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 . Information Disclosure Statement The information disclosure statements (IDS) submitted on 04/25/2025; 03/14/2024 and 10/24/2023 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner. Specification The disclosure is objected to because of the following informalities: Foreign Application data is missing from the specification. PNG media_image1.png 79 234 media_image1.png Greyscale Appropriate correction is required and respectfully requested. 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)(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. Claims 1-14 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Nishii et al. (US PAP 2022/0313199 A1). The applied reference has a common applicant with the instant application. Based upon the earlier effectively filed date of the reference, it constitutes prior art under 35 U.S.C. 102(a)(2). This rejection under 35 U.S.C. 102(a)(2) might be overcome by: (1) a showing under 37 CFR 1.130(a) that the subject matter disclosed in the reference was obtained directly or indirectly from the inventor or a joint inventor of this application and is thus not prior art in accordance with 35 U.S.C. 102(b)(2)(A); (2) a showing under 37 CFR 1.130(b) of a prior public disclosure under 35 U.S.C. 102(b)(2)(B) if the same invention is not being claimed; or (3) a statement pursuant to 35 U.S.C. 102(b)(2)(C) establishing that, not later than the effective filing date of the claimed invention, the subject matter disclosed in the reference and the claimed invention were either owned by the same person or subject to an obligation of assignment to the same person or subject to a joint research agreement. With respect to claim 1, Nishii et al. teaches a radiation imaging system comprising (see abstract; Figs. 1-14; paragraphs 0053, 0075-0078, 0086, 0097, 0102-0103 and 0117): PNG media_image2.png 531 591 media_image2.png Greyscale a radiation imaging apparatus (1) including a conversion unit (300) comprising detector pixels (101) each including conversion elements (102) configured to generate electric charge in response to irradiation with radiation (see Figs. 1 and 2; paragraph 0053), PNG media_image3.png 527 788 media_image3.png Greyscale and a transmission unit (225; 403) configured to transmit, based on the electric charge generated by the conversion unit and a target value, a signal related to control of irradiation with radiation to an external apparatus (see Fig. 5; paragraph 0075); and a control apparatus (310) including a dose index generating unit (502) configured to generate a target dose index value that is based on the target value (see Fig. 6; paragraph 0086), and a dose index value that is based on information regarding electric charge, the information being acquired from the radiation imaging apparatus, an allowable range setting unit (see paragraph 0102) configured to set an allowable range of the target dose index value, and a determination unit (501) configured to determine whether the dose index value is within the allowable range (see Figs. 5 and 6; paragraphs 0075, 0086 and 0102).
