Rothschild Broadcast Distribution Systems, LLC (RBDS), an affiliate of prolific inventor and frequent plaintiff Leigh M. Rothschild, has added its first 2018 cases to the campaign that it began back in March 2015. The new defendants are APX Group (Vivint) (2:18-cv-00102) and Link Interactive (1:18-cv-00014), sued in the District of Utah, and Frontpoint Security Solutions (1:18-cv-00187), sued in the District of Delaware. The sole patent patent-in-campaign broadly relates to the storage of broadcast content, with the latest infringement accusations focused on the provision of smart home systems, specifically those offering storage of security video footage.
