There are three kinds of patents: utility model, invention and appearance modeling. What kind of person do you think you are? Where there is a China patent network, there will also be local patent offices. The patent application should be written well, and the money should be paid when applying. Go online and Baidu.
But some things can be patented, such as the formula of Coca-Cola, which is a trade secret.
And it should be noted that in China, some things don't have to be patented, but they can also make money, and some things can't make money if they are patented.
I hope it helps you.
