Recently, the market competition has been fiercer due to the acceleration of technological change and the launch of intelligent products. In this situation, technology cooperation activities through networks rather than independent technological innovation activities of a single company or institution are recognized as a crucial strategy to gain competitiveness. Technology cooperation can take various forms depending on the target technology, and researchers have conducted performance analyses of technology cooperation types. However, there have not been data-based quantitative studies on the types and trends of technology cooperation for the target technology. In this paper, we explored the difference between the technology cooperation types by technology and time using the formal concept analysis method and co-patent information. In particular, the proposed methodology has been verified through the case study of electric vehicles, and it is intended to suggest the direction of technological cooperation according to specific technologies and cooperation targets in the future

Since the so-called diesel gates of German automobiles, interest in environmentally-friendly vehicles has been rising, among other alternatives, hydrogen-fueled electric vehicles with 0% vehicle emissions are expected to replace a significant portion of passenger cars. Here, we analyze trends of US, Europe, PCT (WO) 3-patent offices application of hydrogen-fueled electric vehicles and analyze the patent application trends of national and individual companies, the patent application trend of detailed technology through clustering analysis, technology competitiveness. The global market for hydrogen-fueled electric vehicles, which is currently only 0.01% of other alternatives, is expected to grow to several percent in 2020. Major automobile makers such as Japan, United States of America, Germany, and Korea continue to fiercely compete for eco-friendly vehicles.

The objective of this study is to investigate patent trends of Daegu city which tries to introduce environment friendly energy and to develop new technology or new industry sprung from technology convergence on smart decentralized energy technology and other technologies. After applying network analysis to corresponding groups of technology or industry convergence, strategy for future energy convergence industry is provided. Patent data applied in Daegu city area are used to obtain research goal. The technology which contains several IPC codes (IPC Co-occurrence) is considered as a convergence technology. Path finder network analysis is used for visualizing and grouping by using IPC codes. The analysis results categorized 13 groups in energy convergence industry and reclassified them into 3 cluster groups (Smart Energy Product Production Technology Group, Smart Energy Convergence Supply Technology Group, Smart Energy Indirect Application Technology Group) considering the technical characteristics and policy direction. Also, energy industry has evolved rapidly by technological convergence with other industries. Especially, it has been converged with IT industry, and there is a trend that energy industry will be converged with service industry and manufacturing industry such as textile, automobile parts, mechanics, and logistics by employing infrastructure as well as network. Based on the research results on core patent technology, convergence technology and inter-industry analysis, the direction of core technology research and development as well as evolution on decentralized energy industry is identified. By using research design and methodology in this study, the trend of convergence technology is investigated based on objective data (patent data). Above all, we can easily confirm the core technology in the local industry by analyzing the industrial competitiveness in the macro level. Based on this, we can identify convergence industry and technology by performing the technological convergence analysis in the micro level. 1

Zinc Sulfide (ZnS) is one of the II-VI semiconducting materials, having novel fundamental properties and diverse areas of application such as light-emitting diodes (LEDs), electroluminescence, flat panel displays, infrared windows, catalyst, chemical sensors, biosensors, lasers and biodevices, etc. However, despite the remarkable versatility and prospective potential of ZnS, research and development (R&D) into its applications has not been performed in much detail relative to research into other inorganic semiconductors. In this study, based on global patent information, we analyzed recent technical trends and the current status of R&D into ZnS applications. Furthermore, we provided new technical insight into ZnS applicable fields using in-depth analysis. Especially, this report suggests that ZnS, due to its infrared-transmitting optical property, is a promising material in astronomy and military fields for lenses of infrared systems. The patent information analysis in this report will be utilized in the process of identifying the current positioning of technology and the direction of future R&D.

As recognized by all scientific and industrial groups, carbon dioxide(CO2) capture and storage(CCS) could play an important role in reducing greenhouse gas emissions. Especially carbon capture technology by dry sorbent is considered as a most energy-efficient method among the existing CCS technologies. Patent analysis has been considered to be a necessary step for identifying technological trend and planning technology strategies. This paper is aimed at identifying evolving technology trend and key indicators of dry sorbent from the objective information of patents. And technology map of key patents is also presented. In this study the patents applied in korea, japan, china, canada, US, EU from 1993 to 2013 are analyzed. The result of patent analysis could be used for R&D and policy making of domestic CCS industry.

글로벌 경쟁 심화와 제품 수명 주기의 단축으로 인해, 기업은 경쟁력을 높이기 위한 한 방안으로 기술의 가치 평가에 더 많은 관심을 가지고 있다. 이에 따라, 기술(특허)을 둘러싼 가치평가의 문제가 국가와 업계의 핵심 쟁점이 될 것이며 중립적으로 특허가치를 평가해 주는 본 연구의 시스템이 유의미할 것이다. 본 연구는 특허의 서지적인 정보와 컨조인트 분석을 활용하여 객관적인 기술 가치 평가를 위한 체계를 개발하고자 한다.특히, 본 연구에서는 특허를 3가지 속성－기술성, 시장성, 권리성－으로 구분하고 속성별 3가지 요인을 도출, 가중치를 추정하고, 이를 통해 기술 가치 평가 체계를 제안한다. 이를 위해 첫째, 특허의 서지적인 특성을 고려한 세부 요인을 도출하고, 각 세부 요인을 계산하기 위한 방법을 정의한다. 둘째, 실제 특허를 거래한 거래 자료를 기반으로 하여 컨조인트 분석을 활용해서 특허의 속성별 가중치와 요인별 추정치를 도출한다. 셋째, 요인별 가중치를 토대로 특허 가치를 중립적으로 평가할 수 있는 평가 방법을 제안한다. 본 연구에서 제안하는 평가체계는 실제 거래 가격에 미치는 요인별 영향력을 판단하여 반영하였으므로, 특허의 기술 가치 평가에 유용하게 활용 될 수 있을 것이다. 전문가 평가에 절대적으로 의존하는 평가방법에서 벗어나 시스템화 된 방법으로 가치 평가를 한다는 점에서 금전으로나 시간적으로 절약의 효과를 기대할 수 있으며 중립적인 평가 체계를 제공할 수 있을 것으로 기대된다.
