Abstract

This study aims at analyzing the convergence of Internet-of-Things and wearables technologies using cooperative patent classification(CPC). CPC, introduced to an increasing number of technological fields of Korean patents, is expected to be widely used in Patent Informatics because the classification codes in CPC are more specific than those of IPC, which reflect the characteristics of technologies in detail with accuracy. CPC has seldom been used up to date and most of the previous researches on technological convergence used IPC. As a pre-analysis step for analyzing the trend of technological convergence of IoT and wearables, CPC and IPC codes assigned to each patent were compared. By applying association rule mining to the analysis of CPC codes, we identified the technological fields where convergence frequently takes place and examined the trend of technological convergence over time.

본 연구는 협력적특허분류(CPC)를 활용한 '사물인터넷(IoT)' 과 '웨어러블(wearables)' 의 기술융합동향 분석에 관한 것이다. 국내 도입 분야가 점차 확대되고 있는 CPC는 기존의 국제특허분류(IPC)보다 세분화된 분류를 제공해 기술 특성을 더 세밀하고 정확하게 반영할 수 있어 특허정보 분석 시 활용도를 배가시킬 것으로 기대된다. 아직까지 CPC를 특허정보 분석에 활용한 연구가 드물며, 특허분류코드를 활용해 기술융합현상을 분석한 선행연구들 대부분이 IPC코드를 활용하였다. 본 연구에서는 CPC를 활용하여 wearable IoT 영역의 기술융합동향분석을 실시하였고, 이를 위한 사전분석으로서 각 특허에 할당된 CPC와 IPC를 비교분석하였다. 연관규칙 마이닝 기법을 활용한 CPC 코드분석을 통해 융합이 활발하게 발생하는 기술영역들을 도출하고 시간에 따른 추세변화를 파악하였다.
