Inventor-controlled 511 Innovations, Inc. kicked off its first litigation campaign with three suits against a group of device makers and semiconductor companies. Each of the complaints asserts a different combination of a group of eight patents, all of which generally concern optical measurement (6,307,629; 6,490,038; 6,915,955; 7,110,096; 7,113,283; 7,397,541; 8,472,012; 8,786,844). The defendants are grouped as follows: HTC with Vishay Intertechnology (2:15-cv-01524), Huawei, Samsung, and ZTE with AMS (2:15-cv-01526), and Microsoft with Avago (2:15-cv-01525). 511 accuses the device makers’ mobile phones, and the semiconductor defendants’ light sensors incorporated in those phones, of infringement.
