What is the object of patent law protection?

Patent law is a kind of law to protect patents promulgated in China. The object protected by patent law is also the object of patent right, which refers to the invention and creation that should be granted patent right according to law. So what is the object of patent law protection? The object invention protected by the latest patent law 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. Utility model refers to a new technical scheme suitable for practical use for the shape, structure or combination of products. The utility model patent only protects the product. Products should be manufactured by industrial methods and occupy a certain space. All related methods (including the use of products) and natural objects that have not been artificially manufactured are not protected by utility model patents. The above methods include manufacturing methods, using methods, communication methods, processing methods, computer programs and using products for specific purposes. For example, the manufacturing method of a gear, the dust removal method in the workshop, the data processing method, the naturally occurring rain flower stone and so on. Can't be protected by utility model patent. Appearance design, also known as industrial product appearance design, refers to a new design with aesthetic feeling and suitable for industrial application based on the shape, pattern or their combination of products and the combination of color, shape and pattern. The carrier of design must be the product. Product refers to any article produced by industrial methods. Handicrafts, agricultural products, livestock products and natural objects that cannot be produced repeatedly cannot be used as the carrier of design. Usually, the color of a product can't form a design independently unless the color change of the product itself has formed a pattern. The combinations that can constitute the design are: the shape of the product; The style of the product; The shape and pattern of the product; The shape and color of the product; Patterns and colors of products; The shape, pattern and color of the product. There are three kinds of objects protected by patent law, namely, invention patent refers to a new technical scheme proposed for a product, method or its improvement; The second kind refers to the utility model patent, which is a new practical technical scheme for the shape, structure or combination of products, and it only protects products; The third is design patent, which can also be called industrial design. It is a new design with aesthetic feeling and suitable for industrial application based on the shape, pattern or combination of products and the combination of color and shape and pattern.
