Talk:Hyperbolic tree

It is said on some webpages that the patent on the Hyperbolic tree has been revoked. If this is true, this should be added. 16:07, 19 February 2010 145.94.173.174
 * Found no solid source. Indications are that Xerox released the patent, some time back. --Abd (talk) 16:21, 19 February 2010 (UTC)

Well, we should have a link to the original patent at least. If it has been released, I agree that would definitely need to be included. —Preceding unsigned comment added by 24.182.58.154 (talk) 18:07, 5 November 2010 (UTC)
