According to the provisions of China's patent law, there are three kinds of inventions that can be protected by patents: invention patents, utility model patents and design patents, of which invention patents are the most important.
All patents must be applied to China National Intellectual Property Administration, and only after they are passed will there be a patent certificate issued by China National Intellectual Property Administration, which is understandable from another angle. As long as there is a patent certificate from China National Intellectual Property Administration, it can be said that it has obtained the national patent certification. There is no difference between national patents and regional patents.
