Addressing the proper test for shifting fees under 35 U.S.C. § 285, the US Court of Appeals for the Federal Circuit held that a district court erred when it shifted fees to the accused infringer because the district court found that only a series of events was exceptional but did not determine that the “case ” was exceptional. Intellectual Ventures LLC v. Trend Micro Inc., Case No. 19-1122 (Fed. Cir. Dec. 19, 2019) (Stoll, J.). Because it was unclear what standard the district court used when making its “exceptional case” determination, the Federal Circuit vacated and remanded for an analysis under the proper legal standard.
