Other Liabilities	7. Other Liabilities On November 14, 2016, the Company entered into a Proceeds Investment Agreement (the “Agreement”) with Brickell Key Investments LP (“BKI”). Pursuant to the Agreement, BKI financed an aggregate of $13,500,000 in a patent purchase and monetization program to be implemented and managed by the Company (the “Financing”). Pursuant to the Agreement. $3,000,000 of the Financing was used to cover the Company’s purchase of a portfolio of U.S. and foreign LED patents and a license from Intellectual Discovery Co., Ltd., a Korean company (collectively, the “LED Patent Portfolio”), resulting in a basis in these assets of $0. A total of $6,000,000 of the Financing was directed by BKI to attorneys to cover anticipated attorneys’ fees and out-of-pocket expenses for legal proceedings that may transpire relating to enforcement of the LED Patent Portfolio. This amount is not included in the Company’s financial statements as the Company has no control over these funds, which are segregated and escrowed in the attorneys’ trust account. In addition, on November 14, 2016, the Company received $4,500,000 of the Financing, which was required to be used by the Company to pay for the defense of Inter Partes Review or other similar proceedings that may be filed from time to time by defendants with the U.S. Patent & Trademark Office relating to the LED Patent Portfolio, with excess amounts available for general working capital needs. As of September 30, 2018, an aggregate of approximately $2,385,000 is recorded as other liabilities by the Company, of which approximately $1,919,000 is classified as short-term. Of this amount, the Company allocated $2,500,000 which it subsequently adjusted to $1,500,000 for the payment of estimated future Inter Partes Review costs. The Company will reduce this liability as it pays legal and other expenses related to the Inter Partes Review matters involving the LED Patent Portfolio as incurred. The remaining $1,216,000 in other liabilities is allocated to working capital, which the Company is amortizing on a pro-rata basis over the expected remaining life of the monetization period of the LED Patent Portfolio through November 30, 2019. For this amount, the Company reduced the liability with an offset to selling, general and administrative costs by $47,500 per month from January 2017 through July 2017, $80,000 per month for the remainder of 2017 through March 2018, and $86,500 per month for the remainder of 2018. During the nine months ended September 30, 2018, there was approximately $300,000 of Inter Partes Review costs and an aggregate of $761,000 was recorded as a reduction of the liability allocated to working capital. On July 8, 2013, the Company’s subsidiary, DSSTM, purchased two patents for $500,000 covering certain methods and processes related to Bluetooth devices. In conjunction with the patent purchases, DSSTM entered into a Proceed Right Agreement with certain investors pursuant to which DSSTM initially received $250,000 of a total of $750,000 which it will ultimately receive thereunder, subject to certain payment milestones, in exchange for 40% of the proceeds which it receives, if any, from the use, sale or licensing of the two patents. As of September 30, 2018, the Company had received an aggregate of $650,000 ($650,000 in 2017) from the investors pursuant to the agreement of which approximately $376,000 was in current liabilities in the consolidated balance sheets ($432,000 as of December 31, 2017). The Company reduces the liability as it pays legal and other expenses related to its litigation involving the Bluetooth patents, for which the amount is available to be used for 50% of all such expenses. As described in Note 6, on February 13, 2014, DSSTM entered into an Investment Agreement with Fortress. Pursuant to this agreement, an aggregate of $459,000 of fixed and contingent equity interests received are recorded in current liabilities. The liabilities under the agreement matured on February 13, 2018. Per the agreement, the Investors have the right to take ownership of the patents as settlement of the liabilities upon maturity. On June 26, 2018, the parties entered into an agreement (see Note 6 “Other Debt”) which among other things eliminated the Company’s obligation for the fixed and contingent equity interests under the agreement.
