Linkage between patents and papers: an interim EPO/US comparison

摘要

A unification of more than one million non-patent references (NPR's) on the front pages of U.S. and EPO patents has been carried out, with a subsequent match to the Science Citation Index (SCI), in order to investigate the citation linkage between patented technology and the Scientific research literature. The U.S. system shows an extremely rapid increase in linkage, with Citations from U.S. patents to U.S. authored papers increasing more than three-fold over the last Decade. The EPO system does not show nay increase; the occurrence of non-patent references Appears to be relatively constant in the EPO system over the last decade.
