Vision Sphere Labs LLC has added two Western District of Texas suits—one against each of Lantronix (1:25-cv-00334) and Rubicon Communications (1:25-cv-00332)—to the campaign that it started last fall with separate Eastern District of Texas cases against Grandstream Networks and Firewalla and expanded earlier this year against Perle Systems and FS.com in the same district. Targeted throughout has been the provision of routers, switches, and platforms that support certain QoS (“Quality of Service”) features.
