Meaning. TK is knowledge, know-how, skills and practices developed, sustained and passed from generation to generation within a community, often forming part of its cultural or spiritual identity. It includes agricultural, medicinal (Ayurveda, Siddha, Unani, Yoga), ecological knowledge, and traditional cultural expressions (folklore). It is typically collective, oral, cumulative and not novel in the patent-law sense (it is already in the public domain, so the patent system tends to fail to protect it and invites misappropriation).
Biopiracy and landmark cases (very high yield)
-
Turmeric (haldi) patent: US Patent No. 5,401,504 (1995) was granted to the University of Mississippi Medical Center for use of turmeric in wound healing. India's CSIR challenged it with ancient Sanskrit texts and a 1953 JAMA paper; the USPTO revoked the patent in 1997 – the first successful challenge by a developing country to a biopiracy patent.
-
Neem patent: European Patent No. 436,257 (granted 1994) to the US Department of Agriculture and W.R. Grace & Co. for a fungicidal neem-oil method; opposed in Europe by Indian and international organisations (including Vandana Shiva, the Research Foundation for Science, Technology and Ecology and the European Greens); revoked by the EPO in 2000 and the revocation was upheld on appeal in 2005 for lack of inventive step (no novelty because of prior use of neem in India).
-
Basmati rice: RiceTec Inc. obtained US Patent No. 5,663,484 (1997) claiming Basmati lines and grains; after India's challenge (via APEDA/Government) the USPTO narrowed the claims (2001), and RiceTec withdrew the Basmati-named claims; this led to Basmati's GI registration in India (2016).
-
Others: Hoodia (San people, South Africa) and Kava, Ayahuasca, Hoodia are international examples of benefit-sharing disputes.
India's legal measures to protect TK
-
Traditional Knowledge Digital Library (TKDL): established in 2001 by CSIR and the Department of AYUSH, a searchable database of Indian systems of medicine (Ayurveda, Unani, Siddha, Yoga, Sowa-Rigpa). Information is classified using the Traditional Knowledge Resource Classification (TKRC), modelled on the International Patent Classification, and made available in English, French, German, Japanese and Spanish. Access agreements allow patent examiners at the EPO, USPTO, JPO, UKIPO and other offices to search TKDL as prior art, preventing erroneous patents.
-
Patents Act (2002 Amendment): Section 3(p) (TK is not an invention); Section 10(4)(d)(ii)(A) (disclosure of the source and geographical origin of biological material); Section 25(1)(j)–(k) and 25(2)(j)–(k) (pre-grant and post-grant opposition on non-disclosure and on anticipation by TK); Section 64(1)(p)–(q) (revocation).
-
Biological Diversity Act 2002: PIC/MAT, benefit sharing (Sections 3, 6, 21), BMCs and People's Biodiversity Registers (to document local knowledge and prevent misappropriation), Section 36(5).
-
GI Act 1999: protects collective indigenous products linked to place (handlooms, handicrafts).
-
Copyright: folklore as traditional cultural expressions is only indirectly protected (works whose authors are unknown; the Copyright Act has no sui generis TCE right, although Sections 22–23 deal with anonymous works).
-
PPVFR Act 2001: farmers' varieties and farmers' rights.
International developments
-
CBD Article 8(j) (respect and maintain TK, innovations and practices of indigenous and local communities and promote their wider application with their approval and involvement, with equitable benefit sharing) and Nagoya Protocol 2010 (access to genetic resources and associated TK, benefit sharing, compliance measures).
-
WIPO IGC (Intergovernmental Committee on IP and Genetic Resources, Traditional Knowledge and Folklore, established 2000): led to the WIPO Treaty on Intellectual Property, Genetic Resources and Associated Traditional Knowledge, adopted 24 May 2024, the first WIPO treaty directly addressing TK. It requires patent applicants to disclose the country of origin or source of genetic resources, and the Indigenous Peoples or local community providing associated TK. Enters into force after ratification by 15 contracting parties (verify current status).
-
TRIPS Council debate on a mandatory disclosure of origin (proposed amendment to TRIPS Art. 29bis, supported by India, Brazil and others).
-
ITPGRFA 2001: a multilateral system for access and benefit sharing for plant genetic resources for food and agriculture, and farmers' rights.
Analysis points (for conceptual MCQs). (i) TK is not patentable because it lacks novelty (public domain) and an identifiable inventor. (ii) The defensive approach (databases like TKDL preventing wrongful patents) is distinct from positive protection (granting rights to communities). (iii) Disclosure of origin is a linking mechanism between patent law and the CBD. (iv) The 2023 amendment's exemption for codified TK is criticised for weakening community benefit sharing.
