What is the specific procedure of patent application?

If the applicant fails to go through the formalities for actually hearing the request, the Patent Office will wait for the applicant to go through the formalities for actually hearing the request; If, after three years from the date of application, the applicant fails to make a request for actual trial or the request for actual trial does not take effect, the application shall be deemed to have been withdrawn. Applications that enter the actual trial procedure will wait for the actual trial in the order of entering the actual trial procedure. In the actual trial, the examiner will, on the basis of retrieval, conduct a comprehensive review of whether the patent application is novel, creative, practical and other substantive conditions stipulated in the patent law. Upon examination, if it is found that it does not meet the authorization conditions or there are various defects, it shall notify the applicant to state his opinions or make amendments within the specified time (the time limit for the first review of the reply notice is 4 months). If the applicant fails to reply within the specified time limit, the application shall be deemed to be withdrawn. After at least one reply or amendment, it still does not meet the requirements, and the application is rejected. Due to the complexity of the actual trial, the review period generally takes 1 year or longer. If the application for a patent for invention finds no reason for rejection in the substantive examination, or the defects have been eliminated after the applicant modifies the statement, the examiner will issue a notice of authorization, and the application will enter the stage of authorization preparation as required.
