Patent trolls are a symptom of the disease that is our horribly broken patent system, which also serves to stifle innovation and protect the interests of large, entrenched businesses at the expense of everyone else. Unfortunately, instead of working to fix our broken patent system, we are doubling down and trying to impose it on a global basis via the TPP (often categorized as a "free trade" deal when it is in fact quite the opposite) and other misbegotten treaties.
There is one US candidate who is against TPP, but unfortunately, I highly doubt anyone nearby understands the devastation that software patent trolls cause on the tech industry.
