A Dynamic Analysis of University Ag-Biotech Patent Production

Abstract

This paper examines the factors that account for ag-biotech patenting success among universities using a dynamic count data model. It builds a theoretical and econometric model to capture the inherently dynamic and nonlinear process of technological innovation, wherein a feedback mechanism from previous success partially determines current patent counts. The econometric estimates reveal the importance to ag-biotech patent production of land grant infrastructure, quality faculty, patent-oriented technology transfer offices, as well as dynamic feedback effects.

Trends in University Ag-Biotech Patent Production

Submitted to Review of Agricultural Economics, February 28, 2001

Abstract:

This work exploits information on U.S. patents to identify trends in university ag-biotech patenting and citation performance. It sets forth some key issues concerning patterns of university ag-biotech patenting and then provides an empirical analysis on the evolving trends. Land Grant Universities account for most U.S. ag-biotech patents. The data show a path dependent innovation pattern, in which there also seems to be a culture of patenting that develops at certain universities. Evidence shows that ag-biotech patents are more cited than the average university patent. Inequalities across Land Grant Universities are also evident in the production of ag-biotech patents, although perhaps not to a much greater degree than underlying inequalities in funding and research qualities. The paper closes by considering how the evidence offered might be used to advance the public discussion regarding trends in agricultural biotechnology research in the U.S.
