Apple vs. microsoft: landmark copyright lawsuit

In 1994, a landmark copyright infringement lawsuit took place between Apple Computer Inc. (now Apple Inc.) and Microsoft Corporation, along with Hewlett-Packard Co. The case centered around the use of visual graphical user interface (GUI) elements that were similar to those in Apple's Lisa and Macintosh operating systems.

Background

In the late 1980s, Apple had agreed to license certain parts of its GUI to Microsoft for use in Windows 0. However, when Microsoft made changes in Windows 0 that included overlapping windows and other features found in the Macintosh GUI, Apple filed a lawsuit. Apple added additional claims to the suit when Microsoft released Windows 0.

Apple claimed that the look and feel of the Macintosh operating system, as a whole, was protected by copyright. They argued that each element of the interface, such as windows, icons, and menus, was not as important as the combination of all these elements. The court insisted on an analysis of specific GUI elements that Apple claimed were infringements.

Midway through the suit, Xerox also filed a lawsuit against Apple, alleging that the Mac's GUI was heavily based on Xerox's. Xerox had invited the Macintosh design team to view their GUI computers at the PARC research lab, which had influenced the development of the Macintosh GUI. However, Xerox's case was dismissed for various legal reasons.

Court case and ruling

The district court ruled that a standard of virtual identity between Windows and the Macintosh was required for Apple to prove copyright infringement. Apple believed this standard was too narrow and argued that a more broad look and feel should be sufficient. Both parties agreed that a jury trial was unnecessary given the rulings, and Apple filed an appeal to the Ninth Circuit Court of Appeals.

The appeals court affirmed most of the district court's ruling, stating that the similarities between Windows and the Macintosh were either covered by the licensing agreement or were basic ideas expressed in a GUI. The court also highlighted that many of Apple's claims failed on an originality basis, as Apple had licensed many of its representations from Xerox.

The court's ruling established that the dissection of a GUI into expression and ideas is vital to any copyright decision. It also avoided setting a far-reaching precedent on look and feel copyright.

Impact

The ruling in the Apple vs. Microsoft case was based largely on the original licensing agreement between the two companies. As a result, the case was more of a contractual matter than a copyright law issue. However, it did establish the importance of analyzing specific GUI elements in copyright cases.

In 1997, all remaining infringement questions against Microsoft regarding the Lisa and Macintosh GUI, as well as Apple's quicktime piracy lawsuit against Microsoft, were settled in direct negotiations. Apple agreed to make Internet Explorer its default browser, and Microsoft agreed to continue developing software for the Mac. Both parties also entered into a patent cross-licensing agreement.
