Abstract

Research and development is entering on more complicated aspect gradually and tends to increase sharply in a quantitative manner. Technology competition is getting higher. This study intends to raise recognition of a necessity of productivity in a rapidly-changing research and development field and to suggest alternatives for improving its research productivity. For it, the research productivity was analyzed by utilizing two processes of patent and paper analysis. In this paper, we propose a patent analysis method for technology forecasting of the Forward Osmosis Membrane using objective patent data. The application status of patents showed a tendency to increase slightly. The current of FOM technology development in such countries as Korea, USA, Japan, China and EU was analyzed by classifying the patents for 1990 through 2011 according to registration country, assignee, calendar year and technology area.

연구개발은 더욱 다양한 형태를 보이고, 결과물도 급격한 증가 추세에 있으며 기술경쟁은 점차 심화되고 있다. 본 연구는 빠르게 변하고 있는 연구개발의 향상을 위한 필요성과 연구생산성 도출을 위한 대안을 제시하는데 목적이 있다. 이를 위해 특허와 논문분석이라는 두 가지 기법을 활용하여 정삼투막 기술 분석을 하였다. 지금까지 출원된 기술에 대한 객관적이고 광범위한 정보를 포함하고 있는 특허데이터를 정량적으로 분석하여 정삼투막에 대한 기술적 예측에 필요한 특허분석 방법을 제안한다. 1990~2011년 동안의 한국, 미국, 일본, 중국 및 유럽에서 출원된 특허에 대하여 출원국별, 출원인별, 연도별, 세부기술 분야로 분류하여 비교함으로써 기술개발 현황을 분석하였다.
