Plant Variety Protection Act (PVPA)

The Plant Variety Protection Act (PVPA), codified at 7 U.S.C. §§ 2321-2582, is the U.S. federal statute that lets a plant breeder obtain a certificate-based intellectual-property right — a PVP certificate — in a new, distinct, uniform, and stable plant variety. Enacted in 1970, it is administered by the Plant Variety Protection Office (PVPO), a unit of USDA’s Agricultural Marketing Service — not by the U.S. Patent and Trademark Office (USPTO), which administers the two patent-based routes to plant protection instead. For research administrators and university technology transfer offices working with agricultural or plant-science breeding programs, PVPA is a distinct IP track from patent law, with its own application process, its own statutory exemptions, and its own overlaps and gaps relative to plant patents and utility patents.

What a PVP certificate protects

A PVP certificate protects a specific plant variety as bred — a defined, reproducible set of genetic characteristics that make the variety new (not previously sold or offered for sale beyond statutory grace periods), distinct from other known varieties, and genetically uniform and stable from generation to generation. It does not protect an underlying gene, trait, breeding method, or genetic construct in the abstract; those are the domain of utility patents. Historically, PVPA covered only sexually reproduced varieties (grown from seed) and tuber-propagated varieties (e.g., potatoes). The Agricultural Improvement Act of 2018 (the 2018 Farm Bill) extended PVPA eligibility to asexually reproduced varieties as well — plants propagated by cuttings, grafting, budding, or tissue culture rather than from seed — which for the first time created direct overlap with the older plant-patent system for that category of plant.

PVP certificate vs. plant patent vs. utility patent

Three separate legal tracks can protect a plant, and they are administered by two different federal agencies with different rules:

• PVP certificate (USDA/PVPO, 7 U.S.C. Ch. 57): covers sexually reproduced, tuber-propagated, and (since 2018) asexually reproduced varieties. Subject to statutory exemptions unavailable under either patent route (see below). Application is examined by USDA plant examiners, typically without the cost of retained patent counsel that a utility filing usually requires.
• Plant patent (USPTO, 35 U.S.C. § 161): covers only asexually reproduced varieties (grafting, budding, cuttings, tissue culture) — never varieties grown from seed, and never tuber-propagated plants. No statutory farmer’s or research exemption comparable to PVPA’s.
• Utility patent (USPTO, 35 U.S.C. § 101): can cover plants, seeds, genes, traits, and breeding or transformation methods directly, confirmed as proper patentable subject matter by the U.S. Supreme Court in J.E.M. Ag Supply Co. v. Pioneer Hi-Bred International, Inc., 534 U.S. 124 (2001). Utility patents carry no farmer’s-seed-saving or research exemption, making them the strongest — and most expensive to obtain and defend — of the three tracks.

A single breeding program can, in principle, pursue more than one of these for the same variety where eligibility overlaps (most commonly PVP certificate plus utility patent), though each track has separate filing costs, examination standards, and exemption exposure that a technology transfer office should weigh before choosing.

Certificate term

A PVP certificate runs for 20 years from its date of issue for most varieties, and 25 years for varieties of trees and vines (including their rootstock). This is measured from the certificate’s issue date, not the application filing date — a distinction that matters when comparing PVPA timing to a utility patent’s 20-years-from-earliest-filing term.

Statutory exemptions: farmer’s exemption and research exemption

PVPA includes two exemptions from infringement that have no direct equivalent under either patent route, and that any tech transfer office licensing a PVP-protected variety needs to account for:

• Farmer’s exemption: a farmer who has legally obtained seed of a protected variety may save seed from their own harvest and replant it on their own operation the following season, without infringing the certificate. This exemption was not extended when the 2018 Farm Bill added asexually reproduced varieties to PVPA — it applies to the original sexually reproduced and tuber-propagated categories, not to the newer asexual category.
• Research exemption: PVPA permits use of a protected variety for plant breeding or other bona fide research, including using it as a source of germplasm to develop a new variety. This is narrower than it may sound — it protects using the variety as research material, not commercializing a variety substantially derived from it without the original breeder’s rights being implicated.

Why this matters for university and ag-research technology transfer

Public land-grant university breeding programs — wheat, soybean, turfgrass, ornamental horticulture, and similar conventional-breeding programs — have historically relied on PVP certificates rather than utility patents for released cultivars, in part because a PVP certificate is generally faster and less expensive to obtain than a utility patent, and in part because the invention (a specific bred variety) fits PVPA’s scope cleanly. A technology transfer office evaluating a new plant-breeding invention disclosure needs to determine, early, which of the three tracks actually fits: whether the variety is sexually reproduced, tuber-propagated, or asexually reproduced (which determines plant-patent eligibility and, since 2018, PVP eligibility for the asexual case); whether the innovation is really the whole variety or an underlying gene/trait/method (which points toward a utility patent instead, per J.E.M. Ag Supply); and whether the farmer’s exemption’s effect on downstream licensing revenue changes the commercialization strategy relative to a patent route that carries no such exemption. Because PVP certificates and utility patents administer through entirely separate federal agencies (USDA/PVPO vs. USPTO) with separate application systems, timelines, and fee schedules, this is also a practical filing-logistics decision, not only a legal-scope one.

Frequently asked questions

Is a PVP certificate the same thing as a patent?

No. A PVP certificate is a distinct certificate-based IP right issued by USDA’s Plant Variety Protection Office under PVPA, not a patent issued by USPTO. It functions similarly to a patent — giving the holder exclusive rights to control propagation and sale of the protected variety for a fixed term — but follows a different statute, a different administering agency, and different statutory exemptions (notably the farmer’s and research exemptions) than either a plant patent or a utility patent.

Can the same plant variety be protected by both a PVP certificate and a patent?

For asexually reproduced varieties, yes in principle since the 2018 Farm Bill made PVP certificates and plant patents both available for that category — though a breeder typically chooses one route per variety based on cost, exemption exposure, and scope. A utility patent covering an underlying gene or trait can also coexist with a PVP certificate covering the specific variety, since they protect different things.

Does the farmer’s exemption apply to every PVPA-protected variety?

No. It applies to the original sexually reproduced and tuber-propagated categories PVPA has covered since 1970. The 2018 Farm Bill amendment that added asexually reproduced varieties to PVPA did not extend the farmer’s exemption to that new category.
