Can a patent that has passed the preliminary examination be authorized?

Invention patent (there is no real trial stage for utility model and appearance, and it can be authorized after preliminary examination, that is, it can be licensed). There are several stages: acceptance, preliminary examination, actual examination and authorization. The preliminary examination is only a formal examination of your patent by the Intellectual Property Office, that is, a superficial examination. The real test is the real trial (substantive examination) of the patent.

Whether your patent can pass or not depends mainly on how much you know about your technology. If the patent does solve some problems, the technology is relatively advanced, and the packaging of professional institutions, there is basically no problem with authorization, but compared with practicality and appearance, it takes about 2 years to apply for invention.

Therefore, the preliminary examination is only a stage of the invention patent, which does not mean whether it can be authorized in the end!
