MSF takes Prevnar13 patent battle all the way to Korean Supreme Court

International aid group Médecins Sans Frontières (MSF) has launched legal action in South Korea to try to force a review of Pfizer’s (NYSE: PFE) pneumococcal conjugate vaccine (PCV) patent.

The filing in the country’s Supreme Court comes after a ruling late last year in the Patent Court of Korea which upheld the New York-based pharma giant’s patent for Prevnar13.

The group was encouraged to take action in the country after the same patent was revoked by the European Patent Office (EPO) last year.
