Abstract

This study aims to analyze the technology lifecycle from the perspective of the dynamics of patent characteristics; the dynamics of patent characteristics are proposed as an approach for characterizing technology lifecycle in this study. DVD and hard drive technologies, which have already experienced their complete technology lifecycles, were selected for analyzing their patent characteristics as a function of the different stages of their technology lifecycles to thus obtain the objective of this research. The results obtained in this study provide a channel to assess the nature of firms’ innovation strategies along technology lifecycles. It can be observed that (1) patents attempt to cite more prior patent or non-patent references at the latter stages to find more technological or scientific sources that can contribute to technological innovation, (2) most litigated patents are granted in the Growth stage, so it is expected that patents in the Growth stage should be more important and, thus, more relevant to dominant design than the patents granted in other stages.
