SMEGAL, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Kristopher Smith et al. (Appellants) seek our review under 35 U.S.C. § 134 of the Examiner’s rejection2 under 35 U.S.C. § 103(a) of claims 1—8, 16, and 173 as obvious overNanba (US 7,540,278 B2, iss. June 2, 2009) and 1 According to Appellants, the real party in interest is Continental Automotive Systems, Inc. Appeal Br. 1. 2 Appeal is taken from the adverse decision of the Examiner as set forth in the Final Office Action, dated April 10, 2014 (“Final Act.”). 3 While listing claims 16 and 17 among the rejected claims on page 1 of the Final Action, the Examiner does not include claims 16 and 17 in this rejection in the Final Action. See Final Act. 2. The Examiner notes, however, that claims “9-12, 14 and 16-19 ... are rejected for the grounds previously presented.” Id. at 7. Appellants argue as if these claims 16 and Appeal 2015-005472 Application 12/997,350 Gozdawa (US 6,471,404 Bl, iss. Oct. 29, 2002); and of claims 9—12, 14, 18, and 19* * * 4 as obvious over Crow (US 3,961,769, iss. June 8, 1976), Nanba, and Gozdawa. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. CLAIMED SUBJECT MATTER Claims 1 and 9 are independent. Claim 1 is reproduced below and illustrates the claimed subject matter, with disputed limitations emphasized. 1. An Exhaust Gas Recirculation (EGR) valve assembly comprising: a rotatable shaft supported within a housing; and a flap attached to the shaft and rotatable within the housing for controlling flow through a passage defined within the housing, wherein the shaft includes an integrally formed collar disposed outside of the passage that fixes an axial position of the flap within the passage. ANALYSIS Obviousness of Claims 1—8, 16, and 17 over Nanba and Gozdawa Appellants argue claims 1—8, 16, and 17 together in contesting the rejection of these claims as obvious over Nanba and Gozdawa. See Appeal Br. Reply Br. 1—3. We select claim 1 as the representative claim for this group, and the remaining claims stand or fall with claim 1. See 37 C.F.R. § 41.37(c)(l)(iv). 17 are included in the first ground. See Appeal Br. 2, 4, 7; Reply Br. 3. Therefore, we consider the omission of claims 16 and 17 from the statement of the rejection to be an inadvertent error. 4 We correct the Examiner’s inadvertent inclusion of claim 15 in this rejection as it was canceled in an amendment filed February 12, 2014, (see Final Act. 4). 2 Appeal 2015-005472 Application 12/997,350 The Examiner finds that Nanba discloses an Exhaust Gas Recirculation (EGR) valve assembly including, inter alia, a rotatable shaft within a housing, but that Nanba’s shaft does not include “an integrally formed collar disposed outside of the passage that fixes an axial position of the flap within the passage.”5 Final Act. 2. However, the Examiner also finds that Gozdawa “discloses a shaft (1) having a collar (la) arranged such that the collar has an integrally formed extended diameter larger than the inner diameter of a bearing (2),” which “acts to restrain axial displacement of the shaft.” Id. at 2—3 (citing Gozdawa, col. 4,1. 60 to col. 8,1. 32). Based on the foregoing, the Examiner determines that it would have been obvious “to include a shaft having an integrally formed collar as taught by Gozdawa in the system of Nanba since it is known [] from Gozdawa that such an arrangement restrains axial movement of the shaft,” and “[i]t is readily apparent to place the collar outside the passage in order to provide this functionality.” Id. at 3. In taking issue with the analysis and conclusions presented in the Final Office Action, Appellants reason that the shaft of Nanba is “supported for rotation by ball bearing 39,” so that “shaft 2 is fixed axially and can only rotate radially.” Appeal Br. 3. Appellants then contend that to modify “the fixed shaft [of Nanba] with the floating bearing configuration disclosed in Gozdawa . . . would change the intended operation of Nanba and therefore teach away from the proposed combination.” Id.; see also Reply Br. 2—3. 5 Nanba teaches ball bearing 39 that fixes the axial position of shaft 2 along with the butterfly valve (flap) 1. See Nanba, col. 8,11. 9-43. 