Who Owns Innovation in Plant Breeding?
The Unresolved Question of ‘Essentially Derived Varieties’ under India’s PPV&FR Act, 2001
By S.Karthikeyan
Introduction
Imagine a plant breeder who spends fifteen years and considerable public or private capital developing a high-yielding, disease-resistant variety of wheat; she registers it under the Protection of Plant Varieties and Farmers’ Rights Act, 2001 (PPV&FR Act), confident that the law recognizes her intellectual investment. A year later, a competing firm introduces a new variety to the market; it shares close to ninety per cent of its genetic profile with hers, performs identically in agronomic trials, and retains every commercially significant trait she bred into her variety. The competitor has made a single modification to a non-essential characteristic, a marginal change in kernel colour, and files an independent registration, claiming an entirely new variety. Does this constitute legitimate scientific innovation? Or is it the appropriation of fifteen years of breeding effort, repackaged under a different name?
This scenario illustrates the most consequential and least examined ambiguity in Indian plant variety protection law: the legal treatment of Essentially Derived Varieties (EDVs). The PPV&FR Act, 2001, acknowledges that certain varieties are so genetically proximate to a protected parent variety that they cannot be treated as wholly independent innovations. It designates these as ‘essentially derived’ and, in principle, requires the consent of the original breeder before such a variety is commercially exploited. In practice, however, the Act provides no method for determining when derivation reaches the threshold of ‘essential’ derivation in such no statutory definition, no scientific benchmark, no regulatory guideline, and no judicial test.
The central question this article addresses is precisely the one the Act leaves unanswered: at what point does improvement become innovation, and at what point does it become appropriation? This is not a philosophical question about the nature of creativity. It is a precise intellectual property question about the legal threshold at which the second breeder’s rights are limited by the first breeder’s prior rights. The absence of a clear answer affects IP ownership, breeders’ rights, infringement analysis, licensing obligations, commercial seed innovation, and the direction of future plant breeding research in one of the world’s most agriculturally significant nations. At what point does improvement become innovation, and at what point does it become appropriation? The PPV&FR Act, 2001 raises this question with precision. It answers it with silence.
Understanding Plant Variety Protection and Essentially Derived Varieties
Plant variety protection (PVP) is a form of intellectual property right tailored to the unique biology of agricultural innovation. Unlike patents, which protect inventions through functional claims, PVP protects the living organism itself the plant variety as a stable, identifiable biological entity and recognizes that the process of developing such a variety through selection, crossing, and stabilization represents a form of creative and technical investment deserving legal recognition. Internationally, PVP is governed by the International Union for the Protection of New Varieties of Plants (UPOV), whose 1991 Act provides the principal international framework for plant breeders’ rights.
India enacted the PPV&FR Act, 2001, to fulfil its obligations under Article 27(3)(b) of the TRIPS Agreement, which requires WTO members to provide protection for plant varieties either through patents, through an effective sui generis system, or a combination of both. India chose the sui generis route and designed the PPV&FR Act, 2001, as a hybrid that balances breeders’ rights with farmers’ rights, traditional knowledge protection, and benefit-sharing obligations, a design that has attracted wide comparative attention. The Act grants breeders a registration-based right to control the production, sale, marketing, import, and export of propagating material of their registered variety for a fixed term.
The concept of Essentially Derived Varieties was introduced into international plant variety protection law through Article 14(5) of the UPOV Act, 1991. The rationale was both pragmatic and principled. Advances in biotechnology, particularly mutation breeding, backcross programs, and eventually transgenic modification, had made it technically possible to produce a new variety from an existing protected variety through minimal genetic modification while retaining virtually all of the original variety’s commercial value. Without an EDV provision, second comers could free-ride on the first breeder’s investment simply by applying a technically permissible modification and claiming independent variety status, entirely without consent or royalty obligation. The UPOV-EDV concept was designed to prevent this outcome by extending the first breeder’s rights over varieties that, despite being formally distinct, are essentially derived from the first breeder’s protected variety.
India adopted this concept in Section 2(j) of the PPV&FR Act, 2001, which defines an essentially derived variety as one that: (i) is predominantly derived from the initial variety, or from a variety itself predominantly derived from the initial variety, while retaining the expression of the essential characteristics resulting from the genotype of the initial variety; (ii) is clearly distinguishable from the initial variety; and (iii) except for differences resulting from the act of derivation, conforms to the initial variety in the expression of its essential characteristics. Section 28 of the Act extends the registered breeder’s rights to EDVs, meaning that a breeder who seeks to commercialize an EDV must first obtain the consent of the original variety’s registered breeder. In principle, this is a robust and carefully constructed protection. Its entire operation, however, depends on a prior determination: has the candidate variety actually crossed the threshold into essential derivation? And this is precisely the question the Act does not answer.
