The genetics that contain the RR1 trait won't expire. Those genetics are IP. The courts have established that. So, unless somebody has access to some very old and poorer performing genetics, the farmer will still not be able to legally save his seed. In reality, there are very few genetics that have the RR1 trait in them. Sure, some companies will likely split from Monsanto and start their own breeding programs with the RR1 trait, but those farmers will still not be able to legally save the seed, and it won't be Monsanto's fault.
