Can Traditional Knowledge Be Patented in India?

Can Traditional Knowledge Be Patented in India?.  
Traditional knowledge represents the accumulated practices, observations and innovations developed and transmitted across generations. In India, it includes medicinal knowledge, agricultural practices, herbal remedies and indigenous techniques. Although it may have substantial scientific and commercial value, traditional knowledge presents distinctive challenges for patent law. Section 3(p) of the Patents Act, 1970 excludes an invention which, in effect, is traditional knowledge or merely an aggregation or duplication of known properties of traditionally known components. This article examines the statutory framework, the role of the Traditional Knowledge Digital Library (TKDL), the turmeric and neem patent controversies, and the relationship between patentability, biodiversity regulation and biopiracy.

Introduction

Traditional knowledge is an important part of India’s cultural and scientific heritage. Communities have developed and preserved knowledge concerning medicinal plants, agricultural techniques, food preservation, natural dyes and other practical applications of biological resources. Such knowledge may be transmitted orally, recorded in classical texts or maintained through community practices.
As researchers and businesses investigate traditional remedies and biological resources, an important intellectual property question arises: can a person obtain a patent over knowledge that has already existed within a community for generations?
Indian patent law generally prevents a patent from being granted for traditional knowledge itself or for a claim that merely reproduces the known properties of traditionally known components. The position is more nuanced where research based on traditional knowledge results in a genuinely new technical invention. The key distinction is between impermissibly claiming existing knowledge and protecting a new invention that independently satisfies the statutory requirements.

Legal Framework Under the Patents Act, 1970

Section 3(p): The principal exclusion

Section 3(p) of the Patents Act, 1970 provides that the following are not inventions within the meaning of the Act:
“an invention which in effect, is traditional knowledge or which is an aggregation or duplication of known properties of traditionally known component or components.”
The provision addresses two broad situations: (i) an invention that is, in substance, traditional knowledge already known to a community; and (ii) a claim that merely aggregates or duplicates known properties of traditionally known components without establishing a patentable invention.
For example, the traditional use of turmeric for wound healing cannot ordinarily be patented merely by restating that use in a patent application. Likewise, simply claiming the established
 
pesticidal properties of neem would face serious difficulty under Section 3(p). The provision helps prevent existing community knowledge from being converted into an unjustified exclusive right.

Section 2(1)(j): Definition of an invention

Section 2(1)(j) defines an invention as a new product or process involving an inventive step and capable of industrial application. An applicant must therefore establish novelty, an inventive step and industrial applicability, while also avoiding the exclusions in Sections 3 and 4 of the Act. Technical language or a newly drafted description does not make old knowledge new.

Other relevant provisions

Section 3(d) excludes certain subject matter involving, among other things, the mere discovery of a new form of a known substance without the required enhancement of efficacy, and the mere discovery of a new property or new use for a known substance, subject to the exact statutory wording.
Section 10 governs the contents of patent specifications, including the description and claims.
Sections 25(1)(k) and 25(2)(k) recognise anticipation by knowledge, oral or otherwise, available within a local or indigenous community in India or elsewhere as grounds for pre-grant and post-grant opposition, respectively.
Section 64(1)(q) recognises the same kind of community knowledge as a ground for revocation.
These provisions matter at different stages: during examination, in opposition proceedings and in a later revocation action. The precise evidentiary record and the applicable procedural requirements remain important.

Can an Invention Based on Traditional Knowledge Be Patented?

The exclusion of traditional knowledge does not mean that every invention inspired by a traditional practice is automatically unpatentable. The question is whether the particular claims disclose a patentable technical contribution beyond what was already known.
Consider a hypothetical example: a community has long used a plant extract for a particular purpose, and a researcher later develops a technically new process to produce a stable formulation from that extract. The process or formulation would not qualify for a patent merely because it is described as scientifically developed. Its claims must be assessed against the prior art and the requirements of novelty, inventive step and industrial applicability, as well as any applicable exclusions.
Depending on the facts, a genuinely new process or formulation may be patentable. Conversely, a simple mixture of known ingredients, a mere discovery of a known property, or a routine modification may fail. Patentability depends on the substance and scope of the claims, not simply on the fact that research has been conducted.

