Improving patent valuations for management purposes--validating new indicators by analyzing application rationales

This paper analyzes the validity of so-far untested indicators of patent value to enhance the quality of patent assessments using indicators at the corporate level. The article expands the theory by eliciting patent attorneys' filing rationales to maximize profits from protecting intellectual property, to inspire the computation of new value indicators, including patent full-texts. Then, based on a newly compiled data set consisting of 813 EP patents, the probability of an opposition against a patent is modeled by established and new value indicators. The results show that accelerated examination requests and qualified word counts enhance the quality of existing valuation methods. [PUBLICATION ABSTRACT]
