While SAP has made a big push into mobile software and device management with the acquisition of Sybase and a series of apps, it hasn't made overt moves into the devices market. But this could change down the road, judging from a recently published patent application submitted by SAP. The application, which was published late last month, describes a "foldable information worker mobile device" which can be reconfigured to work as a tablet, laptop, phone, e-reader, and other device types as an employee moves through a series of tasks.
