Appeal No. 95-1209
Application No. 07/842,480
Yamada et al. (Yamada) 5,174,924 Dec. 29, 1992
(filed June 4, 1990)
Hawley’s Condensed Chemical Dictionary, 935 (11th ed., New
York, Van Nostrand Reinhold, 1987) (Hawley’s).
REJECTIONS
(1) Claims 1, 3, 4 and 11 are rejected under 35 U.S.C. § 112,
second paragraph, as being indefinite.
(2) Claims 1, 3, 4 and 11 are rejected under 35 U.S.C.
§ 103(a) as being unpatentable over the combined disclosures
of Miyake.
For the reasons set forth post we shall not sustain these
rejections (although appellants have argued the separate
patentability of claim 11, in view of our disposition of this
appeal, we need not consider claim 11 separately.)
DISCUSSION
The examiner has rejected the claims as being indefinite
in view of the claim 1 phrase “copolymer of said polyfluoro-
alkylsiloxane.” The examiner maintains it is not clear how a
compound that is not silanol terminated can be copolymerized.
