On March 6, 2012, ALJ Essex denied the Trek Complainants’ motion for leave to supplement their opening infringement expert report.  Trek contended that the Commission’s recent decision in Certain Electronic Devices with Image Processing System, Components Thereof, and Associated Hardware, Inv. 337-TA-724, changed the law and provided good cause for the supplementation. ALJ Essex determined that the proposed supplementation concerned contributory infringement and Electronic Devices did not change the law on contributory infringement.  As a result, ALJ Essex found that good cause did not exist to permit supplementation.
