One on each lower limb and one on the lower back. Step (b) should be rewritten to refer to the “at least 3 motion and/or angle sensors throughout the claim to reflect this. For example, claim 1, lines 11-12 could be written as “wherein the at least three motion and/or angle sensors are configured …”. Additionally, claims 4-5 and 13-14 should also reflect this change. Claim 4, line 2, “disposed near” should read “disposed on”. Appropriate correction is required. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. 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. Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Luinge (US 20080285805) and Oddsson (US 20050131317). Regarding claim 1, Luinge discloses a system for improving sensorimotor function of a patient, the system comprising: (a) at least one force and/or pressure sensor attached to or disposed on at least one lower limb or prosthesis of a patient, wherein the at least one force and/or pressure sensor is configured to detect force and/or pressure information relating to the lower limb or prosthesis and transmit force and/or pressure signals based on the force and/or pressure information (Paragraphs 0036 and 51, wherein force sensing shoes include sensors under the heel and forefoot to collect six degree-of-freedom force and moment measurements); (b) at least one motion and/or angle sensor attached to or disposed on each at least one lower limb or prosthesis and a lower back or lower lumbar region of a patient, wherein the at least one motion and/or angle sensor is configured to detect motion and/or angle information relating to the lower limb or prosthesis and the lower back or lower lumbar region and transmit motion and/or angle signals based on the motion and/or angle information (Fig. 1, sensor modules located on each lower limb and the lower back/lumbar region of the patient; Paragraph 0030, wherein the sensor modules capture 3D position and orientation data, gathering motion data with dix degrees of freedom. The sensor modules collecting the data via inertial sensors such as accelerometers, gyroscopes, or magnetometers); [AltContent: arrow][AltContent: arrow][AltContent: arrow][AltContent: arrow][AltContent: textbox (Motion/angle sensor disposed the lower back/lumbar region)][AltContent: textbox (Motion/angle sensors disposed on each lower limb)] PNG media_image1.png 583 513 media_image1.png Greyscale (c) a processor configured to receive the force and/or pressure signals and the motion and/or angle signals (Paragraph 0040 and Fig. 3, wherein the sensor fusion circuit 306 is a digital signal processor that obtain estimates of position, velocity, and orientation), generate, in real time, a patient-specific virtual biomechanical model comprising an electronic, real-time full-body human model based on the force and/or pressure signals and the motion and/or angle signals (Paragraph 0033, wherein a biomechanical model assumes a subject’s body includes body segments linked by joints. The model includes 23 segments linked by 22 joints; Paragraph 0043, wherein the sensor fusion algorithms are expandable to a complete body segment model) to calculate an estimated center of pressure and a center of gravity (Paragraph 0051, wherein the sensor fusion circuit 306 estimates the subject’s center of mass and center of gravity). Luinge discusses that motion capture and analysis systems are used in a variety fields, such as medicine and rehabilitation (Paragraph 0003). However, Luinge fails to disclose generating balance stimulation signals based on the estimated center of pressure and the center of gravity using the electronic, real-time full-body human model, and the system comprising at least one sensory stimulation unit disposed on at least one lower limb or prosthesis of the patient, wherein the at least one sensory stimulation unit comprises at least two stimulators that are actuable to provide stimulation to the patient based on the balance stimulation signals. Luinge and Oddsson are in the same field of motion analysis. Oddsson teaches a feedback device for measuring balance and producing a stimulation to the wearer. The system includes a stimulation array comprising a vibrotactile feedback array 40 connected to a band worn around the lower limb (Fig. 4). The stimulators respond to the estimates of the center of pressure and/or weight distribution and provides a vibratory stimulus to the user (Paragraphs 0021 and 0070). The model, created using the estimations of the motion and forces provided from the wearable sensors, calculates the center of pressure and gravity as disclosed by Luinge combined with using the center of pressure to stimulate the user with a wearable vibrotactile feedback as taught by Oddsson reads on the claim limitation of “generate balance stimulation signals based on the estimated center of pressure and the center of gravity using the electronic, real-time full-body human model”. As Luinge suggests various uses of the motion capture system for medical and rehabilitative purposes, Oddsson uses motion analysis to provide stimulation to a user via a vibrotactile feedback array based on a center of pressure calculated from the motion sensors. Luinge discloses the center of pressure and gravity measurements from the force sensing shoes and other sensors that contribute to the full-body human model, and Oddsson uses the measurements to provide stimulations to the user. Luinge would benefit from the combination as a user wearing the system would be able to achieve improved upright balance control, reducing risk of falls and injuries (as discussed by Oddsson in paragraph 0006). 