VoIP-Pal.com Inc. (VPLM) has filed separate Western District of Texas lawsuits against a mostly familiar set of defendants—Alphabet (Google) (6:21-cv-00667), Amazon (6:21-cv-00668), Apple (6:21-cv-00670), AT&T (6:21-cv-00671), Facebook (6:21-cv-00665), T-Mobile (6:21-cv-00674), and Verizon (6:21-cv-00672)—asserting a family of two patents new to litigation. The publicly traded NPE describes the patents as describing “systems, apparatuses and methods for providing an access code to roaming mobile communication devices such as smartphones, to enable access to suitable communication routing infrastructure, wherein the selection of the communication channel for a call can be optimized based on the calling device’s current location”, with infringement allegations targeting the “calling systems” of each defendant, comprised of servers and a host of interconnected devices. VPLM’s first campaign is a somewhat storied affair, in various district courts as well as before the PTAB.
