자율주행차 기술의 산업 간 특성 차이에 대한 연구 - 자동차와 비자동차 산업 간의 비교를 중심으로 -

초록

This study analyzes 7,889 patents filed in the United States for differences and changes in industrial, technological, and dynamic characteristics of autonomous vehicle technology. In particular, we analyze application trends, industry concentration, convergence and applicability of technology, the number of inventors, marketability, and source of technology. We found that autonomous vehicle patents had increased rapidly since 2010, with the non-automobile industry growing faster than the automobile industry. While the automobile industry focused on vehicle control technology, non-automobile industry focused on communication technology. Patents are distributed more widely among different firms in the non-automobile than in the automobile industry. Whereas technological breadth is relatively narrow for the non-automobile industry, both the number of family patents and the number of non-patent citations were higher for the non-automobile industry than for the automobile industry. The number of inventors in the automobile industry was higher before 2010 but became lower after 2010. In sum, the non-automobile industry is ahead of the automobile industry in terms of originality, marketability, complexity, and size of technology, so that companies belonging to the non-automobile industry are likely to play a significant role in the autonomous vehicle technology the future.
