The Korean Times is reporting that the Korean branch of Nintendo has filed suit against several websites over copyright issues. The suits come just nine months after Nintendo first opened up the Korean market (officially) with the introduction of the Nintendo DS. From the article: "'They infringed on our copyright by posting Nintendo's game titles through the Internet without our permission,' a Nintendo spokesperson said. '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.' She declined to comment on how many sites and people are involved in the piracy suit. The legal action came after Mineo Koda, the Japanese chief executive of Nintendo Korea, had expressed concern about the lingering problem of piracy in South Korea that he said would pose a challenge to his company's business here."
