About a month ago we published an article in response to a widely-reported study, conducted by Boston University law researchers James Bessen and Michael Meurer, which concluded that, in 2011, patent ‘trolls’ imposed a $29 billion burden on innovation in the US, and that this is further proof that the patent system is ‘broken’ (see A $29 Billion US Troll-Tax or Just Another Statistical Smokescreen?).
Our interest was piqued by the sheer unbelievability of the quoted cost, and in addition to questioning the plausibility of the conclusion we raised three main criticisms of the assumptions and methodology in the Bessen and Meurer study:
Our interest was piqued by the sheer unbelievability of the quoted cost, and in addition to questioning the plausibility of the conclusion we raised three main criticisms of the assumptions and methodology in the Bessen and Meurer study:
- there is ‘selection bias’ in the sources of the data used in the study;
- the study makes no meaningful distinction between different types of non-practicing entity (NPE), and thus fails to distinguish between deadweight costs (which are genuine burden on the economy) and transfer costs (which are not); and
- the statistical methods and assumptions employed in the study are decidedly opaque, and fail to place any estimate of confidence on the $29 billion figure.
