The United States Copyright Office is undertaking a public study to evaluate the impact and effectiveness of the DMCA safe harbor provisions contained in 17 U.S.C. 512. Among other issues, the Office will consider the costs and burdens of the notice-and-takedown process on large- and small-scale copyright owners, online service providers, and the general public. The Office will also review how successfully section 512 addresses online infringement and protects against improper takedown notices. To aid in this effort, and to provide thorough assistance to Congress, the Office is seeking public input on a number of key questions.
