| Abstract: | The recent patent increase is decomposed into compnents representing: 1) an increase in resources made available to research and development, 2) an across-the-board rise in the patent yield of an R&D dollar and 3) changes in the patent yield in individual industries. Two high tech fields, computer hardware and pharmaceuticals, account for 22 percent of the patent increase. While these two industries had the fastest R&D growth among the industries that were studied, the pharmaceutical industry experienced a decline in its patent yield, limiting its patent growth. It is shown that increased R&D spending accounts for 70 percent of the patent increase. |
