M. WOOD, LEE L. STEPINA, and RICHARD H. MARSCHALL, Administrative Patent Judges. MARSCHALL, Administrative Patent Judge. DECISION ON APPEAL Appellant1 seeks our review under 35 U.S.C. § 134(a) of the Examiner's decision rejecting claims 1-5, 12, 13, 15, and 17-22.2 We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. 1 Appellant is the Applicant, Mitsubishi Aircraft Corporation, which the Appeal Brief identifies as the real party in interest. Appeal Br. 2. 2 Claims 6-11 and 14 are withdrawn, and claim 16 is cancelled. Appeal Br. 14--17 (Claims App.). Appeal2018-002259 Application 14/465,007 THE CLAIMED SUBJECT MATTER The claimed subject matter relates to "an aircraft window having an electromagnetic shielding function, and a closing member for an opening portion having an electromagnetic shielding function." Spec. 1. Claims 1 and 12 are independent. Claim 1, reproduced below, is illustrative of the claimed subject matter. 1. An aircraft window provided in an airframe of an aircraft, comprising: a window body including a window panel having light transmissibility, and an electromagnetic shield layer laminated on the window panel; a window frame that is made of a conductive material, and that surrounds the window body; an interposition member that is formed by using a rubber- based material combined with a conductive material that provides the interposition member with conductivity, the interposition member being at least partially held between the window body and the window frame; and a conductive layer that is located between the window body and the interposition member, and that brings the electromagnetic shield layer and the interposition member into conduction with each other, wherein the window frame includes a holding section that holds the window body via the interposition member from an airframe outer side, at least a part of the conductive layer extends to a portion of the window body facing an extending part of the holding section, and the conductive layer has a surface resistivity of 0.5 Q/sq or lower. Appeal Br. 14 (Claims App.). 2 Appeal2018-002259 Application 14/465,007 THE REJECTIONS 3 Appellant seeks review of the following rejections on appeal: 1. Claims 1-5, 12, 13, 15, 18, 19, 21, and 22 under 35 U.S.C. § 103 as unpatentable over Bain, 4 Kirchoff, 5 Chaussade, 6 and DiLeo. 7 2. Claims 17 and 20 under 35 U.S.C. § 103 as unpatentable over Bain, Kirchoff, Chaussade, DiLeo, and Applicant Admitted Prior Art, or, in the alternative, under 35 U.S.C. § 103 as unpatentable over Bain, Kirchoff, Chaussade, DiLeo, and Kang. 8 3. Claims 1-5, 12, 13, 15, 18, 19, 21, and 22 under the doctrine of nonstatutory double patenting over claims 1, 16, and 20 of U.S. Patent No. 9,415,854 ("the '854 patent"), Bain, and DiLeo. ANALYSIS Obviousness The Examiner found that Bain discloses an aircraft window in an airframe that includes many of the claimed features of the window, including a window frame having a "holding section that holds the window body via the interposition member." Non-Final Act. 7. As to Kirchoff, the Examiner found that it discloses film or other shielding material 7 6 that reduces or attenuates electromagnetic radiation through the window, and a 3 In the Answer, the Examiner withdrew certain rejections under 35 U.S.C. § 112, and we do not consider those rejections in this appeal. Ans. 4--5. 4 U.S. Patent No. 4,793,108, issued December 27, 1988 ("Bain"). 5 U.S. Patent Pub. No. 2008/0308677 Al, published December 18, 2008 ("Kirchoff'). 6 U.S. Patent Pub. No. 2003/0087048 Al, published May 8, 2003 ("Chaussade"). 7 U.S. Patent No. 5,968,600, issued Oct. 19, 1999 ("DiLeo"). 8 WO 03/071846 Al, published August 28, 2003 ("Kang"). 3 Appeal2018-002259 Application 14/465,007 gasket with conductive material added to attenuate electromagnetic radiation. Id. at 7-8. As to Chaussade, the Examiner found that it discloses an "aircraft window providing electromagnetic protection" that includes electrically conductive layer 5 and conductive seal 3. Id. at 9. The Examiner also found that Chaussade discloses various methods of providing a "conductivity boost" to the seal, including use of a conductive film in the form of a silver lacquer and/or a metal foil or mesh tape against the periphery of the window and the internal part of the seal in contact with electrically conductive layer 5. Id. at 9-10. The Examiner relied on DiLeo as disclosing an EMI shielding coating including a silver-based paint having a surface resistivity of less than 0.5 ohms/sq as claimed. Id. at 10. The Examiner determined that it would have been obvious to modify Bain's aircraft window with the additional references to enhance conductivity between the electromagnetic film and the interposition member in a cost effective manner. See id. at 9, 11. Appellant makes several arguments against the obviousness rejections, and focuses the arguments on the language of claim 1. See Appeal Br. 6-11. First, Appellant argues that Chaussade is silent regarding bringing its electromagnetic shield 5 and seal into conduction with each other. Id. at 8. Second, Appellant argues that Chaussade fails to disclose extending its foils 6 to a portion of the window body facing an extending part of a window frame. Id. at 8-9. Third, Appellant argues that the rejection lacks sufficient reasoning to apply DiLeo's teaching of a resistivity of less than 0.5 ohms/sq for certain embodiments, when other embodiments show higher resistivity falling outside the scope of the claim. Id. at 10. 