Mr. Chair, I'd be happy to take that.
The UPOV level provides a framework for minimum requirements and consistency at the international level, but it doesn't preclude sovereign states that are party to it from putting in additional measures or tweaking it to meet their needs.
On the question of heirloom or heritage varieties, I think we need to be really clear about that. When we talk about the UPOV system and plant breeders' rights, it's focal point of concern is new varieties, and in fact heritage or heirloom varieties by the very nature of their being in the public domain for a prolonged period of time would never qualify for protection as being new. There is no concern here about developers taking heritage or heirloom varieties and covering them in the scope of a PBR.
Quite the opposite, an interesting thing that happens is quite often a rights-holder will surrender their rights much earlier than the 18 years of protection—we're moving to 20 with the proposed amendments—quite often much earlier, and if it's an innovative or successful variety it falls into the public domain and becomes the heirloom or heritage variety of tomorrow. There's this idea of continuous improvement. Farmers will continue to be protected. They will continue to have choice in what they source in terms of varieties, either PBR or non-PBR protected. It's really entirely up to them.
