Wi-LAN USA, Inc.

Wi-LAN USA, Inc. is a patent assertion entity and a subsidiary of Wi-LAN Inc., a technology development and intellectual property licensing company. Wi-LAN Inc., commonly known as WiLAN, was founded in 1992 and is headquartered in Ottawa, Ontario, Canada, with a U.S. headquarters in San Diego, California. WiLAN is a principal subsidiary of Quarterhill Inc., a publicly traded company on the Toronto Stock Exchange (TSX: QTRH) and OTCQX (OTCQX: QTRHF). As of 2021, WiLAN had 124 employees.

Originally, WiLAN developed wireless communication technologies, including Wideband Orthogonal Frequency Division Multiplexing (W-OFDM), which contributed to the 802.11a Wi-Fi standard. However, the company shifted its business model in 2006 to focus primarily on licensing intellectual property and patent rights, both from its internally developed portfolio and acquired patents. Its patent portfolios cover a diverse range of technology verticals, including wireless telecommunications (e.g., Bluetooth, LTE, WiMAX, WiFi, CDMA), semiconductor memory, microprocessors, semiconductor manufacturing, power management ICs, RF ICs, NFC, and wired connectivity like USB-C technologies. WiLAN describes itself as one of the most successful patent monetization companies globally.

Wi-LAN USA, Inc.'s patent litigation posture is that of a non-practicing entity (NPE) asserting acquired portfolios.

WiLAN also acquired a portfolio of approximately 2,000 patents from MediaTek Inc. in 2020, relating to technologies such as power management ICs, RF ICs, and embedded microcontrollers. Another subsidiary, IPA Technologies, a WiLAN entity, obtained a $242 million verdict against Microsoft over a patent related to voice assistant technology in 2024. These cases highlight WiLAN's strategy of asserting patents across various technology sectors and its history of significant litigation outcomes.
