The purpose of this paper is to provide insights into the use of patents as a generally accepted indicator of
new knowledge and intermediate outputs of innovative activity more generally. It is intended as a background paper for further analysis based on the new so-called FEPOCI database on Finnish patents and related citations granted at the European Patent Office from the years 1991-2004.
