How long does it take to authorize the patent after it is published?

Legal Analysis: According to the Patent Law, there are three kinds of patent applications that domestic and foreign applicants can file with China Patent Office: invention patent, utility model patent and design patent application. Inventions and utility models are applications for technical improvement, and applications for invention patents can protect product and method inventions; The application for a patent for utility model does not protect the method invention, but only protects the product and the improvement of its structure; An application for a patent for design only protects the appearance, shape, pattern or their combination and the combination with color of the product. Invention patents are granted for a long time, usually three to five years, but the granted patents are highly stable due to the need for substantive examination procedures; Patents for utility models and designs do not need to go through substantive examination procedures, so they can be granted quickly. Generally speaking, the utility model can be authorized within six to twelve months from the date of application, and the design can be authorized within about six months from the date of application.
