>who finds their legal pursuit of farmers who have (frequently accidentally) had their crops cross pollinate with Monsanto patented breeds
This is mostly a myth. All of the lawsuits have been about people who have intentionally used Monsanto breeds (mostly just one court case about one farmer in particular). The rest of their lawsuits, which are a relatively small number, have been against people who broke their contracts with Monsanto, not people who have experienced accidental cross pollination. There are no cases of Monsanto going after farmers for inadvertent contamination and the company has even explicitly stated that it will not sue farmers for it.
