Appeal No. 96-2675
Application No. 08/299,760
DECISION ON APPEAL
This is an appeal under 35 U.S.C. § 134 of the examiner’s
refusal to allow claims 1 through 24 and 26 through 30, which
are all of the claims on appeal.2
THE INVENTION
The invention is directed to a method of disposing
garments and other articles prepared from polyvinyl alcohol
having specific properties by dissolving the articles in warm
water at temperatures above about 37EC, the body temperature.
The polyvinyl alcohol has a degree of polymerization between
approximately 700 and 1500, a moisture content of
approximately 1.5% to 15% by weight, and contains 0.1% to 5.0%
by weight of an anti-blocking agent. It is produced from at
least approximately 98% saponified polyvinyl acetate. The
process further requires that the moisture content of the
polyvinyl alcohol polymer be reduced prior to melt extrusion
and be increased subsequent to melt extrusion.
2Claim 25 was canceled in an amendment dated March 30,
1994, paper No 6. Claims 31 through 59 were withdrawn from
further consideration by the examiner as directed to a non-
elected invention in accordance with 37 CFR § 1.142(b). See
the Final Rejection dated December 8, 1994, paper No. 12.
