The large enterprises, especially in the IT field, are very sophisticated, and they'll have a licence. It's almost impossible to put a product on the market without violating somebody's patent. So you come up with arrangements about how you're going to do it.
It's really the smaller enterprises that exist mostly in the United States, the so-called trolls, that take advantage of the U.S. jury system to win exceedingly high damage awards that are out of proportion. So as long as we resist those, we can at least lessen the threat of trolls in Canada.
There is very little IP patent litigation in general in Canada. Most of it happens in the United States, and then we follow. So it's hard to get an exact figure on what the cost is to Canada, because most of the litigation happens elsewhere, and we're just the tail.
