As mentioned earlier, Microsoftâ€™s Windows Phone 7 UI seems to have caught the imagination of many, likely because its pretty unique. So unique in fact that Microsoft has applied for a patent for the design.
The September 2008 patent is summarized as such:
A panoramic graphical user interface includes a contiguous background and a collection of mixed-media content objects. The contiguous background includes one or more space-orientating graphical elements and is sized to fit within a first dimension of a display and to extend beyond a second dimension of the display. The collection of mixed-media content objects are anchored over the contiguous background. The collection of mixed-media content objects are arranged to fit within the first dimension of the display and arranged to extend beyond the second dimension of the display.
I guess that means it wont be showing up on an iPhone any time soon
