Matthew Moore, one of the nation’s top patent trial attorneys and former Global Chair of the Intellectual Property Litigation Practice and Technology Industry Group, represents leading companies in existential litigation and other high stakes patent disputes.

Recognized as one of the country’s Top 10 Influential Intellectual Property Lawyers, Mr. Moore represents Fortune 100 enterprises and tech-forward companies in their most complex IP litigation matters involving:

  • Patents
  • Trade secrets
  • Antitrust and competition
  • False advertising

He combines extensive trial and appellate experience with his sophisticated technical background to distill complex science and law into actionable advice. Mr. Moore has litigated over 200 cases in venues across the US, including the International Trade Commission (ITC). He has also managed many global patent disputes involving cases around the world, including in Germany, the Netherlands, the UK, Brazil, China, and Japan.

Mr. Moore guides clients across a broad range of sectors, including semiconductors, electrical circuits, telecommunications, medical devices, software, optics, automotive technologies, materials, and chemicals.

He was described by clients and peers to Chambers USA as a “phenomenal trial lawyer who argues many important cases,” “my absolute first choice among all patent litigators,” “all-around excellent,” “a particularly strategic attorney who digs into the facts and has a lot of vision when it comes to litigation strategy,” and “exceptionally bright and gets up to speed on a case quickly. He is a great litigator who is excellent at trial.”

Industry publications often report on Mr. Moore’s litigation prowess, including The American Lawyer, which highlighted the five wins he achieved in one single day and Moore’s “knack for invalidating patents.” The Recorder profiled Mr. Moore for his “patent hat trick” after winning three cases at the Federal Circuit in just one week for Capital One, Freddie Mac, and Volvo. The American Lawyer further praised his IP/antitrust litigation work, noting that his “interesting and aggressive” trial strategy could “reset the playing field on patent litigation.”

Mr. Moore is regularly recognized as a leading intellectual property lawyer by The Legal 500 US, Chambers USA, IAM Patent 1000, Benchmark Litigation, and Managing Intellectual Property.
