One thing is for sure about any tech company. You can never have too many ideas or patents. We've heard for some time now rumors about the possibility of RIM make a BlackBerry laptop. Perhaps with this latest patent it may just happen. But from the abstract of this patent, it would happen in the form of a laptop-tablet hybrid. The details describe how the keyboard and the screen would conform to each other.
Here is the full abstract from the patent:
An electronic device having a concealed keyboard includes a first housing, a second housing rotatably coupled to the first housing, and a concealment cover coupled to a rear of the first housing. The first housing has a coupling edge and two sides that are substantially perpendicular to the coupling edge of the first housing. The second housing has a coupling edge and two sides that are substantially perpendicular to the coupling edge of the second housing. A receiving portion is formed on a rear surface of the first housing and is configured to receive the second housing. When the second housing is in the receiving portion, each respective side of the first housing and the second housing are co-terminal with one another. The concealment cover is exteriorly positioned with respect to the second housing when the second housing is in the receiving portion.
