Another apparent affiliate of monetization firm IP Edge LLC has expanded an existing litigation campaign. Last month saw dismissals in earlier Techno Licensing LLC cases, against Airbus, Telus, and Verizon, as well as a new suit filed against Telapex (Cellular South); so far this month, the NPE has sued Dillon Kane Group (1:18-cv-06505), NEC (3:18-cv-02559), Simoco EMEA (2:18-cv-00405), and Zebra Technologies (1:18-cv-06506) in various districts. Throughout this campaign, Techno Licensing has asserted a single patent generally related to push-to-talk (PTT) over cellular (PoC) service, with infringement allegations targeting devices that support PoC communications.
