The Controller General of Patents has issued guidelines for processing of patent applications relating to Traditional Knowledge (TK) and biological materials on November 08, 2012.

The guidelines have been issued in lieu of the fact that a number of the Indian Patent Applications relating to herbal (plant) compositions/extracts/alkaloids and other biological resources from India are being granted in India even though their corresponding Foreign applications in the jurisdictions (US/EP/JPO etc.) having an access to the Traditional Knowledge Digital Library (TKDL) are rejecting the corresponding applications. Different Examiners & Controllers have been analyzing the patentability criteria of inventions differently due to the lack of any standard procedures.
