Office Action

§102
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 . Response to Amendment The Amendment filed February 12th, 2026 has been entered. Claims 1, 5, 8-10 have been amended. Claims 1,5-6 and 8-14 are now pending in the application, with claim 14 withdrawn. The previous 35 U.S.C. 112(a) rejection of claim 3, as well as, the previous 35 U.S.C. 112(b) rejections of claims 1, 2-3 and 10 are withdrawn in light of Applicant's amendment and Applicant cancelling claims 2-3. Response to Arguments Applicant's arguments filed 02/12/2026 have been fully considered but they are not persuasive. In response to arguments that Horiuchi et al. (US 20240078694 A1) does not disclose the three-dimensional structure model of the subject that is constructed from… captured images that are acquired while a relative positional relationship between the subject and the image sensor is changed, examiner respectfully disagrees. As detailed below, a 3D reconstruction portion, i.e. 3D model, reads out an image set data captured by imaging portion and generates relative dimension information [0052]. The image set is a plurality of time-series images acquired by endoscope which are near-point images and far-point images, i.e. acquired at different positions, therefore the examiner is interpreting this as the images are acquired at different positions so the positional relationship between the subject and image sensor must be changing [0011, 0092]. Moreover, the 3D information M is constructed from the image set and the relative distance data ds(i), i.e. pseudodistance data, is calculated from the 3D information M [0079-0082]. The applicant makes the argument that the claim language is intended to define a specific 3D technology known as Structure-from-Motion (SfM), whereas, the prior art defines a different type of technology, however, the invention as claimed does not define these parameters, therefore, the examiner is interpreting the claim language with the broadest reasonable interpretation. The examiner maintains the rejection under 35 U.S.C. 102(a)(2) with Horiuchi et al. (US 20240078694 A1), however, the examiner has updated the rejection below to provide more clarification. Applicant’s arguments, see Remarks, filed 02/12/2026, with respect to Oka et al. (US 20110074950 A1, hereinafter Oka) have been fully considered and are persuasive. The 35 U.S.C. 102(a)(1) rejection of Claims 1-2, 4-6 has been withdrawn. Applicant’s arguments, see Remarks, filed 02/12/2026, with respect to Oka et al. (US 20110074950 A1, hereinafter Oka) in view of Yoshioka et al. (WO 2021131238 A1, hereinafter Yoshioka, using US 20220330850 A1 as an English Equivalent) have been fully considered and are persuasive. The 35 U.S.C. 103 rejection of Claim 3 has been withdrawn. Examiner’s Comments The present rejection(s) reference specific passages from cited prior art. However, Applicant is advised that the rejections are based on the entirety of each cited prior art. That is, each cited prior art reference “must be considered in its entirety”. Therefore, Applicant is advised to review all portions of the cited prior art if traversing a rejection based on the cited prior art. Claim Rejections - 35 USC § 102 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1,5-6 and 8-13 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Horiuchi et al. (US 20240078694 A1, hereinafter Horiuchi). Regarding Claim 1, Horiuchi discloses A medical endoscope system (endoscope system 100; FIG. 1) comprising: an endoscope (endoscope 2) including an image sensor (imaging portion 6) that acquires a captured image by imaging an inside of a body cavity as a subject (par. 8 discloses in the case of an endoscope with which the interior of a living body is observed); and one or more processors (endoscope processor 3) configured to: generate pseudodistance data (relative distance ds(i)) by estimating a distance to the subject for a plurality of locations (plurality of corresponding regions Q (i)) within an imaging range (par. 34 discloses plurality of image plane phases, i.e. image range) of the image sensor using the captured image (par. 66 discloses a corresponding region is a region in an image, relative distance is a distance from a camera position, which is the point of view, to a corresponding region in the direction along the optical axis in the coordinate system of the relative 3D information, i.e. distance information estimated from a 3D model), wherein the pseudodistance data is generated using a three-dimensional structure model of the subject that is constructed from a plurality of frames of the captured images that are acquired while a relative positional relationship between the subject and the image sensor is changed (par. 52 discloses a 3D reconstruction portion, i.e. 3D model, reads out image set data captured by imaging portion and generates relative dimension information, FIG. 4A, par. 11 discloses reconstructing is done by employing a plurality of time-series images acquired by endoscope, par. 92 discloses image set consists of plurality of near-point images and far-point images, i.e. images acquired from different positions of the image sensor relative to the subject, par. 79 discloses 3D information M is constructed from the image set, par. 82 discloses relative distances ds(i) calculated from 3D information M); acquire actual measurement distance data (imaging-subject distance dt(i)) by measuring the distance to the subject for at least one location within the imaging range (par. 58 discloses imaging-subject distance is the actual distance from the objective lens to the imaging subject in the direction along the optical axis, imaging-subject-distance calculating portion calculates the imaging-subject distance of each of the measurement regions), wherein the actual measurement distance data is measured using the captured image obtained by irradiating the subject with auxiliary measurement light of which an optical axis is inclined with respect to an imaging optical axis of the image sensor (par. 6 discloses it is necessary to provide the endoscope with a laser module that radiates the laser light for taking measurements, and it is not possible to measure the dimensions of an imaging subject otherwise, in the context of this invention); calculate a scale factor (scale information/ coefficient α) by dividing the actual measurement distance data by the pseudodistance data of the same location (par. 67 discloses equation (1) which calculates scale information coefficient by performing mathematical operation, i.e. division, of the absolute distance and relative distance, par. 104 discloses design alterations or the like within a range that does not depart from the scope of the present invention are also encompassed); and correct the pseudodistance data of a different location by multiplying the pseudodistance data of the different location by the calculated scale factor (par. 69 discloses equation (2) shows how the scale converting portion of the processor calculates the absolute dimensions of the other regions by multiplying the relative dimensions ds of the other regions by the coefficient). Regarding Claim 5, Horiuchi discloses The medical endoscope system according to claim 1, wherein the auxiliary measurement light is laser light (par. 6 discloses laser light component). Regarding Claim 6, Horiuchi discloses The medical endoscope system according to claim 5, wherein the subject is a gastrointestinal tract (par. 8 discloses an endoscope that is used to image the interior of a living body; therefore, it would be capable of imaging a gastrointestinal tract).
