The increasing frequency with which the Copyright Office has inserted itself into policy debates raises questions about the scope of its expertise and authority. An illustrative example of how the Office’s opinions can cause problems occurred earlier this year. During the Department of Justice’s Antitrust Division inquiry into how performance rights organizations (PROs) ASCAP and BMI license songs with multiple authors where not every author is a member of the PRO (i.e., where either PRO represents only a ‘fraction’ of the ownership stake in the song), a member of Congress sought out the opinion of the Copyright Office, and the Office responded. Although it’s unremarkable for an agency to offer its opinion in response to a lawmaker request, it is remarkable for that agency to reach into unfamiliar areas of law, ignore basic public policy concerns in that area of law, and offer its own unqualified judgment on matters properly within the jurisdiction of another agency.
