TIMM, BEVERLY A. FRANKLIN, and JANE E. INGLESE, Administrative Patent Judges. INGLESE, Administrative Patent Judge. DECISION ON APPEAL Appellant1 requests our review under 35 U.S.C. § 134(a) of the Examiner’s decision to finally reject claims 1, 2, 5—10, and 12—19. We have jurisdiction over this appeal under 35 U.S.C. § 6(b). We AFFIRM-IN-PART. 1 Appellant is the Applicant, SEAGATE TECHNOLOGY LLC, which, according to the Appeal Brief, is the real party in interest. Appeal Brief filed May 16, 2016 (“App. Br.”), 1. Appeal 2017-005526 Application 13/722,632 STATEMENT OF THE CASE Appellant claims a perpendicular data recording medium. Br. 2—\. Claims 1 and 10 illustrate the subject matter on appeal and are reproduced below: 1. A perpendicular data recording medium, comprising: a multi-layer recording structure formed on a base substrate and adapted to magnetically store a magnetic bit sequence in domains substantially perpendicular to said layers; a single-layer magnetic stabilization structure contactingly disposed on the multilayer recording structure to magnetically stabilize an upper portion of the multi-layer recording structure, the single-layer magnetic stabilization structure characterized as a single layer of hard magnetic material having a non-zero boron (B) content of less than about 6% and a platinum (Pt) content of about 20—25%; and a protective overcoat layer contactingly disposed on the single layer magnetic stabilization structure. 10. A perpendicular data recording medium, comprising: a multi-layer recording structure adapted to magnetically store a magnetic bit sequence in domains substantially perpendicular to said layers; a thin hard magnetic layer contactingly disposed on the multi layer recording structure to magnetically stabilize an upper portion of the recording structure, the thin hard magnetic layer formed of only a single layer of hard magnetic material and having an overall thickness of 10% or less of an overall thickness of the multi-layer recording structure, the single layer of hard magnetic material further having a thickness of less than 1% of a topmost recording layer of the recording structure; and 2 Appeal 2017-005526 Application 13/722,632 a protective overcoat layer contactingly disposed on the thin hard magnetic layer. App. Br. 16—18 (Claims Appendix) (emphasis added). The Examiner sets forth the following rejections in the Final Office Action entered December 1, 2015 (“Final Act.”), and maintains the rejections in the Examiner’s Answer entered December 6, 2016 (“Ans.”): I. Claims 1, 2, 5—9, 18, and 19 under 35 U.S.C. § 103(a) as unpatentable over Kong et al. (US 2009/0197119 Al, published August 6, 2009) in view of Berger et al. (US 2009/0080110 Al, published March 26, 2009); II. Claims 10 and 15—17 under 35 U.S.C. § 103(a) as unpatentable over Kong in view of Nishikawa et al. (US 2004/0209037 Al, published October 21, 2004); and III. Claims 12—14 under 35 U.S.C. § 103(a) as unpatentable over Kong in view of Nishikawa and Berger. DISCUSSION Upon consideration of the evidence relied upon in this appeal and each of Appellant’s contentions, we affirm the Examiner’s rejection of claims 1,2, 5—9, 18, and 19 under 35 U.S.C. § 103(a) for the reasons set forth in the Final Action, the Answer, and below, and reverse the Examiner’s rejections of claims 10 and 12—17 under 35 U.S.C. § 103(a) for the reasons set forth in the Appeal Brief and below. We review appealed rejections for reversible error based on the arguments and evidence the Appellant provides for each issue the Appellant identifies. 