There have been significant developments over the last few years in Canadian and United States courts in the calculation of damages for patent infringement. This seminar, hosted by NERA in Toronto on 9 December 2009, focused on the economic and business principles underlying the appropriate and rational determination of damages, and the extent to which courts in North America appear to be imposing a rational basis for damage awards. The principles discussed at the seminar were those that are generally applicable in the valuation of intellectual property. Speakers included Bruce W. Stratton, a Partner at Dimock Stratton LLP, and NERA Senior Vice Presidents Mark Berenblut and Dr. Alan Cox. Vice President Bradley Heys served as moderator.
