Comparison of Chinese and Korean companies in ICT global standardization: Essential patent analysis

The latecomers from Asia-China and Korea-started to participate in information and communication technology (ICT) global standardizations as they accumulated technological capabilities. We observed the current situation of ICT global standardizations in those countries by analyzing the mobile communications standards, WCDMA and LTE, and derived interesting findings and meaningful implications from the analysis. First, this paper provides evidence of the differences in Chinese and Korean standard strategies; China is creating its own standard whereas Korea goes with global standardization. Second, this paper shows the subsequent results of the different strategies. In detail, we conducted an analysis based on (declared) essential patents in WCDMA and LTE. The results indicate that China and Korea hold a significant number of essential patents and their numbers compete with those of leading countries. However, the analysis shows that Korea accumulated domestic knowledge that enables the country to actively participate in standardization,but China still heavily relies on foreign knowledge, probably because China is attempting to create its own standard and accumulating knowledge takes a long time despite its efforts.Our findings have several implications for leading countries and other following countries.
