Seth Lloyd is a partner in the Appellate and Supreme Court practice with particular experience arguing and briefing high stakes patent appeals at the Federal Circuit. Seth is a go-to appellate attorney for complex appeals and has argued many cases in federal and state appellate courts across the country. He is especially skilled in appeals at the intersection of law and technology, where he leverages his strong technical background. Clients appreciate Seth’s ability to distill complicated scientific and legal principles into clear and winning arguments. He takes that approach in the Federal Circuit, where he handles appeals from district courts, the Patent Trial and Appeal Board, and the International Trade Commission. Seth’s winning oral arguments include a successful reversal of three PTAB decisions in a consolidated appeal for a computer memory designer. Seth is also co-chair of the Federal Circuit Bar Association’s Administrative Law & Regulatory Committee. Seth regularly practices in the United States Supreme Court. He has drafted petitions and amicus briefs at the certiorari stage, as well as party and amicus briefs at the merits stage. Seth also moots members of the bar for Supreme Court arguments through the Georgetown Supreme Court Institute and is a barrister in the Edward Coke Appellate Inn of Court. In 2025, Seth won the American Cancer Society Cancer Action Network’s Judicial Advocacy Initiative Award for his pro bono work in support of access to healthcare.Before joining Morrison Foerster, Seth served as a law clerk for Judge Richard G. Taranto of the Federal Circuit. He earned his J.D. from Stanford and holds a Ph.D. in electrical engineering, also from Stanford.
