Nintendo and Nyko in Nunchuk Fight

Nintendo has sued Nyko Technologies Inc. over its Wii accessory, the wireless Kama Nunchuk. In a suit filed in US District Court in Seattle, Nintendo alleges that Nyko’s remote "wholly appropriates the novel shape, design, overall appearance and even the color and materials used in the Nintendo Nunchuk controller." Nyko has denied any violation of Nintendo’s intellectual property.

In addition to accusing Nyko of trademark and patent violations, Nintendo is seeking damages and profits earned as a result of the infringements.

Nintendo’s Wii Nunchuk is the motion-sensitive controller used with the popular system, but is attached to the main controller by a wire. Nyko also makes other peripherals for use with the Wii, including another wireless remote and a wireless Telecaster-ish guitar for GHIII.
