The legal status of patent authorization and publication is not a single issue, and it needs to be distinguished according to the types of patents. Generally speaking, it takes about four to five months for the patent office to accept the application and finally authorize it, and it takes about four to six months for the utility model patent. It takes about two and a half years for the invention patent to be normal (premise 1. Require early disclosure; 2. The substantive examination fee should be paid in time), except for special circumstances, such as a long time after the medical patent, because it needs some data support such as clinic, so the time has returned to five or six years.
The publication of a patent does not mean authorization. After the invention patent passes the preliminary examination, it will be made public in advance for the speed of issuing certificates. At this time, the patent will also be made public, but it does not mean that you have a patent right, because the substantive examination stage will not pass and the patent right will not be granted in the end.
I hope it helps you.
