Regarding claim 13, Han teaches the foot electrical stimulation massager according to claim 2. Han further teaches wherein the negative electrode connection terminal is arranged on the second conductive region, and directly electrically connected to the second conductive region; or the negative electrode connection terminal is arranged separately from the second conductive region, and electrically connected to the second conductive region via printed circuit traces or wire connections ([0019], [0020], [0022], reference to Fig. 2). Regarding claims 19-20, the claims are directed to a massage device comprising substantially the same subject matter as claims 1-2 and are rejected under substantially the same sections of Han. 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. 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) 14-18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Han; in view of Chen (U.S. Patent Application Publication No. 2020/0139106) hereinafter referred to as Chen. Regarding claim 14, Han teaches the foot electrical stimulation massager according to claim 2. Han does not teach wherein the positive electrode connection terminal is a conductive snap-fit structure or a pin connection structure; the negative terminal is a conductive snap-fit structure or a pin connection structure. Attention is drawn to the Chen reference, which teaches wherein the positive electrode connection terminal is a conductive snap-fit structure or a pin connection structure; the negative terminal is a conductive snap-fit structure or a pin connection structure (¶[0117]). It would have been obvious to one of ordinary skill in the art at the time of filing to modify the electrode connection terminals of Han to include snap-fit structures, as taught by Chen, because the snaps releasably engage and electrically connect the electrode pad to a stimulation unit, which would improve hygiene (Chen ¶[0117]). Regarding claim 15, Han teaches the foot electrical stimulation massager according to claim 1. Han does not teach a foot massage cushion; wherein the first conductive region and the second conductive region are disposed on an outer surface of the foot massage cushion. Attention is drawn to the Chen reference, which teaches a foot massage cushion; wherein the first conductive region and the second conductive region are disposed on an outer surface of the foot massage cushion (¶[0118], ¶[0149], a slipper form includes an insole which functions as a cushion for the foot). It would have been obvious to one of ordinary skill in the art at the time of filing to modify the massager to Han to take the form of slippers, as taught by Chen, because the slippers can directly contact particular areas of the body surface, and a conformal surface can more easily be applied to body surfaces (Chen ¶[0118], ¶[0149]). Regarding claim 16, Han teaches the foot electrical stimulation massager according to claim 1. Han does not teach wherein the foot electrical stimulation massager is a slipper, the slipper comprising an insulative shoe sole; wherein the first conductive region and the second conductive region are both disposed on a surface of the insulative shoe sole, wherein the surface of the insulative shoe sole is close to the sole. Attention is drawn to the Chen reference, which teaches a foot electrical stimulation massager that is a slipper, the slipper comprising an insulative shoe sole; wherein the first conductive region and the second conductive region are both disposed on a surface of the insulative shoe sole, wherein the surface of the insulative shoe sole is close to the sole (¶[0118], ¶[0149]). It would have been obvious to one of ordinary skill in the art at the time of filing to modify the massager to Han to take the form of slippers, as taught by Chen, because the slippers can directly contact particular areas of the body surface, and a conformal surface can more easily be applied to body surfaces (Chen ¶[0118], ¶[0149]). Regarding claim 17, Han as modified teaches the foot electrical stimulation massager according to claim 16. Chen further teaches wherein the positive electrode connection terminal is disposed at an end corner, facing towards the second conductive region, on the first conductive region; and the negative electrode connection terminal is disposed at an end corner, opposite to the positive electrode connection terminal, on the second conductive region (above, Han teaches the configuration of positive and negative connected electrodes, Fig. 44, 50 of Chen shows their relative locations in the form of snap connector locations). Regarding claim 18, Han as modified teaches the foot electrical stimulation massager according to claim 16. Chen further teaches wherein a protrusion is formed on a side of the insulative shoe sole, wherein the side of the insulative shoe sole is for contacting with the sole, and the protrusion is positioned between the first conductive region and the second conductive region (¶[0232] insulation area, Fig. 50). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. U.S. Patent Application Publication No. 2017/0354816 to Huelman et al. teaches a variety of electrical stimulation substrates configured for parts of the body including feet. Chinese Patent Publication No. CN207118667U to Huang teaches a shoe-pad and wiring of positive and negative terminals. U.S. Patent Application Publication No. 2004/0059387 to Yu teaches an electrically stimulating pad or shoe.
