As to Carman, while this reference teaches a single point
attachment of the free end of the screen to the window casing
or sash, it is not done so in the context of providing for
pivoting or tilting movement of the free end of the screen.
Instead, the single point contact of Carman is in the context
of providing for a latching structure. To this end, Carman
provides a catch F that is rigidly attached to a U-shaped
screen guard E which in turn is attached to the free end of
the screen. The catch F cooperates with a spring I having a
rod-shaped portion and, when the catch is engaged with the
rod-shaped portion of the spring in the latched condition, the
screen guard is held tightly against the window sill or sash,
thus preventing pivoting or tilting of the free end of the
screen in the manner claimed. Absent the appellant's own
teachings, we can think of no cogent reason why one of
ordinary skill in this art would have singled out the concept
of a single point contact from the latch of Carman and
incorporated it into the structure of Golkowski in such a
manner so as to arrive at the claimed invention. The examiner
