That was one of the few (only?) patents that MS actually admitted to. Balmer made a bunch of really vague public threats where he refused to be drawn on which patents Linux (not Gnome, or KDE, or Gnome or KDE using distros specifically) he implied were infringing, most of which never materialised into any court cases or patent deals. Did they enter any other deals than the Novell deal, which involved MS paying Novell 11x what Novell paid MS?
