Economists and analysts cite a number of studies that find "the more R&D a firm performs, the more likely it is to be hit with a patent lawsuit" and "associates lawsuits from PAEs with a decline of billions of dollars of venture capital investment."

Fortunately for patent trolls and unfortunately for companies attempting to innovate, patent lawsuits are cheap to file but expensive to defend.
Congress has already tried and failed to reform patent law twice in the past 5 years. However, recent court battles and media controversy has alerted and informed both political parties and the three branches that patent reform is necessary, if just to provide transparency to the inner workings of patents and their trolls.
