Well, when you combine all the different elements, Canada has one of the strongest systems of patent protection in the world, particularly for pharmaceuticals.
As I mentioned in my remarks, one important difference is that Canada alone of the G-7 countries does not have a patent term extension system. Patent term extension refers to the desire of patent holders to add the time that it takes for regulators such as Health Canada to approve a drug, on the basis that it's safe and effective, to the 20-year term patent protection. Canada does not have that. But we have other elements that are combined, such as patent linkage and data exclusivity, and which protect drugs at a very high level. So if you put those in combination, I would argue, and I think most experts would agree, that we have one of the highest forms of patent protection for drugs in the world.
