Sensor Firm Warns Apple Over iPhone

February 23rd, 2007

“We will be looking very carefully at the iPhone,” is the warning to Apple from Southampton-based touch sensor specialist Quantum Research, which already has one lawsuit proceeding against Apple for patent infringement, and is prepared to bring another. “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,” Duncan Bryan, licensing director at Quantum Research (QR), told. If Apple has used charge transfer technology, QR’s patented technology, to give the iPhone that capability, then Apple could be infringing the firm’s patent. Charge transfer capacitive sensing was invented by QR’s founder and CEO Hal Philipp. It has licensed Motorola, which uses it in its mobile phone keypads, and also STMicroelectronics.
