MOSAID Technologies Inc., headquartered in Ottawa, Ontario, Canada, is a private intellectual property (IP) management company. Founded in 1975, it originally operated as a semiconductor technology firm, designing Dynamic Random Access Memory (DRAM) chips and related test equipment. In 2011, the company was acquired by U.S.-based private equity firm Sterling Partners, after which it transitioned to exclusively focus on patent licensing. While it briefly operated under the name Conversant Intellectual Property Management Inc. from 2013, it reverted to MOSAID Technologies Inc. in April 2021. MOSAID maintains additional offices in Plano, Texas, and Palo Alto, California, and reportedly had approximately 56 employees as of 2023.
MOSAID's primary operation is the licensing, acquisition, and monetization of patents, primarily in semiconductor and communications technologies. It manages a substantial patent portfolio, which includes both its own historical innovations in DRAM and flash memory, as well as acquired patents from other companies. Notable acquisitions include a portfolio of approximately 2,000 wireless patents from Nokia in 2011, managed through its subsidiary Core Wireless S.a.r.l. The company is widely characterized as a Non-Practicing Entity (NPE) or Patent Assertion Entity (PAE).
Mosaid Technologies Inc. is an active patent litigant, engaging in both plaintiff and defendant roles. With two cases as a plaintiff and two as a defendant in our tracked data, its posture aligns with an NPE asserting its acquired and internally developed portfolios against alleged infringers. Many of its plaintiff suits, including recent actions against Infineon Technologies Americas Corp., are filed in plaintiff-friendly venues such as the U.S. District Court for the Western District of Texas.
Recent litigation includes two plaintiff cases against Infineon Technologies Americas Corp. and Infineon Technologies AG, filed in the Western District of Texas and Texas Western District Court in March and April 2025, respectively. Mosaid is also a defendant in a challenge from Unified Patents before the Patent Trial and Appeal Board (PTAB), a common occurrence for NPEs. Another defendant case, brought by Infineon Technologies Americas Corp. et al., is also before the PTAB in August 2025. MOSAID has historically asserted patents covering semiconductor device architecture and fabrication, including FinFET-based manufacturing processes, against major industry players like Intel and Samsung.
