Office Action

§102 §103
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 . Response to Arguments Applicant's arguments filed 8/14/26 have been fully considered but they are not persuasive. The applicant states that Lee fails to disclose that a first part is farther away from a long side of the substrate than a second part. The examiner respectfully disagrees. Lee discloses a first part 33 and a second part 34, where the first is disposed inward of the substrate on the long side and the short side, and the second part 34 sits outside of the first part 33 on the long side and the short side. The first part 33 will always be farther away from any edge of the substrate than the second part 34, so Lee does disclose that: The first being at a position at a first distance from the long side of the substrate in the second direction, and the second part being at a position at a second distance from the long side of the substrate in the second direction (Lee, Figure 13, the first part 33 is farther away from the long edge than the second part 34), wherein The first distance is greater than the second distance (Lee, Figure 13, the first part 33 is farther away from the long edge than the second part 34).

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. Claims 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Koyama et al (US Publication No.: US 2022/0171308 A1 of record, “Koyama”). Regarding Claim 19, Lee discloses the light emitting device according to claim 1. Lee fails to disclose a photosensitive member; a charging section which charges the photosensitive member; an exposure section and which forms an electrostatic latent image on a surface of the photosensitive member; a development section which develops the electrostatic latent image; and a transfer section which transfers the developed image to a recording medium. However, Koyama discloses an image forming apparatus (Koyama, Figure 1; Paragraph 0025), comprising a photosensitive member (Koyama, Figure 1, photosensitive member 102); a charging section which charges the photosensitive member (Koyama, Figure 1, charging section 107); an exposure section and which forms an electrostatic latent image on a surface of the photosensitive member (Koyama, Figure 1, exposure section 106); a development section which develops the electrostatic latent image (Koyama, Figure 1, development section 108); and a transfer section which transfers the developed image to a recording medium (Figure 1, transfer section 110/111; Paragraph 0026). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the light emitting device as disclosed by Lee to be part of an image forming apparatus as disclosed by Koyama. One would have been motivated to do so for the purpose of optimizing the image forming process (Koyama, Paragraphs 0025-0026). Regarding Claim 20, Lee discloses the light emitting device according to claim 8. Lee fails to disclose a photosensitive member; a charging section which charges the photosensitive member; an exposure section and which forms an electrostatic latent image on a surface of the photosensitive member; a development section which develops the electrostatic latent image; and a transfer section which transfers the developed image to a recording medium. However, Koyama discloses an image forming apparatus (Koyama, Figure 1; Paragraph 0025), comprising a photosensitive member (Koyama, Figure 1, photosensitive member 102); a charging section which charges the photosensitive member (Koyama, Figure 1, charging section 107); an exposure section and which forms an electrostatic latent image on a surface of the photosensitive member (Koyama, Figure 1, exposure section 106); a development section which develops the electrostatic latent image (Koyama, Figure 1, development section 108); and a transfer section which transfers the developed image to a recording medium (Figure 1, transfer section 110/111; Paragraph 0026). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the light emitting device as disclosed by Lee to be part of an image forming apparatus as disclosed by Koyama. One would have been motivated to do so for the purpose of optimizing the image forming process (Koyama, Paragraphs 0025-0026). 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).
