video signals," Hunt has not been shown to satisfy the claim
feature of multiplexing information signals into the non-useful
or dead (i.e., dark) video data signals.
In the supplemental answer from the bottom of page 1 to the
top of page 2, the examiner stated:
Concerning the "dark" video data, the examiner
maintains that these data are not a direct result of
the invention, but a phenomenon that occurs due to
uneven illumination inherent in most illumination
systems, especially stroboscopic illumination system.
(Emphasis in original.)
What exactly does "a direct result of the invention" mean is
unclear. But whether or not a feature is a direct result of the
invention, it still has to be met if it is a part of the claimed
invention and cannot be ignored. It appears that the examiner is
saying that every scanned line of a product surface will include
"dark" video pixels or data signals. But the claimed invention
requires more than that. The claimed invention calls for a
specific manner of using those "dark" pixels or video data
signals, i.e., the multiplexing of information signals into the
place of the "dark" video signals to create a sequential data
stream for transmission. It is this more particular feature
which is not disclosed or reasonably suggested by the prior art
as applied by the examiner.
