Our experience includes:

  • securing a significant victory in the US Supreme Court for Marvel in a dispute over patent royalties for a toy (as a result, Marvel is not required to pay patent royalties to the petitioner, whose patent expired in 2010);
  • securing a complete victory for GoDaddy.com when the US District Court for the Central District of California concluded that GoDaddy acted with a good faith belief that its use of multiple challenged domain names by the plaintiff was a fair use or otherwise lawful;
  • representing Ford Motor Company in a four-patent trial related to collision avoidance and infotainment technology in the Western District of Washington (the jury found in favor of our client and found the plaintiffs and their CEO had misappropriated Ford's trade secrets);
  • securing a US Supreme Court victory for POM Wonderful LLC, which sued a competitor that began selling a “Pomegranate Blueberry” juice product that was 99% apple and grape juice (the Court held that private parties such as POM may bring Lanham Act claims challenging as misleading their competitors' food and beverage labels regardless of whether those labels are regulated by or in compliance with the Food, Drug, and Cosmetic Act);
  • representing Medtronic at the US Supreme Court in a case in which the Court reversed the decision of the US Court of Appeals for the Federal Circuit that the declaratory plaintiff bears the burden of persuasion when a patentee is a declaratory judgment defendant and is foreclosed from asserting an infringement counterclaim due to a license;
  • representing Intel Corporation at the Federal Circuit, which vacated an award of damages by a federal jury in the Eastern District of Texas as well as the district court's ongoing royalty based on that damages award; and 
  • representing GlaxoSmithKline in ANDA litigation filed in the District of Delaware in a case in which the court ruled that the patent at issue—covering the active ingredient in Avodart® and Jalyn™ products—was not invalid, and held that the defendants had not proven by clear and convincing evidence that the asserted claims were invalid for lack of written description, lack of enablement, anticipation or lack of utility.
