Is there a patent application only for authorized invention patents?

The authorization specification of the invention patent is the final version of the patent specification. After an application for a patent for invention has been submitted and passed the preliminary examination, it will generally be made public at the end of 18 months from the date of application (if the patent applicant applies, it can also be made public in advance), and then the published version of the specification is the patent application disclosure specification. Generally speaking, it is the original document submitted by the applicant of a patent application. After the publication of the invention patent, it will enter the substantive examination procedure within 3 years from the date of application, and the examiner will search at this stage to examine the novelty and creativity of the patent application, and may issue a notice of examination opinions. The applicant needs to reply or modify the opinions according to the contents pointed out in the notice of examination opinions, so as to overcome the defects of originality or other aspects. In this process, the specification of a patent application may be modified once or more, and finally it can pass the examination. The authorized version is the application authorization specification. Therefore, there may be differences between the contents of the patent application disclosure specification and the authorization specification, but according to Article 33 of the Patent Law, "Article 33 An applicant may modify his patent application documents, but the modification of the patent application documents for inventions and utility models shall not exceed the scope recorded in the original specification and claims, and the modification of the patent application documents for designs shall not exceed the scope shown in the original pictures or photographs." That is to say, there are restrictions on the modification of the application documents, so compared with the application disclosure specification, the claims in the authorization specification may be quite different, but the changes in the specification are generally not too big. What materials should I prepare to apply for a national invention patent? 1. Claim: The description of the claimed invention refers to the substantive technical features of the invention. 2.
