COVID-19 vaccine maker Moderna is suing Pfizer and the German drugmaker BioNTech, accusing its main competitors of copying Moderna’s technology in order to make their own vaccine.

Moderna said Friday that Pfizer and BioNTech’s vaccine Comirnaty infringes on patents Moderna filed several years ago protecting the technology behind its preventive shot, Spikevax. The company filed patent infringement lawsuits in both U.S. federal court and a German court.

Pfizer spokeswoman Pam Eisele said the company had not fully reviewed Moderna’s lawsuit, but the drugmaker was surprised by it, given that their vaccine is based on proprietary technology developed by both BioNTech and Pfizer.

She said in an email that Pfizer Inc., based in New York, would “vigorously defend” against any allegations in the case.

BioNTech did not immediately respond to a request from The Associated Press seeking comment.
