I am going to use a foul word here, which normally I would not do in a forum, because it is generally not appropriate, but...
This Katzer guy is in the running for being the biggest douche in the history of computing.
I really hope they can wring every last nickel out of him, or at least that karma gets him.
I also would hope that deliberately misleading the US Patent Office for the purpose of preying on innocent people is a felony, and the Katzer will find his Karma in federal prison, but I guess that is too much to hope for.
It's too bad, if he stole a stereo from Best Buy he would be in jail, but stealing thousands of dollars and thousand of hours from someone won't get him there
