Firms' global patent strategies in an emerging technology

Despite international patenting can be a costly and risky investment, an increasing number of firms patent proprietary technologies in foreign countries. This paper explores trends of global patenting in a new domain of technology characterized by rapid globalization. The research setting consists of the population of U.S.-based Large and Small and Mid-Sized firms (SMEs) filing nanotechnology-related patent applications at the World International Patent Office (WIPO) during 1996-2006.
