Alex Tabarrok’s pictorial commentary on patent policy, drawn on a napkin, posits that the current patent system is somewhat too strong and thereby decreases innovation (the link to his original post is below). I have to say, however, that I don’t think patent strength is the problem. The problem is that the growth in patent applications over the last two decades has vastly exceeded the growth in resources available to the patent office, resulting in 1) long delays between patent application and granting (which can render patents completely pointless in fast moving industries), and 2) inadequate ability to examine the patent applications for novelty, usefulness and non-obviousness. This lowers the value of good patents (because they aren’t granted quick enough or may be fallaciously challenged) and increases the likelihood of bad patents being granted. As a result, for many individuals and firms, the expected net gains from manipulating the patent system for the purposes of extortion (hostage taking, patent trolling) now exceeds the expected net gains from using the patent system to actually innovate.
It’s difficult to assess how patent strength affects innovation without first making sure that patents are being granted and used the way the system had originally intended.
