Appeal 2007-2195
Application 10/172,166
1. A generant composition comprising:
between about 25 and about 60 composition weight percent non-azide
nitrogen-containing gas generating fuel;
between about 10 and about 55 composition weight percent metal
ammine nitrate oxidizer;
between about 2 and about 10 composition weight percent metal oxide
burn rate enhancing and slag formation additive; and
between about 1 and about 20 composition weight percent potassium
perchlorate gas generant additive.
34. The gas generant composition of claim 1 free of ammonium
nitrate.
The Examiner relies upon the following references as evidence of
obviousness:
Mendenhall US 6,077,372 Jun. 20, 2000
Taylor US 6,083,331 Jul. 4, 2000
Appellants’ claimed invention is directed to a gas generant
composition comprising a non-azide nitrogen-containing gas generating fuel,
a metal ammine nitrate oxidizer, a metal oxide, and potassium perchlorate
gas as a generant additive. Claims 34-36 recite that the composition is free
of ammonium nitrate.
Appealed claims 34-36 stand rejected under 35 U.S.C. § 112, 1st ¶,
description requirement. Claims 1-15, 17-20, and 31-33 stand rejected under
35 U.S.C. § 103(a) as being unpatentable over Taylor. Also, claims 1-15,