The Turmeric Patent Controversy

The turmeric controversy is a widely cited international example of the difficulty of distinguishing existing traditional knowledge from a new invention. In 1995, the United States Patent and Trademark Office (USPTO) granted US Patent No. 5,401,504 concerning the use of turmeric in wound healing.
The Council of Scientific and Industrial Research (CSIR), India, sought re-examination and supplied evidence that the claimed use was already known, including published material. In 1997, the USPTO cancelled the challenged claims following re-examination in light of the prior art.
 
Legal significance: the episode illustrates that documented traditional practices and earlier publications can be relevant prior art. It was a US patent-office proceeding, not a judgment of an Indian court, and should be cited as a foreign patent controversy rather than binding Indian precedent.

The Neem Patent Controversy

Neem (Azadirachta indica) has long been used in India for various agricultural, household and medicinal purposes. In 1994, the European Patent Office (EPO) granted European Patent No. 0 436 257 concerning a method of controlling fungi on plants using a hydrophobic-extracted neem-oil formulation, with W. R. Grace and the United States Department of Agriculture among the original applicants.
Opponents challenged the patent on grounds including lack of novelty and inventive step, relying on evidence concerning prior knowledge and use. The EPO Opposition Division revoked the patent in 2000. The revocation was subsequently appealed; in decision T 0416/01 dated 8 March 2005, the EPO Board of Appeal dismissed the appeal, leaving the revocation in place.
Legal significance: the neem proceedings demonstrate the importance of prior-art evidence in assessing claims relating to known biological materials and their uses. As with turmeric, the proceedings were before foreign patent authorities, not an Indian court.

The Traditional Knowledge Digital Library (TKDL)

India developed the Traditional Knowledge Digital Library (TKDL) to help address the problem of traditional knowledge being overlooked during patent examination. The initiative, developed through collaboration involving CSIR and government departments responsible for traditional systems of medicine, records selected traditional medicinal knowledge in a structured, searchable format.
Traditional knowledge may be preserved in Sanskrit, Hindi, Tamil and other languages or in texts unfamiliar to patent examiners abroad. Structured documentation can make relevant prior art more accessible to authorised examiners and assist in identifying claims that lack novelty or otherwise improperly appropriate existing knowledge.
The TKDL is principally a defensive protection mechanism. It can help prevent unjustified patents, but it does not itself create a comprehensive proprietary right for every traditional community or automatically resolve questions of consent, access or benefit-sharing.

The Biological Diversity Act, 2002

Patentability is not the only legal issue where traditional knowledge is associated with biological resources. The Biological Diversity Act, 2002, as amended in 2023, establishes a separate framework for access to biological resources and associated traditional knowledge, including benefit-sharing obligations where applicable.
Section 6 addresses intellectual property applications involving research or information on biological resources accessed from India, including associated traditional knowledge. Under the amended framework, the applicable requirement may involve prior approval from the National Biodiversity Authority (NBA), registration, or approval at commercialisation, depending on the category of person and the statutory conditions. The Act and its current rules should be checked for the particular applicant and activity.
A patent applicant should therefore assess patentability and biodiversity-law compliance separately. Satisfying the patentability tests does not, by itself, establish compliance with every applicable access, disclosure or benefit-sharing requirement.

Biopiracy and Protection of Community Interests

Biopiracy is commonly used to describe the unauthorised or inequitable appropriation or commercial exploitation of biological resources and associated traditional knowledge, particularly where the interests and contributions of source communities are disregarded.
The concern is not that all commercial research into traditional practices is improper. Research can generate useful innovations. Problems arise when existing knowledge is represented as new, source information is mishandled, or commercial benefits are obtained without compliance with applicable legal obligations.
Relevant safeguards include: (i) improved documentation of prior art; (ii) effective use of opposition  and  revocation  procedures;  (iii)  compliance  with  biodiversity  and access-and-benefit-sharing requirements; and (iv) meaningful consideration of the interests of communities that have maintained the knowledge.
Patent law is territorial. A patent granted abroad is not automatically invalid because Indian law excludes traditional knowledge. Any challenge must proceed under the law and procedures of the jurisdiction where the application or patent is pending or granted.

