Abstract :
The goal of this study was to examine how ICT technologies are converging with KIPO issued patents. To understand what has been happening in ICT convergences, the patents of 87 main IPCs that combine ICT classifications (OECD, 2008) and the classification of ICT industries [10] were selected from KIPO database, and then the converging technologies were chosen based on the co-classification method. [12] For activity analysis, the patent activity index and normalized Herfindahl index were mainly used.
