How to tell whether this patent has been authorized by China patent number? Please give an example, thank you!

You can't judge whether an application is authorized only by the number, because as long as the application is submitted and the documents are qualified, the application number will always exist. After the patent application is granted, add "ZL" before the application number as the authorization number. Therefore, it is suggested that if you just want to know whether it is authorized, you only need to search the legal status of the patent application corresponding to this number on the website of China National Intellectual Property Administration. If it involves patent transfer, licensing and other matters, you'd better ask the Patent Office to issue a copy of the register to confirm whether it is authorized or not and whether the patent is still valid.
