It is becoming increasingly clear that participation in the 'new economy' driven by scientific and technological advances will be the way to achieve global prosperity in the 21st century. An analysis of the patents assigned to a particular country, using the techniques in this study, provides a means to objectively assess the potential for participating in that prosperity, and to identify strong and weak area in technological potential. The analyses are based on Korean-invented patents issued in the United States, and on the citation analysis techniques that link these patents with other 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.

Many problems making the use and management of patents arduous is caused by the difficulty in knowing the proper value. This study has suggests the methods to evaluate the value of patents by using a quantitative assessment scale as an alternative or complementary measure instead of the existing subjective evaluation tools. This study is to find a method to determine the capability and level of research and establish the scheme of use and management of patents by using the citation index as a quantitative assessment measure. The data used in this paper has been obtained from a public-sector R&D institute, the K-Institute in Korea.

Utilizing the patent application data between 1997 and 2002, this study focuses on analysing the impact of patents on firm value. Especially we attempt to examine the difference of patents between venture firms and general firms. This paper first shows that the number of the patent applications of general firms listed on the securities market are more than those of venture firms listed on KOSDAQ. It is thought that this result is originated from facts that the size of firms of the securities market is usually bigger than the firms of KOSDAQ and that these large firms could manage R&D more efficiently. Second, this paper reports that there is no difference in the ratio of patent maintenance between venture firms and general firms. Both venture firms and non-venture firms would do their best to keep their patents after patent regisration. Third, in the regression of patent index and firm growth, we find that the excellence of patent and the number of patents per employee would have an impact on the growth of firms. Fourth, the regression of patent index and profitability shows that the excellence and the number of patents per employee might have an effect on the profitability of firms.

Objective: This study provides strategies of how to effectively convert an invention, created at universities or government-funded research institutes, into a strong patent with the clear understanding of its unique technological characteristics. Background: Regardless of the amount of research funds available in our country and the decent number of intellectual property rights created using the funds, there was a deficit of more than KRW 6 trillion in the technology trade balance related with intellectual property rights in the year of 2014. One of the reasons was that the vast number of patents that were being produced by universities or by government-funded research institutes were merely performance-based patents, namely, so called "patents for patents". Another reason is that developed technology from research and development could not be transformed into a strong patent right properly due to the lack of related knowledge. Method: After reviewing various references mentioned on the patent strategies, the definition of a strong patent and the strategies of producing a strong patent for an invention drawn out from research performance will be supplied. Results: To produce a strong patent right at universities or government funded research institutes, one should use strategies for strong specifications, strategies of product patents and method patents, strategies of patent portfolios, strategies of know-how, strategies of inventions defined by numerical limitation and strategies of parameter inventions for a more strategic approach. Conclusion: Strong patent rights will be produced with the use of effective patent strategies provided in this study. Application: It is estimated that the results of this study will aid the establishment of strong patents for inventions developed by research performance at universities or government-funded research institutions.

This study was conducted to determine the major patent and analyze the patent trend of unmanned and automated agricultural production for the open field operation. As a result of conducting a search for patent applications related to these technologies, 1,080 valid patents were selected by evaluating the relevance of the patents and removing noise patents. As a result of the country-based analysis using the selected valid patents, it was found out that the largest number of patent applications were filed in the United States with 541 cases, followed by Japan with 326 cases, the European Union with 128 cases, and Korea with 85 cases. Upon classifying the valid patents into core technology, the path generation and tracking technology accounts for 33% with 353 cases; the implementing control with environmental condition technology accounts for 22% with 236 cases; the robot design technology accounts for 21% with 228 cases; the plant and environment sensing technology accounts for 19% with 206 cases; the yield and quality monitoring technology accounts for 5% with 58 cases. Finally, 10 core patents were selected by performing a patent index evaluation. The United States registered all of the 10 core patents. The results showed that Korea falls behind in the open field-related unmanned and automated agricultural production, compared to other developed agricultural countries.

Augmented reality (AR), which is a live direct or indirect view of a real-world environment combined with virtual objects, has grown rapidly owing to its wide application potential. Despite the growth of AR technology and its increased attraction, however, little attention has been paid to identifying sub-technologies of this technology and their evolving trends based on the data encompassing industrial competition. In the present study, therefore we collect AR-related patents granted until 2015 and then identify technology topics constituting AR technology by applying topic modeling to the patents' textual data. Subsequently, this study determines dynamic evolving trends with respect to those identified technology topics using indicators and maps based on the technology topics' patents and citations. The contributions of this study are twofold; it provides an overall understanding of AR technology's evolving trends based on text mining of AR patents and will assist technology experts in academia and industry in determining further R&D in the near future.

The importance of intangible assets have increased unprecedentedly with the advent of the knowledge-based society. Investment in R&D has contributed to the rise of productivity and firm-value in the capital markets. but it is very difficult to determine the economic benefits of R&D investment, due to elusive link between time requirements and the realization of firm value from R&D investment. This study examines the differential effects of R&D expenditure and patents on firm-value by industry. Patents are intangible, proprietary rights that develops new products, plays a crucial role in market competition and results in research and development activities. If firms get patents, their R&D expenditure is assumed to be successful. The study analyzes whether successful R&D expenditure has a significant effect on the firm-value. The study considers two industries : high-tech industries and low-tech industries. These industries are expected to have different effect on R&D expenditure and firm-vale. The results of the study indicate that the successful R&D expenditure increased the firm-value. Successful R&D expenditure in high-tech industries more increased the firm-value more than that in low-tech industries.
