Apple/Quantum spat takes another twist

The patent lawsuit between industry behemoth Apple and plucky little innovation firm Quantum (guess who’s side I’m on) is really on a roll. The story kicked off in January with Apple facing a patent claim over iPod touch sensor technology. That was good stuff, but it got even better earlier this month as the sensor firm warned Apple over its iPhone design. Duncan Bryan, licensing director at Quantum Research (QR), told Electronics Weekly:

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.

It’s the charge transfer technology invented by Quantum that is at the heart of the lawsuit. However, now it seems Quantum is playing down the iPhone issue, and will wait until the iPhone goes on public sale before taking it any further.

“Quantum has no knowledge of any infringement by Apple of Quantum’s patents in regard to the iPhone or any other product other than those products alleged to be infringing in our 2005 lawsuit against Apple and Cypress Semiconductor, specifically the Powerbook trackpad, Mighty Mouse, and iPod Nano scroll wheel”
