Matthew C. Gaudet is the co-chair of Duane Morris' Patent Litigation division. Over the last 20-plus years, he has defeated dozens of patents through trials, summary judgment rulings and IPRs, and he regularly appears before the Federal Circuit. He has served as lead counsel for major technology companies such as Cisco Systems, Verizon, ARRIS, CenturyLink, Seagate, Palo Alto Networks and SonicWall. He has also collected over $100 million for patent holders.
Five years ago, Mr. Gaudet was recognized as one of the top five IP lawyers under 40 in the country by Law360 (in which he was described as a “deadly cross-examiner”). The honor followed a year when two different district courts―one in East Texas, one in Delaware―cited his cross-examinations of opposing experts in rulings that sustained winning jury verdicts, with one judge describing his cross-examination as "brilliant." From 2009 through 2021, Chambers USA: America's Leading Lawyers for Business included Mr. Gaudet in its listing of leading IP lawyers in Georgia. Mr. Gaudet is also listed in Best Lawyers in America and the "Top 100" of Georgia Super Lawyers. Before entering private practice, Mr. Gaudet served a judicial clerkship for the Honorable Susan H. Black of the U.S. Court of Appeals for the Eleventh Circuit. He is a magna cum laude graduate of Duke University School of Law.
