Taylor C. Foss

Taylor C. Foss is an experienced intellectual property litigator at One LLP, with a practice encompassing patents, trademarks, copyrights, trade secrets, and general business litigation. His patent litigation experience spans diverse technologies, including encrypted computer networks, pharmaceuticals, medical devices, and polarized sunglass lenses. Notably, he has handled cases involving biometric liveness detection and 3D face verification software, as evidenced by his role as counsel in FaceTec, Inc. v. Jumio Corporation and FaceTec, Inc. v. Jumio Corporation et al.

Mr. Foss primarily represents plaintiffs in intellectual property disputes. His tracked appearances reflect a focus on the plaintiff side, with all three recorded patent litigation appearances being on behalf of plaintiffs. This preference aligns with his firm's successful representation of clients seeking to enforce their intellectual property rights.

A significant aspect of his practice includes Patent Trial and Appeal Board (PTAB) proceedings. He was involved in the inter partes reviews (IPRs) initiated by Jumio Corporation against FaceTec, Inc., where the PTAB ultimately upheld the patentability of all four challenged claims related to 3D Liveness and biometric identity verification, marking a "total victory" for his client.

Mr. Foss earned his Juris Doctor, cum laude, from American University, Washington College of Law, and a Bachelor of Arts in Political Science from the University of California. He is admitted to the State Bar of California and practices before the U.S. Court of Appeals for the Federal Circuit, the U.S. Court of Appeals for the Ninth Circuit, and the U.S. District Courts for the Central and Northern Districts of California.
