This is a tease-out of a broader study that they did for the United States primarily, and Canada fit into it. If you would, please look at that.
It brings me to a second question about metrics. You've been able to tease out some numbers on Canadian universities filing in Canada. If I understand correctly, you don't have that kind of information on filing in the United States, or can you go piece by piece to pull it out, although there's no repository for it?
