Item 8.01 Other Events.
On May 11, 2020, Exelixis, Inc. (Exelixis) filed a complaint for patent infringement against MSN Pharmaceuticals, Inc. (MSN) asserting U.S. Patent Nos. 7,579,473 and 8,497,284 in the United States District Court for the District of Delaware (the 473/284 Complaint), arising from MSN’s amendment of its Abbreviated New Drug Application (ANDA), originally filed with the U.S. Food and Drug Administration (FDA) in September 2019 for a generic version of CABOMETYX® (cabozantinib) tablets (20 mg / 40 mg / 60 mg). MSN’s ANDA now requests approval to market a generic version of CABOMETYX tablets prior to expiration of U.S. Patent No. 7,579,473 and U.S. Patent No. 8,497,284. In the 473/284 Complaint, Exelixis is seeking, among other relief, equitable relief enjoining MSN from infringing these patents.
The 473/284 Complaint is in addition to Exelixis’ original complaint for patent infringement arising from MSN’s ANDA filed on October 29, 2019 (the Original Complaint), asserting U.S. Patent No. 8,877,776 (the ‘776 Patent), which expires later than the patents asserted in the 473/284 Complaint. In the Original Complaint, Exelixis is seeking, among other relief, equitable relief enjoining MSN from infringing the ‘776 Patent as well as an order that the effective date of any FDA approval of MSN’s ANDA would be a date no earlier than the expiration of the ‘776 Patent on October 8, 2030.
