The Controller General of Patents, Designs and Trademark on 9 May 2016 granted the patent to Gilead Sciences for its Hepatitis C drug Sofosbuvir (brand name Sovaldi) in India.
The drug, which has a list price of 1000 US dollar a pill in the United States, was rejected for a patent by the Indian patent authority in January 2015. It was rejected on the basis that it represented only minor changes to a previous formulation, and the company already had licensing deals with manufacturers in India.

• The virus persists in the liver in about 75% to 85% of those initially infected.

• There is no vaccine against hepatitis C.
• Chronic infection can be cured about 90% of the time with treatments that include the medications sofosbuvir or simeprevir.
• An estimated 130–200 million people worldwide are infected with hepatitis C.
• It occurs most commonly in Africa and Central and East Asia.
• The existence of hepatitis C, originally identifiable only as a type of non-A non-B hepatitis, was suggested in the 1970s and proven in 1989.
• Hepatitis C infects only humans and chimpanzees.
