Prior work suggests that more valuable patents are cited more and this view has become standard in the empirical innovation literature. Using an NPE-derived dataset with patent-specific revenues we find that the relationship of citations to value in fact forms an inverted-U, with fewer citations at the high end of value than in the middle. Since the value of patents is concentrated in those at the high end, this is a challenge to both the empirical literature and the intuition behind it. We attempt to explain this relationship with a simple model of innovation, allowing for both productive and strategic …

The Leahy-Smith America Invents Act, the most significant patent law reform effort in two generations, has a dark side: It seems likely to decrease the patenting behavior of small inventors, a category which occupies special significance in American innovation history. In this paper we empirically predict the effects of the major change in the law: a shift in the patent priority rules from the United States’ traditional “first-to-invent” system to the predominant “first-to-file” system. While there has been some theoretical work on this topic, we use the Canadian experience with a similar change as a natural experiment to shed …
