SMITH, LILAN REN, 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, 4, 6–8, and 10.2,3 We have jurisdiction over this appeal under 35 U.S.C. § 6(b). We AFFIRM. 1 We use the word “Appellant” to refer to the “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies The Goodyear Tire & Rubber Company as the real party in interest. Appeal Brief filed July 24, 2018 (“Appeal Br.”) at 3. 2 Final Office Action entered July 6, 2018 (“Final Act.”) at 1. 3 Appellant cancelled claim 5 in an amendment filed July 10, 2018. Appeal 2019-004358 Application 15/163,075 2 CLAIMED SUBJECT MATTER Appellant claims a tire having an axis of rotation. Appeal Br. 3–4. Claim 1, the sole pending independent claim, is reproduced below, and illustrates the subject matter on appeal: 1. A tire having an axis of rotation, the tire comprising: two inextensible annular bead structures for attachment to a vehicle rim; a carcass-like structure having at least one reinforced ply, the carcass-like structure being wound about the two bead structures; a tread disposed radially outward of the carcass-like structure; and a shear band structure disposed radially between the carcass-like structure and the tread, each of the two bead structures including an apex constructed of a lightweight foam material, the lightweight foam material having cenospheres and carbon microspheres. Appeal Br. 11 (Claims Appendix) (emphasis added). REJECTIONS The Examiner maintains the following rejections in the Examiner’s Answer entered October 18, 2018 (“Ans.”):4 I.

Claims 8 and 10 under 35 U.S.C. § 103 as unpatentable over Zemla in view of Grah, Chen, Jalageri, and Paetz-Lauter.10 FACTUAL FINDINGS AND ANALYSIS Upon consideration of the evidence relied upon in this appeal and each of Appellant’s contentions, we affirm the Examiner’s rejections of claims 1, 4, 6–8, and 10 under 35 U.S.C. § 103, based on the findings of fact, conclusions of law, and response to Appellant’s arguments, well- expressed by the Examiner in the Final Action and the Answer. We add following for emphasis. We review appealed rejections for reversible error based on the arguments and evidence Appellant provides for each issue that Appellant identifies. 37 C.F.R. § 41.37(c)(1)(iv); Ex parte Frye, 94 USPQ2d 1072, 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 We first address the Examiner’s rejection of claims 1, 6, and 7 under 35 U.S.C. § 103 as unpatentable over Minagawa in view of Chen and Jalageri. Appellant presents arguments directed to independent claim 1 8 Zemla et al., US 2017/0361664 A1, published December 21, 2017. 9 Grah, US 2004/0187996 A1, published September 30, 2004. 10 Paetz-Lauter et al., US 9,174,363 B2, published November 3, 2015. Appeal 2019-004358 Application 15/163,075 4 only, to which we accordingly limit our discussion. Appeal Br. 4–6; 37 C.F.R. § 41.37(c)(1)(iv). Appellant argues that Minagawa, Chen, and Jalageri, when considered separately or in combination, do not disclose, and would not have suggested, a tire as recited in claim 1. Appeal Br. 4–5. Appellant argues that the Examiner does not provide a factual basis or rational underpinning to support the conclusion that it would have been obvious to modify Minagawa’s rubber foam composition to include carbon microspheres and carbon nanotubes as taught by Chen, and cenospheres as taught by Jalageri. Appeal Br. 5–6. Appellant asserts that the Examiner relies solely on hindsight judgment due to “significant factual deficiencies contained in the cited references.” Id. The Examiner provides reasoning having rational underpinning grounded in sound factual findings to support the Examiner’s conclusion of obviousness, contrary to Appellant’s arguments. In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006), cited with approval in KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 417–18 (2007) (explaining that there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness). Specifically, the Examiner finds that Minagawa discloses a tire comprising two inextensible annular bead parts (bead structures) for attachment to a vehicle rim, a carcass (carcass-like structure) wound about the two bead parts that includes at least one reinforced ply, a tread