Federal Circuit -- CW ZUMBIEL V. KAPPOS

Adding a finger flap to a carton was a sufficiently obvious move, regardless of how the carton was intended to be carried, especially as there's no particular reason that the carton should be carried in that way.

Adding flap dispenser to carton similarly obvious.

Preamble to claim appropriately considered.

Dissent: It's a box with holes in it at obviously logical points.
