At present, the world has initially formed an industrial pattern centered on the three major regions of Asia, North America and Europe, and a technological competition pattern with Japan's Nichia Chemical, Toyoda Gosei, the United States' Corey, Preh and Germany's Osram as the patent core. Several major international manufacturers from Japan, the United States and Europe represent the upstream level of today's LED and have a significant impact on the development of the industry. This influence is not only reflected in products and income, but more importantly, in the monopoly of technology. More than 50% of the core patents are in the hands of these major manufacturers. And my country's LED is still at a low-end level, about 80% of the products are concentrated in landscape lighting, traffic lights and other application markets, and the general lighting market is still being promoted.

With the vigorous development of the domestic LED market, more and more foreign companies are turning their attention to China. In recent years, the number of patent applications in the LED field in my country has increased significantly year by year. According to the "Semiconductor Lighting Patent Risk Analysis Research Report" by the Development Research Center of the State Intellectual Property Office, 22 countries and regions around the world have applied for patents in my country, and the top five countries are Japan, South Korea, the United States, and Germany. and the Netherlands. Among them, Japan is far ahead with 1,306 patent applications, accounting for 24% of the total number of applications. In terms of valid patents, the ratio of domestic patent applications to foreign patent applications in China is about 4:5. However, in these domestic patent applications, Taiwan occupies a large share, and its effective invention patents account for 53%. From the perspective of the distribution of the industrial chain, foreign companies mainly have patents in the field of chips and packaging. Half of the core LED inventions have filed patent applications in my country, and foreign LED companies have mastered the vast majority of core patent technologies.
