World Patent Information, 1990, vol. 12, issue 2, 89-94

Abstract: Using a database built on company patenting in the U.S., the Authors examine the scale and distribution of the technological activities of the world's largest manufacturing firms. The relative importance of large firms in the world's technology is analysed to determine their share of the world total in 32 technical areas, their share of total technological activities and the internationalization of technical activities.
