REFERENCES AND REJECTIONS The Examiner relies upon the following references: Name3 Reference Issued/Publ’d Filed Sonoda US 5,768,217 June 16, 1998 May 12, 1997 Hill US 2008/0165065 A1 July 10, 2008 Jan. 4, 2007 Zhang US 2009/0040115 A1 Feb. 12, 2009 Aug. 7, 2007 3 All reference citations are to the first named inventor only. Appeal 2020-006645 Application 15/424,605 4 The Examiner rejects claims 1–7 and 15–20 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Zhang and Hill. Final Act. 2–9. The Examiner also rejects claims 8–10, 13, and 14 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Zhang and Sonoda. Id. at 9–13. Further, the Examiner rejects claims 11 and 12 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Zhang, Sonoda, and Hill. Id. at 13– 14. We review the appealed rejections for error based upon the issues identified by Appellant, and in light of the contentions and evidence produced thereon. Ex parte Frye, 94 USPQ2d 1072, 1075 (BPAI 2010) (precedential). The Examiner and Appellant focus their findings and contentions on claims 1, 7, 8, and 15; so do we. See Appeal Br. 3–9; Ans. 3–9; Reply Br. 2–10. Arguments not made are waived. See 37 C.F.R. § 41.37(c)(1)(iv). Unless otherwise indicated, we adopt the Examiner’s findings in the Final Office Action and the Answer as our own and add any additional findings of fact for emphasis. We address the rejections below. ANALYSIS A. Obviousness Over Zhang and Hill As noted above, the Examiner rejects claims 1–7 and 15–20 as obvious over the combined teachings of Zhang and Hill. Final Act. 2–9. Appellant contests the rejection of claims 1, 7, and 15 separately. Appeal Br. 6–9, 11–13. For the reasons given below, we are not persuaded the Examiner errs, and we sustain this rejection. Appeal 2020-006645 Application 15/424,605 5 1. Independent Claim 1 With respect to claim 1, the Examiner finds that Zhang teaches or suggests the majority of the recited limitations. Final Act. 2–3. In particular, the Examiner finds Zhang discloses an electronic device, such as device 10 depicted in Zhang’s Figure 1, having opposing front and rear surfaces. Id. at 2. The Examiner also finds Zhang’s device 10 has housing 12 including sidewalls 12–1 and dielectric portions 12-2A and 12-2B that form at least a portion of a rear surface of the electronic device. Id. (citing Zhang, Fig. 4A). Further, the Examiner finds Zhang discloses antenna 54 has antenna ground plane 54-2 and antenna resonating element 54-1B formed on dielectric member 12-2A and/or 12-2B. Id. (citing Zhang ¶ 91, Fig. 9). In addition, Zhang teaches or suggests the dielectric member may “form the rear surface of the dielectric device.” Zhang ¶ 39 (“In some situations, housing 12 or portions of housing 12 may be formed from a dielectric or other low-conductivity material, so that the operation of conductive antenna elements that are located in proximity to housing 12 is not disrupted.”); see Final Act. 3. The Examiner finds “Zhang does not disclose the new added limitation ‘wherein the antenna resonating element is attached to the dielectric member with an adhesive.’” Final Act. 3. Nevertheless, the Examiner finds that Hill discloses, “[r]esonating element 54-1 may be formed by any suitable antenna fabrication technique such as . . . patterning metal such as copper that makes up part of a flex circuit substrate that is attached to support 102 by adhesive, screws, or other suitable fastening Appeal 2020-006645 Application 15/424,605 6 mechanisms, etc.” Id. at 3 (quoting Hill ¶ 724 (emphasis added)). Hill further explains, “Support structure 102 may be formed from plastic (e.g., ABS plastic) or other suitable dielectric.” Hill ¶ 71 (emphasis added). Thus, the Examiner finds that a person of ordinary skill in the relevant art would have had reason to combine the teachings of Zhang and Hill to achieve the devices, as recited in claim 1. Final Act. 4. We further note that Zhang discloses antenna resonating element 54- 1B may be attached to dielectric antenna resonating element support structure 90 by inserting support structure post 110 in antenna resonating element post hole 116 and resonating antenna element end 76 in support structure hole 114. Zhang ¶ 101, Fig. 18; see id. ¶ 91 (“Antenna resonating element 54-1B may be a free-standing structure, a trace that is patterned on the surface of a substrate such as a flex circuit, or may be attached to other suitable mounting structures.” (emphasis added)). Thus, we agree that an ordinarily skilled artisan would have had reason to form the claimed invention so that with one