1. Acceptance stage: After the patent applicant submits the application documents to the Patent Office, the Patent Office determines the application date, gives the application number, checks the list of documents, and issues an acceptance notice.
2. Preliminary examination stage: if the accepted patent application pays the application fee according to the regulations, it will automatically enter the preliminary examination stage. Before the preliminary examination, the application for a patent for invention must be examined in confidentiality, and if confidentiality is required, it shall be handled in accordance with the confidentiality procedures.
