Philip J. Warrick

Philip J. Warrick is a patent litigation attorney at Irell & Manella LLP, where his practice encompasses intellectual property litigation, appellate matters, and IP policy. He specializes in high-stakes patent disputes, often involving complex technologies. His background includes a Bachelor of Science in Computer Science, which underpins his work in technology-intensive patent areas.

Warrick's practice demonstrates experience representing defendants in patent challenges, as evidenced by his role as counsel for Pictiva Displays International Ltd. in Unified Patents v. Pictiva Displays International Ltd. However, his firm, Irell & Manella, achieved a notable $191.4 million jury verdict for Pictiva Displays International against Samsung Electronics for OLED patent infringement in the Eastern District of Texas, indicating his involvement in representing patent holders as plaintiffs. While one of the patents leading to this verdict was later challenged and canceled by a U.S. patent tribunal, potentially reducing the damages, the case highlights the firm's and his capacity for securing significant outcomes for patent owners.

Before joining Irell & Manella in July 2021 to help launch their Washington, D.C. office, Warrick accumulated 15 years of experience spanning private practice and government service. This includes serving as an associate solicitor for the U.S. Patent and Trademark Office (USPTO), where he argued more than a dozen appeals before the U.S. Court of Appeals for the Federal Circuit. He also acted as IP counsel detailee to U.S. Senator Chris Coons, advising on intellectual property legislation and policy.

Warrick possesses extensive experience with Patent Trial and Appeal Board (PTAB) proceedings, a focus of Irell & Manella's IP practice. He is admitted to the bars of the District of Columbia and New York, among others, including the U.S. Court of Appeals for the Federal Circuit and the U.S. Patent and Trademark Office. He earned his J.D., with high honors, from George Washington University Law School in 2006, and holds a B.S. in Computer Science and a B.A. in Philosophy from the University of Akron, magna cum laude, in 2001.
