Office Action

§102 §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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Specification The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claim 5 and 9 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 5 recites “the spring is located on an inner side with respect to the contact member in the rotation axis direction”, while claim 9 recites “the holder includes a supporting portion supporting the head frame on an inner side with respect to the contact face in the rotation axis direction” which are not described in the specification. Claim Rejections - 35 USC § 102/103 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. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1-3, 5, 7, 9-12, 14 and 16 is/are rejected under 35 U.S.C. 102(a)(1) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over US 20140232803 to Kobayashi.

Claim(s) 4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kobayashi as applied to claim 3 above, and further in view of US 20020018666 to Noda. Regarding Claim 4, Kobayashi discloses the image forming apparatus according to claim 3, but is silent regarding the photosensitive drum assembly includes a ground spring arranged to contact the metal shaft and the inner circumferential surface of the photosensitive drum. Noda discloses the photosensitive drum assembly includes a ground spring arranged to contact the metal shaft and the inner circumferential surface of the photosensitive drum (Figs. 11 and 41-42, flexible metal grounding plate 118 (plate spring) contacting conductive rod member 119 (shaft) and bites into internal surface 7d1 of drum cylinder 7d; ¶¶ 0242]-[0248]). It would have been obvious to one of ordinary skill in the art before the effective filing of the application to modify the invention of Kobayashi by providing the photosensitive drum assembly includes a ground spring arranged to contact the metal shaft and the inner circumferential surface of the photosensitive drum as in Noda in order to provide for a drum grounding path through which the charge remaining in the photosensitive drum is discharged to the apparatus main assembly. Claim(s) 6 and 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kobayashi as applied to claims 1 and 9 above, and further in view of US 20090202272 to Nakashima. Regarding Claims 6 and 15, Kobayashi discloses the image forming apparatus according to claims 1 and 9, and further discloses the exposure head is located at the retracted position under a condition of a user operation and the drum unit is attachable to or detachable from the housing under the condition of the user operation (¶ [0085]). However, Kobayashi does not disclose a cover configured to open or close an opening formed in the housing, wherein the exposure head is located at the retracted position under a condition where the cover is open, and the drum unit is attachable to or detachable from the housing through the opening under the condition where the cover is open. Nakashima discloses a cover configured to open or close an opening formed in the housing (Figs 1-2, and 5, upper cover 12 capable of being rotated open and closed on top of main casing 10; ¶¶ [0023], [0052]-[0054]), wherein the exposure head is located at the retracted position under a condition where the cover is open (Figs 1-2, and 5, LED units 40 in retracted position with opening of upper cover 12; ¶¶ [0023], [0052]-[0054]), and the drum unit is attachable to or detachable from the housing through the opening under the condition where the cover is open (Figs 1-2, and 5, photosensitive drums 53 insertable with LED units 40 in retracted position with opening of upper cover 12; ¶¶ [0023]-[0028], [0052]-[0059]). It would have been obvious to one of ordinary skill in the art before the effective filing of the application to modify the invention of Kobayashi by providing a cover configured to open or close an opening formed in the housing, wherein the exposure head is located at the retracted position under a condition where the cover is open, and the drum unit is attachable to or detachable from the housing through the opening under the condition where the cover is open. Nakashima discloses a cover configured to open or close an opening formed in the housing as in Noda in order to provide for a well-known alternative user operation for separating the LEDs and the drum. See, e.g., "substitution of art-recognized equivalents" as discussed in MPEP 2144.06II "An express suggestion to substitute one equivalent component or process for another is not necessary to render such substitution obvious. In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982)." Claim(s) 8 and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kobayashi as applied to claims 7 and 16 above, and further in view of US 20110064462 to Abe. Regarding Claims 8 and 17, Kobayashi discloses the image forming apparatus according to claims 7 and 16, but does not disclose the bearing is a sleeve bearing. Abe discloses the bearing is a sleeve bearing (Figs. 6-7 and 13, drum flange 81 inserted inside sleeve 92 of bearing 90/91; ¶¶ (0068]-[0072]). It would have been obvious to one of ordinary skill in the art before the effective filing of the application to modify the invention of Kobayashi by providing the bearing is a sleeve bearing as in Abe in order to provide for improved drum alignment. Claim(s) 13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kobayashi as applied to claim 9 above, and further in view of US 20130259521 to Sugiyama. Regarding Claim 13, Kobayashi discloses the image forming apparatus according to claim 3, and further discloses the frame 50 has through-hole 155 for supporting supportable portions 147 of holder 145 (¶¶ 0057]-[0060]). However, Kobayashi does not disclose the head frame includes a through hole, in which the contact member is inserted, and the contact member is supported by the head frame by being inserted in the through hole. Sugiyama discloses the head frame includes a through hole, in which the contact member is inserted, and the contact member is supported by the head frame by being inserted in the through hole (Figs. 9-10, roller 240 supported by rotation shaft 250 which is supported by bearing hole 222 formed on lower portion of extended part 220 of supporting frame 200; ¶¶ [0052], [0078], [0084]-[0087]). It would have been obvious to one of ordinary skill in the art before the effective filing of the application to modify the invention of Kobayashi by providing the head frame includes a through hole, in which the contact member is inserted, and the contact member is supported by the head frame by being inserted in the through hole as in Sugiyama in order to provide for a well-known alternate mounting means for a contact member.