The Problem with ‘Predominantly Derived’: An Undefined Operative Term
Section 2(j)(i) of the PPV&FR Act specifies that an EDV is one that is ‘predominantly derived’ from an initial variety. The word ‘predominantly’ is the provision’s entire operative standard, and it is wholly undefined. Neither the Act, the Plant Varieties (Protection and Registration) Rules, 2003, nor any notification or guideline issued by the Protection of Plant Varieties and Farmers’ Rights Authority (PPV&FRA) specifies what degree of genetic or phenotypic similarity constitutes predominance for any species or category of plant. This is not a gap that can be resolved by ordinary statutory interpretation: determining whether one biological organism is predominantly derived from another is, at its core, an empirical question that cannot be answered by reading the statutory text more carefully. Section 2(j) of the PPV&FR Act, 2001 states:
“Essentially derived variety” in relation to a variety shall mean a variety which:- (i) is predominantly derived from such initial variety, or from a variety that itself is predominantly derived from such initial variety, while retaining the expression of the essential characteristics that result from the genotype or combination of genotypes of such initial variety; (ii) is clearly distinguishable from such initial variety; and (iii) except for the differences which result from the act of derivation, conforms to such initial variety in the expression of the essential characteristics that result from the genotype or combination of genotypes of such initial variety.”
The practical consequences of this definitional lacuna are severe and extend across multiple dimensions of plant variety IP. Consider the following questions that arise in any EDV dispute, and that current Indian law leaves entirely without guidance:
First, what percentage of genetic similarity is sufficient to establish predominant derivation? The UPOV community has consistently acknowledged that no single numerical threshold is biologically appropriate for all species; a similarity coefficient that denotes near-identity in rice may indicate considerable divergence in a crop with lower inherent genetic diversity. Yet some threshold must be identified before the provision can be applied. Is 80% genetic identity sufficient? Is 90%? Is 95%? The Act provides no answer, and the PPV&FRA has issued no species-specific guidance.
Second, should predominant derivation be assessed by molecular marker analysis techniques such as Simple Sequence Repeat (SSR) analysis, Single Nucleotide Polymorphism (SNP) profiling, or Diversity Arrays Technology (DArT), or by morphological DUS criteria (Distinctness, Uniformity, Stability), the standard used in variety registration? These two methods can and often do produce divergent results. A variety may be morphologically distinguishable while being molecularly nearly identical to the initial variety, or vice versa. The Act provides no hierarchy of evidentiary methods, leaving tribunals and courts without a methodology for resolving conflicts between morphological and molecular assessments.
Third, where does the burden of proof lie? Must the initial breeder affirmatively establish that the candidate variety is predominantly derived from theirs, or must the second breeder demonstrate independent genetic origin? The allocation of this burden is foundational to litigation strategy and outcome, yet the Act and Rules are entirely silent on it.
Fourth, how should the provision be applied to varieties produced by modern biotechnological methods? A variety produced by inserting a single transgene into an existing protected variety may share 99.9% of the genome of the initial variety while embodying a commercially significant and independently patentable new trait. Is such a variety an EDV, requiring the original breeder’s consent? Or does the technological independence of the inserted gene justify treating it as an independent variety? The Act’s silence on this point creates a structural uncertainty that will only grow as CRISPR and other precision breeding technologies become more widely deployed in Indian plant breeding.
A legal standard whose entire operative criterion is the word ‘predominantly’ with no statutory, regulatory, or judicial gloss on what predominantly means in a biological context is, in practical terms, no standard at all. What institutional body should make the EDV determination? The PPV&FRA has jurisdiction over registration disputes, but the procedural framework and evidentiary standards applicable to inter-party EDV ownership disputes before the Authority are not established in the Act or Rules. The result is that the EDV provision, while correct in legislative intent, is effectively unenforceable in practice: a first breeder who believes their variety has been essentially derived from another has no clear legal framework within which to vindicate that right.

