Protection of Traditional Knowledge in Patents

Protection of Traditional Knowledge in Patents refers to the legal mechanisms used to prevent the unauthorized patenting, commercial exploitation, or misappropriation of knowledge developed and preserved by indigenous communities and local populations over generations.

Traditional knowledge includes knowledge relating to medicinal plants, agricultural practices, herbal formulations, biodiversity, traditional healing methods, and natural resources.

For example, turmeric has traditionally been used in India for wound healing. If a person attempts to obtain a patent claiming this traditional use as a new invention, the patent may be challenged because the knowledge already exists in the public domain.

The protection of traditional knowledge is particularly important in India because indigenous communities and local populations have contributed significantly to traditional medicine, agriculture, and biodiversity conservation.

Central principle: Patent law must protect genuine innovation without allowing individuals or corporations to obtain exclusive rights over knowledge that already belongs to traditional communities.

1. Legal framework in India

A. Patents Act, 1970

Section 3(p) expressly excludes from patentability an invention which, in effect, is traditional knowledge or which is an aggregation or duplication of known properties of traditionally known components.

Section 3(j) excludes plants and animals in whole or any part thereof, other than microorganisms, and essentially biological processes for production or propagation of plants and animals.

Sections 25 and 64 provide mechanisms for opposing or revoking patents, including on grounds such as lack of novelty and prior publication.

B. Biological Diversity Act, 2002

The Biological Diversity Act regulates access to biological resources and associated knowledge. It seeks to ensure conservation, sustainable use, and fair and equitable sharing of benefits arising from the use of biological resources.

This is particularly relevant where commercial inventions are based on medicinal plants or biological resources traditionally used by local communities.

C. Traditional Knowledge Digital Library (TKDL)

The TKDL was established by CSIR and the Ministry of AYUSH to document traditional medicinal knowledge in a format accessible to patent examiners.

It translates and classifies traditional knowledge from ancient texts into patent-searchable formats, helping examiners identify existing knowledge and prevent the grant of patents that lack novelty or inventive step.

2. Important case laws

A. Turmeric Patent Case — University of Mississippi Medical Center (1997)

The United States Patent and Trademark Office granted US Patent No. 5,401,504 in 1995 for the use of turmeric in wound healing.

India's Council of Scientific and Industrial Research (CSIR) challenged the patent by submitting evidence from ancient Sanskrit texts and a 1953 publication documenting the traditional use of turmeric for wound healing.

The USPTO revoked the patent in 1997 because the claimed use was already known and therefore lacked novelty.

Legal significance: The case demonstrates that traditional knowledge can constitute prior art and prevent the grant of an invalid patent. It is a landmark example of defensive protection against biopiracy.

B. Neem Patent Case — W.R. Grace and USDA (2000)

A European patent was granted in 1994 for the fungicidal properties of neem oil.

Indian farmers and environmental organizations challenged the patent before the European Patent Office (EPO), arguing that the fungicidal use of neem was already known in traditional Indian practices.

The EPO revoked the patent in 2000 after considering evidence of prior knowledge and use.

Legal significance: The decision illustrates how traditional agricultural and medicinal knowledge can defeat patent claims that lack novelty or inventive step.

C. Basmati Rice Patent Dispute — RiceTec Inc. (1997–2001)

RiceTec, a US company, obtained a patent relating to certain rice varieties and characteristics associated with Basmati rice.

India challenged the patent because Basmati was traditionally cultivated in the Indian subcontinent and had established agricultural and commercial significance.

Following objections and re-examination, several claims were withdrawn or narrowed.

Legal significance: The dispute highlights the importance of protecting traditional agricultural knowledge and geographical identity against overly broad patent claims. It also demonstrates that patent protection must be distinguished from geographical indication protection.

D. Pangaea Laboratories Patent Application (2015)

A UK-based company sought a European patent for a composition involving turmeric, pine bark, and green tea for treating hair loss.

CSIR's Traditional Knowledge Digital Library submitted evidence demonstrating that these ingredients had already been used in traditional Indian medicine for similar purposes.

Following the submission of prior-art evidence, the application was deemed withdrawn in June 2015.

Legal significance: The case illustrates the practical effectiveness of the TKDL in preventing patents based on previously documented traditional knowledge.

3. International legal framework

The international framework seeks to balance patent incentives with the rights and interests of indigenous peoples and local communities.

4. Illustrative example

Suppose a pharmaceutical company discovers that a plant traditionally used by an Indian tribal community has medicinal properties.

The company applies for a patent claiming the plant's known medicinal use as a new invention.

The patent examiner may reject the application if the claimed invention is already documented in traditional knowledge and does not satisfy the requirements of novelty and inventive step.

However, if the company develops a genuinely new, inventive, and industrially applicable formulation or process, that specific innovation may qualify for patent protection, subject to applicable law.

The company's use of biological resources and associated traditional knowledge may also trigger access and benefit-sharing obligations.

5. Major challenges

Traditional knowledge may exist only in oral form.

Patent examiners may lack access to local-language documentation.

Communities may not have sufficient resources to challenge foreign patents.

Commercial exploitation may occur without fair benefit-sharing.

Existing intellectual property systems may not adequately recognize collective community ownership.

Documentation may protect knowledge defensively but may also expose sensitive traditional practices to misuse.

Conclusion

Protection of Traditional Knowledge in Patents is an essential aspect of intellectual property law and biotechnology governance. It prevents the misappropriation of traditional knowledge while preserving opportunities for genuine scientific innovation.

The turmeric, neem, and Basmati disputes demonstrate that traditional knowledge can be used to challenge improper patent claims. India's Patents Act, 1970, particularly Section 3(p), and the Traditional Knowledge Digital Library provide important mechanisms for preventing biopiracy.

The fundamental principle is that traditional knowledge should not be converted into an exclusive private monopoly merely because it has been rediscovered or documented by a modern researcher. Genuine innovation may be protected, but existing community knowledge must be respected and safeguarded.
