Content Distribution Patents Asserted Again in Litigation, This Time by Monument SubsidiaryApril 13, 2017
Pure Data Systems, LLC, a subsidiary of Monument Patent Holdings, LLC, has launched a new campaign over two patents (5,999,947; 6,321,236) generally related to the distribution of database differences and previously asserted in litigation. Pure Data’s complaints accuse CBS (CBS Interactive, CNET) (6:17-cv-000210), Time Warner (CNN Interactive) (6:17-cv-000209), Twenty-First Century Fox (Fox Broadcasting, Fox News, Fox Sports) (6:17-cv-000211), and USA Today (6:17-cv-000208) of infringement through the process by which content delivered to their websites and mobile apps is replicated across multiple servers. Xanthus Data Technologies, LLC, an affiliate of Daniel F. Perez, asserted both patents against Citrix and LinkedIn in a short-lived 2015 litigation campaign.

A new Daniel Perez entity, Xanthus Data Technologies, LLC, filed suit against Citrix (2:15-cv-00715) and LinkedIn (2:15-cv-00777). The entity asserts two patents, both of which relate to database management (5,999,947, 6,321,236). The patents-in-suit originated with Arkona, Inc. and were assigned to Intellectual Ventures Asserts 13 LLC in March 2015. In April of this year, the patents were assigned first to IQ Holdings, LLC and then to Xanthus. They have not been previously asserted in litigation. Many of Citrix’s cloud-based products are accused of infringing the patents-in-suit.
