California: Biotech firm Promosome LLC sued Moderna, Pfizer and BioNTech, in federal court in San Diego, California, on Tuesday, accusing their COVID-19 vaccines of infringing a patent related to messenger RNA technology.
The lawsuits add to a web of patent disputes between biotech companies over technology used in the coronavirus shots, including a case brought last year in Massachusetts by Moderna against Pfizer and its partner BioNTech.
Promosome accused the companies of copying technology that allows for doses of mRNA that are small enough to use safely and effectively in the vaccines.
Promosome asked the court for a share of royalties from the shots. Pfizer earned $37.8 billion from sales of its COVID-19 vaccine Comirnaty last year, while Moderna made $18.4 billion from its vaccine Spikevax.
Representatives of Moderna, Pfizer and BioNTech did not immediately respond to requests for comment on the lawsuit.
