Weil, Gotshal & Manges
Firm overview:
With a formidable reputation for resolving the most complex and high-stakes disputes, Weil, Gotshal & Manges stands out as a powerhouse in trade secrets litigation and advisory work. The firm blends deep technical fluency with sharp courtroom advocacy, guiding global clients through the full spectrum of trade secrets matters—from preventative strategies and internal investigations to bet-the-company litigation and cross-border enforcement.
The trade secrets team’s collaborative approach draws on Weil’s broader litigation and transactional strengths, ensuring seamless handling of matters involving concurrent antitrust, contract, and employment law dimensions.
Team overview:
In what will undoubtedly be seen as a major coup, Weil boosted its litigation capabilities in August 2025 with the addition of a trio of partners from Latham & Watkins who specialise in technology and life sciences IP matters and have significant trade secrets expertise.
Douglas (Doug) Lumish and Jeff Homrig returned to the firm as co-heads of the IP, Technology & Science Litigation practice, having previously spent more than a decade at Weil as part of its patent and IP litigation team.
Lumish, based in Silicon Valley, has represented some of the world’s leading technology and life sciences companies on their most important IP and technology-related litigation, including acting as lead trial counsel on trade secrets cases for Amazon and Meta. A peer comments on his stand-out “style and practice”, explaining that Lumish has “an intuitive understanding of how to present information in a way that’s digestible”, noting that “it’s almost like he’s having a conversation with the judge”.
Trial lawyer Homrig has handled mission-critical patent, trade secrets, and commercial cases across the US, and brings over 25 years’ experience in such matters to Weil. He has counselled clients through trade secrets cases involving email security, renewable fuels, drone technology and more, and was previously global vice chair of Latham’s IP litigation practice.
Also joining Weil from Latham, Gabe Gross leads cases for life sciences and technology companies, focusing on disputes involving patents, trade secrets, licences, contracts and other IP issues. A skilled courtroom advocate, Gabe has won jury verdicts, summary judgments, arbitration awards and appeals on behalf of clients ranging from Fortune 500 tech companies to innovative startups.
Shortly after news of the trio’s move was made public, it was announced that IP litigators Chris Henry and Gaby LaHatte had also left Latham for Weil. Both Henry and LaHatte have trade secrets expertise, having handled high-stakes matters for clients in a multitude of life sciences and technology fields.
The new additions to the team join trade secrets experts such as John Barry, who heads the Employment Practice Group, and Bambo Obaro, co-managing partner of the Silicon Valley office who focuses much of his practice on employee mobility and trade secrets-related issues.
