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.
