Can patent agencies and agents report?

First of all, you should determine whether they are regular patent agencies, that is, go to China National Intellectual Property Administration's website to check whether they are qualified. If they are qualified, they all have the agent registration certificate issued by China National Intellectual Property Administration. If there is a problem with the regular agency, you can complain to the provincial agency association. If they are unqualified, the agency association can't handle it, and they have to go to court to sue.
