Daum Communications Corp, South Korea's top Internet portal, said on Monday it was suing Microsoft Corp and its Korean unit for alleged unfair business practices related to instant messaging software.
"Microsoft used its dominant market position by bundling its Instant Messenger program to its Windows XP operating system and that has caused significant damage to Daum," Daum said in a statement. "By using its dominance in PC operating systems, Microsoft is excluding rivals from Internet messenger markets."
Daum, which has its own messaging service, said it had filed a 10 billion won ($8.74 million) indemnity suit at the Seoul District Court.
Officials at Microsoft Korea could not immediately be reached for comment.
