Hydrogen storage is widely recognized as a critical enabling technology for the successful commercialization. There are a few different approaches for hydrogen storage technology. In this paper, characteristics of hydrogen storage technologies were analyzed from the literature survey. Also, The technology trend of hydrogen production was scrutinized based on patent analysis. In patent analysis the search range was limited to the open patents issued from 1996 to 2006. The technology trend of hydrogen storage was assessed by classifying each patent based on the publishing year, country, and the type of storage technology.

The Schizandra chinensis (Korean name : omija) is a fruit native to northeast Asia that is cultivated in South Korea and China. Using 1,938 valid patents of 6 group countries, we analyzed the patent trend based on year, countries, applicants, and technology. The technologies are categorized the 10 sub-technologies such as medicine, quasi-drugs, food, feed, cosmetics, cultivation, genome, manufacture, preprocessing, and etc. The technology level and competitiveness are analyzed using patent index such as cites per patent, patent impact index, patent family size and technology strength. In Korea, patent number rapidly increasing and individual technical level is lower than other countries. However, overall technical competitiveness is estimated high due to multiple patents. We suggest that cosmetics and cultivation fields are most likely to be developed in future omiza technology development in Korea. Our study will provides to the information of technical trend to support performing of new projects for omija plant.

This study analyses patent information of apparel design using computer technology and researches the trend of patent application focused on International Patent Classification. In terms of trend by filling data, Patent application started first in 1974 and increased sharply in 1993 with 14 cases and increased to 25 cases in 2000. In case of Korea, they began somewhat late in 1996, but reached a similar level with the leading country in 2000. In terms of trend by applicant, Gerber Garment Technology, Inc. filed 7 cases TORAY IND INC, filed 6 cases Levi Strauss & Co. filed 4 cases, NEC HOME ELECTRONICS LTD filed 3 cases, TOYOBO CO LTD filed 3 cases. Japanese companies occupied 52% and United States's companies occupied 48%. In terms of trend by country, foreigner occupied 47% of the patents filed by United State. Japanese take up 10% of total patent of United States. Korean occupied 84% of total patent of Korea and foreigner, american occupied 16% of the patents filed by Korea. In regared to International Patent Classification, in the section level G filed 92 cases(53%). In class level, G06 marked the first place in United States, Japan, and Korea. In subclass level, G06F marksed the first place with 74 cases. G06T and A61B were regarded as the new technologies. The new technologies are representing the dimensions of garment or computer-rendered model, providing the virtual reality through the texture mapping, digital dressing room or virtual dressing, and performing or retriving display on a screen for the result of changing pattern ao dress design, The technologies of core patent are designing or producing custom manufactured item, providing or prealtering the data for pattern making and visually displaying, interactively generating or previewing of various articles.

This study investigate the patent trend of natural feed additives for avian influenza prevention and immunity enhancement. The search scope is Korean and Chinese patents published before December 31, 2017. As a result, I found 53 Korean patents and 105 Chinese patents. Korea and China has increased the number of patent applications since late 2000. In particular, China filed the most patent applications in 2016. Both Korea and China, the oriental medicine materials were mainly used in patent claims. Korea has many patent applications that are submitted by universities, research institutes and bio companies, but China has a high proportion of individual patent applicants.

The purpose of this study was to analyze the patent application trend in the processing technology for medicinal herbs. Recently, in processing technology for medicinal herbs, experimental researches have frequently been published through papers in journals. However, the research results about the patent area were fewer than the others. We tried to analyze the patent application trend in nonthermal processing technologies for medicinal herbs by country as Korea, Japan, U.S.A. and Europe. The detailed technologies consisted of pulsed electric field, oscillatory magnetic field, intense pulsed light, ultrasonification, high hydrostatic pressure, microwave, radiation, Ohmic heating, and supercritical extraction. As a result we found that patents of nonthermal processing technologies has been growing steadily in quantity from 1980s and growing quickly since 2000s. The number of patent in Korea is larger than others as making up 70% in that whole. The number of patent in ultrasonification field was larger than others in portfolio analysis. Patent application trend in nonthermal processing technologies for ingestion occupies high share compared to other usage applications. In conclusion, patent trends of nonthermal processing technologies for medicinal herbs belong to the period in the development.

Hydrogen is clean and renewable and is recognized as a very promising energy to solve both depletion of petroleum resource and environmental problems caused by use of fossil fuels. Extensive researches have been performed worldwide on the production technologies of hydrogen. In this paper, characteristics of hydrogen production technologies were analyzed from the literature survey. Also, The technology trend of hydrogen production was scrutinized based on patent analysis. In patent analysis the search range was limited to the open patents issued from 1996 to 2005. Patents were gathered by using the key-words searching method and filtered by desirable filtering criteria. The technology trend of hydrogen production was discussed by classifying each patent based on the publishing year, country, and company, and the type of production technology.
