A quick primer, digital skeuomorphic design elements are when the interface or the icon is designed such that it looks like the physical world object that it is designed to digitally replicate. For example, the bookshelf in Ibook, is digital skeuomorphic design. There is no reason that a digital container of book files needs to look like a bookshelf; other than to relate to you, the user, what is the purpose of the digital program. Additionally, buttons with dropped shadows, or clever isometric representations of objects within the icon space, are all examples of digital skeuomorphic design.
However, with the advent of flat design across the three major mobile development platforms, things like icons designed to look like bookcases is going to be a thing of the past. Flat design, like its "Modernism" architectural equivalent is premised of reducing the ostentation ornamentation. In the same way that neo-Gothic architecture like this gave way to boxy simplicity of like this, so too does flat design trend to simple geometric forms and a studied lack of ostentation and ornamentation.
Part of this change has been led by a difference in attitudes regarding the purpose of the GUI in the first place. Digital skeuomorphic designs were originally used to help people with no inherent knowledge of the inner workings of computers to easily map real world actions to digital ones. A digital file was made to look like a physical office file. A digital delete function was made to look like a trash can, etc. Now, with at least two generations of American consumers raised on digital entertainment, there is less of a need to visually explain the functions of each icon. It is simply enough, in most instances, to state its function and designate an area for the user to interact with that function.

GUIs, flat or not, can be protected by design patents. In 1996, the USPTO created guidelines for the protection of GUIs based on its decision in Ex Parte Strijland. GUI design or surface ornamentation is protectable as long as it is shown to be novel, not obvious, and not functional. The claimed design may be presented as a line drawing or a digital image. Color and grayscale are allowed to be presented in the same GUI application, but line drawings and digital images are not. Animated designs are also patentable in the United States, and must show a minimum of two views of the animation.
This is all a long winded intro into the point. Of the recent victories that Apple has achieved against Samsung, Apple succeeded in proving that Samsung had copied a design patented GUI (seen at left). As you will note, this Apple design is chock full of skeuomorphic elements. This includes not only the icons themselves, but their placement, the shape of the icons, their slightly beveled appearance etc.
However, by moving to a flat design paradigm, Apple and its competitors are moving into a field whose sole purpose is to simplify the display elements, not add ornamentation. As noted above, design patents mush have a non-functional use, and must be directly related to the ornamentation. If flat design takes hold, it will be increasingly difficult for designers to obtain protection for flat designs as they essentially become functional identifiers for computer tasks. As a result, we are going to see a lot of convergent design elements that people will accuse other people of stealing, but no one will be able to obtain a patent on.
As a result, it is preferable to augment your GUI design patent strategy with a screen shot copyright strategy. This way, if it is an instance of blatant copying, you are still protected by an enforceable IP right.
