There are three kinds of patents: invention, utility model and design.
An invention patent refers to a new technical scheme proposed for a product, method or its improvement. An invention that can be patented can be a product invention or a method invention.
A patent for utility model refers to a new technical scheme for the shape, structure or combination of products, which is suitable for practical use. An application for a patent for utility model must be a product patent application.
A new design made by a design patent for the shape, pattern, color or their combination of products, which is aesthetic and suitable for industrial application. The new design can be a graphic design of lines, patterns or colors, or a three-dimensional modeling of the product.
Technical patents refer to patents related to the working principle or structure of products, including invention patents and utility model patents.
Patents are generally documents issued by government agencies or regional organizations representing several countries according to their applications. This kind of document records the contents of the invention and creation, and in a certain period of time, it has produced such a legal state that the patented invention and creation can only be implemented by others with the permission of the patentee. In China, there are three kinds of patents: inventions, utility models and designs.
The patent system aims to protect technology from infringement of exclusive rights, and any subject other than the obligee can only obtain the right to use the patent through the authorization of the patentee. With the continuous improvement of the legal system, the use of patents presents a diversified trend, and patents are invalid, revoked and expired. Only by fully understanding such a legal system can we make full use of patent resources and realize more economic value for enterprises.
