Abstract:The value of patent as a real option has been examined in previous research, while the understandings on the pattern and process of patent option decision-making is relatively lacking. This study draws from real option theory and tries to reconstruct the various management decisions faced by companies in the investment and disposal of patent options. First, the study identifies and matches the traditional perspective of patent-level application, maintenance, and implementation decisions and the typical option decisions in real option logic. On this basis, the decision-making process model for option updating of patent portfolios is constructed. Finally, the impact of internal (organizational strategies and resources) and external factors (environmental uncertainty and option exclusivity) on the decision-making of patent portfolio renewal was discussed at the corporate level.
