Appeal No. 1997-2977
Application No. 08/431,688
to arrive at the subject matter of appealed claim 1. We
answer this question in the positive.
As candidly admitted by the appellants, Babel teaches a
substrate which is identical to that recited in appealed claim
1, except for the fluoropolymer topcoat. Specifically, Babel
teaches an article comprising an anodized aluminum surface and
an inorganic coating of white paint (column 2, lines 63-65).
According to Babel, “a high emittance low absorptance coating”
on the aluminum surface is provided (column 2, line 65 to
column 3, line 2). The anodized aluminum and the inorganic
white paint, as described in Babel, fall within the scope of
the “non-ferrous metal substrate” and the “porous inorganic
white paint thermal control coating,” as recited in appealed
claim 1 (column 3, lines 34-43 and column 4, lines 8-25;
specification, page 9, line 24 to page 10, line 12, and page
11, line 10 to page 12, line 4). Babel not only teaches that
the coated substrates are useful for spacecraft applications
(abstract; column 5, lines 58-68), but also suggests
terrestrial applications, including “indoor or outdoor
architectural or domestic application[s]” (column 4, lines 54-
59).
