From the NYTimes:
In the last five years, IPNav has sued 1,638 companies, according to a recent report by RPX, a patent risk management provider, more than any other entity in the patent field. “To get companies to pay attention, in some percent of the market, you need to whack them over the head,” Mr. Spangenberg said. “In our system, you can’t duel, you can’t offer to fight in the street, which would be fine with me.”
…Mr. Spangenberg is likely to open the conversation on a diplomatic note, but if you put up enough resistance, or try to shrug him off, he can also, as he put it, “go thug.”
He demonstrated what that sounds like in a brief bit of role-play recently, sitting in the apartment he is renting for the summer in Paris near the Arc de Triomphe. His voice dropped, the curse words flowed, and he spoke with carefully modulated menace.
“Once you go thug, though, you can’t unthug,” he explained, returning to his warm and normal tone. “Actually, you can unthug, but if you do that, you can’t rethug. Then you just seem crazy.”
