Invention refers to a new technical scheme proposed for a product, method or its improvement. An invention must be a technical scheme, the result of the inventor's application and combination of natural laws in a specific technical field, not the natural laws themselves, so scientific discovery does not belong to the category of invention. At the same time, inventions are usually intellectual achievements in the natural sciences, and achievements in the fields of literature, art and social sciences cannot constitute inventions in the sense of patent law.
