How do Chengdu college students apply for patents? What is the national policy?

You can go to the local (municipal or above) local patent acceptance department for consultation or go to the local patent agency for consultation! However, the claims in the patent application are very strict with the text format, so it is not recommended to apply for it yourself. You'd better find a professional intermediary! ~ and the cost of applying by yourself is much more expensive than that of finding a professional institution!
