Response to Amendment
This office action is in response to the amendment filed 02/02/26. Claims 1, 6, 15, and 24 have been amended, no new claims have been added, and no claims have been cancelled. Thus, claims 1-28 are presently pending in this application.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-28 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claims 1, 15, and 24 recites the limitation "the lower body" in lines 10, 12, and 10, respectively. There is insufficient antecedent basis for this limitation in the claim.
All remaining claims are rejected based on their dependency of a rejected base claim.
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.

Claim Rejections - 35 USC § 103
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 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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim(s) 3-4, 13, and 17-19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sankai as applied to claim 2 above, and further in view of Rodetsky (2009/0298653).
With respect to claims 3 and 17, the modified Sankai shows front and rear rollers (see claims 2 and 16 above) but lacks the front rollers and the rear rollers comprise omnidirectional wheels.
However, Rodetsky teaches a mobile gait device (elements of fig 1 not including the person (1)) with front rollers (only one side of the device is shown in fig 10 but would have two front wheels 23-1, fig 10) and rear rollers (only one side of the device is shown in fig 10 but would have two rear wheels 24-1, fig 10) comprising omnidirectional wheels (see [0065]) wherein at least one actuator actuates the omnidirectional wheels to facilitate the movement about the ground surface (see [0074]).
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 front and rear rollers of Sankai to include omnidirectional wheels as taught by Rodetsky so as to simulate normal walking patterns as the user walks forward, backward or makes turns (see [0011] of Rodetsky).

Annotated fig 10 of Rodetsky.
With respect to claims 4 and 18, the modified Sankai shows the plurality of rollers comprises omnidirectional tracks (see fig 10 of Rodetsky where the omnidirectional wheels comprise multiple rollers per wheel 23-1 on a track (see annotated fig 10 of Rodetsky where the multiple wheels as labeled form a track).
With respect to claim 13, Sankai shows all the elements as claimed above but lacks the user input interface comprises a transceiver operable to communicate with a mobile device.
However, Rodetsky teaches a mobile gait device (elements of fig 1 not including the person (1)) with an input interface (motion control and monitoring block; 13, fig 15) comprising a transceiver (not explicitly stated but the wireless signals from the remote device are received by 13, see [0074]) operable to communicate with a mobile device (remote control; 27, fig 15 and [0074]).
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 user input interface of Sankai to include a transceiver as taught by Rodetsky so as to enable the user to bring the apparatus from a remote location out of user's sight and serves as a communication device for a remote assistance, if necessary, the assistant can remotely take control over the apparatus (see [0014] of Rodetsky).
With respect to claim 19, the modified Sankai shows the user input interface (input unit; 230, fig 2 of Sankai) is communicatively coupled to the conveyance system (see connection to motor 218 in fig 2 of Sankai), the user input interface being operable to provide one or more inputs to the conveyance system to facilitate the movement of the walk-about platform about the ground surface (see [0035] of Sankai).
Claim(s) 7-8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sankai as applied to claim 6 above, and further in view of Takenaka (2022/0314428).
With respect to claim 7, the modified Sankai shows all the elements as claimed above but lacks the user input interface further comprises a force sensor.
However, Takenaka teaches a mobile device (51, fig 3) with a user input interface (90, fig 5) comprising a force sensor (81R, 81L, fig 3) to detect a force exerted by the operator (see [0133]) via a harness (70, fig 3), and wherein the conveyance system facilitates the movement of the device about the ground surface based on the detected force (see [0133]).
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 user input interface of Sankai to include a force sensor as taught by Takenaka so as to control movement of the device based on detected data in addition to manual inputs.
With respect to claim 8, the modified Sankai shows the force sensor comprises a six degree of freedom force moment sensor (see [0133] of Takenaka).
Claim(s) 9-10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sankai as applied to claim 6 above, and further in view of Ang (12,036,158).
With respect to claim 9, the modified Sankai shows all the elements as claimed above but lacks the user input interface comprises a position sensor.
However, Ang teaches a mobility aid (200, fig 2C) with a user input interface (230, fig 2C) comprises a position sensor (col. 19, lines 49-55) operable with a harness (232, fig 2C) to detect a position of the operator (col. 19, lines 55-63), and wherein a conveyance system facilitates the movement of the mobility aid about the ground surface based on the detected position (col. 20, lines 2-10).
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 user input interface of Sankai to include a position sensor as taught by Ang so as to an ease of movement of the device based on the user rather than only manual inputs.
With respect to claim 10, the modified Sankai shows the position sensor comprises a displacement sensor (see col. 19, lines 56-58 of Ang).
Claim(s) 11-12 and 23 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sankai as applied to claims 5 and 15 above, and further in view of Lee (9,789,023).
