2. The applicant can be an inventor or an inventor. The patentee applies for authorization, and the applicant is the patentee. Patent authorization must be granted to the applicant.
3. If someone applies for a patent (non-service invention), both the applicant and the inventor are natural persons, then the inventor and patentee embodied in the patent certificate (the applicant embodied in the invention patent, utility model patent and design patent application) are the same person.
4. The word "applicant" will not appear on the patent certificate, only the word "patentee" will appear. The patentee on the patent certificate is the patent applicant (application for invention patent, application for utility model patent and application for design patent).
5. Patent applicant refers to the entity or individual that filed the patent application. After the patent examination is passed, the patent applicant becomes the patentee and has the right to claim the patent granted by the patent law. In short, the applicant is the name of the patent that is still under examination. After the examination is passed, the identity becomes the patentee, and the patentee can sue the person who owns the patent.
