Item 2.02 Results of Operations and Financial Condition.

On February 21, 2018, RPX Corporation issued a press release announcing its financial results for the fourth quarter and year ended December 31, 2017. The full text of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

This information shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

Item 2.06 Material Impairment.

On February 21, 2018, RPX Corporation concluded that non-cash impairment losses of $94.1 million will be recorded in the financial information of the three months and fiscal year ended December 31, 2017, $89.0 million of which relates to goodwill in its discovery services segment and the remaining impairment is associated with its cost method investments in its patent risk management segment. RPX Corporation's conclusion on goodwill impairment was made in connection with its annual impairment testing of goodwill for its discovery services business which resulted in the carrying values exceeding the fair values primarily due to (1) decreased expected future cash flows from pricing pressures and competition in the discovery services marketplace as well as significant fluctuations due to the project-based nature of these cash flows, and (2) a decrease in estimated peer company values. No cash expenditures are anticipated as a result of the impairment losses.
