While the USDA has not established an upper limit on the amount of trace contamination that is permissible, the appellants argue, and Monsanto does not contest, that ‘trace amounts’ must mean approximately one percent (the level permitted under various seed and product certification standards). We conclude that Monsanto has disclaimed any intent to sue inadvertent users or sellers of seeds that are inadvertently contaminated with up to one percent of seeds carrying Monsanto’s patented traits.
For purposes of this appeal, we will assume (without deciding) that using or selling windblown seeds would infringe any patents covering those seeds, regardless of whether the alleged infringer intended to benefit from the patented technologies. [emphasis added]
The estoppel protects EVERY farmer in the United States – not just those in our Plaintiff group.
