This article details a recent case that took place in a Chinese court. The plantiff, Zhongyi, claimed to have rights over the Chinese character fonts that are used by Microsoft, which are in their operating systems. The claim is that Microsoft sought permission for licensing these fonts in Windows 95, which Zhongyi agreed to. However, after this was over, Microsoft went on to use this same font set in Windows 98 and Windows XP, and the plantiff is aiming to stop production of these products which contain his illegally used font. It is agreed that this is more of an issue over the scope of the licensing agreement than anything.

The Chinese courts ruled that Microsoft was guilty of copyright infringement, and ordered them to stop producing versions of the operating systems with these specific fonts.
