Abstract

In order to make a decision about the acquisition of command control communication weapon systems considering the client's technology level requirements, the improvement of the domestic technology level and security of core technology, the person in charge can perform technology evaluation/analysis based on command control communication weapon system patent data. As a method of collecting such patent data, we can collect the patent data of government-designated (Defense Acquisition Program Act Article 35) companies (11 Major defense companies/9 General defense companies) through the Korea Intellectual Property Rights Information System (KIPRIS) of the Korean Intellectual Property Office (KIPO) In this way, we collected 1,526 patents and 134 International Patent Classification (IPC) types through the KIPRIS of the KIPO. Based on these data, we performed three types of analysis, General information analysis, Principal Components Analysis (PCA) and Network analysis, and extracted 27, 19 and 13 IPC types from them, respectively. Based on the above three analysis results, we confirmed 8 IPC types (F41A, F41G, G06F, G01S, H04B, H04L, H04M and H04W) as the key technologies and representative technology fields of domestic communication-electronics defense companies.

고객이 요구하는 지휘통제 통신무기체계 기술 수준 요구와 무기체계 개발을 통한 국내 기술 수준 향상 및 핵심기술 확보가 필요하다. 이러한 무기체계 획득 방향을 고려한 의사결정으로 국내 지휘통제 통신무기체계 방산업체 특허 자료를 기반으로 기술분석/평가를 수행/활용 할 수 있다. 지휘통제 통신무기체계 관련 방산업체의 특허 자료 수집 방법은 방위사업법 제35조(방산업체의 지정등)에 따라 지정된 11개 주요방산업체와 9개 일반방산업체의 특허자료를 특허청 특허정보검색서비스를 통해 수집할 수 있다. 수집된 전체 특허/국제특허분류 수는 1,526건/134개이며, 통신전자 방산업체 특허자료 일반정보 분석 결과 평균 11.39개 이상 출원한 국제특허분류는 27개, 주성분 분석 결과 분산 평균 크기 10.01 이상 넘어가는 국제특허분류 19개, 네트워크 분석 결과 각 평균(연결중심성 : 58.42 / 근접중심성 : 93.44 / 매개중심성 : 2.02) 이상 넘어가는 국제특허분류 13개임을 확인했다. 본 분석 결과를 기반으로 공통으로 나타난 국제특허분류 8개(F41A, F41G, G06F, G01S, H04B, H04L, H04M, H04W)를 통해 국내 통신전자 분야 20개 방산업체 대표 기술 분야임을 확인했다.
