Patent reform: a mixed blessing for the U.S. economy?

The 1980s represented a period of dramatic change in the design and enforcement of U.S. intellectual property law. Many of these changes were adopted in the hopes of stimulating private research and development and improving the technological competitiveness of American industries. This article examines the effects of an especially important aspect of these changes: many more inventions qualify for patent protection than before. While it seems logical that making patents easier to obtain will encourage more inventive activity, economic analysis reveals this is not always true, and it is less likely to be true in industries that innovate rapidly.
