This is cool, but there are companies which do prior art bounties out there, I wonder why they didn't use on of them? Also, they must be extremely serious about this. A $50k prior art budget is high - like very high - for this kind of thing. You can get a search firm to do a decent job for $1-2k and a bang up job for $10k-ish. So by throwing $50k into the pot, they're showing that they're out for blood.
