Apple is taking action again to protect its intellectual property. The company has accused Iops, a Korean portable music player manufacturer, of of its popular iPod mini music player. Iops, the fifth largest MP3 player seller in South Korea, said Thursday that it had received an official complaint from Apple in October which demanded the Korean firm stop manufacturing and selling its two MP3 player models, the Iops Jock and Iops Z3, according to The Korea Times: "Apple insists that the Jock and Z3 models copy the exterior design and case colors of the iPod Mini, especially the layout of a display screen and a round-shape control button on the front panel. Iops rebuffed the claim, saying it is waiting for further action from Apple. The Korean firm said that it is expecting an international legal suit from Apple.
