I wonder what the patent is? Also if it is a BS one where it is a component purchased from a company licensed to build it. Such as any WiFi or cellular radio patent.
The particular patent talked about in that article is
6,246,862.
It's a patent on using a sensor to disable the touchscreen when you put a phone to your face. On the surface, that would seem to mean Apple owes Motorola for using that technique on the iPhone. (Or that Motorola could get a ban on iPhone imports.)
However, the way the claims are worded, it seems to only cover if the sensor circuit actually disables the touchscreen output. It seems doubtful that's the way Apple does it. More likely, the sensor signal goes to the processor and it uses the info as a flag to ignore the touchscreen output in software.
"
a sensor coupled to the user interface, the sensor to disable communication of the input signal to the processing section when the portable communication device is positioned in close proximity to a user, thereby, preventing inadvertent actuation of the touch sensitive input device."
It's vague enough to be interpreted different ways, perhaps. A "
sensor coupled to the user interface" could be interpreted as a software signal.
