| Abstract |
While there has been much discussion by policymakers and stakeholders about the effects of "secondary patents" on the pharmaceutical industry, there is no empirical evidence on their prevalence or determinants. Characterizing the landscape of secondary patents is important in light of recent court decisions in the U.S. that may make them more difficult to obtain, and for developing countries considering restrictions on secondary patents. |
