VoIP-Pal.com Sues T-Mobile and Verizon over Previously Unasserted Claims from Previously Asserted Patents

June 1, 2024

VoIP-Pal.com Inc. (VPLM) has sued Deutsche Telekom (T-Mobile) (6:24-cv-00299) and Verizon (Verizon Wireless) (6:24-cv-00298)—repeat defendants in this long-running campaign—over several familiar patents. The cases have been filed in the Western District of Texas, VPLM’s preferred venue, where a prior case against each defendant, as well as a suit against Amazon, remains active. For this pair of new complaints, VPLM turns to claims from two of the three familiar patents-in-suit, claims not asserted in prior litigation and therefore not invalidated under Alice in that litigation; as to the third asserted patent, in suit against only T-Mobile, VPLM points to three claims the patentability of which was confirmed in a recent ex parte reexamination (EPR).
