503.5 (B) Unclaimable Material: Previously Registered Material
The following chart provides a representative example of a work that contains previously registered material.
| Work of Authorship | Excluded Material | New Authorship |
| Feature film based on an unpublished screenplay | Unpublished screenplay (Reg. No. PAu 9-999-999) | Motion picture |
In this example, the unpublished screenplay has been previously registered with the U.S. Copyright Office, but the feature film has not. The applicant may register the new authorship that the author contributed to the motion picture. The previously registered screenplay should be excluded from the claim using the procedure described in Chapter 600, Section 621.8 (F).
