Local snacks applied to become a famous snack.

There are three kinds of patents in China: invention patent, utility model patent and design patent local snacks. The first two patents are impossible to apply for because they are well known. But if you design a certain appearance of snacks, it is ok to apply for a design patent. The patent application process, requirements and fees can be found on the website of China National Intellectual Property Administration. If you are not clear, you'd better ask a patent agency for help. The list of agencies can also be found on this website.
