Big pharma´s patent wars in India

India, a country of 1.2 billion people, is a huge potential market for multinational pharma companies. The domestic pharma market in India is expected to grow at 15 to 20 per cent annually to be a US $49 billion to $74 billion market by 2020[1]. India is a big hope for the future, at a time when margins of the pharmaceutical industry decline. But in India this huge potential is now seriously undermined by intellectual property issues.
