The practice group at Quinn Emanuel Urquhart & Sullivan, LLP is well-versed in giving oral arguments before the Supreme Court of the United States and a number of state appellate courts alike. The team is routinely engaged on appeals involving copyright, patents, trademark and trade secret law, antitrust, business torts, bankruptcy, and white-collar criminal defense. Key contacts include Washington, D.C.-based Derek Shaffer, who has been engaged by U.S. News in a First Amendment action against the City Attorney of the City of San Francisco; New York-based Sanford Weisburst; and John Bash, who splits his time between Austin and D.C. and has focused his practice on appellate litigation and internal investigations. Ex-practice head Kathleen Sullivan retired in January 2025.
