The Korea Fair Trade Commission (KFTC) is likely to deliver a ruling in an antitrust case against Microsoft next week, it said on Wednesday.

The KFTC said a week ago that it was likely to deliver its verdict against the software maker today but its panel failed to complete deliberations this morning, prompting a delay until at least the next meeting in one week, according to Lee Hwang, senior investigator for the Microsoft task force at the KFTC.

He said there is a "high probability" that the KFTC will announce its findings after its next meeting, which is scheduled for 7 December.

The KFTC case is related to a complaint filed in September 2001 by Daum, a Korean internet portal operator. Daum complained about Microsoft's bundling of Windows Messenger with the Windows operating system. Daum operates its own instant messenger platform in South Korea that competes with Microsoft's offering.

Microsoft settled the dispute with Daum earlier in November with a payment of $30m (about £17.5m). That was made up of a $10m (£5.8m) cash payment, an advertising contract valued at $10m, and a further package of measures valued at $10m including "marketing and promotional opportunities", the two companies said.
