How to make a request for examination of patent substance?

Only when an application for a patent for invention makes a request for substantive examination needs to go through this procedure. The actual trial request can be submitted at the same time as the application or after the application, but it should be submitted within 3 years from the date of application at the latest. If the application is not submitted within the time limit without justifiable reasons or is regarded as not submitted due to unqualified procedures, the application shall be deemed to be withdrawn. When the Patent Office deems it necessary, it may examine the application for a patent for invention on its own. Where a request for substantive examination is made, it shall be submitted separately. The request for substantive examination will not take effect until the substantive examination fee is paid. However, if the actual examination fee is not paid after the actual examination request is made, the Patent Office will not immediately issue a notice that the actual examination request is deemed not to have been made, but wait for three years from the date of application. If the applicant still fails to pay the substantive examination fee or fails to pay in full, a notice that the application is deemed to be withdrawn will be issued. If the applicant makes a request for real trial and pays the substantive examination fee, the Patent Office will examine the request for real trial. Do not meet the requirements, the actual trial request will be regarded as a notice of failure to submit or a notice of correction, and the reasons for failure to submit will be stated. Upon receipt of the notice of correction, the applicant shall make corrections within the time limit prescribed by the examiner. If the applicant is deemed not to have given notice after receiving the actual trial request, it shall resubmit the actual trial request that meets the requirements within 3 years from the date of application. If the actual trial request passes the examination, the Patent Office will publish it in the patent bulletin. If it is not corrected or still does not meet the requirements after the expiration of the period, the Patent Office will issue a notice of request for substantive examination to inform the applicant. If the substantive examination request is qualified, the examiner will issue a notice to enter the substantive examination procedure and inform the applicant before entering the substantive examination. The applicant shall, at the same time as submitting the request for substantive examination, submit the reference materials related to his invention before the filing date (before the priority date if priority is claimed). Where an application for a patent for invention is filed in a foreign country, the Patent Office may require the applicant to submit the information retrieved from the examination of his application in that country or the information on the examination results within a specified time limit; If the application is not submitted within the time limit without justifiable reasons, the application shall be deemed to have been withdrawn. When making a request for substantive examination, the applicant may, within 3 months from the date of receiving the notice from the Patent Office that the application for a patent for invention has entered the substantive examination stage, take the initiative to propose amendments to the application for a patent for invention.
