Abstract

In this paper, we investigated the number of domestic patent applications by year, the number of domestic patent disclosures by year, and the number of domestic registrations by year regarding smart factories. The number of patent applications by applicant type was investigated. Based on the patents studied, it was found that the IPC appearing in the most patents was G05B 19/418. In addition, through social network analysis of smart factory patented IPCs, it was found that G05B 19/418 was the IPC with the highest degree of centrality. From the above, if the IPC of the core technology of the patent submitted for smart factory is G05B 19/418, the technology combined with G05B 23/02, that is, the technology combining "factory control" and "monitoring" is the most patented. When the IPC of the core technology was G06Q 50/04, it was confirmed that the technology combined with G06Q 50/10, that is, the technology combining "manufacturing" and "service" was the most applied for patents. Through this, it was found that in order to apply for a patent for a smart factory, it would be necessary to file a patent application that takes into account the connectivity between IPCs.

본 논문에서는 스마트공장에 관한 연도별 국내 특허 출원 건수, 연도별 국내 특허 공개 건수 및 연도별 국내 등록 건수를 조사하였고, 출원인 유형별 특허 출원 건수를 조사하였다. 조사된 특허를 기반으로 가장 많은 특허에서 나타나는 IPC는 G05B 19/418이라는 것을 밝혀냈다. 또한 스마트공장 특허 IPC의 사회 연결망 분석을 통해 G05B 19/418이 연결중심성이 가장 높은 IPC임을 밝혀냈다. 이상의 내용을 통해 스마트공장으로 제출된 특허의 핵심기술의 IPC가 G05B 19/418일 경우, G05B 23/02와 조합된 기술 즉, "공장 제어"와 "모니터링"이 복합된 기술이 특허로 가장 많이 출원되었다는 것과 핵심기술의 IPC가 G06Q 50/04일 경우, G06Q 50/10과 조합된 기술 즉, "제조"와 "서비스"가 복합된 기술이 특허로 가장 많이 출원되었다는 것을 확인할 수 있었다. 이를 통해 스마트공장으로 특허를 출원하기 위해서는 이러한 IPC간의 연결성 고려한 특허출원이 필요한 것을 알 수 있었다.
