The iPod/Nike Sports Kit that enables your Nano to gauge statistics about your workout via a Nike shoe sensor is under attack by wireless sporting company, PhatRat. PhatRat, based in Niwot, Colorado, is known for extreme/ hi impact sports performance devices like the airRat, a device for measuring sports performance while snowboarding, skiing or riding a BMX bicycle.

PhatRat claims in a lawsuit that both companies are infringing on technology developed by them in transmitting data from footwear to wireless devices, in their case a watch. The patent at issue is entitled “shoes employing monitoring devices, and associated methods.”

PhatRat is seeking a cash compensation and a court order prohibiting Nike/Apple’s production.

“Nike is aware of the complaint and is reviewing the allegations alongside our own intellectual property rights,” a spokesman for Beaverton, Oregon-based Nike told Bloomberg.
