New Delhi, Feb 23: The Supreme Court today directed the Centre to file its objections to the US multinational Monsanto's bid to claim a patent on an Indian variety of wheat pending before the European patent office. The direction was issued by a bench of Chief Justice V N Khare and Justice S H Kapadia when the Centre stated that the patent sought was not for an Indian variety. The court, however, said that it did not want to take any risk and asked the Centre to file the objections even then. The court also asked the Centre to respond to the Public Interest Litigation (PIL) filed by the Centre for science, technology and ecology and green activist Vandana Shiva alleging that Centre was not contesting the patent claim of the US multinational. The court directed listing of the PIL on March 12 for further hearing. Bureau Report
