Bronwyn H. Hall & Rose Marie Ham: The Patent Paradox Revisited

Research work done at Univ. of California, Berkely, published 1999 by National Bureau of Economic Research Inc. Finds that the surge in patents in the semiconductor industry in the 1980-90s does not reflect a surge in R&D activity.

Kortum & L 1998: Since the late 1980s, the number of patents granted to US companies by the USPTO has sharply risen. Many people believe that this is due to a more patent-friendly policy created by political changes in the early 80s such as the Bayh-Dole act and the institution of the Court of Appeal for the Federal Circuit (CAFC). This study collects statistical data to suggest that a surge in patentable innovation and an improvement in patent-oriented innovation managment may be more important causes. It also shows that software and biotech, while considered to be the most important areas of innovation, still amount for a total of only about 5% of the US patents. While patent-oriented innovation was on the rise, R&D investments on the whole dropped. This is one of a series of studies by Samuel Kortum and Josh Lerner from the Department of Economics of Boston University.
