Abstract

Patent metrics are increasingly used to assess the competitive position of technology-oriented firms. Patent rankings and patent scoreboards are popular methods to benchmark patent portfolios of firms against each other. Existing rankings, however, have methodological limitations that significantly reduce the meaningfulness of these benchmarks for managers, investors and other stakeholders. In this paper, we develop a new benchmarking methodology that overcomes limitations of existing approaches and offers a more accurate assessment of a firm's patent portfolio vis-à-vis its competitors. Firms are ranked according to the Patent Asset Index, which is derived from a set of newly developed patent indicators. These indicators are empirically validated and reflect more accurately the value of patents. We apply the new benchmarking method in the global chemical industry and contrast our findings with those of other existing patent portfolio rankings.
