Does the patent applicant have to be a company legal person?

Patent applicants can be individuals (natural persons) or enterprises and institutions. After the patent is authorized, the patent applicant becomes the patentee. Whether all patent applicants fill in individuals or units depends on who owns this technological achievement. If this technological achievement is completed by an individual independently, instead of undertaking the work and tasks of the unit itself, and without using the material and technical data of the unit, then this patent achievement belongs to an individual, and the individual who completes the patent is the applicant, and after authorization, the individual is the patentee. If this technological achievement is to complete the work and tasks of the unit, mainly using the material equipment and technical data of the unit, then this technological achievement belongs to the service invention, and the patent applicant is the unit. At this time, the applicant can only fill in the unit, not the legal representative. After authorization, the unit is the patentee.
