Microsoft's anti-trust trial resumes today after a 13 week respite, and the players are entering that all important rebuttal phase where they have three witnesses apiece to clinch, or lose, the arguments.
The trial looks set to run for several months, with neither side certain of victory.
IBM senior executive Garry Norris is expected to testify that Microsoft made threatening noises about not selling a Windows licence to IBM to sell with its hardware.
AOL's David Colburn, senior vice president of business affairs, testified for the Justice Department earlier this year, but Microsoft intends to argue that AOL's November's acquisition of Netscape is proof that the industry is not dominated by Redmond and there will always be new entrants and challengers.
Whoever wins or loses, the outcome is unclear. If Microsoft loses, some commentators advocate breaking it up; others want to see it license Windows to other companies, much as IBM was compelled to do many years ago with its mainframe operating system.
