The relationship between a job inventor and his unit is a kind of labor contract relationship, which is manifested in the relationship between employees and employers in capitalist countries. In the patent law, this relationship is embodied in the ownership of the invention and creation completed by employees, that is, whether the invention and creation completed by employees are job inventions or non-job inventions. In principle, the solution to this problem should follow the principle of "the contract is superior to the law", that is, the ownership of the right of invention and creation should be solved first in accordance with the agreement in the labor contract.
