The9, Chinese publisher of original MU(Chinese title: 奇迹/Miracle), announced that they will reveal the test schedule for MU2 on the 5th of April. That made Webzen, the developer of the original MU, in panic.
The9 announced MU X, the sequel of MU as they said, at 2009 Chinajoy and started developing. However, MU X is developed by The9 itself without getting any permission from the original creator Webzen. When Webzen complained, The9 decided to change the title of the game as 奇迹傳說(Miracle Legends). Now, The9 announced that they are going to change the game title as MU2(奇迹2) because the Chinese government approved The9 to use MU2(奇迹2).
Webzen sued The9 for the returning of trademark right in Korea in 2010 and won. However, they did not sued The9 for it in China because they have already won the lawsuit in Korea and did not want to continue disputing with their partner any more. That has made the trademark issue arising again.
Now, Webzen is agonizing how to react. According to Webzen, some artworks that The9 distributed to Chinese media are belong to Webzen. The 2nd round of Trademark dispute between Webzen and The9 has just begun.
