ANKENBRAND, JEFFREY R. SNAY, and MERRELL C. CASHION, JR., Administrative Patent Judges. CASHION, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Pursuant to 35 U.S.C. § 134(a), Appellant1 appeals from the Examiner’s decision to reject claims 1–9 and 11–20. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies the real party in interest as “VALEO EQUIPEMENTS ELECTRIQUES MOTEUR.” Appeal Br. 3. Appeal 2020-002808 Application 15/104,802 2 The invention relates to an interconnector that improves the performance of a stator in connecting the phases of the polyphase electrical machine. Spec. ¶¶ 1, 6, 18. The Specification describes that the inventive interconnector distributes the inputs and the outputs of the coils in the stator on both sides of the body of the stator, leaving more space for the welding operations. Spec. ¶ 45. Claim 1 illustrates the invention and is reproduced below: 1. An interconnector (22) for a stator (11) of a polyphase rotary electrical machine, the stator (11) comprising a stator body (12) supporting a winding including a plurality of coils (19), each of the coils (19) having input (191) and output (192) ends, the interconnector (22) comprising: a first part (22a) comprising at least three phase conductors (32-34) each having an annular form, the at least three phase conductors (32-34) stacked axially on one another and insulated electrically against one another; and a second part (22b) comprising at least one neutral conductor (31) having an annular form and insulated electrically; the first part (22a) and the second part (22b) mounted on axially opposite sides of the stator body (12), each of the at least three annular phase conductors (32-34) of the first part (22a) and the at least one annular neutral conductor (31) of the second part (22b) provided on an inner periphery thereof with lugs (36) projecting towards an interior of the interconnector (22) for welding respectively of the input ends (191) and the output ends (192) of the coils. Appellant requests review of the following rejections from the Examiner’s Final Office Action dated February 19, 2019: Appeal 2020-002808 Application 15/104,802 3 I. Claims 1, 2, 4, 5, 8, 9, 12–16, 18, and 20 rejected under 35 U.S.C. § 103 as unpatentable over Hashimoto (JP 2008-312276 A, published December 25, 2008),2 Otsuji (US 2008/0242124 A1, published October 2, 2008), and Inoue (WO 2012/029706 Al, published March 8, 2012).3 II. Claims 3, 17, and 19 rejected under 35 U.S.C. § 103 as unpatentable over Hashimoto, Otsuji, Inoue, and Haydock (US 6,271,608 B1, issued August 7, 2001). III. Claims 6 and 7 rejected under 35 U.S.C. § 103 as unpatentable over Hashimoto, Otsuji, Inoue, and Kinoshita (US 2007/0273221, published November 29, 2007). IV. Claim 11 rejected under 35 U.S.C. § 103 as unpatentable over Hashimoto, Otsuji, Inoue, and Yamaguchi (US 2010/0096943 Al, published April 22, 2010). Appellant presents arguments only for independent claim 1 and dependent claim 4. Appellant does not present separate arguments for the rejections of the remaining claims. Accordingly, we select claims 1 and 4 as representative of the subject matter claimed and decide the appeal as to all grounds of rejections based on the arguments presented for claims 1 and 4. 2 Appellant brought to our attention a translation of the primary reference to Hashimoto that appears to be more accurate than the translation the Examiner relies upon in the Final Action. Specifically, Appellant directs us to worldwide.espacenet.com (European Patent Office) for access to this translation. Reply Br. 3. This particular translation was made of record by Appellant on June 15, 2016. Because Appellant relies on this version of the translation to refute the Examiner’s reasoning on certain issues (Appeal Br. 3–4), we also rely on this translation for the purposes of this opinion. 3 The Examiner relies on an English machine translation of Inoue dated August 1, 2018. Appeal 2020-002808 Application 15/104,802 4 OPINION After review of the respective positions the Appellant provides in the Appeal and Reply Briefs and the Examiner provides in the Final Action and the Answer, we affirm the Examiner’s prior art rejections of claims 1–9 and 11–20 based on the fact-finding and the reasons the Examiner provides. We add the following. Independent claim 1 Claim 1 recites an interconnector for a stator of a polyphase rotary electrical machine having (1) a first part comprising at least three phase conductors with each conductor having an annular form and with at least three phase conductors stacked axially on one another and (2) a second part comprising at least one neutral conductor having an annular form. The Examiner finds that Hashimoto discloses an