With a wealth of trial successes across numerous practices and industries, David's deep experience further bolsters Latham's reputation as an unmatched antitrust and litigation powerhouse.

NEW YORK, Aug. 1, 2025 /PRNewswire/ -- Latham & Watkins LLP¹ is pleased to announce that David Marriott, one of the most prominent and successful trial lawyers in the country, has joined the firm's New York office as a partner in the Antitrust & Competition Practice and a member of the Litigation & Trial Department. Focused on guiding multinational companies through their most high-stakes disputes, Marriott regularly handles precedent-setting antitrust litigation, and brings significant experience in intellectual property, complex commercial, and securities litigation matters.

Widely recognized as among the country's standout trial attorneys, Marriott handles bet-the-company cases and has tried disputes in both federal and state courts across the US and successfully handled appeals across numerous high-growth industries, including media and entertainment, technology, healthcare and biotech, telecoms, consumer goods, heavy industry, and transportation.

"We're immensely proud of our firm's ability to achieve transformational successes for our clients," said Rich Trobman, Chair and Managing Partner of Latham & Watkins. "The addition of Dave, a formidable talent and leading trial lawyer known for winning the hardest cases, makes perfect sense as we focus on delivering sophisticated legal advice that enables our clients to see around corners, beat down challenges to achieving their business goals, and further hone their competitive position."

"In addition to being a critical hub for our world-class transactional practice, New York is also a key center for litigation, and Dave is at the top of the bar," added Marc Jaffe, Managing Partner of the firm's New York office. "With a tremendous track record handling complex disputes and a reputation for excellence, Dave is a superb addition to our market-leading New York litigation team and an invaluable asset for our clients."

"In just four months, Latham has added the top antitrust litigators on each side of the Atlantic, Dave and Alfonso LaMadrid, to our already elite global antitrust practice," said Mike Egge, Global Chair of the firm's Antitrust & Competition Practice. "Clients today want the complete package in antitrust — a team that can clear their biggest strategic deals anywhere in the world, combined with best-in-class litigators to defeat any possible challenges to those deals and to defend their everyday business conduct. Dave is a proven winner in court, and his joining our team makes every part of our offering more compelling. We have known and admired Dave for years, having worked alongside him on two antitrust merger trial wins over the last four years, and we are absolutely thrilled to call him our partner."

"I am fortunate to have had the opportunity to practice alongside and across from Latham multiple times over my career, and I couldn't be more excited to become part of this exceptional team," stated Marriott. "It wasn't just the firm's renowned global platform and its position as the go-to elite antitrust team that attracted me. Latham's collaborative culture, and the firm's ability to seamlessly provide comprehensive legal solutions to companies around the world, make for the perfect pairing to help drive my practice forward, particularly as litigation challenges grow more complex and multi-faceted."

Marriott is a fellow of the prestigious American College of Trial Lawyers and the International Academy of Trial Lawyers. He teaches antitrust, intellectual property, and trial practice as an adjunct professor at New York University School of Law and lecturer at Columbia University School of Law.

Marriott joins from Cravath, Swaine & Moore. He received his JD from New York University School of Law in 1994 and his BA magna cum laude from Brigham Young University in 1991.
