proved. If the fact is well known, then it should be a
simple matter for the Examiner to provide a reference.
Thus, the Examiner has not persuaded us that Appellants'
arguments as to limitations (1) and (2) are in error.
The Examiner states that Kaiser does not limit its base
to any specific material. As we understand the rejection,
the Examiner concludes that it would have been obvious to
use common materials such as aluminum or copper to provide
heat dissipation, where "said materials are known to oxidize
and would therefore provide a native oxide or anodization
layer" (EA4, discussing the material limitations in
claim 9).
Kaiser has a gold plated copper base. Thus, it does
not have an "in situ anodization dielectric layer." The
microstrip transmission line 72 (comprising a dielectric
substrate 75 having a ground plane conductor 77 on the
bottom surface and a strip conductor 80 (circuit trace) on
the top surface, i.e., a double sided circuit board) is
"affixed" (col. 3, line 9) to the base. The dielectric
substrate is not an "in situ anodization dielectric layer"
because it is not an "in situ" layer nor an anodized
