​ In September 2021, the Company entered into an intellectual property monetization deal to sell five patents to a customer for a total contract value of $5.25 million. Two of the patents were assigned to the customer in September 2021, and the remaining three patents were assigned to the customer in October 2021. Control is transferred when the patents are assigned to the customer. As a result, all $5.25 million of patent revenue was recognized during the year ended December 31, 2021, related to the patent sales. There were no patent sales for the year ended December 31, 2022. The Company licenses its intellectual property and is entitled to consideration based on the customer’s sales. The Company makes estimates in instances when the customer reports sales on a lagged basis and actual information is not available timely. The estimates are based on historical trends in the customer’s activity and current market conditions. In the year ended December 31, 2022, the Company recognized $0.3 million of royalty revenue related to activity occurring in the year ended December 31, 2021. In the year ended December 31, 2021, the Company recognized $0.8 million of royalty revenue related to activity occurring in the year ended December 31, 2020. This is a change in estimate and is based on actual information received from the customer. The amounts are reported in licensing, royalty, patent and other revenue in the statements of income and comprehensive income. The Company recognizes revenue in three geographic regions: Asia-Pacific (APAC); North America; and Europe, Middle East and Africa (EMEA).
