621.9 (F) De Minimis Material Claimed in the New Material Included Field or Space 6 (B)
The material described in the New Material Included field or in space 6 (B) must be copyrightable. If the material claimed in that field/space is de minimis, the U.S. Copyright Office may ask for permission to remove that claim from the application, or in appropriate cases may add an annotation to clarify that the registration does not cover that element. If the claim appears to be limited to the de minimis material or if there appears to be no other basis for asserting a valid claim in the work, the Office will refuse registration.
