In the examination stage of patent application, what is examined is not the physical object, but the patent application documents, that is; The written materials and technical drawings are audited, so as long as your technical scheme is basically completed and theoretically established, you can apply for a patent and have the opportunity to authorize it.
If there is something in kind, it may be more helpful for the promotion of patents, hehe.
In addition, I remind you that if you want to put this idea into practice and put it on the market, please entrust the relevant agency to help you write the patent application documents.
