What does the utility model patent mean?

The utility model patent in the patent law refers to a new technical scheme suitable for practical use for the shape, structure or combination of products. The structure, shape or combination of structure and shape of any product shall apply for a patent for utility model. The protection period is 10 year. The difference between utility model and invention lies in: first, utility model is limited to products with a certain shape, and it cannot be a method or a product without a fixed shape; Second, the utility model is not too creative, but it is very practical. The shape of a product refers to the definite spatial shape that the product has and can be observed from the outside. The technical scheme proposed for product shape can be the technical scheme proposed for product three-dimensional shape, such as the improvement of cam shape and cutter shape; It can also be a technical scheme of two-dimensional shape of products, such as the improvement of sectional shape of profiles. The structure of a product refers to the arrangement, organization and interrelation of various components of the product. The product structure can be either a mechanical structure or a circuit structure. Mechanical structure refers to the relative position relationship, connection relationship and necessary mechanical cooperation relationship between components that make up a product, and circuit structure refers to the determined connection relationship between components that make up a product. The composite layer can be considered as the structure of the product, and the carburized layer and oxide layer of the product belong to the composite layer structure.
