Specifically, the porous insulating material covering
layer 2 having necessary thickness is formed around the
periphery of the inner conductor 1, for example, by such
means as (a) a tape-shaped porous insulating material such as
foamed plastic is wound spirally around the periphery of the
inner conductor 1 along its lengthwise . . . .
A reference is available for all that it discloses and
suggests, even unpreferred embodiments. See In re Lamberti, 545
F.2d 747, 750, 192 USPQ 278, 280 (CCPA 1976); and In re Mills, 470
F.2d 649, 651, 176 USPQ 196, 198 (CCPA 1972). It would have been
obvious to one of ordinary skill in the art at the time the
invention was made to wind the insulator about the conductor such
that it was in contact with the conductor. Additionally, JP ‘321,
the primary reference, makes no use of an adhesive resin.
Accordingly, we conclude that claim 7 would have been obvious
to one of ordinary skill in the art at the time the invention was
made.
II. The Rejection of Claims 2-4, 6, and 9 Under 35 U.S.C. § 103(a)
Claims 2-4, 6 and 9 stand rejected under 35 U.S.C. § 103(a)
as being unpatentable over JP ‘321 in view of JP ‘622, further in
view of Leef.
Claim 2 reads as follows:
2. A coaxial cable as claimed in claim 1, wherein said metal
layer has a thickness of at least 0.2 μm.
