The trends of patents related to natural dyeing were examined in order to guide the development of natural dyeing into a high value-added technology. Total 181 patents data provided from KISTI were analyzed and following results were drawn. Korea had the overwhelming number of patents related to natural dyeing over Japan or United States of America from 1970 to 2007. In case of domestic, the number of patent applications were heavily focused on the metropolitan area in 1990's, but started to increase in the Honam region and Youngnam region in the first half of the year 2000 which indicated that the researches and the developments of natural dyeing were very active. In the case of foreign countries, most of their patent applications comes from the corporation such as a company while the number of patents applications from individuals overwhelms that of corporation in South Korea. Also, more of individuals' patent applications were denied than corporations' patents applications. The vegetable dye, a type of dyestuff which is a research subject for patent application, had the most research done above all other dyestuff.

Patent analysis is the extracting knowledge which is needed for the company's research and development strategy through accumulated worldwide patent database. In order to set the future direction corresponding technology which is scheduled to be developed, the technology trends and deployment processes are identified by analyzing results of present patent applications. The patent analysis provides the required results for analyzing present patent applications. In this paper, technology classification for related patent analysis methods and system, and patent analysis for desalination technology using solar energy development was carried out as well. The patents in Korea, USA, Japan, China, and Europe were searched. The technology trend desalination technology using solar energy was analyzed based on patent application year, countries, main applications, and each technologies. The application status of desalination patents showed a tendency to increase slightly. It was found that the number of patent for applied desalination was USA patent 21.0%, Japan patent 27.0%, China 24.8%, EU 2.7% and Korea patent 24.5%, respectively.

Patents often serve as leading indicators of technological change. This patenting activity reflected R&D (Research & Development) of new technology. The purpose of this study is to set up a forecasting model that anticipate the number of domestic patent applications and the number of patents granted relating to R&D inputs (R&D expenditure, R&D manpower) at the level of three industrial sectors in Korea : electrical-electronic, machinery, chemical etc. In this study, forecasting models were used trend extrapolation and a set of regressions. Both Theil's inequality coefficient and MAE(Mean Absolute Error) were utilized to test the precision of predicted value. The patent data and the R&D data were based on Indicators of Industrial Technology data throught 1980 to 1996. The major results obtained in this study are as follows (1) The regression model is more useful for forecasting the trends of the number of patent applications and patents granted than the trend extrapolation method. (2) The variance of Theil's inequality is smaller in patent applications than in patent granted.

To study the development trends of domestic apparel design, we analyzed patent applications that were applied to the field of apparel design. It was presumed that economic and social environment have affected directly on the number of apparel design applications. Since year 2000, the whole number of apparel design applications has shown a remarkably increasing tendency, but depending on the items, the trends of patent applications have different tendency. While the number of applications regarding western costume such as a jacket, pants, suit and coat has been increasing from mid 2000s, the number of applications regarding Hanbok and undergarments have been decreasing from mid 2000s. In early 2000s, there were a lot of applications relating to design creation due to combination of color and form in apparel design. However, from mid 2000s, variety of techniques such as granting functional characteristics, asymmetry construction, introduction of various textiles, techniques of draping were being applied in design creation.

In this study, we examine the effect of TRIPS on the relationship between R&D expenditures and patent applications in manufacturing firms. The first set of tests examines the association between patent applications and R&D expenditures and firm specific factors such as firm size and capital intensity. The next set of tests adds environmental factors including R&D intensity of the industry and development of TRIPS. We divide the sample period into three subperiods according to the progress of TRIPS subperiod 1(1984-1988) before TRIPS, subperiod 2(1989-1994) after negotiation of TRIPS and subperiod 3(1995-2000) after agreement on TRIPS. Regression model reveals that the coefficient on firm size is significantly positive over the all sample Period, while that of R&D expenditures of R&D intensive firms is significantly positive in subperiod 2 and 3(1989-2000) and that of capital intensity is significantly negative only in subperiod 3(1995-2000). The findings suggest that the efficient intellectual property system promotes the patent application of R&D intensive firms.

As the concrete pouring work relies on manual work, there is a lot of room for automated equipment development. In this study, as a basic study on the development of an automated system for pouring concrete, the trend of patent applications by year, country and detailed technology was investigated. Related technologies were classified into screed automation, CPB automation, and concrete pouring integrated system to analyze patent application trends. As a result, since 1999, patent applications have been steadily in progress, repeating increases and decreases in Japan, Korea, the United States, and Europe. In addition, the growth stage of the market is in the early stages of maturity, and patent applications for related technologies are expected to continue. In the future, based on the patent application trend analyzed in this study, the development direction of the automated concrete pouring system will be reviewed and the redundancy of similar technologies will be reviewed.

This research aimed to investigate the current trends of rooftop greening techniques of frequent use within and without Korea. It is also expected that this research will help developing new rooftop greening techniques appropriate for Korean environment. Data for this study have been collected from patent applications for rooftop greening techniques; the web sites of the Korean Intellectual Property Office as well as patent offices in Germany and Japan, where active researches on rooftop greening techniques are in progress. 168 applications within a period from the year of 1984 to December of 2004 were examined, among which Japan excelled with its 81 applications followed by Germany(54), Korea(31)and USA(2). In case of Japan, where more patent applications were found than in any other countries, applications for Plant Base(38) excelled others - System(36), Management(4) and Plant(3) in the number of applications. As for Germany, 25 cases were on Plant Base, 25 cases on System, and 4 cases on Plant; in Korea, 15 cases were on Plant Base, 11 cases on System, 3 cases on Plant and 2 cases on Management; in USA, 1 cases were on System and 1 cases on Plant. Overall, the total number of patent applications in three countries reaches 168 cases; among which Plant Base topped in all four countries, followed by 73 cases on System. Applications concerning Plant and Management totalled to 11 and 6 for each. In conclusion, most patents were concentrated on Plant Base and System while researches on Plant and Management still do not get as much attention as they deserve. Research and development of various techniques on Plant must be a precondition for the formation of diverse Bio-tops suitable for the environments of specific areas. Concrete researches on rooftop greening techniques will contribute to the improvement of urban ecosystem by developing more convenient and easily applicable techniques during the time of actual construction.
