Response to Arguments
2. In the argument submitted on 11/24/2025, Applicant argues that At pages 2 and 3 of the Office Action, the Office asserted an interpretation of Katoch in which line 260 of Katoch is considered to correspond to a recited "signal node" and circuit 410 is considered to correspond to a recited "delay stage," referring to FIG. 4 of Katoch. However, the Office did not assert an interpretation of Yang consistent with "a delay stage coupled directly connected to the signal node and configured to output a first booster signal responsive to the first control signal" as recited in claim 1 and "outputting, from a delay stage of the booster circuit, a booster signal in response to the first control signal received at the delay stage directly from the signal node" as recited in claim 17.
Applicant's arguments filed have been fully reconsidered but they are not persuasive because the delay stage can be also mapped to I1, 410 and I2 instead of only 410. Thus, the prior art Katoch teach with "a delay stage coupled directly connected to the signal node and configured to output a first booster signal responsive to the first control signal" as recited in claim 1 and "outputting, from a delay stage of the booster circuit, a booster signal in response to the first control signal received at the delay stage directly from the signal node" as recited in claim 17. In additional, a new ground of rejection of claim 1 and claim 17 are made in view of newly submitted reference Telecoo ( US 20030025532)
