X-Mobile Technologies LLC, an affiliate of monetization firm Empire IP LLC, has initiated a new litigation campaign, asserting up to four former Xybernaut patents in separate Eastern District of Texas cases filed against Amazon (4:17-cv-00703), Apple (4:17-cv-00702), HTC (4:17-cv-00699), Huawei (4:17-cv-00695), Lenovo (4:17-cv-00700), LG Electronics (4:17-cv-00698), Microsoft (4:17-cv-00704), Samsung (4:17-cv-00697), Sony (4:17-cv-00701), and ZTE (4:17-cv-00696). At issue are the defendants’ smartphones, tablet computers, and smartwatches, as well as the Amazon Echo.

Xcelis LLC, an affiliate of Empire IP LLC, has filed suit against Panasonic (2:17-cv-02463), accusing the company of infringement through provision of its Link2Cell phones. The patent-at-issue is generally related to a communications system set up to place either a landline or wireless call. The new case follows on the heels of a dismissal with prejudice in Xcelis’s first case in the campaign, filed against Plantronics in April and ending on September 19.
