Can high-value patents be applied through patent agencies? Urgent!

China Council for the Promotion of International Trade, Beijing Port College, Sanyou, etc. They are all good agencies, and they are exposed to thousands of domestic and foreign patents every day. From application writing to authorization, the quality is very high. Personally, I think that a person without any patent experience is not suitable for his own agency application, and it is easy to get authorization because of some procedural or communication problems. Even if it is done by an agency, it is necessary to fully communicate with the agent to understand the actual scope of protection (this is the key). In addition, we can hide the technical know-how (based on implementation) by vague technical means and expanding the parameter range to prevent leakage.
