Moderna has filed complaints in the US and Germany claiming that the mRNA technology used to make Pfizer and BioNTech’s Comirnaty vaccine infringes multiple patents that cover its own Spikevax shot.
Among the claims is that Comirnaty was developed using a chemical modification to prevent causing an unwanted immune response in patients which was discovered by Moderna scientists, and that the use of a lipid nanoparticle formulation also infringes its intellectual property.
