The invention relates to a wiping product such as facial tissue, bath
tissue and paper towels. (Br. 2; claim 21). Claim 1 is illustrative of the
invention and is reproduced below:
1. A wiping product comprising a non-woven fibrous sheet
containing a deliquescent material and a friction reduction compound.
The Examiner relies on the following prior art references to show
unpatentability:
Kennedy US 4,390,438 Jun. 28, 1983
Viazmensky US 5,009,747 Apr. 23, 1991

Kato in view of Nielsen and Kennedy.
2. Claim 23 under 35 U.S.C. § 103 as unpatentable over Kato in view
of Nielsen and Kennedy and further in view of Viazmensky.
BACKGROUND
The Examiner finds that Kato discloses the invention as claimed with
the exception of a polyethylene oxide friction reduction compound.
(Answer 3-4). The Examiner further finds that Nielson discloses the
addition of high molecular weight polyethylene oxide in the manufacture of
nonwoven/paper sheets to provide excellent slip characteristics and aid in
deterring the formation of clumps, tangles and bundles. (Answer 4). The
