Brett Williamson is one of O’Melveny’s most experienced litigators. He leads IP cases for clients in a wide variety of industries, including computer hardware and software, telecommunications and media, electronics, pharmaceuticals, and medical devices. For over 30 years, Brett has helped technology companies solve their most critical legal challenges through a practical approach that prioritizes fundamental “big picture” advice over procedural tactics that can obscure the client’s ultimate business goals, while maintaining the sharp adversarial edge required to ensure winning outcomes.
Brett is routinely recognized among the most skilled IP litigators in the country. He has been named a Top Intellectual Property Lawyer in California multiple times by the Daily Journal, the same publication that listed his trial victory for client Allergan, Inc. as a Top Verdict of 2012. In 2023, Brett was selected as a member of Lawdragon’s inaugural 500 Leading Litigators in America, and he has been described as “a skilled and very practical patent litigator” and a “notable trade secret lawyer” by Legal 500.
Brett is also a longtime member of O’Melveny’s administrative leadership team. He co-founded the firm’s Intellectual Property and Technology practice group, and heads that team in the Newport Beach office. Brett also served a five-year term (2006-2011) as managing partner of the Newport Beach office.
Brett has maintained a robust pro bono practice for more than three decades, most recently securing major victories for clients in the areas of low-income housing and homeless rights, criminal-justice reform, equal protection, and data privacy. He currently serves as O’Melveny’s firmwide partner in charge of pro bono.
