DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Amendment
The amendment filed October 20th, 2025 has been entered. Claims 1-20 remain pending in the application. Applicant’s amendments to the claims have overcome the objections and 112(b) rejections previously set forth in the Non-Final Office Action mailed July 18th, 2025.
Response to Arguments
Applicant’s arguments, see Pages 8-9, filed 10/20/2025, with respect to the rejection(s) of claim(s) 1 under 35 U.S.C. 102(a)(1)/102(a)(2) have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Pushpala in view of Stemme (see rejection below).
Applicant’s arguments, see Pages 9-16, filed 10/20/2025, with respect to the rejection(s) of claim(s) 3-11 and 13-15 under 35 U.S.C. 112(b) have been fully considered and are persuasive. Therefore, the rejection has been withdrawn.
Applicant's arguments filed 10/20/2025, regarding the rejection of claim 16, see Pages 16-18 have been fully considered but they are not persuasive. The applicant has argued that Lisy does not discloses the hardness of the penetrators nor the ionic compound, however the examiner has shown that the relative hardness of the penetrator is harder than the hardness of the ionic compound as evidenced by the “Technical data sheet for Silicon” and “Technical data sheet for Silver”. In response to applicant's argument that the purpose of the softer material is to help the contact surface conform to the contours of a user’s finger in spaces between the unit cell contact edges, responsive to applied pressure, the fact that the inventor has recognized another advantage which would flow naturally from following the suggestion of the prior art cannot be the basis for patentability when the differences would otherwise be obvious. See Ex parte Obiaya, 227 USPQ 58, 60 (Bd. Pat. App. & Inter. 1985). Further, it is not explicitly disclosed within the claim that the softer material is only disposed within the gaps of the unit cells and does not cover the entire surface of the unit cells, therefore applicant’s arguments are not seen as persuasive.
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.
Claim(s) 1-7, 12 and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Pushpala et al. (US 2017/0128009 A1) herein referred to as “Pushpala” in view of Stemme et al. (US 2004/0054393 A1) herein referred to as “Stemme”.

and a separate electrically-conductive coating covering each electrode (coating for each electrode, Figures 2A-2F), each electrically-conductive coating including: a base portion (base portion 130, Figures 2A-2F); and a plurality of unit cells extending from the base portion (unit cells (protrusions 130) extend from the base portion 130, Figures 2A-2F), wherein the unit cells are formed from a same material (the substrate 130 is processed to form at least one protrusion (seen as the unit cells), wherein the substrate has a uniform composition, and can be composed of a semiconducting material, a conducting material, and/or an insulating or non-conductive material, Paragraph [0032]), wherein the material forming the unit cells has a first hardness (the substrate 130 can be formed of a semiconducting material such as silicon, wherein silicon has a first hardness, Paragraph [0032], (Mohs hardness of silicon is 6.5 (see attached Technical Data Sheet for silicon)), wherein each unit cell is spaced apart at least a predetermined distance from any adjacent unit cell so as to provide a gap therebetween (protrusions 130 are spaced apart at least a predetermined distance, Figures 2A, and 5C).
Pushpala does disclose the use of a material in the gap between each protrusion (biocompatible layer 185 to enhance biocompatibility of the filament 120, Figure 2E, Paragraph [0043]), however Pushpala does not explicitly disclose and wherein all gaps between adjacent unit cells are filled in with a conductive material having a second hardness less than the first hardness.
Lisy discloses a physiological recording device used for recording signals on a user’s skin (Abstract) wherein all gaps between adjacent unit cells are filled in with a conductive material having a second hardness less than the first hardness (surface features 102 are penetrators (seen as unit cells), Col. 25, lines 49-51, wherein the gaps between surface features 102 are with a conductive material 104 which can be made of silver/silver chloride (Ag/AgCl), Col. 25, lines 34-39, Figures 1C and 2E, (Mohs hardness scale of silver is 2.5 (see attached Technical Data Sheet for silver)).
It would have been prima facie obvious to one of ordinary skill in the art before
the effective filing date of the claimed invention to have modified Pushpala to incorporate the teachings of Lisy by including wherein all gaps between adjacent unit cells are filled in with a conductive material having a second hardness less than the first hardness. The motivation to do so being to minimize electrical impedance and provide a conductive electrical pathway for biopotentials to be transmitted from the lower layers of the patient’s skin to the monitoring equipment (Lisy, Col. 25, lines 39-46).
