my country protects inventions and three types of inventions. An invention refers to a new technical solution proposed for a product, method or improvement thereof; a utility model refers to a new technical solution proposed for a product's shape, structure or their combination that is suitable for practical use; and an appearance design refers to a modification of the shape of a product. , patterns, colors or their combinations to create new designs that are aesthetically pleasing and suitable for industrial application. It can be seen that inventions and creations protected by patent law have specific meanings. Invention and utility model patents only protect inventions and creations in the technical field, that is, they only protect technical solutions. Pure scientific theories, teaching methods, computer methods, artificial rules, etc. cannot be patented. The Patent Law stipulates that patents can be divided into two categories: product invention patents and process invention patents. Products refer to all inventions that appear in material form, such as the invention of machines, instruments, tools and their parts, and the invention of new materials and new substances. Methods refer to all inventions in the form of procedures and processes, such as product manufacturing and processing techniques, material testing and assay methods, and inventions on how to use products. Utility model patents do not protect method inventions; their protection objects are limited to part of the product invention, that is, products with a certain shape or structure. The appearance design protects the appearance characteristics of the product. This appearance feature must be embodied by a specific product, and products with this appearance feature can be produced and copied using industrial methods. The characteristic of this appearance can be the main shape of the product, the surface pattern of the product, or a combination of the two, but it cannot be a pattern or graphic design that is divorced from the specific product.
