Patent quality determinants based on technology life cycle with special reference to solar-cell technology field

Abstract

The purpose of this study is to illustrate the necessity of considering the technology life cycle when creating a distinct R&D strategy planning, if the aim is to enhance patent quality. The study also suggests an effective R&D strategy for the solar- cell technology field. It uses count data models to introduce the concept of technology life cycle and analyses the determinants of patent quality that depend upon the technology life cycle. Empirical results show that three variables influence patent quality in contrary manners, depending on the stage of the technology life cycle. This means that an R&D strategy for each of the three variables should be established while considering the technology life cycle. As a result, this study clarifies that the technology life cycle needs to be considered when establishing an R&D strategy that will enhance patent quality, and it suggests that distinct R&D strategy planning should be done for the solar-cell technology field in particular while bearing in mind the technology life cycle.