37 C.F.R. § 41.37(c)(l)(iv); Ex parte Frye, 94 USPQ2d 1072, 3 Appeal 2017-005526 Application 13/722,632 1075 (BPAI 2010) (precedential) (cited with approval in In re Jung, 637 F.3d 1356, 1365 (Fed. Cir. 2011) (explaining that even if the examiner had failed to make a prima facie case, “it has long been the Board’s practice to require an applicant to identify the alleged error in the examiner’s rejections”)). Rejection I Claims 1, 2, 6—9, 18, and 19 Appellant argues claims 1, 2, 6—9, 18, and 19 together on the basis of claim 1, to which we limit our discussion. Br. 6—11; 37 C.F.R. § 41.37(c)(l)(iv). Kong discloses a perpendicular magnetic recording medium 100 formed by sequentially stacking a soft magnetic layer 130, an underlayer 150, and a recording layer 160 (multi-layer recording structure) on a substrate 110 (base substrate). Kong |34; Fig. 1. Kong discloses forming a protective layer 170 (protective overcoat layer) over the recording layer 160. Kong || 24, 26; Fig. 1. Kong discloses that the recording layer 160 has a three-layer structure comprised of a first ferromagnetic layer 161, a second ferromagnetic layer 163, and a capping layer 169 (single-layer magnetic stabilization structure). Kong 161; Fig. 1. Kong discloses that the capping layer 169 thermally stabilizes the first and second ferromagnetic layers 161, 163, and may be formed of a CoCrPtB alloy. Kong | 64. The Examiner finds that Kong does not disclose the boron and platinum content of the capping layer, and the Examiner relies on Berger for suggesting this feature. Final Act. 3. Berger discloses a perpendicular magnetic recording medium 200 comprising a multilayer cap structure 230 (magnetic stabilization structure) coupled to a granular layer 210 (recording 4 Appeal 2017-005526 Application 13/722,632 structure). Berger || 8, 33; Fig. 2. Berger discloses that the multilayer cap structure 230 is formed of lower 232 and upper 236 magnetic layers comprised of a CoCrPtB alloy that includes 0.1—30 atomic % platinum, and 0.1—20 atomic % boron. Berger || 33, 37; Fig. 2. The Examiner finds that one of ordinary skill in the art would have been led at the time of Appellant’s invention to modify the capping layer 169 formed of a CoCrPtB alloy disclosed in Kong to include platinum and boron in the amounts utilized in the magnetic layers 232, 236 of the multilayer cap structure 230 disclosed in Berger, because Berger discloses that “this is a known material” for a CoCrPtB alloy magnetic capping structure. Final Act. 3. Appellant argues that Berger “explicitly and exclusively teaches a multi-layer capping structure contacting a single recording layer,” and fails to disclose “a single layer magnetic layer having the claimed boron and platinum content contacting a multi-layer recording structure.” Br. 6—7. (citations omitted). Appellant further contends that the magnetic layers disclosed in Berger having a platinum and boron content as recited in claim 1 are used only in combination with non-magnetic layers to allow adequate exchange coupling. Br. 8. Appellant asserts that Berger therefore teaches away from utilizing the recited platinum and boron content in a single magnetic layer to stabilize a portion of a recording structure. Id. However, Appellant’s arguments are unpersuasive of reversible error because they are improperly based on Berger alone, and do not take into consideration what the combined disclosures of Kong and Berger would have suggested to one of ordinary skill in the art at the time of Appellant’s invention. In re Merck & Co., Inc., 800 F.2d 1091, 1097 (Fed. Cir. 1986) (“Non-obviousness cannot be established by attacking references 5 Appeal 2017-005526 Application 13/722,632 individually where the rejection is based upon the teachings of a combination of references.”); In re Keller, 642 F.2d 413, 425 (CCPA 1981) (The test for obviousness “is what the combined teachings of the references would have suggested to those of ordinary skill in the art.”) As discussed above, Kong discloses a perpendicular magnetic recording medium 100 that includes a recording layer 160 having first and second ferromagnetic layers 161, 163, and a capping layer 169 that thermally stabilizes the ferromagnetic layers 161, 163. Accordingly, Kong—rather than Berger—discloses a single capping layer 169 that contacts and thermally stabilizes a multilayer recording structure, corresponding to a single-layer magnetic stabilization structure as recited in claim 1. Although Kong discloses that the capping layer 169 may be formed of a CoCrPtB alloy, Kong does not disclose the composition of the alloy, leaving it to one of ordinary skill in the art to identify a suitable CoCrPtB alloy. Berger’s disclosure of the suitability of a CoCrPtB alloy that includes 0.1—30 