Patent trolls as scientific experiment

I’m sure it’s no secret how I feel about Patent Trolls (those companies that exist solely to sneak up on unsuspecting companies with an arsenal of patents in order to profit), but I think it’s interesting to think of cases like the NTP vs. Blackberry case in the light of scientific experimentation of how patents will devolve the business community. Perhaps there is truth in the saying that maybe your only reason for existing is to warn others.
