Seth S. Coburn

Seth S. Coburn is a partner in the Intellectual Property Practice Group at Duane Morris LLP, focusing on complex intellectual property litigation across various technologies. His practice spans disputes involving semiconductors, processor architecture, LED lighting, Internet technology, software, telecommunications, consumer electronics, data processing, and GPS-enabled devices. He frequently represents clients in district court litigation, Section 337 investigations before the International Trade Commission (ITC), and post-grant proceedings before the U.S. Patent and Trademark Office (USPTO).

While tracking indicates an appearance on the plaintiff's side in one case, Mr. Coburn's broader practice includes extensive experience defending operating companies against patent trolls and other non-practicing entities (NPEs). He has also represented clients in multi-jurisdictional disputes against primary competitors. Prior to joining Duane Morris in November 2021, he was a partner at Verrill Dana LLP.

A notable engagement includes his representation of Kangxi Communication Technologies (Shanghai) Co., Ltd. in its challenges to patents held by Skyworks Solutions Inc. This included initiating multiple inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB) against Skyworks' patents, alongside parallel district court litigation and an ITC investigation. While some IPR petitions were not instituted procedurally, an Initial Determination by the ITC in Kangxi's favor ultimately led Skyworks to drop all related claims in both the ITC and district court actions. Mr. Coburn regularly handles IPR/PGR proceedings, representing both patent challengers and patent owners, and has secured favorable outcomes.

Mr. Coburn earned his J.D., cum laude, from Boston College Law School in 2011 and a B.A., magna cum laude, from Hamilton College in 2006. He is admitted to practice in Massachusetts and Maine.