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 system of Luinge to incorporate the stimulation array based on center of pressure measurements as taught by Oddsson, the benefit being improved upright balance control, reducing risk of falls and injuries, for the user. Regarding claim 2, the combination of Luinge and Oddsson disclose the system of claim 1. Luinge further discloses wherein a first of the at least one force and/or pressure sensor is disposed within or integral with a first pad, wherein the first pad is disposable under a first foot or prosthetic foot of the patient (Paragraph 0051, wherein aiding sensors include force sensing shoes, the force shoes having sensors under the heel and forefoot capable of collecting six degrees-of-freedom). Regarding claim 3, the combination of Luinge and Oddsson disclose the system of claim 2. Luinge further discloses wherein a second of the at least one force and/or pressure sensor is disposed within or integral with a second pad, wherein the second pad is disposable under a second foot or prosthetic foot of the patient (Paragraph 0051, wherein aiding sensors include force sensing shoes, the force shoes having sensors under the heel and forefoot capable of collecting six degree-of-freedom; Examiner notes that Luinge discloses force sensing shoes; as such, two pads are disclosed, each with at least one force sensor). Regarding claim 4, the combination of Luinge and Oddsson disclose the system of claim 1. Luinge further discloses wherein the at least one motion and/or angle sensor comprises five motion and/or angle sensors attached to or disposed on a right foot or ankle, a left foot or ankle, a right thigh, a left thigh, and the lower back or lower lumbar region of the patient (see below). [AltContent: arrow][AltContent: textbox (Motion/angle sensors disposed on each foot/ankle and each thigh)][AltContent: textbox (Motion/angle sensor disposed on the lower back/lumbar region)][AltContent: arrow][AltContent: arrow] PNG media_image1.png 583 513 media_image1.png Greyscale Regarding claim 5, the combination of Luinge and Oddsson disclose the system of claim 4. Luinge further discloses wherein each of the five motion and/or angle sensors is an inertial motion unit disposed within a sensor processing module (Paragraph 0030 and Fig. 1, wherein the sensor modules 102 collect 3D inertial sensor data via accelerometers and gyroscope, and optionally, magnetometers). Regarding claim 6, the combination of Luinge and Oddsson disclose the system of claim 1. Oddsson further discloses wherein the at least one sensory stimulation unit comprises a first stimulation unit disposed on a first lower limb or prosthesis of the patient and a second stimulation unit disposed on a second lower limb or prosthesis of the patient (Fig. 5 and paragraph 0071, wherein the vibro-tactile array 52 is located on one or more legs of the user. The array includes three vibrator levels, each with four vibrators each). Regarding claim 7, the combination of Luinge and Oddsson disclose the system of claim 1. Oddsson further discloses wherein the at least one sensory stimulation unit comprises a band with four vibrotactile actuators disposed on the band (Fig. 5 and paragraph 0071, wherein the vibro-tactile array 52 is located on one or more legs of the user. The array includes three vibrator levels, each with four vibrators each). Regarding claim 8, the combination of Luinge and Oddsson disclose the system of claim 1. Luinge further discloses a user interface operably coupled to the processor, wherein the user interface comprises a display (Fig. 9, PC/laptop 906 with screen coupled to bus module 904). Although Luinge does not explicitly state that the laptop displays the human body model, Luinge discloses that the computer receives the orientation and position estimates for synchronization of sensor information and processing of sensor data into a sensor fusion circuit (Paragraph 0056). The sensor fusion circuit combines the model constraints and uses algorithms that are expandable to a complete body segment model (Paragraphs 0040 and 0043). It would be obvious for one of ordinary skill in the art to then display the model on the screen of the laptop to provide the user a visual interpretation of the data. Regarding claim 9, the combination of Luinge and Oddsson disclose the system of claim 8. Luinge further discloses wherein the user interface comprises an application in a mobile device (Fig. 9, PC/laptop 906). Regarding claim 10, the combination of Luinge and Oddsson disclose the system of claim 9. Luinge further discloses wherein the mobile device comprises a laptop or a smartphone (Fig. 9, PC/laptop 906).

