Office Action

§102
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 . Response to Arguments Applicant's arguments filed 9/17/2026 have been fully considered but they are not persuasive. Applicant argued that the prior art JP3769718 has not been shown to disclose the newly amended recitation “and wherein the first output end of the each differential inverting amplifier and the first input end of the next adjacent differential inverting amplifier have opposite polarities, and the second output end of the each differential inverting amplifier and the second input end of the next adjacent differential inverting amplifier have opposite polarities” because ¶[0007] of JP3769718 states “The positive phase output of each stage is input to the next phase positive phase input, and the negative phase output of each stage is input to the next phase negative phase input”. This argument is partially correct due to the typographical error in that section of the paragraph [0007] because JP3769718 further discloses corrected description as shown in Figure 1 of JP3769718. The ¶[0007] of JP3769718 further states “The positive phase output of each stage is input to the negative phase input of the first stage differential amplifier 12a”. Figure 1 of JP3769718 shows a ring oscillator 12 and each stage is a differential amplifier having + input and - input and - output and + output (not shown but implied because of intrinsic property of differential amplifiers) as later corrected in the paragraph. Claim Rejections - 35 USC § 102 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claim(s) 1-20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by JP3769718 (cited by the applicant, in IDS filed on 3/25/2026, Extended European Search Report) for reasons of record. The newly amended recitation is also shown in Figure 1. Conclusion THIS ACTION IS MADE FINAL. 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.
