We are an IP Litigation powerhouse for technology, life sciences and health technology in patents, trade secrets and commercial litigation with unparalleled trial success at all levels at each forum and venue. Our approach integrates our practices to provide businesses with comprehensive intellectual property protections. Our litigation expertise and experience also gives us an edge in advising our clients on the likely outcomes of litigation, including in the context of corporate acquisitions and portfolio management. Our approach, which supports “small firm” key partner attention with the “large firm” resources ensures our clients receive effective and efficient representation at every stage of the case. We are committed to helping clients structure the most comprehensive and workable enforcement and defense for all aspects of their intellectual property. 


Bench and Jury Trials at the U.S. District Courts

  • We have litigated and counseled on patent and trade secrets issues across a wide range of industries, including software, hardware, electronics, chemical processes, telecommunications, consumer goods, manufacturing, sales, financial services, and pharmaceuticals.
  • We are also experts in §101 invalidity challenges with a near-perfect record in district court and the Federal Circuit, pursuing and obtaining attorneys’ fees, and obtaining wins in Federal Circuit appeals.
  • We are experts in the nuances of life sciences patent litigation, including Hatch-Waxman Act and biosimilars patent litigation under the Biologics Price Competition and Innovation Act, and the intersecting FDA regulatory regime in which these cases operate. 


PTAB Proceedings

  • We have handled over 400 post-grant proceedings before the U.S. Patent Trial and Appeal Board, on behalf of both petitioners and patent owners across a wide range of industries.
  • Our attorneys have been hailed as ones who can be “trust[ed] . . . with crown jewels, and have been described as “PTAB mastermind[s],” “PTAB trial guru[s],” knowing the PTAB “like the back of [their] hands,” and “understand[ing] all the rules and subtleties of IPR proceedings better than anyone I’ve ever worked with.”
  • Our attorneys worked on the first ever PTAB proceeding on the technology side and also led the first ever successful defense of a pharmaceutical patent.


ITC Section 337 Investigations

  • We represent both complainants and respondents, and have been at the forefront of recent cutting-edge decisions at the ITC. 
  • We have served as counsel in more than 60 Section 337 Investigations, and have appeared before each of the Presiding Administrative Law Judges (ALJs), including multiple successes before Customs in ensuring our clients’ products are not excluded from the United States. 


International Arbitrations

  • We represent clients in all aspects of litigation related to arbitration, including bringing and defending motions to compel arbitration, obtaining and opposing interim and protective measures in aid of arbitration, seeking and opposing recognition of arbitral awards, seeking and opposing the annulment of arbitral awards, and disputes over the taking of evidence in the US in aid of international arbitrations and foreign litigation.
  • We regularly draft, advise, and teach courses on the drafting and interpretation of arbitration and forum-selection agreements in circumstances ranging from simple two-party deals to complex commercial transactions involving multiple parties, jurisdictions, and applicable laws. We recognize that each matter is unique and strive to meet our client’s objectives in the most cost-effective manner.


Supreme Court and Appellate Review

  • We have top-notch appellate capabilities and can handle an IP litigation matter from start to finish. 
  • Our lawyers are skilled in the art of written and oral advocacy, as well as in simplifying technical arguments for generalist Federal Circuit judges.
  • We devote our practice to the craft of conceiving and presenting argument on complex, law-intensive issues, bringing to bear our many years of experience in areas of law that cut across traditional legal disciplines, such as constitutional interpretation, damages, procedure, and jurisdiction.
