Reed Semiconductor Corp.

Reed Semiconductor Corp., commonly known as Reed Semiconductor, is a private fabless semiconductor company founded in 2019 and headquartered in Warwick, Rhode Island, USA. The company also maintains offices in Taipei, Shenzhen, and Bangalore. With a team size reported to be around 57 to 200 employees, Reed Semiconductor has raised $11.5 million in funding, with UMC Capital listed as an investor.

Reed Semiconductor specializes in power management integrated circuits (PMICs) for various applications. Their product portfolio includes multiphase controllers, smart power stages, Point-of-Load (POL) DC-DC converters, intermediate bus converters (IBC), eFuses, and power muxes. These solutions are designed for high-performance computing in data centers, AI accelerators, graphics cards, as well as automotive, industrial, and telecommunications systems.

Reed Semiconductor demonstrates an active two-way litigation posture, appearing as both a plaintiff and a defendant in tracked patent cases. The company is currently involved in two tracked cases. In October 2025, Reed Semiconductor Corp. filed a patent infringement lawsuit against Monolithic Power Systems, Inc. in the U.S. District Court for the Western District of Texas, a venue often favored by plaintiffs, alleging infringement of U.S. Patent No. 7,960,955. This action followed earlier lawsuits initiated by Monolithic Power Systems against Reed.

In a related context, Reed Semiconductor was a defendant in a Patent Trial and Appeal Board (PTAB) proceeding initiated by Monolithic Power Systems. In January 2026, Reed Semiconductor prevailed in this PTAB challenge, with the board finding U.S. Patent No. 9,041,377 B2, owned by Monolithic Power Systems, unpatentable. Furthermore, in April 2026, the USPTO denied a separate validity challenge by Monolithic Power Systems against Reed's own U.S. Patent No. 7,960,955, the patent currently being asserted in the Western District of Texas case.
