Title: Heterogeneity of Intellectual Assets
An Empirically Based Research Method for Identification and Measurement Using Patent Data
Author: Dahlgren, Henrich; Lund Jensen, Rasmus; Valentin, Finn
Abstract: This paper deals with methodological issues of assessing the composition and level of heterogeneity of firms’ intellectual assets. It develops an original metric - referred to as the H-index - for measuring heterogeneity using data extracted from patent documents. The main purpose is to improve the characterisation of research activities within firms in the biotechnology sector. Although the H-index grew out of research on biotech firms, the metric carries broader relevance for all patent-intensive industries. The measurement and calculation of the H-index is illustrated using some empirical examples from our preliminary study on Scandinavian biotech firms.
