Appeal No. 95-5097
Application No. 08/072,807
halogenated copolymers of isomonoolefins and alkylstyrene
(Id.). Finally, the examiner notes that the “open” language
of the claims does not preclude the additional monomer
disclosed by Yu.3
Appellants assert that “[t]o be anticipatory a reference
must clearly and unequivocally disclose the claimed
composition without any need for picking, choosing and
combining various parts of its disclosure” (Brief, page 6).
Appellants argue that there is no explicit description
directed to the halogenated copolymer component of Yu (Brief,
pages 9 and 11). Regarding the “open” language of the claimed
composition, appellants argue that Yu’s grafted polymer is not
identical to the halogen-containing copolymer from which Yu
made the grafted polymer (Brief, page 13). Appellants submit
that Yu requires a grafted polymer and the claimed term
“halogenated copolymer” does not literally or otherwise
require the presence of a grafted group (Id.).
3Yu teaches that the polyamide and polyolefin are blended
with a grafted polymer derived from reacting Reactant A with
Reactant B, where Reactant A is the halogenated or non-
halogenated copolymer of an isomonoolefin and alkylstyrene and
Reactant B is an unsaturated organic compound such as maleic
anhydride (see column 1, lines 30-45; column 2, line 20-column
9, line 63).
