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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 04/27/2026 has been entered.
Response to Amendment
The amendment filed 03/26/2026 has been entered. Claims 1-13 & 15-16 remain pending in the application.
Response to Arguments
Applicant's arguments with respect to claims 1-13 & 15-16 have been considered but are seen as not persuasive, see reasoning below.
Regarding the priority documents, Examiner has received the priority documents.
Regarding amended claim 1, applicant argues that none of the prior art recites “wherein the conductive film and the porous membrane are in direct contact with each other” in which the limitation originally comes from now cancelled claim 14. This limitation was taught by Holzhacker in the Final rejection such that conductive film, 54a is in direct contact with the porous membrane 74 which is shown in figure 12-a. Applicant argues that Holzhacker does not have any conductive film opposite to a contact surface of the porous material, to which that limitation was in claim 1 not claim 14. Therefore, was already taught by Somasuntharam in view of Lucisano such that Holzhacker disclosed the deficiency of the conductive film and porous membrane being in direct contact with each other wherein Somasuntharam in view of Lucisano taught other layers being in between them. Applicant also argues that removal of the addition layers taught by Somasuntharam would render the device unsatisfactory. To which the examiner wants to point towards MPEP 2145 III where it is stated “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference.... Rather, the test is what the combined teachings of those references would have suggested to those of ordinary skill in the art.” Such that it would have suggested to one of the ordinary skill in the art to have direct contact between a porous membrane and a conductive film for the purpose of allowing for direct communication between two elements which is taught by Holzahacker in Paragraph [0075]. Therefore, Examiner stands by the rejection as taught in the final rejection.
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.
Claims 1, 4, 9, 13 & 15-16 are rejected under 35 U.S.C 103 as being unpatentable over Somasuntharam et al. (US 20210076993) herein referred to Somasuntharam and of Lucisano et al. (US 7894870) herein referred to as Lucisano in further view of Holzhacker (US 20110288393) herein referred to as Holzhacker.
Regarding Claim 1, Somasuntharam discloses a bio signal sensing electrode (Figure 2A) comprising: a conductive film containing particles of a layered material including one or plural layers (Figure 2A, 104) and a modifier or terminal T exists on a surface of the layer body (Paragraph [0087]; wherein a terminal can be used to modify an electrode and is applied to the electrode surface), wherein T is at least one selected from the group consisting of a hydroxyl group, a fluorine atom, a chlorine atom, an oxygen atom, or a hydrogen atom (Paragraph [0060]; wherein terminal can contain hydroxyl groups); and a porous membrane that contains a hydrophilic polymer (Figure 2A, 112, Paragraph [0048]; wherein the analyte modulating layer is formed by a reaction mixture comprising a diisocyanate, a hydrophilic polymer and wherein it regulates the amount of glucose that contacts an enzyme therefore having to pass through the layer which would make it porous), the porous membrane having a first surface opposing at least part of the conductive film and a second surface defining a contact surface with a subject (Paragraph [0072]; wherein 112 contacts an enzyme therefore contacting a subject on oneside and can be seen opposing the film 104 on the other side). However, Somasuntharam does not explicitly disclose wherein the one or plural layers includes a layer body represented by: MmXn wherein M is at least one metal of Group 3, 4, 5, 6, or 7, X is a carbon atom, a nitrogen atom, or a combination thereof, n is 1 to 4, m is more than n and 5 or less and wherein the conductive film and the porous membrane are in direct contact with each other.
Lucisano discloses a biosensing electrode wherein a conductive layer includes a layer body represented by: MmXn wherein M is at least one metal of Group 3, 4, 5, 6, or 7, X is a carbon atom, a nitrogen atom, or a combination thereof, n is 1 to 4, m is more than n and 5 or less (Column 5 lines 13-21; wherein mixing titanium and carbide will create titanium carbide which is Ti2C therefore fitting the format of MmXn and the conductive thick film and the substrate are seen as one layer since they are heated together). Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to have modified the conductive film taught by Somasuntharam to consist of the layer taught by Lucisano. The motivation being it would be obvious to try different particles in a material to see which provides the best conductive properties (MPEP 2143 (E)).

TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 SPQ 232 (1984). In the instant case, the device of Somasuntharam and Lucisano in further view of Holzhacker would not operate differently with the claimed thickness, the device would function appropriately having the claimed thickness. Further, applicant places no criticality on the range claimed, indicating simply that the diameter “preferably” be within the claimed ranges (see Specification [0058]).
