I'd like to add that patent thickets happen principally in the States and in the U.K. where they allow patenting of software, where things tend to move quite fast and it's very important to secure your position in the market, and they do that a lot through IP.
We don't see a lot of thicket evidence here in Canada because of the laws that we have. But because of the foreign nature—as I've explained before—of our businesses, a lot file in the U.S. where there are thickets. So although it's not happening in Canada, it's still quite a concern to businesses in Canada that file outside of the country.
