Genmab Announces that the patents asserted against DARZALEX® in the United States have been declared invalid by summary judgment.

On January 26, 2019 Genmab A/S (Nasdaq Copenhagen: GEN) reported that the U.S. District Court of Delaware has declared the three U.S. patents (Nos. 8,263,746, 9,200,061, and 9,758,590), asserted by MorphoSys AG against Genmab and Genmab’s collaboration partner Janssen Biotech, Inc. (Janssen) are invalid by summary judgment (Press release, Genmab, JAN 26, 2019, View Source [SID1234532904]). The patent infringement lawsuit was initiated by MorphoSys against Genmab and Janssen in April 2016 asserting that activities with DARZALEX (daratumumab) in the United States infringe its U.S. patents, and the case has been pending before the U.S. District Court of Delaware. The summary judgment order declared all three patents invalid due to lack of enablement. As a result of this decision, the jury trial scheduled for February 2019 will not take place. MorphoSys has the opportunity to appeal the district court decision to the U.S. Court of Appeals for the Federal Circuit (CAFC). In addition, during the case a further claim by Janssen and Genmab was included in the case that the three MorphoSys patents were unenforceable due to inequitable conduct by MorphoSys. That issue remains to be decided