atomic % platinum and 0.1—20 atomic % boron for forming a cap structure contacting a granular layer 210 (recording structure) in a perpendicular magnetic recording medium reasonably would have led one of ordinary skill in the art to utilize such a CoCrPtB alloy to form Kong’s single capping layer 169. Although Berger discloses that the lower 232 and upper 236 magnetic layers of the multilayer cap structure 230 are flanked by layers of non magnetic material 234, 238, the presence of the non-magnetic material layers does not negate Berger’s disclosure of the suitability of a CoCrPtB alloy including 0.1—30 atomic % platinum and 0.1—20 atomic % boron for 6 Appeal 2017-005526 Application 13/722,632 forming magnetic layers 232, 236 of a multi-layer cap structure 230. Berger Tflf33, 37. Accordingly, contrary to Appellant’s arguments, Berger does not teach away from utilizing a CoCrPtB alloy including 0.1—30 atomic % platinum and 0.1—20 atomic % boron to form Kong’s a single layer capping layer 169 (magnetic stabilization structure) because Berger does not criticize or discredit use of such an alloy for forming a single capping layer that contacts a multilayer recording structure, as disclosed in Kong. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004) (“[t]he 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”); In re Gurley, 27 F.3d 551, 552-53 (Fed. Cir. 1994). Appellant further argues that Kong discloses that the capping layer 169 decreases the magnetization field of the first and second ferromagnetic layers of Kong’s recording structure 160. Br. 7. Appellant contends that Kong’s capping layer 169 therefore teaches away from the single-layer magnetic stabilization structure recited in claim 1, which increases magnetic saturation as explained in Appellant’s Specification, and magnetically stabilizes an upper portion of the multi-layer recording structure as recited in claim 1. Br. 7 (citing Spec. 10,11. 1—12). However, Appellant’s arguments are again unpersuasive of reversible error because they are improperly based on Kong alone, and do not take into consideration what the combined disclosures of Kong and Berger would have suggested to one of ordinary skill in the art at the time of Appellant’s invention. Merck, 800 F.2d at 1097; Keller, 642 F.2d at 425. 7 Appeal 2017-005526 Application 13/722,632 As discussed above, Berger’s disclosure of a multilayer cap structure 230 comprising magnetic layers 232, 236 formed of a CoCrPtB alloy that includes 0.1—30 atomic % platinum and 0.1—20 atomic % boron coupled to a granular layer 210 (recording structure), reasonably would have led one ordinary skill in the art to utilize such a CoCrPtB alloy to form Kong’s single layer capping layer 169. Therefore, although Kong may disclose that capping layer 169 decreases the magnetization field of the first and second ferromagnetic layers of Kong’s recording layer 160, the proposed combination of the applied prior art utilizes a CoCrPtB alloy as disclosed in Berger—rather than the CoCrPtB alloy disclosed in Kong—to form Kong’s capping layer 169. Consequently, Kong does not teach away from utilizing a CoCrPtB alloy including 0.1—30 atomic % platinum and 0.1—20 atomic % boron as disclosed in Berger to form Kong’s a single layer capping layer 169 (magnetic stabilization structure), because Kong does not criticize or discredit use of such an alloy for forming a single layer capping layer that contacts a multilayer recording structure. Fulton, 391F.3datl201; Gurley, 27 F.3d at 552-53. Because a combination of the relied-upon disclosures in Kong and Berger would have suggested a single capping layer having a composition and structure that appears to be the same as, or substantially similar to, the single-layer magnetic stabilization structure recited in claim 1, a reasonable basis exists for determining that the suggested single capping layer would possess the same characteristics or attributes as the recited single-layer magnetic stabilization structure, including magnetically stabilizing an upper portion of the multi-layer recording structure, as recited in claim 1. PAR Pharm., Inc. v. TWIPharm., Inc., 773 F.3d 1186, 1195 (Fed. Cir. 2014) 8 Appeal 2017-005526 Application 13/722,632 (concept of inherency, when applied to obviousness, is present “when the limitation at issue is the ‘natural result’ of the combination of prior art elements”); In re Spada, 911 F.2d 705, 709 (Fed. Cir. 1990) (explaining that a chemical composition and its properties are inseparable.). Therefore, the burden shifts to Appellant to show otherwise. In re Best, 562 F.2d 1252, 1255 (CCPA 1977) (“Where ... the claimed and prior art products are identical or substantially identical, or are produced by identical or substantially identical processes, the PTO can require an applicant to prove that the prior art products do not necessarily or inherently possess the characteristics of his claimed product.”); In re Crish, 393 F.3d 1253, 1259 (Fed. Cir. 2004) (“[W]hen the prior art evidence reasonably allows the PTO to conclude that a claimed feature is present in the prior art, the evidence ‘compels such a conclusion if the applicant produces no evidence or argument to rebut it.’” (quoting Spada, 911 F.2d at 708 n.3)). Appellant does not direct us to any persuasive evidence or reasoning demonstrating that Kong’s single capping layer formed of a CoCrPtB alloy that includes 0.1—30 atomic % platinum and 0.1—20 atomic % boron as disclosed in Berger would not magnetically stabilize an upper portion of Kong’s multi-layer recording structure, as recited in claim 1. Br. 6—11. Therefore, Appellant’s arguments are unpersuasive of reversible error. Appellant further argues that one of ordinary skill in the art would “point to the contradicting purposes of Kong and Berger as evidence of no reasonable motivation to combine the references.” Br. 6—7. Appellant contends that the Examiner, therefore, “engaged in blatant improper hindsight reconstruction.” Br. 11. 9 Appeal 2017-005526 Application 13/722,632 However, contrary to Appellant’s arguments, as discussed above, the Examiner correctly finds that Berger’s disclosure of a multilayer cap structure 230 coupled to a granular layer 210 (recording structure) of a magnetic recording medium, and disclosure of the suitability of forming magnetic layers 232, 236 of the multilayer cap structure with a CoCrPtB alloy that includes 0.1—30 atomic % platinum and 0.1—20 atomic % boron, reasonably would have led one ordinary skill in the art to utilize such a CoCrPtB alloy as disclosed in Berger to form Kong’s single capping layer 169 that contacts first and second ferromagnetic layers 161, 163 of Kong’s recording layer 160 in Kong’s magnetic recording medium 100. Therefore, contrary to Appellant’s arguments, because the Examiner articulates reasoning having rational underpinning for combining the relied-upon disclosures of Kong and Berger, the proposed combination is not based on hindsight. In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (requiring “some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”) (cited with approval in KSR Int 7 Co. v. Teleflex /«c., 550 U.S. 398,418 (2007)). Appellant further argues that the boron and platinum ranges recited in claim 1 provide unexpected higher Hk combined with High Ms, allowing a very thin top continuous layer to be used to increase moment at the top of a perpendicular data recording medium. Br. 10 (citing Spec. 10). However, Appellant’s arguments lack persuasive merit because they are not supported by factual evidence, such comparative test data provided in a Declaration. Although Appellant points to page 10 of the Specification, we find no actual data supporting Appellant’s assertion of unexpected results in this portion of Appellant’s Specification. See, e.g., In re Geisler, 116 10 Appeal 2017-005526 Application 13/722,632 F.3d 1465, 1470 (Fed. Cir. 1997) (“[I]t is well settled that unexpected results must be established by factual evidence. ‘Mere argument or conclusory statements in the specification does not suffice.’”) (quoting In re De Blauwe, 736 F.2d 699, 705 (Fed.Cir. 1994)). Accordingly, a preponderance of the evidence relied-upon in this appeal supports the Examiner’s conclusion of obviousness, and we therefore sustain the Examiner’s rejection of claims 1, 2, 6—9, 18, and 