disposed radially outward of the carcass, and a belt layer (shear band structure) disposed radially between the carcass and the tread. Final Act. 4–5 (citing Minagawa Fig. 1); see also Minagawa ¶ 13. The Examiner finds that Appeal 2019-004358 Application 15/163,075 5 Minagawa discloses that the two bead parts include at least one apex constructed of a lightweight rubber foam material. Final Act. 5 (citing Minagawa ¶¶ 9, 17; Figs. 1, 2, and 3); see also Minagawa ¶¶ 6, 9, 11, 12, 13, 23. The Examiner finds that Minagawa “does not expressly disclose the composition of the rubber foam used in the bead apex.” Final Act. 5. The Examiner finds, however, that Chen teaches a wear-resistant rubber composite material widely used in tire rubbers that comprises carbon microspheres and carbon nanotubes, which together provide improved wear resistance and improved abrasion resistance relative to a conventional carbon black/rubber system. Final Act. 5 (citing Chen ¶ 4). The Examiner finds that Chen discloses that carbon microspheres and carbon nanotubes synergize to yield high-performance rubber composites having enhanced life, improved high and low temperature resistance, and improved high load resistance. Final Act. 5 (citing Chen ¶¶ 4, 5). In view of these disclosures in Chen, the Examiner concludes that it would have been obvious to one of ordinary skill in the art before the effective filing date of the present application to add carbon microspheres and carbon nanotubes as disclosed in Chen to the rubber foam disposed in the bead portion of Minagawa’s tire, to improve the wear resistance and abrasion resistance of the rubber foam, enhance the foam’s life, improve the foam’s high and low temperature resistance, and improve the foam’s high load resistance, as disclosed in Chen. Final Act. 5–6; Ans. 14. The Examiner finds that Jalageri discloses that cenospheres possess a unique combination of spherical shape, high compression, low specific gravity, good thermal and acoustical insulation properties, and inertness to Appeal 2019-004358 Application 15/163,075 6 acids and alkalis. Final Act. 6 (citing Jalageri p. 101). The Examiner finds that Jalageri discloses that carbon nanotubes have exceptionally high material properties, including strength, stiffness, and toughness, which are very close to the theoretical limits. Final Act. 6 (citing Jalageri p. 102). The Examiner finds that Jalageri discloses that including both cenospheres and carbon nanotubes in polymeric composites imparts the advantages of both materials to the composites, including enhanced flexural strength and modulus, increased tensile strength, enhanced modulus rupture and modulus of elasticity, and high tensile, bending, and impact strength. Final Act. 6 (citing Jalageri pp. 102, 104, 105). In view of these disclosures in Jalageri, the Examiner concludes that it would have been obvious to one of ordinary skill in the art to modify Minagawa’s rubber foam to include cenospheres as disclosed in Jalageri, in addition to carbon microspheres and carbon nanotubes as disclosed in Chen, to enhance the mechanical properties of the foam. Final Act. 6–7; Ans. 14– 15. The Examiner thus articulates a reasoned explanation grounded in thorough and sound factual findings for why one of ordinary skill in the art would have been led to combine the relied-upon disclosures of the applied prior art references to arrive at a tire as recited in claim 1. The Examiner’s rejection, therefore, is not based on improper hindsight reasoning as Appellant asserts. Appellant’s conclusory arguments fail to identify any specific error in the Examiner’s factual findings or rationale for the proposed combination of the applied prior art, and, in particular, do not direct us to any specific “factual deficiencies” in the applied prior art references. Appeal 2019-004358 Application 15/163,075 7 Appellant’s arguments are, therefore, unpersuasive of reversible error in the Examiner’s rejection. Appellant argues that “the current legal standard for obviousness is that the ‘combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.’” Appeal Br. 5–6 (citing KSR, 550 U.S. at 416; MPEP § 2141(I)). Appellant argues that the result of modifying