The Missing Jurisprudence: What Indian Courts Have and Have Not Addressed
A robust body of judicial decisions interpreting Section 2(j) with analytical rigor and establishing a workable EDV determination test would, in principle, compensate for some of the Act’s legislative omissions. No such body of decisions exists. Three cases are typically cited as the most significant in PPV&FR litigation, but none engages substantively with the EDV determination problem.
In Pioneer Overseas Corporation v. Union of India (2019), the dispute arose from the registrability of maize hybrid varieties and procedural compliance with the PPV&FR Act’s registration requirements. The Court examined the PPV&FRA’s administrative functions and certain evidentiary aspects of the registration process, but no substantive question about what constitutes essential derivation was placed before it. The decision’s contribution to EDV jurisprudence is, accordingly, negligible.
In Prabhat Agri Biotech Ltd. v. Registrar of Plant Varieties (2016), the core dispute concerned the denial of registration to a plant variety and raised questions about the procedural authority of the Registrar. While the case touched on aspects of breeders’ rights and the standards applicable to registration decisions, it did not present an EDV ownership conflict and therefore generated no analysis of the predominant derivation standard.
In Nuziveedu Seeds Pvt. Ltd. v. PPVFR Authority (2023), the factual context involved competing variety claims in the commercially significant cotton seed sector, and the case came closest to raising EDV-type issues. However, the Court’s analysis was oriented toward regulatory and administrative questions rather than the substantive scientific and legal threshold of essential derivation. No determination of what genetic or morphological similarity level would constitute predominant derivation was made, and no evidentiary framework was established.
The pattern across all three cases is consistent: Indian courts and tribunals have not yet been presented with a case that directly and squarely raises the EDV determination, the question of what constitutes predominant derivation, how it is to be measured, what evidence is sufficient to establish it, and who bears the burden of proof. Until such a case generates a reasoned judicial decision, the PPV&FR Act’s EDV provision will remain a norm in text only, without a method of application.
How Other Jurisdictions Address EDV Determination: A Comparative Analysis
The International experience with EDV determination demonstrates that the challenge of defining predominant derivation scientifically is not unique to India, but it also demonstrates that meaningful regulatory and scientific progress has been made in comparative jurisdictions that India has not yet followed.
The UPOV, 1991, framework, through the work of the UPOV Technical Committee, has produced guidance material identifying that EDV determination involves a two-step process: first, an assessment of genetic conformity establishing that the candidate variety predominantly conforms to the initial variety in its essential characteristics; second, a determination of whether the differences between the two varieties are sufficiently accounted for by the act of derivation itself. Crucially, UPOV has acknowledged that the specific methodology, whether molecular markers, morphological characteristics, or a combination, is species-specific and should be calibrated at the national or regional level through consultation with scientific bodies.
The European Union Community Plant Variety Rights system, administered by the Community Plant Variety Office (CPVO), represents the most developed regulatory framework for EDV assessment currently in operation internationally. The CPVO has developed detailed EDV assessment protocols that make explicit use of molecular marker data, specifying minimum numbers of genetic loci to be assessed, the formulae by which genetic similarity coefficients are to be calculated, and the manner in which molecular results are to be weighed against morphological assessments. The EU approach provides a replicable institutional model that other jurisdictions, including India, could adapt with appropriate modifications for local species diversity.
Australia’s Plant Breeders’ Rights Act, 1994, administered by IP Australia, engages with EDV determination through a combination of statutory guidance and administrative practice, providing more clarity on the types of evidence admissible to establish essential derivation than its Indian counterpart. The Plant Breeders’ Rights Office has issued material on the assessment process and the evidential standards applicable in EDV disputes.
In the United States, plant variety protection under the Plant Variety Protection Act, 1970, has developed EDV assessment criteria that draw on genetic distance calculations. The US Plant Variety Protection Office has, through administrative practice, built up a body of guidance that gives breeders reasonable certainty about the types of evidence and methods of analysis relevant to EDV determinations.
What these international frameworks share is a recognition that EDV determination is a mixed legal-scientific question that requires both statutory clarity and institutional scientific capacity. The CPVO’s detailed protocols, Australia’s administrative guidance, and the UPOV Technical Committee’s species-specific methodology documents collectively demonstrate that this problem is tractable, it has been addressed with reasonable effectiveness in multiple jurisdictions. India’s PPV&FR Act provides neither the statutory clarity nor the institutional scientific framework that these comparative examples show to be necessary.
