Good answer... Moore & Fish's original patent app.... you know the one made in 1989.. the one broken up into ten patents including the 336. I believe that patent app cited one of the prior art references mentioned by Pubpat.. so I believe, that one of the prior arts that you say were not cited in the 336, was actually cited in that initial 1989 Fish/Moore patent app... that was broken up into ten patents including the 336.... follow?
