The Patent Controversy

- The patent claimed novelty, despite turmeric being traditionally used in India for the same purpose.
Legal Action and Revocation of the Patent
- In 1996, the Council of Scientific and Industrial Research (CSIR), India, challenged the patent, citing traditional knowledge and lack of novelty.
- CSIR provided evidence from ancient Sanskrit, Urdu, and Hindi texts documenting turmeric’s medicinal use.
- In 1997, the USPTO revoked the patent, recognizing the existence of prior art.
