GlaxoSmithKline (GSK) has filed a lawsuit against Pfizer and BioNTech in Delaware federal court, alleging infringement of GSK's patents related to messenger RNA (mRNA) technology in their COVID-19 vaccines. GSK claims that Pfizer and BioNTech's Comirnaty vaccines violate its patents developed over a decade ago. Pfizer has expressed confidence in its intellectual property (IP) position and intends to vigorously defend against the claims. GSK is open to licensing its patents on reasonable terms to ensure continued patient access to the vaccines.
