He represents clients before federal district courts, the Patent Trial and Appeal Board (PTAB), and the U.S. Court of Appeals for the Federal Circuit.

Jason uses his experience as a district court law clerk and a Federal Circuit law clerk to support clients in formulating winning strategies at each stage of litigation.

Beyond his own trial experience, Jason frequently assists trial teams within and outside of Finnegan as an embedded appellate practitioner and brief writer. He provides valuable guidance in perfecting the record for appeal and handles motions in limine, jury instructions, charge conferences, and mid-trial motions. After trial, Jason manages post-trial briefing and transitions the case to appeal. He has extensive know-how litigating patent damages and Daubert challenges before district courts and the Federal Circuit.
Jason has experience in a wide array of industries, including pharmaceuticals, medical devices, software, mobile phones, semiconductors, process engineering, and consumer products. Jason is a former R&D engineer at a large medical device company, where he designed and tested advanced drug delivery technology and manufacturing processes.
Jason has lectured in the United States and internationally on patent damages, patentable subject matter, and Federal Circuit jurisprudence. He represents parties before the Federal Circuit on a pro bono basis, including parties appealing from the Merit Systems Protection Board (MSPB). Prior to joining Finnegan, Jason served as a judicial law clerk to the Honorable Sharon Prost at the Federal Circuit and to the Honorable Ronald M.
