There are two stages in the application for a patent for invention, one is preliminary examination, and the other is actual examination. The public specification of an application for a patent for invention is the specification at the time of preliminary examination, while the public specification of a patent for invention is the specification at the time of preliminary examination and actual examination, and there is no authorization. What needs authorization is the "Invention Patent Description", which can also be downloaded from China National Intellectual Property Administration's website.
