The registration of a copyright is not evidence that the copyright is valid.

Copyright Registration

The process of recording a copyright with the copyright office of a country, which provides legal benefits such as public record and legal evidence of copyright ownership.

Copyright

The exclusive right of authors to publish, print, or sell an intellectual production for a statutory period of time. A copyright has the same monopolistic nature as a patent or trademark, but it differs in that it applies exclusively to works of art, literature, and other works of authorship, including computer programs.
