German pharmaceutical and chemicals company Bayer AG (BAYN.XE) said Tuesday it has dropped its patent suit in Delaware against Teva Pharmaceutical Industries Ltd. (TEVA) and Barr Pharmaceuticals Inc. (BRL) for infringing on its oral contraceptive Yaz.

Bayer had filed the suit claiming that Teva's generic contraceptive Gianvi infringed on Yaz.

However, Bayer said Tuesday it is maintaining its patent suit against Teva and Barr in Nevada.