suitable arrangement, the resonating element structures of [Hill’s] FIG. 12 are formed as part of a patterned flex circuit that is attached to antenna cap support structure 102 (e.g., by adhesive)[,] (Hill [¶ 72]]) therefore, securing the antenna to the dielectric member and prevent movement. Final Act 4. Appellant contends the Examiner errs in rejecting claim 1 for four reasons. Appeal Br. 6–8; Reply Br. 2–7. After considering those reasons, we are not persuaded the Examiner errs. 4 Although the Examiner cites to “para. 0121” of Hill, we understand the correct citation to be to Hill ¶ 72. See Appeal Br. 7; Ans. 4. Appeal 2020-006645 Application 15/424,605 7 First, Appellant contends “neither Zhang nor Hill shows or suggests an antenna resonating element attached to a dielectric member that forms a rear surface of an electronic device.” Id. at 6–7. In particular, Appellant contends Zhang’s Figures 8 and 105 show antenna resonating element 54-1B is attached to mounting structure 66 and “[m]ounting structure 66 does not form the rear surface of Zhang’s device, as it is covered by dielectric portion 12-2.” Id. at 7. Further, because Zhang discloses “the tail of the first antenna’s resonating element may be mounted in a location in the interior of device 10 so that the tail is not immediately adjacent to the surface of housing portion 12- 2B” (see [Zhang ¶ 65]). Zhang’s antenna resonating element 54- 1B is therefore not equivalent to the antenna resonating element mounted on a dielectric member that forms the rear face of an electronic device, as recited in claim 1. Appeal Br. 7. We disagree. Claim 1 recites, “a housing comprising conductive sidewalls and a dielectric member that forms the rear surface of the electronic device.” Appeal Br. 15 (Claims App.) (emphasis added). The Specification explains, “the rear surface of device 10 (i.e., the surface opposing the front side that contains display 14) may be formed from a planar dielectric structure (e.g., a glass plate, a ceramic plate, etc.). Antennas may be formed under this type of rear plate or under other dielectric device structures.” Spec., 11:12–25 (emphasis added); see id. at Fig. 5. Thus, we understand Zhang’s dielectric 5 Although the Examiner relies on Zhang’s Figures 1, 3B, 4A, 5A, 9, and 16, but not Figure 8 or 10, in the Final Office Action (Final Act. 2; Ans. 4), Zhang’s Figure 8 also supports the Examiner’s findings regarding Zhang’s teachings (Ans. 4 (citing Zhang ¶ 86)). Appeal 2020-006645 Application 15/424,605 8 portions 12-2A and 12-2B define surfaces opposing the front side of the device that contains a display. Zhang’s Figure 3B, including our annotations, is reproduced below. Figure 3B is a cross-sectional side view of an illustrative handheld electronic device with an antenna structure in accordance with an embodiment disclosed in Zhang. Zhang ¶ 18. Referring to Zhang’s Figure 1, conductive portion 12-1, as depicted in Figure 3B, surrounds the edge of display 16. See id. ¶¶ 15, 41, 42. The Examiner finds “Zhang clearly discloses in Figure 3B an antenna resonating element (54-1B) formed to a dielectric member (dielectric portions 12-2a and 12-2B) that forms the rear surface of an electronic device (See Figure 5 wherein dielectric member 12-2A and 12-2B forms the rear surface of device 10).” Ans. 4. Moreover, this finding is consistent with Zhang’s preference for locating the antenna’s tail away from the housing’s surface. See id. (citing Zhang ¶ 86, Fig. 8); see also Zhang ¶ 65 (“The second end of the first antenna’s resonating element, which is sometimes referred to as its tail, may be positioned in a location that is relatively insensitive to proximity effects.” (emphasis added)). Thus, we agree with Appeal 2020-006645 Application 15/424,605 9 the Examiner that Zhang’s dielectric members 12-2A and 12-2B teach or suggest “a dielectric member that forms the rear surface of the electronic device,” as recited in claim 1. Second, Appellant contends Hill does not teach or suggest attaching antenna resonating elements to a dielectric member by adhesive. Appeal Br. 7–8; Reply Br. 4. Referring to Figure 3B, reproduced above, Appellant contends that Zhang’s antenna resonating element 54-1B is formed between dielectric portion 12-2B and conductive housing portion 12-1. Reply Br. 2– 3 (citing Zhang ¶ 64). Appellant concludes that Figure 3B “merely shows that antenna resonating element 54-1B is formed within housing 12 and fails to show or suggest that antenna resonating element 54-1B is attached to dielectric portion 12-2B, as recited in claim 1.” Id. at 