PATENT RELATED INCOME

3. PATENT RELATED INCOME

The composition of patent related income in 2018 and 2017 was as follows:

Years ended December 31, 2018 and 2017. We had $0.1 million and $1.6 million of income from a patent arrangement in 2018 and 2017, respectively. We entered into an arrangement with an unaffiliated third party in 2010 under which we assigned certain patents in return for royalties on proceeds from patent monetization efforts by the third party. Such third party has engaged in various patent monetization activities, including enforcement, litigation and licensing. The party reported and we recorded $0.1 million and $1.6 million of income from this arrangement in the years ended December 31, 2018 and 2017, respectively.
