TIMM, JEFFREY T. SMITH, and CHRISTOPHER C. KENNEDY, Administrative Patent Judges. SMITH, Administrative Patent Judge. DECISION ON APPEAL Pursuant to 35 U.S.C. § 134(a), Appellant1 appeals from the Examiner’s decision to reject claims 1–6, 9, and 11–21. We have jurisdiction under 35 U.S.C. § 6(b). We REVERSE. 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 SABIC GLOBAL TECHNOLOGIES B.V. Appeal Br. 2. Appeal 2019-006329 Application 15/111,234 2 STATEMENT OF THE CASE The appealed invention is directed to a multilayer sheet, wherein the substrate comprises a hard coating on a first surface (cap layer) and flexible coating on the second surface (core layer). Claim 2 illustrates the subject matter on appeal and is reproduced below: 2. A multilayer sheet, comprising: a substrate comprising a cap layer comprising a polymeric material; and a core layer, wherein when joined, the cap layer forms a first surface of the substrate and the core layer forms a second surface of the substrate; a first coating layer disposed on the first surface of the substrate, wherein the first coating is a hard coating with a Taber Abrasion as measured according to ASTM D1044-05 of less than or equal to 5%; and a second coating layer disposed on the second surface of the substrate, wherein the second coating is a flexible coating with a Taber Abrasion as measured according to ASTM D1044- 05 of greater than or equal to 7%; wherein the multilayer sheet passes a ball drop test from a distance of greater than or equal to 50 centimeters. Appeal Br. 13, Claims Appendix. The following rejections are presented for appeal:2,3 Claims 1–3, 5, 6, 9, 11, 13–16, 20, and 21 under 35 U.S.C. § 103(a) as unpatentable over Gilmer (US 2006/0286383 A1, published Dec. 21, 2006). Claims 4, 12, and 17–19 under 35 U.S.C. § 103 as unpatentable over Gilmer in view of Sharygin (US 2010/0003523 A1, published Jan. 7, 2010). 2 The complete statement of the rejection on appeal appears in the Examiner’s Answer. (Ans. 3–6.) 3 The 35 U.S.C. § 112, first paragraph, rejection of claims 22 and 23 has been withdrawn since the claims have been cancelled. (Ans. 7.) Appeal 2019-006329 Application 15/111,234 3 OPINION After review of the respective positions provided by Appellant and the Examiner, we REVERSE the Examiner’s rejections under 35 U.S.C. § 103(a). The dispositive issue on appeal is: Did the Examiner err in determining that Gilmer describes or suggests a multilayer sheet comprising a hard coating on a first surface and a flexible coating on the second surface of the substrate, wherein the first coating layer has a Taber Abrasion as measured according to ASTM D1044-05 of less than or equal to 5% and the second coating layer has a Taber Abrasion as measured according to ASTM D1044-05 of greater than or equal to 7% as required by independent claim 2?4 The Examiner finds Gilmer teaches a shaped article that may have more than one layer prepared from a thermoplastic resin and resulting in the structure required by independent claim 2. (Ans. 3; Gilmer ¶ 15.) The Examiner recognizes that Gilmer does not disclose that the different surfaces of the article may be coated with two different coating compositions. (Ans. 3.) However, the Examiner determines it would have been obvious to utilize one coating composition comprising a hexafunctional urethane acrylate and another coating comprising a difunctional urethane acrylate because Gilmer discloses that the coating composition may contain urethane diacrylate or urethane hexa-acrylate. (Ans. 3–4; Gilmer ¶¶ 31, 32.) The Examiner also finds that Gilmer Examples 1 and 6 utilize different compositions that result 4 We limit our discussion to claim 2, the only independent claim on appeal. Appeal 2019-006329 Application 15/111,234 4 in a Taber Abrasion according to ATSM D1044 after 100 cycles of 1.26%5 and 9.75% respectively. (Ans. 4; Gilmer Tables 2 and 6.) The Examiner concludes it would have been obvious to one of ordinary skill in the art to have used two different coating layers on the two surfaces of the article in Gilmer for the purpose of obtaining one surface with increased flexibility and the opposite surface having increased hardness. (Ans. 4.) In rejecting claims under 35 