  • Member of team providing lead counsel representation of Octane Fitness, LLC (Octane Fitness, LLC v. Icon Sports) before the U.S. Supreme Court in its appeal of denial of attorneys’ fees in a patent infringement case. Obtained summary judgment on infringement claims against Octane Fitness and the District Court denied fees. Merits and reply briefs to the U.S. Supreme Court were authored by the team and joined by numerous amici, including the U.S. Solicitor General. In Octane Fitness, LLC v. Icon Fitness and Health, Inc., 134 S.Ct. 1749 (2014), the Supreme Court reversed the Federal Circuit and set a “totality of the circumstances” standard for finding exceptionality to award fees under 35 U.S.C. § 285 to a successful accused infringer. The case garnered significant national media attention and altered the balance of power in patent litigation. On remand, the District Court finally found the original claims against Octane Fitness exceptional and the team secured a fee award of $1.4 million for the client.