3 (emphasis added). Appellant contends that “[a]lthough Hill does disclose that adhesive is used in attaching the resonating element to the support structure (see [Hill ¶ 72]), Hill fails to show or suggest that support structure 102 forms a rear face of an electronic device.” Appeal Br. 7–8. Appellant, however, misunderstands the Examiner’s reliance on Hill. Hill discloses that antenna resonating element 54-1 may be attached to dielectric support structure 102 by adhesive, screws, or other suitable fastening mechanisms. Hill ¶ 72 (emphasis added). As the Examiner explains: The Examiner recognized that the Zhang reference discloses antennas (54-1B) formed in dielectrics and not attached. Therefore, the Examiner relied on the Hill reference to specifically address the limitation “wherein the antenna resonating element is attached to the dielectric member with an adhesive”. (See [Final Act. 3–4]) Appeal 2020-006645 Application 15/424,605 10 Based on Hill’s teachings on the use of adhesives to attach antenna elements on the dielectric (support structure 102 in Hill’s Figure 12 and paragraph 72) one of ordinary skill would have used the adhesives according to Hill to attach antenna elements to the dielectric structures 12-2B of Zhang which form part of the rear surface of the electronic device (as shown in Zhang Figure 5). Ans. 4. Thus, the Examiner relies on Hill to teach or suggest that a person of ordinary skill in the relevant art would have known to attach with adhesive an antenna resonating element to a dielectric member in a handheld electronic device. Hill ¶ 72, Fig. 12; see Zhang ¶¶ 91, 101, Fig. 18 (discussed above); see also Zhang ¶ 39 (housing 12 or portions thereof may be formed from dielectric materials). Thus, we agree with the Examiner that Hill teaches the missing limitations of Zhang. Third, Appellant contends Zhang teaches away from attaching antenna resonating element 54-1B to dielectric portion 12-2A or 12-2B. Reply Br. 5–6. In particular, Appellant contends, Zhang teaches that it is “desirable to minimize proximity effects” ([Zhang ¶ 52]). Although the antenna resonating element tail portion may be the most susceptible to increased proximity effects, any decrease in the distance between resonating element 54-1B and dielectric portion 12-2B would increase the proximity effects when a user touches dielectric portion 12-2B. Zhang’s focus on minimizing proximity effects would lead one of ordinary skill away from attaching resonating element 54-lB to dielectric portion 12-2B. Id. (bolded italics added). The Examiner finds, however, that Zhang merely teaches a preference for having at least a portion of the antenna resonating element, the tail of the antenna resonating element, “mounted in a location in the interior of device 10 so that the tail is not immediately adjacent to the surface of housing Appeal 2020-006645 Application 15/424,605 11 portion 12-2B.” Ans. 4–5 (quoting Zhang ¶ 65). “A reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 53 (Fed. Cir. 1994). “The fact that the motivating benefit comes at the expense of another benefit, however, should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another. Instead, the benefits, both lost and gained, should be weighed against one another.” Winner Int'l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000); see DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1327 (Fed. Cir. 2009) (“A reference does not teach away . . . if it merely expresses a general preference for an alternative invention[.]”). As noted above, we are not persuaded that locating the tail of an antenna resonating element in the interior of the device and away from the user’s touch is inconsistent with the Examiner modifications to the teachings of the applied references. Thus, on this record, we are not persuaded that Zhang teaches away from the devices recited in claim 1. Fourth, Appellant contends the Examiner relies on improper hindsight to combine the teachings of Zhang and Hill to achieve the devices, as recited in claim 1. Appeal Br. 8; Reply Br. 6–7. In particular, Appellant contends, “[n]either Zhang nor Hill, alone or in combination, shows or suggests attaching an antenna member to a dielectric member that forms a rear surface of an electronic device. This positively claimed feature is only gleaned from applicant's disclosure.” Appeal Br. 8; Reply Br. 6. Appeal 2020-006645 Application 15/424,605 12 As the Examiner notes, any judgement on obviousness is in any sense necessarily a reconstruction based upon hindsight reasoning. But so long as it takes