During its SCO Forum conference of 2003, The SCO Group (SCO) showed several examples of allegedly illegal copying of copyrighted code into Linux. The open source software community quickly debunked most of them. One example showed some Unix code within some of SGI's Linux contributions. The Linux maintainers stated that this code had already been removed from Linux before the example had been revealed — not because it was infringing, but because it had needlessly duplicated some functions already present in Linux. SGI and other analysts also confirmed that the code had never infringed.
