Copyright refers to the rights (including property rights and personal rights) enjoyed by authors of literary, artistic and scientific works. There are two ways to obtain copyright: automatic acquisition and registration acquisition. In China, according to the copyright law, works are automatically copyrighted upon completion. The so-called completion is relative, as long as the object of creation has met the statutory conditions for the composition of the work, it can be protected as a work by copyright law. Its functions are as follows: 1. It can help copyright owners and related rights holders to effectively exercise their rights and provide security. 2. Copyright is an intangible right, and it is also embodied by tangible things, including moral rights and property rights. 3. Therefore, copyright is also a human right and a kind of property. Infringing others' copyright is like stealing others' money. 4. Piracy is as contemptible as theft. Protecting intellectual property rights is not only to protect the personal interests of copyright owners, but also to safeguard public interests, national interests, national economic order and social development. Legal basis: Copyright Law of the People's Republic of China Article 1 This Law is formulated in accordance with the Constitution for the purpose of protecting the copyright of authors of literary, artistic and scientific works and their rights and interests related to copyright, encouraging the creation and dissemination of works beneficial to the construction of socialist spiritual civilization and material civilization, and promoting the development and prosperity of socialist culture and scientific undertakings.
