After an early September reboot of two earlier litigation campaigns and the start of a third, Callstat Solutions LLC has began a fourth, suing Sync.com (6:21-cv-00918) and Zoom Video Communications (1:21-cv-01314) over a single patent generally related to “dynamically indicating a status of a communication system” through a “graphical user interface”. The asset is one of thousands assigned by Intellectual Ventures LLC (IV) to Hanger Solutions, LLC in December 2019, as are the patents-in-suit in Callstat’s other three campaigns, two of which Callstat has just expanded as well: one to add a case against ZTE (6:21-cv-00919) and the second to sue Check Point Software (3:21-cv-02134) and McAfee (2:21-cv-00352).
