Groombridge, Wu, Baughman & Stone

What Groombridge, Wu, Baughman & Stone does

Groombridge, Wu, Baughman & Stone LLP is a U.S. patent litigation boutique founded in November 2022 by six partners — Nicholas Groombridge, Jennifer H. Wu, J. Steven Baughman, Eric Alan Stone, Megan F. Raymond, and Josephine Young — all previously recognized as leading IP trial practitioners. The firm maintains offices in New York (headquarters), Washington DC, and Tokyo (opened September 2023 under Maxwell "Mac" Fox, a U.S. IP litigator and Japanese-licensed Gaikokuho Jimu Bengoshi), giving it a trilateral footprint aligned to the principal U.S. patent litigation venues (district courts, the PTAB, the ITC, and the Federal Circuit) plus cross-border matters involving Japanese clients.

The firm practices exclusively in intellectual property litigation across six practice areas: District Court Litigation and Arbitrations, Federal Circuit Appeals, Patent Trial and Appeal Board (PTAB) proceedings, ITC Investigations, Trade Secret Litigation, and Pro Bono and Public Service. Its matters span Hatch-Waxman pharmaceutical patent challenges, biologics and life sciences disputes, medical device and semiconductor patent cases, and technology/SEP matters. Representative clients include Amgen, Genentech, Novo Nordisk, Google, Cisco, Garmin, and Edwards Lifesciences — an exclusively enterprise, Fortune 500-class client base. Individual partner credentials include Chambers Band 1 IP: Patent rankings (Groombridge), a 47-0 PTAB final written decision record (Baughman), and bar leadership roles such as past President of the Federal Circuit Bar Association (Wu) and current President of the PTAB Bar Association (Raymond).

The firm operates on a traditional professional services / billable hour revenue model. Disclosed compensation bands suggest Patent Litigation Associate salaries of $250K-$385K and Legal Administrative Assistant salaries of $75K-$95K, consistent with AmLaw/leading-boutique billing rates. GTM is partner-led, with no external equity, private equity, or venture capital ownership; the firm has pursued an aggressive buildout of talent, brand (Benchmark Litigation 2024 IP Firm of the Year, Chambers USA 2024 shortlist), and infrastructure (a 10-year, 43,000-square-foot Manhattan lease signed in February 2026).
