Claims 1, 9, 10, and 11 are illustrative of the claims on appeal and are reproduced below from the Claims Appendix to the Appeal Brief:12 1. A lithographic printing press comprising: (a) a plate cylinder mounted with a lithographic printing plate comprising on a substrate a photosensitive layer soluble or dispersible in ink and/or fountain solution and capable of hardening upon exposure to a laser having a wavelength selected from 200 to 1200 nm; (b) an exposure means capable of emitting said laser to imagewise expose said mounted plate; and 4 Onuma et al., US 6,543,348 B2 issued Apr. 8, 2003 (“Onuma”). 5 Mori, US 2002/0088360 A1 published July 11, 2002 (“Mori”). 6 Dupertuis et al., EP 1764215 A1, published Mar. 21, 2007 (“Dupertuis”). 7 DeMoore, US 5,540,152 issued July 30, 1996 (“DeMoore”). 8 Goodin et al., US 2004/0038152 A1, published Feb. 26, 2004 (“Goodin”). 9 Blake et al., US 6,726,433 B1 issued Apr. 27, 2004 (“Blake”). 10 Fuhrmann et al., US 5,413,043 issued May 9, 1995 (“Fuhrmann”). 11Williams, US 6,539,859 B2, issued Apr. 1, 2003 (“Williams”). 12 We will limit our discussion to independent claim 1 and dependent claims 9, 10, and 11. Appellant does not separately argue the patentability of dependent claims 2–5, 7, 8, and 12. App. Br. 8–17. In accordance with 37 C.F.R. § 41.37(c)(1)(iv), claims 2–5, 7, 8 will stand or fall together with independent claim 1 from which they depend and claim 12 will stand or fall together with claim 11. Appeal 2015-006316 Application 12/176,377 3 (c) an inking means comprising an inking unit or both an inking unit and a fountain unit; (d) wherein said press is in a pressroom having white room light; and at least said plate mounted on the plate cylinder is within a compartment shielded with covers and other press parts so that, when the covers are fully closed and when there is no light source turned on within said compartment, the intensity of the light at each wavelength below 450 nm around the plate cylinder is less than 10% of the intensity of the room light around the outer top surface of the press at such wavelength; wherein said covers include certain areas which are non- transparent to any white light and other areas which are only transparent to a yellow or red light. 9. The lithographic press of claim 1 further comprising a light- tight cassette containing at least one lithographic plate for automatically loading the lithographic plate onto the plate cylinder. 10. The lithographic press of claim 1 wherein the lithographic plate is in the form of continuous web with one end rolled out from a fresh roll of plate in a light-light [sic, light-tight] cartridge and the other end rolled into a used roll in a second cartridge, both cartridges are installed within the plate cylinder with the portion of the plate between the cartridges being mounted on the plate cylinder, and said plate is capable of unwinding from the light-tight cartridge and winding into the second cartridge at the beginning of a printing operation. 11. The lithographic press of claim 10 wherein said plate cylinder is mounted with 2 sets of plates, the first plate is mounted on the plate cylinder surface from about 0° to about 180° of the rotating direction of the cylinder with the corresponding fresh and used plate rolls installed within the cylinder, and the second plate is mounted on the same plate cylinder surface from about 180° to about 360° (0°) of the rotating direction of the cylinder with the corresponding fresh and used plate rolls installed within the cylinder. Claim 1 Regarding claim 1, the Examiner makes the following findings of fact which are supported by a preponderance of the evidence on this record: Appeal 2015-006316 Application 12/176,377 4 Onuma establishes that at the time of the invention, it was known in the lithographic printing press art to mount a lithographic plate on a plate cylinder, expose the mounted plate with a laser beam to print an image on the plate mounted on the plate cylinder, and shield the plate cylinder compartment with covers. Final Act. 2–3 (citing Onuma Figs. 3, 6, items 10, 21, 39, 40, 77, 3:1–2). Mori evidences that at the time of Appellant’s invention, it was known in the art to use as a printing plate in a printing press a photosensitive layer soluble or dispersible in ink and/or fountain solution water soluble or dispersible overcoat on the photo sensitive layer capable of hardening upon exposure to an infrared laser which has a wavelength in the range from 200 to 1200 nm. Id. at 3 (citing Mori ¶¶ 54, 71, 92). Dupertuis evidences that at the time of the invention, it was known in the art to use a cover with a removable window for viewing a cylinder under room light to inspect the printing process during operation. Id. at 3–4 (citing Dupertuis ¶ 22, item 72). Goodin evidences that at the time of the invention, it was known to handle undeveloped photosensitive printing plates in yellow light rooms or conditions to prevent exposure to incidental white light or sunlight. Id. at 4 (citing Goodin ¶ 8). Based on the above