Abstract

With a sample of nearly 18,611 utility patents, this paper studies the technology mix of 90 of the world's leading food and beverage multinationals (FBMs) over 1969-1994. It explores the statistical association between patenting in food technology and in non-food technological fields. Food patenting is always associated with patenting in Biotech, Chemistry, Machinery and Other patenting, whatever the home country of the company. The strength of the association, however, could vary. Herfindahl indices show that capabilities in core technology and in Machinery and Other fields are spread among many FBMs. Though to a lesser extent, technical capabilities in Biotechnology, Packaging and Refrigeration are also dispersed. By contrast, patenting in Tobacco, Chemistry and Drugs is concentrated.
