The patent includes two different ways to incorporate an inking space. First, as shown in the image above, a laptop could have a dedicated inking space next to the trackpad. Second, as shown in the image below, the inking space could be housed on the back of a detachable keyboard. This second option would provide more space to use for inking but could affect a laptop's durability.

As with all patents, these designs might never be used in a product. They do illustrate that Microsoft is trying to think of new ways to maximize the utility of devices.
