Twitter (5:21-cv-09773) has filed another complaint against VoIP-Pal.com, Inc. (VPLM), asking the Northern District of California for declaratory judgments that it has not infringed the publicly traded NPE’s family of “mobile gateway” patents. VPLM has turned to this family for assertion in the Western District of Texas—against Huawei and Samsung most recently, but against others as well—after patents from a first family met Alice demises in Northern California. In response to VPLM’s actions, Twitter has repeatedly filed cases there, which the court has declined to dismiss in response to the defendant’s motions, Twitter now pleading that “[o]n information and belief, VoIP-Pal plans to file a lawsuit against Twitter for infringement of the Mobile Gateway patents after Twitter’s 2021 DJ Action is dismissed”.
