Micron Lands Broad "Slide To Unlock" Patent
Zordak writes "Micron has recently landed U.S. Patent 8,352,745, which claims priority back to a February 2000 application---well before Apple's 2004 slide-to-unlock application. While claim construction is a highly technical art, the claims here are (for once) almost as broad as they sound, and may cover the bulk of touch screen smart phones on the market today. Dennis Crouch's Patently-O has a discussion."
The USPTO is holding roundtables with software developers to ask for suggestions. If anyone can add to what's there already, I've some suggestions on this wiki:

(But remember, the patent office has only a small role in patent policy. Most substantial changes will have to come from Congress or the Supreme Court.)

I'm not a patent expert, although I did once watch a very informative video about how patents work. This makes me eminently qualified on the subject by slashdot standards.
Looking at the independent claims, it looks like at least the lock screen as implemented by Samsung (starting at the unlock button, drag a certain distance in any direction to unlock) and possibly other Android phones out there is safe from this patent.
Since the system on Samsung phones works no matter which direction you drag, it looks like the "slide to unlock" implementation in Samsung phones is clear.
However, I think this patent may very well be applicable to the "pattern lock" of android phones.
