There are several methods for the hydrogen production such as steam reforming of natural gas, photochemical method, biological method, electrolysis and thermochemical method, etc. These days it has been widely studied for the hydrogen production method having low hydrogen production cost and high efficiency. In this paper, patents in the hydrogen production by steam reforming of natural gas were gathered and analyzed. The search range was limited in the open patents of USA(US), European Union(EP), Japan(JP), and Korea(KR) from 1996 to 2006. Patents were gathered by using key-words searching and extracted by filtering criteria. The trends of the patents was analyzed by the years, countries, companies, and technologies.

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.

This study investigates the determinants of output of a manufacturing firm's innovative activity (the number of patent applications) and spillover effects using a count data model. This paper attempted a negative binomial distribution In order to take into account unobserved heterogeneity. The results of our study suggested that Firm size, R&D intensity, technical network activity, and online business performance have significantly positive effects in the Korean manufacturing industry. Moreover, there are significantly positive spillover effects in the same industry sector.

The explosion in creation and utilization of IP including Patent since 1980s has been regarded as typical trend affecting the environment for technological innovation. Korea also has shown massive creation of IP. These stimulate the focused interest on the effectiveness of IP for protecting the innovation output. We try to analyze the determinants of this effectiveness in Korean manufacturing sector in terms of the charactenstics of firm's innovation strategy. It is shown that, for protection for product innovation, as being larger, and as having made innovation, the IP protection is regarded as effective, and firms making cooperative R&D have a higher possibility of using IP protection. And larger firms give a higher recognition to effectiveness of IP protection irrespective of the types of innovation such as product innovation and process innovation.

There are several methods for the hydrogen production such as steam reforming of natural gas, photocatalytic method, biological method, electrolysis and thermochemical method, etc. These days it has been widely studying for the hydrogen production method having low hydrogen production cost and high efficiency. In this paper, patents in the hydrogen production by water electrolysis were gathered and analyzed. The search range was limited in the open patents of USA(US), European Union(EP), Japan(JP), and Korea(KR) from 1996 to 2005. Patents were gathered by using key-words searching and filtered by filtering criteria. The trends of the patents was analyzed by the years, countries, companies, and technologies.

This paper starts out by reviewing the literature that in different ways utilizes patent data as an output of Research ＆ Development (R&D) investment. The main focus, however, is an analysis of time-lag between industrial R&D input and its output. To achieve this research's purpose, the basic data associated with the industrial R&D input (expenditure, researchers) and output (applied patent and utilities) for the past 15 years, from 1980 to 1994, in the areas of electrical-electronic, mechanical and chemical industries have been collected. And the raw input data were altered into real flow data (but stock data) using Laspeyres approach and analyzed using multiple regression analysis, especially stepwise regression analysis. The result of this study can be summarized as follows: a) The time-lag; between industrial R&D input and its output is within 1 to 3 years. b) The time-lag: of patents was longer than that of utility models. c) The time-lag: in electrical-electronic, chemical industry was longer than that of the mechanical industry.

Radiopharmaceuticals are constantly being studied in the field of tumor diagnosis and therapy. As a result, many patents have been registered related to the development of radiopharmaceutical therapy. In this study, effective patents related to radiology and nuclear medicine filed during the past 10 years were collected from various countries like Korea, United States, Japan, Europe etc., and the application trends and growth stages were analyzed through statistical analysis. From the analysis results of 47,991 patents related to radiology and nuclear medicine, only 6,268 registered patents were found valid, and 80% of those were related to radiopharmaceutical development. In addition, we analyzed the patent of major competitors and used them to analyze the trends in radioisotopes and medicinal research. Among these, all the top 10 major applicants have found to be concentrating on radiopharmaceutical development.

With the advance to the knowledge-based economy, science and technology (S&T) has been recognized as key factor in a nation's competitiveness. To cope with this kind of new trend Korean government has tried to increase the R&D investment and to streamline acts and regulations concerning national R&D activities. Korea's total R&D expenditure for the year 2007 amounted to about 31.3 trillion won including government R&D of 8.9trillion won. With these efforts the capacity of Korea S&T has made great strides recently. Korea was ranked world's top 7 in R&D investment, top 12 in S&T paper publication and top 4 in patent application. Korean government enacted several pieces of legislation concerning S&T : the "Technology Transfer Promotion Act (1999)"; the "Framework Act on Science and Technology (2000)"; and the "Presidential Regulation for Managing the Government R&D Programs (2001)." In addition, the government has put a lot of effort into promoting the commercialization of technologies developed in public sector and improving the infrastructure of technology transfer and commercialization. However in spite of these various efforts, the technologies obtained from the public sector have not been transferred to the industry properly. Only 24.2% of technologies developed in the public for the year 2005 were transferred to industry. The royalty revenues of the public for the year 2005 was 1.5% of their total R&D expenditure. It shows only a third of the percentage of royalty revenues for the public sector in the U.S.A. and a second of Europe. There are many obstacles of public technology transfer such as immaturity of technology market, lack of licensing experience, and inadequacy of legal system and government policy. In this study I compared the Korean legislative system of patent management of government R&D outputs with the American system, derived problems from Korean system, and suggested proper alternatives.
