O’Melveny’s life sciences team understands the challenges faced by pharmaceutical, medical device, and diagnostics companies, both large and small. It’s a team that understands your science, and understands your business. That’s because our experience goes well beyond law.

Our ranks include former scientists with advanced degrees in chemistry and biology, former life-science industry regulators with the “insider perspective” to deftly steer clients through related governmental inquiries, and boardroom-level counselors with strong ties to the entrepreneurs, scientists, and venture capital firms that drive innovation in the life sciences sector.

Our team has members on the ground in key scientific and commercial centers around the world, including in New York/New Jersey’s pharmaceutical corridor, China’s burgeoning biotechnology market, and in San Francisco, the Silicon Valley, and Newport Beach, servicing California’s northern and southern biotechnology hubs. Immersed in the industry, we have the global reach to support our clients in their efforts to expand and exploit opportunities on a global level, and the familiarity with local players and practices to ensure the success of local and cross-border undertakings.

  • Our life sciences litigators have handled dozens of high-stakes, multi-venued, life sciences litigations, including technically complex patent, Hatch-Waxman, biologics, medical device and other patent litigation, product liability suits and class actions, litigation brought by state Attorneys General, and pivotal labor and trade secret matters. Working side-by-side with our life sciences litigators, our nationally renowned appellate lawyers ensure cases are best positioned on appeal at the onset of litigation.

  • O’Melveny’s white collar lawyers, including many former federal prosecutors, work closely with our life sciences litigators to handle high-stakes government investigations and sensitive internal investigations.

  • Veteran regulatory lawyers—many with former government agency experience—offer critical guidance during investigations and deep insight on compliance issues, both domestic and foreign.

  • Our corporate team provides seasoned, sophisticated counseling on governance matters, strategic transactions, and capital-raising transactions.
