Legal subjectivity:
The relationship between a service inventor and his or her employer is a labor contract relationship, which in capitalist countries is the relationship between an employee and an employer. In patent law, this relationship is embodied in the issue of ownership of rights for inventions and creations completed by employees, that is, whether the inventions and creations completed by employees are service inventions or non-service inventions and creations. In principle, the solution to this issue should follow the principle of "contracts trump the law", that is, issues related to the ownership of inventions and creations should first be resolved in accordance with the provisions of the labor contract.
