Yep, I agree.  It was the ferping lawyers who kept "adding value" to try to broaden it.  What we (the inventors) wrote up was nice and clean.  It does have some new and novel technical approaches that we really did come up with...and could find no prior art for.  Then the lawyers got to it.  A true example of what's wrong with software patents these days.
