Abstract
이 논문에서는 특허정보의 분석을 통해 휴대용 멀티미디어 단말기(PMP) 분야의 국내외 기술개발 동향과 주요국의 기술적 위치를 규명하고자 한다. 이를 위해 PMP 관련분야 특허의 연도별 출원동향, 특허 포트폴리오 분석을 통한 관련기술의 발전단계, 출원인별 특허 점유율, 주요국의 당해 분야 혁신 리더 동향, 국제특허분류(IPC)별 특허출원 동향 등을 분석한다. 그리고, 주요국의 PMP 분야 기술수준을 분석한다. 이를 위해 특허당 인용건수(CPP), 과학연계지수(SL), 시장확보지수(PFS) 등의 지표를 활용하기로 한다. 또한, 주요국의 PMP 분야에서의 연구개발 단계를 살펴보고, 이들 국가의 기술 경쟁력을 관련된 과학기술 분야의 논문과 특허를 이용한 인용분석을 통해 평가하고자 한다. The purpose of this paper is to analyze the trends of technological development in the field of portable multimedia player (PMP) through patent information of major countries, and evaluate the technological Position of PMP. In the first place, we will carry out a quantitative analysis in terms of the annual trend of patent applications in the field of PMP, the technological position of PMP through portfolio analysis, the share of patents by applicant, the worldwide innovation leader of major countries, and the patent trend by IPC. Secondly, we will measure the technological level of PMP using indicators including cites per patent (CPP), science linkage (SL), and patent family size (PFS). Finally, we will evaluate the directions of research or technology development and the technological competitiveness of major countries. This evaluation could give us some useful policy implications on the strategy of R&D in PMP.