interconnector comprising a first part having at least three annular phase conductors stacked radially. Final Act. 5–7; Ans. 4; Hashimoto Figures 5, 8, 12, ¶¶ 42. The Examiner also finds that Hashimoto teaches a second part comprising at least one conductor having an annular form and that Hashimoto’s first and second parts are mounted on axially opposite sides of a stator body. Final Act. 7. The Examiner finds that Hashimoto does not teach (1) stacking the three phase annular conductors axially and (2) the at least one conductor of the second part as a neutral conductor. Id. at 8. Regarding difference (1), the Examiner finds Otsuji discloses it was known to arrange conductors by stacking them axially to form a structure of a busbar unit that supplies current to an armature of a motor. Final Act. 8; Otsuji Figure 11, ¶¶ 2, 4, 60–61. Regarding difference (2), the Examiner finds Inoue describes use of Appeal 2020-002808 Application 15/104,802 5 a neutral conductor in a three phase stator that is configured so that surfaces of its connection portions are in close proximity to planar surfaces of the coil star portions of conductor wires. Final Act. 8; Inoue ¶¶ 49–54. The Examiner determines that it would have been obvious to one of ordinary skill in the art to modify Hashimoto’s interconnector by arranging Hashimoto’s conductors axially instead of radially, as Otsuji teaches, and by providing a neutral conductor to Hashimoto’s stator, as Inoue teaches, to arrive at the claimed invention. Final Act. 8–9. Appellant argues that Hashimoto does not disclose busbars in annular form as the Examiner contends. Appeal Br. 8. According to Appellant, the claim term “annular form,” when read in light of the Specification and Application Figures 3–5, refers to a circular form as an example. Appeal Br. 8; Spec. ¶¶ 20, 21, 29. That is, Appellant contends that the claimed conductors are “closed type” conductors, whereas Hashimoto discloses busbars (conductors) of an “open type” with each comprising a supply terminal and a coil connection terminal spaced from the supply terminal. Appeal Br. 8; see Hashimoto Figures 4 and 8. Appellant further contends that Hashimoto specifically discloses that “the busbars 51 to 53 are not annular and are of an open type provided with openings, material costs can be reduced as compared with the case where each of the busbars 51 to 53 is of a closed type.” Reply Br. 3–4; Hashimoto ¶ 42. Appellant’s arguments do not identify reversible error in the Examiner’s determination of obviousness. As the Examiner explains in the Answer, when read as a whole, Hashimoto describes an alternate embodiment in which the phase conductors are made more circular. Ans. 4. In fact, Hashimoto expressly discloses that Appeal 2020-002808 Application 15/104,802 6 “[e]ach bus bar 51 to 54 shown in the figure has a polygonal shape, but each may have a circular shape.” Hashimoto ¶ 50. Thus, Hashimoto’s disclosure appears to encompass the use of “open type,” as well as “closed type” conductors. While Hashimoto focuses on describing an embodiment having “open type” conductors, this appears to be a preferred embodiment. It is well settled that a reference may be relied upon for all that it discloses and not merely the preferred embodiments as Appellant suggests. See Merck & Co., Inc. v. Biocraft Labs., Inc., 874 F.2d 804, 807 (Fed. Cir. 1989) (“[A]ll disclosures of the prior art, including unpreferred embodiments, must be considered.” (quoting In re Lamberti, 545 F.2d 747, 750 (CCPA 1976))); In re Fracalossi, 681 F.2d 792, 794 n.1 (CCPA 1982) (explaining that a prior art reference’s disclosure is not limited to its examples). Appellant has not explained adequately why Hashimoto’s preferred embodiment limits the broader disclosure of using circular conductors. Appellant argues Otsuji does not disclose annular busbars but, instead, discloses a plurality of busbars arranged in an axial direction that may be embedded in a busbar holder by insertion molding. Appeal Br. 7; Otsuji ¶¶ 60–61. Appellant further contends that Otsuji’s Figures 2, 3, and 7 show that the busbars are approximately semi-circular and not annular. Appeal Br. 7–8. Thus, Appellant asserts the combination of Hashimoto and Otsuji would result in an interconnector lacking the annular phase conductors. Id. at 8. Appellant’s arguments are not persuasive of reversible error in the Examiner’s determination of obviousness. As the Examiner explains in the Answer, Otsuji was cited to teach that it is known to arrange busbars axially to form a busbar unit for a motor. Appeal 2020-002808 Application 15/104,802 7 Ans. 4. In fact, Otsuji discloses that busbars in a busbar unit can be arranged radially or axially. Otsuji Figures 5 (radial orientation), 11 (axial orientation), ¶¶ 37, 60–61. Thus, Otsuji teaches the axial arrangement of busbars as a well-known alternative to the radial arrangement of busbars. Given this disclosure, Appellant fails to explain why one skilled in the art, using no more than ordinary creativity, would not have been capable rearranging Hashimoto’s conductors axially and still reasonably expect that such an arrangement would be suitable for Hashimoto’s purposes. 