Appeal No. 96-2593
Application No. 08/119,075
6-11 and 14-20, all the claims remaining in the present
application. Claims 1 and 20 are illustrative:
1. A thermoplastic polyester lamination structure
comprising 1) at least one layer of a thermoplastic polyester
(A) prepared from i) an acid component mainly comprising an
aromatic dicarboxylic acid and a glycol component mainly
comprising an aliphatic glycol and ii) 2-type aluminum oxide
particles (B) and 2) at least one layer of another
thermoplastic polyester laminated to said layer of a
thermoplastic polyester (A).
20. A thermoplastic polyester lamination structure
comprising at least one layer of a thermoplastic polyester (A)
prepared from i) an acid component mainly comprising an
aromatic dicarboxylic acid and a glycol component mainly
comprising an aliphatic glycol and (ii) 2-type aluminum oxide
particles (B), said particles having an acicular or platy
shape.
The examiner relies upon the following reference as
evidence of obviousness:
Murooka et al. (Murooka) 5,252,388 Oct. 12, 1993
(filed Dec. 13, 1991)
Appealed claims 1-4, 6-11 and 14-20 stand rejected under
35 U.S.C. § 103 as being unpatentable over Murooka.
Upon careful consideration of the opposing arguments
presented on appeal, we find that the examiner has failed to
establish a prima facie case of obviousness for the claimed
subject matter. Accordingly, we will not sustain the
examiner's rejection.
