Claim Rejections - 35 USC § 103
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.
Claim(s) 3 and 5 are rejected under 35 U.S.C. 103 as being unpatentable over Shimoda et al. in view of Nishimura (US 20230410334 A1, hereinafter referred to as “Nishimura”).
Regarding claim 3, Shimoda teaches the image processing device according to claim 1, Shimoda fails to explicitly teach wherein the lumen corresponding region is an end part of an observation range of the camera in a direction in which a position of the lumen region is estimated from a fold region in the image.
However, Nishimura explicitly teaches wherein the lumen corresponding region is an end part of an observation range of the camera in a direction in which a position of the lumen region is estimated from a fold region in the image (“the recognition unit 264 recognizes the structure such as the lumen direction and the fold included in the endoscopic image together with the positional relationship in the depth direction using the region information and the depth information.” Nishimura, [0150]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to combine the teachings of Shimoda of having an image processing device comprising: a processor, wherein the processor is configured to: acquire a lumen direction that is a direction in which an endoscope is inserted, from an image obtained by imaging a tubular organ via a camera provided in the endoscope, in accordance with a trained model obtained through machine learning based on a positional relationship between a plurality of division regions obtained by dividing the image and a lumen corresponding region included in the image, with the teachings of Nishimura of having wherein the lumen corresponding region is an end part of an observation range of the camera in a direction in which a position of the lumen region is estimated from a fold region in the image.

The motivation behind the modification would have been to obtain endoscopic image processing device capable of providing position and direction of an endoscope to enhance guidance, since both Shimoda and Nishimura are directed to processing an image captured by an endoscope. Wherein Shimoda endoscopic insertion procedure helps guide the insertion part of an endoscope into an organ without damaging the inside of the organ, while Nishimura specifies a direction in which the endoscope is advanceable based on region information. Please see Shimoda et al. (JP 2021049314 A), Paragraph [0003] and Nishimura (US 20230410334 A1), Paragraph [0009].
