(1) Copyright is an intellectual property belonging to different fields from trademark right and patent right. People usually divide intellectual property rights into industrial property rights and literary and artistic property rights according to their fields. The former includes trademark rights and patent rights, while the latter mainly refers to the rights of authors and disseminators of works. The acquisition of industrial property rights must be approved by the administrative department in accordance with the law, while the acquisition of copyright is based on the occurrence of certain legal facts (that is, the completion of the creation of the work) without the confirmation of the administrative department.
(2) Compared with trademark rights and patent rights, copyright has obvious personal characteristics, and the right of signature in copyright is the most powerful proof.
