specificity” to establish anticipation. Atofina v. Great Lakes Chem. Corp.,
441 F.3d 991, 999, 78 USPQ2d 1417, 1423 (Fed. Cir. 2006)).
The issue presented for review with respect to this rejection is: Does
the Lin reference have a disclosure that anticipates the claimed subject
matter? The issue turns on whether Lin describes a method for operating an
internal combustion engine comprising a gasoline composition comprising a
monoamide-containing polyether alcohol compound. We answer this
question in the affirmative.
The Examiner finds that Lin describes a gasoline composition
comprising a monoamide-containing polyether alcohol compound of the
formula R, C(O)-NR2R3 wherein R1, R2, and R3 are each independently
selected from H, C1 -C100 hydrocarbyl (alkyl or alkenyl) polyoxyalkylene
alcohol of 2-200 carbon atoms with the proviso that one of R1 -R3 is
polyoxyalkylene (Lin 3, ll. 5-22). Lin teaches that the compounds reduce
intake valve deposits, control octane requirement increases and reduce
octane requirement (Lin 3, ll. 22-26). Lin teaches that the deposits on the
intake valves results in overall poor drivability, including stumbles during
acceleration (Lin 3, ll. 9-13). Therefore, the Examiner correctly determines
that the fuel composition of Lin necessarily improves acceleration
performance by removal or reduction of intake valve deposits. The
compounds contain up to 50 moles of the alkylene oxide wherein the
alkylene oxide may be ethylene, propylene or butylene oxide
