The Verge: Apple's bounce-back patent receives 'final' rejection from US patent office
It's clear Samsung has copied a shit ton from Apple's iOS, iPhone, iPad, retail stores and everything in-between.
That being said, I don't think Apple, or any other company should own the patent on elasticity, virtual or otherwise.
As a web designer who started his career in 1999, I've seen seen many examples of (Flash) interfaces and websites that used bounce-back interactions in contexts similar to those in iOS years before the iPhone came to be.
