How to inquire the patent number of a company's patent application?

China National Intellectual Property Administration website views the review information of all patent applications submitted through electronic application. If you are not an electronic registered user, or you are not looking for your own patent, you can use the Wisdom Bud patent search platform to check the case status of patent information after the application number. Note: Public inquiry can only find the published patent application information, which is better for the published invention application. Utility models and designs cannot be found without authorization.
