Sony Ericsson’s annoying auto-keylock patent

Have you ever spent hours looking for the auto-keypad-locking feature on your Nokia phone? Wondering why you have to manually engage the lock function on a Blackberry? It turns out that Sony-Ericsson has a patent on the “activation and automatic inactivation of keys on a mobile telephone terminal keypad.” Please Sony and Ericsson, for the love of god, and the eradication of pocket-dialing, give this patent up.
