A federal appeals court has scheduled a hearing next month to decide whether to uphold a ruling that would force Microsoft to stop selling Word in its current form.

A district court judge last week issued an injunction that would halt sales of any version of Word that includes a custom XML function that was found by a jury to infringe on a patent from Canada's I4i. In May, that jury also dinged Microsoft with $200 million in damages, an amount that the judge hiked to more than $290 million at the same time he ordered the injunction, which he scheduled to go into effect 60 days after the Aug. 11 ruling.

In a statement, I4i said that Microsoft's appeal will be heard on Sept. 23. Microsoft had asked for an expedited hearing on the matter.
