When is the year when the patent right was granted, the date when the authorization notice was issued or the date when the authorization announcement was made?

The patent authorization date is the patent authorization announcement date. Only the notice of authorization does not confirm that the patent has been authorized, because it is possible that the patent applicant will not go through the formalities after receiving the notice, so the patent will have no patent right. However, the term of protection of a patent is not counted from the date of authorization, but from the date of actual application. For example, your application was submitted on June 65438+1 October12008. Today's authorization announcement, the annual fee has been paid since June 65438+1 October12008, because your patent has been protected since that day.