Is the Existing Framework Sufficient?

India has developed significant safeguards, including Section 3(p), opposition and revocation provisions, the TKDL and biodiversity legislation. However, important challenges remain.
First, not all traditional knowledge is documented. Oral knowledge may be difficult to establish as prior art without reliable evidence of its content and existence at the relevant date. Second, knowledge may be shared across several communities or countries, raising questions about origin, custodianship and benefit-sharing. Third, defensive documentation does not necessarily give communities positive rights to control commercial use or obtain a share of resulting benefits.
Finally, patent examination is territorial and depends on the applicable legal system. Stronger documentation, international cooperation, fair benefit-sharing arrangements and community participation are therefore important complements to patent law.

Conclusion

Traditional knowledge, as such, cannot ordinarily be patented in India. Section 3(p) of the Patents Act, 1970 expressly excludes an invention that is, in effect, traditional knowledge or merely an aggregation or duplication of known properties of traditionally known components. The opposition and revocation provisions also recognise community knowledge as potentially relevant prior art.
The turmeric and neem controversies show the practical importance of identifying prior knowledge during patent examination, while the TKDL offers a mechanism for making documented traditional medicinal knowledge more accessible. Yet the law does not prohibit all research inspired by traditional knowledge: a genuinely new technical invention may qualify if it satisfies the statutory requirements and avoids applicable exclusions. Where biological resources are involved, biodiversity-law obligations must also be considered.
The appropriate objective is to encourage genuine innovation without granting unjustified monopolies over knowledge that communities have preserved and developed over generations.

Traditional knowledge represents the accumulated practices, observations and innovations developed and transmitted across generations. In India, it includes medicinal knowledge, agricultural practices, herbal remedies and indigenous techniques. Although it may have substantial scientific and commercial value, traditional knowledge presents distinctive challenges for patent law. Section 3(p) of the Patents Act, 1970 excludes an invention which, in effect, is traditional knowledge or merely an aggregation or duplication of known properties of traditionally known components. This article examines the statutory framework, the role of the Traditional Knowledge Digital Library (TKDL), the turmeric and neem patent controversies, and the relationship between patentability, biodiversity regulation and biopiracy.

Introduction

As researchers and businesses investigate traditional remedies and biological resources, an important intellectual property question arises: can a person obtain a patent over knowledge that has already existed within a community for generations?

Indian patent law generally prevents a patent from being granted for traditional knowledge itself or for a claim that merely reproduces the known properties of traditionally known components. The position is more nuanced where research based on traditional knowledge results in a genuinely new technical invention. The key distinction is between impermissibly claiming existing knowledge and protecting a new invention that independently satisfies the statutory requirements.

Legal Framework Under the Patents Act, 1970
1. Section 3(p): The principal exclusion

Section 3(p) of the Patents Act, 1970 provides that the following are not inventions within the meaning of the Act:

“an invention which in effect, is traditional knowledge or which is an aggregation or duplication of known properties of traditionally known component or components.”

The provision addresses two broad situations: (i) an invention that is, in substance, traditional knowledge already known to a community; and (ii) a claim that merely aggregates or duplicates known properties of traditionally known components without establishing a patentable invention.

For example, the traditional use of turmeric for wound healing cannot ordinarily be patented merely by restating that use in a patent application. Likewise, simply claiming the established

pesticidal properties of neem would face serious difficulty under Section 3(p). The provision helps prevent existing community knowledge from being converted into an unjustified exclusive right.

Section 2(1)(j): Definition of an invention

Section 2(1)(j) defines an invention as a new product or process involving an inventive step and capable of industrial application. An applicant must therefore establish novelty, an inventive step and industrial applicability, while also avoiding the exclusions in Sections 3 and 4 of the Act. Technical language or a newly drafted description does not make old knowledge new.

Other relevant provisions

Section 10 governs the contents of patent specifications, including the description and claims.

Sections 25(1)(k) and 25(2)(k) recognise anticipation by knowledge, oral or otherwise, available within a local or indigenous community in India or elsewhere as grounds for pre-grant and post-grant opposition, respectively.

