I'll start the response, and then I can turn to my colleague on the policy issues.
With regard to patent trolls, we've been looking at this very closely over the last few years. What we have determined from an IP office perspective is that the more challenging issues are largely focused in technology areas such as software, and that seems to be concentrated more in the United States. We patent software differently here in Canada, and we are not noticing the same kind of trolling activity here. In fact, it's very limited.
That said, as I mentioned, most Canadians will be filing in the United States. Anything we can do to help inform them of the market, whether it's the U.S. or other markets, that is our job, to bring that to light.
