Litigation over Former Caspian Networks Patents Expands to Hit Fortinet, Juniper Networks, Palo Alto Networks

Sable Networks, Inc. (as patent owner) and Sable IP, LLC (as exclusive licensee) have added Juniper Networks (6:20-cv-00524) as a Western District of Texas defendant to the campaign that it began in April with a case against Cisco there. The plaintiffs have also sued Fortinet (5:20-cv-00109) and Palo Alto Networks (5:20-cv-00111), this time in the Eastern District of Texas, all of the cases over multiple network traffic management patents, the original development work for which occurred at Caspian Networks (f/k/a Packetcom, LLC), a company formed in 1998 by Lawrence G. Roberts, characterized in the plaintiffs’ complaints as one of the “founding fathers of the Internet”. Various networking devices are the accused products throughout.
