Even if the patent leads nowhere, it's fun to see what a company's engineers are dreaming about. For instance, bendable screens once seemed like a silly idea, but Samsung eventually deployed them in its popular curved-screen Galaxy S6 Edge and S7 Edge products. Lenovo is also playing with the idea, and developed a smartphone you can bend around your wrist.

Unlike a split-screen phone or tablet à la Sony's crazy Tablet P, the device would work with a flexible OLED screen that also folds, either midway or further down. It looks an awful lot like the mockup phone Samsung showed off for its flexible Youm display back in 2013 (see the tacky video, below). A device like that would certainly be fun, but at this point Samsung's probably just making sure it doesn't mess up its next Galaxy S8 smartphone release.
