An inventor is a person who has completed his invention and creation and put forward creative opinions on the conception and concretization of his invention and creation; A patent applicant is a person who applies to the Patent Office for a patent for invention and creation. Generally speaking, the inventor is a patent applicant, but there are differences between them, such as service invention; The patentee is the person who enjoys the patent right, which is different from the patent applicant. An applicant for a patent applies for an invention-creation. If approved, the applicant obtains the patent right and is the patentee. If it is not approved, it will not enjoy the patent right. In addition, the patent application right and patent right can be transferred separately. Patent inventor: the inventor or designer mentioned in the patent law refers to a person who has made creative contributions to the substantive characteristics of invention and creation. In the process of completing the invention-creation, a person who is only responsible for organizing the work, providing convenience for the utilization of material and technical conditions or engaging in other auxiliary work does not belong to the inventor or designer. Patent applicant: refers to the natural person, legal person or other organization that has the right to apply for a patent for invention and creation according to the law or the contract; In other words, the patentee is a natural person, legal person or other organization qualified to file a patent application for invention-creation. The applicant before the patent is granted is called the patentee: the patentee is consistent with the patentee: the right to apply for a patent is the basis of the patent, and the patentee becomes the patentee after the patent application filed by the patentee is approved. The applicant and the inventor may or may not be the same person. For example, if you apply for a patent for an invention made to complete the company's task, the company should be a legal person applicant. If the patent is authorized, the company is the patentee. Patent authorization must be granted to the applicant.
Patent inventors can only be individuals, not units, and enjoy the right to be rewarded and signed, but they have no right to use, possess or dispose of the patent alone, only to change it and not to transfer it; Patent applicants or patentees can be individuals and units, with exclusive rights (exclusive exploitation of this patent), licensing rights (licensing others to exploit this patent) and transfer rights (patent application rights and patent rights can be transferred).
