Abstract

Using U.S. patent records in nanotechnoloy, we study the impact of university research on industry innovations with the premise that knowledge is diffused from universities to industry via personnel with university research experience. Appearing on a patent assigned to a university is evidence that an inventor has been exposed to university research, either directly as a university researcher or through some from of collaboration with university researchers. Over the period 1985-97, we find a steady increase in industry's employment of inventors with university research experience. In the 1990s we find the productivity (in terms of patenting rates and patent quality) of inventors with university backgrounds begins to exceed the productivity of the inventors without such experience. We also find that the share of industry patents in nanotechnology that cite university-assigned patents almost doubles during the period and inventors with university experience cite mostly university patents not invented by them, implying that they are instrumental in transferring general knowledge created throughout the university community.
