Iron Gate Security, Inc., a subsidiary of FORM Holdings Corp. (f/k/a Vringo, Inc.), has filed a sixth case, this one against APX Holdings (Vivint) (1:17-cv-01911), in the campaign that it began in September 2013. As in the prior five cases, the complaint asserts a single patent (6,288,641) generally related to mobile apps and surveillance equipment used for remote monitoring of, e.g., a home or office. The accused products are cameras, backend servers, control interfaces, and mobile apps used in concert for remote surveillance.

Throughout November 2015, an inordinate number of cases were filed by NPEs apparently motivated to get to court before December 1 to avoid changes to the Federal Rules of Civil Procedure that took effect on that date. Among those filing November cases were several subsidiaries of publicly traded patent assertion entities (PAEs), including Collabo Innovations, Inc. (a subsidiary of Wi-Lan Inc.); Iron Gate Security, Inc. (a subsidiary of Vringo, Inc.), and Endeavor MeshTech, Inc. (a subsidiary of Endeavor IP, Inc.).
