특허를 통한 교육 분야의 기술 추세 분석

Technological trends in a certain industry or technology field appear more clearly in patents. In this paper, we try to find the trends in the education field through patent analysis and estimate the development direction of education centering on the keywords obtained from the analysis. To this end, education-related patent data for the past 20 years applied to patent offices in Korea, the United States, and China were collected, and technology rise, technical competition intensity, and technology strength were analyzed. In addition, frequent keywords were found from the names of patents, and technological trends of patents in the education field were analyzed from the relationship between them. Apriori algorithm was used for keyword analysis. As a result, due to the nature of the field, there was no rapid change in the number of applications, and it was found that the market was in a state of relatively perfect competition and that the United States have technological leadership. Furthermore, service-related patents that provide educational contents are at the center, and based on this, under the influence of the 4th industrial revolution, it is understood that keywords such as intelligent, online, cloud, data, platform, big, information are related and applied for patent. Unlike other fields, the education field does not have many patent applications, so it is judged that more useful implications could be obtained if the analysis was expanded to include intellectual property rights such as trademarks, utility models, or designs.
