Am I missing something?
According to the text in the patent the screen at both sides of the notch are not part of the main screen area, will be always black and are only used to display information (e.g. clock , battery status, etc.). So you can free space in the main screen area! So it seems like the menu will be below the notch, as usual, and the notch will not interfere with the normal screen.
So I don't see the problem at all! and since the new MacBook Pros are supposed to use mini led, the background of the extended region can be made pitch black!
Seems like a good use of otherwise unused space, if is implemented as described in the patent.
