A recently uncovered patent application submitted in January 2009 by Microsoft is threatening to open up the old wounds we sustained when the Courier was canceled. The patent is for an animated page turn effect not unlike that seen in the iPad's iBooks and Kindle apps.
Part of the application reads, "The virtual page turn actively follows the page-turning gesture. 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." Sounds familiar, right? Neither Microsoft nor Apple can claim to have invented this, and it's unclear if this patent would have been granted.
If the application were granted, Microsoft would seemingly have no place to implement it. Add it to Windows 7 tablets? Maybe. More likely, this will just stand as another reminder of what the Courier could have been.
