Response to Arguments
101 Rejection
Applicant argues the claims are not directed towards an abstract idea; however the examiner respectfully disagrees. The claims here are directed towards, an abstract idea falling into the abstract idea grouping of mathematical concepts, as Applicant’s specification details utilizing elastic wave theory to calculate a feature amount; see paragraphs [0085-0093]. The elastic wave theory used to calculate features is implemented on a generically claimed controller while the claim, as a whole, being information processing and not improving the way the controller operates. While the claimed invention aids performing calculations, these mathematical operations are performed by a general-purpose computer acting as a tool. Thus here, as in Electric Power, “the focus of the claims is not on … an improvement in computers as tools, but on certain independently abstract ideas that use computers as tools.” Elec. Power, 830 F.3d 1350, 2016 WL 4073318, at *4 [119 USPQ2d 1739].
Further, the claims, as an ordered combination, do not provide significantly more or integrate the abstract idea into a practical application, as a line sensor is well known and conventional in the art; as evidenced below by Keisuke (JP 2021067588A). The additional elements of an inspection object and elastic body surface of the inspection object merely link the abstract ideas to a technology, as neither the object or its surface is improved or bettered by the operation of the abstract idea. Therefore, the additional elements fail to provide significantly more or integrate the abstract idea into a practical application. o the abstract ideas.
Applicant further argues the claim is not directed towards the abstract idea because claim 1 is only based on or involves math, emphasizing there are no mathematical relationships, formulas or calculations. However, the only meaningful operation performed by the controller is calculating a feature using a mathematical operation, as supported by applicant’s specification; [0085-0093]. Therefore, the claim requires the performance of a mathematical operation to calculate the feature and the claim’s output exists only as the result of that mathematical operation; thereby supporting the conclusion the claim is directed towards an abstract idea.
Therefore, the examiner finds the claims not patent eligible.
102 Rejection
Applicant's arguments filed 12/8/2025 have been fully considered but they are not persuasive.
While applicant asserts Keisuke fails to teach “the above emphasized features”, the examiner would like to point below how Keisuke does teach those features. Keisuke teaches using a line sensor to sense the reflected light, i.e. a color line scan camera 14. Further, the acoustic wave as reflected is capable of being accompanied by an out-of-place displacement of the elastic body surface when an imperfection is found on the elastic body; as the imperfection creates a mode conversion and scattering of the wave. Therefore, the examiner finds Keisuke to read on the claimed invention.
Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claims 1-22 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more.
Claim 1 recites calculate a feature amount of a surface acoustic wave, based on direction information of a light ray that corresponds to gradient information of an elastic body surface of an inspection object that is obtained in a case where the surface acoustic wave is excited on the elastic body surface of the inspection object, the surface acoustic wave being accompanied by an out-of-plane displacement of the elastic body surface which falls into the abstract idea grouping of mathematical concepts. Applicant’s specification discloses utilizing elastic wave theory to calculate a feature amount; see paragraphs [0085-0093], thereby supporting the conclusion that the abstract idea falls into the abstract idea grouping of mathematical concepts.
This judicial exception is not integrated into a practical application because the generically claimed controller merely acts as a tool for performing the identified abstract; as neither the operation or result of the abstract idea improves the controller itself. MPEP 2106.05(a)
The additional element of a line sensor or an area sensor is considered to be merely performing an insignificant pre-solution activity of data gathering, as the sensor is solely collecting the needed data to perform the mathematical concepts. The sensor fails to integrate the abstract idea into a practical application, as neither the performance or result of the abstract idea improve the sensor or the data it gathers. MPEP 2106.05(a)
The additional element elastic body surface on an inspection object merely links the abstract idea to a field of use, as the neither the result or performance of the abstract idea improves the inspection object or its surface. Thereby, the elastic body surface on an inspection object fails to integrate the abstract idea into a practical application. MPEP 2106.05(h)
The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the additional element controller is merely performing the abstract idea while the result of the mathematical operation does not improve the controller or the generically link inspection object. The claimed sensor is not improved or bettered by the result or performance of the abstract idea. Therefore, the additional elements, alone or in combination, fail to amount to significantly more.