U.S.C. § 103, it is incumbent upon the Examiner to establish a factual basis to support the legal conclusion of obviousness. See In re Fine, 837 F.2d 1071, 1073 (Fed. Cir. 1988). In so doing, the Examiner must make the factual determinations set forth in Graham v. John Deere Co., 383 U.S. 1, 17 (1966) (noting that 35 U.S.C. § 103 leads to three basic factual inquiries: (1) the scope and content of the prior art; (2) the differences between the prior art and the claims at issue; and (3) the level of ordinary skill in the art). Furthermore, the Examiner’s obviousness rejection must be based on “some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness” . . . . [H]owever, the 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. KSR Int’l Co. v. Teleflex, Inc., 550 U.S. 398, 418 (2007) (quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). If the Examiner’s burden is met, the burden then shifts to the Appellant to overcome the prima facie case with argument and/or evidence. Obviousness is then determined on the basis of the evidence as a whole and 5 The Examiner improperly states this value as 1.29%. (Compare Ans. 4, with Gilmer Table 2.) Appeal 2019-006329 Application 15/111,234 5 the relative persuasiveness of the arguments. See In re Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992). Although Gilmer discloses a shaped article that may contain more than one coating, the Examiner does not adequately rebut Appellant’s assertions in the Brief that Gilmer fails to disclose or suggest: (1) a multilayer sheet comprising a hard coating on a first top surface and a flexible coating on the second bottom surface as required by independent claim 2; (2) the first coating is a hard coating having a Taber Abrasion of less than or equal to 5% and the second coating is a flexible coating having a Taber Abrasion of greater than or equal to 7% as required by independent claim 2; and (3) a basis to pick and choose from the many urethane acrylates to obtain 2 different coatings having the abrasion resistance requirements of independent claim 2. (Appeal Br. 4–7.) As Appellant points out and the record supports, Gilmer fails to provide sufficient guidance to a person of ordinary skill in the art to form a multilayer article wherein the first layer on the first surface is a hard coating and the second layer on the second surface is a flexible coating as required by independent claim 2. To the extent Gilmer discloses the at least one urethane acrylate may be difunctional or hexafunctional, the Examiner has failed to identify a disclosure that suggests the selection of both a first coating on the first side of the substrate having a difunctional urethane acrylate and a second coating on the second side of the substrate that is a hexafunctional urethane acrylate. Thus, the Examiner has not provided an adequate technical explanation with the requisite rational underpinning of why or how one skilled in the art, absent impermissible hindsight, would Appeal 2019-006329 Application 15/111,234 6 have arrived at the claimed multilayer sheet having both surfaces with the Taber Abrasion as required by independent claim 2. Since we reverse because the Examiner has not established that the relied-upon disclosures are sufficient to support obviousness, we need not reach the issue of the sufficiency of the evidence of unexpected results presented in the Specification argued by Appellant. Cf. In re Geiger, 815 F.2d 686, 688 (Fed. Cir. 1987). The Examiner rejected claims 4, 12, and 17–19 as obvious over Gilmer in combination with Sharygin. We did not sustain the Examiner’s rejection of independent claim 2 for the reasons presented by Appellant and given above. We, likewise, do not sustain the Examiner’s decision to reject dependent claims 4, 12, and 17–19, since this rejection is premised on the Examiner’s misinterpretation of Gilmer. We need not reach whether the Examiner’s reliance on Sharygin in addition to Gilmer for the rejection of the dependent claims is supported by the evidence of record. The Examiner cited Sharygin to address limitations different from independent claim 2. For these reasons, we reverse the Examiner’s 35 U.S.C. § 103 rejections of claims 1–6, 9, and 11–21.
