Does the patent law require the age of the patentee?

There is no age limit and it can be inherited. As long as a natural person has made substantial contributions to an invention, he can become an inventor, regardless of age, nationality, political rights, mental health and other conditions. If you are an employee of a company, enterprise or unit, the invention you make belongs to the invention of duty. Unless otherwise agreed, the right to apply for a patent belongs to the unit (the patent applicant is the unit and the application fee is paid by the unit). After obtaining the patent, the right belongs to the unit, and you can get some rewards or remuneration from the unit), but the inventor is still you, and you have the right to sign the application documents. If your invention is not a service invention, then the applicant is yourself (the application fee is paid by yourself, and it will be your own after you get the patent right).
