Atlantic IP’s Croga Innovations Limited has filed suit against Cisco (2:24-cv-00065) in the Eastern District of Texas. Two of the three asserted patents are generally related to isolating a computer environment with a firewall when network communications involve an “untrusted” destination. They share the same source as the two patents already in suit, in a previous case against IBM. Developed elsewhere, the third patent broadly concerns a VoIP system with a “call control gatekeeper”. Cisco is targeted over the provision of the Umbrella remote browser isolation (RBI) tool and the Cisco Unified Broder Element (CUBE) version 14.
