Appeal No. 97-0313
Application No. 08/346,083
7. A plastic optical fibre comprising a core formed of a
copolymer of 1H,1H-perfluorocyclohexylmethyl 2-fluoroacrylate.
13. An optical element comprising a homopolymer or copolymer
of 1H,1H-perfluorocyclohexylmethyl 2-fluoroacrylate.
The examiner relies upon the following references as
evidence of obviousness:
Yamamoto et al. (Yamamoto) 5,111,526 May 5, 1992
Savu et al. (Savu) 5,148,511 Sep. 15, 1992
McAllister et al. (McAllister) WO 93/03074 Feb. 18, 1993
(European patent application)
Bosc et al. (French '510) 2 623 510 May 26, 1989
(French patent application)
Appellants' claimed invention is directed to an optical
fiber or element comprising a homopolymer or copolymer of
1H,1H-perfluorocyclohexylmethyl 2-fluoroacrylate. According
to appellants, "the inventive fibers have excellent physical
properties when compared to other highly fluorinated polymer
materials which have been reported as low attenuation
materials" (page 7 of Brief).
Appealed claims 7-9 and 11-13 stand rejected under
35 U.S.C. § 103 as being unpatentable over McAllister in view
of French '510. Claim 13 stands rejected under 35 U.S.C.
§ 103 as being unpatentable over Savu in view of French '510
and Yamamoto.
