Apple sued over Click Wheel touch sensor technology

Quantum Research Group has sued Apple, claiming technology used to make the iPod’s Click Wheel infringes on a touch sensor patent it holds. “We are suing Apple over charge-transfer technology in iPods,” said Quantum CEO Hal Philipp. “Some are based on Cypress’ PSoC chip and used in a way we believe infringes our patent… There are settlement discussions going on but I believe it will go to trial later this year. I am hoping iPhone does not contain Quantum-patented charge-transfer technology.” The legal action against Apple was initiated in December 2005 but has been kept under wraps until now. Apple recently filed an answer “denying all material allegations and asserting numerous affirmative defences.” The company also filed “counterclaims for non-infringement and invalidity” in July.
