What's the difference between invention patent and utility model patent?

China has both invention patents and utility model patents. Some people may think that utility model is not a kind of invention patent, but actually two different patents. In essence, these two patents are new creations in science and technology, but they are also very different. Today we will talk about the difference between utility model patent and invention patent. What's the difference between invention patent and utility model patent? Invention patent mainly refers to creation, that is, a new technical scheme proposed for a product, method or its improvement. (1) creation is a new technical scheme. Technical scheme refers to the detailed idea of using natural laws to deal with a specific technical problem in human consumption and life. It is a plan to make use of the laws of nature to produce certain effects. A technical plan usually consists of several technical features. For example, the technical features of the product technical scheme can be parts, components, data, appliances, equipment, installation shape, structure, composition, size, etc. The technical features of the technical scheme can be process, steps, flow, time, temperature, pressure, equipment and tools used, etc. The interrelation between various technical features is also a technical feature. (2) Inventions are divided into product creation and method creation. Product creation includes all the creations made by people. Method creation includes all methods of applying natural laws, which can be divided into manufacturing methods and operating methods, such as the creation of processing methods, manufacturing methods, testing methods or product application methods. The creation of patent law maintenance can also be the improvement of existing products or methods. The vast majority of creations are improvements to existing technologies, such as stopping the new combination of certain technical features and stopping the new selection of certain technical features. As long as these combinations or choices produce new technical effects, they can obtain patent protection. The "applicable new style" as mentioned in the patent for utility model refers to a new practical technical scheme for the shape, structure or separation of products. The similarity between new application and creation is that new application must also be a technical solution, not a general concept or theoretical expression. The difference between new application and creation lies in: first, new application is limited to products with certain shapes, and it cannot be methods, such as consumption method, experiment method, disposal method and application method, nor can it be products without fixed shapes, such as drugs, chemicals and cement; Second, the application requirements of the new invention are not too high, but the applicability is strong.
