fuel at an intake stroke. Column 3, lines 13-18, make clear that
the compressed lean mode (later lean mode of Fig. 1) is selected
in a region where both engine rotational speed and engine load
are low; whereas, as the engine rotational speed and engine load
increases therefrom, and an injection mode changeover is
required, the intake lean mode (earlier lean mode of Fig. 1), the
stoichiometric mode, and enriched mode are successively selected
in response to the magnitude of the increase. Kamura notes (col.
4, lines 13-22) that the relationship between the operation state
and the intake correction amount is set differently between the
compression stroke injection mode and the intake stroke injection
mode, and that owing to the configuration of the control, the
intake amount can be appropriately corrected for each of the
operational modes such as compression stroke injection mode and
intake injection stroke mode in the in-cylinder injection
internal combustion engine, thus allowing drivability to improve.
Aside from a bare assertion (brief, pages 6 and 7),
appellant has provided no reasoning as to why the examiner’s
determination regarding the correlation of the noted modes in
Kamura (Figs. 1 and 6) do not correspond to appellant’s claimed
fuel injection modes, particularly the examiner’s determination
