Coming events in the Justice Department's antitrust case against Microsoft Corp.:

_Sept. 14: Prosecutors and Microsoft are to submit status reports to U.S. District Judge Colleen Kollar-Kotelly describing the issues they want to pursue in penalty discussions and a schedule for proceedings.

_Sept. 21: Both sides will appear before Kollar-Kotelly about the schedule. If the two sides don't agree on a timeline, the judge will set one herself.

_Early October: The Supreme Court will return from its recess and is expected to decide whether it will take up Microsoft's appeal. Microsoft lawyers say the former judge, Thomas Penfield Jackson, was biased and want his verdict to be tossed out. If the justices take the case, it probably will be argued next year. Prosecutors oppose the appeal on the ground that a federal appeals court already decided the question.
