EXAMINER’S COMMENTS To facilitate processing of the internet communication authorization or withdrawal of authorization, the Office strongly encourages use of Form PTO/SB/439, available at www.uspto.gov/PatentForms. The form may be filed via the USPTO patent electronic filing system using the document description Internet Communications Authorized to facilitate processing. If applicant authorizes Internet communications, USPTO employees may respond to email and initiate communications with applicants via email. Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(4) because reference character “134” has been used to designate both an armature and a first back volume. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, “an armature having a movable portion connected to the diaphragm” and “a terminal board comprising an electrical interface located within the housing” recited in Claims 1 and 13, “the diaphragm comprising an S-shaped frame supporting a paddle connected to the armature” recited in Claim 6, must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 103 5. 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 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. 6. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. 7. Claims 1-4, 7 and 10 are rejected under 35 U.S.C. 103 as being unpatentable over Zhang et al. (hereinafter Zhang) US-PG-PUB No. 2021/0204064 in view of Badillo et al. (Hereinafter Badillo) US-PG-PUB No. 2021/0204079 and further in view of Granicki US-PG-PUB No. 2019/0273989. Regarding claim 1, Zhang teaches A receiver-in-canal (RIC) hearing device component (a receiver-in-canal (RIC) device…..Para. [0016], Lines 3-8) comprising: a balanced armature receiver (Fig. 8 shows an acoustic receiver 800) comprising: a housing (Fig. 8 shows a receiver housing 802) containing a diaphragm (Fig. 8 shows a diaphragm 804) that separates an interior of the housing (i.e. receiver housing 802) into a back volume (Fig. 8 shows a back volume 808) and a front volume (Fig. 8 shows a front volume 806) acoustically coupled to a sound port (Fig. 8 shows an acoustic output 810) of the housing (i.e. receiver housing 802) (Para. [0027], Lines 1-9), the housing (i.e. receiver housing 802) constitutes an exterior of the RIC hearing device component (i.e. acoustic receiver 800) as shown in Fig. 8; a multicoil motor (Fig. 8 shows a receiver motor assembly 814) located in the housing (i.e. receiver housing 802) and comprising an armature (Fig. 8 shows an armature 812 (also known as a reed)) having a movable portion (Fig. 8 shows a paddle 816) connected to the diaphragm (i.e. diaphragm 804) as shown in Fig. 8; a terminal board (Fig. 8 shows a terminal board 700), the multicoil motor (i.e. receiver motor assembly 814 includes coils 200, 202) electrically connected to contacts of the terminal board (i.e. terminal board 700)….Para. [0026], Lines 1-4; a capacitor component integrated with the electrical interface and electrically connected to contacts of the electrical interface (the reactive circuit element is mounted directly on the terminal board…..The reactive circuit element includes a capacitor……Para.

One of ordinary skill in the art could have modify the balanced armature receiver of Zhang with the electrical interface located within the housing and the electrical cable assembly comprising the first end portion connected to the housing and the electrical connector on the second end portion of the electrical cable assembly as taught by Badillo. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the balanced armature receiver of Zhang with the electrical interface located within the housing and the electrical cable assembly comprising the first end portion connected to the housing and the electrical connector on the second end portion of the electrical cable assembly as taught by Badillo. The motivation is to improve output in balanced armature receivers by protecting the electrical interface placing the electrical interface within the housing and using the electrical cable assembly enables electrical signals to be transmitted between the housing and the electrical connector. Zhang does not teach electrical connections of the multicoil motor and the capacitor component to the electrical interface configured to change an electrical impedance of the balanced armature receiver based on a frequency of an electrical signal applied to the multicoil motor. Granicki teach a capacitor component integrated with the electrical interface and electrically connected to contacts of the electrical interface (a capacitor to the intermediate point of the first balanced armature driver and the end point which is connected to the positive signal cable of the cabling…Para. [0018]), electrical connections of the multicoil motor and the capacitor component to the electrical interface configured to change an electrical impedance of the balanced armature receiver based on a frequency of an electrical signal applied to the multicoil motor (an impedance and phase curve of the driver when cabled conventionally. It appears clearly that the impedance of the driver varies greatly depending on the frequency of the input signal….Para. [0060]). It would have been obvious to one of the ordinary skills in the art before the effective filing date of the application to use the impedance control taught by Granicki as impedance control in the balanced armature receiver taught by the combination of Zhang and Badillo. The motivation to do so would have been to improve the quality of the acoustic output from the receiver. Regarding claim 2, the combination of Zhang, Badillo and Granicki teach all the features with respect to claim 1 as outlined above.
