Your source is very biased. Do you have any evidence of Monsanto suing farmers for unintentionally growing crops from seeds that have drifted onto their fields?

The most well know case is Monsanto Canada Inc v Schmeiser, but the facts do not support the farmer's claims of innocence. It's clear he tried to grow and acquire as many of Monsanto's seeds as he could.

The case you pointed to is about invalidating Monsanto's patents, or at least rendering them unenforceable. It's plainly just an attempt for farmers to save money by using Monsanto's seeds without paying for them and nothing about "victimisation".
