Experience :

  • Represented the United States defense industry and filed an amicus brief in a complex and critical appeal before the Court of Appeals for the Federal Circuit involving government contractor immunity under 28 U.S.C. § 1498 for patent infringement. The court went en banc to adopt the client’s position that contractor immunity should apply, and overturned recent precedent to the contrary.
  • Defended the United States at both the trial and appellate levels against a massive $3 billion patent infringement claim involving over 100 satellites (including GPS satellites) and thousands of government contracts. The case was one of the largest patent infringement actions in history, resulting in more than 20 published Court of Federal Claims, Federal Circuit and Supreme Court decisions.
  • Representing a technology company as lead attorney in enforcing its patent portfolio on advanced “smart” power cord technology against competitors. The enforcement effort has encompassed several successful district court litigations and resulted in multiple royalty-bearing licenses.
  • Represented clients in numerous matters involving nonpracticing entities (NPEs) in the Eastern District of Texas and other district courts. Presented arguments as lead attorney at numerous Markman (claim construction) hearings and represented clients in several cases in which claims against the client were dismissed without payment.
