It is not often that one’s vocation and avocation meet. But when they do, the intersection can be illuminating and instructive. I’ve spent all of my professional life working in the world of intellectual property—patents, trademarks, and the systems built to protect innovation. I generally find this a noble and rewarding profession. My personal life has been deeply rooted in nature, horticulture and cultivation. I have a love of seeds and plants that have been passed down for generations.

There is a unique collision between these two worlds: the legal frameworks which protect ideas; and the living, evolving nature of seeds themselves. This post was conceived from that interesting collision. I wanted to share how intellectual property is reshaping something as ancient and fundamental as seed. And explore the profound consequences for farmers, gardeners, biodiversity, and our collective future.
Seeds are the foundation of agriculture, biodiversity, and food security. For millennia, farmers and growers have saved, shared, and improved seeds to adapt crops to local conditions and changing climates. Today, however, seeds have become a battleground of intellectual property (IP) rights. This includes corporate consolidation, and an often-controversial shift in who controls the world’s food supply. In this article we’ll walk through how and why seeds are patented and trademarked, how these practices affect farmers and biodiversity, why a few corporations now dominate seed markets, and how these trends may undermine nature’s ability to adapt to a rapidly changing world.

How and Why Seeds Are Patented
Historically, plant varieties were considered part of the public domain. Anyone could save and replant any seeds year after year. In fact, the US Patent and Trademark Office was a primary entity (along with the USDA) which distributed free seeds to farmers for almost 100 years. That changed with key legal reforms in the United States. These reforms extended robust intellectual property protections to seeds and plant genetics.
The first Plant Patent Act was signed into law in 1930. It covered asexually reproduced plants: cuttings and graftings (clones). It was used primarily for ornamentals such as roses and fruit trees. This protection was enacted to encourage innovation to increase the variety of plants, at a time when many new (hybrid) fruit trees (including the Burbank potato and the Santa Rosa Plum) were being bred by notable and noble horticulturists such as Luther Burbank. Hybrid plants like these new varieties are cloned because their seeds produce unpredictable offspring. So the first patent law that was enacted only applies to cloned plants; coverage does not extend to seeds.
In 1970, Congress created the Plant Variety Protection Act (PVPA). The PVPA grants limited exclusivity to plant and seed breeders narrowly for new varieties of sexually reproducing plants via seeds or tubers. PVPA still allowed farmers to save seeds and continue breeding new varieties. However, later legal developments broadened protections significantly.
Changes to Intellectual Property Laws
In the decades that followed, a series of court decisions and law changes allowed corporations to patent not only new varieties, but also to obtain patents for breeding methods, genetically modified traits, germplasm, which carries a seed’s genetic material, and even the plant itself, including its leaves, flowers, and seeds. These rulings effectively transformed seeds from a renewable resource growers could collect from their own plants into a product farmers have to buy every year. In 2001, the U.S. Supreme Court decision in J.E.M. Ag Supply v. Pioneer Hi-Bred International upheld the patentability of sexually reproduced plants and seeds under utility patents. Meaning, companies can now claim proprietary rights to virtually any new seed variety or genetic trait, whether it was naturally occurring or lab modified. USDA–Economic Research Service
Utility patents differ from PVPA certificates because they do not include exemptions that allow farmers to save seeds. Nor are there exemptions for other breeders to use protected genetics for research. (This includes research to test for safety of the genetic material. Labs are unable to study if genetically modified seeds are safe because companies claim their seeds are protected by trade secret.) Consequently, farmers planting patented seeds must agree not to save or replant them. In the 2013 Supreme Court case Bowman v. Monsanto Co., the Court confirmed that even if a farmer legally purchased patented seed, saving and replanting seed from the crop still infringes the patent holder’s rights.
Expanded Eligibility under consideration
In 2025, legislators introduced the Patent Eligibility Restoration Act, (or PERA) to clarify and expand the eligibility for protection for different types of patents. It includes the clarification that plants (and other natural material, including genes) that are unmodified from how they exist in nature would be definitively excluded. However PERA expands eligibility for any plant that is in any way “isolated, purified, enriched, or otherwise altered by human activity” or “employed in a useful invention or discovery”. As of January 2026, PERA has not yet been enacted into law. However some patent attorneys are rushing to draft patents now, with the intent that by the time the application gets to the examiner, these guidelines will be enacted.
The Explosion of Intellectual Property Filings for Seeds
Save
This change in law transformed seeds from a renewable agricultural resource into proprietary products governed by strict intellectual property rules. And since that time, there has been an explosion of plant patents and PVPs granted in the US alone. In other words, farmers saving U.S. patent-protected seed can face patent infringement lawsuits from the patent holder. Damages can include lost royalties, treble damages, injunctive relief, and attorney fees. To further confuse the issue, companies do not always clearly label seed packages which are patent protected.
