This study is trying to estimate the effect of survey of prior art on the technological performance of national R&D program, with the purpose to enhance understanding on the relationship between utilization of patent information and R&D activities. Patent and Technology Trend Research, one of the survey of prior art which gives the information about existing technology and patent trend to the project team has been carried out since 2005. In this paper, effects which Patent and Technology Trend Research has on the technological performance of national R&D projects are estimated by using multiple regression model considering input factors, characteristics of an agent and supplier of money. The result is that Patent and Technology Trend Research has positive and significant effect on the grant and application of domestic and foreign patent. This result can give an hint that the utilization of patent information make the R&D process efficient and effective.

연구 및 개발에 앞서 정확하고 효율적인 연구계획의 중요성에 대한 인식은 더욱 높아 가고 있다. 정확하고 효율적인 연구계획을 위해서는 목표수립, 명확한 연구 자금의 흐름, 사업화 계획 등 많은 조건들이 충족되어야 하지만, 그 중에서도 해당 분야의 선행기술 조사는 연구계획의 성패를 가름 지을 수 있는 중요한 인자 중의 하나이다. 선행기술 조사를 위해서 대부분의 연구자 혹은 기획자들은 지금까지 학술 논문에 의존하는 경향을 보여 왔다. 학술 논문만을 이용한 선행기술 조사의 높은 의존도로 인하여 학술 논문의 학문적, 기술적인 가치가 동일하게 인식되어 왔으며, 동시에 법적인 권리까지 내재되어 있는 특허의 중요성을 상대적으로 소홀히 취급하게 만들어 온 것은 사실이다. 모든 연구 기획이 사업화 또는 이익창출에 이용될 필요는 없지만, 적어도 많은 인력과 자금을 필요로 하는 연구결과를 사업화나 이익 창출의 기회로 사용하기 위해서는 학술 논문뿐만 아니라, 법적인 권리를 확인할 수 있는 특허 정보를 이용한 선행기술의 조사가 이루어져야 할 것이다. 본 연구에서는 나노 사이언스 또는 나노 테크놀로지가 융합된 화장품 분야의 특허들 중 2008년 8월 말까지 한국, 미국, 일본 및 유럽에서 공개되거나 등록된 특허를 대상으로 해당 특허들에 대한 소정의 기술분류를 통한 특허분석을 수행함으로써 한국의 나노 화장품 분야 특허들의 양적, 기술적 수준을 재확인 하고자 한다.

Prior art search is a core process of technology management performed by inventors and applicants, patent examiners, and employees in the patent industry. As a result of insufficient academic research on a systematic prior art search methodology, the process has been often carried out depending on the subjective judgment of researchers. Previous studies on exploring prior arts based on semantics have also have the risk of underestimating the similarity of major prior arts due to the nature of patent documents where the same technical ideas are expressed in various terms. In this study, we propose an effective prior art search methodology based on hierarchical citation analysis, which provides a clear criterion for selecting core prior arts by calculating weights according to the relative importance of the collected patents. In order to verify the feasibility of the proposed methodology, a case study was conducted to explore the core prior art of one patent in the display field. As a result, 10 core prior art candidates were selected out of the 206 precedent patents.

In the knowledge-based economy, firms are increasingly exploiting their intellectual properties, especially patents. However, firms usually fail to commercialize all of their patents and some of them are not used even for strategic purposes. Therefore managing sleeping patents constitutes one important aspect of firms' overall patent strategies. This paper considers market uncertainty, technology uncertainty and strategic uncertainty as the reasons for sleeping patents. We analyze how firms' patent-related activities can reduce sleeping patent ratios. The firms' activities examined in here are patent audit, preliminary evaluation, prior art and cooperation. Noticing the prevalence of sleeping patents, this paper contributes by providing insights into how firm's activities affect the sleeping patent ratios. Insights for practitioners and policy makers have been provided from the empirical results.

From the result of preceding study, there is no reinforcement such as dowel bar or etc. in Joint system of floating slab. Length of floating slab in preceding study is short than one of this study. If there is no reinforcement in the joint of long slab span, fracture of slab is predicted by difference between two slabs. Therefore using of dowel bar is demanded. In this study, General characteristic and preceding technology of dowel bar is researched for data of analysis study. And it is considered application of dowel bar in floating slab system.
