As patent protection afforded outside the United States becomes increasingly lucrative, the time is ripe to consider recalibrating the duration of patent protection afforded within the United States. Wesley D. Markham takes an empirical approach to this policy-based issue. Specifically, he develops a new metric, the “global patent term” (GPT), and uses it to analyze the patenting strategies of three firms in three very different industries. Based on the results of these three case studies, he concludes that patent globalization is more lucrative in some industries than others. Accordingly, the United States should seriously consider technology-specific patent terms to ensure all firms receive appropriate incentives to innovate.
