count'. Instead, Yamada argues that the drawing itself, fails to
provide an explanation of how any of the circuit diagrams or
handwritten notations in the drawing relate to the invention of
the count (Paper 28 at 12).
It is not apparent why such an explanation is necessary.
The "first circuit diagram" of the drawing shows the elements of
the count. The "first circuit diagram" shows a ring oscillator
comprisingan odd number (13) of inverters (labeled LPWR OSC
INV). The oscillator is connected to a charge pump.
Specifi.cally the output of the last inverter (annotated as "N")
is connected to a charge pump (annotated as "Z"). The output of
the last inverter is also connected to an input of the first
inverter. The output of each inverter X is connected to the
input B of a succeeding inverter. A secondary input A of each
inverter is connected to the output X of a 7t' proceeding
inverter. (Findings 36-40).
A picture can be worth a thousand words. The "first circuit
diagram" by itself, without further explanation, describes an
embodiment within the scope of the count, Yamada has failed to
sufficiently demonstrate why one having ordinary skill in the art
would need an explanation to understand what the drawing shows.
ý During oral argument, counsel for Yamada indicated that
the "first circuit diagramý' did show the elements and connections
recited in the count.
