Yes. My position is that the push for WTO-plus patent protection, particularly from the pharmaceutical industry, is basically a bottomless pit. They will never be satisfied unless governments—as I think your government is feeling now in the Canada-European negotiations—take a very, very firm position that 20 years of patent protection is more than sufficient. Also, there are legitimate issues of blockage and other issues. In that 20-year term, there has to be flexibility so that innovation is not actually hampered by legal shenanigans in the patent system.