Minagawa’s tire with the teachings of Chen and Jalageri as proposed by the Examiner would have been unpredictable and, therefore, nonobvious under KSR because “a tire is much more complex and unpredictable than” a combination of familiar elements according to known methods. Appeal Br. 5–6. Appellant’s conclusory assertion that modifying Minagawa’s tire in view of Chen and Jalageri as proposed by the Examiner would have been unpredictable does not identify any particular error in the Examiner’s factual findings or reasoning, or the Examiner’s rationale for the proposed combination. Nor does Appellant provide any objective evidence to show that one of ordinary skill in the art would not have had a reasonable expectation of successfully modifying the rubber foam in the bead portion of Minagawa’s tire in view of the relied-upon discloses of Chen and Jalageri as proposed by the Examiner. Appellant’s arguments, therefore, do not identify reversible error in the Examiner’s rejection. Even if modifying Minagawa’s tire with the teachings of Chen and Jalageri as proposed by the Examiner would have involved some degree of unpredictability as Appellant asserts, it is well-settled that, even in unpredictable arts, “[o]bviousness does not require absolute predictability of success . . . all that is required is a reasonable expectation of success.” In re Appeal 2019-004358 Application 15/163,075 8 Kubin, 561 F.3d 1351, 1360 (Fed. Cir. 2009) (emphasis omitted) (quoting In re O’Farrell, 853 F.2d 894, 903‒04 (Fed. Cir. 1988)). The Examiner provides a sound factual basis for finding that one of ordinary skill in the art reasonably would have expected that modifying the rubber foam disposed in the bead portion of Minagawa’s tire to include carbon microspheres and carbon nanotubes as disclosed in Chen, and to include cenospheres as disclosed in Jalageri, would improve numerous mechanical properties of Minagawa’s foam, as discussed above. Finally, although Appellant asserts that a combination of familiar elements according to known methods is “the current legal standard for obviousness,” the Supreme Court indicated in KSR that Graham v. John Deere Co. of Kansas City, 383 U.S. 1 (1966), sets out an objective analysis for applying § 103. KSR, 550 U.S. at 406. The Court explained: “Under § 103, the scope and content of the prior art are . . . determined; differences between the prior art and the claims at issue are . . . ascertained; and the level of ordinary skill in the pertinent art resolved. Against this background, the obviousness or nonobviousness of the subject matter is determined. Such secondary considerations as commercial success, long felt but unsolved needs, failure of others, etc., might be utilized to give light to the circumstances surrounding the origin of the subject matter sought to be patented.” While the sequence of these questions might be reordered in any particular case, the factors continue to define the inquiry that controls. Id. at 406–07 (internal citation omitted) (quoting Graham, 383 U.S. at 17– 18). In the context of discussing Supreme Court precedent on obviousness, the Court in KSR indicated that a combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results. Id. at 416 (citing United States v. Adams, 383 Appeal 2019-004358 Application 15/163,075 9 U.S. 39, 50–52 (1966)). This statement thus describes a particular circumstance in which a claimed invention is likely to be obvious, rather than providing “the current legal standard for obviousness” as Appellant asserts. We, accordingly, sustain the Examiner’s rejection of claims 1, 6, and 7 under 35 U.S.C. § 103 as unpatentable over Minagawa in view of Chen and Jalageri. Rejections II and III We turn now to the Examiner’s rejection of claims 1, 4, 6, and 7 under 35 U.S.C. § 103 as unpatentable over Zemla in view of Grah, Chen, and Jalageri (Rejection II), and the Examiner’s rejection of claims 8 and 10 under 35 U.S.C. § 103 as unpatentable over Zemla in view of Grah, Chen, Jalageri, and Paetz-Lauter (Rejection III). Appellant argues the claims subject to these rejections together on the basis of claim 1, to which we accordingly limit our discussion. Appeal Br. 6–9; 37 C.F.R. § 