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 .
Priority
Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed in parent Application No. 2022-153602, filed on 09/27/2022.
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 07/25/2024 and 09/26/2023. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 4-6 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
In Claim 4, line 4, the recitation of “a maximum frequency of the frequency band” it is not clear since the frequency band is not clearly defined and the frequency band is lack of antecedent basis. Further clarification is needed.
In Claim 5, line 7, the recitation of “a second frequency band other than the first frequency band included in the frequency band” it is not clear since the in claim 5 which cited first frequency band and second frequency band, however the frequency band is not clearly defined since the frequency band appears lack of antecedent basis. Further clarification is needed.
In Claim 6, line 9, similarly, the recitation of “the frequency band” is also unclear, thus Claim 6 is rejected as well in the same manner as discussed in claim 5 above.
It is noted that Claim 1, line 19, which states “a preset frequency band”.
Allowable Subject Matter
Claims 1-3 & 7-8 are allowed.
Upon conclusion of a comprehensive search of the pertinent prior art, the Office indicates that the claims are allowable.
The prior art when taken alone, or, in combination, cannot be construed as reasonably teaching or suggesting all of the elements of the claimed invention as arranged, disposed, or provided in the manner as claimed by the Applicant. Added primarily for emphasis, the claim recitations “ a test signal generation circuit configured to modulate a test signal in which a frequency is changed in a preset frequency band to generate a third modulated signal and a fourth modulated signal in a second operation mode; and a peak frequency detection circuit configured to measure a potential difference between the first output terminal and the second output terminal” and “ detect a frequency range including a peak frequency that is the frequency of the test signal at which an impedance of the sound reproduction device peaks in the second operation mode” and “a plurality of inverter circuits each having an output terminal coupled to the first output terminal, the second amplifier circuit includes a plurality of inverter circuits” in claim 1 is not found in the prior art of record.
Claims 2-3 and 7-8 are allowable as being dependent of claim 1.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
Claims 4-6 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Reference (US 7262658 B2) to Ramaswamy et al. discloses in Fig. 2 a Class-D amplifier system comprising, output stages 90 & 118 and a pair of integrators 80 and 82 and wherein dual integrator loop filter 80, 82 drives a comparator 84 and the comparator 84 compares a first integrator filter signal 85 with the output 86 of the loop filter to provide a corresponding quantized output signal at a comparator output 88 and the quantized output signal at 88 is a PWM and Col. 2, lines 20-24, an audio amplifier system.
