Secure Domain Patent Seen in Litigation Again, This Time by IPVal’s Guardian Mail

  • July 31, 2016

Guardian Mail, LLC, an affiliate of patent monetization firm IP Valuation Partners LLC (IPVal), has filed suit asserting a single patent (6,829,613) against Entrust (2:16-cv-00833). The ‘613 patent generally relates to scanning outgoing messages from a secure domain for possible violations of a security policy. The NPE’s complaint accuses Entrust of infringement through the provision of secure servers (the Entrust Entelligence Messaging Server, together with the Entrust Entelligence Content Control and Monitoring servers). This campaign is the second in which the ‘613 patent has been asserted in litigation.
