1111.7(M) Limitation of Claim
If the works contain an appreciable amount of material that has been previously published or previously registered, the applicant should exclude that material from the claim. Likewise, applicants should disclaim material that is owned by a third party or material that is in the public domain.
Specifically, the applicant should briefly describe this material on the Limitation of Claim screen in the field marked Material Excluded. The U.S. Copyright Office will assume the applicant intends to register all copyrightable aspects of the works that have not been expressly disclaimed in this portion of the application.
If the material was previously registered with the U.S. Copyright Office, the applicant should also provide the registration number and year of registration that has been assigned to that material. If the Office issued multiple registrations for this material, the applicant should provide the number and year for the most recent registration.
For additional information concerning the U.S. Copyright Office’s practices and
procedures for limiting the scope of a copyright claim, see Chapter 600, Section 621.
