On July 25, 1989, Apple faced a legal defeat against Microsoft in a copyright infringement lawsuit concerning the "look and feel" of the Macintosh and Windows operating system. Apple filed 189 counts of infringement related to Windows 2.0.3, but the judge dismissed 179 of these claims, allowing Windows to grow rapidly. The origins of the conflict began when Microsoft proposed a licensing agreement to Apple in 1985, which was rejected. Following this, Microsoft launched Windows 1.0 in November 1985, leading to tensions as Windows 2.0 more closely resembled the Macintosh interface. Apple filed a lawsuit on March 17, 1988, claiming copyright violations. The judge ruled that the existing licensing agreement covered many elements of Windows, contributing to a long-standing rivalry between the two companies and establishing a legal foundation for Windows' dominance in the 1990s.
