How about actually looking at a company? It needs to be investigated from many aspects. For example, does he not have a formal business license? For example, what is its size? What about his staff? What is the scope of business? Efficiency? Service level? Wait for a series of questions. As far as I know, Mingyi Intellectual Property is quite good. Their personnel are up to standard, their scale is large, and their mechanism is relatively complete. More importantly, they have their own intellectual property agency and are well-known in the country. You can also check it on the bureau’s website, so it’s relatively formal. Many intellectual property companies still focus on telemarketing, so it is inevitable to make phone calls. I have been to the company before and they are indeed very good. It is said that Mingyi is the best in the northwest!
