I looked into turn.js and the licensing is beyond my understanding: The turn.js project is released under the BSD license and it's available on GitHub. This license doesn't include features of the 4th release. The part about 4th release seemingly links to a pdf but redirects to the same page. Going to github I find the following: https://github.com/blasten/turn.js/blob/master/license.txt """ turn.js 3rd release www.turnjs.com Copyright (c) 2012, Emmanuel Garcia All rights reserved.

""" Not exactly BSD as far as I see (is there a non-commercial BSD license subtype?) Furthermore I'm not the only one to wonder: https://github.com/blasten/turn.js/issues/491: Commercial licence turn.js And in the comments on that issue: "I'm waiting for about 2 years now for an announced / promised update. " Edit: added line breaks

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.
