"Patent trolls make good poster children for the patent system’s dysfunctions, but focusing too much on them ignores the fact that abusing the patent system is a game played by large companies as well. For example, Verizon managed to extort tens of millions of dollars from Vonage to settle a lawsuit over an absurdly broad Internet telephony patent. Verizon, of course, isn’t a “patent troll,” but a competitor interested in hobbling an up-and-coming competitor. Any patent reform needs to address the Verizons of the world too, not just the NTPs."
