Jason E. Stach


Jason Stach leads Finnegan's PTAB trial 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). With experience in more than 80 inter partes review (IPR) proceedings, Mr. Stach represents clients before the Patent Trial and Appeal Board (PTAB) and in inter partes and ex parte reexaminations. He also represents clients in Federal Circuit appeals stemming from reexaminations and court actions.

Mr. Stach has been to trial multiple times; argued at claim construction, summary judgment, and other hearings; cross-examined and defended dozens of witnesses at deposition or trial; and served as lead counsel in a number of proceedings. He frequently writes and speaks on PTAB and litigation issues.

Mr. Stach provides patent prosecution and client counseling services. He concentrates primarily in the areas of electrical, computer, and software technologies, but has been also involved in matters addressing chemical, pharmaceutical, and mechanical issues. Technologies involved in recent cases include extracting baseband signals from carrier signals in an energy-efficient manner, 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 sports sensor technology.

His pro bono experience includes representing veterans of military service before the U.S. Court of Appeals for Veterans Claims. He serves as the hiring partner for Finnegan's Atlanta office.
