So for what you said, if aliens teach you, there is no problem. Because inventions require practicality, novelty and creativity. And you are required to have a detailed technical plan and feasible technical drawings, even physical objects. So if you want to apply for an invention patent, your flying saucer must be a product that you can produce. Since you can produce it naturally, the document you submitted is feasible and its principles can be embodied.
Lawyer Liu of Beijing * * * Teng Intellectual Property Agency Co., Ltd. suggested that invention is a review that reflects technical characteristics, mainly examining the technology itself, not its function. If I want to build a spaceship out of thin air, I think it can take me to America in 1 second, but this realization plan is empty. This kind cannot be patented. Or we imagine replacing oil with something cheap and ubiquitous, but how to realize it is empty, which is not the essence of patent. Patents protect technology, not imaginary functional descriptions.