Section 64(1)(q) recognises the same kind of community knowledge as a ground for revocation.

These provisions matter at different stages: during examination, in opposition proceedings and in a later revocation action. The precise evidentiary record and the applicable procedural requirements remain important.

Can an Invention Based on Traditional Knowledge Be Patented?

Consider a hypothetical example: a community has long used a plant extract for a particular purpose, and a researcher later develops a technically new process to produce a stable formulation from that extract. The process or formulation would not qualify for a patent merely because it is described as scientifically developed. Its claims must be assessed against the prior art and the requirements of novelty, inventive step and industrial applicability, as well as any applicable exclusions.

Depending on the facts, a genuinely new process or formulation may be patentable. Conversely, a simple mixture of known ingredients, a mere discovery of a known property, or a routine modification may fail. Patentability depends on the substance and scope of the claims, not simply on the fact that research has been conducted.

The Turmeric Patent Controversy

The Council of Scientific and Industrial Research (CSIR), India, sought re-examination and supplied evidence that the claimed use was already known, including published material. In 1997, the USPTO cancelled the challenged claims following re-examination in light of the prior art.

Legal significance: the episode illustrates that documented traditional practices and earlier publications can be relevant prior art. It was a US patent-office proceeding, not a judgment of an Indian court, and should be cited as a foreign patent controversy rather than binding Indian precedent.

The Neem Patent Controversy

Opponents challenged the patent on grounds including lack of novelty and inventive step, relying on evidence concerning prior knowledge and use. The EPO Opposition Division revoked the patent in 2000. The revocation was subsequently appealed; in decision T 0416/01 dated 8 March 2005, the EPO Board of Appeal dismissed the appeal, leaving the revocation in place.

Legal significance: the neem proceedings demonstrate the importance of prior-art evidence in assessing claims relating to known biological materials and their uses. As with turmeric, the proceedings were before foreign patent authorities, not an Indian court.

The Traditional Knowledge Digital Library (TKDL)

Traditional knowledge may be preserved in Sanskrit, Hindi, Tamil and other languages or in texts unfamiliar to patent examiners abroad. Structured documentation can make relevant prior art more accessible to authorised examiners and assist in identifying claims that lack novelty or otherwise improperly appropriate existing knowledge.

The TKDL is principally a defensive protection mechanism. It can help prevent unjustified patents, but it does not itself create a comprehensive proprietary right for every traditional community or automatically resolve questions of consent, access or benefit-sharing.

The Biological Diversity Act, 2002

Section 6 addresses intellectual property applications involving research or information on biological resources accessed from India, including associated traditional knowledge. Under the amended framework, the applicable requirement may involve prior approval from the National Biodiversity Authority (NBA), registration, or approval at commercialisation, depending on the category of person and the statutory conditions. The Act and its current rules should be checked for the particular applicant and activity.

A patent applicant should therefore assess patentability and biodiversity-law compliance separately. Satisfying the patentability tests does not, by itself, establish compliance with every applicable access, disclosure or benefit-sharing requirement.

Biopiracy and Protection of Community Interests

The concern is not that all commercial research into traditional practices is improper. Research can generate useful innovations. Problems arise when existing knowledge is represented as new, source information is mishandled, or commercial benefits are obtained without compliance with applicable legal obligations.

Relevant safeguards include: (i) improved documentation of prior art; (ii) effective use of opposition and revocation procedures; (iii) compliance with biodiversity and access-and-benefit-sharing requirements; and (iv) meaningful consideration of the interests of communities that have maintained the knowledge.

Patent law is territorial. A patent granted abroad is not automatically invalid because Indian law excludes traditional knowledge. Any challenge must proceed under the law and procedures of the jurisdiction where the application or patent is pending or granted.

Is the Existing Framework Sufficient?

India has developed significant safeguards, including Section 3(p), opposition and revocation provisions, the TKDL and biodiversity legislation. However, important challenges remain.

First, not all traditional knowledge is documented. Oral knowledge may be difficult to establish as prior art without reliable evidence of its content and existence at the relevant date. Second, knowledge may be shared across several communities or countries, raising questions about origin, custodianship and benefit-sharing.
