Japan is the world's strongest nation in parts and materials for semiconductors, automotive parts and optical products, an analysis has found. In contrast, Korea is strong in new home appliances, displays, rechargeable batteries, and semiconductors among others.
The analysis was conducted by the AI-powered Technology Opportunity Discovery (TOD) system developed by the Korea Institute of Science and Technology Information (KISTI). The institute analyzed patented products of major countries using the TOD system.
The study analyzed changes in the number one patented products of five countries, including Korea, the United States, Japan, Germany, and China, based on product data extracted from U.S. patents over the past 10 years. The number of countries with more than 100 first-ranked products was four, with the United States having the highest number of 4,914. It was followed by Japan (1,991), Germany (264) and Korea (177). The results showed that the top four countries dominated first-ranked products.
The United States had a wide variety of first-ranked products throughout all industries, particularly, in the medical bio and aerospace sectors. The country also led nations in patents on system semiconductors, an area that has recently been selected as Korea's flagship industrial item.
Japan had a number of first-ranked products in the fields of automobiles and related parts including electric vehicles, parts and materials for semiconductors, optical products, and printers, but market shares of these number one products are on the decline. Representatively, Korea outclassed Japan in some of basic material parts such as anisotropic conductive film, adhesive film, compensation film, and driver ICs. Therefore, Korea will place first in basic material parts in the future according to the analysis.
Korea secured the world's strongest competitiveness in the area of new home appliances such as robot cleaners and dryers while taking first place in the 'new memory' sector such as 3D semiconductor, Re RAMs, and P RAMs. In addition, Korea continued to remain strong in future displays such as 3D displays, telecommunications and rechargeable batteries.
In addition, Germany, a technological leader in Europe, had many first ranked items in automobiles and related parts, and also had strengths in chemical materials.
In the past five years, in terms of number one product changes, the United States and Japan accounted for 20 percent, each but Korea 48 percent. This is because Korea has outperformed competitors by launching innovative products in various fields through continuous and dynamic technology development activities.
