This allows for proper electrical connection contact of the electrodes to the wearer of the wearable electronic device. Therefore, it would have been obvious to one of ordinary skill in the art, at the time of filing, to modify the device of Block by adding electrodes coupled to the substrate as taught by Pandya in order to facilitate proper electrical connection contact of the electrodes to the wearer of the wearable electronic device.
Regarding claim 14, Block in view of Han discloses the invention substantially as claimed however does not show the reference electrode is substantially semi- annular and wherein the negative electrode is substantially semi-annular. Pandya discloses the reference electrode is substantially semi- annular and wherein the negative electrode is substantially semi-annular (Fig. 2A, column 9 lines 63-65).

Claim Objections
Claims 5, 20 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Response to Arguments
Applicant's arguments filed 10/18/2024 have been fully considered but they are not persuasive. Examiner does find that Block does not specifically show a light barrier construct mounted on the substrate and defining a first emitter chamber that houses the first emitter group of LEDs, and a second emitter chamber that houses the second emitter group of LEDs, wherein the light barrier construct is configured to optically isolate the first emitter group of LEDs from the second emitter group of LEDs.

This allows for the improved signal strength and reduced noise. Therefore, it would have been obvious to one of ordinary skill in the art, at the time of filing, to modify the device of Block by adding light barrier as taught by Han in order to facilitate improved signal strength and reduced noise.
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).
