The impact of patent rights on international trade: evidence from Canada

The extent to which Canadian manufacturing exports are sensitive to national differences in patent rights are examined. The conclusion is that, overall, Canadians tend to export more to those countries where their patent rights are highly safeguarded. Stronger patent protection induces Canadians to export relatively more to high-income countries than to low-income countries. In addition, the effect of stronger patent rights is to increase exports to those countries that pose a strong threat of imitation and to reduce exports to those countries that pose the weakest threat of imitation.
