 Monsanto has filed patent infringement suits against 145 farmers, but proceeded to trial with only 11.In some of the latter, the defendants claimed unintentional contamination by gene flow, but Monsanto won every case.Monsanto Canada's Director of Public Affairs stated, "It is not, nor has it ever been Monsanto Canada's policy to enforce its patent on Roundup Ready crops when they are present on a farmer's field by accident ... Only when there has been a knowing and deliberate violation of its patent rights will Monsanto act."
