If Sanofi receives BMS’s Patent Assumption Notice, Sanofi shall assign to BMS the title to such patent on or before the Abandonment Date and BMS shall cover all of the costs and expenses of such assignment. If BMS fails to provide a Patent Assumption Notice, Sanofi shall be free to abandon such patent, in its sole and absolute discretion, on the Abandonment Date or thereafter. If Sanofi assigns to BMS the title to such patent, BMS shall pay all further costs relating to the patent, including, but not limited to, all costs and expenses relating to prosecution costs, maintenance costs and litigation costs, and Sanofi shall be relieved of all of its rights and obligations with respect to such patent after such date. The procedures set forth herein shall apply each time Sanofi intends to abandon a patent prior to the Expiration Date.”
