New Delhi. Healthcare campaigners have welcomed India’s rejection of a legal bid by Swiss company Novartis to patent a new version of its cancer drug, Glivec."The ruling will save a lot of lives across the developing world,” said aid agency Medecins Sans Frontieres (MSF).The decision means generic drugmakers can continue to sell cheaper copies of Glivec in India, one of the fastest growing pharmaceutical markets.Novartis said the Supreme Court’s ruling "discourages future innovation”.Indian authorities denied the firm’s plea on the grounds that the updated version was only slightly different from the previous one."This ruling is a setback for patients that will hinder medical progress for diseases without effective treatment options,” said Ranjit Shahani, vice-chairman and managing director of Novartis India.Glivec, which is used to treat chronic myeloid leukaemia and other cancers, costs about $2,600 a month.The generic equivalent is currently available in India for just $175.‘Big relief’There were concerns that, if granted, a patent could threaten access to cheap generic versions of life-saving drugs in poorer countries."The ruling has come as a big relief,” said MSF lawyer Leena Menghaney. "The ruling doesn’t mean no patents will be granted in India, but the abusive practice of seeking many patents for one drug will be curbed.”Anand Grover, a lawyer representing Cancer Patients Aid Association, said he was "ecstatic with the ruling”."This will go a long way in providing affordable medicine for the poor,” he said.Novartis applied for a patent in 2006 for its new version of the drug, arguing that it was easier to absorb and therefore qualified as an innovation.However, the Indian patent authority rejected the application based on a law aimed at preventing companies from getting fresh patents by making only minor changes to existing drugs, a practice known as "evergreening”.Officials also turned down a subsequent appeal by the company three years later.The AFP news agency quoted the court as saying that the updated drug "did not satisfy the test of novelty or inventiveness” as required by the law.The previous version of Glivec did not have a patent, as it preceded India’s 2005 patent law.Setting a precedent?Patents usually protect the companies for 20 years of exclusive sales. After that, it is open to other firms who can make cheaper copies of the original drug.Once the protection expires, the first company to challenge the patent gets an exclusive right to sell the copy for 180 days.After 180 days, more companies can sell the generic versions, potentially resulting in a further price drop.India’s generic drug makers are among the biggest in the world and many expect them to benefit from patents expiring in the coming years.
