Abstract: Patents and their renewals are critical because they protect inventions and reinforce information reported to investors about the utility and the quality of inventions. Thus, they signal the appropriate use of financial resources being invested, notably in research and development departments, and future revenues for their owner. Based on a sample of about 22,700 European patents, our research contributes to existing literature on patent renewal by two relevant outcomes. The first contribution proposes a possible definition of a European patent life cycle: abandonment of procedure, natural abandonment, and late withdrawal. The second contribution shows two main factors that influence the renewal of a European patent by examining delivery time and the cumulative number of citations.
