Office Action

§102
CTNF 18/787,061 CTNF 82745 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Election/Restrictions 08-25-01 AIA Applicant’s election without traverse of Invention I in the reply filed on 4/6/26 is acknowledged. 08-06 AIA Claim s 3-8 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected Invention , there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 4/6/26 . Priority 02-26 AIA Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Claim Objections 07-29-01 AIA Claim 1 is objected to because of the following informalities: it is clear from applicant’s figs. 6 and 10 that the last indented section of claim 1 should read: “the detection resistor includes an overlapping region overlapping the common electrode and a non-overlapping region not overlapping the common electrode at a cross-section where the pressure chamber substrate is sectioned at a position where the pressure chamber is present on a plane parallel to a longitudinal direction of the pressure chamber the plurality of pressure chambers and the direction of lamination.” Appropriate correction is required. Claim Rejections - 35 USC § 102 07-07-aia AIA 07-07 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 – 07-08-aia AIA (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. 07-12-aia AIA (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. 07-15-aia AIA Claim(s) 1-2 and 9-10 is/are rejected under 35 U.S.C. 102 (a)(1)/(a)(2) as being anticipated by Mori et al. (US 20230249462 A1) . Regarding claim 1 , Mori discloses A liquid ejecting head comprising: a pressure chamber substrate (23, fig. 2, para 115) including a pressure chamber line (see fig. 2) having a plurality of pressure chambers (CV1, fig. 2, para 115) arranged in a first direction (Y, fig. 2); a plurality of individual electrodes individually provided to the plurality of pressure chambers (Qc, fig. 6, para 87); piezoelectric bodies laminated on the plurality of individual electrodes (Qm, fig. 6,7, para 87), respectively, and driven in order to apply a pressure to a liquid inside the plurality of pressure chambers (inherent in fig. 6); a common electrode (Qb, fig. 6,7, para 79) including at least one electrode provided in common to the plurality of pressure chambers and laminated on the piezoelectric bodies (see fig. 4, para 79); and a detection resistor (TK, fig. 6,7, para 69-70) disposed on a lower side of the piezoelectric bodies in a direction of lamination to laminate the plurality of individual electrodes (see fig. 6,7), the piezoelectric bodies, and the common electrode and at a position not overlapping the plurality of individual electrodes (see fig. 6,7), formed from an identical material to a material of at least any of the plurality of individual electrodes and the common electrode (see Abstract, para 5,74,82-83,85), and configured to change a resistance value in response to a temperature of the liquid inside the plurality of pressure chambers (see para 63,65,69,93-95), wherein the detection resistor includes an overlapping region overlapping the common electrode (see central portion, in the X direction, of TKx1, fig. 7, that does not overlap with Qb) and a non-overlapping region not overlapping the common electrode at a cross-section where the pressure chamber substrate is sectioned at a position where the pressure chamber is present on a plane parallel to a longitudinal direction of the pressure chamber the plurality of pressure chambers and the direction of lamination (see left portion, in the X direction, of TKx1, fig. 7, that does not overlap with Qb). Regarding claim 2 , Mori further discloses The liquid ejecting head according to claim 1, wherein the overlapping region is located at position closer to the pressure chambers in the longitudinal direction than the non-overlapping region is (see fig. 7). Regarding claim 9 , Mori further discloses A liquid ejecting apparatus comprising: the liquid ejecting head according to claim 1; a resistance value acquisition unit that acquires a resistance value of the detection resistor; and a temperature acquisition unit that acquires a temperature near the pressure chambers based on the resistance value acquired by the resistance value acquisition unit (see para 63,69,93-95,115-120,126,129,133,136,141-145,149,156,160). Regarding claim 10 , Mori further discloses The liquid ejecting apparatus according to claim 9, further comprising: a drive waveform determination unit that determines a drive waveform to be applied to the plurality of individual electrodes based on the temperature acquired by the temperature acquisition unit (72, fig. 1, para 94).
