Usually these cases start when a would-be competitor accuses the monopolist of taking anti-competitive actions. First step would be to review these accusations, if they exists.
Speculating whether they "might do something" without specifics seems fruitless.
The 1999 "Findings of Facts" in the US vs MS case should give a good idea of what is needed. It is quite readable, written in plain language, and totally ignored by the pundits who commented the case at the time.
