As the prices of laser cutting head, laser, laser cutting control system and other core components upstream of laser cutting equipment continue to decline, and the enterprise's technical strength, brand strength and marketing strength continue to improve, the market penetration of laser cutting equipment continues to increase, and the application field continues to expand. In addition, laser cutting is gradually replacing traditional products such as punches, shearing machines, and shearing machines in metal forming machines, The laser cutting equipment industry ushers in a period of rapid development. From 2011 to 2015, patent applications for key technologies of laser cutting in the world increased rapidly and the annual growth rate increased significantly. This stage is mainly due to the fact that the laser cutting market entered the recovery stage after the impact of the global economic crisis, showing a stable and high growth trend. With the development of recent years, the key technology of laser cutting has entered another period of rapid growth.
China's patents related to key technologies of laser cutting have shown explosive growth since 2015 and are in a continuous growth trend. The total number of patent applications filed by Chinese applicants in China occupies a dominant position, accounting for 88% of the total number of applications filed by Chinese applicants, 12% of the total number of patents filed by foreign applicants, and the patent validity of domestic applicants is higher than that of foreign applicants. Foreign applicants still maintain their patent layout in China, and Japan, the United States and Germany are active in China. Among them, Japanese applicants have the largest number of applications in China, accounting for 7%. The overall risk of domestic innovation subjects applying for patents in China is small.
