Can the patent be renewed?

China's patent law stipulates that a patent has a certain patent term, and once the patent term expires, the patent will be invalid directly. There are three kinds of patents in China, one is an invention patent with a patent term of 20 years. The other two patent applications are utility model patent and appearance patent, and the patent period is 10 year. One of the characteristics of patents is that they cannot be renewed like trademarks;

Then why can't the patent be renewed? One is the national patent law, and the other is that if the patent application is renewed, all patented technologies can be permanently licensed, which is not conducive to patent implementation. The patentee needs to stand on the shoulders of giants to apply for patents. Therefore, if the patent is reused, it is equivalent to infringement, and if the patent is not renewed, it can also promote the patentee's innovative consciousness.

It is not impossible for a patent to be postponed for a period of time, but generally it will be postponed for one or two months at most, and the specific situation can be submitted to the Intellectual Property Office. If the patentee doesn't know how to operate, he can consult a professional organization. Of course, patents cannot be renewed all the time, and there may actually be new patented technologies to replace them beyond 12 years; Therefore, patents need to develop their own patented technologies, and it is possible to develop new patented technologies.