3 Appeal 2015-005472 Application 12/997,350 Without referring to any limitation of claim 1, Appellants also contend that “[t]he modification to Nanba proposed by the Examiner would require a constant flow of gases to provide the required support of the bearing as is shown in Gozdawa,” but that “because the Nanba device is a valve, such flow is not always available, and may vary depending on a position of the valve,” concluding that “the bearing configuration disclosed in Gozdawa for a constantly rotating shaft teaches away from use with a valve such as is disclosed in the base reference of Nanba.” Appeal Br. 3^4. Still further, Appellants contend that “the addition of a bearing relying on the flow of gases as is shown in Gozdawa destroys the intended operation of the Nanba valve.” Id. at 4; see also Reply Br. 3. However, we find Appellants’ contentions to be unpersuasive, first because they appear to rely upon the bodily incorporation of Gozdawa into Nanba, which is not the standard for an obviousness rejection. As the Examiner explains, “Gozdawa was relied on solely to teach a collar on the shaft, and has NOT [been] bodily incorporated into Nanba.” Ans. 7. Thus, we agree with the Examiner that the use of a portion of Gozdawa’s teaching is appropriate in that all of the features of a secondary reference need not be bodily incorporated into the primary reference. See In re Keller, 642 F.2d 413,425 (CCPA 1981). In addition, as the Examiner explains, “the prior art’s mere disclosure of more than one alternative does not constitute a teaching away from any of these alternatives because such disclosure does not criticize, discredit, or otherwise discourage the solution claimed” Final Act. 8—9. See In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Thus, Appellants’ contentions are unavailing as they are not commensurate with the scope of 4 Appeal 2015-005472 Application 12/997,350 claim 1, which merely recites “a rotatable shaft supported within a housing.” See Appeal Br. 8, Claims App. As we are instructed by our reviewing court, “limitations are not to be read into the claims from the [Specification.” In re Van Geuns, 988 F.2d 1181, 1184 (Fed. Cir. 1993) (citing In reZletz, 893 F.2d 319, 321 (Fed. Cir. 1989)). The Examiner also points out that “Gozdawa aims to fix axial movement of a rotatable shaft (column 4, lines 63-67), which . .. would actually achieve the purpose of placing the collar on the shaft according to Appellant’s disclosure,” and “would not destroy Nanba in any way according to Appellants’ argument.”6 Id. Furthermore, we note that “[cjlaims may be obvious in view of a combination of references, even if the features of one reference cannot be substituted physically into the structure of the other reference.” Orthopedic Equip. Co. v. U.S., 702 F.2d 1005, 1013 (Fed. Cir. 1983) (citation omitted). Thus, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR Int 7 Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007). Summarizing the foregoing, we find that the Examiner’s findings and conclusions are supported by the record and based on rational underpinnings. See Ans. 6—9. Moreover, Appellants do not provide any evidence or argument sufficient to show that the proposed modification would have been beyond the level of ordinary skill in the art. Neither do 6 The Specification discloses (paragraph 4) that “[bjecause the collar fixes the axial position of the shaft, axial movement of the flap and a sealing ring relative to the valve seat is eliminated or significantly reduced.” 5 Appeal 2015-005472 Application 12/997,350 Appellants provide any persuasive evidence or argument sufficient to show that the proposed modification would have been more than a predictable use of the prior art elements according to their established functions. “The combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” KSR, 550 U.S. at 416. “If a person of ordinary skill can implement a predictable variation, §103 likely bars its patentability.” Id. at 417. Accordingly, we sustain the Examiner’s rejection of independent claim 1 as unpatentable over Nanba and Gozdawa. We further sustain the rejection of dependent claims 2—8, 16, and 17, which fall with claim 1. Obviousness of Claims 9—12, 14, 18, and 19 over Crow, Nanba, and Gozdawa Appellants argue claims 9—12, 14, 18, and 19 together in contesting the rejection of these claims as obvious over Crow, Nanba, and Gozdawa. See Appeal Br. 4—6; Reply Br. 3—5. We select claim 9 as the representative claim for this group, and the remaining claims stand or fall with claim 9. See 37 C.F.R. § 41.37(c)(l)(iv). While looking to Crow for disclosing substantially all the limitations of claim 9,7 the Examiner acknowledges that Crowe lacks, inter alia, “a gap disposed between one of the first bearing and the second bearing communicating with the passage to generate a pressurized region between the collar and at least one of the first and second bearings.” Final Act. 5. However, the Examiner observes that Gozdawa “discloses a gap between 7 Citing Crowe, col. 1,1. 