Federal Circuit Vacates Invalidity Finding Regarding Nevro Spinal Cord Therapy Claims

The Federal Circuit recently vacated and remanded a district court’s grant of summary judgment invalidating patent claims owned by Nevro Corporation (Nevro). See Nevro Corp. v. Boston Sci. Corp., Nos. 2018-2220, 2018-2349, 2020 U.S. App. LEXIS 11170 (Fed. Cir. Apr. 9, 2020) (Before Moore, Taranto, and Chen, Circuit Judges) (Opinion for the Court, Moore, Circuit Judge). The district court found the “paresthesia-free” system and device claims to be indefinite because “infringement of these claims depended on the effect of the system on a patient, and not a parameter of the system or device itself.” Using this reasoning, the district court concluded that a skilled artisan could not identify the bounds of the system and device claims with reasonable certainty. The Federal Circuit disagreed.
