The researchers, James Bessen, Mike Meurer, and Jennifer Ford have managed to compile the costs of patent trolling. This amount has been totaled up since 1990, and it seems that they have managed to come up with a staggering cost of $500 billion for US companies. In fact according to their calculations, in the past four years, the average cost of patent trolling has risen to $83 billion annually. Ouch.
Take note that it seems that how these researchers arrived upon that figure is based on tangible costs, such as legal fees and settlement payouts. They did not factor in things such as employee distraction (which could lead to lower productivity levels), legal uncertainties and the time and effort needed to do product redesigns. The figure was also based on publicly held companies and not smaller, private companies who might have had to shut down and go out of business as they could not afford a costly legal battle. It appears that if all those factors were taken into account, we’re guessing that the figure would have been a lot more.
