Blizzard is suing Michael Donnelly, the creator of the MMO Glider program, which performs key tasks in the game automatically, such as fighting and other game actions. Both sides have submitted legal summaries to the US District Court in Arizona. Blizzard says Glide is a software bot which infringes the company's copyright and potentially damages the game. In its legal submission to the court last week, the firm said: "Blizzard's designs expectations are frustrated, and resources are allocated unevenly, when bots are introduced into the WoW universe, because bots spend far more time in-game than an ordinary player would and consume resources the entire time." Blizzard argued that Michael Donnelly's tool also infringed the End User License Agreement that all parties have to adhere to when playing the game. As result Blizzard wants Michael Donnelly to stop selling Glider and return all profits that he made from its sales. More than 100,000 copies of the tool have been sold for the time being. Mr Donnelly says his tool does not infringe Blizzard's copyright because no "copy" of the Warcraft game client software is ever made. The two parties are now awaiting a summary judgement in the case.
