The Agrochemical Cartel · Investigation · 1930–2018
How seed went from public property to patented product.
For millennia seed was a commons farmers saved and shared. Across the 20th century, three laws and two Supreme Court rulings turned living plants into private, patented property.
FACT
§2 · Thesis
Seed used to belong to everyone. Four legal steps enclosed it into private, patented property — and a few firms now own most of the proprietary market.
The legal history and the consolidation are FACT. The one number we hold back is the oversold '95% of all seed owned.'
§5 · Graded Claim
Diamond v. Chakrabarty (1980): the Supreme Court holds that living, human-made organisms can be patented.
FACT
The Court held 5-4 that a live, engineered micro-organism is patentable — the distinction being nature's handiwork versus human invention, not living versus inanimate. It opened the door to patenting living things, soon extended to genetically engineered plants and seed.
§5 · Graded Claim
Bowman v. Monsanto (2013): a unanimous Court rules farmers cannot save and replant patented seed.
FACT
Patent exhaustion does not permit a farmer to make new copies of a patented seed by planting and harvesting it without permission. The ruling cemented, at the highest level, that saving patented seed is infringement — reversing millennia of practice for the crops that matter most.
The record
The four steps of enclosure.
- Plant Patent Act (1930): first patents on asexually propagated plants — the first crack in the commons.
- Plant Variety Protection Act (1970): protection extended to seed crops, but KEPT a farmer seed-saving exemption.
- Chakrabarty (1980): living organisms are patentable subject matter.
The record
- Bowman (2013): patent exhaustion doesn't let farmers save patented seed — the exemption erased for GE lines.
§5 · Graded Claim
Six firms became four — and the biggest is an IG Farben descendant.
FACT
The 2017-2018 mega-mergers condensed the sector into Bayer (bought Monsanto), Corteva (Dow-DuPont), Syngenta (China's state-owned ChemChina), and BASF, controlling the majority of the global proprietary seed/trait market. Bayer itself descends directly from the IG Farben chemical cartel — the thread this hub follows into the companies' crimes.
§5 · Graded Claim
The honest number: not '95% of all seed' — but >90% of US corn/soy/cotton acreage.
SOME SMOKE
'A handful own 95% of seeds' overstates it as a blanket and we don't make it — farmers still grow unpatented and public-domain varieties. The defensible, sharper claim: the top four control the MAJORITY of the proprietary seed/trait market, and for major US commodity crops >90% of planted acreage uses GE seed from a few firms. We cite the crop-specific reality, not the round number.
§7 · Why it matters now
Why it matters.
Seed is the first link in the food chain, and for most of history it belonged to everyone. This enclosure handed that link to a few corporations and bound it to their patented chemicals — a bundle the hub traces from the pesticide immunity playbook to the antitrust cases and the companies' own criminal records. The law didn't have to go this way: the 1930 Act carved a narrow exception and the 1970 Act kept a farmer's right to save seed. Step by step, the exception became the rule.
