The Supreme Court allowed Monsanto to claim patents on its genetically modified cotton seeds in the world's biggest producer of the fiber, overturning a decision of a lower court.

"There is a need for the government to look into this whole issue and make an amendment in the law forbidding these companies from charging a patent amount," Ashwani Mahajan, National Co-Convener of Swadeshi Jagaran Manch, told Reuters.

Reuters could not immediately contact India's agricultural ministry.
