This study analyzed the trends of patents for unmanned technology used in agriculture. The target countries for this survey of patent data were Korea, the USA and Japan as well as the countries in Europe. The indices used in this study to analyze the patents were the CPP (Cites Per Patent), PII (Patent Impact Index), and PFS (Patent Family Size). The total effective patents for unmanned technology used in agriculture were 1,080 cases. The number of patents in the USA, Japan, Europe, and Korea were 541, 326, 128 and 85 cases, respectively. Among the total effective patents, the evaluation scores for selected important patents were calculated by applying commonly used weights to each index, and the top 10 patents were selected as important patents. The results showed that all the top ten patents are owned by the United States and that the United States is an advanced country in the field of unmanned technology used in agriculture. The evaluation score of the important patents using the existing method was biased toward the PII index among the three patent evaluation standards, and the effects of the number of claims and the PFS were relatively small. Therefore, a reliable patent analysis in the field of unmanned technology used in agriculture needs to reflect the overall evaluation factors taking into consideration the scope of the evaluation factors.

The purpose of this study was to examine the current status of patents related to dietary life of the elderly in Korea. Using Korea Intellectual Property Rights Information Service, patents registered between 2002 and 2013 were searched with the key words including 'elderly or the aged' and 'food, meal, or dietary life.' The search results showed 1,438 patents, and 500 patents meeting the research purpose were selected and analyzed. They were divided into two categories: 'patents on foods' and 'patents on products and services related to dietary life.' The former was further divided into four subgroups as follows: foods for health promotion, foods for disease prevention, foods for the people with difficulty in swallowing and masticating, and others. Also, the latter was divided into products or services. The results showed that patents on foods accounted for about 90%, of which the patents on foods for health promotion were ranked as the highest (40%). The number of patents on products and services related to dietary life was relatively small, indicating that the technology development has been focused on foods. Therefore, the technology for products and services related to dietary life should be actively developed as well as that for foods to improve the quality of life for the elderly in the future.

This study analyzed the current status of registered patents related to food tech in Korea and Japan. Using the patent information search services of Korean and Japanese Patent Offices, patents registered during the past 10 years from January 1, 2005 to December 31, 2015 were searched with the following key words/phrases: "food or meal or diet" and "program or information system". A total of 669 patents (539 for Korea and 130 for Japan) were finally selected and analyzed. Based on Porter's value chain theory, the patents were categorized into three dimensions related to "manufacturing/processing/distribution", "sales & marketing", and "consumer support". The results showed that in Korea, 41.7% of the total patents were related to sales & marketing followed by consumer support (37.3%) and manufacturing/processing/distribution (21.0%). In Japan, patents related to consumer support accounted for 56.2% followed by manufacturing/processing/distribution (32.3%), and sales & marketing (11.5%). In the area of manufacturing/processing/distribution, "food quality management system" in Korea, and "food manufacturing and processing management system" and "food safety control and hazard analysis system" in Japan tended to show a significantly higher proportion of patents registered (p<.05). Under sales & marketing, patents in the categories of "food purchase and delivery service system" in Korea and "restaurant information sharing system" in Japan tended to be more frequently registered (p<.05). Finally, in the area of consumer support, "kitchen facility and cooking device control system" in Korea and "menu and nutrition management system" in Japan tended to account for a significantly higher proportion of patents registered (p<.001). The results are expected to provide useful insights into the development of new patents and markets for food tech in the future.

