Novartis AG is not going quietly into the night after the U.S. Court of Appeals for the Federal Circuit reversed itself, invalidating a method patent covering a dosing regimen for the company’s blockbuster multiple sclerosis drug, Gilenya (fingolimod). After the split opinion came down June 21 from the three-judge panel, Novartis said it planned to file a petition seeking further review of the decision by the full court.
