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.).