The sensor modules collecting the data via inertial sensors such as accelerometers, gyroscopes, or magnetometers); [AltContent: arrow][AltContent: arrow][AltContent: arrow][AltContent: arrow][AltContent: textbox (Motion/angle sensor disposed the lower back/lumbar region)][AltContent: textbox (Motion/angle sensors disposed on each lower limb)] PNG media_image1.png 583 513 media_image1.png Greyscale (c) a processor configured to receive the force and/or pressure signals and the motion and/or angle signals (Paragraph 0040 and Fig. 3, wherein the sensor fusion circuit 306 is a digital signal processor that obtain estimates of position, velocity, and orientation), generate, in real time, a patient-specific virtual biomechanical model comprising an electronic, real-time full-body human model based on the force and/or pressure signals and the motion and/or angle signals (Paragraph 0033, wherein a biomechanical model assumes a subject’s body includes body segments linked by joints.

Although Luinge does not explicitly state that the laptop displays the human body model, Luinge discloses that the computer receives the orientation and position estimates for synchronization of sensor information and processing of sensor data into a sensor fusion circuit (Paragraph 0056).

However, Luinge fails to disclose generating balance stimulation signals based on the estimated center of pressure and the center of gravity using the electronic, real-time full-body human model, and the system comprising at least one sensory stimulation unit disposed on at least one lower limb or prosthesis of the patient, wherein the at least one sensory stimulation unit comprises at least two stimulators that are actuable to provide stimulation to the patient based on the balance stimulation signals. Luinge and Oddsson are in the same field of motion analysis. Oddsson teaches a feedback device for measuring balance and producing a stimulation to the wearer. The system includes a stimulation array comprising a vibrotactile feedback array 40 connected to a band worn around the lower limb (Fig. 4). The stimulators respond to the estimates of the center of pressure and/or weight distribution and provides a vibratory stimulus to the user (Paragraphs 0021 and 0070).

However, as Luinge and Oddsson disclose sensors and stimulators, respectively, on the lower limbs, one of ordinary skill in the art would be motivated to combine them into one module together to reduce cost and components of the overall system. 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 combined the sensor modules of Luinge with the stimulators of Oddsson, the benefit being reduced cost and components of the system. Regarding claim 20, the combination of Luinge and Oddsson disclose the system of claim 17. Luinge further discloses wherein the user interface comprises an application in a mobile device (Fig. 9, PC/laptop 906), wherein the mobile device comprises a laptop, or a smartphone (Fig. 9, PC/laptop 906). Response to Arguments Examiner acknowledges Applicant’s arguments of the claim interpretation under 112(f). Examiner agrees with Applicant that the claims, as amended, recite sufficient structure for the elements laid out in the Office Action mailed 03/31/2026. Therefore, the elements are no longer interpreted under 112(f). Applicant’s arguments, see pages 10-12, filed 07/30/2026, with respect to the 35 U.S.C. §112(b) rejections have been fully considered and are persuasive. Applicant has amended the claims to recite that the processor uses the force/pressure signals and motion/angle signals to generate an electronic, real-time full-body human model and calculate an estimated center of pressure and center of gravity. Applicant has amended the claims to recite that the sensors are attached to or disposed on the body of the patient. Applicant has amended the claims to recite that the sensors are disposed in or integral with the first pad. Applicant has amended the claims to recite that the motion/angle sensors are attached to the band rather than “associated with” one of the four stimulators. The rejection of the claims has been withdrawn. Applicant’s arguments, see pages 12-18, filed 07/30/2026, with respect to 35 U.S.C. §102(a)(1) rejections have been fully considered are persuasive. Applicant asserts that Czaja fails to teach or suggest the motion and/or angle sensors or the electronic, real-time full-body human model as claimed. Examiner agrees that Czaja fails to disclose at least 3 motion and/or angle sensors and an electronic, real-time full-body human model. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Luinge and Oddsson as described above. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
