Moderna to Pay Up to $2.25B to Settle COVID Vaccine Patent Dispute

The deal ends years of legal challenges over the technology that made Moderna's COVID-19 vaccine possible.

Published on Mar. 4, 2026

Moderna has agreed to pay up to $2.25 billion to settle a long-running legal dispute with Genevant Sciences and Arbutus Biopharma over the lipid nanoparticle technology used in Moderna's COVID-19 vaccine. The deal resolves all U.S. and international legal actions accusing Moderna of using the technology without permission.

Why it matters

The settlement removes the risk of potentially high royalty payments for Moderna on its COVID-19 and future COVID/flu combination vaccines, allowing the company to avoid a costly legal battle. It also highlights the ongoing patent disputes in the lucrative COVID-19 vaccine market, with multiple companies seeking a share of the tens of billions in sales.

The details

Under the deal, Moderna will pay $950 million upfront in July 2026, with an additional $1.3 billion that depends on the outcome of a separate legal appeal. Moderna said it would not owe Genevant and Arbutus any royalties for the lipid nanoparticle technology in its future vaccines. The lipid nanoparticles act as a protective shell that helps the mRNA in Moderna's vaccine reach human cells intact.
