Highlights:

  • On the strength of Cliff’s strategy, Sony won summary judgment of noninfringement, protecting Sony from the plaintiff’s request for nearly $500 million in damages.
  • Cliff was a member of the trial team that secured a unanimous jury verdict of noninfringement for Garmin, whose most popular smartwatches had been accused of infringement.
  • Cliff and the Erise team successfully defended FanDuel from a claim that it was infringing 10 patents by successfully whittling the 10 patents down to a single dependent claim of a single patent, before invalidating that remaining claim under 35 USC § 101. When the Plaintiff appealed, Cliff was a member of the appeal team and was responsible for FanDuel’s briefing. Cliff and the appeal team successfully secured a Rule 36 affirmance from the Federal Circuit.
