Copenhagen, Denmark; January 31, 2019 - Genmab A/S (Nasdaq Copenhagen: GEN) announced today that the patent infringement lawsuit launched by MorphoSys relating to DARZALEX® is finally over.

As previously reported, on January 25, 2019, the U.S. District Court of the District of Delaware ruled that all three patents that MorphoSys had asserted against Genmab and Janssen Biotech, Inc. (Janssen) are invalid.  As noted at that time, Genmab and Janssen's allegations that the patents were unenforceable for inequitable conduct remained to be resolved, and MorphoSys had the right to appeal the invalidity decision to the United States Court of Appeals for the Federal Circuit.

Today, MorphoSys dismissed its infringement claims with prejudice (for good), and Genmab and Janssen have, in turn, dismissed their inequitable conduct claims.  As such, there will be no further proceedings in the case. The case is now over. 

"Genmab is an antibody innovation powerhouse committed to conducting business in an ethical manner in accordance with our core values, and we are very pleased that this case is finally over and behind us," said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.
