What are the objects protected by patent law?

(1) Invention refers to a new technical scheme proposed for a product, method or its improvement. 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. (2) Utility model Utility model refers to a new technical scheme that is suitable for practical use for the shape, structure or combination of products. The utility model patent only protects the product. The product should be an entity manufactured by industrial methods and occupying a certain space. All related methods (including the use of products) and natural objects that have not been artificially manufactured are not the protected objects of utility model patents. The above methods include manufacturing methods, using methods, communication methods, processing methods, computer programs, and using products for specific purposes. (3) Design Design, also known as industrial product design, refers to a new design that is aesthetically pleasing and suitable for industrial application, based on the shape, pattern or their combination of products and the combination of color and shape and pattern. The carrier of design must be the product.
