Pfizer and BioNTech took a swing at Moderna’s Covid-19 patent claims in Massachusetts federal court on Monday, calling them “invalid,” “overbroad” and “unenforceable.”

The defendants also filed counterclaims against the Cambridge, MA-based biotech, seeking a dismissal of the case, recovery of court fees and an official judgment invalidating Moderna’s claims.

Moderna sued Pfizer and BioNTech back in August, alleging that the partners’ Covid-19 vaccine Comirnaty copied parts of Moderna’s vaccine technology patented before the pandemic, when it was developing an mRNA vaccine for MERS, another respiratory illness.

Two Sumitovant Biopharma entities are merging under one name, effective immediately.

Bill Symonds, the current CEO of both Altavant and Enzyvant, is now CEO of the merged company.

After much debate, the US government is now calling for a deadline extension to discuss a controversial potential IP waiver for Covid-19 diagnostics and therapeutics.
