This past week, Daingean Technologies Limited, an Atlantic IP Services Limited plaintiff, filed its second lawsuit, accusing Deutsche Telekom (Sprint, T-Mobile) (2:23-cv-00347) of infringing the same six patents already in suit against AT&T (AT&T Mobility)—and now Ericsson. Eastern District of Texas Judge Rodney Gilstrap just granted Ericsson’s unopposed motion to intervene in the suit that Daingean filed against AT&T Mobility this past March. Cellular services, particularly via the defendants’ respective 5G networks, are in the crosshairs here.
