(Reuters) - Moderna Inc failed to persuade a Delaware federal judge on Wednesday to shift liability to the U.S. government for patent infringement allegations based on COVID-19 vaccines it provided for the government's vaccination effort.
Chief Judge Colm Connolly's ruling for Alnylam Pharmaceuticals Inc came just over a month after a different judge in Delaware rejected Moderna's similar motion in another vaccine patent lawsuit.
Connolly did not include the reasoning for his decision in his order, which he announced from the bench following arguments in the case. Representatives for Moderna and Alnylam did not immediately respond to requests for comment.
Cambridge, Massachusetts-based Alnylam sued both Moderna and Pfizer Inc in Delaware last year, seeking royalties for the lipid nanoparticle (LNP) technology their vaccines use to deliver genetic material known as mRNA.
The cases are part of a wave of patent lawsuits that have been filed over technology used in the COVID-19 shots, including one filed by Moderna against Pfizer last year.
Moderna said in the Alnylam case that the court should dismiss claims that were based on vaccines it sold to the U.S. government and that Alnylam should instead seek damages from the government itself. It cited a law that was previously used to keep patent disputes from interfering with the supply of war materials during World War One.
Moderna made the same argument in a motion to dismiss part of another patent lawsuit brought by Arbutus Biopharma Corp and Genevant Sciences GmbH.
U.S. District Judge Mitchell Goldberg rejected Moderna's motion in that case last year and said it had not yet proven the government was more than an "incidental beneficiary" of the shots.
Goldberg denied the motion for a second time last month after the federal government backed Moderna's position.
