Office Action

§103 §112
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 . 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. Claim Interpretation The claims have been amended to avoid a rebuttal presumption that the claim elements are to be treated in accordance with 35 U.S.C. 112(f). Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 5-7 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 5 recites inter alia, “the second substrate having mounted thereon a second light-emitting element arranged to emit light onto the surface of the photosensitive member from a side of the other end side of the photosensitive member”. There is insufficient antecedent basis for the limitation the other end in the claim. For the purpose of examination over prior art, this limitation is interpreted as “the second substrate having mounted thereon a second light-emitting element arranged to emit light onto the surface of the photosensitive member from a side of the another end side of the photosensitive member”. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 5-7 is/are rejected under 35 U.S.C. 103 as being unpatentable over JP 2010-160185 to Watanabe et al. (cited in IDS dated 09/03/2024) in view of US 10,094,739 to Hayashi. Regarding claim 5, Watanabe teaches an image forming apparatus (100, Fig.1) comprising: a rotatable photosensitive member (1); a charging roller (2) configured to charge the photosensitive member; an exposure light source (3) configured to emit light to expose the photosensitive member charged by the charging roller and to form a latent image; a developing roller (4) configured to develop the latent image with tone; a transfer roller (5) configured to transfer a toner image developed and formed by the developing roller to a recording material; a pre-exposure unit (8) configured to expose a surface of the photosensitive member after the toner image is transferred to the recording material and before being charged by the charging roller; and a controller (not shown) configured to control the pre-exposure unit, wherein the pre-exposure unit includes a first substrate disposed adjacent to one end of the photosensitive member with respect to a longitudinal direction of the photosensitive member, the first substrate having mounted thereon a first light-emitting element arranged to emit light onto the surface of the photosensitive member from a side of the one end of the photosensitive member toward a vicinity of a center of the photosensitive roller with respect to the longitudinal direction; and a second substrate disposed adjacent to another end of the photosensitive member, the second substrate having mounted thereon a second light-emitting element arranged to emit light onto the surface of the photosensitive member from a side of the another end side of the photosensitive member toward the vicinity of the center of the photosensitive roller with respect to the longitudinal direction is mounted (Fig.3, pre-exposure device 8 has a red diode fixed to the base and is arranged on both sides in the longitudinal direction of the drum 1). wherein the controller is configured to selectively execute a first mode and a second mode, wherein, in the first mode, the controller controls the first light emitting light-emitting element and the second light-emitting element to emit the light to expose the surface of the photosensitive member. Watanabe is silent about the controller determining a normal or failure state of the first light-emitting element and the second light-emitting element based on a detected electromotive voltage. Hayashi discloses a light-emitting apparatus 100 that emits light at a rating by causing first laser diode 161 and second laser diode 162 to alternately oscillate, and detectors 107 alternately detect an electromotive force of first laser diode 161 in a non-radiation state, that is, not radiating laser light, and an electromotive force of second laser diode 162. Subsequently, when the electromotive force of one of the laser diodes becomes less than or equal to a predetermined third threshold, detectors 107 may inform an abnormality as status information, and controller 160 which has received the status information may interrupt the radiation of laser light by each of two radiation apparatuses 106 (Fig.6, col. 8 lines 51-63). It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Hayashi into the apparatus of Watanabe such that, wherein, in the second mode, the controller: controls the first light-emitting element to emit light; detects an electromotive voltage generated by the second light-emitting element when the second light-emitting element receives the light emitted by the first light-emitting element; determines, based on the detected electromotive voltage, whether the first light- emitting element is in a normal state or in a failure state; controls the second light-emitting element to emit light; detects an electromotive voltage generated by the first light-emitting element when the first light-emitting element receives the light emitted by the second light-emitting element; and determines, based on the detected electromotive voltage, whether the second light-emitting element is in a normal state or in a failure state, for at least the purpose of enabling diagnostics of the apparatus without the need for additional components. The modification above further renders obvious: (claim 6) The image forming apparatus according to claim 5, wherein the controller includes an input/output port to which each of the first light-emitting element and the second light-emitting element is connected, and wherein the controller switches the input/output port to operate as an output port when the first light-emitting element and the second (claim 7) The image forming apparatus according to claim 6, wherein each of the first light-emitting element and the second Response to Arguments Applicant’s arguments with respect to claim(s) 5-7 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
