Alphabet (Google) (3:23-cv-03624) has filed an action in the Northern District of California against AGIS Holdings Inc. and its subsidiaries Advanced Ground Information Systems, Inc. (AGIS) and AGIS Software Development LLC (ASD), seeking declaratory judgments of invalidity, noninfringement, and unenforceability of a single patent generally related to a “forced message alert software application program” which requires participants to respond after receiving an alert. Google alleges that AGIS Holdings—through its two controlled plaintiffs—has asserted the patent against its Find My Device application in multiple cases, two against Google itself as well as several against others (e.g., HTC, Huawei, LG Electronics (LGE), and ZTE).