findings of fact, the Examiner concludes it would have been obvious to one of ordinary skill in the art: to modify the printing plate of Onuma to include on a substrate a photosensitive layer soluble or dispersible in ink and/or fountain solution capable of hardening upon exposure to a laser having a wavelength selected from 200 to 1200nm as taught by Mori in order to manufacture a printing plate for use in a printing press. Id. at 3 (citing Mori ¶ 92). The Examiner reasons that it would have been obvious to modify the cover of the printing press disclosed by Onuma based on Dupertuis’ Appeal 2015-006316 Application 12/176,377 5 teaching “to include at least one removable window so the operator could visually inspect the printing process during operation.” Id. at 3–4. The Examiner further finds that: it would have been obvious to one of ordinary skill in the art at the time of the invention to modify the transparent areas of the cover taught by the combination of Onuma, Mori and Dupertuis such that these transparent areas were only transparent to a yellow-red light source in order to prevent incidental exposure to white light that may spontaneously harden the photosensitive layer of the printing plate as suggested in Goodin (pg. 1, par [0008]). Id. at 4. Appellant does not dispute the above findings of fact with respect to Onuma, Mori, Dupertuis, and Goodin, but argues that Onuma, Mori, and Goodin are all designed for plates which are safe under white room light and do not teach press covers with certain areas non-transparent to any white light or only transparent to yellow or red light. App. Br. 8–10. Appellant further contends that Dupertuis is directed to an intaglio printing press which is different from a lithographic printing press in that it does not use a lithographic printing plate and it also does not teach press covers with certain areas non-transparent to any white light or only transparent to yellow or red light. Id. at 9. In the Reply Brief, Appellant asserts without citation that it provided arguments “based on the analysis of each reference as well as the combination of all references.” Reply Br. 2. Appellant also reiterates its argument that “[b]ecause the plates of Onuma et al, Mori, and DeMoore are safe under white light, there is Appeal 2015-006316 Application 12/176,377 6 no need to handle the plates of Onuma et al, Mori, and DeMoore under the low light or yellow light [room] or conditions of Goodin et al.” Id. at 3–4.13 We are not persuaded by Appellant’s argument that the combination of Onuma, Mori, Dupertuis, and Goodin does not disclose all of the elements of claim 1. Appellant’s argument distinguishing the operation of Dupertuis’ press is unpersuasive because, in a determination of obviousness, a reference may be relied upon for all that it would have reasonably suggested to one having ordinary skill in the art. Merck & Co. v. Biocraft Labs., 874 F.2d 804, 807 (Fed. Cir. 1989). “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of those references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425 (CCPA 1981). Appellant’s arguments against the combination of the references are unpersuasive because Appellant distinguishes each of the cited prior art references separately and disputes the propriety of their combination based on whether their disclosed features can be bodily fused together. Appellant does not dispute the Examiner’s reasons for combining the references to modify Onuma. The Examiner provides a persuasive reason for combining each reference to modify Onuma’s printing press based on the teachings of the references themselves. Each of Onuma, Mori, and Goodin exposes the plate to laser irradiation for forming an image and Dupertuis explicitly states that its teachings are not limited to a cylinder of an intaglio printing press. Dupertuis ¶ 1. Additionally, Appellant does not dispute the Examiner’s finding that Onuma teaches a plate: 13 Appellant also refers to DeMoore and Blake in the Reply Brief, however, the Examiner did not rely on DeMoore and Blake in the rejection as applied to claim 1. Reply Br. 2–4: Final Act. 2–5. Appeal 2015-006316 Application 12/176,377 7 within a compartment shielded with covers and other press parts so that, when the covers are fully closed and when there is no light source turned on within said compartment, the intensity of the light at each wavelength below 450 nm around the plate cylinder is less than 10% of the intensity of the room light around the outer top surface of the press at such wavelength. See Final Act. 3 (citing Onuma items 21 and 77). Therefore, the preponderance of the evidence supports the Examiner’s finding that the combination of Onuma, Mori, Dupertuis, and Goodin teaches or suggests each of the elements of claim 1. For the reasons stated above and in the Answer, including the Response to Argument, we affirm the Examiner’s decision to reject claim 1 under 35 U.S.C. § 103(a) as unpatentable over the combination of Onuma, Mori, Dupertuis, and Goodin. Claim 9 Regarding claim 9, which