Claim 2 recites associate colors with the direction information of the light ray, and acquire the direction information of the light ray which falls into the abstract idea grouping of mental processes, as a human mind is capable of associating colors based on the results of the mathematical operation. Therefore, the claim fails to provide significantly more or integrate the abstract idea into a practical application.

Claim 5 further defines the abstract idea by reciting to estimate at least one of existence or non-existence of damage to an elastic body including the elastic body surface, a position of damage, and a size of damage, based on the gradient information of the elastic body surface which falls into the abstract idea grouping of mental concepts. Therefore, the further defines abstract idea fails to provide significantly more or integrate the abstract idea into a practical application; as the estimating fails to have a real-world effect to the additional element controller or inspection object.
Claim 6 further defines the abstract idea by reciting to calculate at least one of a density of liquid serving as an elastic body including the elastic body surface, a density of gas, gravitational force, surface tension, and a thickness of liquid, based on a relationship between a frequency and a wavelength of the surface acoustic wave that is to be acquired from the gradient information of the elastic body surface. Applicant’s specification discloses utilizing elastic wave theory to calculate the claimed elements; see paragraphs [0085-0093], thereby supporting the conclusion the abstract idea falls into the abstract idea grouping of mathematical concepts.
Claim 7 defines the additional element control by reciting “an exposure control portion configured to control exposure of an image sensor configured to acquire the gradient information of the elastic body surface; and a synchronous control portion configured to output an excitation start signal and an exposure start signal, the excitation start signal being a signal for starting excitation of the surface acoustic wave in a surface acoustic wave excitation portion configured to excite the surface acoustic wave on the elastic body surface, and the exposure start signal being a signal for starting exposure of the image sensor, with a predetermined time lag that is based on a propagation velocity of the surface acoustic wave”. The recited controller is merely acting as a tool controlling the additional element image sensor while respective control portions create control signals used to gather information from the additional element object. The generically claimed image sensor is merely acting as a tool for gathering data needed to perform the abstract idea. Further, neither the performance or result of the abstract idea improves the image sensor or data gathering steps themselves. Therefore, the claim fails to provide significantly more or integrating the abstract idea into a practical application. MPEP 2106.05(g)

Applicant’s specification discloses utilizing elastic wave theory to calculate a feature amount; see paragraphs [0085-0093], thereby supporting the conclusion the abstract idea falls into the abstract idea grouping of mathematical concepts.
This judicial exception is not integrated into a practical application because the step of optically acquiring gradient information of an elastic body surface of an inspection object being obtained in a case where the surface acoustic wave is excited on the elastic body surface of the inspection object reads as an insignificantly step data gathering; as the result or performance of the abstract idea does not improve the data gathering steps. MPEP 2106.05(a)
The additional element of a line sensor or an area sensor is considered to be merely performing an insignificant pre-solution activity of data gathering, as the sensor is solely collecting the needed data to perform the mathematical concepts.

Thereby, the elastic body surface on an inspection object fails to integrate the abstract idea into a practical application. MPEP 2106.05(h)
Th The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the additional element controller is merely performing the abstract idea while the result of the mathematical operation does not improve the controller or the generically link inspection object.

Sinha teaches a similar system the controller is configured to calculate a density of liquid serving as an elastic body including the elastic body surface (using collected frequencies of acoustic waves to calculate a density of a liquid, Col. 3 lines 30-42).

Kawasaki et al. teaches a similar apparatus that includes a synchronous control portion (17) configured to output an excitation start signal (for exciting vibration generation means 16) and an exposure start signal (i.e. an exposure signal starting light source 34), the excitation start signal (via 16) being a signal for starting excitation of the surface acoustic wave (by controlling vibration means 16) in a surface acoustic wave excitation portion (16) configured to excite the surface acoustic wave on an elastic body surface (24), and the exposure start signal (controlling 34) being a signal for starting exposure the sensor (42), with a predetermined time lag that is based on a propagation velocity of the surface acoustic wave (as during operation, the vibration signal starts prior to exposure).
