The Digital Millennium Copyright Act (DMCA) provides limited immunity from copyright infringement claims to certain types of websites and other online service providers. To qualify for such safe-harbor immunity, such providers must designate an agent to receive requests to remove infringing materials.
As of December 1, 2016, the Copyright Offices now requires that such providers designate their DMCA agents electronically through an online portal at the Copyright Office. And as of December 31, 2017, any previously-filed designations will be rendered ineffective unless they have been updated through that portal.
