In brief

Indian scientist Raghunath Mashelkar, former head of the Council of Scientific and Industrial Research, has resigned as the chairman of a government panel on patent laws after charges that some parts of a recent report had been plagiarized. Non-governmental organizations, local pharmaceutical companies and some scientists had alleged that the panel allowed companies to monopolize drugs by letting them patent minor modifications to existing drugs.