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.”); see also In re Sovish, 769 F.2d 738, 743 (Fed. Cir. 1985) (presuming skill on the part of one of ordinary skill in the art); In re O'Farrell, 853 F.2d 894, 904 (Fed. Cir. 1988) (“For obviousness under § 103, all that is required is a reasonable expectation of success.”). While Appellant contends that Otsuji does not disclose “closed type” conductors, Appellant fails to direct us to any disclosure of Otsuji that expressly limits axial arrangement of conductors to only “open type” conductors. Appellant next argues Inoue does not disclose at least three phase conductors (or busbars) each having an annular form nor the claimed connector for a stator of a rotary electrical machine comprising the phase conductors (or busbars) each having an annular form. Appeal Br. 9. As the Examiner explains in the Answer, Inoue teaches that it was known to use a neutral conductor in combination with a connector in a stator. Ans. 5. We note that the Specification also acknowledges it was known to use neutral conductors in stators. Spec. ¶ 32 (citing to EP 0 831 580 A2). While Appellant contends that Inoue’s connector is not a three Appeal 2020-002808 Application 15/104,802 8 phase connector (Reply Br. 6–7), Appellant fails to explain why a specific type of connector would lead one skilled in the art away from using a neutral connector in a stator given that the prior art shows it is common to do so. Moreover, busbar conductor 54 in Hashimoto’s Figure 11 comprises coil connections (54c) spaced closely and equally from each other compared to the coil connections of busbar conductors 51–53 in Hashimoto’s Figures 10 and 12 (for example, connector 53c coil connections). Furthermore, Hashimoto’s busbar conductor/coil connections shown in Figure 11 appear similar in structure to neutral conductor (28) shown in Inoue’s Figure 3 in that they both provide coil connections (54c, 28a) in similar arrangement (spaced closely and equally from each other). One skilled in the art would have reasonably inferred from these disclosures that Hashimoto’s busbar conductor 54 functions as a neutral connector or would have been capable of functioning as such. KSR, 550 U.S. at 418 (“[T]he [obviousness] analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.”); see also In re Fritch, 972 F.2d 1260, 1264–65 (Fed. Cir. 1992) (holding that a reference stands for all of the specific teachings thereof as well as the inferences one of ordinary skill in the art would have reasonably been expected to draw therefrom). Claim 4 Claim 4 recites that the first part of the interconnector comprises more than three annular phase conductors. Appeal 2020-002808 Application 15/104,802 9 The Examiner finds Otsuji teaches an interconnector can comprise more than three phase conductors. Final Act. 9; Otsuji Figure 11; ¶¶ 60, 62. We have considered Appellant’s arguments with respect to the rejection of claim 4 (Appeal Br. 10–11), but find them unpersuasive of reversible error in the Examiner’s conclusion of obviousness. As the Examiner notes, Otsuji discloses “the number of the busbars and/or the number of the wire connector portions can be changed based on the numbers of the phases and the slots of the brush less motor.” Ans. 5; Otsuji ¶ 62. Appellant does not address the Examiner’s reasoning in the Reply Brief. Therefore, we discern no error in the Examiner’s conclusion that that it would have been obvious to modify Hashimoto’s interconnector to comprise more than three annular phase conductors. See In re Harza, 274 F.2d 669, 671 (CCPA 1960) (“It is well settled that the mere duplication of parts has no patentable significance unless a new and unexpected result is produced, and we are of the opinion that such is not the case here.”). Absent a showing of new or unexpected results, Appellant has not adequately explained why one skilled in the art would not have been capable of modifying Hashimoto’s interconnector to provide more than three annular phase conductors if so desired. Arguments not specifically addressed are deemed not persuasive for the reasons the Examiner presents. Accordingly, we affirm the Examiner’s prior art rejections of claims 1–9 and 11–20 for the reasons the Examiner presents and those we give above.
