Patent public welfare

First of all, there should be no problem with your invention application. Secondly, whether you can get authorization depends on what patent you are applying for. It is easy to get authorization to apply for a patent for utility model, but it is difficult to apply for a patent for invention, which requires substantive examination. As for compulsory promotion, I think it is almost impossible. In the 25 years since the implementation of the patent system in China, there are almost no such examples. Therefore, whether to apply or not, you have to make up your own mind.
