World Patent Information, 1982, vol. 4, issue 2, 56-59

Abstract: Graphical representation of the number of patent families in the year of first filing, or of the cumulative number of patent families since a certain year, gives useful information regarding the inventions made in a field of coherent subjects. This provides R & D units with a better base for their policy than corresponding surveys of journal articles.
