On December 1, the US Copyright Office replaced its directory of designated agents for receipt of Digital Millennium Copyright Act (DMCA) notices of claimed infringement with a new electronic system. As part of this process, the Copyright Office is making a number of changes to the rules for these designations, including: (1) requiring website operators and other "service providers" who used the old system to re-designate their agents through the new system before the end of 2017; (2) requiring periodic renewal of agent designations; (3) modifying the types of agents that can be designated; and (4) changing the fee structure to a $6 flat fee per designation, amendment and renewal.
