Launched earlier this year, Nintendo of Korea has taken its first action against piracy of games in the country, The Korea Times reports. The Korean branch of Nintendo announced today it has filed suit against an unidentified number of users who shared Nintendo software with P2P programs or on websites, on the basis of copyright infringement.

Nintendo went through the Supreme Prosecutors' Office in Seoul to file the case, the first time the company has sought legal recourse for piracy in South Korea. "The legal action was taken against only some sites and users this time but we will take further measures if such a violation continues to take place," a Nintendo rep told The Korea Times.

The Seoul-based branch of Nintendo would not reveal the specifics of the case or how many people or sites were involved. Nintendo has gone after counterfeiters in Taiwan and China for selling hard copies of pirated games, but not for sharing games using P2P software or other websites.
