Cooperation with large intellectual property companies usually involves signing confidentiality agreements.
I suggest that you can examine whether an intellectual property company is qualified and formal through the following conditions:
1. Check whether the agency has the corresponding agency qualification. Patent agency qualification, trademark agency qualification, foreign-related patent agency
Science qualification. The agency qualification can be inquired through the website of China National Intellectual Property Administration.
2. Investigate the achievements of clients and patents served by the agency, focusing on the authorization rate of invention patents.
3. Investigating the number of patent agents in the agency, it is found that the agency with more than 20 agents has a medium scale and relatively stable business ability.
