China National Intellectual Property Administration promulgated the Measures for the Administration of Patent Priority Examination, which came into force on August 1 day, 2065438. If the applicant meets the requirements and the General Administration agrees to give priority to the examination, the application for a patent for invention shall issue a notice of the first examination opinion within 45 days, and the case shall be closed within one year. Specifically, for the application or case that China National Intellectual Property Administration agrees to give priority to the examination, the application for a patent for invention will issue the first notice of examination opinions within 45 days from the date of agreeing to give priority to the examination, and the case will be closed within one year. This means that the examination time of invention patents can be shortened to one year through priority examination (that is, expedited treatment). However, it should be noted that this does not mean that all invention patent applications can be authorized within one year through expedited processing, because authorization needs to meet other conditions, such as substantive examination found no reason for rejection. In addition, the specific time for expedited processing of invention patents may also be affected by other factors, such as the integrity of application documents and the efficiency of examiners. Therefore, although expedited processing can shorten the examination time, it does not guarantee that all invention patent applications can be authorized in the shortest time. To sum up, the expedited examination of invention patents can be completed within one year at the earliest, and it is possible to obtain authorization, but the specific time still needs to be determined according to the specific circumstances. At the same time, it should be noted that expedited processing cannot guarantee that all invention patent applications can be successfully authorized, and other conditions and requirements need to be met.