Impact on Farmers: Seed Saving and Legal Restrictions
One of agriculture’s oldest traditions—saving seed from one harvest to plant the next—is now restricted in many jurisdictions because of patent laws. Under the World Trade Organization’s TRIPS Agreement, planting, harvesting, saving, and exchanging seeds of patented varieties in any member country can constitute use that violates Intellectual property rights. In practice, this means farmers who wish to use new ‘high-performance’ seeds must repurchase them each year, often at high cost. And, they may face legal consequences for replanting patented seed without authorization.
This shift has clear financial implications. Patented seeds that demand annual purchase rather than reuse create ongoing expenditures for farmers they previously did not have. Patent holders also frequently couple seed sales with licensing agreements that require farmers to buy related chemicals. Because the companies holding the patents are chemical companies, seeds get bundled with herbicides or proprietary treatments. This effectively locks growers into a “technology package” controlled by that same corporate entity. Farm Action
And this does not just affect large-scale farms, either. A line of introduced GMO tomato seeds including the now infamous “Purple” are just the latest examples of patent-protected seed being sold to home gardeners. “Purple” is unique in that it gets its purple color from genes inserted from a purple snapdragon, not another edible vegetable. In its first years it has been the subject of much controversy, including a price tag of $2 per individual seed, and several patent disputes, both in the US and Europe.

Trademarking and Naming Rights in Seeds
In addition to patents, trademarks also play a role in how agricultural products are marketed. Unlike patents, a trademark protects a brand name, logo, or symbol—not the genetic material itself. Trademarks influence how plant varieties are named, commercialized, and perceived in the marketplace. The brand names (such as ‘Round-Up-Ready Soybeans’), logo, or product line under which seeds are sold can be protected, shaping both recognition and revenue.
You may have noticed that many plants have multiple names. First, they always have a horticultural name (for example, Centaurea cyanus). Second, many have a common use name – our Centaurea cyanus goes by the common name ‘cornflower’ or ‘bachelor’s buttons’. And then, we often have a commercial, or brand name, such as ‘Florist Blueboy’, which is an actual example of a trademark of a common cornflower.
How trademarks are used in the plant world
Plant breeders often leverage a trademark name for marketing purposes, to promote plants which already had valid cultivar names. Trademark names are distinctive, catchier, and more memorable. The goal is to convince the public that the company’s marketing name is actually the name of the plant, and to therefore sell those plants at higher prices.
In the world of apples, you may notice that old favorites such as ‘Granny Smith’ and ‘Fuji’ are becoming difficult to find in mainstream supermarkets. This is because apple breeders and growers have moved away from the common varieties in favor of trademarked apples. Those trad apples like Granny Smith and Fuji are in the public domain. Meaning anyone can grow and sell them without special licensing. Creating a new apple isn’t quick or cheap. Trademarking the name helps protect that investment. Breeders gain control over pricing and the orchards that are licensed to grow their apples. Those newer varieties are protected, pricier, and their catchy names lure us into buying them.
PGIs and PDOs Protecting Special Regional Plants
Protected geographical indications (PGIs) and Protected Designation of Origin (PDO), types of trademarks in the US and elsewhere, impose further restrictions on plants and agricultural products. These agricultural intellectual property protections are tied to place and production methods. They limit the use of certain plant names—such as Champagne, Kalamata Olives (and other olive and oil types), wine grapes and many other fruit and tomato varieties. No grower can technically sell a Kalamata olive product as a Kalamata olive, even if it is genetically the exact same plant, unless it is grown in the Kalamata region of Greece. Similarly, chianti wine is only sold as chianti if it hails from a specific region in Italy, even if the exact same sangiovese grapes are used and the production method is the same.
The most famous example of a protected tomato is the San Marzano. Technically, if you grow a San Marzano from either seeds or a start in your home garden, you aren’t actually allowed to call it a San Marzano tomato. Especially if you have any intention to market or sell your tomatoes. Unless, of course, you live in San Marzano at the base of Mount Vesuvius in Italy.
PGIs and PDOs do not prevent the cultivation of the underlying plants elsewhere. But they tightly control how growers and farmers can label and sell those plants and their products. In this way, trademarks and geographical indications add another layer of commercial and cultural value – and restrictions – to seeds and plants.
Industry Consolidation and the Disappearance of Seed Diversity
The emergence of strong intellectual property protections coincided with profound consolidation in the seeds industry. What was once a diverse marketplace of thousands of independent breeders has narrowed substantially. According to a USDA study from 2023, consolidation and restrictive IP regimes have concentrated the majority of seed genetics and traits into the hands of a few billion-dollar corporations. These companies use patents and licensing agreements to maintain control over both seeds and their traits. Food & Power
Today, just a handful of multinational firms dominate global seed markets. For major commodity crops such as corn, soy, and canola, four corporations control the vast majority of seeds and intellectual property rights. This consolidation reduces competition, elevates seed prices, and leads to a significant narrowing of the seed varieties available to farmers. Food & Power
Author Mark Schapiro captures the essence of this shift:
“While few were looking, seeds became one of the hottest properties in the corporate market. American and European seed companies have been buccaneering their way through the world’s seeds, picking and choosing the ones to patent and put into mass production. This means they have retained exclusive rights to resources that have been in the public domain for millennia.”
