Before thinking about this, you still have to wait until you understand all the laws of physics before drawing any conclusions. Also, I don’t understand whether you just fantasized or whether you really “invented” your so-called perpetual motion machine. Since you asked the question, I suggest that you check two points carefully. 1. Whether there is any loss of energy during operation, and 2. whether the functions are obtained. There is currently a clock in the world that can run forever, but it is driven by changes in external air pressure and is not a true perpetual motion machine. In fact, conservation of energy was originally a hypothesis that explored the failure of perpetual motion machines. If you really invent it, it will basically subvert modern physics. It is currently a more technical technology than a time machine. Then why don't you do research? If you really have that ability, it doesn't matter if you don't have a patent. Wouldn't it be better to contribute to mankind? Besides, once your machine is proven to be effective, all institutions in the world will immediately Modify the system and give you a patent. After all, it is an innovation that has never been done before or since. Let me give you an example. Madame Curie did not apply for a patent for refining radium technology at that time, but did she need any protection?