depends from claim 1 and recites “a light-tight cassette containing at least one lithographic plate,” the Examiner finds that Blake evidences it was known to handle plates in a light-tight environment in order to prevent unintentional exposure of the photosensitive plate, and specifically teaches putting printing plates in a light-tight cassette. Final Act. 8 (citing Blake 2:18–20, 3:67–4:1). The Examiner determines that it would have been obvious to one of ordinary skill in the art to “modify the lithographic plate of Onuma to be housed in a light-tight cassette in order to prevent unintentional exposure of the photosensitive plate as suggested by Blake.” Id. (citing Blake 2:18–20). According to Appellant, Blake discloses a plate handler which contains a supply of light-tight plate cassettes “for handling, imaging and processing of a plate before the plate is put on press for printing.” App. Br. 12 (citing Blake Fig. 1, 3:51–56). Appellant argues that “Blake et al only teach a placesetter including a plate handler as well as the handling of the plate on such a placesetter (including a Appeal 2015-006316 Application 12/176,377 8 plate handler), but do not teach a printing press.” Id. Appellant also argues that none of the cited references including Blake discloses “a press having covers with certain areas which are non-transparent to any white light and other areas which are only transparent to a yellow or red light.” Id. Appellant reiterates the same argument in the Reply Brief and adds “for a plate which is safe under white light, it is generally not beneficial to use a light-tight cassette as it will make the design and manufacture unnecessarily more complicated and more expensive.” Reply Br. 3– 4. We are not persuaded by Appellant’s arguments for essentially the same reasons discussed above in connection with independent claim 1. Appellant’s arguments also are unpersuasive because the Examiner’s finding that “Blake teaches a light-tight cassette . . . in order to prevent unintentional exposure of the photosensitive plate” is supported by Blake’s disclosure. Final Act. 8 (citing Blake 2:18–20, 3:67–4:1). Appellant’s argument that Blake does not disclose covers is unpersuasive because the Examiner cites Onuma for teaching “a compartment shielded with covers” (Final Act. 2). Moreover, Blake states “[t]he functions [handling unexposed plates] are optionally performed within a covered light-tight environment to prevent unintentional exposure of the light sensitive plate surface” and that “[c]overs and doors (not shown) are provided to enclose the entire handler frame to maintain the cassette in a light tight environment.” Blake 2:18–20, 11:48–50. Additionally, Appellant’s belated argument in the Reply Brief that a light-tight cassette would introduce complexity and expense if not needed, does not negate the Examiner’s finding that “preventing unintentional exposure of a photosensitive plate would be beneficial.” Ans. 3; cf. Reply Br. 3. Therefore, the preponderance of the evidence on this record supports the Examiner’s reason for combining Blake’s teaching about preventing unintentional exposure of a Appeal 2015-006316 Application 12/176,377 9 photosensitive plate to further modify the lithographic plate of Onuma to be housed in a light-tight cassette. Claim 10 Regarding claim 10, which depends from claim 1 and recites “the lithographic plate is in the form of continuous web,” the Examiner finds Fuhrmann evidences that at the time of the invention, it was known in the art to use a cartridge to easily change out used printing web. Final Act. 9 (citing Fuhrmann Fig. 1, item 130, 2:23–28). The Examiner concludes that it would have been obvious to one of ordinary skill in the art “to further modify the plate of Onuma to be inside a cartridge in order to easily change out used printing web as suggested by Fuhrmann.” Id. (citing Fuhrmann 2:23–28). The Examiner further concludes that “it would have been obvious to one of ordinary skill in the art at the time of invention to further modify the lithographic plate of Onuma to be housed in a light- tight cassette in order to prevent unintentional exposure of the photosensitive plate as suggested by Blake (column 2, lines 18–20).” Id. at 9. Appellant asserts the rejection of claim 10 is improper for the same reasons discussed above with respect to independent claim 1. App. Br. 14–15. In addition, Appellant asserts that Fuhrmann also “do[es] not teach press covers with certain areas which are non-transparent to any white light and other areas which are only transparent to a yellow or red light.” Id. at 14. Appellant contends that there is no apparent need to handle the plate of Onuma, Mori, or Fuhrmann in a light-tight cassette of Blake or under the yellow room light of Goodin, and that even under the conditions of yellow room light of Goodin, there is no need for a light-tight cassette. Id. at 15. In the Reply Brief, Appellant contends that: neither any individual reference nor the combination of all the references teaches or suggests