Moderna Inc. sued rival Covid-19 vaccine makers Pfizer Inc. and BioNTech SE, alleging that the companies’ shot infringes on key intellectual property owned by Moderna.
Pfizer and BioNTech’s vaccine relies on messenger RNA technology that Moderna had developed and patented years ago, including a chemical modification that avoids prompting an undesirable immune response, Moderna said in lawsuits filed Friday.
