17 U.S.C. § 1507: Effect of proceeding

A determination of the Copyright Claims Board shall not preclude litigation or relitigation as between the same or different parties before any court or tribunal, or the Copyright Claims Board, of the same or similar issues of fact or law in connection with claims or counterclaims not asserted or not finally determined by the Copyright Claims Board. A determination of ownership of a copyrighted work for purposes of resolving a matter before the Copyright Claims Board may not be relied upon, and shall not have any preclusive effect, in any other action or proceeding before any court or tribunal, including the Copyright Claims Board. Except to the extent permitted under this subsection and section 1508, any determination of the Copyright Claims Board may not be cited or relied upon as legal precedent in any other action or proceeding before any court or tribunal, including the Copyright Claims Board. A proceeding before the Copyright Claims Board shall not have any effect on a class action proceeding in a district court of the United States, and section 1509(a) shall not apply to a class action proceeding in a district court of the United States. opt out of the class action, in accordance with regulations established by the Register of Copyrights; or seek dismissal under section 1506(q)(3) of the proceeding before the Copyright Claims Board. Except as permitted under this section and section 1508, a submission or statement of a party or witness made in connection with a proceeding before the Copyright Claims Board, including a proceeding that is dismissed, may not be cited or relied upon in, or serve as the basis of, any action or proceeding concerning rights or limitations on rights under this title before any court or tribunal, including the Copyright Claims Board. notice of the commencement of the Copyright Claims Board proceeding is provided by the claimant to the service provider’s designated agent before the service provider replaces the material following receipt of a counter notification under section 512(g); and the claim brought alleges infringement of the material identified in the notification of claimed infringement under section 512(c)(1)(C). The failure or inability to assert a counterclaim in a proceeding before the Copyright Claims Board shall not preclude the assertion of that counterclaim in a subsequent court action or proceeding before the Copyright Claims Board. If a party has timely opted out of a proceeding under section 1506(i) or is dismissed from a proceeding before the Copyright Claims Board issues a final determination in the proceeding, the determination shall not be binding upon and shall have no preclusive effect with respect to that party.
