| Abstract: | The aim of this article is to develop new patent indicators for evaluating technological innovation competitiveness between
companies. A novel indicator representing an industrial’s patent performance, Essential Patent Index (EPI), was developed
by incorporating information on who cited these patents and when these patents were cited, based on the assumption that both
contribute to meaningful quality assessment. By combining EPI and Chi’s well known Technological Strength (TS) indicator,
a second novel indicator Essential Technological Strength (ETS) was developed to represent the innovation competitiveness
of an individual company. In this study, patent performance of three high-tech industries in Taiwan were analyzed using ETS
as well as the traditional TS for comparison. Results from this analysis demonstrated that ETS provided better insights by
clearly verifying the latent influence of citations, reinforcing the impact of essential patents, and aggrandizing the differences
of innovation competitiveness between companies. |
