Appeal No. 2002-2273 2
Application No. 09/363,688
The appellants’ invention relates to a gas fumigation system. Claim 11, the sole
independent claim on appeal, reads as follows:
11. A system for gas fumigating at least one region, comprising:
a phosphine source;
an inert substance source;
a mixer fluidly coupled to the phosphine source and the inert
substance source to form a gaseous mixture including phosphine flowing
from the phosphine source and inert substance flowing from the inert
substance source, the gaseous mixture passing from the mixer to the
region during gas fumigation; and
a flow controller controlling at least one of flow of the phosphine
from the phosphine source to the mixer and flow of the inert substance
from the inert substance source to the mixer so that the gaseous mixture
is non-flammable in air.
The sole prior art reference of record relied upon by the examiner in rejecting the
appealed claims is:
Schellhaas et al. (Schellhaas) 5,260,022 Nov. 9, 1993
Claims 11-16, 44-46, 50 and 51 stand rejected under 35 U.S.C. § 102(b) as
being anticipated by Schellhaas.
Claims 47-49 stand rejected under 35 U.S.C. § 103(a) as being unpatentable
over Schellhaas.
