Office Action

§103
Final Rejection 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 . DETAILED ACTION The amendment filed 05/04/2026 has been entered. Claims 1-14 remain pending in the application. Response to Arguments Applicant’s amendments to the claims are sufficient to overcome the rejection under 35 U.S.C. 112(b) of claims 1-14. Accordingly, the rejection has been withdrawn. Applicant' s arguments with respect to claim(s) 1 and all subsequent dependent claims have been considered but are moot in view of the references cited in the most current rejection. Claim Rejections - 35 USC § 103 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 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, 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1-4 and 13 are rejected under 35 U.S.C. 103 as being unpatentable over Saksela (US 20190261108 A1) in view of Kang (KR 101270100 B1, all citations provided from machine translation attached). Regarding Claim 1 Saksela teaches an acoustic camera (10) comprising: acoustic sensors (32, 41, 45) detecting sound wave or ultrasonic wave and a sensor board (Figs.6A-6C) on which the acoustic sensors (32, 41, 45) are mounted and a housing (15) located at the rear of the sensor board and forming a built-in space. (Paragraphs 35-36, 59-61, Claim 1, Figs.1-2, 6A-6C) Saksela also teaches a main control unit (31) receiving and processing acoustic signals generated from the acoustic sensors (computer 31 changes the acoustic signal intensity information), wherein the main control unit (31) is located in the built-in space (Fig.2), and wherein the sensor board is located outside the housing (Figs.6A-6C). (Paragraphs 42-41, 59-61, Figs.1-2, 6A-6C) Saksela also teaches a connector connecting the sensor board and the housing (the LCD driver board can include additional components, and this board can be fixed in the device by connecting it to the inner surface of the housing from its sides). (Paragraph 59) Saksela does not explicitly teach a molding connector and wherein the molding connector includes an epoxy molding structure configured to prevent explosive residues from leaking out. Kang teaches a molding connector (30, 50) and wherein the molding connector includes an epoxy molding structure (epoxy molding material) configured to prevent explosive residues from leaking out (the epoxy molding material 45 in the event of an electrical fire or explosion due to sparks or overheating inside the distribution panel 40, This prevents the flame from spreading outside) (prevents the epoxy molding material from escaping from the body by the explosion pressure in the event of electrical fire and explosion accident due to spark or overheating). (Page.2, lines 16-18, 38-40, Page.6, line 3, Figs.4, 7) It would have been obvious to one having ordinary skill in the art before the effective filling date to have modified Saksela to incorporate a molding connector and wherein the molding connector includes an epoxy molding structure configured to prevent explosive residues from leaking out as taught by Kang in order to prevent the spread of secondary fires and explosions through the cable in the event of an accident Regarding Claim 2, Saksela teaches a barrier circuit unit installed between the acoustic sensors and the main control unit, and wherein the barrier circuit unit transmits the acoustic signals generated by the acoustic sensors to the main control unit, wherein the barrier circuit unit suppresses an increase in current or voltage on an acoustic signal transmission line transmitting the acoustic signals generated by the acoustic sensors, and wherein the barrier circuit unit and the main control unit are located in the built-in space of the housing. (Paragraphs 59-61, 74, Figs. 1-2, 6A-6C) Regarding Claim 3, Saksela teaches a data collecting unit between the sensor board and the main control unit, and wherein the barrier circuit unit is provided between the sensor board and the data collecting unit. (Claim 1, Figs.1-4b, 6A-6C) Regarding Claim 4, Saksela teaches a photographing means taking an image of a scene toward which the sensor board is facing. (Paragraph 41, Figs.1-4b, 6A-6C) Regarding Claim 13, Saksela teaches a front body provided with sound wave inflow holes that guide the sound wave or the ultrasonic wave to reach the acoustic sensor. (Paragraphs 74, Figs.1-2, 6A-6C) Claim(s) 5, 9 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over Saksela in view of Kang and Huseynov (US 9482592 B2). Regarding Claim 5, Saksela does not explicitly teach wherein the barrier circuit unit comprises a resistor to suppress current rise, a Zener diode to suppress voltage rise, a fuse to block overcurrent on an acoustic signal transmission line that transmits the acoustic signal generated by the acoustic sensor or a clock signal transmission line that transmits a clock signal. Huseynov teaches wherein the barrier circuit unit comprises a resistor to suppress current rise, a Zener diode to suppress voltage rise, a fuse to block overcurrent on an acoustic signal transmission line that transmits the acoustic signal generated by the acoustic sensor or a clock signal transmission line that transmits a clock signal. (Col.8, lines 47-64, Fig.5) It would have been obvious to one having ordinary skill in the art before the effective filling date to have modified Saksela to incorporate wherein the barrier circuit unit comprises a resistor to suppress current rise, a Zener diode to suppress voltage rise, a fuse to block overcurrent on an acoustic signal transmission line that transmits the acoustic signal generated by the acoustic sensor or a clock signal transmission line that transmits a clock signal as taught by Huseynov in order to avoid electrical damage to be transmitted to the microphone thus protecting the circuit from electrical failure.

(Paragraphs 54-55) Saksela in view of Kang, Huseynov and Shimizu discloses the claimed invention except for a distance between signal lines is 1.5 mm or more and a separation distance is 1.5 mm or more. It would have been obvious to one having ordinary skill in the art at the time the invention was filled to incorporate a distance between signal lines is 1.5 mm or more and a separation distance is 1.5 mm or more, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. It would have been obvious to one having ordinary skill in the art before the effective filling date to have modified Saksela to incorporate wherein a distance between the acoustic signal transmission line and the clock signal transmission line is a distance, and wherein a separation distance between one acoustic signal common transmission line and another acoustic signal common transmission line is a distance as taught by Shimizu in order to prevent collision of data and ensure stable transmission of audio signals. Claim(s) 11 is rejected under 35 U.S.C. 103 as being unpatentable over Saksela in view of Kang, Huseynov and McCartan (US 6270460 B1). Regarding Claim 11, Saksela does not explicitly teach wherein a separation distance between one fuse and another fuse among the plurality of fuses is 10 mm or more. McCartan teaches wherein a separation distance between one fuse and another fuse among the plurality of fuses is a distance. (Claim 4, Fig.2) Saksela in view of Kang, Huseynov and McCartan discloses the claimed invention except for a distance 10 mm or more. It would have been obvious to one having ordinary skill in the art at the time the invention was filled to incorporate a distance 10 mm or more, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. It would have been obvious to one having ordinary skill in the art before the effective filling date to have modified Saksela to incorporate wherein the separation distance between one fuse and another fuse among the plurality of fuses is a distance as taught by McCartan in order to avoid electrical damage to be transmitted thus protecting the circuit from electrical failure. Claim 14 is rejected under 35 U.S.C. 103 as being unpatentable over Saksela in view of Kang, Huseynov and Lin (CN 205864606 U, all citations provided from machine translation attached) Regarding Claim 14, Saksela teaches further comprising a photographing means, wherein the photographing means is located behind the tempered glass or in the built-in space of the housing. (Paragraphs 74, 43, Figs.1-2, 6A-6C) Saksela does not explicitly teach wherein the front partition has an imaging hole and wherein the imaging hole is closed with transparent tempered glass. Lin teaches wherein the front partition has an imaging hole and wherein the imaging hole is closed with transparent tempered glass.
