Appeal No. 2006-0623
Application No. 10/181,859
APPEALED SUBJECT MATTER
The appellant “elects to have claims 11-14, 16, 17, 19 and
20 treated as a single group.” See the Brief, page 4. The
appellant does not argue the separate patentability of the
individual claims on appeal. See the Brief in its entirety.
Thus, for purposes of this appeal, we select claim 11 from all
the claims on appeal and decide the propriety of the examiner’s
Section 103 rejection set forth in the Answer based on this claim
alone in accordance with 37 CFR § 41.37(c)(1)(vii)(2004). Claim
11 is reproduced below:
11. A method for improving the control of the soot induced
viscosity increase of diesel engine lubricant compositions
as they age[,] said compositions comprising a major amount
of a base stock and a minor amount of a dispersant by
incorporating into said diesel engine lubricant compositions
an effective amount of an antioxidant combination
characterized in that the antioxidant comprises an oil
soluble trinuclear organomolybdenum compound of the generic
formula:
Mo S -(Q) (I)3 x
wherein x is from 4 to 10, and Q is a core group, which may
be a ligand, and at least one other antioxidant compound
selected from an aminic compound.
