With the continuous improvement of energy-saving and environmental protection awareness, LED lamps have been widely used in the field of architectural floodlighting, indicating that the history of human lighting will soon enter the era of a new green light source after incandescent lamps and fluorescent lamps. However, the "Shanghai Semiconductor Lighting Products Technology Roadmap" completed by the Shanghai Academy of Sciences recently shows that local companies currently account for less than 5% of the industry's patents. The semiconductor lighting "patent predators" from overseas are facing Shanghai and even the whole country. The semiconductor lighting industry is formed into a circle.
Research shows that in recent years, multinational companies represented by the three major lighting giants such as General Electric of the United States, Philips of the Netherlands, and Osram of Germany have cooperated with upstream semiconductor companies to build new semiconductor lighting companies, and seized patent highs in China to build a patent encirclement. For example, GE has established a new world-class lighting company in Shanghai. At the same time, the number of patent applications for semiconductor lighting in the world has grown rapidly, with Japan having the most patents, accounting for nearly 40%. However, if the number of patent applications in this field in mainland China is placed on the global corporate rankings, only Sony will have about 10 of the 1,500 patents, ranking 10th. What is more noteworthy is that a considerable number of local patents are controlled by enterprises outside the mainland. At present, about 16 countries and regions have applied for semiconductor lighting patents in the mainland, accounting for 40% of the total number of patents. From the perspective of the distribution of enterprises, the multinational companies headed by Japanese capital account for half of the country.
Compared with other domestic regions, there are still some gaps in the domestic semiconductor industry comparison. According to the research data, the main areas of domestic patent distribution are Taiwan, Beijing, Guangdong, Shanghai, Zhejiang, and Jiangsu. What is thought-provoking is that local companies account for less than 5% of the total industry patents, which is quite different from foreign companies' patent applications.
