Samsung receives a patent for a phone that docks to power a tablet
With this design, Samsung is able to allow its smartphone to be more easily dockable with the receptacle on the back of its tablet/screen. The design makes it look like the slate is a stand-alone tablet and only the user will know that it is actually being powered by a smartphone.
Originally filled in the first quarter of 2012 in Korea and the following quarter in the U.S., Samsung was awarded patent D685,774 for "Terminal for wireless communication". Will Samsung challenge ASUS with a smartphone that can dock to a screen to power a tablet? It certainly seems that way. Considering the recent speculation that Samsung, like Apple, has lost its mojo, it could be that Samsung is hoping that something like this will boost sales.
