Intellectual Property Rights (IPR) on Seed
Type of IP Protection
Plant Variety Protection (PVP)
Is it legally binding?
Yes – Plant Patent Act, 1930
Yes – Plant Variety Protection Act, 1970
Yes – Patent Act, 1952
While patent law dates back to 1790, this law provides the basis of the most modern patent law applied
What and whom
does it cover?
Plant patents govern asexually reproducing plants only. Plant patent apply to all users regardless of how they obtain the material.1
USDA’s Plant Variety Protection Office provides PVP certificates to developers who prove that a new variety is new, unique, uniform, and stable. PVP apply to all users regardless of how they obtain the material.1
Utility patents are available through the U.S. Patent and Trademark Office for inventions that are novel, non-obvious, and useful. They have been awarded for finished varieties, plant parts, genetic traits, and more. Utility patents apply to all users regardless of how they obtain the material.1
does it last?
20 years, with opportunity for renewal
20 years, then enters public domain
Is seed saving
No exemption for propagation
Provides exemption for farmers to save seed for on-farm use only
Typically enforced to exclude seed saving and production without a license
Depends on the license with the trademark holder
Permission must be granted
Depends on the contract, but most licensing agreements used by the seed industry restrict seed saving, especially among their farming customers.
Is breeding and research allowed?
No exemption for breeding/research
for breeding and
Typically enforced to exclude breeding and research without a license
Yes, unless the trademark is combined with more restrictive IPR, like a patent.
Typically must have permission to market
a trade secret
Depends on the contract. Those between universities (e.g., material transfer agreement) are typically used to support research, while those used by industry typically restrict research.
Yes, and the pledge also applies to future progeny developed from an open-source parent.
Can I market
Must have permission from patent holder
to propagate, often
for a royalty and
Provides exclusive marketing rights to the PVP certificate holder. Growers cannot sell saved seed
Typically enforced to exclude the sales of propagated seed without a license
Must have a license or permission to use trademark as a marketing right
Typically must have permission to market a trade secret
Depends on the contract/license
does it cost?
$4,000 – 8,000+
(when patent attorneys are involved)
(fees are subject to change)
$5,000 – 10,000+
(when patent attorneys are involved)
$200 – 600
(monitoring and protecting a trademark’s use is costly)
Typically a fee or royalty is paid for licensing or selling someone else’s variety
Yes – Registered trademarks are protected under both federal and state law
Yes – While trade secrets are not protected by federal law in the U.S., they are protected by state law in most states. Trade secrets are also considered a part of international law per TRIPS, or Trade-Related Aspects of Intellectual Property Rights.
Yes – Contract law is the body of law governing agreements that can be upheld in court
Maybe – Some legal opinions suggest that the pledge is enforceable, much
like a "bag tag."
A trademark is a brand name. For plant developers, it’s possible to trademark a name associated with a variety.2 The trademark means that no one else can use that name but makes no direct claims on the variety itself. It is usually, though not always, associated with one of the others forms of IP.
Sometimes referred to as “confidential business information,”
a trade secret is protected or exclusively held information, typically by industry.3
Contracts are used widely in the seed trade between seed developers, between farmers and developers, and more.4
Contracts are binding between the signatories, but the materials are usually associated with one of the others forms of IP.
OSSI pledges cover varieties that aren't protected by another form of IPR. Plant breeders must submit
an application to the
OSSI Variety Review Committee to earn approval for using the OSSI seal and pledge.5
10 years, with 10-year renewal terms (must prove ongoing use)
No end, as long as secrecy is maintained
No end, unless stipulated in the contract
1 For example, if a friend gives you a cutting of a plant patented apple, the legal requirements of the plant patent apply to you.
2 For example, Kamut is a trademark name for a specific variety of Khorasan wheat. To differentiate Kamut products from other Khorasan wheat products, Kamut growers must use this particular variety, be certified organic, and the end product must also meet certain criteria, such as protein content. Khorasan wheat can still freely be grown by anyone, but to use the trademark Kamut, these and other stipulations apply as a way to control the quality of the product, and thus the brand.
3 As an example in plants, trade secrets often govern inbred lines used to make an F1 hybrid. While there may be no additional protection on the actual F1 hybrid itself, the inbred lines and combinations of lines used to make an F1 hybrid are protected by companies as trade secrets. While you can save seed from an F1 hybrid, the progeny will not grow true to type, and it is also very unlikely that you would ever be able to re-create the inbred parent lines.
4 Contracts include material transfer agreements that outline allowable practices for specific germplasm, and are often used between plant developers both in the public and private sector. Contracts also come in the form of licensing agreements on seed bags and packets, serving as a binding agreement between any user of that seed (farmers and researchers) and the proprietary owner. Simply opening a bag or packet of seed with a licensing agreement associated with it, known as “bag tags,” binds you to the terms in the agreement. These terms often restrict seed saving and selling, and restrict use for research, including for breeding and variety trial purposes. This practice is not too different from opening or downloading software that includes a shrink-wrapped agreement. Contract law can serve as a highly restrictive form of IPR because, unless stipulated, contracts don’t end. They are especially obstructive to farmer and breeders’ rights when combined with additional layers of IPR, such as a utility patents. Fortunately, contracts can also be written in a way that adheres to the principles of fairness and shared benefit, supporting one’s freedom to operate by not restricting seed saving or research of any kind, including breeding. Contracts often stipulate that a royalty be returned back to the breeding program and/or farmer collaborators.
5 The OSSI pledge states: "You have the freedom to use these Open Source Seed Initiative – Pledged seeds in any way you choose. In return, you pledge not to restrict others' use of these seeds or include this Pledg with any transfer of these seeds or their derivatives."
