Pfizer and its partner BioNTech have asked a U.S. court to revoke Moderna’s patents for COVID-19 vaccine technology.
Pfizer and BioNTech said in new filings to the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board that Moderna’s patents are so broad that they essentially “coopt the entire field” of messenger RNA technology, which is used in some COVID-19 vaccines.
