FRANKFURT, July 26 (Reuters) - COVID-19 vaccine maker
BioNTech 22UAy.DE said on Tuesday that it and partner Pfizer
PFE.N have filed a complaint with the U.S. District Court in
Massachusetts, seeking a judgment that they did not infringe
U.S. patents held by rival CureVac 5CV.DE .
CureVac earlier this month filed a patent lawsuit in Germany
against BioNTech over its use of mRNA technology and did not
rule out further legal action against BioNTech's partner Pfizer
or rival mRNA vaccine maker Moderna MRNA.O . urn:newsml:reuters.com:*:nL8N2YM300
BioNTech said that CureVac's U.S. patents, which BioNTech
claims in its filing not to be in violation of, were equivalent
to German patents invoked by CureVac in the German court case.
CureVac said in a statement it was aware of BioNTech's legal
action but had not yet been formally served.
"We will review the matter legally in detail and represent
our position accordingly," it added.
