Through Graphical user interface, Operating system and Supreme Court of the United States

Background

Apple Inc. had agreed to license certain parts of its GUI to Microsoft for use in Windows 1.0, but when Microsoft made changes in Windows 2.0 adding overlapping windows and other features found in the Macintosh GUI, Apple filed suit. Apple added additional claims to the suit when Microsoft released Windows 3.0.

Apple claimed the "look and feel" of the Macintosh operating system, taken as a whole, was protected by copyright, and that each element of the interface (such as the existence of windows on the screen, the rectangular appearance of windows, and their ability to be resized, overlap, and have title bars) was not as important as all these elements taken together. After oral arguments, the court insisted on an analysis of specific GUI elements that Apple claimed were infringements. Apple listed 189 GUI elements; the court decided that 179 of these elements had been licensed to Microsoft in the Windows 1.0 agreement and most of the remaining 10 elements were not copyrightable —either they were unoriginal to Apple, or they were the only possible way of expressing a particular idea.

Midway through the suit, Xerox filed a lawsuit against Apple claiming Apple had infringed copyrights Xerox held on its GUIs. Xerox had invited the Macintosh design team to view their GUI computers at the PARC research lab; these visits had been very influential on the development of the Macintosh GUI. Xerox's lawsuit appeared to be a defensive move to ensure that if Apple v. Microsoft established that "look and feel" was copyrightable, then Xerox would be the primary beneficiary, rather than Apple. The Xerox case was dismissed, for a variety of legal reasons, most notably that Xerox "had waited too long to file a copyright infringement case and had to resort to a weaker charge of unfair competition".