The Consequences for Biodiversity and Climate Resilience
The narrowing of seed options has a direct impact on biodiversity. A diverse gene pool is vital for crops to adapt to local climatic conditions, resist pests and diseases, and respond to environmental changes. Remember the story of the 1840s Irish Potato Famine where an estimated million people died due to crop failure? How about the Gros Michel banana extinction in the 1960s? Both were due to monoculture practices. Effectively all of the crop were a single plant species which was vulnerable and infected by disease. The disease wiped out the crop.
These devastating crop losses might have been avoided had multiple varieties with various natural resistance been planted. This same problem happened again in 1970 when most of the corn crops throughout the US Midwest were wiped out. This time it was southern leaf blight affecting a monoculture across the US resulting in a billion dollars in crop losses.
This is not merely a historical issue. Syria’s 2025/2026 wheat, cotton, barley and olive crops are all in a serious state of failure. A reliance on water-intensive monoculture strains during an extended drought was one of the factors that decimated agricultural production in Syria.
Seed Adaptation
A wide genetic pool acts as a safeguard against the risks of monoculture. Conversely, reliance on a narrow set of varieties leaves crops more vulnerable to disease outbreaks and climate change. Seed patenting tends to favor commercially profitable traits. They are selected (and engineered) for traits such as herbicide tolerance and disease resistance. This engineering is often at the expense of lesser-known or heirloom varieties that may naturally carry adaptations to specific environments. Sustainability Directory
This trend has significant implications for climate resilience. As the global climate becomes more variable, locally adapted seed varieties—developed through generations of small-scale seed saving and breeding—are increasingly valuable. These seeds, when saved generation after generation, carry a natural tolerance and adaptations (epigenetics) to the evolving climate conditions. However, the dominance of uniform, patent-protected seeds developed in lab conditions without the ability to evolve and adapt restricts the evolutionary potential of crops to naturally adapt to local conditions and rising uncertainty.
Corporate Strategies and the Rise of Hybrid Seeds
Large agribusiness corporations have combined seed genetics with their own chemical products to create integrated systems. These engineered seeds and related chemicals promise higher yields… under specific and controlled conditions. So-called “technology packages” link genetically modified seed traits with specific herbicides and pesticides. Setting aside the fact that farmers are dousing genetically modified food crops with these chemicals, these packages pose other problems. This effectively encourages farmers to adopt an entire corporate ecosystem rather than individual components. Critics argue that this approach undermines farmers’ autonomy and drives dependence on annual repurchases of both seeds and chemicals. Farm Action
Integration like this is a modern iteration of controlling agriculture through IP and market power. These engineered seeds may offer advantages in uniformity and performance. But the long-term effects include decreased genetic diversity, decreased ability to adapt to changing environment conditions, and reduced flexibility for growers to experiment with and/or adapt seed lines to their unique regional conditions.
Responses and Alternatives: Seed Savers and Open Source Initiatives
In response to the increasing control of seeds by large corporations, alternative movements have emerged. The Open Source Seed Initiative (OSSI) is one such effort, seeking to preserve seed freedom. Their mission is to make new crop varieties available under an open-source pledge. The open source pledge allows farmers to use, save, share, and breed seeds without intellectual property restrictions.
There are other seed-saving organizations, such as Seed Savers Exchange and the Organic Seed Alliance. Both of these organizations advocate for preserving heirloom varieties and maintaining a shared genetic pool. These efforts aim to protect agricultural biodiversity and democratic access to plant genetics, countering the trend toward privatization.
Save
If you are a home gardener or small backyard farmer, chances are good you are buying seeds in small packages, and getting them from independent companies. But it is always good to know what to look for, especially when buying seed in quantity. And also because patent protected seed for backyard gardeners is definitively on the rise.
Open-Pollinated (OP): Seeds that grow true-to-type, meaning you can save seeds and get the same plant next year.
Heirloom: Varieties passed down through generations, known for unique flavors and history.
Safe Seed Pledge: Many reputable companies sign this pledge, committing not to create, buy, sell, or trade GMO seeds.

Conclusion: Balancing Innovation, Farmer Rights, and Biodiversity
The intersection of seeds and intellectual property reveals a complex interplay between innovation incentives and long-held agricultural practices. Patents and trademarks have enabled significant and beneficial advancements in plant and seed technology and marketing. Yet they also restrict traditional practices like seed saving, concentrate market power in a few multinational firms, and have accidentally contributed to an unsustainable rise of monocultures.
Farmers—especially small-scale and developing-world growers—face challenges. Their ability to save and reuse seeds is constrained by legal and contractual obligations. At the same time, biodiversity faces pressure as commercial varieties displace locally adapted seeds that would otherwise support climate resilience.
In navigating this landscape, it’s essential to recognize both the benefits and the trade-offs of intellectual property rights on seeds. But it is equally important to consider how policies, open-source frameworks, and community efforts can help sustain a diverse, resilient agricultural future.
