Patent type

There are three types of patents in China.

1. An invention patent refers to a new technical scheme proposed for a product, method or its improvement. Inventions that can be patented can be products, methods, processes, formulas, etc. For the invention patent application, China implements the substantive examination system, which takes a long time, generally taking 2-4 years. Once authorized, the protection period is 20 years.

2. Patent for utility model: refers to a new technical scheme for the shape, structure or combination of products, which is suitable for practical use. The application for a patent for utility model must be a product with a certain spatial structure or circuit structure, and the method, process and formula cannot be applied for a patent for utility model; For the application for a patent for utility model, China implements a formal examination system without substantive examination. The review period is generally about one year, and once authorized, the protection period is 10 year.

3. Design patent: a new design that is aesthetically pleasing and suitable for industrial application for the shape, pattern, color or combination of products. The new design can be a graphic design of lines, patterns or colors, or a three-dimensional modeling of the product. The design does not protect some functions of the internal structure of the product. China implements a formal examination system for design patents, and does not conduct substantive examination. The general review period is 6-8 months, and once authorized, the protection period is 10 year.

Therefore, the applicant should provide sufficient information and actively cooperate with the patent agent to write documents. The following are the materials required for several common types of patent applications:
