Appeal No. 2002-1643 Page 4
Application No. 09/140,700
In rejecting claims under 35 U.S.C. § 103, the examiner bears the initial burden
of presenting a prima facie case of obviousness. See In re Rijckaert, 9 F.3d 1531,
1532, 28 USPQ2d 1955, 1956 (Fed. Cir. 1993). A prima facie case of obviousness is
established by presenting evidence that would have led one of ordinary skill in the art to
combine the relevant teachings of the references to arrive at the claimed invention.
See In re Fine, 837 F.2d 1071, 1074, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988) and In re
Lintner, 458 F.2d 1013, 1016, 173 USPQ 560, 562 (CCPA 1972).
Claims 1, 2, 5, 7, 11, 13, 15 and 16
Independent claims 1, 7 and 13 read as follows:
1. An industrial cleaning device comprising
a sheet material dispenser bag having at least one flexible sidewall,
said side-wall comprising at least two layers, one made of metal and the
other made of a flexible plastic material, said flexible plastic material forming the
outside of said side wall,
a strip of industrial cleaning sheets delineated from one another by lines
of weakness, said strip being contained within said bag, and an industrial
cleaning liquid absorbed into said sheets,
said bag having an outlet fixture forming a restricted outlet opening
through which said sheet material can be pulled with substantial resistance so as
to allow a sheet extending through said outlet opening to be withdrawn and torn
free from said strip when pulled out through said outlet opening,
in which said strip is formed into a roll and said roll is flattened and has a
hollow core hole from which said sheet material can be withdrawn longitudinally,
said hole being aligned so as to exit towards said outlet opening,
said industrial cleaning liquid containing a solvent selected from the group
consisting of acetone, isopropyl alcohol, methyl propyl keytone and methyl ethyl
keytone, naphtha, aromatic hydrocarbons and a mixture of two or more of the
foregoing.