It would have been obvious to one of ordinary skill in the art before the effective filing of the instant invention to modify the apparatus of Keisuke to include the surface wave excitation portion and corresponding control logic such that the timing allows for the collection of data from the surface of the object, as taught by Kawasaki et al. because Kawasaki et al. teaches such a modification improves the detection of unevenness in an object inspection process, as read in the Tech-Problem section of Kawasaki et al, thereby improving the detection accuracy of Keisuke.
With respect to claim 12, Keisuke teaches in Fig. 1 an information acquisition system of an elastic body (S), the information acquisition system (Fig. 1) comprising: the information acquisition apparatus of the elastic body according to rejected claim 8 (as it is part of the same system) but remains silent regarding a surface acoustic wave excitation portion configured to excite the surface acoustic wave on the elastic body surface.
Kawasaki et al. teaches a similar system that includes a surface acoustic wave excitation portion (12) configured to excite a surface acoustic wave on an elastic body surface (24).
It would have been obvious to one of ordinary skill in the art before the effective filing of the instant invention to modify the apparatus of Keisuke to include the surface wave excitation portion and corresponding control logic, as taught by Kawasaki et al. because Kawasaki et al. teaches such a modification improves the detection of unevenness in an object inspection process, as read in the Tech-Problem section of Kawasaki et al, thereby improving the detection accuracy of Keisuke.
With respect to claim 13, Keisuke as modified by Kawasaki et al. teaches in the information acquisition system wherein: the surface acoustic wave excitation portion (16 of Kawasaki et al.) comprises: a signal generator (i.e. a portion of 17) to be controlled by the controller (of Keisuke as modified), and a surface acoustic wave excitation element (16) configured to excite the surface acoustic wave (which generates the wave as seen in Fig. 2) based on a signal generated by the signal generator (i.e. the portion of 17 creating the vibrations), and the surface acoustic wave excitation element (16) is driven based on a signal (driving the vibrational means of Kawasaki et al.) repeating at a first frequency (i.e. a first frequency higher that a sampling frequency, as taught by Kawasaki et al. under the section <Micro Vibration generation means) that is output from the signal generator (i.e. the portion of 17) while being controlled by the modified controller (of Kawasaki et al.).
With respect to claim 14, Keisuke as modified by Kawasaki et al. teaches wherein: the surface acoustic wave excitation element (16 of Kawasaki et al.) comprises piezoelectric element (causing the vibrations), in a case where the elastic body is solid (i.e. as the object S is a solid sheet), and the surface acoustic wave excitation element (16) is configured to excite a Lamb wave on the inspection object (S) as the surface acoustic wave (as the acoustic wave excitation element creates a Lamb wave guided by the this sheet object S).
With respect to claim 16, Keisuke as modified by Kawasaki et al. teaches the surface acoustic wave excitation portion (16 of Kawasaki et al) comprises: a signal generator (i.e. a portion of the controller used to generate a signal to excite portion 16) to be controlled by the controller (as modified), and a surface acoustic wave excitation element (16 of Kawasaki et al.) configured to excite the surface acoustic wave based on a signal generated by the signal generator (of Kawasaki), and the surface acoustic wave excitation element (16 of Kawasaki et al.) is driven based on a signal obtained by amplitude-modulating a signal repeating at a first frequency f1 (i.e. a high frequency, as taught by Kawasaki) that is output from the signal generator (i.e. the portion of the controller used to generate the signal to excite portion 16) while being controlled by the controller (as modified), at a second frequency f2 (i.e. a low frequency) lower than the first frequency (of the signal).
With respect to claim 17, Keisuke as modified by Kawasaki et al. teaches all that is claimed in the above rejection but remains silent with respect to the first frequency f1 satisfies f1 ≥ 10 kHz, and the second frequency f2 satisfies f2 ≤ 1000 Hz.
