Which Patent Systems Are Better For Inventors?, James Bessen, Grid Thoma

International comparisons of patent systems are essential to harmonization treaties and to analyze economic growth. Yet these comparisons often rely on little but conventional wisdom. This paper develops an empirical method to compare the economic strength and quality of patent systems by using renewal analysis of matched patents in different countries (same patent family). Comparing patents on the same inventions filed at the EPO for Germany and in the US, we find that the German patents generate substantially greater market power than their US equivalents, especially for small inventors. Also, the average US patent has relatively lower economic value (“quality”).

The Federal Circuit’s expansion of patentable subject matter in the 1990s led to a threefold increase in software patents, many of which contain abstract ideas merely tethered to a general-purpose computer. There is little evidence, however, to suggest this expansion has produced an increase in software innovation. The software industry was highly innovative in the decade immediately prior to this expansion, when the viability of software patentability was unclear and software patents were few. When surveyed, most software developers oppose software patenting, and, in practice, software innovators tend to rely on other tools to capture market share such as first-mover …

The debate over "patent trolls"' is raging at full tilt and its fury is stoked by fundamental questions about patent assertion. Both sides are struggling to understand which patent assertion practices are consistent with the purpose of patent rights and which are abusive and result in net social costs. This Article addresses patent assertion concretely through empirical analysis of actual infringement awards. In particular, this Article studies all awards granted for findings of patent infringement in U.S. district courts between 1995 and 2011, and, with targeted analyses, focuses on cases involving patent assertion entities ("PAEs"). This Article specifically investigates certain …
