Pegasus Wireless Innovation LLC has filed a second complaint against each of AT&T (AT&T Mobility, Cricket Wireless, New Cingular Wireless PCS) (2:25-cv-00290), Deutsche Telekom (Sprint, T-Mobile) (2:25-cv-00289), and Verizon (TracFone Wireless, Verizon Wireless) (2:25-cv-00288), here targeting the provision of their respective mobile networks and related base stations, as well as the sale of related devices (e.g., smartphones, including those manufactured by Alphabet (Google) or Motorola), that operate in accordance with the 3GPP 4G/LTE and 5G Standards. Both Ericsson and Nokia have intervened in the first round of suits against the US wireless carriers. A claim construction hearing was held there on March 13, 2025, but the litigation to date has otherwise focused on the relationship between Pegasus Wireless and third-party defendant KT, the source of the patents-in-suit.

Pegasus Wireless Innovation LLC has filed its first litigation over patents developed by KT Corporation, suing AT&T (AT&T Mobility, New Cingular Wireless, Cricket Wireless) (2:23-cv-00638), Deutsche Telekom (Sprint, T-Mobile) (2:23-cv-00639), and Verizon (TracFone Wireless, Verizon Wireless) (2:23-cv-00640) in the Eastern District of Texas over 11 of them. The plaintiff pleads that it entered into an “Exclusive License Agreement” with KT but that KT also “transferred to Pegasus all substantial rights in the Asserted Patents”, which Pegasus pleads “were incorporated into and are essential to the 4G/LTE and 5G standards”. The accused products are defined to be “mobile devices identified as supporting 4G/LTE and/or 5G, meaning that they communicate in accordance with, at a minimum, 3GPP Releases 8–15”.
