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. |
