I may get the patent on the smart cover, but I don't get how they could've been granted a patent on the flip page animation. The patent application is overly simplistic and clearly covers just the idea/design of the animation, rather than an actual implementation: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sec...

Furthermore, the web has been flooded with the exact same animation since the midst of 2004, all implemented in Flash. In the later years, these have also been implemented in pure HTML: https://github.com/blasten/turn.js

Given that Apples patent wasn't filed for until December 2011, I can't see why it wouldn't be dismissed on the grounds of prior art being publicly available.