19 under 35 U.S.C. § 103(a). Claim 5 Claim 5 depends from claim 1 and recites that the single-layer magnetic stabilization structure provides a magnetic saturation level of greater than about 600 eg/cm2 and anisotropic field strengths (Hk) of greater than about 15,000 Oersteds (Oe). The Examiner finds that “given that Kong in view of Berger discloses the exact material and concentration for the single-layer magnetic stabilization layer, it is clear that Kong in view of Berger inherently discloses the dependent claims[’] Hs and Hk values.” Ans. 9. Appellant argues that “Kong explicitly lowers Hs values” and Berger’s magnetic cap layers increase exchange coupling, while page 10 of Appellant’s Specification discloses that some boron and platinum combinations “can increase exchange coupling to the detriment of data storage performance.” Br. 12. Appellant argues that “the ordinary artisan would identify the contradiction between the cap structure of Berger intended on increasing exchange coupling with the claimed single magnetic stabilization structure that has increased Hk and Hs without increasing exchange coupling or jeopardizing data storage performance.” Id. 11 Appeal 2017-005526 Application 13/722,632 However, contrary to Appellant’s arguments, Appellant’s Specification states that the single-layer magnetic stabilization structure “operates to stabilize the top portion of the recording layers by providing a high level of exchange coupling to the top portion of the recording layers.” Spec. 5,11. 19-20. Thus, Appellant’s single-layer magnetic stabilization layer, like Berger’s multilayer cap structure, provides a high level of exchange coupling. In addition, as discussed above, because a combination of the relied- upon disclosures in Kong and Berger would have suggested a single capping layer having a composition and structure that appears to be the same as, or substantially similar to, the single-layer magnetic stabilization structure recited in claim 1, from which claim 5 depends, a reasonable basis exists for finding that the suggested single capping layer would possess the same characteristics or attributes as the recited single-layer magnetic stabilization structure, including a magnetic saturation level of greater than about 600 ep/cnf and anisotropic field strengths (Hk) of greater than about 15,000 Oersteds (Oe), as recited in claim 5. PAR Pharm., 773 F.3d at 1195; Spada, 911 F.2d at 709. Therefore, the burden shifts to Appellant to show otherwise. Best, 562 F.2d at 1255. Appellant does not direct us to any persuasive evidence or reasoning demonstrating that Kong’s single-layer capping layer formed of a CoCrPtB alloy that includes 0.1—30 atomic % platinum and 0.1—20 atomic % boron as disclosed in Berger would not have a magnetic saturation level and anisotropic field strengths as recited in claim 5. Br. 11-12. 12 Appeal 2017-005526 Application 13/722,632 Accordingly, a preponderance of the evidence relied-upon in this appeal supports the Examiner’s conclusion of obviousness, and we therefore sustain the Examiner’s rejection of claim 5 under 35 U.S.C. § 103(a). Rejections II and III We consider only claim 10, because claims 12—17 each depend directly or indirectly from claim 10. As set forth above, claim 10 requires the single layer of hard magnetic material to have a thickness of less than 1% of a topmost recording layer of the recording structure. Appellant’s Specification indicates that the recording structure recited in claim 10 may be comprised of a number of layers, including a soft magnetic underlayer 304 sputtered onto a substrate 302, one or more interlayers 306, and one or more recording layers 308. Spec. 5,11. 3—6, 24— 26; Fig. 3. Appellant’s Specification further discloses forming the single layer magnetic stabilization structure 310—or single layer of hard magnetic material as recited in claim 10—on the recording layer 308 of the recording structure. Spec. 5,11. 