German pharma major Bayer has charged that Indian generic drugmaker Cipla had breached its patent rights by slashing the price of a generic version of its patent-protected cancer drug Nexavar last week. Bayer Pharma has not given its consent to Cipla to launch its generic Sorafenib (sold under the brand name Nexavar) and the companys decision to cut the price of the life-extending kidney and liver cancer drug is a clear patent infringement,a Bayer spokesperson said.
