Can Baidu retrieve any patents that have been successfully declared?

If you can't find it on Baidu, go to the website of the Intellectual Property Office to find a link, or there are links on the homepage of some agency websites, you can go to Kaidong's intellectual property homepage.

The appearance patent and utility model patent can only be searched on the website after the patent office has issued a certificate and announced it. Invention patents can be found after preliminary examination and publication. However, it will take some time from the issuance of paper documents to the online system.
