Appeal No. 2007-0301
Application No. 10/277,435
13. In a method for the production of polyurethane elastomers comprising
the mixing and curing of a polyurethane prepolymer with methylene bis-
orthochloroaniline, the improvement that comprises blending a stabilizing
amount of a hindered amine light stabilizer with the methylene bis-
orthochloroaniline.
The claims stand rejected under 35 U.S.C. § 112, first paragraph, on
the grounds that “the specification does not reasonably provide enablement
for compositions comprising methylene bis-orthochloroaniline and hindered
amine light stabilizers other than (1,2,2,6,6-pentamethyl-4-
piperidinyl)sebacate” (Answer 2). We reverse.1
DISCUSSION
Claims 1, 7, and 13 stand rejected under 35 U.S.C. § 112, first
paragraph, “because the specification, while being enabling for stabilized
compositions comprising methylene bis-orthochloroaniline and (1,2,2,6,6-
pentamethyl-4-piperidinyl)sebacate, does not reasonably provide enablement
for compositions comprising methylene bis-orthochloroaniline and other
hindered amine light stabilizers. The specification does not enable any
person skilled in the art to which it pertains, or with which it is most nearly
connected, to make and use the invention commensurate in scope with these
claims” (Answer 3).
