As far as I know, patent applications are relatively professional and formal. Generally, the ones written by individuals are not very standardized, and it is difficult to pass the application. Therefore, nowadays, patent applications are generally done through agents. , they all need to pass relevant national examinations to obtain qualifications before they can act as agents. You can consult them and you should be able to get better answers. Agents require a certain fee, but it seems that the asking price is not very high
