I'm happy with that
"Using Voice Control to Unlock" is obvious and should have no protection whatsoever.
A specific method of listening to and parsing the voice command is a different matter.
Equally, a specific method of determining how a finger has touched the device (capacitive screen) could be a new thing.
Saying "The user touches the screen and slides along" is so obvious that not only was it being done before Apple filed, almost every touchscreen phone since the Neonode N1m has done it - iPhone, all HTC WinMobiles, etc.
If the US Patent Office doesn't switch from "approve everything, let the courts decide" to "examine everything like we're supposed to" soon, then there really is going to be an implosion.
