Secondly, nonobviousness cannot be established by attacking
the references individually when the rejection is predicated
upon a combination of prior art disclosures. See In re Merck
& Co. Inc., 800 F.2d 1091, 1097, 231 USPQ 375, 380 (Fed. Cir.
1986). Lastly, the combination of Janssen and Ager, as
modified above with respect to claim 3, would have formed at
least four barbs with at least two of the four barbs being cut
into a periphery of each head mounting section near the one
end in spaced apart relation from each other but in a common
plane at an angle to a longitudinal axis of the head mounting
section which would inherently provide support within the head
member 30 of Janssen on either side of the head mounting
section.
Dependent claim 6 adds to claim 5 the limitation that
the step of forming barbs includes cutting slits
into said handle sufficiently long to provide a firm
grip within the pad wherein the slits extend a first
distance equal to at least 3 percent of a second
distance through the handle; said second distance
being the distance through the handle in a direction
perpendicular to the longitudinal axis; said first
distance extending at an angle to the longitudinal
axis to form barbs that extend outwardly and
rearwardly whereby they are capable of catching
