Patent application specification? And then what? Approval authorization statement? What is the difference?

What is the difference between the public specification and the authorization specification of a patent application? A: The prospectus is only a preliminary review; The authorization specification has been examined for patentability, and the authorization specification shows that the patent right has been obtained. Is the patent valid without authorization? A: There are many cases where a patent is not authorized, such as the patent application has not entered the substantive examination procedure, the patent application has not been closed in the substantive examination procedure, the patent application has been voluntarily abandoned, the patent application has been rejected, it is being reviewed after being rejected, and the patent application is authorized to wait for the announcement. Therefore, it is uncertain that the authorization statement is invalid without approval. I mean, when I looked it up on the website of the Patent Office, I found that many patents only applied for instructions and did not review the authorization statement. Does this mean that these patents have not passed the examination of the patent office? A: No, there are many situations. Please refer to the above reply. If so, these patents have no legal effect and cannot be used. So why didn't the Patent Office delete all these contents and put them on the website? A: Because after the patent application, if the applicant does not request to withdraw it, all of it will be made public, so the Patent Office cannot delete these contents. Note: Inquiring about the legal status of patents can better explain the situation of these patent applications. You can enter the application number in the legal status retrieval window to get the real status of the patent application.
