NetSocket, Inc. has launched its first litigation, filing an Eastern District of Texas complaint that accuses Cisco (2:22-cv-00172) of infringing two patents through the provision of networking products with certain quality of service (QoS) features. The plaintiff, once a provider of cloud-managed virtual network services according to its now-defunct website (archived here), appears to have pivoted to patent assertion with the help of a funder linked to several other litigating NPEs.
