Specifically, in the sub-technical branch of the field of precision manufacturing materials in recent ten years, the number of patents for advanced metal materials, advanced inorganic nonmetal materials, advanced polymer materials and advanced composite materials in recent ten years were 1 18497, 57543, 5 1254 and 27636, respectively, and the patent activity in recent ten years was 84.
By analyzing the number of patent applications and patent activity of China's sub-technology branches in the field of cutting-edge new materials in recent ten years, we can know that the patent activity in the field of low-dimensional nano-materials is the highest in recent ten years, reaching 95.93%, which is the key direction of patent layout in the field of cutting-edge new materials in China.
Specifically, in the sub-technology branches of frontier new fields in recent ten years, the number of patent layouts of frontier new materials such as new energy materials, biomedical materials, low-dimensional and nano-materials in recent ten years is 447 19, 79027, 48342 and 1 respectively.
It can be seen that the key direction of patent layout in the field of electronic information materials in China is new display materials; China's patent layout in the field of precision manufacturing materials focuses on advanced composite materials; China's patent layout in the field of cutting-edge new materials focuses on low-dimensional and nano-materials.
