Microsoft Claims Patent For E-Book 'Page Turn' Animation

Microsoft has filed a patent with the US Patent and Trademark Office, relating to the virtual 'page-turning' technology used by many e-book readers, tech news website The Register has reported.

Microsoft's application for patent number 20100175018 indicates that the company is looking to patent the page-turning animation that occurs when a user makes the appropriate hand gesture on the touch screen of an e-book reader device.

The filing reads: “The virtual page turn curls a lifted portion of the page to progressively reveal a back side of the page while progressively revealing a front side of a subsequent page.”

If Microsoft is awarded the patent, it's likely to spark a dispute with Apple, whose e-book reader for its iPad device uses just such a feature. Other e-book readers that incorporate virtual page-turning features are Amazon's Kindle app for the iPhone and iPad, Aldiko for Android and Stanza for iPhone. monitors all leading technology stories and rounds them up to help you save time hunting them down.
