How to apply for a patent with a good idea?

First, determine whether the patent you want to apply for is an invention, utility model or design. Search whether any enterprises or individuals have applied for the same patented technology before, and then submit different materials, technical disclosure books and schematic diagrams for different patents. The core protection scope of products should be clear, which involves very professional knowledge. Generally speaking, in China, you need to find a qualified institution to help you submit your application, but you can't get it yourself.
