Appeal No. 98-0194 Page 16
Application No. 08/132,940
that (1) the user control sets the level of energy desired by
the user, (2) the automatic control circuit includes a clock
which sets units of time of about a millisecond and an
integrator to calculate the amount of energy supplied from the
calculated power flow, and (3) the correlation circuit is a
comparator which is used to terminate the electrosurgical
generator's supply of energy to the active and return leads by
altering a drive circuit thereof when the amount of energy
calculated equals the reference signal sent from the user
control.
Based on our analysis and review of Bowers and claim 18,
it is our opinion that the only differences are the limitations
that (1) the user control sets the level of energy desired by
the user, (2) a clock and an integrator calculate the amount of
energy supplied from the calculated power flow, and (3) the
correlation circuit provides a feedback signal which alters the
supply of energy to the active and return leads when the amount
of energy calculated equals the reference signal sent from the
user control.
