Jason A. Fitzsimmons



Mr. Fitzsimmons is an associate in the Mechanical Group.  He specializes in obtaining patent protection for cutting edge technologies, conducting complex post-grant proceedings at the USPTO, and providing opinions of counsel.

Mr. Fitzsimmons 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: medical devices, sporting goods, physiological sensors, communications systems, consumer electronics, automotive systems, industrial equipment, textiles and apparel, optical devices, image collection and processing, and clean energy technologies.

In the area of post-grant proceedings, Mr. Fitzsimmons has experience in ex parte reexamination, inter partes reexamination, inter partes review, and derivation proceedings.  He is familiar with the challenges faced by both patent owners and third-party requesters in these complex proceedings.  Mr. Fitzsimmons is also 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. This second edition of Patent Office Litigation is the follow up to the first version of the book that was published in 2012 by Thomson Reuters Westlaw, which focused on the contested proceedings that were introduced under the America Invents Act that year.

During law school, Mr. Fitzsimmons 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, Mr. Fitzsimmons 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.
