Patent analysis is the extracting knowledge which is needed for the company's research and development strategy through accumulated worldwide patent database. In order to set the future direction corresponding technology which is scheduled to be developed, the technology trends and deployment processes are identified by analyzing results of present patent applications. The patent analysis provides the required results for analyzing present patent applications. In this paper, technology classification for related patent analysis methods and system, and patent analysis for desalination technology using solar energy development was carried out as well. The patents in Korea, USA, Japan, China, and Europe were searched. The technology trend desalination technology using solar energy was analyzed based on patent application year, countries, main applications, and each technologies. The application status of desalination patents showed a tendency to increase slightly. It was found that the number of patent for applied desalination was USA patent 21.0%, Japan patent 27.0%, China 24.8%, EU 2.7% and Korea patent 24.5%, respectively.

Technologies related scan-to-BIM for BIM-based reverse engineering techniques are beginning to be actively introduced in the A.E.C. industry, and the scalability of the technology is growing considerably. This study uses patent analysis based on objective data to find the right direction for Korean Scan-to-BIM technology by identifying the trends in Korea, the United States, Europe, and Japan. This was done using the WIPSON patent search system to find previous research on patent analysis related to building technology, theoretical consideration of scan-to-BIM technology, and published patents. We collected information, verified the process, and extracted valid patents. We used the effective patent data to analyze the annual trend of patent applications, national trends, and technological trends through the International Patent Classification (IPC) code, the types of the top 20 major applicants, and family patent trends.

기존의 부상기술 예측은 주로 정성적으로 이루어졌으나, 이는 많은 비용이 요구된다. 이에 대안으로 개발된 기술의 다양한 정보를 포함하는 특허를 활용한 정량적 방법이 있다. 기존에 특허 출원 건수를 이용한 정량적 예측 방법은 적은 출원이 이루어지는 부상기술 특허를 파악하는데 어려움이 존재한다. 이를 해결하기 위해, 선행연구에서는 추세선의 기울기를 사용하여 부상기술을 예측하였다. 그러나 출원 건수가 많은 핵심기술의 기울기가 크게 도출되므로 여전히 부상기술 파악에 어려움이 존재한다. 본 논문에서는 기술들의 Patent Power를 이용하여 상기 문제를 해결하며, 연도별 Patent Power의 변화를 이용하여 기울기를 구하고 부상기술을 예측한다. 또한, 최다 출원인을 확인하고 경영전략을 제시한다. 실험으로는 AR 분야의 특허 중 USPTO에 공개된 특허만을 사용하며, 부상기술로는 G02B가 도출되었다.
