Linkage between agency-supported research and patented industrial technology

CHI Research's early work on the citation linkage between patented technology in the USA, and the underlying research science base using 1987/88 US patents has been massively expanded to include citations from 1993/94 US patents, and an analysis of the cited US papers and the agencies supporting them. There is a very strong within-country component to the linkage: inventors in the US system cite their own country's papers approximately three times as often as would be expected, when adjusted for the size of the country's science. The linkage is strongest in the highly scientific areas of technology, and is quite subject specific. Over the six years separating the studies, there has been a remarkable three-fold increase in linkage. A large fraction of these papers cited in patents originate in the US university system, and are supported by US research support agencies. Copyright , Beech Tree Publishing.
