Scientific discovery refers to the revelation of unknown substances, phenomena, changing processes, characteristics and laws that exist objectively in nature. Scientific theory is a summary of the understanding of nature and a broader discovery. All belong to the extension of people's understanding. These recognized material phenomena, processes, characteristics and laws are different from the technical scheme to transform the objective world and do not belong to the invention in the sense of patent law. For example, it is found that silver halide has photosensitive properties under illumination, and this discovery cannot be patented, but the photosensitive film manufactured according to this discovery and the manufacturing method of this photosensitive film can be patented. For another example, finding a substance in a previously unknown natural form from nature is just a discovery and cannot be patented.
It should be noted that although invention and discovery are essentially different, they are closely related. Usually many inventions are based on discovery, and then inventions promote discovery. The close relationship between invention and discovery lies in the "practical invention" of chemicals.
The most outstanding performance in the world is that when the special properties of a chemical substance are discovered, the "use invention" of this property is used.
So it came into being.
