There must be. As long as there is something similar to the contract, it should be confirmed. The original author of copyright works and his heirs enjoy several basic rights. They have the exclusive right to use or license others to use their works under agreed conditions. The creator of a work may prohibit or allow: reproduction of a work in various forms, such as printed matter or sound recordings; Public performance, such as in the form of drama or musical works; Record it, for example, in the form of CD, disk or video tape; Broadcast by radio, cable TV or satellite; Translate into other languages, or adapt, for example, adapt a novel into a film and television script. Many creative works protected by copyright need a lot of distribution, dissemination and capital investment to promote (such as publications, sound recordings and movies); Therefore, creators often sell the rights of their works to individuals or companies that can best promote their works in order to get remuneration, which is often paid when they actually use their works, so it is called royalties. These economic rights have a time limit, which is 50 years after the death of the creator according to the relevant treaties of the World Intellectual Property Organization. Domestic law may stipulate a longer time limit. This time limit enables creators and their heirs to obtain economic benefits within a reasonable time. Copyright protection also includes spiritual rights, involving the right to show the identity of the author of the work and the right to oppose the modification of the work that may damage the reputation of the creator. Creators, that is, copyright holders of works, can enforce this right through administrative means or courts by inspecting houses and looking for evidence of illegally produced pirated articles related to protected works. The obligee may also request the court to order the cessation of these illegal acts, and may request damages to compensate him for his loss in economic remuneration and recognition.
