GUI

"The graphical user interface, or "GUI" (IPA: [ˈɡuːi]), is a computer interface that uses graphic icons and controls in addition to text. The user of the computer utilizes a pointing device, like a mouse, to manipulate these icons and controls. This is considerably different from the command line interface in which the user types a series of text commands to the computer."-Wiki.

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 the appeal to the U.S. Supreme Court by Apple was denied..." Wiki.
