Joshua C. Harrison is a partner at the intellectual property boutique Barceló, Harrison & Walker, LLP, where his practice encompasses patent litigation, patent prosecution, and post-grant proceedings. His litigation work is informed by his technical background in mechanical and electrical engineering, with experience in diverse fields such as information storage devices, sporting equipment, medical devices, and firearms technology. Dr. Harrison's career includes prior experience as a litigation associate at Irell & Manella and as an in-house patent attorney at Western Digital Corp.

Based on the tracked case list, Dr. Harrison's work has involved representing large operating companies. In the multifaceted dispute between Valve Corporation and Ironburg Inventions Ltd., he represented Valve. While the provided data lists this as a plaintiff-side appearance, public records clarify that his client Valve was the defendant in the district court infringement suit brought by Ironburg but was the petitioner (the challenging party) in related inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB). This prominent litigation involved a jury verdict of willful infringement, an award of over $4 million in damages against his client, and multiple subsequent appeals to the U.S. Court of Appeals for the Federal Circuit.

Dr. Harrison has significant experience in post-grant proceedings before the PTAB, a focus highlighted by his firm. His role as counsel for petitioner Valve in the IPRs against Ironburg's patents underscores this expertise. In addition to his work as an attorney, he also serves as a technical expert witness in patent litigation matters.

He earned his J.D. from Stanford Law School and holds a Ph.D. in Mechanical Engineering from the University of California, San Diego, as well as a B.S. in Mechanical Engineering from the University of Southern California. He is a member of the State Bar of California.
