Jason A. Fitzsimmons is an associate in Sterne Kessler’s Mechanical & Design Practice Group. Jason specializes in obtaining patent protection for cutting edge technologies, conducting complex post-grant proceedings at the USPTO, and providing opinions of counsel.
Jason has broad experience in preparation and prosecution of U.S. and foreign patent applications and in research and preparation of validity, infringement, and patentability opinions. His primary areas of technical experience include: sporting goods, medical devices, physiological sensors, communications systems, consumer electronics, automotive systems, industrial equipment, textiles and apparel, optical devices, image collection and processing, and clean energy technologies.
A major focus of Jason’s practice is post-grant proceedings. He has significant experience in inter partes reviews (IPRs), as well as ex parte reexamination, inter partes reexamination, and derivation proceedings. He is familiar with the challenges faced by both patent owners and petitioners in these complex proceedings. Jason is a contributing author of Patent Office Litigation, Second Edition, published in 2017. The book provides a fresh and comprehensive exploration of patent office litigation proceedings, including how the proceedings interact with other aspects of patent procurement and enforcement, while delivering practical analysis and advice.
During his time at The George Washington University Law School, Jason served as the student editor-in-chief of the American Intellectual Property Law Association Quarterly Journal. He was also a member of the Moot Court Board Executive Committee and vice president of the Student Intellectual Property Law Association (SIPLA).
Prior to law school, Jason gained industry experience as an engineer for a defense contractor. He managed a project to develop innovative, lightweight armor solutions for combat vehicles and oversaw ballistic testing. Additionally, he worked on a project to design a system for remote detection of nuclear materials by overcoming natural phenomena such as particle scattering and temporal detection delays.
Jason earned his B.S. in physics-engineering, magna cum laude, from Washington & Lee University.
