A patent infringement suit was filed by Bayer Schering against Lupin for violating 3 of their patents. The patents involved in the suit are:
- RE37564 issued on Feb 26, 2002
- RE37838 issued on Sep 10, 2002
- RE38253 issued on Sep 16, 2003
Bayer is a German chemical and pharmaceutical company with core competencies in the fields of health care, nutrition and high-tech materials. Lupin Pharmaceuticals, an India based company, engages in the development and manufacture of branded and generic pharmaceutical products.
Bayer alleged that Lupin submitted to the FDA ANDA No. 20-1661 seeking approval to engage in the commercial manufacture of a generic version of Bayer’s Yaz® tablets, which infringe three of their patents covering the medication.
Bayer is the current holder[iii] of approved New Drug Application (NDA) No. 21-676 for Yaz® tablets (source: Patent Marker), which contain micronized drospirenone and 17α-ethinylestradiol as active ingredients. The United States Food and Drug Administration (FDA) approved Yaz® tablets for the prevention of pregnancy in women, for treatment of moderate acne and symptoms of premenstrual dysphoric disorder in women who elect to use an oral contraceptive. Bayer sells YAZ® tablets in the United States as a 28-day oral contraceptive regimen that contains 24 tablets comprising 3 mg of micronized drospirenone and 0.02 mg of micronized 17α-ethinylestradiol plus 4 placebo tablets.
On October 16, 2013 the parties filed a joint status report in response to the Court’s order. The parties notified the Court that Bayer would not seek further review of the Federal Circuit’s judgment rendered in favor of defendants and advised the Court that the action can be closed, thereby concluding the litigation.
