Mesa Digital LLC has filed suit against T-Mobile (1:18-cv-01887) in the District of Delaware over two patents generally related to “multimedia” mobile devices. The complaint calls out T-Mobile’s Coolpad Defiant smartphone; original complaints filed in July against Huawei and ZTE, over the same two patents, make similar identifications (Huawei’s P10 and ZTE’s Axon Elite), but the NPE has since amended the ZTE complaint to swap in AT&T Primetime as the product actually accused of infringement in that case. The patents belong to a family of more than 30, other members of which are held, and have been concurrently asserted by, Mesa Digital affiliate Ortiz & Associates Consulting, LLC. In September, Alphabet (Google) (3:18-cv-05983) filed a Northern District of California complaint seeking declaratory judgments of noninfringement of two of those patents, after Ortiz & Associates voluntarily dismissed an earlier affirmative case in the Northern District of Illinois.
