Nintendo sues Nyko over wireless Nunchuk

Nintendo has filed a lawsuit against peripherals manufacturer Nyko after alleging that the firm's wireless Nunchuk infringes its patented design.

The move, which marks the first time Nintendo has taken legal action over a Wii accessory, saw the case filed at the US District Court.

Nintendo alleges that Nyko's controller "wholly appropriates the novel shape, design, overall appearance and even the colour and materials used in the Nintendo Nunchuk controller".

Denise Kaigler, a vice president at Nintendo of America, said: "While Nintendo supports the creation of innovative games and products used with our game systems, we cannot allow third parties to infringe our intellectual property rights."

Responding to the allegations, Nyko spokesman C.C. Swiney told Bloomberg: "We have not knowingly violated anyone's intellectual property and we're still examining this."
