Praised for ‘a deep bench of experienced lawyers and a strong commitment to client service’, the trade secrets practice at Weil, Gotshal & Manges LLP represents both start-ups and publicly traded companies in misappropriation and theft disputes. The team has a track record of successful trials and appeals, but also provides a variety of counseling services and day-to-day advice on the protection of business-critical information. The group has seen several additions in the past year: seasoned tech and life sciences litigators Jeff Homrig and Doug Lumish transferred from Latham & Watkins in July 2025 and now co-lead the group from Dallas and the Bay Area, respectively; Gabriel Gross also joined the Bay area team from Latham in July 2025, noted for his ’excellence in litigation and arbitration’; Boston-based Adam Gershenson onboarded in Oct 2025 from Cooley LLP, noted for his ‘knowledge of the subject matter’; James Pearl joined the Los Angeles office in Sept 2025 from Paul Hastings LLP, adept at handling high monetary damage claims. John Barry co-heads the offering from New York, leveraging employment law expertise. Bambo Obaro is a key contact in the Silicon Valley office, with standout experience in tech litigation.
