2014 marked the expiration of Monsanto’s patent on the first generation Round-up Ready technology. But, this expiration does not mean that farmers using seed from first generation Roundup Ready technology will be able to save harvested seed for planting a subsequent crop. Many seed companies utilizing this technology may consider other federal law protections afforded them. One such protection would be the Plant Variety Protection Act (PVPA). Another protection would be the use of contracts.   A company also may look at utilizing patent law to limit seed saving. You will need to consider each one of these to determine if saving the seed is allowed.
