Valuing environmental patents legal protection when data is not available
This paper aims at estimating the value of legal patent protection of environment-related technologies, using the real options approach. In particular, we manage to overcome the problem of the lack of data for those countries that do not collect patent renewal data. Following this estimation strategy, we rank the value of legal patent protection for seventeen countries, closely reproducing other rankings based on surveys, for instance the PatVal survey by the EU Commission (2006), but relying on macro data publicly available and easy to access. The unit value of damage is found to be the most important determinant of the value of patents granted by legal protection.