into account only knowledge which was within the level of ordinary skill at the time the invention was made, and does not include knowledge gleaned only from the Appellant’s disclosure, such a reconstruction is proper. Ans. 5 (citing In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971)). As discussed above, the Examiner relies on Zhang’s teachings regarding capping an antenna resonating element with a dielectric portion (e.g., Zhang ¶ 64) and Hill’s teachings regarding attaching an antenna resonating element to a dielectric support structure with adhesive (e.g., Hill ¶ 72) to find that a person of ordinary skill in the relevant art, aware of these teachings, would have had reason to attach an antenna resonating element with a dielectric portion with adhesive. Final Act. 4. In light of Zhang’s further teaching that an antenna resonating element may be attached to a dielectric support structure, we are not persuaded the Examiner’s combination of the teachings of Zhang and Hill relies on improper hindsight. See Zhang ¶¶ 91, 101, Fig. 18. We are not persuaded the Examiner errs in rejecting claim 1 as obvious over the combined teachings of Zhang and Hill, and we sustain that rejection. Further, Appellant does not challenge the obviousness rejection of dependent claims 2–6 separately from its challenge to their base claim, independent claim 1; and, therefore, we also sustain the rejection of those claims. Appeal 2020-006645 Application 15/424,605 13 2. Dependent Claim 7 Claim 7 depends directly from independent claim 1 and recites the electronic device “wherein the dielectric member comprises transparent dielectric material.” Appeal Br. 16 (Claims App.) (emphasis added). The Examiner finds Zhang discloses that housing 12, including dielectric portion 12-2A or 12-2B, may be made from glass, which a person of ordinary skill in the relevant art would have known may be transparent. Final Act. 6; Ans. 6. Appellant contends: Zhang’s cover portion 12-2B, which was suggested to be equivalent to the “dielectric member” of claim 7, is intended to “serve as caps that cover antennas that are mounted within housing 12” ([Zhang ¶ 64]). One of ordinary skill would not have made dielectric portion 12-2B “transparent,” as doing so would reveal the underlying antenna to a user and be unsightly. Appeal Br. 9. Appellant offers no evidence supporting this contention. Contentions of counsel, however, cannot take the place of factually supported objective evidence. See, e.g., In re Huang, 100 F.3d 135, 139-40 (Fed. Cir. 1996); In re De Blauwe, 736 F.2d 699, 705 (Fed. Cir. 1984). We are not persuaded that the Appellant’s unsupported contentions regarding unsightliness outweigh Zhang’s clear teachings regarding the use of glass in fabricating a dielectric housing or portions thereof. Zhang ¶ 39; see also Sonoda, 2:50–56 (disclosing application of a printed insulating ink layer to one surface of a transparent plate to render the plate opaque and “thereby improve the appearance of the timepiece”); cf. Spec., 2:26–3:8 (“A layer of opaque masking material such as a layer of patterned black ink may be provided on the underside of the transparent rectangular display member to block interior device components from view.”). Thus, we are not Appeal 2020-006645 Application 15/424,605 14 persuaded the Examiner errs in rejecting claim 7 as obvious over the combined teachings of Zhang and Hill, and we sustain that rejection. 3. Independent Claim 15 The Examiner again relies on substantially the same teachings of Zhang to teach or suggest the majority of the limitations of independent claim 15. Final Act. 6–7. Nevertheless, the Examiner finds: Since Zhang does not explicitly teach[] “antennas with conductive traces formed directly on the dielectric structures” the Examiner used Hill figures 1 and 13 and [Hill ¶ 33]6 to show antenna with conductive traces (in this case bezel 14 that can also be used as an antenna) can be formed directly on the dielectric housing 12 with proper motivation to combine the two references. Ans. 8; see Final Act. 7. The Examiner finds “Hill in figure 1 and 13 teaches an electronic device comprising dielectric structures (Housing 12, [Hill ¶ 33]) opposite the display cover (bezel 14) that form an entirety of a rear surface of the electronic device opposite the front surface 14.” Final Act. 7; see Zhang ¶ 41 (describing position of bezel 14 in device 10). Zhang discloses, “[t]he first antenna (depicted as antenna 54 in FIG. 3A) may be formed from an elongated resonating element such as strip of stamped conductor or a trace on a flex circuit.” Zhang ¶ 65 (emphasis added). Further, the Examiner finds a person of ordinary skill in the relevant art would have had reason to combine the teachings of Zhang and Hill to achieve the devices, as recited in claim 15. Final Act. 7. 