Pearl IP Licensing LLC, an entity apparently associated with Texas monetization firm IP Edge LLC, has sued Deutsche Telekom (T-Mobile) (6:20-cv-00260) over a single patent generally related to a circuit that can recover from certain “stress conditions”. T-Mobile is accused of infringement through the provision of certain “apparatus[es]”—identifying as an exemplary accused product the Motorola Z2 Force smartphone, targeted over its inclusion of Qualcomm processors with certain power and voltage management features. Pearl IP asserts current ownership of the former Cypress Semiconductor patent, which publicly available USPTO records indicate was received by IP Edge as part of a larger assignment from another NPE.
