When we apply for a patent, we need to search related patents that have been published, and we need to know whether these patents are authorized to judge the feasibility of our patent application. At the same time, when conducting a research, we also need to pay attention to the patents and authorizations of some related research around us.
First, go to the official website of China National Intellectual Property Administration and click "Patent Search and Query" in the menu bar above. After entering, click "China Patent Inquiry System" again.
