Eileen also has market-leading experience with patented medicines and oversight of Canada’s Patented Medicines Prices Review Board (PMPRB). Eileen also represents investors and companies looking to finance or invest in companies with intellectual property and regulatory assets, as well as companies looking to acquire or divest such assets.
