Revenue Recognition Under Agreement Description				the Company granted to the purchasers identified in the Senior Debt Agreement (the Revenue Participants) a right to receive a portion of the Monetization Revenues totaling $11,284,538 (the Revenue Stream).
Revenue Recognition of Participants Under Proportionate Share Agreement Description				The Revenue Participants proportionate share is equal to 75% of Monetization Net Revenues until $5,000,000 has been paid to the Revenue Participants, then 50% of Monetization Net Revenues until the remaining $6,284,538 has been paid to the Revenue Participants. All Revenue Stream Payments were to be payable on a monthly basis in arrears. The rights of the Revenue Participants to the Revenue Stream were secured by all of the Companys current patent assets and the cash collateral account, in each case junior in priority to the rights of the Note Purchasers. In connection with the Revenue Participants right to receive a portion of the Companys Monetization Revenues, the Company has recorded a net liability of $3,948,153, which represents the amount of the expected Monetization Revenues, discounted 18% over the expected life of the revenue share agreement. In conjunction with an amendment to the Senior Debt Agreement, as amended, dated March 1, 2016, the Company determined that the change in expected cash flows was greater than 10% as compared to the Senior Debt Agreement prior to such amendment and, therefore, a debt extinguishment was deemed to have occurred. When recording the new present value of the debt and revenue share, which was computed using a discount rate of 18%, a gain on debt extinguishment of $2,434,661 was recognized in the twelve-month period ended December 31, 2016. The Revenue Stream payment terms described in this paragraph have been superseded by the terms of the Restructuring Agreement upon the assignment of the Patents to INVT SPE in April 2017, as more fully explained below.

Debt Instrument, Description of Variable Rate Basis				LIBOR plus 7% (total interest rate of 8.69%). In addition, a 3% per annum paid-in-kind (PIK) interest will be paid by increasing the principal amount of the Senior Notes by the amount of such interest. The PIK interest shall be treated as principal of the Senior Notes for all purposes of interest accrual or calculation of any premium payment. In connection with the execution of the Senior Debt Agreement, the Company paid to the Note Purchasers a structuring fee equal to $385,000, which was accounted for as a discount on notes payable.

Contract Claims Description				the Company was required to apply, towards its obligations pursuant to the Senior Notes, 86% of the difference between (a) any revenues generated from the Monetization Revenue less (b) any litigation or licensing related third party expenses (including fees paid to the original patent owners) reasonably incurred by the Company to earn Monetization Revenue, subject to certain limits (such difference defined as Monetization Net Revenues). If Monetization Net Revenue was applied to outstanding principal of the Senior Notes (defined as Mandatory Prepayments), such Mandatory Prepayments were not subject to a prepayment premium. To the extent that any obligations under the Senior Notes were past due, including if such payments were past due as a result of an acceleration of the Senior Notes or certain conditions of breach or alleged breach had occurred, the percentage would have increased from 86% to 100%. The terms described in this paragraph have been superseded by the terms of the Restructuring Agreement upon the assignment of the Patents to INVT SPE in April 2017, as more fully explained below.
