How do we identify the qualifications, strength and services of intellectual property agencies, and so on?

If it is a trademark, you can log on to China Trademark Network, which has the detailed information of the registered agency. If it is a patent, you can ask the agency to show the practicing certificate issued by China National Intellectual Property Administration and the relevant business license. You can consider the following aspects: 1. Check the agency website to understand the basic situation. 2. Check whether there are any cases and cases of intellectual property cooperation between government agencies. For example, related lectures on intellectual property rights, etc. 3. Through the retrieval system in China National Intellectual Property Administration, check the case information of cooperation between agencies and large local enterprises. There are more cooperative enterprises, which also shows that the strength of the agency is stronger. 4. If conditions permit, you can go to the agency for on-the-spot investigation, on-site communication and exchange, and personally feel whether it is professional or not.
