What are the types of national patents?

Propriety refers to the patent right enjoyed by the patentee for invention-creation, that is, the state grants the inventor or his successor the exclusive right to use his invention-creation within a certain period of time according to law, and the emphasis here is on rights. Patent right is an exclusive right with exclusivity. If a non-patentee wants to use the patented technology of others, he must obtain the authorization or permission of the patentee according to law. Mainly divided into the following categories: invention refers to a new technical scheme proposed for products, methods or their improvement, which mainly embodies novelty, creativity and practicality. Patent inventions are divided into product inventions (such as machines, instruments and equipment, appliances) and method inventions (manufacturing methods). Utility model refers to a new practical technical scheme for the shape, structure or combination of products. The patent for utility model is granted without substantive examination, with simple procedures and low cost. Therefore, small inventions about tangible products such as daily necessities, machinery and electrical appliances are more suitable for applying for utility model patents.
