This past May, after the last of the cases from the first wave of litigation in this campaign had been dismissed, Serenitiva LLC (an affiliate of IP Edge LLC) filed a second wave. The NPE hit Freshdesk, Zendesk, and TalkDesk, accusing each of infringing a single patent, generally related to call tracking and resolution management, through provision of their Customer Relationship Management (CRM) systems. Serenitiva also sued, in separate complaints, six customers of those companies. Now that all nine of those May cases have been dismissed, the NPE has again filed a new wave, this time against Mitel Networks (6:17-cv-00461), SAP (6:17-cv-00460), and Vocalcom (6:17-cv-00463), targeting the contact center software of each.
