Whether patent exhaustion permitted Bowman to plant patented commodity soybeans and save the harvested progeny for later planting without Monsanto's permission.
Holding
No. Patent exhaustion allowed Bowman to use, consume, or resell the particular soybeans he bought, but it did not give him the right to make new patented soybeans by planting and harvesting them.
Reasoning
Patent exhaustion provides that an authorized sale terminates the patentee's rights in the particular item sold. Once Monsanto, or an authorized seller, sold a soybean, its patent could not prevent a later owner from reselling that bean, consuming it, or feeding it to animals. But exhaustion does not transfer the separate right to make the patented invention; that right remains with the patent holder.
Planting seed to harvest a new crop creates new articles embodying the patented invention. Bowman did not simply use or resell the commodity beans he purchased. He planted them, cultivated the resulting plants, applied glyphosate to select for the patented trait, and harvested many more glyphosate-resistant soybeans. That process was the making of new patented seed, even though the original seed supplied the biological mechanism of reproduction.
A contrary rule would make patent protection for self-replicating seed practically worthless after the first authorized sale. Farmers or competing sellers could buy seed once and reproduce it indefinitely, while Monsanto would receive compensation only for the original articles sold. Limiting exhaustion to the particular sold article preserves the patent's incentive to innovate and prevents copying from eliminating the patentee's exclusive right to make the invention.
The Court's earlier decision in J.E.M. Ag Supply reinforced this conclusion. J.E.M. recognized that utility patents provide stronger protection for seeds than Plant Variety Protection Act certificates, including the ability to prohibit a purchaser from saving harvested seed for replanting. Treating exhaustion as authorizing Bowman to save and replant patented progeny would contradict that distinction.
