Patent applications are the same everywhere.
To apply for a patent, you can entrust a patent agency to handle it, or you can submit the patent application documents to the Patent Office yourself. The specific process is as follows:
1) Prepare patent application documents (which may include claims, description, description drawings, abstract, and abstract drawings).
2) Fill in the patent application request form (including invention title, applicant, inventor and related information, etc.).
3) Pay the patent application fee.
4) After submitting these to the Patent Office, you can obtain the application date and application number, which will be used as the unique number for future patent office examination. The official acceptance notice will be issued within two weeks after the application date.
5) The Patent Office will examine and issue a notice of examination opinion or a notice of correction, which requires the applicant to respond within a specified time limit. After the examination is finally passed, the Patent Office will issue an authorization notice indicating that it agrees to the authorization.
6) The patent authorization announcement will take effect after the applicant registers for authorization (pays the money).
