The Verdict & Legal Analysis
Outcome
The Federal Circuit issued a decisive ruling: the denial of JMOL of noninfringement was reversed, and the damages award was vacated in its entirety. The specific damages amount from the underlying trial was not publicly disclosed in the appellate record provided, but its full vacatur reflects the comprehensive nature of the reversal. No injunctive relief analysis was reached given the infringement reversal.
Key Legal Issues
The core legal question before the Federal Circuit was whether the district court erred in denying JMOL of noninfringement — meaning whether Finesse Wireless had presented legally sufficient evidence at trial to support a jury finding of infringement. The Federal Circuit concluded it had not. By reversing the JMOL denial, the court found that the evidence presented at trial was legally insufficient to sustain the jury’s infringement verdict as a matter of law. This type of reversal typically hinges on claim construction or on a failure of proof that the accused products satisfy each claim limitation.
