How to search for new drug patents? I designed a work to participate in the innovation competition, saying that I wanted to search for patents. What should I do?

How to search for patents: Log on to Baten Patent Inquiry Network and enter the key words of the patent you want to search for or the technical key words contained in it. Then click search, and you can find out whether there are duplicate patented technologies. If you want to check foreign patents, choose foreign patents. If it is not enough, you should input the corresponding foreign language.
