Yes, certainly the area of patents is definitely the next step after copyright. Copyright was very important for a number of industries. A lot of people don't realize that software is protected by copyright too, but patents are absolutely essential. I think people are starting to realize this with the recent sale of Nortel's patents for $4.5 billion and the purchase of Motorola Mobility's patent portfolio for $12.5 billion.
A lot of countries and areas are using patent protection as non-tariff trade barriers, to be quite frank, and you're seeing a lot of this in the smart phone industry, which, despite its pervasiveness in North America, is really an industry in its infancy. You're seeing a lot of these court battles in international places where competitors try to shut each other out of different markets, based solely on patent protection. So it's definitely the next frontier, so to speak, in terms of international trade.