6 Although the Examiner cites to “para. 0065” of Hill, we understand the correct citation to be to Hill ¶ 33. Appeal 2020-006645 Application 15/424,605 15 Appellant contends the Examiner errs in rejecting claim 15 for three reasons. Appeal Br. 11–13; Reply Br. 8–10. After considering those reasons, we are not persuaded the Examiner errs. First, similar to the contentions presented with respect to claim 1, Appellant contends Zhang does not teach or suggest “an antenna comprising an antenna ground, an antenna resonating element that includes conductive traces formed directly on the dielectric structures,” as recited in claim 15. Appeal Br. 12; see id. at 19 (Claims App.) (claim 15). In particular, Appellant contends Zhang’s Figures 8 and 107 show antenna resonating element 54-1B is attached to mounting structure 66 and “[m]ounting structure 66 does not form the rear surface of Zhang’s device, as it is covered by dielectric portion 12-2.” Id. at 11–12. Further, because Zhang discloses “the tail of the first antenna’s resonating element may be mounted in a location in the interior of device 10 so that the tail is not immediately adjacent to the surface of housing portion 12-2B” (see [Zhang ¶ 65]). Zhang’s antenna resonating element 54-1B is therefore not equivalent to the antenna resonating element mounted on a dielectric member that forms the rear face of an electronic device, as recited in claim 1. Id. at 12. For substantially the same reasons given above with respect to claim 1, Appellant’s contention is unpersuasive. We agree with the Examiner that Zhang discloses antenna resonating element 54-1 that includes conductive traces formed directly on dielectric substrate 90. Final Act. 6–7 (citing Zhang ¶¶ 71, 89, 91, Fig. 9). In particular, Zhang discloses: 7 See supra note 5. Appeal 2020-006645 Application 15/424,605 16 Antenna resonating element 54-1B may be formed from a strip of metal (as an example). Antenna resonating element 54- 1B may be a free-standing structure, a trace that is patterned on the surface of a substrate such as a flex circuit, or may be attached to other suitable mounting structures. With one illustrative arrangement, which is sometimes described herein as an example, antenna 54 is formed from a strip of metal that is mounted to a dielectric support structure such as support structure 90 (sometimes referred to as a chassis or carrier). Zhang ¶ 91 (emphases added). Thus, we agree with the Examiner’s finding that Zhang teaches or suggests the disputed limitation. Second, Appellant contends, “[e]ven if Zhang were modified based on the teachings of Hill, the combination would not have antenna resonating element conductive traces directly on a dielectric member that forms a rear face of a device.” Appeal Br. 12–13; Reply Br. 9–10. In particular, Appellant contends, “Hill merely discloses that conductive traces are used to form resonating element 54-1, which is attached to support structure 102, which in turn is an extension of ground plane 54-2.” Reply Br. 9 (citing Hill ¶ 69, Fig. 12); see Appeal Br. 12 (“Hill fails to show or suggest that support structure 102 forms a rear face of an electronic device.”). Nevertheless, the Examiner does not rely on Hill to teach or suggest that support structure 102 forms a rear face of an electronic device. Instead, the Examiner finds Zhang discloses the entire housing may be formed of a dielectric. Final Act. 7 (citing Zhang ¶ 39); see Ans. 8; see also Hill ¶ 33 (“In some situations, case 12 may be formed from a dielectric or other low- conductivity material, so that the operation of conductive antenna elements that are located in proximity to case 12 is not disrupted.”). The Examiner relies on Zhang to teach or suggest such a dielectric support structure may be a portion of the housing “opposite the display cover layer that form an Appeal 2020-006645 Application 15/424,605 17 entirety of a rear surface of the electronic device opposite the front surface.” Final Act. 6 (citing Zhang ¶ 42, Figs. 3B, 4A). The Examiner finds Hill discloses that an antenna resonating element including conductive traces may be formed directly on a dielectric support structure, such as support structure 102. Ans. 8; see Hill ¶ 71 (“Arms 98 and 100 [of an antenna resonating element] may be formed directly on support structure 102 or may be