Who are the inventors and designers in the patent application?

A patent applicant is a person who applies to the Patent Office for a patent for invention. Generally speaking, the inventor, designer and patent applicant are the same person. However, in the following cases, the applicant for a patent is a person other than the inventor or designer: 1) Others obtained the right to apply for a patent for invention-creation from the inventor or designer through a contract and applied for a patent. It should be noted that if an inventor or designer transfers his patent application right after filing a patent application, he shall submit the transfer contract to the Patent Office for the record, and the contract shall take effect after being registered by the Patent Office. 2) The successor of the invention-creation obtains the right to apply for a patent for the invention-creation through inheritance. To inherit the patent right being applied for, a request must be made to the Patent Office to change the applicant. 3) The law directly grants the patent application right to others other than the inventor or designer. The applicant for service invention-creation is the unit where the inventor or designer works.
