Abstract
One of the most difficult challenges in technology transfer is to measure the movement of knowledge from basic scientific research to industrial technology. This paper will report on a study of the linkage between science supported by the Agricultural Research Service (ARS) and patented technology. This study traced the citations from U.S. patents issued in 1987–88 and 1993–94 to scientific research papers linked to the U.S. Department of Agriculture (USDA). The number of patent citations to ARS papers, and to other USDA-supported papers has increased fourfold over the six-year period. A distinct difference also exists between the patent-cited ARS papers and patent-cited extramural USDA-supported papers: ARS papers are in more agriculturally related journals, while the extramural papers were in more basic and biomedical journals. USDA-supported papers were overwhelmingly cited by U.S.-invented patents (in a patent system in which half the patents are foreign-invented). In the primary field of ARS papers (Biology), they are cited much more often by patents than Biology papers from any other publishing organization. Since the publishing organizations and support sources of all the papers cited in these patents have now been identified, we can study the transfer of scientific results to patented technology by institution, by agency, or by any other category of patent or paper holder.