It has been held that mere changes in size are not capable of patentably distinguishing an invention over the prior art, as set forth in MPEP § 2144.04(IV)(A).
In this instance, the person having ordinary skill in the art having a degree in engineering, has the capability to perform the engineering calculations necessary to ensure the frequency ranges fall within their intended behaviors.
It would have been obvious to a person having ordinary skill in the art prior to the effective filing date of the claimed invention to modify Kawasaki to have the first frequency f1 satisfy f1 ≥ 10 kHz, and the second frequency f2 satisfy f2 ≤ 1000 Hz, because one having ordinary skill in the art could easily determine the optimal frequencies for testing and measuring a specific object based on that object’s physical characteristics.
With respect to claim 18, Keisuke as modified by Kawasaki et al. teaches the modified information acquisition system wherein: the surface acoustic wave excitation portion (16 of Kawasaki et al.) is configured to excite the surface acoustic wave with an excitation wavelength changed with time (as during operation, the wavelength starts and finishes, thereby reading on “change with time” insofar as how “changed” is structurally defined), and the controller (as modified) is configured to detect internal damage based on the gradient information of each of the excitation wavelengths (as the system of Keisuke inspects the object for defects, which could include internal damage of object S).
With respect to claim 21, Keisuke teaches all that is claimed in the above rejection of claim 19 but remains silent regarding acquiring the gradient information comprises, adjusting: an excitation timing of the surface acoustic wave in a case of being excited on the elastic body surface; an exposure timing of an image sensor; and a light emission light onto the elastic body surface.
Kawasaki et al. teaches a similar method that includes adjusting: an excitation timing of the surface acoustic wave (by controlling element 16) in a case of being excited on an elastic body surface (24); an exposure timing of an image sensor (42); and a light emission light (via 34) onto the elastic body surface (as Kawasaki et al, based on respective control signals within the system, control elements, 16, 42 and 34 to perform the inspection of the object, adjusting the timing of the operation of these elements based on a start of the inspection).
It would have been obvious to one of ordinary skill in the art before the effective filing of the instant invention to modify the apparatus of Keisuke to include the step of adjusting the timing of controlling the various elements as taught by Kawasaki et al. because Kawasaki et al. teaches such a modification improves the detection of unevenness in an object inspection process, as read in the Tech-Problem section of Kawasaki et al, by ensuring all the components are operating according to one another.
Claim(s) 10, 11 and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Keisuke (JP 2021067588A) in view of Ohno (One-shot color mapping imaging system of light direction extracted from a surface BRDF).
With respect to claim 10, Keisuke teaches all that is claimed in the above rejection of claim 8 but remains silent regarding the gradient information acquisition portion comprises an image sensor configured to set an image capturing range with a circular region having at least a diameter λ or more, on the elastic body surface in a case where a wavelength of the surface acoustic wave that is obtained in a case where the surface acoustic wave is excited on the elastic body surface of the inspection object is denoted by λ, and a cycle is denoted by T, the number of pixels in an image captured within the image capturing range of the image sensor is n × m (n and m are integers equal to or larger than 3), and the controller is configured to control the image sensor, and acquire the gradient information of the elastic body as an image by setting an exposure time of the image sensor to a time shorter than T/2.
Ohno teaches a similar apparatus having an image sensor in Fig. 1 configured to set an image capturing range with a circular region (as seen in Fig. 1) having at least a diameter λ (as the circle inherently has a diameter), on an elastic body surface (material) in a case where a wavelength of an surface acoustic wave that is obtained in a case where the surface acoustic wave is excited on the elastic body surface of an inspection object (i.e. the surface of the material seen in Fig. 5) is denoted by λ, and a cycle is denoted by T, the number of pixels in an image captured within the image capturing range of the image sensor (as Ohno teaches a camera capturing the image, thereby having n x m pixels) is n × m (n and m are integers equal to or larger than 3), and a controller (as indirectly taught used to process the image collected) is configured to control the image sensor (image sensor seen in Fig. 1), and acquire the gradient information of the elastic body (i.e. material) as an image by setting an exposure time of the image sensor (Fig. 1) to a time shorter than T/2 (i.e. as indirectly taught, as during one shot structure light mapping, the exposure time must be less than the overall cycle time T, so as to ensure a strong signal to noise ratio without over exposure).
