UK-based touch-sensor specialist Quantum Research has filed another lawsuit against Apple, this time regarding the touch-screen technologies used in the iPhone.
The company said earlier this week that it may file a second lawsuit against Apple, claiming that some technologies in the iPhone infringe on the companies patents.
"We will be looking very carefull y at the iPhone," 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."
Quantum Research's original lawsuit dates back to December 2005 when it filed a formal complaint regarding the capacitive sensing technology used in the iPod click wheel.
Apple replied to the mentioned suit "denying all material allegations" as well as filing counter claims.
"There are settlement discussions going on but I believe it will go to trial later this year,” Quantum’s Philipp stated last month.
