Key facts
- The U.S. is among a small number of countries that permit patents on plant varieties.
- Dominant seed companies use patents to restrict competition and research.
- A May 2026 Department of Justice court filing highlighted that seed patents are hindering agricultural competition and research.
- Farm subsidies are observed to correlate with increased seed prices, with companies raising costs based on farmer affordability.
- Independent researchers face threats of patent-infringement lawsuits, deterring them from studying crucial crops.
The United States, one of the few nations allowing patents on plant varieties, faces criticism that these patents stifle innovation and redirect farmer subsidies into corporate profits. A May 2026 Department of Justice court filing indicated that seed patents are obstructing competition and research within the agriculture industry.
Historically, farmers freely saved and exchanged seeds, fostering crop diversity. However, the advent of patents on living organisms in the 20th century allowed companies to patent engineered traits and restrict farmers from saving their own seeds. This has led to a significant increase in seed prices, with genetically engineered seeds costing 463% more since 1990, while farmer crop prices rose only 56% in the same period.
Furthermore, studies suggest that seed companies adjust their prices upward in response to farm subsidies. For every 1% increase in subsidies, seed prices rise by 0.5%. This dynamic, coupled with consolidation limiting farmer options, results in farmers being price takers rather than price makers, with public money intended for farmers benefiting seed suppliers and commodity purchasers.
Dominant seed companies also use patents and restrictive contracts to prevent competitors and independent researchers from developing new breeding programs or studying patented seeds. This lack of transparency and research poses risks, as the vulnerability of crucial crops to pests and pathogens remains unknown outside these large corporations.