With respect to claim 11, the modified Sankai shows all the elements as claimed above but lacks the user input interface comprises an ultrasonic sensor.
However, Lee teaches a walking assist device (1, fig 1) with a user interface (5, fig 1) comprises an ultrasonic sensor (54, fig 1) operable to sense a position of the operator (col. 7, lines 41-53), and wherein a conveyance system facilitates the movement (for controlling speed of movement) of the device about the ground surface based on the detected position (col. 7, lines 41-53, where the sensor detects the distance i.e., a position of the user from the main navigation device).
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 user input interface of Sankai to include an ultrasonic sensor on a base (216, fig 8 of Sankai) as taught by Lee so as to allow for automatic navigation of the device and to avoid objects in the path of movement.
With respect to claim 12, the modified Sankai shows the ultrasonic sensor is disposed on a walk-about base of the walk-about platform (see modification by Lee in claim 11 above), and wherein the optical or ultrasonic sensor detects a leg position of the operator (the modification by Lee would provide the leg position since the sensor determines the distance which would provide the location of the leg).
With respect to claim 23, the modified Sankai shows an interface (input unit; 230, fig 2 of Sankai) but lacks the interface that connects the walk-about exoskeleton to a remote navigation system.
However, Lee teaches a walking assist device (1, fig 1) with a user interface (5, fig 1) connecting an exoskeleton (3, fig 1) to a remote navigation system (5, fig 1) wherein a conveyance system is operably integrated with the remote navigation system via the interface (col. 7, lines 23-28), and the remote navigation system is configured to facilitate movement of the walk-about platform about the ground surface in an autonomous mode (col. 7, lines 23-39).
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 user input interface of Sankai to include a navigation system as taught by Lee so as to allow the user to move about to a desired location on their own.
Claim(s) 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sankai and Rodetsky as applied to claim 19 above, and further in view of Takenaka (2022/0314428).
With respect to claim 20, the modified Sankai shows all the elements as claimed above but lacks the user input interface further comprises a force sensor.
However, Takenaka teaches a mobile device (51, fig 3) with a user input interface (90, fig 5 comprising a force sensor (81R, 81L, fig 3) to detect a force exerted by the operator (see [0133]) via a harness (70, fig 3), and wherein the conveyance system facilitates the movement of the device about the ground surface based on the detected force (see [0133]).
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 platform of Sankai to include a force sensor as taught by Takenaka so as to control movement of the device based on detected data in addition to manual inputs.
Claim(s) 21 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sankai and Rodetsky as applied to claim 19 above, and further in view of Ang (12,036,158).
With respect to claim 21, the modified Sankai shows all the elements as claimed above but lacks the user input interface comprises a position sensor.
However, Ang teaches a mobility aid (200, fig 2C) with a user input interface (230, fig 2C) comprises a position sensor (col. 19, lines 49-55) operable with a harness (232, fig 2C) to detect a position of the operator (col. 19, lines 55-63), and wherein a conveyance system facilitates the movement of the mobility aid about the ground surface based on the detected position (col. 20, lines 2-10).
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 user input of Sankai to include a position sensor as taught by Ang so as to an ease of movement of the device based on the user rather than only manual inputs.
Claim(s) 22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sankai and Rodetsky as applied to claim 19 above, and further in view of Lee (9789023).
With respect to claim 22, the modified Sankai shows all the elements as claimed above but lacks the user input interface comprises an ultrasonic sensor.
However, Lee teaches a walking assist device (1, fig 1) with a user interface (5, fig 1) comprises an ultrasonic sensor (54, fig 1) operable to sense a position of the operator (col. 7, lines 41-53), and wherein a conveyance system facilitates the movement (for controlling speed of movement) of the device about the ground surface based on the detected position (col. 7, lines 41-53, where the sensor detects the distance i.e., a position of the user from the main navigation device).
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 user input interface of Sankai to include an ultrasonic sensor on a base (216, fig 8 of Sankai) as taught by Lee so as to allow for automatic navigation of the device and to avoid objects in the path of movement.
Response to Arguments
The arguments to the newly added claim limitations in claims 1-28 have been addressed in the above rejections.
Applicant's arguments filed 02/02/26 have been fully considered but they are not persuasive. On pg. 10 of the remarks Applicant argues "the walk-about exoskeleton system 100 of the present application is not a typical robotic asset of the preexisting remote navigation system 195, but rather a completely separate and independent system comprising components that enable it to be integrated into the preexisting remote navigation system having robotic assets of a different type.” This is not persuasive since the claim language does not require completely separate components but rather different types, which is read on by the prior art since the assets are different as seen in the rejection above. Therefore, the rejection stands.
