04:07 AM EDT, 04/27/2026 (MT Newswires) -- Moderna (MRNA) is facing a patent infringement lawsuit from CureVac, which alleged that Moderna's COVID-19 vaccine Spikevax used its proprietary mRNA technology without authorization, Reuters reported Saturday.

CureVac sued Moderna in Delaware federal court, alleging it copied its mRNA stabilization technology and seeking royalties from Spikevax sales, as part of a broader wave of COVID-19 vaccine IP disputes, according to the report.

Moderna said it is aware of the lawsuit and will defend itself, while continuing to pursue its own patent case, filed in 2022, against Pfizer (PFE) and BioNTech (BNTX), Reuters added.

Moderna didn't immediately respond to a request for comment from MT Newswires.
