Appeals Court Upholds Ruling For Moderna In COVID-19 Vaccine Patent Case

June 05, 2025

Reuters (6/4, Brittain) reports that Moderna successfully convinced a US appeals court Wednesday to uphold a Delaware federal court ruling that “undercut patent infringement claims by biotech company Alnylam Pharmaceuticals over Moderna’s blockbuster COVID-19 vaccine Spikevax.” Alnylam, which lost a similar dispute in a related Moderna case last year, “has filed separate, ongoing patent lawsuits over Pfizer’s COVID shots.” Alnylam sued both companies “for patent infringement in 2022 for allegedly using its lipid nanoparticle (LNP) technology in their vaccines to deliver genetic material into the body.”
