China's patent law stipulates that the patent right for invention is valid for ten years, right?

The patent law of our country stipulates that the validity period of the invention patent right is ten years, which is correct. China's patent law stipulates that an invention must be a creative technical scheme in order to achieve "novelty" and "practicality". Patent right is the exclusive right of the inventor or his successor to the invention. The authorization period of the invention patent right is 10 year, counting from the date of authorization. This means that anyone must pay royalties to the patentee before the patent expires. Obtaining the invention patent right requires substantive examination, which is quite difficult. Common examination questions are novelty, creativity, extended rationality and so on. The scope of patent protection includes the supervision of commercial activities such as the production and sale of inventions, and the infringer must bear the economic losses caused by the infringement.
