There are 2 aspects to this knowledge. One is related to the traditional knowledge that is being continuously documented by CSIR and has been shared with leading patent offices of the world. This enables them to disallow the grant of the patents if they are based on India's traditional knowledge. Many NGOs have been involved in transfer of this knowledge to foreign nations. The other aspect is related to jugaad inventions that are examined only for novelty. India may allow the grant of rights for this kind of inventions, in future. ( Arun Kashyap )
