Centripetal sued Keysight and Ixia in the Eastern District of Virginia. The '213 patent was added by amended complaint on June 13, 2018. The case was litigated through claim construction and trial, but the final damages or settlement figure was not confirmed.
Centripetal accused Cisco of infringement in E.D. Va. After a Zoom bench trial, the district court awarded about $1.9 billion, but the Federal Circuit vacated the judgment and remanded. The '213 claims had been dismissed without prejudice pending IPRs, and on remand Centripetal failed to prove infringement of the retried patents. The docket was administratively closed around July 2025.
Centripetal asserted 13 patents, including the '213 patent, against Palo Alto Networks' NGFW, Cortex, MineMeld, DNS Security, and Panorama products. A jury returned a verdict for Centripetal; the court granted JMOL in part, denied it in part, and denied a new trial. The case was dismissed in part/closed on October 3, 2024.
Case listed in the '213 patent's litigation metadata as an E.D. Va. action filed January 2022; party names and outcome were not confirmed in the narrative.
Cisco petitioned for inter partes review of the '213 patent. The PTAB issued a Final Written Decision finding challenged claims unpatentable; the Federal Circuit vacated that decision and remanded, and the PTAB again found the patent invalid on remand.
