The Copyright Office yesterday issued a “Final Reminder” to Internet Services that want to be able to assert that they are insulated from Copyright liability for content posted on their sites by third-parties. Services need to be sure that they have used the Copyright Office’s new online system to the register the names of their designated agents who can be served with take-down notices from copyright owners demanding that content that infringes on intellectual property rights be removed from the website. For that registration to be valid to preserve the “safe harbor” of Section 512 of the Copyright Act for copyright infringement contained in third-party content, electronic registration of the agent for take-down notices must be completed by December 31. Previous registrations done in the Copyright Office’s paper system will no longer be valid after the end of this year. For more information, see our articles here and here.