a press cover with certain areas which are non-transparent to any white light and other areas which are only Appeal 2015-006316 Application 12/176,377 10 transparent to a yellow or red light, which press cover is a key element of the invention and is a limitation of the claims. Reply Br. 5. We are not persuaded by Appellant’s arguments for the reasons discussed above in connection with independent claim 1. Appellant’s arguments also are unpersuasive because the record does not show that it would be beyond the skill of one of ordinary skill in the art to select a material for the covers of the plate mounted on the plate cylinder that is light safe for the particular photosensitive plate of the press. See KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 421 (2007) (“A person of ordinary skill is also a person of ordinary creativity, not an automaton.”). Claim 11 Regarding claim 11, which depends from claim 10, the Examiner finds: Williams teaches plate cylinder is mounted with 2 sets of plates, the first plate is mounted on the plate cylinder surface from about 0° to about 180° of the rotating direction of the cylinder with [the corresponding fresh and used plate rolls installed within the cylinder], and the second plate is mounted on the same plate cylinder surface from about 180° to about 360° (0°) of the rotating direction for multicolor printing as required by claim 11. Final Act. 10 (citing Williams Fig. 1, 4:14–16, 4:34–38). The Examiner concludes that it would have been obvious to one of ordinary skill in the art “to further modify the invention of Onuma to print multicolored images as suggested by Williams.” Id. (citing Williams Fig. 1, 4:14–16, 4:34–38). Appellant asserts the rejection of claim 10 is improper for the same reasons discussed above with respect to independent claim 1. App. Br. 16–17. Appellant does not dispute the Examiner’s findings with respect to Williams, but asserts that Williams also “does not teach any light-tight cartridge or cover for the plate, so the Appeal 2015-006316 Application 12/176,377 11 plate used on the press of Williams is not sensitive to white room light.” Id. at 16. Appellant contends that there is no apparent need to handle the plate of Onuma, Mori, Fuhrmann, or Williams in a light-tight cassette of Blake or under the yellow room light of Goodin, and that even under the conditions of yellow room light of Goodin, there is no need for a light-tight cassette. Id. at 15. In the Reply Brief, Appellant contends that: neither any individual reference nor the combination of all the references teaches or suggests a press cover with certain areas which are non-transparent to any white light and other areas which are only transparent to a yellow or red light, which press cover is a key element of the invention and is a limitation of the claims. Reply Br. 5. We are not persuaded by Appellant’s arguments for the reasons discussed above in connection with independent claim 1 and dependent claim 10. As explained above, the Examiner provides a persuasive reason for combining each reference to modify Onuma’s printing press based on the teachings of the references themselves. Each of Onuma, Mori, and Goodin exposes the plate in a lithographic press to laser irradiation for forming an image, Dupertuis teaches a removable window for viewing a cylinder under room light (Final Act. 3; Dupertuis ¶ 22, item 72), Goodin teaches handling undeveloped photosensitive printing plates in yellow light rooms or conditions to prevent exposure to incidental white light or sunlight (Final Act. 4; Goodin ¶ 8), Blake teaches a light- tight cassette in order to prevent unintentional exposure of the photosensitive plate (Final Act. 9; Blake 3:67–4:1), and Fuhrmann teaches a cartridge for easily changing out used printing web (Final Act. 9; Fuhrmann 2:23–28). Additionally, Appellant does not dispute the Examiner’s findings with respect to Williams or that Onuma teaches a plate: Appeal 2015-006316 Application 12/176,377 12 within a compartment shielded by covers and other press parts so that, when the covers are fully closed and when there is no light source turned on within said compartment, the intensity of the light at each wavelength below 450 nm around the plate cylinder is less than 10% of the intensity of the room light around the outer top surface of the press at such wavelength. See Final Act. 3 (citing Onuma items 21 and 77); id. at 10 (citing Williams Fig. 1, 4:14–16, 4:34–38). Therefore, the preponderance of the evidence supports the Examiner’s combination of Onuma, Mori, Dupertuis, Goodin, Fuhrmann, Blake, and Williams as well as the Examiner’s finding that the combination of Onuma, Mori, Dupertuis, Goodin, Fuhrmann, Blake, and Williams teaches or suggests each of the elements of claim 11. For the reasons stated above and in the Answer, including the Response to Argument, we affirm the Examiner’s decision to reject claims 1–5 and 7–12. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(1). AFFIRMED Copy with citationCopy as parenthetical citation
