What are the legal restrictions on intellectual property rights?

Although intellectual property is a private right, although the law also recognizes its exclusiveness, but because people's intellectual achievements are highly public, closely related to social culture and industrial development, it is not suitable for anyone to monopolize for a long time, so the law stipulates many restrictions on intellectual property:

First, from the perspective of the occurrence of rights, the law stipulates various positive and negative conditions and publicity methods. For example, the occurrence of patent rights requires application and examination and approval. There are various conditions for the invention, utility model and design to be granted patent rights (Articles 22 and 23 of the Patent Law), but some matters are not granted patent rights (Article 25 of the Patent Law). Although there are no restrictions on the application, examination and registration of copyright, there are also restrictions in Articles 3 and 5 of the Copyright Law.

Second, the law has special provisions on the term of rights. This is a big difference between intellectual property and ownership.

Third, the obligee has a certain obligation to use or implement. The law provides for compulsory license or compulsory license system. For copyright, the law also stipulates a fair use system.
