Objectives : The purpose of this study is to present trends and contents of herbal Korean Medicine patches by analyzing the herbal patches in Korean patents. Methods : Electronic search for herbal patch patents was conducted in KIPRIS (Korea Intellectual Property Rights Information Service). Korean patents that were registered by January 1, 2018 were selected in study. Patents that were not using herbal medicine or not related to patch were excluded in this study. The applicant, application date, International Patent Classification (IPC), contents and adhesive site of patches, target diseases, model of experiment and extraction methods were analyzed. Results : A total of 17 patents were included in this study. In applicant analysis, 61.5% of applicants were corporations. All IPCs in patents were involved in Section A (Human necessities & Agriculture) and 66.7% of IPCs were A61K (Preparations formedical, dental, ortoiletpurposes). In types of patch, 8 patents were hydrogel patches (47.1%), followed by 3 heating patches (17.6%). Skin related symptoms were the most targeted diseases (52.9%), Human was the most used model in experiments. Solvent extraction and hot water extraction were used frequently, and some patents had no limit for extraction were also existed. Conclusions : The study results will be helpful to diversify formulation of herbal medicine, to expand market scale of patent and to develop new application using Korean medicine. In order to establish sufficient data for utilizing patent technologies, more patent studies providing analyzed patent information are needed.

In an attempt to develop comprehensive evidence-based methods for evaluation of the R&D performance of cross-disciplinary projects, a joint bibliometric analysis of patents and publications was performed for two industry-university-government collaborative projects aimed at commercialization: Hokkaido University Research & Business Park Project (2003-2007; 63 inventors; 176 patents; 853 papers), and Matching Program for Innovations in Future Drug Discovery and Medical Care - phase I (2006-2010; 46 inventors; 235 patents; 733 papers). Besides the simple output indicators (for five years period), and citations (from the publication date to the end of 2012), science maps based on the network analysis of words and co-authorship relations were generated to identify the prominent research themes and teams. Our joint analysis of publications and patents yields objective and mutually complementing information, which provides better insights on research and commercialization performance of the large-scale projects. Hence, such analysis has potential for use in the industry-university project's performance evaluation.

1. Objectives : The purpose of this study is to analyze for the patent application tendency in SCM(Sasang Constitutional Medicine). Recently, in SCM, many researches are made public through papers. However, in the patent area, the research results are less than the papers. 2. Methods : We collected patents about SCM using wintelips program. We analyzed patents according to the year, author, topic, and etc. 3. Results : We collected 151 patents using search system with wintelips program. After detailed analysis on SCM patent, we got to know that SCM was a growing field. In the collected patents, the patents on diagnosis technology were the majority and system of providing information were the second largest. 4. Conclusions : We think that the SCM field is growing at a fast pace with high activity, and this research should be updated annually.

This study presents a new method to evaluate patents by public R&D program using patent citation network analysis. I used forward citation, degree centrality, betweenness centrality and page rank as the dependent variables which represents the quality of patents. I used primary independent variable as a dummy of public R&D program and controlled patents characteristics, applicant characteristics, technological characteristics and year effect. The empirical result shows that the patents of public R&D program is superior to other patents in regard to the number of forward citation, the degree centrality, the betweenness centrality and the page rank. This empirical result implies that patents of public R&D program directly and effectively connects technologies. Also patents from public R&D program connects important technologies.

This paper explores the determinants of the economic value of patents using a survival time analysis. The analysis is based on renewal information of about 250,000 patents filed from 1984 to 2005 in the Korea Intellectual Property Office. A patent right is valid only when its owner pays yearly maintenance fees. Failure to pay causes patent rights to be lapsed. We use the fact that more valued patents live longer and the lengths of their renewals can be closely related to their value. The value can be affected not only by its own technological aspects such as quality and breadth, but also by characteristics of its owners such as innovativeness and age. This paper presents patent-specific and firm-specific characteristics which influence patent value. The result of analysis implies that patent value depends on both the technological contents of the patent and general capabilities of a firm.

From its foundation until 2004, ETRI has registered over 1,000 US patents. This letter analyzes the characteristics of these patents and addresses the explanatory factors affecting their citation counts. For explanatory variables, research team related variables, invention specific variables, and geographical domain related variables are suggested. Zero-altered count data models are used to test the impact of independent variables. A key finding is that technological cumulativeness, the scale of invention, outputs in the electronic field, and the degree of dependence on the US technology domain positively affect the citation counts of ETRI-invented US patents. The magnitude of international presence appears to negatively affect the citation counts of ETRI-invented US patents.

To investigate the technology trends in organic farming using patent analysis, total 1,026 patents in organic farming in Australia, EU, Japan, Korea and USA between 1974 and 2014 were analyzed. The number of the patents applied in organic farming was largest in Korea, followed by Japan and the USA. Since 2000, the patent application in Korea and USA increased drastically, while in Japan the patents in organic farming were applied steadily in the late 1980s. The applied patents in organic farming were mainly dominated in the field of organic production technology (AA) especially in Korea, while those in environmental assessment were merely applied. Most patent appliers were biased to private applier (80%) than national institutes including university. With this study, it is highly recommended that national interests and R&D on the organic farming fields are needed to meet the food safety.
