On January 24, the US Patent & Trademark Office published Apple's patent application titled Illuminated touch pad. Apple's patent generally relates to touch pads that provide visual feedback. More particularly, the present invention relates to illuminated touch pads that use light to provide feedback. Apple’s current patent would strongly suggest that the iPod classic could likely take another leap forward in the future with an advanced touch pad that displays unique illumination attributes. Apple’s current patent also covers the very touch pad features that debuted in their new MacBook Air earlier this month at MacWorld.
