Method 1: Distinguish from the application number
The application number of China is similar to this: 20 13 10688347.5. Among them, 20 13 is the year; The fifth digit 1 stands for invention; 06888347 indicates the serial number of the current year; The last number .5 is the check code. So we can judge the type of patent from the fifth place of the application number.
Method 2: Distinguish by document number.
The text number is the number of public text and announcement text. Types can also be easily distinguished from the document numbers of China patent documents. CN 1 from invention; The beginning of CN2 is utility model; CN3 starts from design; At the end of ABC, it is invention; UYZ ends with utility model; Finally, DS is design.
Method 3: distinguish from the text content.
This method is very simple. In fact, every text of China patent application will clearly indicate its invention type. Just look at the contents after the brackets 12.
1, invention patent
Invention as mentioned in the patent law refers to a new technical scheme proposed for a product, method or its improvement. Invention is a technical scheme that people use the laws of nature to solve various problems in production and life. Inventions can be divided into product inventions and method inventions. Product invention is about the invention of new products or new substances.
Method invention refers to the invention of methods and steps to solve specific technical problems. If the application for a patent for invention meets the requirements stipulated in the Patent Law after examination by China National Intellectual Property Administration, the patent right for invention shall be granted.
2. Patent for utility model
The term "utility model" as mentioned in the patent law refers to a new technical scheme suitable for practical use for the shape, structure or combination of products. The difference between utility model and invention: first, utility model is limited to products with certain shapes, and it cannot be methods, such as production methods, test methods, treatment methods and application methods; Second, the utility model is not too creative, but it is very practical.
In view of the latter feature, people generally call it an invention. If the application for a patent for utility model meets the requirements stipulated in the Patent Law after examination by China National Intellectual Property Administration, the patent right for utility model shall be granted.
3. Design patents
The term "design" as mentioned in the patent law refers to a new design that is aesthetically pleasing and suitable for industrial application, which is made by the shape, pattern or combination of products and the combination of color and shape and pattern. Both design and utility model can involve the shape of the product. The difference is that the utility model is a technical scheme, and the shape involved is related to the technical effect and function of the product.
Appearance design is a design scheme, and the modeling involved is related to the aesthetic feeling of the product. Where an application for a patent for design meets the requirements stipulated in the Patent Law after examination by China National Intellectual Property Administration, the patent right for design shall be granted.
