초록

Developing and securing standard technology in mobile communication technology is one of the most important factors determining firm competitiveness. After collecting 23,879 mobile communication standard patents this study analyzes 88.8% of them which are owned by the top 16 companies. We analyze two quantitative indices such as patent share and growth rate and four technological quality indices such as forward citations, originality, self-citations, and the concentration of technology at both firm- and patent-level. Our analysis shows that Samsung and LG are technological leaders in quantity and scope, but not in quality, originality and open innovation orientation. Their patterns are a clear contrast with Apple. Qualcomm and Ericsson have built a well-balanced portfolio and are categorized as quality technology leaders. The results are generally supported at patent-level also as indicated by the results of regression analysis. This study vindicates practical usefulness of the suggested analytic framework in decrypting technology strategies of firms.
