  • Mobile Communications and Devices, New Patent Litigation

Proximity Sensors of Texas LLC, an affiliate of monetization firm IP Valuation Partners LLC (d/b/a IPVal), has initiated a new litigation campaign, filing separate suits against Huawei (6:17-cv-00575), Microsoft (6:17-cv-00573), and ZTE (6:17-cv-00574). The patent asserted is generally related to an apparatus on an object’s surface that emits light and receives back reflected light. The new complaints target the defendants’ smartphones that include proximity sensors, used, for example, to turn off the touchscreen when the phone is close enough to a user’s ear. The complaints name Huawei’s Honor 6X, Mate 9, and Nexus 6P phones, together with proximity sensors allegedly provided by AMS, Lite-On Semiconductor, or TXC; various models of Microsoft’s Lumia phones, together with an Avago proximity sensor; and a long list of ZTE phones, together with AMS, Lite-On, or Rohm sensors.
