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.
Claims 1, 3-10, 12-16, 18, 21-25, 27 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Utagawa (WO 2008120826).
Regarding Claim 1, Utagawa discloses the following limitations:
An interference-resistant microwave detection method, comprising the following steps: (Utagawa – [pg. 8 para. 2] In the microwave / millimeter wave sensor devices according to the fourth to ninth embodiments described above, the bias method different from the fixed bias method employed in the microwave / millimeter wave sensor device according to the first embodiment is applied. [pg. 11 para. 3] the substrate 31 on which the frequency selective circuit pattern is patterned functions as a frequency selective filtering unit that selectively filters radio waves having a required frequency, thereby suppressing radiation of unnecessary signals.
(A) emitting a detection beam corresponding to a local oscillator signal to form a corresponding detection space; (Utagawa – [pg. 20 para. 1] The present invention applies a microwave / millimeter wave band signal to a measurement object, receives a reflected wave from the measurement object, and detects information on the measurement object (for example, motion detection, speed detection, presence detection, position detection) The present invention relates to a microwave / millimeter wave sensor device. [pg. 20 para. 2] Conventional microwave / millimeter wave sensor devices transmit transistor functions such as transistor oscillator circuits or GUNN diode oscillation circuits, diode mixer circuits, antennas, couplers, distributors, transmission / reception circulators, etc. They are connected by a track. Such a conventional microwave / millimeter wave sensor device generally uses an oscillation signal of an oscillation circuit as a transmission RF signal, and extracts a part of the oscillation signal by a distribution circuit and uses it as a local signal for a mixer circuit. This is a homodyne sensor type microwave / millimeter wave sensor device that converts a received RF signal into an IF signal by causing this mixer to function as a homodyne downconverter.)
(B) receiving an echo formed by the detection beam which is reflected by a detected object in the detection space and generating a feedback signal; (Utagawa – [pg. 20 para. 1], [pg. 20 para. 2])
(C) outputting a Doppler intermediate frequency signal in a differential signal form, wherein the Doppler intermediate frequency signal corresponds to the frequency/phase difference between the local oscillator signal and the feedback signal; and (Utagawa – [pg. 20 para. 1], [pg. 20 para. 2], [pg. 26 para. 3] The received IF signal voltage is a Doppler beat signal when the object to be measured is moving, and a zero-beat DC signal in which a standing wave is detected when the object to be measured is stationary.)
(D) outputting the Doppler intermediate frequency signal which has been processed by frequency selective cancellation, wherein a common-mode interference, generated by a wireless communication signal in an environment interference signal superimposed on the feedback signal, is capable of being eliminated in the Doppler intermediate frequency signal, (Utagawa – [pg. 11 para. 3], [pg. 26 para. 3])
wherein the wireless communication signal has any frequency relationship selected from a group consisting of same frequency, adjacent frequency and harmonic frequency with a frequency of the local oscillator signal, (Utagawa – [pg. 11 para. 3])
a frequency selective cancellation circuit is used to perform the selective frequency cancellation on the Doppler intermediate frequency signal in the differential form output in the step (C), wherein the frequency selective cancellation circuit comprises a first equivalent resistance, a second equivalent resistance, and an equivalent capacitor, (Utagawa – [Fig. 13], [pg. 8 para. 3-4] FIG. 13 is a circuit configuration diagram of the microwave / millimeter wave sensor device according to the tenth embodiment. The radiating oscillator substrate S10 is supplied with DC power only from the DC power supply DC2 and is taken out from the radiating oscillator substrate S10. The detected signal (IF signal) is analyzed and processed by the signal analysis processing unit P. The microwave / millimeter wave sensor device according to the present embodiment includes a capacitor 7c in parallel with a resistor 7 serving as an IF band load means in the voltage division (series feedback) self-bias circuit structure employed in the above-described eighth embodiment. A connected drain load bypass type voltage division type self-bias circuit structure is employed. In addition, about the structure same as the microwave and millimeter wave sensor apparatus shown in each embodiment mentioned above, the same code | symbol is attached | subjected and description is abbreviate | omitted. In the radiation type oscillator substrate S10, by appropriately setting the capacitance value of the capacitor 7c, the IF signal amplification function can have a frequency characteristic of low-frequency amplification (high-frequency attenuation). Attenuates the signal and is effective in improving sensor characteristics. For example, when the value of the resistor 7 is 100 [Ω] and the IF signal is a signal in the band of DC to 1 kHz, if the value of the capacitor 7c is 1.5 [μF], the cutoff frequency fc = 1 / ( 2π × 1.5 × 10−6 × 100) ≈1 kHz high-frequency attenuation characteristics, and noise and signals in unnecessary bands of 1 kHz or more can be attenuated. [pg. 26 para. 7] the effective value of the load resistance Reff is a combined resistance value obtained by connecting the resistors 7 and ro in parallel.)

