Using Bayh-Dole Act March-In Rights to Lower US Drug Prices.

In December 2023, the Biden-Harris Administration released a proposed framework for exercising government march-in rights (effectively granting compulsory licenses for those patents to generic drug makers) under the Bayh-Dole Act on patents on taxpayer-funded drugs, which has renewed questions about whether march-in rights could promote cost savings through generic competition or harm pharmaceutical innovation. To determine the feasibility of using march-in rights to remove patent barriers to generic competition. This cross-sectional study examined government funding information from multiple sources for patents listed in the Food and Drug Administration (FDA) Orange Book from 1985 to 2023. Data analysis was completed in August 2024. New drug applications (NDAs) with Orange Book-listed patents, including (1) all new molecular entities (NMEs) approved from 1985 to 2022; (2) all NDAs with an Orange Book patent listed between 1985 and 2023; and (3) NDAs with unexpired patents listed in a recent (October 2023) edition of the Orange Book. The main outcome was whether the drugs had any or all patents that were public-sector patents subject to the Bayh-Dole Act, based on combining different data sources for identifying patents that resulted from federal funding. Public-sector patents resulting from intramural research, which are not subject to march-in rights under the Bayh-Dole Act, were identified separately. Of 883 new molecular entities approved from 1985 to 2022, 68 (8%) had a Bayh-Dole patent, but only 18 (2%) had solely Bayh-Dole patents. Of 2832 drugs with patents listed for 1985 to 2023, 142 (5%) had a Bayh-Dole patent, but only 38 (1%) had solely Bayh-Dole patents. Of 1213 drugs with Orange Book patents listed in October 2023, 41 (3%) had a Bayh-Dole patent, but only 14 (1%) had solely Bayh-Dole patents. This cross-sectional study found that, although Bayh-Dole march-in rights could remove patent barriers to generic entry for a few drugs, their overall effect would be limited.
