PATENTS

Acacia’s only identifiable intangible assets at September 30, 2015 and December 31, 2014 are patents and patent rights.  Patent-related accumulated amortization totaled $206,519,000 and $166,565,000 as of September 30, 2015 and December 31, 2014, respectively.

Acacia’s patents have remaining estimated economic useful lives ranging from one to nine years.  The weighted-average remaining estimated economic useful life of Acacia’s patents is approximately six years.  The following table presents the scheduled annual aggregate amortization expense as of September 30, 2015 (in thousands):

For the nine months ended September 30, 2015 and 2014, Acacia paid patent related investment costs, including up-front patent portfolio advances and previously accrued milestone payments related to patent related investments made in prior periods, totaling $19,504,000 and $24,518,000, respectively.  The underlying patents have estimated economic useful lives of approximately two to ten years.

During the nine months ended September 30, 2014, certain Acacia operating subsidiaries elected to sell their rights to patent portfolios, resulting in the acceleration of amortization expense for the patent-related assets totaling $2,702,000. Proceeds from the sale of patents and the related gain on sale for the nine months ended September 30, 2014 were $3,500,000 and $833,000, respectively. Included in amortization of patents for the nine months ended September 30, 2015 and 2014, was accelerated amortization related to the full or partial write-down of patent portfolios, due primarily to a reduction in expected estimated future net cash flows, totaling $258,000 and $2,565,000, respectively.
