Final settlement of Genmab-MorphoSys patent dispute on Darzalex

1 February 2019

Danish biotech Genmab (OMX: GEN) revealed on Thursday that the patent infringement lawsuit launched by Germany-based MorphoSys (FSE: MOR) relating to Darzalex (daratumumab) is finally over.

Multiple myeloma treatment Darzalex generated sales of $2.03 billion in 2918 for Genmab’s partner, Johnson & Johnson (NYSE: JNJ) subsidiary Janssen.

As previously reported, on January 25, the US District Court of the District of Delaware ruled that all three patents that MorphoSys had asserted against Genmab and Janssen Biotech, 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 US Court of Appeals for the Federal Circuit.
