This study aims at analyzing the convergence of Internet-of-Things and wearables technologies using cooperative patent classification(CPC). CPC, introduced to an increasing number of technological fields of Korean patents, is expected to be widely used in Patent Informatics because the classification codes in CPC are more specific than those of IPC, which reflect the characteristics of technologies in detail with accuracy. CPC has seldom been used up to date and most of the previous researches on technological convergence used IPC. As a pre-analysis step for analyzing the trend of technological convergence of IoT and wearables, CPC and IPC codes assigned to each patent were compared. By applying association rule mining to the analysis of CPC codes, we identified the technological fields where convergence frequently takes place and examined the trend of technological convergence over time.

Melanin plays an important role in protecting human skin from UV radiation and determines the race and skin color. Melanin is also major target for developing skin-whitening cosmeceuticals. Recently, as the market size of skin-whitening cosmeceuticals has rapidly expanded, related researches and developments are also focused on maximizing the safety and efficacy. Also, patents of skin-whitening materials have been increasing steadily for ensuring the competitive power. Patent also shows the research trend of industry and institutes. In this review, we analyze the trend of research and development based on the patent application of skin-whitening cosmeceuticals.

This study was conducted to establish the research direction of heat stress in dairy cows by searching papers and patents. Research papers published before 2014 through National Digital Science Library (NDSL) and patents registered with United States Patent and Trademark Office (USPTO), Japan Patent Office (JPO), European Patent Office (EPO) and Korean Intellectual Property Office (KIPO) were investigated using the key words of heat stress index, genetics, facilities and feed. The research trend for heat stress in dairy cows was analyzed with 182 papers and 282 patents. Global warming due to increased atmospheric concentration of greenhouse gases is a major interest in recent years. The papers related with heat stress in cattle were increased after 2006. Besides, patents connected with facilities and feed will be increased due to development of ICT. In particular, the various studies including patents about heat stress in dairy cows will be needed to conduct because the climate of southern Korean peninsula is changing from temperate to subtropic.

The hydrogen storage is one of the key technologies to achieve the successful hydrogen economy and a chain to connect hydrogen production to its utilization. In this paper, characteristics and strong candidates of hydrogen storage technologies were analyzed from the objective information of patents. Also, the hydrogen storage technology trends and gaps were assessed using statistical or qualitative analysis. In this study the patents applied in Korea, Japan, US and EU from 10 or 20 years ago to 2011 were analyzed. The result of patent analysis could be used for developing or searching for promising technology of the hydrogen storage.

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.

This research entailed collecting foreign and foreign patents on technologies for process food related ginseng, creating category of patent technology searching and conducting quantitative analysis on each technology component and schematization. A technological trend of treating or preventing multiplicity of diseases has reviewed on 6,255 domestic and foreign patents from the year 1975 to 2004. Considering the increasing number of applicant and application of patent on technology of food manufacturing and processing in the world around year 2000, it seem that these technology is developing. The related technology seems in the initial stage and common research by related technology research centers, government organization and public corporation becomes active.

Recently, it has been trending toward speed-up not only in the passenger car but in the freight car. In this paper, the trend of the market demand for the technology of railway freight cars and the development direction of other country or company were studied by analysing the patent map. The effort for developing the technology is it seems to be more strengthened especially in the parts of bogie, brake, suspension. The increasing rate of the number of patent application from the United States of America is noticeable. The results of this paper can be used for making the development plans of competitive technologies and benchmarking of them.

Objectives : The aim of this study is to analyze the patent trend in Traditional Korean Tea. In this paper, we investigate the diversity of Korean Tea registered as patents focusing on the kinds of medicinal herbs used, processing methods, and types of tea. Methods : We collected patents data using KIPRIS, and WIPS database. We conducted Quantitative Analysis by year and main patentee, and Qualitative Analysis by patent's contents. Results : 313 patents are selected from 2001 to May 2017. The number of patents have been on the rise and reached 44 in 2014. Individuals have registered the most patents, followed by companies, Industry-University Cooperation Foundation, and local autonomous entities. Ginger, Omija and Cactus were used at high frequency among 109 tea containing one medicinal herb. Licorice and Jujube were frequently used among 204 tea containing more than two kinds of medicinal herbs. In classification of patent by efficacy, 'health promotion and function recovery' and 'treatment and prevention of diseases' are most frequently specified. 128 patents are presenting processing methods for medicinal herbs in the order of roasting, fermentation, and fumigation. Among 164 patents presenting tea types, liquid type accounts for more than half and there are 67 leached tea, and 32 powder tea. Conclusion : The analyses results showed that lots of new recipes, efficacy, processing methods and tea types are being studied and registered as patents. In order to help Traditional Korean Tea industry to develop, active patent registration and further study about up-to-date patent trend would be required.

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.

The paradigm of economy has been transformed into knowledge based economic paradigm in 21th century. Analysis of patent trend is one of the strategic methods for increasing their patent competitive power. However, this method is just presenting statistical data about patent trend or qualitative analysis about some core technology. In this paper, we forecast technology diffusion using patent information for more progressive analysis. We make an experiment with bass model and logistic model and make use of patent data about information-security technology for NCW as input data. We conclude that the logistic model is more efficient for forecasting and this technology is approaching to the age of technology maturity.
