New NPE Tags Second Wireless Carrier over Provision of Its 3G Network

  • June 21, 2019
  • Mobile Communications and Devices, Networking, New Patent Litigation

A week after hitting AT&T (AT&T MobilityCricket Wireless) over the same five patents, recently formed Delaware entity Cellular Evolution LLC has followed up with a similar case filed against T-Mobile (2:19-cv-00232), also in the Eastern District of Texas. The wireless communications patents form a single family originating with failed Korean mobile phone maker Pantech, Cellular Evolution alleging that each has been declared essential to the UMTS RRC Protocol (as identified in the ETSI Special Report SR 000 314). The NPE’s complaints target the two wireless providers’ respective 3G networks, with the T-Mobile complaint calling out its alleged sale of “products for use on its network”, including certain mobile devices made by Alphabet (Google), Apple, Lenovo (Motorola Mobility), LG Electronics, OnePlus, Samsung, TCL (under the Alcatel brand), and YuLong Computer Telecommunication (Coolpad).
