Legal Risks

To find out more about the Bayer Group’s legal risks, please see Note 32 to the consolidated financial statements in the Bayer Annual Report 2015, which can be downloaded free of charge at Since the Bayer Annual Report 2015, the following significant changes have occurred in respect of the legal risks:


Yasmin™ / YAZ™: As of July 14, 2016, the number of claimants in the pending lawsuits and claims in the United States totaled about 500 (excluding claims already settled). Claimants allege that users have suffered personal injuries, some of them fatal, from the use of Bayer’s drospirenone-containing oral contraceptive products such as Yasmin™ and / or YAZ™ or from the use of Ocella™ and / or Gianvi™, generic versions of Yasmin™ and YAZ™, respectively, marketed by Barr Laboratories, Inc. in the United States.

As of July 14, 2016, Bayer had reached agreements, without admission of liability, to settle approximately 10,500 claims in the United States for venous clot injuries (primarily deep vein thrombosis or pulmonary embolism) for a total amount of about U.S. $2.08 billion. Bayer will continue to consider the option of settling such claims after a case-specific analysis of medical records. At present, about 100 such claims are under review.

In August 2015, Bayer reached an agreement to settle, without admission of liability, lawsuits and claims in which plaintiffs allege an arterial thromboembolic injury (primarily strokes and heart attacks) for a total maximum aggregate amount of U.S. $56.9 million. The participation thresholds have been met (97.5% of those who are eligible, and 96% of those who are eligible and allege death or catastrophic injuries) and the settlement was funded in May 2016. As of July 14, 2016, about 10 of the 500 above-mentioned claimants alleged arterial thromboembolic injuries.

Xarelto™: As of July 14, 2016, U.S. lawsuits from approximately 11,500 recipients of Xarelto™, an oral anticoagulant for the treatment and prevention of blood clots, had been served upon Bayer. Plaintiffs allege that users have suffered personal injuries from the use of Xarelto™, including cerebral, gastrointestinal or other bleeding and death, and seek compensatory and punitive damages. Additional lawsuits are anticipated. As of July 14, 2016, ten Canadian lawsuits relating to Xarelto™ seeking class action certification had been served upon Bayer.

Betaferon™ / Betaseron™: Since 2010, Bayer and Biogen Idec have been litigating in U.S. federal court about the validity of a Biogen patent and its alleged infringement by the production and distribution of Betaseron™, Bayer’s drug product for the treatment of multiple sclerosis. In March 2016, the U.S. federal court decided a disputed issue regarding the scope of the patent in Biogen’s favor. Bayer disagrees with the decision, which may be appealed at the conclusion of the proceedings in the U.S. federal court. This development does not change Bayer’s belief that it has meritorious defenses in this dispute and that it will continue to defend itself vigorously.

Beyaz™ / Safyral™: In the patent infringement proceedings against Watson Laboratories, Inc., the U.S. Court of Appeals for the Federal Circuit in May 2016 invalidated the patent claims asserted by Bayer and reversed last year’s judgment by a U.S. federal court. Bayer filed a petition for rehearing. Beyaz™ and Safyral™ are Bayer’s oral contraceptives containing folate. In September 2015, a U.S. federal court ruled in favor of Bayer regarding both the validity of the patent and the infringement thereof by Watson. Watson had filed Abbreviated New Drug Applications with a Paragraph IV certification (“ANDA IV”) seeking approval of generic versions of both Beyaz™ and Safyral™ in the United States and appealed the decision.

Finacea™: In May 2016, the U.S. Court of Appeals for the Federal Circuit affirmed last year’s decision by a U.S. federal court that Bayer’s patent relating to Finacea™ topical gel is valid and infringed by Glenmark Generics Ltd. Glenmark had filed an ANDA IV seeking approval of a generic version of Finacea™ in the United States and appealed the U.S. federal court decision.
