How do middle school students apply for national patents?

It depends on what kind of patent you are applying for (patents are divided into invention, utility model and appearance). What is needed are requests, instructions and drawings. If you haven't done it before, it's not easy to write it yourself You can go to a patent agency (the cost is not low), and students can apply for relief. The application fee can be reduced by 85%, that is, as long as you pay 15%
