I'm not sure that I follow the linkage in your question. On the issue around patents, I don't have the numbers at my fingertips, but I believe that on a per capita basis Canada produces as many patents as the U.S. does, so that sounds like a strange number, but I really am not familiar with it.
The play that we have is around commercializing that, because the patents in themselves don't produce revenues and don't feed back into the economy, so it's taking companies that have intellectual property that's of value and getting them to be sustainable businesses operating in the global market. We are seeing that happening. Our results show that the compound annual growth in revenues of the companies that are inside the SDTC portfolio versus those that are not in it is twice as fast as the global CAGR, or compound annual growth and revenues. We believe we are building competitive Canadian companies and that they're competitive globally.
On the patent bit, I'm afraid I'm not able to answer.
