1. You can find information about patents, including published and authorized patents, on the website of China National Intellectual Property Administration. If you can't find it, it is likely that the patent has just been applied and is still in the review stage, and it has not yet reached the publication stage. What is not found so far is not necessarily a fake patent.
2. The published patent may not be finally authorized. Because after the invention patent is published, it still needs substantive examination to authorize, but the intermediate process takes three years. Utility models and designs can be authorized as long as they pass the preliminary examination, which is faster.
3. The authorized patent may also be invalid. Whether the patent has value or market needs to be tested. China National Intellectual Property Administration is not responsible for investigating whether the patent market has any prospects.
4. Regarding the confidential patent, for the application of confidential patent, the authorization announcement only publishes the patent classification number, patent number, application date and authorization date. But the details have not been announced. Even confidential patents can be found, don't worry.
