"The new issue of IAM is now available on-line to the magazine’s subscribers. The cover story focuses on Patent Failure: How Judges, Bureaucrats and Lawyers Put Innovators at Risk. Written by James Bessen and Michael Meurer, the book has attracted a great deal of attention across the world because of its central message; namely, that the US patent system is failing to incentivise innovation and, in fact, is actually acting as a disincentive to the inventive process. While many have praised Bessen and Meurer’s work, others have been fiercely critical; claiming that the two authors fail to understand how patents work and that because of this the book is fundamentally flawed. We decided to put Bessen and Meurer in contact with one of their critics, Silicon Valley-based lawyer Craig Opperman. The result was a fascinating discussion."
