From the definition of invention and utility model in the Detailed Rules for the Implementation of the Patent Law, invention refers to a new technical scheme for a product, a method or its improvement, and utility model refers to a new practical technical scheme for the shape, structure or combination of a product. It can be seen that the invention can protect more subjects than the utility model, and the utility model patent can only protect the structural aspects (including the layer structure), but not the methods and materials, while the invention patent can protect the methods and materials in addition to the structural aspects. Both design and utility model involve the shape of the product.
