Matthew A. Argenti is a partner in the Palo Alto office of Wilson Sonsini Goodrich & Rosati, where his practice centers on patent litigation with a pronounced emphasis on post-grant proceedings before the U.S. Patent and Trademark Office's Patent Trial and Appeal Board (PTAB). His litigation experience spans a broad array of technologies, including computer networking, anti-virus software, telecommunications, pharmaceuticals, medical devices, and semiconductors. This technical breadth is informed by his pre-law career in the memory products division of Cypress Semiconductor.

The provided case list shows an even split between plaintiff and defendant work, with one appearance on each side. He served as lead counsel for the defendant in Cortex MCP, Inc. v. Visa, Inc., a dispute involving mobile wallet and payment security patents. That case was stayed in the Northern District of California pending the outcome of inter partes review (IPR) proceedings. Argenti also appeared as of counsel for the petitioner in Unified Patents v. Cortex MCP Inc.. Unified Patents is a membership-based organization that often challenges patents asserted by non-practicing entities (NPEs).

Argenti is consistently recognized as one of the most active and effective practitioners before the PTAB, representing both patent owners and petitioners in IPRs and other contested proceedings under the America Invents Act. He has been recognized as a top-performing PTAB attorney by multiple outlets. His practice includes handling subsequent appeals of PTAB and district court decisions to the U.S. Court of Appeals for the Federal Circuit, where he has served as lead counsel.

Mr. Argenti has spent his legal career at Wilson Sonsini. He earned his J.D. with honors from Chicago-Kent College of Law, where he was an editor of the law review, and holds a B.S. in Engineering Physics from Santa Clara University. He is an active member of the State Bar of California.
