Jason E. Stach


Jason Stach leads Finnegan’s PTAB trials practice. He practices patent law with an emphasis on post-grant proceedings at the U.S. Patent and Trademark Office (USPTO) and litigation in district courts and at the U.S. International Trade Commission (ITC). He has been lead or back-up counsel in more than 80 Patent Trial and Appeal Board (PTAB) trials, including inter partes reviews (IPRs), covered business method reviews (CBMs), and post-grant reviews (PGRs), and has consulted on dozens of other PTAB trials. Mr. Stach also represents clients before the U.S. Court of Appeals for the Federal Circuit in appeals stemming from PTAB decisions and court actions. In addition to his trial experience, he has taken and defended dozens of depositions, and has argued before the PTAB, at district court claim construction and summary judgment hearings, and at ITC hearings.

In leading the PTAB trials section, Mr. Stach coordinates the firm’s PTAB training programs, workflow, and other aspects of the practice. He also serves as the recruiting partner for Finnegan’s Atlanta office, overseeing the office’s summer associate program and its other recruiting efforts. His pro bono experience includes representing veterans of military service before the U.S. Court of Appeals for Veterans Claims.

Mr. Stach handles cases involving many different technologies, including electrical, computer, software, chemical, pharmaceutical, medical device, and mechanical technologies. Examples include extracting baseband signals from carrier signals in an energy-efficient manner; improving commercial aircraft engines; improving high-speed chip-to-chip signaling techniques using equalization; securing communications over the Internet and other networks; enhancing the control of dynamic random access memory (DRAM) devices; and creating groundbreaking sports sensor technology.
