Sept 18 (Reuters) - Moderna ( MRNA ) has settled related

lawsuits that accused it of misusing Alnylam Pharmaceuticals' ( ALNY )

patented technology in its COVID-19 vaccines, according

to filings on Thursday in Delaware federal court.

The companies told the court that they had resolved their

dispute and asked to dismiss Alnylam's claims with prejudice,

which means they cannot be refiled. A spokesperson for Alnylam

confirmed the settlement but declined to comment or provide

further details.

Spokespeople for Moderna ( MRNA ) did not immediately respond to a

request for comment and more information on the agreement.

The cases were part of a web of patent lawsuits brought by

biotech companies against COVID-19 vaccine makers Moderna ( MRNA ),

Pfizer ( PFE ) and BioNTech over technology in their

shots. Moderna ( MRNA ) has sued Pfizer ( PFE ) and BioNTech for patent

infringement in a separate ongoing case.

Cambridge, Massachusetts-based Alnylam first sued Moderna ( MRNA )

for patent infringement in 2022, alleging its vaccines used

Alnylam's lipid nanoparticle (LNP) technology to deliver genetic

material into the body.

Alnylam requested a share of royalties from Moderna's ( MRNA )

COVID-19 vaccine Spikevax. Moderna ( MRNA ) said in a company report that

it earned $3.1 billion in revenue last year, most of which was

from Spikevax sales.

Moderna ( MRNA ) denied Alnylam's infringement allegations and argued

that the patents were invalid.

A U.S. appeals court upheld a ruling for Moderna ( MRNA ) by Delaware

U.S. District Judge Colm Connolly in June. Connolly also ruled

against Alnylam in another case against Moderna ( MRNA ) last year.

Alnylam has also filed separate ongoing patent lawsuits over

Pfizer ( PFE ) and BioNTech's COVID-19 shots. Connolly ruled against

Alnylam in that dispute earlier this year.

The cases are Alnylam Pharmaceuticals Inc ( ALNY ) v. Moderna Inc ( MRNA ),

U.S. District Court for the District of Delaware, Nos.

1:22-cv-00335 and 1:23-cv-00580.
