Appeal No. 1998-2551 Page 12
Application No. 08/787,624
Claim 48 reads as follows:
An abrasive fabric comprising: a substrate having
abrasive particles connected to one side thereof and a
loop pile fabric adhered to the other side thereof, said
loop pile fabric comprising: a plurality of yarns, each
comprised of a core and effect yarn, laying adjacent to
and spaced from one another, said effect yarns having a
plurality of loops projecting therefrom to act as
receivers for the hook of a hook and loop interconnection
and an adhesive applied to said yarns including the loops
of said effect yarns and bridging adjacent yarns such
that said adhesive bridges adjacent yarns to maintain
said yarns spaced from one another and/or adheres loops
of spaced yarns to loops of adjacent yarns.
Based on our analysis and review of Hong and claim 48, it
is our opinion that the only difference is the limitation
concerning the details of the loop pile fabric (i.e., lines 4-
13 of claim 48 above).
With regard to this difference, the examiner determined
(answer, p. 4) that
Altman does not set forth the use of core and effect
yarns as the strip 16 therein. However, Altman's
statement that any loopy knotted thread-like material is
useful as the strip 16 renders obvious the substitution
thereof with the polyester core and effect yarns of
Eschenbach, motivated by the expectation of being able to
control the "loopyness" of the strip material.
As such, it would have been obvious to adhere (as
set forth by Hong et al.) the modified strip material of
Altman to the abrasive pad of Hong et al., motivated by
the inexpensive nature of the construction of the Altman
