UPOV: Shaping the Protection of Plant Breeders’ Rights Globally

When a plant breeder spends years developing a new crop variety – investing time, money, and scientific expertise – what stops a competitor from simply taking that variety and selling it commercially without any compensation? Before 1961, the honest answer was: very little. The International Union for the Protection of New Varieties of Plants (UPOV) was created precisely to fix this gap, establishing the world’s first dedicated international framework for protecting plant breeders’ intellectual property. Understanding how UPOV came to be, and how it has evolved, is essential for anyone studying IP rights in the context of agriculture and international trade.

The problem UPOV was created to solve 🔗

Plant breeding has existed for millennia, but its transformation into a modern, science-driven industry is relatively recent. By the early 20th century, advances in genetics and agronomy had made systematic plant breeding commercially viable. Private companies began investing heavily in developing improved crop varieties – higher-yielding wheat, disease-resistant tomatoes, ornamental flowers with novel characteristics. But there was a fundamental problem: seeds and cuttings can be reproduced. Once a new variety was released into the market, anyone could multiply and sell it, leaving the original breeder with no way to recover their investment.

Traditional patent law offered no satisfactory solution. Plant breeders in the 1950s found that patenting was not a viable path – patent criteria like “non-obviousness” and “industrial application” did not translate well to living plant material, and extending patents to plants risked undermining core patent law principles. The commercial breeders’ trade association ASSINSEL concluded at its 1956 Congress that a separate, purpose-built international instrument was needed. It requested the French government to host an international conference to develop new rules specifically for plant varieties.

The 1957 Paris conference and the birth of UPOV 🔗

The international conference convened in Paris in May 1957, bringing together representatives from Western European governments, breeders’ associations, and IP organizations including ASSINSEL, the International Association for the Protection of Intellectual Property (AIPPI), and the International Chamber of Commerce. The Paris meeting established the basic principles of what would become a new category of intellectual property right, tailor-made for plant varieties. After further negotiations, UPOV was formally established on December 2, 1961, when the International Convention for the Protection of New Varieties of Plants was signed. The founding members were six Western European countries: Belgium, France, Germany, Italy, the Netherlands, and the United Kingdom.

The 1961 Convention introduced a sui generis (meaning “of its own kind”) system of intellectual property protection – distinct from patents, trademarks, or copyright, and specifically designed around the biological realities of plant breeding. This system came to be known as Plant Breeders’ Rights (PBR) or Plant Variety Protection (PVP).

Core principles of the UPOV system 🔗

At the heart of the UPOV Convention is a set of eligibility criteria that a new plant variety must satisfy before it qualifies for protection. These criteria have remained consistent across all versions of the Convention and are collectively referred to as the DUS test:

Distinctness (D): The variety must be clearly distinguishable from any other variety whose existence is a matter of common knowledge. It must differ in at least one important characteristic.

Uniformity (U): Plants of the variety must show consistent traits. Variation among individual plants must remain within acceptable limits.

Stability (S): The variety’s distinguishing characteristics must remain the same across successive generations of reproduction.

In addition to DUS, the variety must also be novel – meaning it has not been commercially sold or otherwise made available to the public before a specified cut-off period prior to the application date. It is important to note that UPOV defines novelty in terms of commercialisation, not in terms of whether the variety previously existed in nature.

The UPOV Convention also built in two important exceptions from the very beginning. The breeder’s exemption allows any breeder to freely use a protected variety to develop a new one – recognising that access to existing genetic material is essential for continued innovation. The farmer’s privilege (in earlier acts) permitted farmers to save seeds from their own harvest for replanting on their own holdings.

Revisions of the UPOV Convention: 1972, 1978, and 1991 🔗

The UPOV Convention has been revised three times – in 1972, 1978, and 1991 – with each revision strengthening the rights granted to plant breeders.

The 1972 amendment 🔗

The 1972 revision was primarily administrative, adjusting the financial contributions of member states. It did not substantially alter the substantive rights under the Convention and is often referred to as the “Additional Act” rather than a full revision.

The 1978 Act 🔗

The 1978 revision was more substantive. It clarified the scope of breeders’ exclusive rights and introduced the concept of “national treatment,” under which breeders from any member country are entitled to the same protection available to nationals of other member states. The 1978 Act also explicitly permitted member states to restrict breeders’ rights for reasons of public interest, provided breeders received equitable remuneration. Under the 1978 Act, the farmer’s privilege to save and exchange seeds was implicitly recognised, because the breeder’s exclusive right extended only to production for marketing purposes.

