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.

An analysis was conducted to predict technical trends for the highly efficient absorption refrigeration system. The study was based on submitted patent during January 1981 and December 2000 in Korea, Japan and U.S.A. The analysis are divided with two categories as component technology and refrigeration type technology. The analysis was focused on component technologies rather than the absorption cycle or system technologies.

This study aims to examine the R&D trends on Big Data sector through patent analysis and to suggest directions of the R&D activities in Korea. According to the results of analysis, the R&D trends of Big Data sector have shown two characteristics. First, the US has monopolized the world market of Big Data Sector. The patent activities of US have shown relatively even throughout every technology. And the average share of each technology is over 40%. Second, the trends of R&D have been changed. In the past, data analysis and processing technologies were the mainstream, whereas data operations and management technologies are mainly featured. However, the patent applications in Korea have been concentrated on storage technologies, while the applications for data operations and management technologies are correspondingly low; therefore, it seemingly needs urgent research and development of relevant technologies.

This study attempts to develop a methodology that analyzes patent applications to identify future skills, in particular in the sector of information security, recently into the spotlight. Matching skill elements from the International Patent Classification (IPC) with skill units from job analysis, the study tries to track trends in the skills needs based on IPC time-pattern. It then verifies the validity of the outlook for future skills needs by addressing the situation through the use of patents. The research assesses the usability of patent information for this type of analysis. While this study is limited to the information security sector by using Korean patent information, it can be expanded in the future to other areas and patents in the United States and Europe.

최근의 국제 표준화 동향은 특허 등 IPR(지적재산권)을 필수적으로 고려하고 있는 상황으로서, 선진 각국은 자국 개발 기술의 IPR 확보와 이의 국제 표준화를 연계시킴으로써 세계 정보통신 시장의 선점을 통하여 핵심적인 위치를 공고히 하고 있다. 본 고에서는 국제 표준화 기구(ITU-T)의 지적재산권 정책 및 관련 논의 동향을 살펴본다. 그리고 ITU-T에서 개발한 권고에 포함된 특허에 대하여 각 국가 및 기관이 대상 권고 및 특허 관련 정보 등을 ITU-T 사무국(TSB)에 통지한 Patent Statement and Licensing Declaration(특허 성명 및 라이선싱 선언서)로 구성된 Patent DB 분석을 통해 ITU-T의 개발 권고에 포함된 각 국가 및 주요 기관별 특허 현황을 살펴보고 그 함의를 모색해 보고자 한다.

The purpose of this paper is to analyze the trends of technological development in the field of portable multimedia player (PMP) through patent information of major countries, and evaluate the technological Position of PMP. In the first place, we will carry out a quantitative analysis in terms of the annual trend of patent applications in the field of PMP, the technological position of PMP through portfolio analysis, the share of patents by applicant, the worldwide innovation leader of major countries, and the patent trend by IPC. Secondly, we will measure the technological level of PMP using indicators including cites per patent (CPP), science linkage (SL), and patent family size (PFS). Finally, we will evaluate the directions of research or technology development and the technological competitiveness of major countries. This evaluation could give us some useful policy implications on the strategy of R&D in PMP.

For the human body shape information, body measurement techniques using a tape measure or image analysis are used. However, there is a demand for a method with high measurement accuracy and reproducibility while being simple. In this paper, domestic and foreign patent research related to body size measurement technology was conducted to identify the development trend of the related technology. WISDOMAIN DB was used to search for patents published in Korea, the United States, Japan, and Europe, and valid patents were derived by defining the technical scope of major and medium classifications and sub-categories. For the derived patents, patent trends by year, major applicants by country, and the status of technological fields were analyzed. In the field of body size measurement technology, the proportion of patent applications filed in Korea is high, indicating that Korea is leading the patent application in this field. Although the number of patent applications in the field of sensor-type measurement technology was not large, it has an advantage in measurement simplicity, so the development of related technology is expected to contribute to the improvement of measurement accuracy related to body composition analysis.

Smart farms are receiving a lot of attention as a way to solve the chronic labor shortage and aging problems in agriculture. The smart farm industry, called the 6th industrial revolution, needs to strengthen its competitiveness. In order to apply innovative IT technology to agriculture, it is important to collect and analyze information about prior research or patents. This paper examines smart farm patent trends through 5,789 patent data related to smart farm using the domestic patent information search service(KIPRIS). This paper examines the domestic patent trends of smart farm information through keyword network, ego network, simultaneous appearance network, and bigram network analysis. As a result of network analysis related to smart farm patents, patents related to smart farm systems and control technologies were the most common. This paper can provide help in setting the direction of future smart farm-related patent research.

Objective : The purpose of this study is to analyze for the patent application tendency in Korean Oriental Pediatric Medicine. Recently, many studies are published in Korean Oriental Pediatric Medicine. However, in the patent area, the research results are few. Method : For patent analysis, we searched the database kipris (http://www.kipris.or.kr) which managed in the Korean Intellectual Property Office by keywords about Korean Oriental Pediatrics. They are technically analysed by year and IPC, patent's contents, main applicant and organization. Results : 1. Patents by year have been on the rise 2 in 1997 to 32 in 2011. 2. Our findings are Section A61;182, A23;46 in IPC analysis 3. In classification of content, 'application-food' is 67 cases, 'application-functional cosmetic' is 18 cases, 'application-clothes' is 5 cases. 4. Korea Institute of Oriental Medicine have 14 patent cases, that is the most patent agency in possession. Main applicants are person > company > university > laboratory > state or local government. Conclusion : This study shows that it has high frequency of daily necessity in patent cases about oriental pediatrics. The results are more distributed 'applied' field than 'treatment' field. The patent information should be connected research achievement results in Korean Oriental Medicine.
