GlaxoSmithKline Sues BioNTech, Pfizer Over COVID-19 Vaccine Technology

GlaxoSmithKline sued Pfizer and BioNTech 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.

A Pfizer spokesperson said in a statement that the company is “confident in our IP position around Comirnaty” and intends to “vigorously defend” against GSK’s claims. A BioNTech spokesperson declined to comment on the complaint.
