According to statistics from the Korea Chamber of Commerce and Industry, the proportion of semiconductor technology patents held by South Korea in the five regions of South Korea, the United States, Chinese mainland, Japan, and the European Union in the past 20 years has increased from 21 in 20032%, * to the current 24%。On the contrary, the proportion of semiconductor patents in Chinese mainland has increased fivefold in the past 20 years, from 14% before to 71 in 20227%。
In 2022, the total number of semiconductor patents in China and the United States will account for 929%, of which the United States accounted for 212% compared to 38 in 2013The share of 2% has decreased. The agency believes that with the fierce competition for semiconductor hegemony, the phenomenon of core semiconductor technology concentration in the United States and China has intensified, and South Korea, which was once a major country in semiconductor technology patent registration, has declined.
According to agency statistics, in the five years from 2018 to 2022, the number of semiconductor patent applications in the five regions of Chinese mainland reached 135428, ranking first, far exceeding the 87,573 in the second place United States. The data for Chinese mainland is based on the statistics of the China National Intellectual Property Office (CNIPA).
On the other hand, South Korea has applied for 18,911 semiconductor patents in five years, ranking third in the world and slightly ahead of Japan (18,602) in fourth place. An unnamed semiconductor industry source said, "With the development of semiconductor technology, it is difficult to increase the number of new patent applications, but considering that most enterprises and research institutions are still speeding up the registration of patents in necessary fields in order to seize technological opportunities, the semiconductor technology competition between Chinese mainland and the United States is also reflected in the scale of patent applications." ”
The agency said that in the past 10 years, Chinese mainland has obtained technology patents not only in the field of semiconductor small parts (materials, parts, equipment), but also in the fields of old general-purpose semiconductors and cutting-edge semiconductors. But in terms of the "cited index" (CPP), which measures the quality of patents, the U.S. is 696, 5 in South Korea15, while Chinese mainland is only 289。
Dr. Kwak Hyun (sound) of the Korea Intellectual Property Research Institute said, "The number of patent applications in various countries is an important indicator of the growth possibility and market expansion of the semiconductor industry in each country, although the current level of patent quality in South Korea is high, Chinese mainland is seeking qualitative growth based on quantitative growth, so it cannot be taken lightly." ”
In terms of Korean patents, in the past 20 years, there have been 25,159 memory semiconductors and 33,291 system chips, with system chip-related patents accounting for 57%. In contrast, the proportion of patents related to system chips in South Korea is too low. While South Korea's Samsung Electronics and SK hynix dominate the global memory chip market, some point out that South Korea must increase its development of system-on-chip technology in order to cope with the artificial intelligence (AI) market in the future. In addition, in order to maintain the competitiveness of Korean semiconductors, it is necessary to consider the provision of subsidies in a forward-looking manner.
Among the top 10 enterprises and institutions with the most patent applications for semiconductor technology, Samsung Electronics was the champion in 2003, and TSMC in Taiwan, China in 2012 and 2022 were the champions. Among the top 10 institutions in 2022, Chinese mainland institutions accounted for half, of which ranked second, Ping An ranked fourth, and Tencent ranked first.
