국방R&D의 혁신결과 분석 -ADD 특허의 후방 인용자료를 이용하여-

This paper analyzes inventions made by R&D efforts done by ADD(Agency for Defense Development), a military R&D branch using backward-citations. The findings are as follows. ⅰ) The number of patent claims is positively correlated with the dependency of prior knowledge, originality, and technological distance. ⅱ) Both at the inventor level and at the organization level, research cooperation decreases the number of backward citations. A co-invented patent cites older sources compared with a patent made by a standalone inventor. Patents made through research cooperation between organizations is based on a relatively narrower scope of knowledge compared with those made through separate research. ⅲ) The larger is the size of a inventor team, the more non-patent sources and the younger patents are cited by the team, ⅳ) A patent on which a prolific inventor is listed cites less. ⅴ) The citation of foreign patents are positively correlated with the total number of backward citations, and negatively correlated with non-patent citations and originality. A patent including the citations of foreign patents draws from younger sources and has low appropriability.
