Prandin, known chemically as repaglinide, and its combination with the commonly prescribed type 2 diabetes drug metformin, sold as PrandiMet, had sales of about $200 million in 2012 for Novo.
Sun Pharma said it would be eligible for a 180-day marketing exclusivity in the United States for the drug.
A US appeals court last month found the patent on Novo's Prandin diabetes drug in combination with metformin to be invalid, paving the way for the introduction of a generic version of the drug.
