Sanofi sues Pfizer and Moderna over alleged infringement of mRNA delivery patents

Jul 16, 2026·read at Endpoints ↗RegulatoryNegative

Sanofi has filed a lawsuit against Pfizer and Moderna, accusing the two companies of violating its patents covering lipid nanoparticle technology used to deliver mRNA in vaccines.

The French drugmaker's claim adds to a wave of patent disputes, as Arbutus has also launched separate litigation alleging infringement of its own mRNA delivery patents.

These actions highlight the increasing importance of intellectual property rights in the rapidly expanding mRNA vaccine market and could lead to further legal battles that may affect product timelines and licensing arrangements.
