In January, Vision Sphere Labs LLC expanded its sole litigation campaign with suits against FS.com (2:25-cv-00075) and Perle Systems (2:25-cv-00079) in the Eastern District of Texas. The two asserted patents—each originating with Harris Corporation (which merged with L3 Technologies to become L3Harris in 2019)—are broadly directed to network Quality of Service (QoS) technologies. The defendants are accused of infringement over the support of certain QoS technologies in their respective routers, switches, and platforms.
