April 25 (Reuters) - GlaxoSmithKline GLAX.NS sued
Pfizer PFE.N and BioNTech 22UAy.DE in Delaware federal court
on Thursday, accusing them of infringing GSK patents related to
messenger RNA (mRNA) technology in the companies' blockbuster
COVID-19 vaccines.
GSK said in the lawsuit that Pfizer and BioNTech's Comirnaty
vaccines violate the company's patent rights in mRNA-vaccine
innovations developed "more than a decade before" the outbreak
of the COVID-19 pandemic.
