DERRICK, JULIA HEANEY, and LILAN REN, Administrative Patent Judges. HEANEY, Administrative Patent Judge. DECISION ON APPEAL Appellant1 requests review pursuant to 35 U.S.C. § 134(a) of a decision of the Examiner rejecting claims 1, 3—17, and 20—212 of Application 12/891,712. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. 1 Appellant identifies the real party in interest as Prysm, Inc. Appeal Brief dated Mar. 12, 2015 (“App. Br.”), 3. 2 Final Rejection dated Sept. 11, 2014 (“Final Act.”), 2—9. This Decision also refers to the Examiner’s Answer dated Aug. 6, 2015 (“Ans.”), and the Reply Brief dated Oct. 2, 2015 (“Reply Br.”). Appeal 2016-000293 Application 12/891,712 BACKGROUND The subject matter on appeal relates to a two-dimensional scanning projector which enlarges and projects an image generated by causing a light beam emitted from a light source to scan in two dimensions. App. Br. 5. Appellant’s Specification (“Spec.”) describes that such a projector can save space by tilting the projection such that the optical axis is not orthogonal to the screen. Spec. 1 3. A tilted projection, however, introduces distortion of the image projected on the screen. Spec. 14. Appellant seeks to compensate for the reduction in image quality associated with a tilted projection. Spec. 17. Claim 1, reproduced below from the Claims Appendix of the Appeal Brief, is illustrative of the subject matter on appeal: 1. A two-dimensional scanning projector for causing a light beam emitted from each of a plurality of light sources to scan in a first direction and in a second direction, orthogonal to the first direction, thereby projecting a two-dimensional image onto a screen, the projector comprising: a first deflector for deflecting the light beam in the first direction; a scanning optical system arranged between the first deflector and the screen, the scanning optical system comprising optical components which are collinear with each other and define an optical axis of the scanning optical system, each of the optical components having a power rotationally symmetrical with respect to the optical axis; wherein the optical axis intersects a plane in which the screen lies, and a center of the screen is at a location shifted in the second direction relative to the intersection of the optical axis and the plane; wherein the first deflector has a rotation axis located in a plane including the optical axis and the second direction and 2 Appeal 2016-000293 Application 12/891,712 which is inclined by a first angle with respect to the second direction; wherein the first deflector is located whereby the light beam, emitted from the light source and in the plane including the optical axis and the second direction, forms a chief ray of the projected image and is obliquely incident on the first deflector at a second angle with respect to the optical axis; a second deflector which is located between the light source and the first deflector for deflecting the light beam in the second direction; and wherein the projector is configured such that light beams emitted from each of the plurality of light sources form beam spots on the screen. THE REJECTIONS 1. Claims 1, 3—4, 6, 7, 9-12, 14, 15, 17, 20, and 21 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Iizuka,3 Ishihara,4 and Amada.5 Final Act. 2. 2. Claims 5 and 13 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Iizuka, Ishihara, Amada, and Takeuchi.6 Final Act. 8. 3. Claims 8 and 16 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Iizuka, Ishihara, Amada, and Nakamura.7 Final Act. 9. 3 Iizuka, US 2002/0018273 Al, pub.

Dec. 10, 1996 (“Nakamura”). 3 Appeal 2016-000293 Application 12/891,712 DISCUSSION Appellant argues for patentability of the appealed claims on the basis of limitations that are common to independent claims 1 and 10, and does not separately argue any of the other appealed claims. App. Br. 5—13. We therefore focus our discussion on claims 1 and 10 as argued by Appellant; all dependent claims will stand or fall with the claim from which they depend. 37 C.F.R. § 41.37(c)(l)(iv) (2013). The Examiner relies on Iizuka as disclosing a two-dimensional scanning projector comprising the optical components recited in claim 1, except that Iizuka does not teach that “a center of the screen is at a location shifted in the second direction relative to the intersection of the optical axis and the plane” or that “light beams emitted from each of the plurality of light sources form beam spots on the screen.” Claims Appx; Final Act. 2-4 (providing citations to Iizuka). The Examiner relies on Ishihara as disclosing a two-dimensional scanning projector having a center of the screen (Ishihara Figs. 1 and 4: 68) at a location shifted in a second/longitudinal direction {Id., y-direction) orthogonal to the first/lateral direction {Id., x-direction) relative to the intersection of an optical axis (Ishihara Fig. 5: Ax) and the plane of screen 6. Final Act. 4. The Examiner determines it would have been obvious to a person of ordinary skill in the art to modify Iizuka’s projector by shifting the center of the screen as taught by Ishihara, in order to reduce the appearance of ghost light on the screen. Id., citing Iizuka Figs. 4B-4C. The Examiner further determines that although neither Iizuka nor Ishihara teach a plurality of light sources, it would have 8 Fabels to elements are presented in bold font, regardless of their presentation in the original document. 4 Appeal 2016-000293 Application 12/891,712 been obvious to a person of ordinary skill in the art to provide a plurality of light sources, as taught by Amada, in order to provide a color image. Final Act. 4—5 (providing citations to Amada). Appellant argues that neither Iizuka nor Ishihara discloses two-dimensional scanning using a plurality of light sources to project a two-dimensional image onto a screen. App. Br. 7—9. Appellant further argues that the Examiner’s proposed combination of Iizuka, Ishihara, and Amada does not teach “optical components that are collinear with each other and define an optical axis of the scanning optical system and also where the optical axis is shifted from the center of the screen.” Id. 9—11. To prevail in an appeal to this Board, Appellant must adequately explain or identify reversible error in the Examiner’s rejection. See 37 C.F.R. § 41.37(c)(l)(iv) (2012); see also In re Jung, 637 F.3d 1356, 1365— 66 (Fed. Cir. 2011) (explaining that even if the Examiner fails to make a prima facie case, it has long been the Board’s practice to require Appellants to identify the alleged error in the Examiner’s rejection); In re Chapman, 595 F.3d 1330, 1338 (Fed. Cir. 2010) (“[T]he burden of showing that the error is harmful normally falls upon the party attacking the agency’s determination.” (Quoting Shinseki v. Sanders, 556 U.S. 396, 409 (2009))). Appellant’s arguments are not persuasive of reversible error because they are not responsive to the rejection as set forth by the Examiner, and argue the references individually although the rejections are based on combination of the references. See In re Keller, 642 F.2d 413 (CCPA 1981) (arguing against individual references cannot overcome a rejection based on a combination of the references). For example, although Appellant argues that Iizuka and Ishihara do not disclose a plurality of light sources, the Examiner does not rely on those references for teaching a plurality of light 5 Appeal 2016-000293 Application 12/891,712 sources, but rather relies on Amada. Ans. 3. Moreover, Appellant does not dispute that Amada teaches a plurality of light sources, nor do they point us to an error in the Examiner’s reasoning for combining Amada with Iizuka and Ishihara. Generally App. Br.; Reply Br. Appellant’s argument that none of the references alone combines collinear optical elements that define an optical axis with an optical axis that is shifted from the center of the screen is not responsive to the rejection because it does not address the grounds for the rejection. App. Br. 9-11. The Examiner relies on Iizuka as teaching collinear elements along the optical axis, and Ishihara as teaching a screen that is shifted from the optical axis. Ans. 3^4. Appellant does not direct us to a reversible error in the Examiner’s reasoning for combining Iizuka and Ishihara. Reply Br. 2—5. Accordingly, we are not persuaded of reversible error by Appellant’s arguments. SUMMARY We affirm the rejections of claims 1, 3—17, and 20-21. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a). AFFIRMED 6 Copy with citationCopy as parenthetical citation
