A patent appeals board dismissed on Monday Bayer AG's
Last year, the patents office, under a mechanism called "compulsory licence", allowed Natco Pharma
Bayer challenged this decision with the Intellectual Property Appellate Board (IPAB) in Chennai.
Although dismissing the petition, the board did order Natco Pharma to pay a royalty of 7% on sales of generic Nexavar to Bayer, an increase from the 6 percent royalty that had earlier been set.
