How to inquire patent information of patent number? Is it fake if it is not found?

China National Intellectual Property Administration has a special patent search space on its website. You can see it by entering the application number. At the same time, the status shows: authorized, under review, no right. Under review means that there is no authorization, and no right means no patent right. Related websites are soopat. It is best to contact the patentee directly or check the information about the transfer of Qianyan patent. If you can't find it, it may be fake or it may not be made public. Patent application and disclosure will take some time. After reading your patent number, 20 1020629448.7 is a utility model patent, and I found that all of them were applied at 10. It stands to reason that it should be made public after such a long time, especially the utility model and design patents are suspicious, so they are probably fake.