41.37(c)(1)(iv). Appellant argues that Zemla, Grah, Chen, and Jalageri, when considered separately or in combination, do not disclose, and would not have suggested, a tire as recited in claim 1. Appeal Br. 7–8. Appellant argues that the Examiner does not provide a factual basis or rational underpinning to support the conclusion that it would have been obvious to modify Zemla’s tire to include a shear band structure/belt structure between the tread and the carcass as disclosed in Grah, and to modify the foam material in the bead structure of Zemla’s tire to include carbon microspheres and carbon nanotubes as taught by Chen, and cenospheres as taught by Jalageri. Appeal Br. 7–9. Appellant asserts that the Examiner relies solely on hindsight Appeal 2019-004358 Application 15/163,075 10 judgment due to “significant factual deficiencies contained in the cited references.” Id. The Examiner provides reasoning having rational underpinning grounded in sound factual findings to support the Examiner’s conclusion of obviousness, contrary to Appellant’s arguments. Kahn, 441 F.3d at 988. Specifically, the Examiner finds that Zemla discloses a tire comprising two annular bead structures for attachment to a vehicle rim, at least one reinforcement element having at least one body ply (carcass-like structure having at least one reinforced ply) that includes a turnup end disposed around the bead structure (being wound about the two bead structures), and a tread portion disposed radially outward of the at least one reinforcement element (carcass-like structure). Final Act. 7–8 (citing Zemla ¶¶ 26, 43, 44; Figs. 1A, 1B, and 2); see also Zemla ¶¶ 41–46. The Examiner finds that Zemla discloses that each bead structure includes a cavity that may be partially or completely filled with a material configured to adjust the properties of the bead structure, such as a foam. Final Act. 8 (citing Zemla ¶¶ 33, 34; Figs. 1A and 1B). The Examiner finds that Zemla discloses that the cavity may also be at least partially filled with spheres that adjust the balance of the tire. Final Act. 8 (citing Zemla ¶ 35; Fig. 1B). The Examiner finds that Zemla does not disclose that the spheres may be cenospheres or carbon microspheres. Final Act. 8. The Examiner finds that Zemla also does not disclose a belt/ shear band structure disposed radially between the at least one reinforcement element and the tread portion of Zemla’s tire. Id. The Examiner finds, however, that Grah discloses a tire that supports its load solely through structural properties of the tire’s crown, sidewall, and Appeal 2019-004358 Application 15/163,075 11 bead portions, without support from internal air pressure. Final Act. 8–9 (citing Grah ¶¶ 5, 15). The Examiner finds that Grah’s tire includes elements similar to those of Zemla’s tire, but Grah’s tire further includes a reinforced annular band (shear band structure or belt structure). Final Act. 8 (citing Grah ¶¶ 24; Fig. 1). The Examiner finds that Grah discloses that the reinforced annular band is disposed radially inward of a tread portion and comprises an elastomeric shear layer. Final Act. 9 (citing Grah ¶ 25). The Examiner finds that Grah discloses that so forming a solid tire with a reinforced annular layer comprising a shear layer yields a solid tire that performs at levels expected from a conventional pneumatic tire. Final Act. 9 (citing Grah ¶¶ 4, 15). In view of these disclosures in Grah, the Examiner concludes that it would have been obvious to one of ordinary skill in the art to modify Zemla’s tire to include a shear band structure/belt structure between the tread and the carcass for reinforcing the crown portion of Zemla’s tire, to achieve the same level of performance expected of a conventional pneumatic tire, as taught by Grah. Final Act. 9; Ans. 19. The Examiner relies on the disclosures of Chen discussed above, and concludes that it would have been obvious to one of ordinary skill in the art to add carbon microspheres and carbon nanotubes as disclosed in Chen to the foam material disposed in the bead portion of Zemla’s tire to improve the wear resistance and abrasion resistance of the foam, enhance the foam’s life, improve the foam’s high and low temperature