2133 Abandonment of Copyright
When a renewal claim is based on an original registration record that refers to a recorded document purporting to abandon the copyright in the work, the U.S. Copyright Office may register the renewal claim if, after advising the renewal applicant of the recorded document, the applicant verifies that no other action was taken to notify the public of the intent to abandon the copyright and reasserts the claim to the renewal copyright. If the author or proprietor took further action to notify the public of the intent to abandon the copyright (such as authorizing the publication of a statement in a number of well-known newspapers that the property rights in a particular work would no longer be enforced), the Office may refuse to register the renewal claim based on the original registration record.
