Application 10/850,517
C. Bondoc
[7] Bondoc discloses a foam board comprising a polyisocyanurate foam
core faced on both surfaces with a material comprising glass and
cellulose fibers such as paper (Bondoc, abstract; col. 1, ll. 6-11; col. 2,
ll. 51-53; ex. 2; col. 6, ll. 5-10).
[8] The Examiner found that Bondoc did not disclose treating the facer
material with silane (Sub. Answer, 4).
D. Gill
[9] Gill discloses a fibrous glass mat said to be useful as a facer substrate
and which comprises a binder containing a wet proofing resin, i.e., a
water based silicone elastomer emulsion (Gill, col. 2, ll. 8-26; col. 4,
ll. 50-65; exs. 1-3).
E. Terae
[10] Terae discloses production of water based silicone emulsions from
organochlorosilanes, e.g., methyl dichlorosilane, trimethyl
chlorosilane, dimethyl dichlorosilane and methyl trichlorosilane
(Terae, col. 1, ll. 6-11; col. 3, ll. 3-7).
[11] According to Terae, its water based silicone emulsions are said to be
useful as water-repellant agents (Terae, col. 6, ll. 51-54).
[12] The Examiner cited Terae as evidence that methyl trichlorosilane is a
known silicone elastomer emulsion ingredient (Sub. Answer, 3-5).
Other findings of fact follow below.
III. Obviousness
A claimed invention is not patentable if its subject matter would have
been obvious to a person of ordinary skill in the art. 35 U.S.C. § 103(a);
