Hello:
There are two stages in the invention patent application, one is the preliminary examination and the other is the actual examination. The disclosure specification of the invention patent application is the description during the preliminary examination, while the publication specification of the invention patent application is the specification that has passed the preliminary examination, and the specification during the actual examination is not authorized. What needs to be authorized is the "Invention Patent Specification", which can also be downloaded from the website of the State Intellectual Property Office.
Hope the answer is helpful to you.
