How long does it take to authorize the invention patent?

After inventing something, you should apply for a patent as soon as possible, because it is possible that the other party will apply for a patent before you, so your efforts will be in vain. There is no specific time limit for the actual examination and authorization of patents. According to the above description, I have compiled the relevant legal knowledge about how long it will take to authorize the invention patent, hoping to help you. How long does it take for the invention patent to be actually examined and authorized? As short as half a year (one review opinion and reply), as long as several years (four or five review opinions and replies). What is the examination and authorization process of invention patents? China's patent law stipulates that the application for a patent for invention shall be subject to the system of early publication and request examination. The complete examination procedure of an application for a patent for invention includes three stages: preliminary examination, substantive examination and patent grant. An application for a patent for invention must go through these three stages before it can be approved. The preliminary examination stage includes accepting patent applications, collecting patent fees, examining classification and obvious defects, examining formats and publishing patent applications. The substantive examination stage includes the start of substantive examination procedure, the verification of application documents, the preparation and retrieval of substantive examination, the substantive examination and the issuance of the first notice of examination opinions, the applicant's reply and modification, and the examiner's continued examination. The examiner issued the notice of granting patent right on behalf of China National Intellectual Property Administration. The authorization stage includes China National Intellectual Property Administration's two authorization registration notices, applicant registration, China National Intellectual Property Administration's authorization decision, patent certificate issuance and registration, and China National Intellectual Property Administration's decision to grant patent right. A few applications may have to go through revocation procedures and/or invalid procedures after being authorized. The applicant must pay attention to all aspects of payment, and reply to China National Intellectual Property Administration's rectification notice in time, so as to facilitate the smooth progress of patent application examination. Of course, the applicant has the right to withdraw his patent application at any time. The technology patent application has been authorized, and the patentee can also give up the patent right. According to the provisions of China's patent law, if China National Intellectual Property Administration meets the requirements of the patent law after preliminary examination, it will be published 18 months from the date of filing. Therefore, an application for a patent for invention is generally published within 18 months from the date of filing. Because the patent bulletin is published regularly, and the layout of the bulletin is limited, especially the number of patent applications in China is increasing year by year, and the number of examiners in China National Intellectual Property Administration is limited, and there are reasons in the review process, this work may sometimes be postponed.
