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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 01/26/2026 has been entered.
Response to Arguments
Applicant’s arguments with respect to claim(s) 1-14 and 17-24 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
Response to Amendment
Applicant’s Amendment filed on 01/26/2026 regarding claims 1-24 is fully considered. Of the above claims, claims 15-16 have been canceled; claims 1 has been amended; claim 24 has been newly added.
Claim Objections
Claims 5 and 23 are objected to because of the following informalities:
Regarding claim 5, the recitation of “the printing speed” in line 3 lacks antecedent basis.
Regarding claim 23, the recitation of “non-carbon particles” in line 2 refers to a previously recited limitation.
Appropriate correction is required.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 24 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kim et al. (US 2018/0059839 A1).
Regarding claim 24, Kim et al. teach a printing process (a method for forming the strain gauge 450 on the second substrate layer 283 by using the laser transfer printing method; [0217]; FIG. 14) in which a substrate to be printed is disposed opposite an ink carrier having a liquid ink layer (the ink present in the ink station 1440 is coated on one side of a transparent endless belt 1460 by a roller 1450; [0219]; FIG. 14) and the liquid ink layer is irradiated regionally (laser 1480 is applied to the transparent endless belt 1460, so that the ink is transferred from the transparent endless belt 1460 to the surface of the second substrate layer 283; [0220]; FIG. 14), wherein the liquid ink layer comprises a liquid and carbon containing particles X dispersed in the liquid (a transparent material used for the strain gauge may include carbon nanotubes and graphene; [0145]; the ink, i.e., the strain gauge constituent material stored in a supplier 1410 is supplied to an ink station 1440; [0218]; FIG. 14), where said carbon containing particles X are present as carbon nanotube particles, graphene particles, graphene oxide particles, graphite oxide particles, fullerene particles and particles of graphite intercalation compounds, structural analogue particles of graphite, or a combination thereof (a transparent material used for the strain gauge may include carbon nanotubes and graphene; [0145]), and further wherein the liquid ink layer contains an amount of the carbon containing particles X dispersed in the liquid such that the liquid ink layer is sufficiently transparent to attain a transparent ink layer on the substrate upon irradiation (the light from the backlight unit must transmit through the strain gauge 450; [0139]).
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.
