The object of intellectual property protection is information with commercial value, which Mr. Wu calls knowledge products. This kind of information is the product of labor, which has value and use value, and can bring economic benefits to its owners. Its immateriality is different from materiality. Because of its immateriality, infinite dissemination and permanence determined by immateriality, it can be used by many people at the same time or successively in the same area or different areas. The special adjustment method of intellectual property law and the characteristics of intellectual property rights are different from those of general property rights. The most important of these features are the geographical acquisition and exercise of intellectual property rights, the distributability and statutory limitation of copyright, patent rights and other rights. On the other hand, because information and general material property belong to property, they can be controlled and used by human beings, controlled by the controllers themselves and exchanged. Therefore, intellectual property has the basic characteristics of real right, so intellectual property is also called quasi-real right. We should not only see the difference between intellectual property rights and general property rights, but also see the similarities between intellectual property rights and general property rights. One-sided emphasis on one aspect while denying the other is not conducive to the theoretical research and system construction of intellectual property law.
