Here, the examiner admits, “Read does not explicitly
disclose ... that the clock signal with the means to align is
phase aligned.” (Second Supplemental Examiner’s Answer at 3.)
This is an understatement. The reference merely teaches
synchronizing clocks with data. Specifically, “timing islands
provide levels at which the clocks are synchronized with the
data, in order to prevent skewing between the timing used
by various subsystems.” Col. 2, ll. 8-11.
The examiner fails to allege, let alone show, that
Cisneros remedies the defects of Read. He instead relies on
Murakami to “disclose that the clock signal with the means to
align is phase aligned ....” (Second Supplemental Examiner’s
Answer at 3.) Although the latter reference teaches phase-
aligning, it does not teach individually phase-aligning data
bits transmitted on lines of a bus with respect to a clock
signal transmitted along with the data on another line of the
