Copyright is authorship, which refers to the rights (including property rights and personal rights) that authors of literary, artistic, and scientific works enjoy over their works. There are two ways to obtain copyright: automatic acquisition and registration acquisition. In China, according to the copyright law, copyright automatically becomes available upon completion of the work. The so-called completion is relative. As long as the object of creation meets the statutory conditions for the composition of a work, it can be protected by copyright law as a work. Its functions are as follows: 1. It can help copyright owners and related rights holders effectively exercise their rights and provide security protection. 2. Copyright is an intangible right that is embodied in tangible objects, including moral rights and property rights. 3. Therefore, copyright is also a human right and a kind of property. Infringing on someone else's copyright is like stealing someone else's money. 4. Piracy is as disgraceful as theft. The protection of intellectual property rights is not only to protect the personal interests of copyright owners, but also to safeguard public interests, safeguard national interests, maintain national economic order, and promote social development. Legal basis: Article 1 of the Copyright Law of the People's Republic of China protects the copyrights of authors of literary, artistic and scientific works, as well as copyright-related rights and interests, and encourages the publication of works that are beneficial to the construction of socialist spiritual civilization and material civilization. This law is formulated in accordance with the Constitution to create and disseminate, and promote the development and prosperity of socialist cultural and scientific undertakings.
