Application No. 09/876,778
INTRODUCTION
Claims 1-7 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over U.S.
Patent 6,180,686 B1 issued to Kurth on January 30, 2001 (Kurth).1 Appellant states that the
claims stand or fall together (Brief, p. 3). We select claim 1 to represent the issues on appeal.
Claim 1 reads as follows:
1. An isocyanate-reactive component useful for the production of a rigid closed cell
polyurethane foam by a RIM process comprising:
a) from 0.5 to 30% by weight, based on total weight of isocyanate-reactive
component, of a polyol based on vegetable oil, fish oil or oil derived from animal
fat,
b) from 5 to 80% by weight, based on total weight of isocyanate-reactive component,
of an isocyanate-reactive material which is different from a) having a functionality
of at least 1 and a number average molecular weight of from 400 to 10,000,
c) a chain extender or a crosslinking agent,
d) a blowing agent, and
e) a catalyst.
We affirm and in so doing we adopt the Examiner’s well stated findings of fact and
conclusions of law as our own. We add the following for emphasis.
1The rejection of claims 1-7 under 35 U.S.C. § 102(b) as anticipated by WO 00/234,491 has been
withdrawn by the Examiner (Answer, p. 3).
