Samsung (2:24-cv-01051) is the latest defendant to be added to the sole litigation campaign of Nodal Technologies LLC, launched in May 2022 with a suit against Deutsche Telekom (T-Mobile). In the new Eastern District of Texas complaint, the plaintiff asserts a single patent generally related to a certain “mobile communications station” in a network that is organized into “clusters”; Samsung is accused of infringement through the provision of base stations, including the CDU50 Next Generation Baseband Unit, that support certain cellular networking technologies (i.e., LTE (eNB) and NR (gNB)).

The initial case filed by Nodal Technologies LLC, against Deutsche Telekom (T-Mobile), saw first Ericsson and then Nokia intervene, before the claims against each of the three defendants were dismissed with prejudice in light of successive settlements, with Ericsson then Nokia then T-Mobile. Only one of the two patents asserted there is now in suit again, this time against AT&T (AT&T Mobility) (2:23-cv-00432), accused of infringement “by using its LTE v.10-compliant and 5-G compliant wireless telecommunications networks”.
