It would be very tough to know. Nortel is an easy example. You can say that there were thousands of patents and they had a huge value to other companies, but sometimes the most valuable patents are the ones where you haven't quite figured out what you have yet, and I don't know how the government would get involved in reviewing that.
There's probably a place where there can be a line drawn as to where the significance of the assets becomes so great that you say it should be looked at, but it's very difficult to know, because sometimes you find out ten years later; you dust off that patent and finally realize what you have. It's a challenge to know how.... You can't be involved in reviewing every deal that involves intellectual property, because those are assets that companies cross-license and sell back and forth fairly freely.
