DEFINITION

Classification: 5/636

For head or neck (e.g., pillow):

(under subclass 630) Subject matter in which the supporting surface sustains the users head or neck.

(1) Note. This subclass includes pillows, surgical supports for the head or neck and all other devices adapted to support the head or neck of a user in a supine or prone position.

(2) Note. The mere recitation of a "pillow", without further structural limitations, followed by composition(s) or filler material(s) comprising the pillow would not be enough for inclusion in this subclass. Such a device would go to where the filling composition does.