formed on a separate structure such as a flex circuit substrate that is attached to support structure 102 (as examples).” (emphasis added)), ¶ 72 (“Resonating element 54-1 may be formed by any suitable antenna fabrication technique such as metal stamping, cutting, etching, or milling of conductive tape or other flexible structures, etching metal that has been sputter-deposited on plastic or other suitable substrates . . . .” (emphasis added)). Thus, Hill teaches that an antenna resonating element including conductive traces may be formed on suitable substrates, and we agree the combined teachings of Zhang and Hill teach or suggest the disputed limitation. Third, Appellant again contends the Examiner relies on improper hindsight to combine the teachings of Zhang and Hill to achieve the devices, as recited in claim 15. Appeal Br. 13; Reply Br. 10. Given the discussion above of the teachings of Zhang and Hill, we are persuaded the Examiner relies on knowledge that was within the level of ordinary skill at the time of the application, and we are not persuaded the Examiner relies on knowledge gleaned only from the Appellant’s disclosure.8 Final Act. 7; Ans. 8–9. Therefore, we are not persuaded the Examiner relied on improper hindsight 8 See supra Section A.1. (discussing alleged improper hindsight). Appeal 2020-006645 Application 15/424,605 18 to find the combined teachings of Zhang and Hill render obvious the devices, as recited in claim 15. We are not persuaded the Examiner errs in rejecting claim 15 as obvious over the combined teachings of Zhang and Hill, and we sustain that rejection. Further, Appellant does not challenge the obviousness rejection of dependent claims 16–20 separately from its challenge to their base claim, independent claim 15; and, therefore, we also sustain the rejection of those claims. B. Obviousness over Zhang and Sonoda As noted above, the Examiner rejects claims 8–10, 13, and 14 as obvious over the combined teachings of Zhang and Sonoda. Final Act. 9– 13. Appellant only contests the rejection of independent claim 8. Appeal Br. 9–11. For the reasons given below, we are not persuaded the Examiner errs, and we sustain this rejection. The Examiner yet again relies on substantially the same teachings of Zhang to teach or suggest the majority of the limitations of independent claim 8. Final Act. 9–10. In particular, claim 8 recites “conductive traces mounted on the dielectric member that receive wireless signals through the dielectric member.” Appeal Br. 17 (Claims App.). The Examiner finds, “Zhang in figure 9 discloses: conductive traces mounted on the dielectric member 90 ([Zhang ¶¶ 65, 71]) that receive wireless signals through the dielectric member (90 and 12-2A and 12-2B); and first and second feed terminals (86/88) coupled to the conductive traces ([Zhang ¶¶ 71, 89, 91]).” Final Act. 9–10. For purposes of clarity, however, the Examiner also finds: Sonoda in figures 1 and 2 teaches conductive traces (antenna 20 formed from a combination of conductive ink layer 23 is Appeal 2020-006645 Application 15/424,605 19 provided so that the plated metal layer 23) mounted on the dielectric member (transparent plate 5) that receive wireless signals through the dielectric member 5; and first and second feed terminals (terminal 21) coupled to the conductive traces 20. Id. at 10. Nevertheless, the Examiner acknowledges “Zhang does not disclose the [Markush] limitation ‘wherein the dielectric member is formed from a material selected from the group consisting of: glass and ceramic[.]’” Id. at 11. Zhang discloses, however, “[a]ntenna resonating element dielectric support structure 90 may be formed from plastic or any other suitable dielectric.” Zhang ¶ 92; see id. ¶ 39 (“Housing 12, which is sometimes referred to as a case, may be formed of any suitable materials including, plastic, glass, ceramics, metal, or other suitable materials, or a combination of these materials.” (emphases added)); see also Sonoda, 3:21–24 (“Fitted in the upper casing 3 is a transparent plate 5 made of an acrylic or polycarbonate resin or glass” (emphasis added)). Further, the Examiner finds a person of ordinary skill in the relevant art would have had reason to combine the teachings of Zhang and Sonoda to achieve the devices, as recited in claim 8. Final Act. 10–11. Appellant contends the Examiner errs in rejecting claim 8 for three reasons. Appeal Br. 9–11; Reply Br. 7–8. After considering those reasons, we are not persuaded the Examiner errs. First, similar to the contentions presented with respect to claim 1, Appellant contends