How long is the duration of the invention patent right?

The term of patent right refers to the legal term and termination time of patent right. If the patent right has not been terminated for other reasons since the announcement of the authorization of the patent right, the patent right shall be terminated on the expiration of the patent right period. According to the provisions of the patent law, the term of invention patent is 20 years; The term of utility model patent and design patent is 10 year, counting from the date of application.

In view of the fact that patent right is an intangible property right, which is different from ordinary property right, there is no problem of natural termination of rights due to the disappearance of objects. Therefore, the patent laws of various countries stipulate the term of patent right for the following reasons:

(1) The patented technology itself has the characteristics of gradually losing its property value with the passage of time and the improvement of technical level;

(2) The long-term monopoly of patent rights is not conducive to the scientific and technological progress of the whole society and the development of the industry.

There are three kinds of patent applications: invention, utility model and design. You may apply for a patent for invention for a new technical scheme proposed for a product, method or improvement; You can apply for a patent for utility model for a new technical scheme that is suitable for practical use according to the shape, structure or combination of products; A new design that is aesthetically pleasing and suitable for industrial application is made according to the shape, pattern or combination of them, and the combination of color and shape and pattern, and can apply for a patent for design.

Patent application is a legal procedure. If the inventor applying for a patent wants to obtain a patent right quickly and safely and obtain legal protection, he can entrust a patent agent of the Patent Office to provide you with legal and technical assistance. Once the inventor has established an agency relationship with the patent agent, the patent agent is your technical consultant and patent lawyer.

After establishing an agency relationship with a patent agent, the inventor shall provide detailed technical information necessary for writing patent documents according to the requirements of the agent; Detailed technical data include the purpose of invention and creation, the comparison between old and new technologies, the main technical features, the specific scheme to realize the purpose of invention and creation, and the attached drawings that can explain the purpose of invention and creation.

If the inventor can't draw drawings or provide necessary detailed technical data, he can directly dictate to the patent agent, and the patent agent can complete the whole process of patent application for you according to the inventor's invention intention until the patent right is obtained.
