I am a bit surprised that most comments here focus on whether the guy's genuine or not.
What surprised me, in a bad way, is that to challenge a patent you have to have 6k USD to throw away plus the expertise and time (which the article estimates at 60k USD).
IMHO, if the patent ends up overturned, the patent holder should be liable for those costs. In fact, I can't think of any reason why it shouldn't be that way. Can you?
