How long is the protection period of the invention patent? What is the significance of the protection period? Because patents are different, the duration of patent protection is also different. Patents in China are divided into utility model patents, design patents and invention patents. The protection period of design and utility model patents is 15 years, but the protection period of invention patents is different. The protection period of an invention patent is slightly longer, and the protection period of an invention patent is 20 years. So it is necessary to tell you that the gold content of invention patents will be relatively higher than the first two patents, but not necessarily higher.

You can't think that a patent is supreme just because a certain condition is superior. The value of a patent needs to be combined with the current patent market. Some invention patents have no social value, so they are not good patents, but some utility model patents or appearance patents can play an important role, which greatly reflects the practicality of patents. Some patentees will ask why there should be a patent protection period for inventions. Patented technology is the product of wisdom gained through hard work. Why can't you keep it for yourself and always use it? We can imagine that once a patent is used unconditionally, it will form an authoritarian patent, which will bring a burden to society if it is not used well; This can show that the state has made compulsory licensing for some patents and prohibited profiteering from patents. Leaving aside the long-term patent autocracy during the protection period of invention patent, if a patent always gains benefits, it will have a negative impact on the patentee's spirit of invention creation, and the patentee will stagnate and enjoy the harvest brought by the patent all the time, which will greatly hit the patentee's innovation consciousness; Therefore, the provisions of the state on the protection period of invention patents are reasonable. A patent can be used for more than ten or twenty years, which is a sure profit.
