Remarks This action is in response to the remarks filed 07/15/2026. Claims 1-6 and 9-24 are pending and are under consideration. Response to Arguments Applicant’s arguments, see page 6, filed 07/15/2026, with respect to objection of claim 2 have been fully considered and are persuasive. The objection of claim 2 has been withdrawn. Applicant’s arguments, see page 7, filed 07/15/2026, with respect to the rejection of claims 11-14 under 35 U.S.C. 112(b) have been fully considered and are persuasive. The rejection of claims 11-14 under 35 U.S.C. 112(b) has been withdrawn. Applicant’s arguments, see page 7, filed 07/15/2026, with respect to the rejection of claims 17-19 under 35 U.S.C. 101 for reciting a part of a human have been fully considered and are persuasive. Claims 17-19 have been amended to recite language that overcomes this rejection. Therefore, the rejection of claims 17-19 under 35 U.S.C. 101 for reciting a part of a human has been withdrawn. Applicant’s arguments, see page 7, filed 07/15/2026, with respect to the rejection of claims 1-21 under 35 U.S.C. 101 have been fully considered and are persuasive. Independent claim 1 has been amended to recite the limitation of “adjust a therapy of the patient based on the one or more statistics.” This limitation integrates the abstract idea into a practical application.

Regarding claim 24, Goodall further discloses stimulating the cutaneous distribution of a patient's vagus nerve via a vibration (e.g. page 60, lines 25-27: vibrotactile device can be used). 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 3 is rejected under 35 U.S.C. 103 as being unpatentable over Goodall et al. (International Publication WO 2018/111997, of record), hereinafter Goodall, as applied to claim 1 above, and further in view of Edgerton et al. (US Patent Application Publication 2018/0280693 – APPLICANT CITED ON IDS, of record), hereinafter Edgerton. Regarding claim 3, Goodall fails to disclose wherein the physical activity is assisted by a powered exoskeleton that assists and/or guides the physical activity of the patient. Edgerton, in a similar field of endeavor, is directed towards using a neuromodulation stimulator and a robotic exoskeleton. Edgerton discloses using a powered exoskeleton to assist the user in performing a physical activity (e.g. Abstract; Pars. [0171]-[0173]: powered exoskeleton for providing assistance in locomotion to the user; Fig. 1: exoskeleton with trunk portion 110 and lower leg supports 112; Fig. 2: powered orthotic system 200). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the invention of Goodall to include the exoskeleton as taught by Edgerton because doing so would allow the user to supplement neurostimulation with the exoskeleton to assist the user in standing and walking (e.g. Edgerton, par. [0005]). Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Goodall et al. (International Publication WO 2018/111997, of record), hereinafter Goodall, as applied to claim 1 above, and further in view of Goldwasser et al. (US Patent Application Publication 2017/0224990 – APPLICANT CITED ON IDS, of record), hereinafter Goldwasser. Regarding claim 4, Goodall fails to disclose wherein the physical activity is assisted by a virtual reality headset. Goldwasser, in a similar field of endeavor, is directed towards neuromodulation. Goldwasser discloses using a virtual reality headset to control the neuromodulation (e.g. Par. [0781]; Par. [0075]: device is worn during daily activities). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the invention of Goodall to include the virtual reality headset as taught by Goldwasser in order to introduce a sensory experience during the stimulation (e.g. Goldwasser, par. [0781]). Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Goodall et al. (International Publication WO 2018/111997, of record), hereinafter Goodall, as applied to claim 1 above, and further in view of Edgerton et al. (US Patent Application Publication 2014/0296752 – APPLICANT CITED ON IDS, of record), hereinafter Edgerton’752. Regarding claim 9, Goodall fails to disclose wherein the patient previously suffers from multiple sclerosis. Edgerton’752, in a similar field of endeavor, is directed towards inducing motor control in mammals through stimulation. Edgerton’752 discloses wherein the patient previously suffers from multiple sclerosis (e.g. Par. [0010]; Par. [0046]). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the invention of Goodall to include wherein the patient previously suffers from multiple sclerosis as taught by Edgerton’752 to provide stimulation to control motor faculties affected by multiple sclerosis (e.g. Edgerton’752, par. [0010]; par. [0046]). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Badran et al. (US 2022/0296889, of record) discloses a system for neurorehabilitation with vagus nerve stimulation. Simon et al. (US 11,191,953, of record) discloses systems and methods for vagal nerve stimulation. Covalin et al. (US 2021/0213286, of record) discloses a neurostimulation device wearable around the ear of the patient. Howard (US 2019/0381314, of record) discloses transcutaneous nerve stimulation to enhance speed and quality of cognitive brain function. Goodall et al. (US 2018/0169411, of record) discloses a prompting system for enhancing learning with neural modulation. 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.
