CTNF 19/014,952 CTNF 83061 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. Priority 02-26 AIA Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statement (IDS) submitted on 01/09/2025 is being considered by the examiner. Specification 06-11 AIA The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. Claim Objections 07-29-01 AIA Claim s 2-6, 8-11 are objected to because of the following informalities: - In claims 2, 3, 4, 5, and 6 in line 1, cancel the term “A liquid ejection device” and replace with “The liquid ejection device” to properly refer to the liquid ejection device in the corresponding parent claim. - In claims 8, 9, 10, and 11 in line 1, cancel the term “A liquid ejection system” and replace with “The liquid ejection system” to properly refer to the liquid ejection device in the corresponding parent claim . Appropriate correction is required. 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 Claim s 1, 6, and 7 are rejected under 35 U.S.C. 102( a)(1 ) as being anticipated by Nagashima et al. (US 2014/0340453) . Regarding claim 1, Nagashima et al teaches a liquid ejection device (fig.1) being coupled to a mounting unit (for instance 65 in figs.7,5, and/or 5a in fig.20) on which a liquid accommodation body (7 figs.20,10,3) configured to accommodate a liquid is mounted, the liquid ejection device comprising: an ejection unit (22 fig.1) configured to eject the liquid; a device flow path (70 including 702, 24 figs.8,1) extending from the ejection unit; and a reception unit (710 figs.8,5) configured to receive the liquid, wherein the device flow path includes a coupling unit (706 figs.7,5,3) to be coupled to the mounting unit (65 in figs.7, and/or 5a in fig.20), and the reception unit (710) is positioned vertically below the coupling unit (figs.5,7,8). Regarding claim 6, Nagashima et al further teaches a retaining unit (for instance 45 figs.22) configured to retain the coupling unit, wherein the coupling unit (706) is configured to move between a coupling position (figs.3,23,24) at which the coupling unit is coupled to the mounting unit (for instance 5a in fig.20) and a separation position (fig.22) at which the coupling unit is separated from the mounting unit (for instance 5a in fig.20), and the retaining unit retains the coupling unit (706) positioned at the separation position (fig.22). Regarding claim 7, Nagashima et al further teaches a liquid ejection system comprising: the liquid ejection device according to claim 1; and the mounting unit (for instance 65 in figs.7,5, and/or 5a in fig.20) . 07-15 AIA Claim 1 is rejected under 35 U.S.C. 102( a)(1 ) as being anticipated by Hirai et al. (US 2022/0072865) . Regarding claim 1, Hirai et al teaches a liquid ejection device (figs.1,2) being coupled to a mounting unit (14) on which a liquid accommodation body (21) configured to accommodate a liquid is mounted, the liquid ejection device comprising: an ejection unit (38 fig.2) configured to eject the liquid; a device flow path (27 including 42,41,43 fig.2) extending from the ejection unit; and a reception unit (medium S fig.2) configured to receive the liquid (medium S receives the ejected liquid), wherein the device flow path (27 including 42,41,43 fig.2) includes a coupling unit (43 fig.2) to be coupled to the mounting unit (fig.2), and the reception unit (medium S fig.2) is positioned vertically below the coupling unit (43) (figs.2,1) . Allowable Subject Matter 12-151-08 AIA 07-43 12-51-08 Claim s 2-5, 8-11 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
