Rituxan® Patents Resurface at the PTAB

March 10, 2017

Two patents related to methods of treating rheumatoid arthritis (RA) patients with rituximab have been brought before the PTAB for a third time – with mixed results.

The challenged patents are U.S. Patent Nos. 7,976,838 and 7,820,161.  The ’838 patent, owned by Genentech, Inc., relates specifically to methods of treating RA patients who demonstrate an inadequate response to a TNFa-inhibitor.  The ’161 patent, co-owned by Genentech and Biogen, Inc., is directed to methods of treating RA patients with both rituximab and methotrexate.  Rituximab is a chimeric murine / human monoclonal antibody which, in addition to treating RA, was also the first FDA-approved monoclonal antibody cancer treatment, targeting cancers of the white blood system.  Currently marketed as Rituxan®, it brought in over $7 billion in global sales in 2015.
