This paper provides novel theoretical and empirical contributions on how patent scope varies over time and by type of applicants in the initial phases of an emerging technology. We refer to the literature on technology life-cycles and on appropriability regimes to study the evolution of patent scope - as measured by the number of claims - in the specific case of nanotechnology. Our regression analyses based on a sample of 58244 nanotech US patents show that - once controlling for time, sector and firm effects - patent scope decreases over the subsequent phases of the technology life-cycle. We conclude by discussing the managerial and policy implications of our results.

Abstract

This paper provides novel theoretical and empirical contributions on how patent scope varies over time and by type of applicants in the initial phases of an emerging technology. We refer to the literature on technology life-cycles and on appropriability regimes to study the evolution of patent scope - as measured by the number of claims - in the specific case of nanotechnology. Our regression analyses based on a sample of 58244 nanotech US patents show that - once controlling for time, sector and firm effects - patent scope decreases over the subsequent phases of the technology life-cycle. We conclude by discussing the managerial and policy implications of our results.
