In February 2018 a jury declared Biogen’s patent invalid vis-à-vis Merck KGaA, Darmstadt, Germany. The jury verdict was overturned by the District Court Judge, who upheld the validity of Biogen’s patent.

On 28 September 2020 the U.S. Court of Appeals for the Federal Circuit set aside the decision of the District Court Judge, invalidated Biogen’s patent and instructed the District Court to reinstate the jury verdict.