Zhang does not teach or suggest, “conductive traces mounted on the dielectric member that receive wireless signals through the dielectric member.” Appeal Br. 10; see Reply Br. 7–8. In particular, Appellant again contends, “Zhang merely discloses mounting an antenna Appeal 2020-006645 Application 15/424,605 20 resonating element (54-1B) on a circuit board (66) and covering the element and circuit board with a dielectric member (12-2B).” Reply Br. 7. We disagree. For the reasons discussed above with respect to claim 1, we agree Zhang teaches or suggests mounting an antenna resonating element, which may include conductive traces, on a dielectric support structure and that such a structure may include a dielectric portion, such as dielectric portion 12-2A or 12-2B. See Zhang ¶¶ 39, 64, 71, 89, 91, 101, Figs. 3B, 4A, 5A, 9, 18. Further, Sonoda’s Figure 2, including our annotations, is reproduced below. Figure 2 depicts a fragmentary, enlarged cross-sectional view of an electronic wristwatch according to Sonoda. Sonoda, 2:62–63. As noted above, transparent plate 5 may be made of a dielectric material, such as glass, and antenna 20 may receive signals through transparent plate 5. Id. at 3:21–24, 3:67–4:2. Thus, we agree that Zhang, alone or in combination with Sonoda, teaches or suggests, “conductive traces mounted on the dielectric member that receive wireless signals through the dielectric member,” as recited in claim 8. See Final Act. 9–10. Appeal 2020-006645 Application 15/424,605 21 Second, Appellant contends, Zhang teaches away from having the antenna resonating element “immediately adjacent to the surface of housing portion 12-2B” it would increase proximity effects when a user is holding the device ([Zhang ¶ 65]). Zhang therefore cannot be modified to have a dielectric member form a rear face of the device and “conductive traces mounted on the dielectric member," as in claim 8. Doing so would increase interference with the conductive traces, against which Zhang teaches. Appeal Br. 10; see Reply Br. 8. For substantially the same reasons discussed above with respect to claim 1, we are not persuaded that Zhang teaches away from the mounting of an antenna on a dielectric portion, such as dielectric portion 12-2A or 12-2B. Ans. 7–8. Third, Appellant contends, “Sonoda fails to show an antenna mounted to a dielectric member [that] forms a rear surface of an electronic device. Instead, Sonoda shows antenna 20 mounted to transparent plate 5, which forms the front face of Sonoda’s device over display member 11.” Appeal Br. 10; Reply Br. 7–8. Nevertheless, the Examiner relies on Sonoda, in combination with Zhang, to teach or suggest, “conductive traces mounted on the dielectric member that receive wireless signals through the dielectric member.” Final Act. 9–10. In particular, the Examiner relies on Zhang to teach or suggest “a dielectric member opposite the display cover layer that forms a rear surface of the electronic device opposite the front surface.” Id. (citing Zhang ¶ 39); Ans. 7 (citing Zhang, Figs. 3B, 5A); see Zhang, Fig. 4A (dielectric portions 12-2A and 12-2B). Thus, we agree that the combined teachings of Zhang and Sonoda teach or suggest the disputed limitation. We are not persuaded the Examiner errs in rejecting claim 8 as obvious over the combined teachings of Zhang and Sonoda, and we sustain that rejection. Further, Appellant does not challenge the obviousness Appeal 2020-006645 Application 15/424,605 22 rejection of dependent claims 9, 10, 13, and 14 separately from its challenge to their base claim, independent claim 8; and, therefore, we also sustain the rejection of those claims. C. Obviousness Over Zhang, Sonoda, and Hill As noted above, the Examiner rejects claims 11 and 12 as obvious over the combined teachings of Zhang, Sonoda, and Hill. Final Act. 13–14. Appellant does not challenge the obviousness rejection of dependent claims 11 and 12 separately from its challenge to their base claim, independent claim 8. See Appeal Br. 13. Therefore, because we sustain the obviousness rejection of claim 8, we also sustain the rejection of these claims. DECISION 1. The Examiner did not err in rejecting: a. claims 1–7 and 15–20 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Zhang and Hill; b. claims 8–10, 13, and 14 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Zhang and Sonoda; and c. claims 11 and 12 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Zhang, Sonoda, and Hill. 2. Thus, on this record, claims 1–20 are not patentable. CONCLUSION We affirm the Examiner’s rejections of claims 1–20.