4 Appeal2018-002259 Application 14/465,007 The Examiner responds by noting that Chaussade discloses boosting "the conductivity between the conductive seal (interposition layer) and electromagnetic shield layer," which means that the two materials must be in conduction with one another. Ans. 10. As to the limitation requiring extension of the conductive layer "to a portion of the window body facing an extending part of the holding section," the Examiner found that Chaussade discloses applying the conductive layer along the edges and sides of the seal and that one of "ordinary skill in the art would recognize that providing the conductive layer over a greater surface area of the seal would further boost the conductivity of the seal." Id. at 13. This is so, according to the Examiner's findings, because "the conductive layer is more conductive than the seal-and the part of the seal along the extending part of the window holding section (as taught by primary reference Bain) is a large area that is also in contact with the conductive extending part and therefore is a large area through which electromagnetic energy from the electromagnetic shield would be conducted." Id. The Examiner determined that one would be motivated to extend at least a part of the conductive layer on the seal along the window facing Bain's extending portion "to increase the ability of the conductive layer to boost the seal conductivity by providing that conductive layer along more of the seal's surface area ... thereby improving the electromagnetic protection provided." Id. at 13-14. Finally, as to DiLeo's disclosure of resistivity, the Examiner notes that for every preferred embodiment, and the most preferred embodiment, DiLeo discloses resistivity values that fall within the claimed range, and the obviousness determination was based on the explicit preferred resistivity values noted in DiLeo rather than hindsight. Id. at 15-16. 5 Appeal2018-002259 Application 14/465,007 Appellant's arguments do not apprise us of error in the Examiner's rejection of claim 1. First, the argument that Chaussade fails to show its electromagnetic shield 5 and conductive seal 4 in conduction with one another fails to address or undermine the Examiner's finding that they must be in conduction with one another for the conductive layer (film or mesh or paint) to increase or "boost" the conduction between the two. See Ans. 1 O; Reply Br. 2. This finding is directly supported by Chaussade itself. See Chaussade ,r,r 28, 29, Figs. 2 and 3. Second, the Examiner adequately supported the finding that one would be motivated to extend the conductive layer "to a portion of the window body facing an extending part of the holding section." See Ans. 13- 14. In particular, the Examiner's finding that one of ordinary skill in the art would recognize that providing the conductive area over a larger area of the seal would boost conductivity, and that extending the layer over at least a portion of Bain's window body facing its extending part of the holding section would also increase conductivity and performance, is based on a rational underpinning. See id. ( citing Chaussade, Fig. 3). Appellant argues that the Examiner failed to cite specific references showing that providing the conductive layer over a larger surface area would boost conductivity, but the Examiner need not find additional references given that the Examiner's reasoning is supported by a straightforward and rational underpinning, and given that Appellant has not shown error in that reasoning. See Reply Br. 2. Appellant also argues that even if one were to add Chaussade' s foil 6 to Bain's seal 20, one would add it to the interior portion of seal 20 rather than the area facing a holding section of window frame 22. Id. at 3. This argument lacks any reasoned explanation or support in the record, and would 6 Appeal2018-002259 Application 14/465,007 seem to inexplicably limit the extension of the conductive layer to only a portion of seal 20, even though further extension of the conductive layer as claimed provides additional advantages. Third, the Examiner adequately supported the finding that DiLeo discloses an electromagnetic interference coating with surface resistivity within the claimed range, and that one of ordinary skill in the art would have been motivated to apply such a coating to the proposed combination. See Final Act. 10-11; Ans. 14--16. Contrary to Appellant's argument, DiLeo itself provides a reason to pick from embodiments that result in the claimed resistivity because all seven examples in DiLeo disclose resistivity in the claimed amount, and DiLeo describes these levels as "more preferred" or "most preferred" compared to results that fall outside the claimed range. See id.; DiLeo 9:50-57. Appellant contends that one of ordinary skill in the art may prefer to apply DiLeo 's coating to the electromagnetic shield layer rather than the conductive layer as claimed, but as the Examiner correctly notes, identifying another potential advantageous use of DiLeo' s coating does not suggest the coating would not have been obvious to apply elsewhere, such as the conductive coating. See Ans. 17; Reply Br. 5. Appellant also contends that the Examiner improperly proposes modifying Chaussade' s metal foil with metal paste/paint, but the Examiner makes no such finding. See Reply Br. 5; Ans. 8, 10, 11 (referring to paste/paint as an alternative to foil to boost conductivity); Final Act. 10 (same). We are not apprised of error in the Examiner's findings related to DiLeo. Based on the foregoing, we sustain the rejection of claim 1 as unpatentable as obvious. Appellant does not raise any additional