Narrative Opinion Summary
In this patent infringement case, Bayer Pharma AG and its affiliates (collectively 'Bayer') alleged that Watson Laboratories, Inc. ('Watson') infringed U.S. Patent No. 8,071,577, which covers a multi-phasic oral contraceptive regimen involving estradiol valerate and dienogest, ingredients in Bayer’s Natazia® product. Following a bench trial, the court concluded that Watson’s proposed products infringed the asserted claims of the '577 patent. Watson contended the claims were invalid due to obviousness and obviousness-type double patenting. However, the court found Watson failed to present clear and convincing evidence to support these invalidity arguments. Bayer succeeded in proving secondary considerations of non-obviousness, such as addressing a long-felt need and prior failed attempts by others to develop a similar product. The court emphasized that the burden of proof rested with Watson to establish patent invalidity, a standard it did not meet. As a result, the court ruled in favor of Bayer, confirming the validity of the patent claims and Watson’s infringement, thereby upholding Bayer’s patent rights against Watson’s ANDA submission for a generic version of Natazia®.
