This past June, CelluPlex LLC opened up a litigation campaign over a single patent generally related to an “interconnect device for coupling a cellular telephone to at least one wired telephone” by filing separate Eastern District of Texas suits against Gigaset Technologies, Mitel Networks, Panasonic, Vtech Holdings, and Yealink Network Technology. So far in September, the New Mexico plaintiff has added a Northern District of Texas complaint against Cornwall Capital Management (Uniden) (3:24-cv-02247), a Northern District of Illinois complaint against Lenovo (Motorola Mobility) (1:24-cv-09091), and additional Eastern District of Texas suits against AT&T (2:24-cv-00789) and Philips (2:24-cv-00790).

CelluPlex LLC has filed separate Eastern District of Texas suits against Gigaset Technologies (2:24-cv-00473), Mitel Networks (2:24-cv-00471), Panasonic (2:24-cv-00474), Vtech Holdings (2:24-cv-00475), and Yealink Network Technology (2:24-cv-00472). A single patent generally related to an “interconnect device for coupling a cellular telephone to at least one wired telephone” is asserted in each complaint, with infringement allegations focused on the provision of telephone systems that support features for connecting to cellular phones via Bluetooth. CelluPlex joins several plaintiffs in forming a curious pattern.
