Appeal No. 1999-0918
Application No. 08/399,690
BACKGROUND
The invention is directed to a coextrusion binder composition including two
graft copolymers. The compositions are said to be useful as an adhesive layer in
multilayer composites. (Specification, p. 1). Claim 1 which is representative of the
invention is attached in an appendix to this decision.
As evidence of obviousness, the Examiner relies on the following references:
Akkapeddi et al. (Akkapeddi) 4,902,749 Feb. 20, 1990
van der Loos et al. (EP ‘512) EP 048512 Mar. 31, 1982
European Patent Application
The Examiner rejected claims 1 to 4, 6, 10, 11 and 17 to 19 under 35 U.S.C.
§ 103(a) over the combination of Akkapeddi and EP ‘512.1 (Answer, p. 3).
Rather than reiterate the respective positions advanced by the Examiner and
Appellants, we refer to the Examiner's Answer and to Appellants’ briefs for a
complete exposition thereof.
The Appellants submit that “the claims do not stand or fall together.” (Brief,
p. 4.) But in the “Argument” section of the brief, the Appellants merely recite the
invention covered by claims 6, 10, 11 and 17 to 19 and the statement the claims are
1 The rejection of claims 1 to 4 and 5 under 35 U.S.C. § 112, second paragraph, has been
withdrawn by the Examiner. (Answer, p. 2).
