First of all, we certainly use patents less for protecting our intellectual property, but I have to say, as I said in my comments, that to a certain extent that's because of the cost and expense of the process we're required to go through. We place significant importance, as a result of that, in the prior art of all the documentation and copyright that would surround an invention, and we use that as our primary step in terms of protecting the intellectual property.
That said, though, we have been going through a patent program in the last couple of years where we're trying to file more patents, particularly in Canada. We have a number of people in R and D in the Waterloo region, and in order to encourage innovation within the company, we are encouraging the filing of more patents, and you've seen in the last couple of years now that we're starting to file 10 to 12 patents a year, whereas in the past we were primarily focused on the copyright, as you indicated, as well as prior art.
