Abstract:The definition of the subject and object of intellectual property has not been formed an unanimity for a long time, and it has adverse effect on the systematization of intellectual property law. Judging from the method of defining the subject of traditional civil rights, the subject of intellectual property is knowledge and information, and it is valuable, reproducible and could be distinguished from the existing knowledge and information. It specifically includes works, patented technology solutions, trademarks and other undisclosed information. According to the nature of rights, the object of intellectual property is the benefit result from using these knowledge and information, the property attribute of the right object and the uniqueness of the right subject are the dual basis for intellectual property to become an independent kind of civil rights.
