There are no famous patents, and there are three types of patents stipulated in China's patent law: invention patents, utility model patents and design patents. An invention refers to a new technical scheme proposed for a product, method or its improvement. Method invention divided into product invention and technical scheme. Product invention refers to all inventions that appear in tangible form, that is, using objects to express their inventions, such as machines, equipment, instruments, supplies, etc. Method invention refers to the invention that the technical scheme provided by the inventor is aimed at a certain substance to produce new technical effects. Methods The technical scheme of the invention was expressed by operation mode and technological process. Utility model refers to a new practical technical scheme for the shape, structure or combination of products. The utility model patent only protects products with certain shapes, and products and methods without fixed shapes and designs featuring simple plane patterns are not protected here. Because utility model patents and applications have the characteristics of no substantive examination, short approval period and low cost, the number of applications for this type of patents accounts for 2/3 of the total number of patent applications. R Appearance design refers to a new design with aesthetic feeling and suitable for industrial application, that is, the style of the product. It also includes designs featuring simple plane patterns.
