What products can apply for utility model patents?

Hello, the utility model mentioned in the Patent Law refers to a new practical technical scheme for the shape, structure or combination of products. The difference between utility model and invention lies in: firstly, utility model is limited to products with a certain shape, and cannot be a method or a product without a fixed shape; Second, the creativity of the utility model is not too high, but it is 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 the product shape can be the technical scheme proposed for the three-dimensional shape of the product, such as the improvement of the cam shape and the cutter shape; It can also be a technical proposal for the two-dimensional shape of the product, such as the improvement of the cross-sectional shape of the profile.

the structure of a product refers to the arrangement, organization and interrelation of various components of the product. The structure of the product can be mechanical structure or circuit structure. Mechanical structure refers to the relative position relationship, connection relationship and necessary mechanical cooperation relationship of components that make up a product, and circuit structure refers to the definite 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.

I hope I can help you to adopt it.