In addition, since radiation without the GND conductor surface 255 is performed in both directions of the conductor patch plate, if this double-sided radiation is used, the sensor functions as a sensor that detects a wider angle range than when the GND conductor surface 255 is present. Can be made. A fifth modification shown in FIGS. 28A and 28B includes a GND conductor surface 256 and a through hole 35 connecting the GND conductor surface 256 and the GND conductor surface 255 around the substantially fan-shaped conductor patches 4 and 4. This is an example in which a signal is transmitted through the dielectric substrate 259 to prevent leakage from the end of the substrate and loss. If the size and shape of the GND conductor surface 256 are appropriately set, the signal energy corresponding to the loss can be used as the original radiation energy instead of the signal being transmitted through the dielectric substrate 259.)

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.
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.

Response to Arguments
Applicant’s arguments, see Page 13, filed 12/09/2025, with respect to the rejection under 35 U.S.C. § 112(b) have been fully considered and are persuasive. The rejection under 35 U.S.C. § 112(b) has been withdrawn.
Applicant’s arguments, see Page 13-19, filed 12/09/2025, with respect to the rejection under 35 U.S.C. § 102(a)(1) and 35 U.S.C. § 103 have been fully considered and are not persuasive. Applicant argues that “Utagawa neither teaches nor suggests differential Doppler IF signal processing”. The examiner disagrees, “differential Doppler IF signal processing” is a well understood term that is synonymous with a “beat frequency” which inherently measures the difference between two signals using a mixer. Utagawa further elaborates that the product of the mixer is downconverted into an intermediate frequency that represents a “Doppler beat signal” to explicitly show that the voltage generated at the mixer due to the difference in signals is a measure of the Doppler effect. Applicant argues that “Utagawa neither teaches nor suggests elimination of common-mode communication-signal interference having specified frequency relationships to the local oscillator”. The examiner disagrees, Utagawa clearly teaches “a frequency selective filtering unit that selectively filters radio waves having a required frequency, thereby suppressing radiation of unnecessary signals”. The applicant seems to argue for a narrower interpretation of a “wireless communication signal” than what is presented in the claims and the instant specification. Applicant argues that “Utagawa neither teaches nor suggests the frequency-selective cancellation circuit having the specific differential-topology structure”. The examiner disagrees, the limitations do not seem to be more specific than the provided citations. The term “equivalent” in regards to “capacitor” or “resistor” refer to a measurement that can be a hypothetical combination of parallel circuitry causing the claims to be broad. This allows for an interpretation that does not require specific resistor or capacitor placement as any associated connections. The provided diagrams and citations meet map to the claims when considering the limiting terminology. Applicant argues that “wherein the first equivalent resistance and the second equivalent resistance are set to have a resistance value of approximately 39kΩ within an error range of 25%, and the equivalent capacitor is set to have a capacitance of approximately 47nF in an error range of 25%”. The examiner disagrees, Utagawa clearly teaches “a capacitor 7c in parallel with a resistor 7 serving as an IF band load” and “appropriately setting the capacitance value of the capacitor 7c, the IF signal amplification function can have a frequency characteristic of low-frequency amplification (high-frequency attenuation)” and continues to give an example of resistance and capacitance to facilitate for the selected attenuation characteristics based on a received signal. The claimed resistance and capacitance fit to the provided citation due to having the ability to adjust to these parameters.
Applicant’s arguments, see Page 19-20, filed 12/09/2025, with respect to the rejection under 35 U.S.C. § 102(a)(1) and 35 U.S.C. § 102 103 have been fully considered and are not persuasive. Applicant argues that the dependent claims are allowable due to the dependency on the independent claims. The examiner disagrees due to the above-mentioned rejections.
Applicant's remaining arguments amount to a general allegation that the claims define a patentable invention without specifically pointing out how the language of the claims is understandable and distinguishable from other inventions.
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 extension fee 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 date of this final action.