The 1991 Act 🔗

The 1991 revision was the most significant overhaul of the Convention. It substantially expanded the scope of breeders’ rights in several ways. The most notable change was the introduction of the concept of Essentially Derived Varieties (EDV) – varieties that are predominantly derived from a protected variety but with minor modifications. Under UPOV 1991, breeders of EDVs must obtain authorisation from the original breeder, preventing a common practice of making cosmetic changes to bypass protection.

The 1991 Act also extended breeders’ rights to cover harvested material in certain circumstances, required protection to extend to all plant genera and species within ten years of a country’s accession, and set minimum protection periods: at least 20 years from grant for most crops and at least 25 years for trees and vines. The farmer’s privilege, which had been broad under the 1978 Act, became a narrower optional exception under 1991 – farmers could only save seeds “within reasonable limits and subject to safeguarding the legitimate interests of the breeder,” which in practice often means paying license fees.

UPOV’s global expansion: the role of the TRIPS Agreement 🔗

For nearly three decades after its founding, UPOV remained a largely European club. By 1990, only 19 countries had joined the Convention, with South Africa being the only member from the Southern Hemisphere. This changed dramatically with the adoption of the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) in 1994 as part of the establishment of the World Trade Organization (WTO).

Article 27.3(b) of TRIPS requires WTO members to provide protection for plant varieties either by patents, by an effective sui generis system, or by a combination of both. The TRIPS Agreement does not explicitly require countries to join UPOV, but the UPOV Convention was widely recognised as a ready-made sui generis system that could satisfy this obligation. As a result, many developing countries across Asia, Africa, and Latin America joined UPOV or aligned their national laws with UPOV principles in the years following TRIPS. Bilateral and regional trade agreements – particularly with the EU, USA, Japan, and EFTA – further pressured developing nations to join UPOV 1991, often as a condition of market access. Today, UPOV has members covering 99 states, a dramatic expansion from its original six founding nations.

India’s position: a distinct path 🔗

India’s response to TRIPS obligations illustrates how countries can chart their own course within the international IP framework. India was required, as part of its TRIPS obligations, to either adopt the UPOV model or develop its own sui generis law. It chose the latter, enacting the Protection of Plant Varieties and Farmers’ Rights (PPV&FR) Act, 2001. The reason was clear: the UPOV Convention makes no mention of farmers’ rights, and India – where agriculture involves hundreds of millions of small farmers who depend on saving and exchanging seeds – could not adopt a system that ignored their interests entirely.

India’s PPV&FR Act explicitly recognises farmers not just as cultivators but as conservers and breeders in their own right. It allows registration of farmers’ varieties and landraces, preserves farmers’ rights to save, use, exchange, and sell farm produce including seeds of protected varieties (though not under a brand name), and includes benefit-sharing provisions for farming communities. India remains an observer, not a full member, of UPOV – a deliberate choice reflecting its commitment to balancing innovation incentives with the agricultural realities of a developing economy. The UPOV Council has rejected India’s law as not meeting UPOV’s requirements, which itself underscores the fundamental tension between the UPOV model and the needs of developing countries.

Why UPOV matters for understanding IP law 🔗

UPOV represents a foundational example of how intellectual property rights have been extended beyond traditional domains like inventions, literary works, and trademarks into living biological material. It demonstrates both the power and the limits of using IP mechanisms to incentivise private investment in areas of public importance – in this case, agricultural innovation and food security. The recurring debate around UPOV – between stronger breeders’ rights and preserved farmers’ privileges, between standardised international norms and nationally tailored solutions – reflects tensions that run through the entire field of international IP law.

For law students, UPOV is also a practical lesson in how international conventions evolve: through periodic revision in response to economic pressures, technological changes, and the shifting balance of power between developed and developing nations. Each successive Act of the UPOV Convention strengthened commercial breeders’ rights, and each revision generated corresponding debate about who the system truly serves.

What do you think? Given that TRIPS gives countries the flexibility to design their own plant variety protection systems, why do you think so many developing countries still face pressure to adopt the UPOV 1991 model specifically? And considering India’s distinct approach through the PPV&FR Act, do you think a country can effectively balance the commercial interests of plant breeders with the traditional rights of farmers within a single legal framework?
