Office Action

§102
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Scandola et al. (USPN 10,784,780). With respect to claim 1, a circuit (Fig. 1, further details of 104 disclosed in Fig. 2) comprising: a timer circuit (230 of Fig. 2) configurable to provide a timer signal circuits (output of 230) responsive to an output voltage of a power converter (responsive to VOUT+/V_out of converter 106 of Fig. due to VOUT+/V_out of being supplied to 228 with 212 and 220 wherein the output of 220 controls I_rmp supplied to 230 dependent on the VOUT+/V_out level), the timer circuit having a reset input (input to the switch that is connected in parallel to 231, i.e., switch input connected to ton_min); and control circuits (232 and 218) each having an input (input of 232 and input of 218) coupled to the timer circuit (inputs connected to output of 230/HOLD SIGNAL), at least one of the control circuits having an output coupled to the reset input (output of 232/ton_min coupled to the reset input of 230), wherein each of the control circuits is configurable to provide pulses (Ton-min pulses and pmw(t), see Fig. 5 when PFM operation of 104/204 is operative according to 116/216) and set a frequency of the pulses responsive to the timer signal (frequency is set according to the timer/hold signal, see Fig. 5). Allowable Subject Matter Claims 2-11 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Claims 12-27 are allowed. Response to Arguments Applicant’s arguments with respect to claim(s) 1 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
