Chinese IT company Founder Electronics Co., Ltd. is suing California-based Blizzard Entertainment for 100 million yuan, claiming lost earnings from the unauthorized use of its fonts.
A statement from Founder Electronics said five fonts from its database were used without authorization in the popular on-line fantasy game World of Warcraft (WoW), resulting in losses of one billion yuan.
Founder Electronics has launched the lawsuit against Blizzard Entertainment, a unit of French media and telecoms company Vivendi, at the Beijing Municipal Higher People's Court.
Founder Electronics is the largest provider of Chinese fonts in China, the statement said.
The font database was part of the company's E-Publishing system, which was used by 90 percent of the international Chinese newspaper industry, the statement said.
Observers said the damages sought by the Chinese company were among the largest ever for an intellectual property suit in China.
Shanghai-based IT company The9, which runs WoW in China, refused to comment on the suit on Tuesday evening.
The monster-killing game, first launched in 2004, is one of the most popular on-line role-playing games involving multiple players. It was officially launched in China in June 2005.
Founder Electronics is a wholly-owned subsidiary of Founder Group, which has 20,000 staff and five listed public companies on the securities exchanges of Shanghai, Shenzhen, Malaysia and Hong Kong. (One U.S. dollar equals 7.5845 yuan)
