The day after the lapse of a limited term license agreement that ended prior litigation between the two parties, Centripetal Networks has sued Keysight Technologies (2:22-cv-00002) again. Keysight returns to active litigation as an appeal from a large judgment against Cisco proceeds before the Federal Circuit and as March 2021 litigation filed against Palo Alto Networks slogs through discovery, also in the Eastern District of Virginia. Several third-party coalitions have weighed in with respect to the Cisco appeal, primarily to provide competing takes on whether the court’s enhancement of damages as part of that large judgment is consistent with the US Supreme Court’s 2016 Halo Electronics v. Pulse Electronics decision.
