UK-based Quantum Research Group has filed a lawsuit against Apple Inc. over patent infringement of the company's capacitive sensing technology. The touch sensor chip company says that Apple's iPod makes use of the technology via the iPod's now-famous click wheel. "Some are based on Cypress' PSoC chip and used in a way we believe infringes our patent," CEO Hal Philipp told Electronics Weekly. Interestingly, the suit was actually filed just over a year ago in December of 2005 but only came to public light recently when Apple revealed that it had filed an answer to the suit. Apple's response was, of course, that they did not infringe on any patents. In addition to the company's formal denial of all allegations, it also filed a countersuit against Quantum for noninfringement.
