join in signing the notice of termination under clause (4) of subsection (a), but with the following limitations:
- (1) A derivative work prepared under authority of the grant before its termination may continue to be utilized under the terms of the grant after its termination, but this privilege does not extend to the preparation after the termination of other derivative works based upon the copyrighted work covered by the terminated grant.
- (2) The future rights that will revert upon termination of the grant become vested on the date the notice of termination has been served as provided by clause (4) of subsection (a). The rights vest in the author, authors, and other persons named in, and in the proportionate shares provided by, clauses (1) and (2) of subsection (a).
- (3) Subject to the provisions of clause (4) of this subsection, a further grant, or agreement to make a further grant, of any right covered by a terminated grant is valid only if it is signed by the same number and proportion of the owners, in whom the right has vested under clause (2) of this subsection, as are required to terminate the grant under clauses (1) and (2) of subsection (a). Such further grant or agreement is effective with respect to all of the persons in whom the right it covers has vested under clause (2) of this subsection, including those who did not join in signing it. If any person dies after rights under a terminated grant have vested in him or her, that person’s legal representatives, legatees, or heirs at law represent him or her for purposes of this clause.
- (4) A further grant, or agreement to make a further grant, of any right covered by a terminated grant is valid only if it is made after the effective date of the termination. As an exception, however, an agreement for such a further grant may be made between the persons provided by clause (3) of this subsection and the original grantee or such grantee’s successor in title, after the notice of termination has been served as provided by clause (4) of subsection (a).
- (5) Termination of a grant under this section affects only those rights covered by the grant that arise under this title, and in no way affects rights arising under any other Federal, State, or foreign laws.
- (6) Unless and until termination is effected under this section, the grant, if it does not provide otherwise, continues in effect for the term of copyright provided by this title.
§ 204. Execution of transfers of copyright ownership
(a) A transfer of copyright ownership, other than by operation of law, is not valid unless an instrument of conveyance, or a note or memorandum of the transfer, is in writing and signed by the owner of the rights conveyed or such owner’s duly authorized agent.
(b) A certificate of acknowledgment is not required for the validity of a transfer, but is prima facie evidence of the execution of the transfer if—
- (1) in the case of a transfer executed in the United States, the certificate is issued by a person authorized to administer oaths within the United States; or
- (2) in the case of a transfer executed in a foreign country, the certificate is issued by a diplomatic or consular officer of the United States, or by a person authorized to administer oaths whose authority is proved by a certificate of such an officer.
§ 205. Recordation of transfers and other documents
(a) Conditions for Recordation.—Any transfer of copyright ownership or other document pertaining to a copyright may be recorded in the Copyright Office if the document filed for recordation bears the actual signature of the person who executed it, or if it is accompanied by a sworn or official certification that it is a true copy of the original, signed document.
