S. Treasury zero Expected dividend. We have not paid any cash dividend, nor do we expect to pay future dividends on our capital stock other than the special distribution of $5.00 March 9, 2012 zero Estimated forfeitures. ASC 718 Employee stock-based compensation expense is calculated based on awards ultimately expected to vest and is reduced for estimated forfeitures. Forfeitures are revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates and an adjustment to stock-based compensation expense will be recognized at that time. Changes to our underlying stock price, our assumptions used in the BSM option-pricing model calculation and our forfeiture rate, as well as future equity granted or assumed through acquisitions could significantly impact the compensation expense we recognize.
Income Tax, Policy [Policy Text Block]	Income taxes Under the asset and liability method prescribed under ASC 740, “Income Taxes,” Current accounting standards in the United States prescribe a recognition threshold and measurement of a tax position taken or expected to be taken in an enterprise's tax returns.

Earnings Per Share, Policy [Policy Text Block]	Net loss per share Basic and diluted net income per share is computed using the weighted-average number of shares of common stock outstanding. Diluted earnings per share is a measure of the potential dilution that would occur if stock options had been exercised. The following table reconciles the denominator used to calculate basic and diluted net loss per share of common stock: Year Ended December 31, (In thousands) 201 6 201 5 Numerator for basic and diluted net loss per share: Net loss available to common stockholders: $ (12,788 ) $ (21,643 ) Denominator for net loss per share: Basic and diluted —weighted average shares of common stock outstanding 10,074 9,268 Net loss per share Basic and diluted as reported $ (1.27 ) $ (2.34 ) Potentially dilutive securities are not included in the diluted net income calculation, because we had a net loss from operations, net of tax.
