Will Apple sue Google with “slide to unlock patent”

Apple recently received patent for their iOS start screen feature "slide to unlock". You might have seen the iPhone keynote by Steve Jobs. He explained the unlock feature is a swipe to the width of the screen and it is to avoid accidentally unlocking the phone.

Android also has the slide feature to unlock the start screen as default option. They also have the custom lock screen pattern through Settings --> Location and  security settings --> Use visible pattern.

Apple’s is aggressive in protecting their Intellectual Property or blocking Android manufacturers (esp. Samsung) from selling their devices. (Stories of Apple suing Samsung in Dutch, Australia etc and Samsung suing Apple in Germany) :)

Steve Jobs view of Android is “I will spend my last dying breath if I need to, and I will spend every penny of Apple's $40 billion in the bank, to right this wrong. I'm going to destroy Android, because it's a stolen product. I'm willing to go thermonuclear war on this.” as per Walter Issacson.

Do you think, Apple will sue Google (Android) using this patent???
And what if Google patents the notification feature and sue Apple back???

Lets see only time will reveal us the news... :)
