<human>: Condense the text into a few key points

I've been trying to investigate a patent that seems to not exist, the "inventor" showed a copy of the patent application, and on his site he has had "Patent Pending" for over 2 years and to my understanding, patents don't stay pending for THAT long. I have searched for the inventor's name, and have found nothing, I have searched for the title, and found nothing, I have searched for CPV, again, turns up nothing.

The thing he claims to be patenting isn't even his idea, it's pretty publicly used and there just doesn't seem to be a patent in existence for it. I searched through a few hundred patents for generic terms that his patent would fall under on Google Patents, PatentGenius, and the .gov site. 

My question is, is it possible that his patent WOULDN'T be available through any of those search methods, is it possible that his patent has been pending for 2 years? If it isn't possible than how would I go about fixing this problem? His "patent pending" that doesn't seem to exist screws with a number of (good) people's business with legal threats that he makes.
<bot>: Guy claims to have patent pending on something, but I can't find anything to back his claims on any public database. What should I do?
