WebMink writes "It used to just be speculation, but the numbers are now in — patent trolls are costing America jobs and economic growth. Newly-published research using data commissioned by Congress shows big rises in patent troll activity over the last five years — from 22% to 40% of all patent suits filed, with 4 out of five litigants being patent trolls. Other papers show that jobs are being lost and startups threatened, while VC money is just making things worse by making startups waste money filing more patents. Worst of all, it's clear this is just the tip of the iceburg; there's evidence that unseen pre-lawsuit settlements with patent trolls represent a much larger threat than anything the research can easily measure.
At least there is a little good news though; the fact Congress commissioned research on patent trolls means there are legislators taking the problem seriously at last,"
