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.

Recently, the number of patent applications have been increasing rapidly every year as the importance of protecting intellectual property rights becomes more important. Patents must be inventive and have novelty. Especially, the novelty implies that the corresponding invention is not the same as the previous invention. To confirm the novelty, prior art search must be conducted before and after the application. The target of prior art search should include not only Korean patents but also foreign patents. Search of foreign patents should be supported by multilingual search techniques. However, a dictionary-based naive approach shows a limitation because some technical concepts are represented in different terms according to each nation. For example, a Korean term and a Japanese term may not be synonym even though they represent the same technical concept. In this paper, we propose a new method to map semantic similarity between technical terms in Korean patents and Japanese patents. To investigate different representations in each nation for the same technical concept, we identified and analyzed pairs of patents those are mutually connected with priority claim relationship. By performing an experiment with real-world data, we showed that our approach can reveal semantically similar technical terms in other language successfully.

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.

The study examines the effects of knowledge combination and of its interaction with technological change on the usefulness of inventions. We argue that inventing with knowledge components of prior art or with those in a variety of technical fields results in useful inventions, which changes after the emergence of dominant design because external actors' perception of which knowledge components are appropriate in current technological environments changes. Based on data from U.S. granted optical disc patents filed from 1992 to 2000, the results show that inventions with more new knowledge components relative to their prior art are less useful but that inventions with more diversified knowledge components are more useful. Also, the empirical findings show that the negative relationship between new knowledge components of inventions and their usefulness strengthens after dominant design emerges.

The Regional Cooperative Development Center (RCDC) at Tokushima Bunri University was established in 2005. The role of the RCDC is to make a social contribution and to assist in the development of human resources. The RCDC has made contributions to society by organizing meetings to facilitate the exchange of technology, holding public lectures, supporting joint research projects, providing technical assistance for manufacturers, making available the free use of equipment owned by the university and so on. Additionally, the RCDC has put much effort into giving undergraduate students internship opportunities at industries in the eastern part of Kagawa Prefecture (the TOSAN area) in Japan. The RCDC also trained a contracted researcher from a small company about the creation of intellectual property, including how to conduct a patent prior art search, how to prepare a patent specification, etc. The RCDC has worked in partnership with industry, Sanuki City Society of Commerce and Industry and Higashi-Kagawa City Society of Commerce and Industry in order to revitalize local communities.

The purpose of this study is to analyze the satisfaction of the manufacturing process and the satisfaction of manufacturing lesson in the lesson of model product manufacturing based on IoT(Internet of Things) for pre-service technology teachers. and we also analyzed 'smart farm' model production manufacturing among various products. The survey questionnaires with 8 questions to investigate satisfaction level of model manufacturing process, difficulties in manufacturing, and the satisfaction level of manufacturing lesson were collected from the 15 pre-service technology teachers and analyzed by using SPSS program. and The results of this study were as follows: First, the lesson satisfaction average level of pre-service technology teachers was high(M=4.22) in model product manufacturing process for the 'smart farm' model making based on the IoT. Second, the average satisfaction level of 'patent search and prior art search report writing education' was as high as 4.07. Therefore, the application of 'prior art search report writing education' showed that it helped to make the product. Third, the best high satisfaction level in the model production manufacturing procedure was 'education of inventive thinking method'(M=4.40). Therefore, the pre-service technology teachers showed that the 'education of inventive thinking methods' was very helpful from the idea design to the optimal selection of idea. The next order of satisfaction level was high(M=4.33) in 'design education and counseling' and 'guidance through selection of professor who guide the production manufacturing in addition to professors who are in charge of lesson'. Because they were helpful in solving the lack of knowledge of pre-service technology teachers. Fourth, satisfaction level with 'the presentation of model making results and exhibitions', 'presentations and participations of external event' was high (M = 4.13). Although the results of interviews with pre-service technology teachers showed that they suffered from lack of knowledge in various technologies, but it was an opportunity to learn things and felt a sense of accomplishment.

An increase of national R&D has brought the growth of research performance such as paper and patent quantitatively. However, the results of technology transfer and commercialization still leave much to be desired in Korea. Therefore, it has to be drawn up a plan for effective management & application of research performance created by public research institutes. We select four leading institutes (two universities, two government-funded research institutes) that performed efficient performance management & application. Then, we analyze the best practices and suggest contributions. The results show that four institutes build up a framework of performance management & application from research planning to technology transfer and commercialization. At an early planning phase, institutes set up definite needs-oriented goals, and prior review as well as prior art search is executed through experts. Besides, they systematically promote strategic patent management, technology marketing, post management, and so forth. For such a performance management & application process, capabilities have to be supported with regard to specialized organization, system, routine. This study can give an hint to improve performance management & application from public research institutes in Korea.
