Proximity Sensors of Texas LLC, an affiliate of monetization firm IP Valuation Partners LLC (d/b/a IPVal), has filed new cases in its campaign over a single patent generally related to an apparatus on an object’s surface that emits light and receives back reflected light. The NPE accuses AMS (AMS-TAOS USA) (4:19-cv-00026) in the Eastern District of Texas and ROHM (ROHM Semiconductor USA) (1:19-cv-00208) in the Northern District of Illinois of direct infringement, calling out their AMS tmd2771/ tmd277x and ROHM rpr0521 sensors, respectively, further alleging indirect infringement through the provision of products (e.g., smartphones and tablets) that include such sensors. In prior cases in the campaign, Proximity Sensors named smartphone and tablet makers themselves—Apple, Huawei, Microsoft, and ZTE—as defendants.
