Where is a good place to apply for a patent? Need reliability! ?

First of all, we must choose an agency with agency qualification, at least it will not be a black agent, and it has the most basic guarantee. It can be found through national or provincial intellectual property offices. Secondly, priority can be given to well-known agency companies in the industry. You can enter the name of the agency on the patent search website and see the cases it has represented, including the quantity and quality of customers (famous enterprises). Third, and most importantly, communicate with the agent face to face, ask yourself what you don't know about the patent, communicate with the technology appropriately, and judge the level of the agent through communication, including business ability and technical understanding ability. Actually, it's better to choose an agent than an agent. There are high-level and low-level institutions in the same place, so communication with technicians is very important.