Recommendations for Legislative and Regulatory Reform
Addressing the EDV determination gap requires coordinated action at three levels: legislative, regulatory, and judicial.
At the legislative level, the most immediate need is an amendment to Section 2(j) of the PPV&FR Act to supplement the term ‘predominantly derived’ with criteria against which predominance is to be assessed. Drawing on the UPOV and CPVO approaches, a workable model would define predominant derivation as a situation where: (a) the genetic constitution of the candidate variety is substantially derived from the initial variety, such that the essential characteristics of the candidate variety result principally from the genotype or combination of genotypes of the initial variety; and (b) the differences between the candidate variety and the initial variety can be adequately accounted for by the act of derivation itself, rather than by an independent breeding contribution of substantive genetic significance. This formulation avoids a single numerical threshold which would be inappropriate given species diversity while providing a legal criterion with meaningful content that courts and the PPV&FRA can apply.
At the regulatory level, the PPV&FRA should exercise its delegated authority under the Act to issue Regulations on EDV Assessment. These Regulations should specify, at a minimum: (i) the types of scientific evidence admissible to establish essential derivation, distinguishing between molecular marker analysis and morphological DUS assessment and establishing their relative weight; (ii) the minimum number of genetic loci to be assessed in any molecular marker analysis submitted as evidence of derivation; (iii) the method of calculating genetic similarity coefficients and the standard of similarity that gives rise to a prima facie presumption of predominant derivation for key crop species; and (iv) the burden of proof framework applicable in EDV disputes before the PPVFRA and, on appeal, before the courts. These Regulations should be developed in formal consultation with the Indian Council of Agricultural Research (ICAR), the National Bureau of Plant Genetic Resources, and representatives of both the private seed industry and farmer seed networks, to ensure that the scientific standards adopted are appropriately calibrated to the biological reality of Indian crop diversity.
At the judicial level, the Plant Varieties Protection Appellate Tribunal (PVPAT), when constituted with adequate scientific capacity, and the High Courts hearing PPV&FR matters should develop a practice of seeking independent scientific expert testimony in EDV disputes and should produce reasoned, published decisions that engage substantively with the EDV determination methodology. Published decisions in EDV cases would, over time, constitute a body of Indian EDV jurisprudence that provides increasing certainty to breeders, seed companies, and research institutions even in the absence of legislative or regulatory specification.
Finally, the burden of proof in EDV disputes should be codified with clarity. The party claiming that a registered variety is essentially derived from another, typically the initial breeder, should bear the burden of establishing predominant derivation on the balance of probabilities. Once a prima facie case is made through molecular marker analysis showing similarity above a prescribed threshold for the relevant species, the burden should shift to the second breeder to demonstrate, by credible scientific evidence, that their variety has an independent genetic origin sufficient to displace the presumption of predominant derivation.
Conclusion
The PPV&FR Act, 2001, represents a genuinely ambitious achievement in Indian intellectual property law. It introduced a comprehensive plant variety protection regime suited to India’s agricultural complexity, balanced breeders’ incentives with farmers’ rights, and engaged seriously with the challenge of incorporating the UPOV, 1991, EDV concept into a sui generis framework that serves India’s distinct interests. The EDV provision itself reflects a sophisticated understanding of the risk that minimal modification of a protected variety could be deployed as a mechanism for circumventing breeders’ rights, a risk that has only grown as plant biotechnology has matured.
India’s plant breeding sector is technologically capable and commercially significant. It deserves a legal framework for EDV determination that matches that capacity, clear in its standards, transparent in its methodology, and accessible in its institutional framework. India’s seed industry is large, its breeding research base is substantial, and its agricultural technology adoption is accelerating. The frequency of EDV-type situations will increase as precision breeding tools become standard practice. Without a clear legal framework, each such situation will generate uncertainty about IP ownership, potential for dispute, and a chilling effect on the cumulative innovation in plant breeding that the PPV&FR Act’s breeders’ rights provisions were designed to incentivize.
Developing that framework through legislative amendment to Section 2(j), through PPV&FRA Regulations on EDV Assessment, and through the gradual accumulation of reasoned judicial decisions is one of the most urgent and least addressed tasks in Indian intellectual property policy. The question of who owns innovation in plant breeding will not resolve itself. Nor, as this article has argued, can the PPV&FR Act, as presently drafted, resolve it. The first step toward a solution is the precise identification of the problem. That identification is the purpose and the argument of this analysis.
