Appeal No. 94-2267
Application No. 07/896,799
1. An improved organic polymer alloy containing:
a) at least one polyaryl ether ketone having a reduced
viscosity of from 0.2 to 3 dl/g and
b) at least one amorphous polyaryl ester having a reduced
viscosity of from 0.1 to 2 dl/g,
wherein the improvement comprises that the polyaryl ether
ketone is amorphous, components a) and b) are homogeneously mixed
and the organic polymer alloy is transparent.
As evidence of unpatentability of the claimed subject
matter, the examiner relies on the following references.
Robeson et al. (Robeson) 5,011,894 Apr. 30, 1991
(Filed June 29, 1984)
Isayev 5,006,402 Apr. 9, 1991

For the purposes of interpreting the term “amorphous” in the
appealed claims, the examiner relies on the following references:
Lakshmanan et al. (Lakshmanan) 4,857,594 Aug. 15, 1989
Gallucci et al. (Gallucci) 4,749,754 Jun. 7, 1988
Ames 4,159,287 Jun. 26, 1979
The appealed claims stand rejected under 35 U.S.C. § 102(e)
as anticipated by or, in the alternative, under 35 U.S.C. § 103
as obvious over the Robeson reference. We reverse.
The appealed subject matter is directed to an organic
polymer alloy containing homogeneously mixed at least one
particular amorphous polyaryl ether ketone and at least one
particular amorphous polyaryl ester. See claim 1. The organic
