“It sells the seeds subject to a licensing agreement that permits farmers to plant the purchased seed in one, and only one, growing season. Growers may consume or sell the resulting crops, but may not save any of the harvested soy-beans for replanting. Petitioner Bowman purchased Roundup Ready soybean seed for his first crop of each growing season from a company associated with Monsanto and followed the terms of the licensing agreement. But to reduce costs for his riskier late-season planting, Bowman purchased soybeans intended for consumption from a grain elevator; planted them; treated the plants with glyphosate, killing all plants without the Roundup Ready trait; harvested the resulting soybeans that contained that trait;and saved some of these harvest-ed seeds to use in his late-season planting the next season.”
