Sable Networks, Inc. (as patent owner) and Sable IP, LLC (as exclusive licensee) have sued Cisco (6:20-cv-00288) in the Western District of Texas, targeting the provision of routers and switches that run on certain platforms and software (e.g., Catalyst Supervisor Engine, Cisco IOS XR, Cisco AVC, etc.). The six patents-in-suit generally relate to network traffic management, with development work done by Caspian Networks (f/k/a Packetcom, LLC), a company formed in 1998 by Lawrence G. Roberts, characterized in the new complaint as one of the “founding fathers of the Internet”.
