CAFC Vacates Non-Infringement Ruling for Apple Due to District Court Error in Striking Expert Opinion

The U.S. Court of Appeals for the Federal Circuit (CAFC) on Wednesday vacated a district court’s grant of summary judgment of non-infringement for Apple, holding that the district court abused its discretion in striking an expert infringement opinion.

On Wednesday, the U.S. Court of Appeals for the Federal Circuit issued a split ruling in Acufloor, LLC v. EvenTile, Inc. vacating a stipulated judgment of non-infringement by the Middle District of Florida following claim construction in infringement litigation between rivals in the ceramic tile installation industry. Although Judge Leonard Stark concurred with the panel’s vacatur, he dissented from the majority’s narrow construction of the claim term “edge,” arguing that the proper course of action for the appellate court was to remand to the district court under Acufloor’s proposed broader construction, which creates enablement issues that the district court should address in the first instance.
