624.2 (C) Application Certified by an Owner of One or More – but Less than All – of the Exclusive Rights or That Party’s Duly Authorized Agent
If the author has assigned one or more – but less than all – of the rights in the work to another party, then the author should be named as the copyright claimant. In this situation, the application may be certified by the author, the transferee, or their respective agents.
If the author assigned all of his or her rights under copyright to a third party and that transferee, in turn, assigned some – but not all – of those rights to an exclusive licensee, the author should be named as the copyright claimant. However, the author, the transferee, the exclusive licensee, or their respective agents may certify and submit an application to register the work with the U.S. Copyright Office.
For further discussion of this issue, see Section 619.7 and 619.9 and Chapter 400, Sections 405 and 407.
