Office Action

§102
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 . Priority The instant Application claims benefit as a continuation-in-part of the prior application PCT/CN2022/142654 under 35 U.S.C. 119e, 120, 121, 365(c) or 386(c). The requirements of 35 U.S.C. 120 and 37 CFR 1.78 are met to the extent defined in MPEP 201.08, and therefore the instant Application receives the benefit to the filing date of 3/1/2016. Furthermore, acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed on 3/13/25, the requirements 35 U.S.C. 119 (a)-(d) are met. Information Disclosure Statement The references cited on a Form PTO 1449 have been considered. Specification The specification has been checked to the extent necessary to determine the presence of all possible minor errors. However, the applicant's cooperation is requested in correcting any errors of which applicant may become aware in the specification. Claim Rejections - 35 USC § 102 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. 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) 1 and 9 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ishii et al. (U.S. 2011/0187793 A1). Ishii et al. disclose the following claimed limitations: Regarding independent Claim 1, an inkjet printhead assembly (20, §§0033-0054 and Figs. 1-6) having a deflection angle (best seen in Fig. 2), comprising: an inkjet printhead carrier (30, §§0036-0038 and Figs. 1-6); and a plurality of inkjet printheads (40, §§0036-0038 and Figs. 1-6) mounted on the inkjet printhead carrier, the plurality of inkjet printheads being distributed in several rows (40, §0039 and Figs. 1-6) in parallel on the inkjet printhead carrier, and the inkjet printheads in the two adjacent rows being in staggered and overlapped arrangement (best seen in Figs. 1, 3), wherein the plurality of the inkjet printheads are mounted obliquely relative to the inkjet printhead carrier, and the plurality of the inkjet printheads are arranged around an arc-shaped printing surface; lower surfaces of the plurality of the inkjet printheads are combined to form a recessed inkjet surface, and each surface of the recessed inkjet surface is tangential with the arc-shaped printing surface (best seen in Fig. 5). Regarding Claim 9, a roller (10, §§0033-0035 and Figs. 1-2, 5), configured to wind and deliver a printing medium (S, §0035 and Figs. 2, 5); a linear movement assembly (11, 31C, 32C, 36, 37, §0048 and Fig. 6); and the inkjet printhead assembly, which is driven by the linear movement assembly to adjust a distance between the inkjet printhead assembly and a surface of the roller (§0048 and Figs. 2, 5-6). Allowable Subject Matter Claims 2-8 and 10 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. The following is a statement of reasons for the indication of allowable subject matter: the primary reason for indicating allowable subject matter of claims 2-8 is the inclusion of the limitations of an inkjet printhead assembly including wherein the inkjet printhead carrier has a first reference line which points to a circle center of the arc-shaped printing surface, nozzle orifices of each of the inkjet printheads have a second reference line which points to an inkjet direction of the nozzle orifices, an included angle between the first reference line and the second reference line is a deflection angle [Symbol font/0x6A], and the inkjet printheads are mounted obliquely at the deflection angle y relative to the first reference line, and wherein a calculation formula for the deflection angle [Symbol font/0x6A] is = tan - 1 ⁡ L + H tan ⁡ α R + H ; L refers to a distance between the nozzle orifices and the first reference line; H refers to a height from the inkjet printhead carrier to the arc-shaped printing surface; α refers to an included angle between a movement direction of the nozzle orifices and the first reference line; and R refers to a radius of the arc-shaped printing surface. It is these limitations found in the claims, as it is claimed in the combination of that has not been found, taught or suggested by prior art of record, which makes these claims allowable over the prior art. The primary reason for indicating allowable subject matter of claims 2-8 is the inclusion of the limitations of an inkjet printhead assembly including wherein four inkjet printhead assemblies and three linear movement assemblies are included, the four inkjet printhead assemblies surround the roller in sequence from left to right at intervals and are arranged symmetrically relative to the fourth reference line, and the three linear movement assemblies surround the roller in sequence from left to right at intervals and are arranged symmetrically relative to the fourth reference line; the inkjet printhead assembly on the left side is fixedly connected to the linear movement assembly on the left side, the inkjet printhead assembly on the right side is fixedly connected to the linear movement assembly on the right side, and the two inkjet printhead assemblies in the middle are simultaneously connected to the linear movement assembly in the middle; and each linear movement assembly drives the respective inkjet printhead assembly independently to adjust the distance between the respective inkjet printhead assembly and the surface of the roller. It is these limitations found in the claims, as it is claimed in the combination of that has not been found, taught or suggested by prior art of record, which makes these claims allowable over the prior art.
