Objective: The purpose of this study was to analyze the trend of ergonomics field in overall intellectual property rights in Korea, and suggest the direction for the future development. Background: Many ergonomists are trying to pursue optimal human well-being and safety, and create more convenient designs for human use. For these reasons, intellectual property rights may be used to protect the legitimate rights of originative and innovative ergonomic designs. Method: Intellectual property rights were reviewed by using Korea Intellectual Property Rights Information Service (KIPRIS), and then were classified and analyzed according to three intellectual property rights (patent, utility model, design), International Patent Classification (IPC) and ergonomics application areas. Results: The total number of intellectual property rights registered in the ergonomics field in terms of three intellectual property rights (patent, utility model, design) showed 48,814 which occupied 5.97% of the total registered Korea's intellectual property rights. Within three intellectual property rights, patent (87%) was recorded overwhelmingly higher than utility model (9%) and design (4%). Conclusion: The current trend of patent, utility model and design in the ergonomics field in Korea tend to increase over time. It is suggested based on the analysis in this study that continuing research and development should be focused on electricity section in accordance with the global trend. Application: The results of this study can direct the ergonomists to the areas of intellectual property rights in the ergonomics field that should focus on the research and development in terms of three intellectual property rights, IPC and ergonomics application areas.

Methods: To analyze the patent, a combinations of words such as "aconitum" or "korean aconite root" were used in search engine Kipris(www.kirpis.or.kr). The patents of aconiti ciliare radix were analyzed in three ways: year trend analysis, internatonal patent classification (IPC) code analysis related to content classification, and patent registration status analysis. Results: Among the patents found in the search results, 17 patents with significant contents were analyzed. Results showed that, first, patents were steadily registered until 2018, but recently there has been no new patent registration. Second, there were many patents related to efficacy verification and decoction method, and the number of IPC codes related to them was also high. Third, there are five patents maintaining the registration status, and they are patents related to the aconiti ciliare radix extraction method, toxicity removal, and combination method. Conclusions: In this study, the domestic patents of aconiti ciliare radix were analyzed. The analysis results of this study are expected to be exploited as basic data for the development of Korean medicine analgesics with fewer side effects by suppressing tuber toxicity and the creation of new medical technologies.

A technical analysis was conducted to predict the development trend for the highly efficient absorption type refrigeration system. The study was based on a submitted patent during January 1981 and December 2000 in Korea, Japan and America. The total number of extruded patents from the registered database was 24,822 and the filtering process makes the reduction of the data number to 3,510. Technical development of Japan for the absorption type refrigeration system is prominent compared to the other country due to approximately 75％ of the patents coming from Japan. When the patent is divided into two categories, the patent for component technology for the refrigeration system makes up 75％ and the refrigerating type technology 25％ of the patents. This shows technical development for the system component is advanced compared to the technology development for the system type. When the patents are classified by nationality of patent applicants, foreigners contribute up to 33％ of the patents in Korea. However, Japan's case shows the 99％ of the patents are invented by the Japanese. If the patents are classified to the International Patent Classification, most of the data for the absorption type refrigeration system belongs to IPC F25B.

Along with the rapid development of industrial technology, the industrial structure has been continuously changed. Accordingly, safety technologies have been gradually developed to be applied into various industrial fields as well, not limited to a specific industry area. As a result, it became important to analyze and predict trends of safety technology development in order to establish technology strategies for industrial safety. In particular, since patents are easily accessible to gather the technology and business information, many studies have highlighted technology forecasting using patent information. Thus, this study proposes the patent analysis of monitoring trends of safety technologies of industry fields, taking into account both static and dynamic aspects through index and text analysis. First, patent documents containing safety-related keywords are collected from the WIPSON database for extracting technology information. Then, the development trends of safety technologies by industry fields are identified and analyzed through the analysis of indicators such as marketability, growth, and activation. The results of various indicator analyses of safety technologies are visualized to compare among industrial safety technologies for businesses and technology developers. Second, textmining algorithm is applied to identify trends of specific technology keywords of major industries extracted from patent index analysis. As a result, it is expected that the safety manager uses the patent analysis of safety technologies to provide safety technology information with safety-related companies and institutes. The extracted safety technologies are applicable to business practice and predict future promising technologies.

This study analyzes patent trends regarding farming-related technologies such as breeding or nursery technology, production systems, and new cultivation methods in order to provide objective patent information about the trends of R&D on marine products' proliferation or farming. Presently, in Korea, we try to secure marine living resources through the formation of artificial resources instead of environmental improvement policy or resource management policy. However, this is not about eliminating the causes of marine environment destruction but just the policy for improvement, so it is needed to revise the related policy with more ultimate measures. And it is necessary to develop technology that can secure the rights by integrating patent application strategies from the stage of R&D for medicine that can be utilized in chief farming countries and provide intensive support for the research centering around strategic varieties for farming in each region as well as strategic national farming varieties afterwards. Also, the analysis shows that it is urgent to make applications overseas based on domestic applications in order to develop technology that can be commercialized in not just Korean but overseas market as well.

This paper deals with methods for determining the reasonable royalty rates in the valuation of patents. To calculate the reliable reasonable royalty rate of a patent, we review pros and cons of the 25% rule royalty calculating method and the recent trend of this method. We also review the game theory of Nash Bargaining equation and review the Investment of Rate of Return Method according to the financial analysis. Next, we refer to the reasonable royalty damage cases among the recent patent infringement cases in USA and analyze the corresponding patents. We extract the patent indicators from the patent bibliographic information. Finally, we obtain a regression model for calculating a reasonable royalty rate using the patent indicators and the reasonable royalty rates in the recent patent infringement cases.
