Graham M. Buccigross is a Partner in the Intellectual Property practice at Mayer Brown, based in their Northern California offices (Palo Alto & San Francisco). With two decades of experience, he focuses on litigating intellectual property and high-technology contractual disputes.

Buccigross's practice heavily emphasizes high technology, particularly in telecommunications, including standards-essential patents (SEPs), semiconductors, light-emitting diodes (LEDs), and computer hardware and software. His background includes training in both engineering and life sciences, allowing him to handle a diverse array of patented technologies. He has represented clients in district court litigations, before the US International Trade Commission, and the US Patent and Trademark Office.

In terms of case involvement, Buccigross has primarily worked on the plaintiff side in tracked patent litigation, appearing as counsel in two plaintiff-side cases and one defendant-side case. Notably, he was part of the Mayer Brown trial team that secured a significant victory for Pantech Corporation and Pantech Wireless, LLC against OnePlus Technology (Shenzhen) Co., Ltd. in the Eastern District of Texas. In this March 2024 case, a jury found that OnePlus willfully infringed five of Pantech's patents related to wireless communication and user interface technologies and awarded substantial damages. Buccigross also represented Pantech in related global licensing and enforcement efforts for its telecommunications patent portfolio, which includes SEPs. He has experience representing clients in arbitrations related to intellectual property licenses and technology usage, with favorable outcomes in cases involving microprocessor technology and LED patent cross-licenses. Buccigross is also involved in Federal Circuit appeals stemming from the Pantech v. OnePlus litigation. His PTAB experience includes acting as counsel for Pantech in IPR proceedings, such as OnePlus Technology (Shenzhen) Co., Ltd. v. Pantech Corporation (IPR2025-00783), where a request for discretionary denial by Pantech was addressed.

He earned his B.S., summa cum laude, from the University of California, San Diego, and his J.D., cum laude, from Harvard Law School.
