On October 8, 2020, Moderna, the maker of one of the first mRNA-based vaccines for COVID-19 and the recipient of billions of dollars of U.S. government funding, announced that it felt “a special obligation … to use our resources to bring this pandemic to an end as quickly as possible.” As a result, it publicly promised that “while the pandemic continues, Moderna will not enforce our COVID-19 related patents against those making vaccines intended to combat the pandemic.” Moderna broke that promise on August 26, 2022, when it sued Pfizer and BioNTech, the producers of a competing mRNA vaccine, for patent infringement in the U.S. and Germany. This post explains why Moderna’s lawsuits should fail given its irrevocable and continuing nonenforcement pledge.
