Firm overview

Founded less than two years ago, Groombridge, Wu, Baughman & Stone LLP is already widely recognized as one of the nation’s leading patent litigation firms. Our partners have worked together for many years, most recently as the majority of Paul Weiss’s patent litigation group and have a combined 165 years of experience in trials and patent litigation. From small molecules to biologics, from manufacturing to purification to commercial scale-up, and in single-cell sequencing, GPS, medical devices, semiconductors, satellites, and network technologies, we have deep substantive expertise in both the law and in the science. Our lawyers are known for their rapport with juries and judges, for the care and devotion with which they approach their clients, for the scientific expertise they bring, and for their thought leadership in patent law and policy.

The firm’s devotion to clients, commitment to collegiality and diversity, and growing string of victories have propelled it from 21 lawyers at its inception to 32 lawyers today, and from four partners to 10. Founded with offices in New York and Washington, D.C., Groombridge Wu’s success has driven geographic expansion; the firm opened an office in Tokyo’s Marunouchi business hub in December 2023, bringing on long-time Japan-based patent litigator Maxwell (“Mac”) Fox. This firm’s success has not gone unnoticed: it has already been named Benchmark Litigation’s Intellectual Property Law Firm of the Year and shortlisted for that honor by both Chambers USA and Managing IP. Groombridge Wu was also named the 2024 Inter Partes Firm of the Year by LMG Life Sciences and was selected as a Litigation Department of the Year finalist by the New York Law Journal, not to mention dozens of individual recognitions for its partners, such as all partners being named to the Lawdragon List of 500 Leading Litigators of America, and LMG Life Sciences naming Megan Raymond as 2024 Inter Partes Lawyer of the Year.

The firm handles the most significant innovations in the life sciences sector, including, among many others, representing Novo Nordisk in district court and PTAB proceedings involving Ozempic® and Wegovy®, the revolutionary diabetes and weight loss treatments; 10x Genomics in district court and PTAB proceedings concerning 10x’s groundbreaking technology for single-cell DNA and RNA sequencing; Amgen in numerous cases concerning biologic products; Genentech in several high-stakes matters involving its breakthrough cancer and hemophilia treatments; Acuitas in a district court proceeding involving Comirnaty®, Pfizer and BioNTech’s COVID-19 vaccine, for which Acuitas invented the “lipid nanoparticle” that is used to protect and deliver the mRNA; and Fennec in a district court proceeding involving Pedmark® (sodium thiosulfate injection), the only FDA-approved treatment for the prevention of ototoxicity (i.e., deafness) in children with localized, non-metastatic tumors who receive cisplatin chemotherapy. The firm’s expertise spans far beyond the life sciences sector as well, representing, for example, Nearmap in Federal Circuit, district court, and PTAB proceedings involving aerial imagery technology.

The firm also has unsurpassed experience before, and insights into, the PTAB—critical expertise demanded by our marquee technology, biotechnology and pharmaceutical clients. The team includes the country’s preeminent PTAB lawyers, Steve Baughman and Megan Raymond, who have been pioneering trial practice at the PTAB since its first minutes of operation in 2012 and have continuously appeared of record before the PTAB in hundreds of high-stakes proceedings on behalf of both petitioners and patent owners. Our preeminence in intricate, franchise-threatening disputes—typically spanning multiple forums—drives our continued growth. We also have extensive experience in ex parte re-examinations.

Beyond the courtroom, Groombridge Wu partners are leaders in the legal community. Jennifer H. Wu is the president of the Federal Circuit Bar Association (FCBA) president, a position that Nick Groombridge previously held. Jennifer is also a member of the NYU School of Law Board of Trustees, and a member of the board of the Asian American Bar Association of New York (AABANY). Nick and Eric Stone have co-taught Patent Litigation at New York University School of Law. Steve Baughman helped create and is past president of the PTAB Bar Association; Megan Raymond is the association’s current vice-president and is the primary author of PLI’s Post-Grant Proceedings Before the Patent Trial and Appeal Board. Megan also serves on the steering committee of WIN DC (Women in IP Network) and chairs the FCBA’s Patent Litigation Committee. Jennifer Rea Deneault is a junior board member of the New York Intellectual Property Law Association and chairs its membership committee. She is also vice chair of the Patent Litigation Committee for the FCBA. Jenny C. Wu is chair of the Diversity Committee and vice chair of the Mock Argument Committee of the FCBA, and just finished her tenure as the chair of the Litigation Committee of the Asian American Bar Association of New York. Daniel Klein serves as Vice Chair of the Rules Committee and as a member of the Patent Appeals Subcommittee of the FCBA.

Dispute Resolution

A patent-focused intellectual property boutique, with an emphasis on biotech and pharmaceuticals, Groombridge Wu Baughman & Stone got off to a roaring start in 2023 as entity calving off from Paul Weiss with a trial-centric approach and a wave of peer review fueling its market momentum. “This is an IP shop to watch,” advises one peer. “They broke off and took all of their clients with them, and they are steadfastly loyal because [Groombridge Wu] can try cases.” Another elaborates, “They get hired for cases of some enterprise significance. They skew largely in favor of life sciences. There’s a great balance there of Nicholas Groombridge, the polished, eloquent, seasoned statesman, and the group of other name partners (Eric Stone, Steven Baughman and Jennifer Wu), who are younger and really roll up their sleeves and get involved in the trenches.” A client addresses Groombridge as a “great litigator and a consummate gentleman, very professional and great to work with.” Stone is championed for his “Integrity and strategic thinking.” It is also noted that “Groombridge Wu is really growing its younger ranks, although to be fair, it could be said that these people are growing the firm! There is some real brain power there.”
     A firm team, composed of Groombridge, Steve Baughman and Jennifer Wu, is lead counsel for plaintiffs 10x and Stanford University in litigation in the District of Delaware asserting six patents on key technology relating to single-cell sequencing. The team is also lead counsel for 10x in defending the validity of the six patents at the PTAB. The defendant is a competitor to 10x in the single-cell-sequencing market. The team logged wins in three of the six IPRs, convincing the PTAB not to institute. The team also received a unique ruling conditionally terminating two of the instituted IPRs. The firm’s PTAB team, led by Steve Baughman and Megan Raymond, acted for Novo Nordisk, successfully defeating institution of two IPR challenges to patents for the active compound in the blockbuster Ozempic drug in October 2023.
