India's successful challenging of a U.S. patent (No. 5,401,504) on the use of turmeric (Curcuma longa L., Zingiberaceae) for healing has been an encouraging victory for Indian activists campaigning to protect indigenous wisdom.
After a complex legal battle, the U.S. Patents and Trademarks Office ruled on Aug. 14 that a patent for turmeric issued to the University of Mississippi Medical Center in December 1993 was invalid because it was not a novel invention.
The patent was contested by India's Council for Scientific and Industrial Research (CSIR), which combined scientific evidence with legal savvy to take on the biopirates. Says an excited R. A. Mashelkar, director-general of the CSIR, "This success will enhance the confidence of the people and help remove fears about India's helplessness on preventing bio-piracy and appropriation of inventions based on traditional knowledge."
The turmeric patent was just one of the hundreds that the North has claimed by ignoring indigenous and existing knowledge. Vandana Shiva, a global campaigner for a fair and honest Intellectual Property Rights system, says patents on Neem, Amla, Jar Amla, Anar, Salai, Dudhi, Gulmendhi, Bagbherenda, Karela, Erand, Rangoon-kibel, Vilayetishisham and Chamkura need to be revoked.
This can be done if laws are changed to ensure protection against bio-piracy, activists say, because "chasing every patent based on traditional knowledge will involve huge expenses and efforts," according to farm scientist Devinder Sharma.
Under World Trade Organisation (WTO) rules, patents are provided for inventions that qualify for their novelty, non-obviousness, and utility. The turmeric patent failed to satisfy the criteria of novelty as turmeric paste has been used to treat wounds and stomach infections for centuries by Indians.
It is the WTO which has to protect indigenous knowledge, argues Sharma, who says, "governments of developing countries cannot chase and challenge every indigenous knowledge-based product patent. Patent laws need to be changed, the onus of proof reversed and companies should give an undertaking that the patent they are seeking is not based on traditional wisdom."
Suman Sahai of the New Delhi-based Gene Campaign would like the government to use the turmeric case to "press the North to reform its own laws governing intellectual property rights, instead of pressuring the South to change its laws."
Vandana Shiva points out that "examples of bio-piracy make it clear that it is not just Indian patent laws that need to be changed. The American laws also need to be changed to fit into a fair and honest global Intellectual Property Rights system."
