Basically it went like this:
Episode one (2003):
SCO: ZOMG IBM YUO STOLED MILLIUNZ LIN3Z OUR KOD3Z AND PUT DEM IN LEENOOKS! WE R SOOOO GONNA SUE ALL LINUX US0RZ!
Episode two (2003-2007):
IBM: no we didnt!
SCO: yes u did!
IBM: no we didnt!
SCO: yes u did! ps novell u stol3d our unix tradm4rk
Episode three (summer 2007):
Judge: Only around 350 lines of possibly infringing code have been found, however they're all trivial #includes, #defines and comments. It is quite possible that these were independently written, and Novell pwns the unix trademark.
SCO: omg hax! lag! crappy server! gay admin!
IBM: pwnt!
Novell: lol u had crappy baes!
