How to search for useful patents to go to patents that do not have the right to others

First of all, you need to understand what it means to invalidate someone else's patent, and what are the grounds for invalidating someone else's patent. This is the most basic. If you don't know, you can take a general look at the Patent Law and the Patent Law Implementation Rules.

Then, if you look at the legal status of other people's patents, if they are invalid, you basically don't need to invalidate them anymore. For patents that are still valid, take a look at the application date, if they are about to expire, there is no need to invalidate them, and wait for them to expire and enter the public domain. If it is necessary to invalidate a patent that is currently in force, then carefully study the technical content of another person's patent, see if there are any defects in the form of his document, and then search for relevant things for the technical content to see if it has been disclosed before the filing date, and if the document is defective, etc.

Finally, if you are not very knowledgeable about patents, it is recommended to entrust a special ** agency (most of them are called intellectual property ******) to help you do invalidation, because this work is a very professional work, and a little carelessness may affect the final result (even in different years, the reasons and evidence for invalidating other people's patents may be different).

If you have an interest in his patent, you can do it, and if it doesn't, you will offend people if you do it. If you want to invalidate someone else's patent, it is very simple, file it with the patent office, send a request for invalidation with your statement of reasons, and ** to the patent office****.

First open it, enter: "State Intellectual Property Office", as shown in the figure below, there is a patent query opened:

Finally, enter the patent number, especially emphasized: the patent number, the name of the inventor, and the person who applies for a good round posture must fill in one to check the cavity and get it, and then enter the verification code and click to query.
