Tekvoke LLC, an entity apparently associated with IP Edge LLC, has begun a new litigation campaign for the Texas monetization firm, suing 8x8 (3:19-cv-07734), Dialpad (3:19-cv-07733), Digium (1:19-cv-02205), RingCentral (3:19-cv-07735), and Vonage (1:19-cv-02206). The sole patent asserted, broadly concerning an Internet-based telephone system, is one of roughly 30 former Panasonic patents that IP Edge picked up at the beginning of 2017.
