Jason Clarence Williams

Jason C. Williams is a patent trial lawyer at Quinn Emanuel Urquhart & Sullivan, LLP, based in their New York office. While the firm's tracked cases show his appearances exclusively on the defendant side, his professional biography indicates extensive experience serving as trial counsel for both plaintiffs and respondents in patent infringement actions and International Trade Commission (ITC) investigations. He has been recognized as Of Counsel at Quinn Emanuel since January 2025.

Mr. Williams' practice focuses on high-technology disputes, encompassing a broad range of technologies. His expertise includes wireless communications (5G and Wi-Fi 7 telecommunications), semiconductors (microprocessors, integrated circuits, Bluetooth), consumer electronics (action cameras, optical disc drives, LED lighting systems), and software (anti-piracy software, instant messaging). He handles disputes involving utility and design patents, trademarks, trade secrets, and standard-essential patents (SEPs).

His notable experience includes significant Section 337 investigations before the U.S. International Trade Commission. He served as trial counsel for Complainant Juul Labs, Inc. in an investigation concerning vaporizer devices and cartridges, securing an initial determination of violation on four asserted patents, which the Commission affirmed, issuing a limited exclusion order. He also represented Complainant GoPro, Inc. in an ITC investigation against Arashi Vision Inc. (Insta360) regarding action camera technology, where infringement was found for one patent, leading to a limited exclusion order and a cease-and-desist order. Mr. Williams has tried patent cases to verdict in U.S. district courts in leading venues such as the Eastern District of Texas, the District of Delaware, the Northern District of California, and the District of Massachusetts.

Mr. Williams earned his J.D. from William & Mary School of Law in 2013 and holds an electrical engineering degree from Rensselaer Polytechnic Institute (2007). He is admitted to practice in Massachusetts and before the U.S. Court of Appeals for the Federal Circuit and the First Circuit.
