Trademark registration certificate is not a reasonable form of proof of copyright ownership.

The trademark registration certificate is used to prove the legal registration of the trademark and the establishment of trademark rights. A trademark registration certificate is usually issued by a trademark registration agency or an intellectual property agency to confirm the owner of the trademark and the validity of the trademark registration.

Copyright refers to the legal right to independent creation of literary, artistic and scientific works. Copyright ownership can usually be confirmed through other forms of proof, such as:

1. Copyright registration certificate: In some countries/regions, the copyright registration agency will issue a copyright registration certificate to prove the registration of the copyright. and ownership. The copyright registration certificate is valid evidence of ownership.

2. Original creation: Copyright ownership can be proven by the original version or document of the creation. This can include original materials such as written works, artwork, musical compositions, software code, etc.

3. Public release: By publicly releasing the work in a public place or on the Internet, you can prove the ownership of the copyright. Public release timestamps, author signatures, and traceability of works can all be used as evidence of ownership.

Copyright registration and trademark registration are two different fields of intellectual property, with different purposes and legal effects. Therefore, a trademark registration certificate is not regarded as reasonable proof of copyright ownership.

If you need to prove copyright ownership, it is recommended to register the copyright according to local laws or take other appropriate methods to ensure the proof and protection of ownership.
