CTNF 18/951,873 CTNF 81623 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. Claim Rejections - 35 USC § 102 07-06 AIA 15-10-15 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. 07-15-aia AIA Claim(s) 1-4, 7-18 is/are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by Tamai et al (U.S. Pub. 2022/0234354) Regarding claim 1, a liquid ejecting head comprising a nozzle plate (51) on which a nozzle configured to eject a liquid is formed (Figure 3;

refer to figure below) Regarding claim 4, the length of a part of the communication flow path in the second direction between the first pressure chamber and the third pressure chamber is less than a width of the communication flow path in the first direction at a potion overlapping the nozzle in plan view seen toward the nozzle plate (Figure 4; refer to figure below) PNG media_image1.png 528 768 media_image1.png Greyscale Regarding claim 7, a total length in the second direction of the communication flow path is equal to or less than the length of the first pressure chamber in the second direction (Figure 4) Regarding claim 8, the total length in the second direction of the communication flow path is less than the length of the first pressure chamber in the second direction (Figure 4) Regarding claim 9, the first common liquid chamber is a flow path for supplying a liquid to the first and second pressure chambers; and the second common liquid chamber is a flow path for collecting a liquid from the third and fourth pressure chambers (Figure 4; Paragraph 0056) Regarding claim 10, a first flow path that is communication the first pressure chamber with the communication flow path and that extends in a third direction, the third direction being a thickness direction of the nozzle plate A second flow path that is communicating the second pressure chamber with the communication flow path and that extends in the third direction A third flow path that is communicating the third pressure chamber with the communication flow path and that extends int eh third direction A fourth flow path that is communicating the fourth pressure chamber with the communication flow path and that extends in the third direction (Figures 4, 6; as shown in Figure 6, the communication channel Ra1 disclosed flow paths for each of the pressure chambers; Paragraphs 0090-0091) Regarding claim 11, a liquid ejecting head comprising a nozzle plate (51) on which a nozzle configured to eject a liquid is formed (Figure 3; Paragraph 0041) First and second pressure chambers arranged side by side in a first direction (Figures 2, 4; C_1, C_2; Paragraphs 0035, 0057-0058) Third and fourth pressure chambers arranged side by side in the first direction (Figures 2, 4; C_3, C_4; Paragraph 0035, 0057-0058) A communication flow path (NF_1) extending along the nozzle plate, coupled to the nozzle, and communicating with the first to fourth pressure chambers (Figure 4; Paragraph 0057) A first common liquid chamber (R1) communicating with the first and second pressure chambers (Figure 4; Paragraph 0056) A second common liquid chamber (R2) communicating with the third and fourth pressure chambers (Figure 4; Paragraph 0056) The first and second pressure chambers and the third and fourth pressure chambers are shifted in a second direction orthogonal to the first direction (Figure 4) A length of a part of the communication flow path in the second direction between the first pressure chamber and the third pressure chamber is equal to or less than a width of the communication flow path in the first direction at a potion overlapping the nozzle in plan view seen toward the nozzle plate (Figure 4) Only a part of a length of the communication flow path in the second direction needs to be equal to or less than a width of the communication flow path in the first direction, which will meet the claim limitation. Refer to figure below.