arguments regarding the remaining claims under this rejection, except to repeat reliance 7 Appeal2018-002259 Application 14/465,007 on the arguments made with respect to claim 1. See Appeal Br. 11-12. Accordingly, we sustain the rejection of claims 2-5, 12, 13, 15, and 17-22 for the same reasons discussed above. Double Patenting The Examiner based the double patenting rejection on a combination of the '854 patent with Bain and DiLeo. See Final Act. 19-22. In the Appeal Brief, Appellant largely relied on the same arguments with respect to claim 1 discussed above when addressing the double patenting rejection. See Appeal Br. 12. Appellant also argues, in a single sentence, that claims 1, 16, and 20 of the '854 patent require "an electrical path to be formed through" various structures, which is not rendered obvious by the claims of the present application. Id. In response, the Examiner found that claim 1 of the present application effectively describes the "electrical path" noted in the claims of the '854 patent. Ans. 20. In Reply, Appellant argues that the Examiner failed to properly account for the "fixing member" in the claims of the '854 patent, which is not recited in the claims of the present application. Reply Br. 6. Appellant's arguments do not apprise us of error in the Examiner's double patenting rejection. First, Appellant does not contest the Examiner's findings in the rejection in the Appeal Brief, beyond the arguments discussed above in the context of the obviousness rejection. See Appeal Br. 12. The Examiner found that claims 1-5, 12, 13, 15, 18, 19, 21, and 22 were obvious in light of claims 1, 16, and 20 of the '854 patent, Bain, and DiLeo. Non-Final Act. 19-22. Appellant's single-sentence argument in the Appeal Brief that goes beyond the previously raised nonobviousness arguments addresses whether the claims of the '854 patent are obvious in light of the 8 Appeal2018-002259 Application 14/465,007 present claims in the application. See Appeal Br. 12. Because the rejection was not based on whether the claims of the '854 patent were obvious in light of the present claims-the rejection was based on the converse-Appellant's additional arguments do not apprise us of error in the rejection. Because Appellant's only arguments addressing those findings rely on the arguments we found unconvincing above, we sustain the double patenting rejection. Appellant's argument relating to the alleged nonobviousness of the claims in the '854 patent appears to assume that the double patenting rejection must not only establish the obviousness of the present claims in light of the '854 patent claims and the other references, as the Examiner found, but must also establish the obviousness of the '854 patent claims in light of the present claims. This is known as a "two-way" double patenting test. See In re Janssen Biotech, Inc., 880 F.3d 1315, 1325 (Fed. Cir. 2018). That test is required in "unusual" and "narrow" circumstances, "where (1) a second-filed application issues prior to a first-filed application, and (2) 'the PTO is solely responsible for the delay."' See id.; see also In re Fall aux, 564 F.3d 1313, 1315-18; MPEP §804(II)(B)(2)(b) ("If the application under examination is the later-filed application, or both applications are filed on the same day, only a one-way determination of distinctness is needed in resolving the issue of double patenting, i.e., whether the invention claimed in the application would have been anticipated by, or an obvious variation of, the invention claimed in the patent."). Appellant made no effort to establish that the Examiner was required to apply a two-way test for double patenting, and therefore the argument regarding the alleged nonobviousness of the '854 patent claims lacks a proper foundation, and does not establish error in the 9 Appeal2018-002259 Application 14/465,007 Examiner's rejection. 9 The Examiner properly applied the one-way test for double patenting, and for the reasons discussed above Appellant has not established error in those findings. To the extent that the Examiner entertained Appellant's argument based on the two-way test, 10 we view that analysis as unnecessary to sustain the rejection, which does not rely on the two-way test. DECISION We affirm the decision of the Examiner to reject claims 1-5, 12, 13, 15, and 17-22. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a). See 37 C.F.R. § 1.136(a)(l )(iv). AFFIRMED 9 Based on our own review of the record, it appears unlikely that the two- way test could apply, given that the '854 patent was filed on July 3, 2014 (with a priority claim to an application filed July 27, 2012), before the filing date of the present application on August 21, 2014. 10 The Examiner found that the structures in the present claims disclosed the "electrical path" limitation in the claims of the '854 patent. See Ans. 21. Appellant maintains that the Examiner did not give proper weight to the "fixing member" in the '854 patent claims. See Reply Br. 6. The fixing member appears to be a clamp and/or clip that fixes the window in place, as disclosed in both the '854 patent and the current specification. See '854 patent, Fig. 1 (item 28), 6:63-7:2; Spec. Fig. 1 (item 27). Although we need not reach the issue because Appellant has not established that the two-way test applies, it appears that Bain discloses such a structure such that the combination of the present claims with Bain would render the '854 patent claims obvious. See Bain, Fig. 1 (item 26), 2:26-29 ("retainer clip assembly 26"). 10 Copy with citationCopy as parenthetical citation