본 논문은 대학의 연구활동을 특허라는 창을 통하여 들여다보고자 하였다. 특허인용정보가 있는 미국 특허를 이용하여 우리나라의 대학 특허를 기업 특허와 대비시켜 대학 특허의 특성을 분석하였다. 일반적으로 기업 특허와 대학 특허는 전자는 전유성(appropriability) 측면에서 그리고 후자는 기초성(basicness) 측면에서 차이가 있는 것으로 본다. 그런데 기초성 측면에서 우리나라 대학 특허는 기업 특허와 크게 두드러진 차이를 보이지 않는 것으로 나타났다. 다음으로 특허인용함수모형을 이용하여 특허의 질 또는 수준을 기업과 대학 사이에 비교해 보았다. 기업 특허는 자체인용이 상당수 포함되어 있는데, 이를 감안하면 전방인용에 있어서는 대학 특허와 기업 특허는 큰 차이를 보이지 않는 것으로 나타났다. 자체인용 비중이 높을수록 특허의 전유성 정도가 높은 경향이 있다는 선행연구를 상기하면, 기업 특허의 전유성 정도가 높게 나오는 것을 확인할 수도 있었다. 미국과 유럽을 대상으로 한 선행연구에서는 대학 특허가 대체로 기업 특허와 비교하여 인용빈도 측면에서 뒤지지 않는 것으로 분석되고 있다. 외국의 대학 특허 분석결과와 본 논문의 우리나라 대학 특허 분석결과를 대비시키면, 우리나라 대학 특허는 전반적인 수준이나 영향력 측면에서는 기업 특허에 미치지 못하며, 이는 우리나라대학의 특허활동이 최근에야 활성화된 데 기인한 것으로 추론된다. 이러한 분석 결과는 향후 대학의 연구수준을 제고하기 위한 노력을 보다 체계화해야 한다는 것을 시사하며, 최근 진행되고 있는 정부의 기초연구 정책방향 전환이나 대학 내의 자체적인 개혁 움직임을 간접적으로 지지한다. 정부의 정책 전환과 함께 학내의 개선 노력이 합치되면 향후 우리나라 대학의 특허인용도 및 영향력이 훨씬 높아지게 될 것으로 기대할 수 있다.

Aims: We have examined and analyzed trends of acupuncture related patents to understand the status of acupuncture technology and research trends of acupuncture in major countries including Korea, the United States, European Union and Japan. Methods: To analyze the patents, we searched and analyzed the total of 1,048 on-line DB based patents under time limit of July, 2006. Results: According to the search results, Korea is mostly superior compared to the others in number of domestic patents. However, Korea patents is inferior in number of international patents and leave much to be desired in industrial applications because of low patents barrier of personal patents and the absence of prospective clients. In addition, in this study, we show an index of international competitiveness and preliminary data of necessity of international cooperation in a field of acupuncture researches. Conclusion: These data suggest that Korea has strong possibility to recover competitiveness for guaranteeing valuable patents, if there are international cooperation and intensive managements of industries in advanced country markets.

Objective: In this study, we analyzed the trend of patents registered prior to October 4, 2019, to understand the industrial trends in insect-derived medicinal materials used for the treatment of skin diseases. Methods: Using the WIPSON database, we collected information regarding the patents related to insect-derived materials for treating various skin diseases. Results: The patents registered prior to October 4, 2019, from Korea, Japan, the USA, China, and the EU, along with those registered under PCT were selected. There were 195 patents related to the use of insect-derived medicinal materials in treating various skin diseases such as psoriasis, inflammatory skin diseases, eczema, pruritus, and atopic dermatitis. China is mostly superior in total number of registered patents compared with the other countries. Korea was the major patent technology-holder for atopic dermatitis, but China dominated in the remaining categories of skin diseases. Upon first patent registration in 1992, there had been a continual increase in the number of patents. Especially, patents related to eczema, psoriasis, inflammatory skin disease were markedly increased. Most frequently used insect-derived medicinal materials was Scolopendra, Cicadidae Periostracum, Scorpions, Cantharides, and Batryticatus Bombyx. The insect-derived medicinal materials were generally used as a combined preparation with other medicinal materials in patents. Conclusion: This study could help to establish the basis for future research and development related treating skin diseases using insect-derived medicinal materials. In order to provide sufficient data, further study including analysis of rejected patents is needed.
