Application 10/352,542
claims 1-7, 10-29, 37-39, 41-44, 46-81, 87-88, 103-105, and 109-117, which
stand withdrawn from further consideration as directed to a non-elected
invention (Br. 2; Final Office Action dated Jul. 6, 2005, page 2). We have
jurisdiction pursuant to 35 U.S.C. § 6.
According to Appellants, the invention is directed to black powder
substitutes free of corrosive sulfur compounds, where the propellant
composition comprises a sulfur free deflagrating gas generating formulation
including oxidizing and reducing agents, and a first ignition aid of sodium
nitrobenzoate salt (Br. 3). Independent claim 30 and dependent claim 32 are
illustrative of the invention and are reproduced below:
30. A propellant composition comprising a sulfur free deflagrating
gas generating formulation including oxidizing and reducing agents
selected from the group consisting of carbon, sugars, nitrate salts,
perchlorate salts, benzoate salts, and mixtures thereof, and a first
ignition aid of sodium nitrobenzoate salt.
32. The propellant composition as in Claim 30, said sulfur free
deflagrating gas generating formulation including oxidizing and
reducing agents selected from the group consisting of carbon, lactose,
potassium nitrate, potassium perchlorate, sodium benzoate, and
mixtures thereof.
The Examiner has relied on the following prior art reference as
evidence of obviousness:
