COLAIANNI, GEORGE C. BEST, and DEBRA L. DENNETT, Administrative Patent Judges. DENNETT, Administrative Patent Judge. DECISION ON APPEAL1 Pursuant to 35 U.S.C. § 134(a), Appellant2 appeals from the Examiner’s decision to reject claims 1–20 of Application 15/023,083. See Final Act. 1. We have jurisdiction under 35 U.S.C. § 6. 1 In our Decision, we refer to the Specification filed March 18, 2016 (“Spec.”) of Application 15/023,083 (“the ’083 Application”); the Final Office Action dated November 19, 2018 (“Final Act.”); the Appeal Brief filed April 15, 2019 (“Appeal Br.”); the Examiner’s Answer dated July 30, 2019 (“Ans.”); and the Reply Brief filed September 30, 2019 (“Reply Br.”). 2 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies SABIC Global Technologies B.V. as the real party in interest. Appeal Br. 2. Appeal 2020-000003 Application 15/023,083 2 For the reasons set forth below, we AFFIRM. BACKGROUND The ’083 Application relates to dark colored polycarbonate compositions that have reduced energy absorption when exposed to sunlight. Spec. ¶ 1. The ’083 Application describes that these dark colored polycarbonate compositions include an infrared reflective additive, which results in the composition absorbing less infrared energy. Id. The ’083 Application describes that the dark colored polycarbonate compositions are useful for forming exterior automotive parts, which can be exposed to prolonged periods of direct sunlight. Id. Claim 1 represents the ’083 Application’s claims and is reproduced below from the Claims Appendix of the Appeal Brief. 1. A polycarbonate composition for an exterior automotive layer, comprising: a polycarbonate polymer; an infrared reflective additive; a heat stabilizer; an anti-oxidant; and a UV-additive; a dye; wherein the polycarbonate composition has an L-value of 20 or below when measured in the CIELAB color space under DREOLL conditions, and has an Energy Absorption (AE) of less than 90% when measured according to ISO 9050. Appeal Br. 17 (Claims App.) (emphasis added). Appeal 2020-000003 Application 15/023,083 3 REFERENCES The Examiner relies on the following prior art in rejecting the claims on appeal: Name Reference Date Loucka et al.

(“Momose”) US 7,727,418 B2 June 1, 2010 Peter et al. (“Peter”)3 CN 1882656 B Jan. 26, 2011 REJECTIONS The Examiner maintains the following rejections4: 1. Claims 1, 2, 4–14, 19, and 20 under 35 U.S.C. § 103 as unpatentable over Faber, in view of Walker, and further in view of Loucka. Final Act. 3. 2. Claim 3 under 35 U.S.C. § 103 as unpatentable over Faber, in view of Walker and Loucka, and further in view of Momose. Final Act. 7. 3. Claims 15–18 under 35 U.S.C. § 103 as unpatentable over Faber, in view of Walker, Loucka, and further in view of Peter. Final Act. 8. 3 The Examiner relies on a machine translation of Peter, to which Appellant does not object. See Appeal Br. 14–15. 4 Because this application claims priority to an application filed after the March 16, 2013 effective date of the America Invents Act, we refer to the AIA version of the statutes. Appeal 2020-000003 Application 15/023,083 4 DISCUSSION Ground 1: Rejection of claims 1, 2, 4–14, 19, and 20 as obvious over Faber, Walker, and Loucka The Examiner rejects claims 1, 2, 4–14, 19, and 20 as unpatentable under 35 U.S.C. § 103 over Faber, in view of Walker, and further in view of Loucka. Final Act. 3. Appellant argues claims 1, 2, 7, 9, and 11–14 as a group, and argues claims 4–6, 8, 10, 19, and 20 separately. Appeal Br. 5–13. We select claim 1 as representative of the group. Claims 2, 7, 9, and 11–14 will stand or fall with claim 1. 37 C.F.R. § 41.37(c)(1)(iv). We discuss claims 4–6, 8, 10, 19, and 20 separately. Claim 1 The Examiner finds that Faber teaches each component of the claimed polycarbonate composition, except that Faber does not teach: (i) that the infrared reflective additive is a complex inorganic colored pigment (CICP) comprising a mixed metal oxide, or (ii) the amount of the infrared reflective additive. Final Act. 3–4. The Examiner finds Walker teaches that the infrared reflective pigment can be a CICP, which is present in amounts of no more than about 5 wt% in the plastic composition. Id. at 4 (citing Walker ¶ 37). The Examiner determines that it would have been obvious to one of ordinary skill in the art to use Walker’s CICP as the infrared reflective additive in amounts of no more than 5 wt% in Faber’s composition “to produce a desired color in the visible range and reflect a significant portion of the IR radiation outside of the visible range, to keep objects cooler under solar ra[dia]tion[,] and to exhibit much less heat build-up and much higher infrared radiation reflectance” as taught by Walker. Final Act. 5. Appeal 2020-000003 Application 15/023,083 5 The Examiner finds that the proposed modification of Faber’s composition with Walker’s teachings would not have resulted in a CICP comprising a mixed metal oxide such as chromium iron oxide or CICP Brown 29. Final Act. 5. However, the Examiner finds that Loucka teaches a brown CICP pigment comprising chromium oxide and iron oxide and that the pigment includes CICP Brown 29. Id. (citing Loucka Abstract; col. 1, ll. 64–67; col. 2, ll. 21–24 and 30–33). The Examiner determines that it would have been obvious to one of ordinary skill in the art to use Loucka’s brown CICP pigment comprising chromium oxide and iron oxide as the CICP pigment in Faber’s composition, as modified by Walker, to provide CICP pigment with high pigment strength, good weathering characteristics, high tinting strength, high temperature resistance, small particle size, stab[ility] during handling, stab[ility] to oxidation and high[] dispersibility[,] as well as to provide strong and bright brown color[,] while not degrading the integrating and uniformity of the film. Final Act. 6–7. With respect to the claimed L-value and AE properties, the Examiner reasons that because Faber’s composition, as modified by Walker and Loucka, “is identical to that presently claimed,” Faber’s modified composition would have exhibited the presently claimed property. Id. at 7. Appellant argues that Faber’s concern with transparent compositions having a low haze establishes a teaching away from the claimed dark compositions having L-values of 20 or below. Appeal Br. 6. Appellant’s argument lacks persuasive merit. Teaching away requires that a reference “criticize, discredit, or otherwise discourage the solution claimed” by Appellant. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Faber, however, discloses the use of infrared reflective additive along with colorants, such as carbon blacks and Pigment Brown 24, in amounts of 0.01 Appeal 2020-000003 Application 15/023,083 6 to 10 wt%, which would have resulted in a composition that is dark and transparent. See Ans. 10 (citing Faber ¶ 67)). We agree with the Examiner that Faber does not teach away from dark compositions. Ans. 10. Appellant contends that one of skill in the art would not have added Walker’s infrared reflective CICP colorant to the transparent polycarbonate composition of Faber because “Walker exemplifies that their compositions comprising their reflective CICP colorant were ‘nominally black in color,’” i.e., not transparent. Appeal Br. 7–8 (citing Walker ¶ 53). But Appellant relies not on Walker’s full disclosure, rather on only one of two examples; Walker’s other example discloses that the compositions were “nominally gray in color.” Walker ¶ 57. “A reference must be considered for everything that it teaches, not simply the described invention or a preferred embodiment.” In re Applied Materials, Inc., 692 F.3d 1289, 1298 (Fed. Cir. 2012). Consideration of the entirety of Walker demonstrates that the reference is not limited to a disclosure of a black, non-transparent composition. Appellant’s argument is not supported by the record. Appellant argues that there is no motivation to modify Faber with Loucka’s colorant because such modification “would similarly change the principle operation of Faber.” Appeal Br. 8. No further explanation of how Faber’s principle of operation would be altered is provided. We find the argument unpersuasive. Appellant points out that claim 1 of the ’083 Application recites a polycarbonate composition with a L-value of 20 or below, stating that “such an L-value indicated a black colored composition.” Appeal Br. 8. Appellant then contends that Loucka teaches away from black colored compositions because Loucka’s inventive examples possess higher L-values of 60. Id. (citing Loucka col. 9, ll. 22–32, Table 1). The argument is not persuasive Appeal 2020-000003 Application 15/023,083 7 for at least three reasons. First, as mentioned above, teaching away requires that a reference “criticize, discredit, or otherwise discourage the solution claimed” by Appellant. See Fulton, 391 F.3d at 1201. We find no such criticism, discrediting, or discouragement in Loucka. Second, contrary to Appellant’s suggestion, the ’083 Application states that “the present polycarbonate composition has a dark color,” not a black color. Appeal Br. 5–6 (citing Spec. ¶¶ 54, 94) (emphasis added). Thus, Appellant’s position is unsupported by the Specification. Finally, as discussed in relation to Walker above, Loucka’s disclosure is not limited to its examples, but must be considered for all that it teaches. There is no teaching away to be found here. Appellant contends that the claimed L-value and energy absorption are not inherent in the composition of Faber or in the combination of references cited. Appeal Br. 6, 8–9. However, “[f]or chemical compounds, the structure of the compound and its properties are inseparable considerations in the obviousness determination.” Sanofi-Synthelabo v. Apotex, Inc., 550 F.3d 1075, 1086 (Fed. Cir. 2008); see also In re Papesch, 315 F.2d 381, 391 (CCPA 1963) (“From the standpoint of patent law, a compound and all of its properties are inseparable; they are one and the same thing.”). 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 Best, 562 F.2d 1252, 1255 (Fed. Cir. 1977) (“Whether the rejection is based on ‘inherency’ under 35 U.S.C. § 102, [or] on ‘prima facie obviousness’ under 35 U.S.C. § 103, . . . the burden of proof Appeal 2020-000003 Application 15/023,083 8 is the same.”). Appellant merely states that “the artisan would not have expected the presently claimed ‘dark’ composition having an L-value of 20 or below to be capable of achieving the claimed Energy Absorption (AE) of less than 90% as this feature is difficult to achieve.” Appeal Br. 9. Appellant’s comparison of its invention to commercially available materials in Table 2 of the Specification (rather than to the prior art cited) fails to meet the burden of proof. This argument is unpersuasive. Appellant’s unexpected results argument is also unavailing. See Appeal Br. 7, 12. Appellant contends that evidence that the composition possess superior and unexpected properties in one of a spectrum of common properties can be sufficient to rebut a prima facie case of obviousness. Id. at 12. “[T]he burden of showing unexpected results rests on he who asserts them.” In re Klosak, 455 F.2d 1077, 1080 (CCPA 1972). “It is well settled ‘that objective evidence or non-obviousness must be commensurate in scope with the claims which the evidence is offered to support.’” In re Grasselli, 713 F.2d 731, 743 (Fed. Cir. 1983) (quoting In re Tiffin, 448 F.2d 791 (CCPA 1971)). Claim 1 encompasses polycarbonate compositions much broader in scope than the single inventive composition in the Specification whose energy absorption is disclosed, thus the evidence offered is not commensurate in scope with claim 1. Compare Appeal Br. 17 (Claims App.), with Spec. ¶ 105 (Table 2). In addition, when used as evidence of nonobviousness, the results must be shown to be unexpected compared to the closest prior art. In re Baxter Travenol Labs., 952 F.2d 388, 392 (Fed. Cir. 1991). Instead, Appellant only compares a single composition to “commercially available materials.” See Spec. ¶ 105 (Table 2). Appellant fails to meet its burden of showing unexpected results. Appeal 2020-000003 Application 15/023,083 9 We sustain the rejection of claim 1, and, for the same reasons, the rejection of claims 2, 7, 9, and 11–14 over Faber, Walker, and Loucka. Claims 4–6 and 20 Appellant argues that Walker and Loucka fail to teach that a composition comprising Walker’s complex or Loucka’s brown iron- chromium pigment having an L-value of about 57 or more would have resulted in a composition having an L-value of 20 or below and an AE of less than 90% (Appeal Br. 11). We are not persuaded by these arguments because each improperly attacks the references individually instead of addressing what the combined teachings of the applied prior art would have suggested. See In re Keller, 642 F.2d 413, 426 (CCPA 1981). As set forth above, because the combined teachings of Faber, Loucka, and Walker render obvious the claimed compound, the combined teachings also render obvious the properties of the claimed compound. See Papesch, 315 F.2d at 391. We sustain the rejection of claims 4–6 and 20 over Faber, Walker, and Loucka. Claim 10 Appellant contends that Faber fails to provide any motivation for one of skill in the art to specifically select the claimed components from “a laundry list of potential thermal stabilizers . . . and a laundry list of potential UV absorbing additives.” Appeal Br. 11 (citing Faber ¶¶ 57, 60). That a reference “discloses a multitude of effective combinations does not render any particular formulation less obvious. This is especially true because the claimed composition is used for the identical purpose taught by the prior art.” Merck & Co. v. Biocraft Labs., Inc., 874 F.2d 804, 807 (Fed. Appeal 2020-000003 Application 15/023,083 10 Cir. 1989)); see also In re Corkill, 771 F.2d 1496, 1500 (Fed. Cir. 1985) (obviousness rejection of claims affirmed in light of prior art teaching that “hydrated zeolites will work” in detergent formulations, even though “the inventors selected the zeolites of the claims from among ‘thousands’ of compounds”); In re Susi, 440 F.2d 442, 445 (CCPA 1971) (obviousness rejection affirmed where the disclosure of the prior art was “huge, but it undeniably include[d] at least some of the compounds recited in appellant’s generic claims and [was] of a class of chemicals to be used for the same purpose as appellant’s additives”). In this case, Faber discloses thermal stabilizers and UV absorbing additives that are presently claimed. Faber ¶¶ 57, 60. Each of the claimed components are disclosed or suggested in Faber as useful for forming the polycarbonate composition. Id. We sustain the rejection of claim 10 over Faber, Walker, and Loucka. Claims 8 and 19 Appellant argues that claims 8 and 19 further limit the amounts of the respective components of the infrared reflective additive and the dye, but Faber “discloses extremely broad ranges of amounts that these components could be without offering any indication that the components in these specific amounts could result in a composition having an L-value of 20 or below and an Energy Absorption (AE) of less than 90%.” Appeal Br. 11– 12. Appellant’s argument lacks persuasive merit by attacking Faber individually when the rejection is based on the combined teachings of Faber, Walker, and Loucka. See Keller, 642 F.2d at 426. The Examiner relies upon Walker for teaching the claimed amount of infrared reflective additive. The Examiner finds that Faber teaches an amount of dye, which overlaps the Appeal 2020-000003 Application 15/023,083 11 claimed range. Final Act. 4. See In re Peterson, 315 F.3d 1325, 1329 (Fed. Cir. 2003) (“A prima facie case of obviousness typically exists when the ranges of a claimed composition overlap the ranges disclosed in the prior art.”). Appellant fails to overcome the obviousness rejection. See Ans. 17– 18, 25–27. As set forth above, because the combined teachings of Faber, Loucka, and Walker render obvious the claimed compound, the combined teachings also render obvious the properties of the claimed compound. See Papesch, 315 F.2d at 391. We sustain the rejection of claims 8 and 19 over Faber, Walker, and Loucka. Ground 2: Rejection of claim 3 as obvious over Faber, Walker, Loucka, and Momose Claim 3 depends from claim 1, and recites “wherein the dye comprises Solvent Green 3 and Solvent Red 135.” Appeal Br. 17 (Claims App.). The Examiner rejects claim 3 as unpatentable under 35 U.S.C. § 103 over Faber in view of Walker and Loucka, and further in view of Momose, on which the Examiner relies for teaching a dye comprising Solvent Green 3 and Solvent Red 135. Final Act. 7. Appellant repeats its argument that Faber teaches away from dark composition having L-values of less than or equal to 20. Appeal Br. 14. However, as set forth above, Faber’s modified composition would have resulted in a composition that is dark and transparent, thus Faber does not teach away. Appellant also argues that one of skill in the art would not have modified Faber, which is directed to polycarbonate compositions having a high transmission of visible light, by incorporating Momose’s dye because it Appeal 2020-000003 Application 15/023,083 12 would have rendered Faber’s composition obsolete for its intended purpose. Appeal Br. 14. We understand Appellant’s argument to be that incorporating Momose into Faber would result in a composition having “less than or equal to 15% transmission of visible light.” See id. at 8 (citing Momose 1:55–60). But “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference.” Keller, 642 F.2d at 425. “Combining the teachings of references does not involve an ability to combine their specific structures.” In re Nievelt, 482 F.2d 965, 968 (CCPA 1973). Use of the two dyes as disclosed by Momose in Faber involves the simple substitution of one known element for another, and does not lead to nonobviousness. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 416 (2007). We sustain the rejection of claim 3 as obvious over Faber, Walker, Loucka, and Momose. Ground 3: Rejection of claims 15–18 as obvious over Faber, Walker, Loucka, and Peter The Examiner rejects claims 15–18 as unpatentable under 35 U.S.C. § 103 over Faber in view of Walker and Loucka, and further in view of Peter. Final Act. 8. Appellant argues that these claims are patentable because Peter fails to cure the deficiencies of Faber, Walker, and Loucka. Appeal Br. 14. Having found no deficiencies in Faber, Walker, and Loucka, we sustain the rejection of claims 15–18 as obvious over Faber, Walker, Loucka, and Peter.