13—26; Fig. 3. Therefore, if the recording layer 308 includes more than one layer, the “topmost recording layer” of the recording structure recited in claim 10 is the layer of the recording layer 308 that is next to the single-layer magnetic stabilization structure 310 (single layer of hard magnetic material). If the recording layer 308 includes only one layer, the “topmost recording layer” of the recording structure recited in claim 10 is the single recording layer 308. The Examiner finds that Kong discloses that the capping layer 169 (single layer of hard magnetic material) of Kong’s recording layer 160 has a thickness of approximately 5 nm. Final Act. 6 (citing Kong | 65). The Examiner finds that “Kong fails to disclose that the magnetic stabilization 13 Appeal 2017-005526 Application 13/722,632 layer has a thickness that is less than 1 % of the thickness of the topmost one of the at least one magnetic recording layer.” Final Act. 6. The Examiner finds that Nishikawa discloses a magnetic recording layer having a thickness of 500 nm. Final Act. 6 (citing Nishikawa | 60). The Examiner concludes that it would have been obvious to one of ordinary skill in the art “to determine a thickness of the magnetic layer of Kong [] such that the magnetic stabilization layer was <1 % of the thickness thereof by optimizing the results effective variable (thickness of the granular layer) through routine experimentation.” Final Act. 6. However, as discussed above, Kong discloses a recording layer 160 having a three-layer structure comprised of a first ferromagnetic layer 161, a second ferromagnetic layer 163, and a capping layer 169 (single-layer magnetic stabilization structure). Kong | 61; Fig. 1. Kong discloses that the first and second ferromagnetic layers 161, 163 each have a thickness of approximately 10 nm, and the capping layer 169 has a thickness of approximately 5 nm. Kong | 65. The second (upper) ferromagnetic layer 163 of Kong’s recording layer 160 corresponds to the “topmost recording layer” recited in claim 10, in accordance with the description in Appellant’s Specification of Appellant’s multilayer recording structure (discussed above). Therefore, Kong discloses that the capping layer 169 (single layer of hard magnetic material) has a thickness that is 50% of the thickness of the second ferromagnetic layer 163 (topmost recording layer). The Examiner does not identify any disclosure in Kong imparting any significance to the thickness of the capping layer 169 (single-layer magnetic stabilization structure) relative to the thickness of the second ferromagnetic layer 163 (topmost recording layer). Nor does the Examiner identify any 14 Appeal 2017-005526 Application 13/722,632 disclosure in Kong indicating how decreasing the 5 nm thickness of Kong’s capping layer 169 (single-layer magnetic stabilization structure) relative to the 10 nm thickness of the second ferromagnetic layer 163 (topmost recording layer) by more than 50 times would impact Kong’s perpendicular magnetic recording medium. In re Sebek, 465 F.2d 904, 907 (CCPA 1972) (“Where, as here, the prior art disclosure suggests the outer limits of the range of suitable values, and that the optimum resides within that range, and where there are indications elsewhere that in fact the optimum should be sought within that range, the determination of optimum values outside that range may not be obvious.”) Accordingly, the Examiner does not identify any teaching in Kong, or provide any other persuasive reasoning or evidence, establishing that one of ordinary skill in the art would have had a reason to significantly decrease the thickness of Kong’s capping layer 169 (single-layer magnetic stabilization structure) such that it would be less than 1% of the thickness of the second ferromagnetic layer 163 (topmost recording layer), as recited in claim 10. Consequently, the Examiner’s evidence and explanation are insufficient to establish a prima facie case of obviousness of the subject matter of claim 10, and we therefore do not sustain the Examiner’s rejections of claims 10 and 12—17 under 35 U.S.C. § 103(a). DECISION We affirm the Examiner’s rejection of claims 1, 2, 5—9, 18, and 19 under 35 U.S.C. § 103(a) and reverse the Examiner’s rejections of claims 10 and 12—17 under 35 U.S.C. § 103(a). 15 Appeal 2017-005526 Application 13/722,632 No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