55 to col. 3,1. 13. 6 Appeal 2015-005472 Application 12/997,350 first and second bearing surfaces communicating with a passage to generate a pressurized region between the collar and the bearing.” Id. (citing Gozdawa, col. 4,1. 60 to col. 8,1. 32). From the foregoing, the Examiner reasons that “because the shaft [of Gozdawa] is not sealed and must be smaller than the housing to be able to rotate, pressurized flow from the passage to the bearing region around the collar is inherently present and would lead to the claimed result of the invention according to the combination of references.” Id. at 6. We agree. In addition to repeating arguments that we found not demonstrative of error in the Examiner’s rejection of claim 1, as set forth supra, Appellants contend that “Gozdawa discloses inlets 21 and 30 [that are] from a separate high pressure source, and not from a passage through which the shaft extends as is required by claim 9.” Appeal Br. 5 (appearing to cite Gozdawa, col. 6,11. 45—50). However, the presence of additional structure in Gozdawa, such as inlets 21 and 30, does not undermine the rejection where claim 9 uses an open-ended transition “comprising.” See Exergen Corp. v. Wal-Mart Stores, Inc., 575 F.3d 1312, 1319 (Fed. Cir. 2009) (“The claim uses the term ‘comprising,’ which is well understood in patent law to mean ‘including but not limited to.’” (citing CIAS, Inc. v. Alliance Gaming Corp., 504 F.3d 1356, 1360 (Fed. Cir. 2007)). Furthermore, we find the Examiner’s use of a portion of Gozdawa’s teaching to be appropriate in that all of the features of a secondary reference need not be bodily incorporated into the primary reference. See In re Keller, 642 F.2d 413, 425 (CCPA 1981). Appellants also contend that “Nanba fails to disclose any collar at all and therefor no pressurized region between a collar and bearing is taught.” 7 Appeal 2015-005472 Application 12/997,350 Appeal Br. 5. However, we previously found this contention to be unpersuasive of Examiner error in sustaining the rejection of claim 1, supra. As the Examiner explains, “Nanba was relied upon solely for the teaching of a seal on the valve flap.” Ans. 12. Appellants continue by contending that “the enormous weight of the disclosed valve in Crow teaches away from the formation of such a pressurized region as the weight of the valve would require load bearing contact with the bearing 42.” Appeal Br. 6. Appellants then conclude that “[t]he structure and intended operation of Crow therefore teaches away from the inclusion of any gap or pressure balance operation as is disclosed in Gozdawa.” Id. at 6. However, the Examiner reasons that “Crow does not discourage or discredit or otherwise teach away from significantly downsizing the valve, and actually discusses a wide range of sizes,” so that “while it may be true that a large valve may have a significant weight, it is readily apparent that the much smaller version would be significantly lighter.” Ans. 10. We agree, noting that “[attorney arguments in a brief cannot take the place of evidence.” In re Pearson, 494 F.2d 1399, 1405 (CCPA 1974) (citation omitted); see also In re De Blauwe, 736 F.2d 699, 705 (Fed. Cir. 1984) (holding that lawyer arguments and conclusory statements which are unsupported by factual evidence are entitled to little probative value). Accordingly, we sustain the Examiner’s rejection of independent claim 9 as unpatentable over Crow, Nanba and Gozdawa. We further sustain the rejection of dependent claims 10-12, 14, 18, and 19, which fall with claim 9. 8 Appeal 2015-005472 Application 12/997,350 DECISION We AFFIRM the Examiner’s rejections. 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).
