본 논문은 세정기의 세척수를 인체에 유익한 자화육각수로 변환시켜주는 기술로서, 세정기로 세척수가 공급되는 유입 관에 자화기를 설치하여 세척수를 인체에 유익한 자화육각수로 변환시켜 사용함에 따라 비데와 변기를 위생적으로 유지 관리하게 해주는 자화육각수 제조 기술에 관련하여 특허를 시계열분석을 통하여 출원이 많은 대표적인 국가별 출원을 분석하였다. 자화육각수 제조 기술 분야의 특허 출원 동향을 살펴보면 대부분 한국과 일본에 의한 특허 출원임을 알 수 있으며, 일본특허는 특허건수와 출원인수가 모두 증가하는 발전기에서 특허건수와 출원인수가 모두 감소하는 퇴조기 단계에 있는 것으로 나타나고 있으며, 미국 및 유럽특허에서는 대체적으로 출원인수와 특허건수가 감소하는 퇴조기 양상으로. 분석 되었다. 따라서 자화육각수를 활용하는 사업에서는 특허 권리차원에서 한국과 일본특허의 출원 동향을 지속적으로 관찰 할 필요가 있으며, 그리고 현재 자화육각수기술은 사업전략구상과 산업지원정책수립이 필요한 단계에 있다. 따라서 향후 자화육각수관련 제품의 연구개발이 다수 예상됨에 따라 관련제조업체나 연구기관에서는 사업화와 특허연구에 유용하게 활용될 수 있을 것이다.

This study investgates Korean water technology through the water market perspective and analyses its competitiveness. Based on the water technology classification, water technology competitiveness is analysed through the technological influence index and market dominance index which are based on the extracted water technology patents from the US, Europe, Korea, and Japan for the last decade. As a result, the Korean water technology patents were lack in influence and competitiveness in global market considering the large volume of patents. There are two most tech-influential industries in Korea; manufacturing industry consisting pipes, sterilization, disinfection, and advanced water purification equipment, and construction industry including seawater desalination and water resource development. Due to the domestic usage of the patents, the Korean water technology patents scored low in global market PFS(Patent Family Size) index compared to their CPP(Cites Per Patent) index. The study is meaningful in a way that the analysis on Korean water technology competitiveness using water technology classification system and patent analysis was conducted based on the perspective of the global water market.

This study for the development of water purification Artificial floating island maximizing domestic Artificial floating island patent trends and product development, according to the timing of patent registration was analyzed for trends. In addition, domestic invention patent technology Artificial floating island typed according to the purpose and characteristics of domestic patents were Artificial Floating Island. In particular, domestic leisure space with a growing population and the need for securing emerging role as a reservoir of water only in the past, who do appeal as a tourist destination or as an ecological space utilized, and accordingly will transform and the need to secure a hydrophilic, degrade water quality problems using this aquatic environment (water acquisition and hydrophilic), the requirements are a big obstacle is the reality factor. This patented product differentiation strategy through the analysis of the development of technology progressiveness (Field Application) in terms of water quality improvement and maintenance side, and the hydrophilic side scenery, ecological restoration aspects, and applicability to the field and taking into account existing technology economic aspects of distinction were presented and advertised a lot in terms of cost compared to other techniques without the use of highly efficient methodology for building a water purification and also appears identity appeal, wetlands, rivers, etc. can be applied broadly technician widespread deployment and installation time to less simple and more are expected to spread.

본 연구에서는 기후변화 대응의 관점에서 미국 지하수 기술을 특허 네트워크분석을 통해 핵심특허를 파악 할 수 있었다. 분석된 핵심 특허를 살펴보면, 오염된 지하수를 중금속 제거기술을 사용하여 지하수가 오염되지 않게 하여 음용수와 오염 지하수 문제를 해결할 수 있는 방법으로 높은 영향력을 보였고 기술 간 전파 되고 있었다. 또한 지하수 기술 특허 간의 특허들이 매개역할을 담당하고 있었지만 지하수 기술 간의 특허의 연결성은 높지 않게 나타나고 있다. 지하수 관련 특허 기술은 크게 양수, 모니터링, 오염정화로 구분이 가능하였다. 모니터링은 지하수 유량, 흐름 또는 수질 분석을 위한 지표, 지리적인 특성뿐만 아니라 오염물질의 종류, 농도 등 물리화학 및 생물학적 특성 파악을 가능하게 하는 기술을 포함한다. 오염정화 기술은 토양 및 지하수 정화를 위한 원위치 또는 비원위치에 적용된 물리화학적 및 생물학적 정화 처리 공정을 말한다. 미국의 기술적 사례를 발굴하여 분석하면서 미국이 수처리 분야에서 기술력이 높았고 기후변화로 인한 물부족 문제에 대응하기 위해서는 이러한 기술진흥과 특허를 통한 지재권보호도 필요한 것으로 보인다.

Objectives : The purpose of this study is to present trends and contents of herbal Korean Medicine patches by analyzing the herbal patches in Korean patents. Methods : Electronic search for herbal patch patents was conducted in KIPRIS (Korea Intellectual Property Rights Information Service). Korean patents that were registered by January 1, 2018 were selected in study. Patents that were not using herbal medicine or not related to patch were excluded in this study. The applicant, application date, International Patent Classification (IPC), contents and adhesive site of patches, target diseases, model of experiment and extraction methods were analyzed. Results : A total of 17 patents were included in this study. In applicant analysis, 61.5% of applicants were corporations. All IPCs in patents were involved in Section A (Human necessities & Agriculture) and 66.7% of IPCs were A61K (Preparations formedical, dental, ortoiletpurposes). In types of patch, 8 patents were hydrogel patches (47.1%), followed by 3 heating patches (17.6%). Skin related symptoms were the most targeted diseases (52.9%), Human was the most used model in experiments. Solvent extraction and hot water extraction were used frequently, and some patents had no limit for extraction were also existed. Conclusions : The study results will be helpful to diversify formulation of herbal medicine, to expand market scale of patent and to develop new application using Korean medicine. In order to establish sufficient data for utilizing patent technologies, more patent studies providing analyzed patent information are needed.

Objectives : The purpose of this study was to analyze the trend of pharmacopuncture in Korean patent in order to establish database for patent technology. Methods : Electronic literature searches for Korean patents related to pharmacopuncture were performed in two electronic databases (Korea Intellectual Property Right Information Service and National Digital Science Library) to June 2017. Patents that were not Korean ones, did not use medicinal herb, only described method of manufacture, or had nothing to do with pharmacopuncture were excluded in this study. The status and application date of patents, Medicinal herb, target diseases, International Patent Classification (IPC), model of experiment and extracting methods were analyzed. Results : A total of 379 patents were retrieved. Based on our inclusion/exclusion criteria, 297 patents were excluded. Of 82 included patents, 27 patents did not include experiments using pharmacopuncture, and 9 patents were invented for treating animals such as pig or calf. In IPC analysis, Bee Venom, Panax (ginseng), Angelica, and Paeoniaceae were used frequently. Musculoskeletal diseases were the most targeted diseases followed by nervous diseases. For extracting, hot water extraction, distillation extraction, and solvent extraction using alcohol, ethanol, or methanol for solvent were commonly used. Conclusions : These data are useful for inventing new patent and extending range of pharmacopuncture in clinical use, however, more systematically analyzed patent studies and pharmacopuncture-related studies for new application on various diseases are needed in further studies.
