Abstract
This study analyzed technological competitiveness of five major countries by using patent information that is typical intellectual property. Technological activity, patent competitiveness, market securement and patent concentration were designed as evaluation items for the technological competitiveness analysis, and the number of patent applications, family patents and triad patent families, and the paten concentration index were reflected as evaluation factors to be scored. For technologies to be analyzed, it referred to the energy harvesting technologies selected as 500 future technologies in the future technologic white paper 2013 published by KISTI. They were classified into technologies using thermoelectric, piezoelectric and photovoltaic elements, which are main detailed technologies of the energy harvesting technology, to investigate and analyze patent information for each detailed technology to understand their technological competitiveness. As a result, the United States ranked top with 75 and 70 points in the technology using thermoelectric and piezoelectric elements respectively, and Japan ranked top with 90 points in the energy harvesting technology using photovoltaic elements. It was analyzed that Korea held the second rank in the field using piezoelectric and photovoltaic elements, and the fifth in the technology using thermoelectric elements.