resistance, and improve the foam’s high load resistance. Final Act. 9–10. The Examiner also relies on the disclosures of Jalageri discussed above, and concludes that it would have been obvious to one of ordinary skill in the art to modify Zemla’s foam to Appeal 2019-004358 Application 15/163,075 12 include cenospheres as disclosed in Jalageri, in addition to carbon microspheres and carbon nanotubes as disclosed in Chen, to enhance the mechanical properties of the foam. Final Act. 10–11. The Examiner thus articulates a reasoned explanation grounded in thorough and sound factual findings for why one of ordinary skill in the art would have been led to combine the relied-upon disclosures of the applied prior art references to arrive at a tire as recited in claim 1. The Examiner’s rejection, therefore, is not based on improper hindsight reasoning as Appellant asserts. Appellant’s conclusory arguments fail to identify any specific error in the Examiner’s factual findings or rationale for the proposed combination of the applied prior art, and, in particular, do not identify any specific “factual deficiencies” in the prior art references. Appellant’s arguments are, therefore, unpersuasive of reversible error in the Examiner’s rejection. Appellant argues that “the current legal standard for obviousness is that the ‘combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.’” Appeal Br. 5–6 (citing KSR, 550 U.S. at 416; MPEP § 2141(I)). Appellant argues that the result of modifying Zemla’s tire with the teachings of Grah, Chen, and Jalageri as proposed by the Examiner would have been unpredictable and, therefore, nonobvious under KSR because “a tire is much more complex and unpredictable than” a combination of familiar elements according to known methods. Appeal Br. 7–9. Appellant’s conclusory assertion that modifying Zemla’s tire in view of Grah, Chen, and Jalageri as proposed by the Examiner would have been unpredictable does not identify any particular error in the Examiner’s factual Appeal 2019-004358 Application 15/163,075 13 findings or reasoning, or the Examiner’s rationale for the proposed combination. Nor does Appellant provide any objective evidence to show that one of ordinary skill in the art would not have had a reasonable expectation of successfully modifying Zemla’s tire to include a shear band structure/belt structure between the tread and the carcass as disclosed in Grah, and to include carbon microspheres and carbon nanotubes as disclosed in Chen, and cenospheres as disclosed in Jalageri, in the bead portion of the tire, as proposed by the Examiner. Appellant’s arguments, therefore, do not identify reversible error in the Examiner’s rejection. Similar to the situation discussed above for Rejection I, even if modifying Zemla’s tire with the teachings of Grah, Chen, and Jalageri as proposed by the Examiner would have involved some degree of unpredictability at the time of the effective filing date of the present application as Appellant asserts, it is well-settled that, even in unpredictable arts, “[o]bviousness does not require absolute predictability of success . . . all that is required is a reasonable expectation of success.” Kubin, 561 F.3d at 1360. The Examiner provides a sound factual basis for finding that one of ordinary skill in the art reasonably would have expected that modifying Zemla’s tire to include a shear band structure/belt structure between the tread and the carcass as disclosed in Grah would reinforce the crown portion of Zemla’s tire to enhance the tire’s performance, and modifying the rubber foam disposed in the bead portion of Zemla’s tire to include carbon microspheres and carbon nanotubes as disclosed in Chen, and to include cenospheres as disclosed in Jalageri, would improve numerous mechanical properties of Minagawa’s foam, as disclosed in Chen and Jalageri. Appeal 2019-004358 Application 15/163,075 14 We, accordingly, sustain the Examiner’s rejection of claims 1, 4, 6, and 7 under 35 U.S.C. § 103 as unpatentable over Zemla in view of Grah, Chen, and Jalageri, and the Examiner’s rejection of claims 8 and 10 under 35 U.S.C. § 103 as unpatentable over Zemla in view of Grah, Chen, Jalageri, and Paetz-Lauter.
