Foss Patents is reporting that the U.S. Patent and Trademark Office has tentatively invalidated Apple's bounce scroll — sometimes referred to as "rubber banding" — patent possibly affecting the recent ruling in the Apple vs Samsung trial.
The patent in question concerns the bounce scroll feature in iOS: scroll too far, and whatever you're looking at bounces back into position. A Monday court filing from Samsung reveals that the USPTO has invalidated all of Apple's claims to it, US Patent No. 7,469,381. The patent has been rejected on prior art considerations — one concerning a "controlling content display" by AOL/Luigi Lira published on October 2nd 2003 and another a "continuous scrolling list with acceleration".
The USPTO claims "no inventive step" was found between the prior art and Apple's patent — so it's now up to the company to prove to the patent office or the appeals court that the IP was new. As for Samsung, it already found a workaround to avoid infringing the overscroll bounce patent — but it would likely reintroduce the feature if Apple can't back up its IP.
