Representative Matters

  • Led a trial team through a seven-week bench trial that resulted in the district court invalidating a patent on a $1 billion-per-year drug. The district court’s decision was affirmed on appeal.
  • After a two-week jury trial, achieved a complete victory for his patent owner-client on multiple counts of patent and trademark infringement. The district court subsequently found the infringer in contempt of a post-trial injunction and awarded attorney’s fees for willful infringement. The total judgment was over $12 million on just $2 million in accused sales. In awarding attorney’s fees, the district court noted that the “high level of Plaintiffs’ attorneys’ trial practice skills was a significant factor in achieving a favorable result for the Plaintiffs.”
  • Represented numerous pharmaceutical companies in Hatch-Waxman bench trials concerning myriad drugs and technologies.
  • Represented manufacturer in trade secret misappropriation case against a competitor that hired a former employee. The case was successfully resolved when the defendant agreed to redesign the accused products to remove the misappropriated subject matter.
  • On behalf of an industrial equipment manufacturer, successfully persuaded the Federal Circuit to reverse a decision by the Patent Trial and Appeal Board that the challenged patent was valid.
  • In a case that reached the Supreme Court, represented a worldwide offshore drilling contractor in a patent infringement case involving an offshore drilling apparatus. The case made two trips to the Federal Circuit Court of Appeals and then settled on appeal to the Supreme Court after the Court referred the case to the Solicitor General for review and comment.
