What I would say is that the more buttoned-down it is, and the clearer we can see that they have a freedom to operate and a market that they can attack, the more likely it is we are going to fund them, number one, and the more likely it is we'll be able to fund them in a greater amount and attract more capital from the private sector.
If you have a fairly small market that you can address, that's not interesting to us. We're motivated to deliver the benefits to Canadians in terms of the environmental benefits and the economic benefits. So the bigger the bang for the government's buck we can get, the more interested we are. If it's a very niche market where there are a lot of competitors that have potential patents out there that they may bump into, that makes it less interesting for us.
In terms of what we can do inside the project, that really is a function of the other members of the consortium and a variety of other factors, rather than specifically the status of their patents.
