 Some critics claimed that Apple was really attempting to gain all intellectual property rights over the desktop metaphor for computer interfaces, and perhaps all GUIs, on personal computers.Apple lost all claims in the lawsuit, except that the court ruled that the "trash can" icon and file folder icons from Hewlett-Packard's now-forgotten NewWave windows application were infringing.The lawsuit was filed in 1988 and lasted four years; the decision was affirmed on appeal in 1994, and Apple's appeal to the U.S. Supreme Court was denied.
