Gregory P. Durbin

Gregory P. Durbin is an Of Counsel attorney at Polsinelli, where he also serves as Co-Chair for Electrical Engineering & Computer Science Patent Prosecution. His patent litigation practice is characterized by a strong technical background as a former electrical engineer, which he leverages to develop intellectual property strategies for innovators, early-stage companies, and investors.

Durbin's practice spans a wide array of technology areas, including battery technology, conventional and green energy technology, artificial intelligence, vehicle systems, computer hardware, telecommunications, enterprise software, data center products and services, high-voltage electronics, and graphical user interfaces. He typically advises clients on patent portfolio development and management, design-around efforts, due diligence, and freedom-to-operate assessments. In litigation, he collaborates with trial teams on overall strategy, key technical and legal positions, claim construction, dispositive motions, expert reports, and settlement negotiations.

He primarily represents defendants in patent litigation, with a notable appearance as Of Counsel for Ford Motor Company in Ford Motor Company v. Massachusetts Institute of Technology et al. This case involved patents related to fuel management systems for internal combustion engines. While other counsel were specifically credited for the wins, related inter partes review (IPR) proceedings involving these patents resulted in the invalidation of three Massachusetts Institute of Technology (MIT) patents at the Patent Trial and Appeal Board (PTAB), a decision subsequently affirmed by the Federal Circuit in December 2025. His firm, Polsinelli, is recognized for its capabilities in post-grant proceedings, and Durbin's Chambers profile also lists "Post Grant Proceedings" as a practice area.

Durbin holds a J.D. and a Master of Intellectual Property from Franklin Pierce Law Center (1999) and a B.S. from the University of Michigan (1991). He is admitted to the Colorado Bar, registered to practice before the United States Patent and Trademark Office, and admitted to the U.S. Court of Appeals for the Federal Circuit, the U.S. District Court for the District of Colorado, and the U.S. District Court for the District of Minnesota.
