This means that the patent that Xerox has on using hyperbolic geometry to lay out trees encompasses prior art and is invalid.
Has the Patent Office or a court ruled it invalid, or is this just somebody's personal legal opinion? Josh Cherry 16:06, 27 Jun 2004 (UTC)
Since nobody has come forth to defend this, I have removed what seems to be the writer's personal opinion. If somebody important is publicly making this claim, we can put back something like "Xyz alledges that...." Josh Cherry 00:05, 6 Jul 2004 (UTC)
