On March 19, 2018, Novartis and Grifols sued Regeneron in the Southern District of New York, asserting that Regeneron’s manufacture of its EYLEA® and ZALTRAP® products infringes U.S. Patent No. 5,688,688. Previous cases in which Novartis asserted the ’688 patent against MedImmune, Biogen, and Alexion have all been concluded.
