REDMOND, Wash. (
said it plans to appeal a Chinese court ruling it has infringed intellectual property rights of a Beijing-based software firm.
"Microsoft respects intellectual property rights. We use third party IPs only when we have a legitimate right to do so," the software maker said in a statement.
The ruling orders Microsoft to stop selling versions of its Windows operating systems that use two Chinese fonts developed by Chinese software company Zhongyi Electronic. The company will have to halt sales of Chinese versions of Windows 98, Windows 2000, Windows XP and Windows Server 2003.
The court ruling says Microsoft's use of the Chinese fonts wasn't covered under a license agreement between the two software companies.
The ruling renews worries among foreign patent experts about China's management of intellectual property rights disputes, notes the
. Microsoft has been fighting for the protection of its own rights in the mainland where most operating systems currently in use are reportedly pirated versions.
