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) 4, 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ishimoto as applied to claims 2, 8 above, and further in view of Shimazu et al. (US 2020/0302657 A1).
In regards to claim 4, Ishimoto teaches the shovel of claim 2, but does not explicitly teach the shovel, wherein the display device is configured to change a display mode in the predetermined display area when the person is detected in the direction represented by the third display information.
However, Shimazu teaches a shovel, wherein the display device is configured to change a display mode in the predetermined display area when the person is detected in the direction of movement (e.g. [0084],Fig.4: controller 33 determines whether one or more conditions are met on the basis of a relative positional relationship between a detection object detected within the display region 62 of the first video image and the moving body 50; for example, a first condition specifying that the detection object is located on the first predicted path 65 of the moving body 50; when the controller 33 determines that one or more of the conditions are met, the controller 33 may cause a predetermined marker corresponding to the detection object to be superimposed on the second video images and displayed on the display apparatus 40; Examiner’s note: this shows marker display based on object detected in direction of movement).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the teachings/combination of Ishimoto to change display mode, in the same conventional manner as taught by Shimazu as both deal with object detection. The motivation to combine the two would be that it would allow display of indicator for objects detected in the direction that the shovel is moving.
In regards to claim 12, Ishimoto teaches the shovel of claim 8, but does not explicitly teach the shovel, wherein in response to determining that a person exists in an area not represented as the image information based on the position information, the display device is configured to arrange display information indicating that a person exists, in a direction in which the person exists, in the predetermined display area.
However, Shimazu teaches a vehicle, wherein in response to determining that a person exists in an area not represented as the image information based on the position information, the display device is configured to arrange display information indicating that a person exists, in a direction in which the person exists, in the predetermined display area (e.g. [0099],Fig.10: when a detection position of the detection object in the first video image is outside of the display region 62 and, simultaneously, inside of the detection region 61, the controller 33 may cause a marker corresponding to the detection object to be superimposed on the second video image and displayed on the display apparatus 40; hereinafter, this marker will also be referred to as a fifth marker; when the detection position of the detection object in the first video image is located on the right side of the display region 62, the controller 33 may cause the fifth marker to be superimposed on the right-side edge region of the second video images and displayed on the display apparatus 40).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the teachings/combination of Ishimoto to change display mode, in the same conventional manner as taught by Shimazu as both deal with object detection. The motivation to combine the two would be that it would allow the display of an indicator of objects detected that are not within the displayed view.
Claim(s) 5-7, 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ishimoto as applied to claims 2, 9 above, and further in view of Danguchi et al. (US 2023/0407602 A1).
In regards to claim 5, Ishimoto teaches a shovel, wherein the display device is configured to display a plurality of first areas, which are determined in accordance with a distance from the shovel, in the predetermined display area (e.g. as above, [0050]: in Fig.3, an area where there is a potential danger of contact with a moving or fixed obstacle as an object to be avoided to avoid a collision is set as a dangerous zone Z1; as a range required for the assurance of safety, another circle of a predetermined radius is drawn on an outer side of the circle, and the area between these two circles is set as a warning zone Z2), but does not explicitly teach the shove, wherein the display device is configured to differentiate the display mode of the second display information according to whether or not the second display information is included in a corresponding first area of the first areas.
However, Danguchi teaches a shovel, wherein the display device is configured to differentiate the display mode of the second display information according to whether or not the second display information is included in a corresponding first area of the first areas (e.g. [0121]-[0122],Fig.12: the display control unit may cause the display unit 61 to display warning information D5 indicating that the obstacle is present when the image recognition unit 53 detects the obstacle; in the example of Fig.12, the display unit 61 displays as the warning information D5 an icon A1 indicating a “human” of being an obstacle, an arrow icon A2 indicating a direction in which the human is present, and an arc strip-shape area A3 (see thick dashed line) indicating that the human is on the left side of the hydraulic excavator 1; furthermore, the display unit 61 also displays as warning information D5 an icon B1 indicating a “human” of being an obstacle, an arrow icon B2 indicating a direction in which the human is present, and an arc strip-shape area B3 (see thick solid line) indicating that the human is behind the hydraulic excavator 1).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the teachings/combination of Ishimoto to change display mode, in the same conventional manner as taught by Danguchi as both deal with object detection. The motivation to combine the two would be that it would allow the display of warning indicators that help differentiate between objects.
In regards to claim 6, the combination of Ishimoto and Danguchi also teaches a shovel, wherein when a plurality of portions of the second display information are included in one of the first areas, the display device is configured to display the plurality of portions of the second display information distinguishably (e.g. Ishimoto, [0068],Fig.12A: three worker icons M1, M2, M3 have appeared on the rear virtual viewpoint image 22B in the state that the standard image display pattern A is displayed on the monitor 20; Examiner’s note: captured imagery is displayed, from which the moving obstacles are detected; Fig.12A shows the plurality of people are distinguishably displayed).
In regards to claim 7, the combination of Ishimoto and Danguchi also teaches a shovel, wherein the first areas displayed by the display device are based on the first display information, and are at least one of a range in which a current attachment of the shovel rotates, or a range in which the attachment of the shovel rotates when the attachment of the shovel is most extended in a horizontal direction (e.g. Ishimoto as above, [0050]: in Fig.3, an area where there is a potential danger of contact with a moving or fixed obstacle as an object to be avoided to avoid a collision is set as a dangerous zone Z1; as a range required for the assurance of safety, another circle of a predetermined radius is drawn on an outer side of the circle, and the area between these two circles is set as a warning zone Z2; Examiner’s note: the displayed circular zones, Z1 and Z2 in Fig.3, suggest they correspond to the range of the rotation of the shovel) .
In regards to claim 10, the combination of Ishimoto and Danguchi also teaches a shovel, wherein the display device is configured to differentiate the display mode of the area shown on the image information, and the second image information, based on the distance between the shovel and the person (e.g. Danguchi as above, [0121]-[0122],Fig.12: in the example of Fig.12, the display unit 61 displays as the warning information D5 an icon A1 indicating a “human” of being an obstacle, an arrow icon A2 indicating a direction in which the human is present, and an arc strip-shape area A3 (see thick dashed line) indicating that the human is on the left side of the hydraulic excavator 1; furthermore, the display unit 61 also displays as warning information D5 an icon B1 indicating a “human” of being an obstacle, an arrow icon B2 indicating a direction in which the human is present, and an arc strip-shape area B3 (see thick solid line) indicating that the human is behind the hydraulic excavator 1; Examiner’s note: Fig.12 shows differentiation of areas and people within a certain distance of shovel).
In addition, the same rationale/motivation of claim 5 is used for claim 10.
