It's not just Apple's ubiquitous click-wheel that Quantum Research is bothering Apple about these days, Quantum is also fussing about the iPhone's touchscreen technology. "We will be looking very carefully at the iPhone," says Duncan Bryan, licensing director at QR. And wouldn't you know: "The description of the iPhone suggests it uses a rear-surface touch screen, and has proximity sensing which can tell if it is held to the ear. That's a QR capability." No formal lawsuit has been filed yet, but based on Apple's complete denial and counterclaims of QR's December 2005 click-wheel allegations, we're guessing it won't be backing down on this one anytime soon. Apparently this "charge transfer capacitive sensing" stuff has been licensed to Motorola and was invented by QR's founder and CEO Hal Philipp. Usually we'd be content to sit back and watch, but all these Apple-related lawsuits and copycats are getting a little tried -- remember those good old fashioned RIM / NTP days?