It would have been obvious to one of ordinary skill in the art before the effective filing of the instant invention to modify the apparatus of Keisuke with the structure of Ohno because Ohno teaches such a modification improves capturing microstructures on an object, as read in section 5. Conclusion of Ohno, thereby improving the defect detection sensitivity of Keisuke.
The method steps of claim 20 are performed during the operation of the rejected structure of claim 10.
With respect to claim 11, Keisuke teaches all that is claimed in the above rejection of claim 8 but remains silent regarding the apparatus comprising a light source portion configured to emit illumination light being parallel light, onto the elastic body surface, wherein: the gradient information acquisition portion comprises: a diaphragm including a first wavelength selection region; and an image sensor configured to capture an image of light passing through the first wavelength selection region at a deflection angle from the elastic body surface, and the controller is configured to calculate a deflection angle of a wavelength of the light based on a wavelength of light image-captured by the image sensor.
Ohno teaches a similar apparatus having a light source portion (LED) configured to emit illumination light being parallel light (after being split by the beam splitter), onto an elastic body surface (i.e. the material; Fig. 1), wherein: the gradient information acquisition portion comprises: a diaphragm (i.e. a multicolor filter acting in a manner that only allows select wavelengths to pass through) including a first wavelength selection region (as there are concentric circles defining the regions which allow different colors to pass; as read in section 2. One-shot light direction color mapping imaging system, page 3344, first paragraph); and an image sensor (seen in Fig. 1) configured to capture an image of light passing through the first wavelength selection region at a deflection angle from the elastic body surface (as read in section 2. One-shot light direction color mapping imaging system, page 3344, first paragraph), and a controller (as indirectly taught) is configured to calculate a deflection angle of a wavelength of the light (as discussed in Fig. 2 using equations 1-3) based on a wavelength of light image-captured by the image sensor (Fig. 1).
It would have been obvious to one of ordinary skill in the art before the effective filing of the instant invention to modify the apparatus of Keisuke with the structure of Ohno because Ohno teaches such a modification improves capturing microstructures on an object, as read in section 5. Conclusion of Ohno, thereby improving the defect detection sensitivity of Keisuke.
Claim(s) 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Keisuke (JP 2021067588A) in view of Kawasaki et al. (JP 2009025126A), as applied to claim 13, further in view of Lorraine et al. (5,760,904).
With respect to claim 15, Keisuke as modified teaches all that is claimed in the above rejection of claim 1, but remains silent regarding the surface acoustic wave excitation element comprises an airborne ultrasound element, in a case where the elastic body is liquid, and the surface acoustic wave excitation element is configured to excite at least either one of a capillary wave or a gravitational wave on the inspection object as the surface acoustic wave.
Lorraine et al. teaches a similar system having an airborne ultrasound element (12), in a case where the elastic body is liquid, and the surface acoustic wave excitation element is configured to excite at least either one of a capillary wave or a gravitational wave on the inspection object as the surface acoustic wave (as the inspection body does not further define the system over the prior art, as the element 12 is capable of being used to inspect any object, including liquid, and if its liquid the resulting wave would be a capillary wave).
It would have been obvious to one of ordinary skill in the art before the effective filing of the instant invention to modify the surface acoustic wave excitation element of Keisuke to be the airborne ultrasound element of Lorraine et al. because Lorraine et al. teaches such a modification provides a non-destructive wave to inspect various engineering structures or materials, Col. 1 lines 29-54, thereby increasing the versatility of Keisuke et al.
