BEST, CHRISTOPHER C. KENNEDY, and BRIAND. RANGE, Administrative Patent Judges. KENNEDY, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134(a) from the Examiner's decision rejecting claims 1-7, 10, 11, and 18-22. We have jurisdiction under 35 U.S.C. § 6(b ). We AFFIRM. BACKGROUND The subject matter on appeal relates to curable coating compositions. E.g., Spec. ,r 2; Claim 1. Claim 1 is reproduced below from page 44 (Claims Appendix) of the Appeal Brief: 1 The Appellant is the Applicant, The Sherwin-Williams Company, which is also identified as the real party in interest. See Br. 4. Appeal2017-008910 Application 14/710,680 1. A coating composition comprising: a polymeric binder, which is the reaction product of: (a) an acetoacetoxy functional polyester epoxy block or graft copolymer; and (b) a crosslinking component, wherein the crosslinking component is an isocyanate functional crosslinker. REJECTIONS ON APPEAL The claims stand rejected under 35 U.S.C. § 103 as follows: 1. Claims 1-7, 10, and 18-20 over DePompei (US 5,714,563, issued Feb. 3, 1998) and Kordomenos (US 4,698,398, issued Oct. 6, 1987); 2. Claim 11 over DePompei, Kordomenos, and Sawaguchi (JP 2003- 231861, dated Feb. 13, 2002); 3. Claim 21 over DePompei, Kordomenos, and Ohrbom (US 2004/0068060 Al, published Apr. 8, 2004); 4. Claims 21 and 22 over DePompei, Kordomenos, and Mosser (US 5,116,672, issued May 26, 1992). ANALYSIS After review of the cited evidence in the appeal record and the opposing positions of the Appellant and the Examiner, we determine that the Appellant has not identified reversible error in the Examiner's rejections. Accordingly, we affirm the rejections for reasons set forth below, in the Final Action, and in the Examiner's Answer. See generally Final Act. 2-21; Ans. 2-23. 2 Appeal2017-008910 Application 14/710,680 Rejection 1 The Examiner finds that DePompei teaches a curable composition comprising a polymeric binder that is the reaction product of (a) an acetoacetoxy functional polyester and (b) an isocyanate functional crosslinker. Ans. 2. The Examiner finds that DePompei teaches that the acetoacetoxy functional polyester is prepared by acetoacetylation of a polyhydroxy polyester, but does not teach the claimed epoxy polyester block or graft copolymer. Id. The Examiner finds that Kordomenos teaches similar coating compositions that have "a polyester epoxy graft or block copolymer formed by reacting a diepoxide with a hydroxyl functional acid (e.g., dimethylolpropionic acid), with polymerization of lactones." Id. (citations omitted). The Examiner further finds that Kordomenos "teaches that the polyester epoxy graft of block copolymer used therein has a number of benefits, including flexibility and toughness, and corrosion resistance." Id. ( citation omitted). The Examiner determines that it would have been obvious "to modify the composition of DePompei, using the polyester epoxy block or graft copolymer having hydroxyl functionality taught by Kordomenos as the base polyester polyol for the acetoacetoxy functional polyester, so as to obtain the benefits of flexibility and toughness, and corrosion resistance as taught by Kordomenos, thereby arriving at the invention of claim 1." Id. at 3. The Appellant repeatedly argues that the composition of the combined prior art "differ[ s] dramatically from the claimed compositions." E.g., Br. 17, 19, 20, 21, 22, 24, 25, 26, 27, 31. For support, the Appellant relies principally on the following assertions: (1) DePompei's compositions cure 3 Appeal2017-008910 Application 14/710,680 rapidly without heating, (2) DePompei's reactants must be kept in anhydrous conditions before use, (3) Kordomenos's compositions cure rapidly when heated, ( 4) the claimed compositions cure under ambient conditions over extended periods, and ( 5) the reactants used to create the claimed compositions do not require anhydrous storage conditions. See id. at 13-1 7. Relying on those assertions, the Appellant concludes: Therefore, a skilled artisan that combined the cited references could not have obtained the invention of claim 1. The compositions resulting from a combination of the references would have to result from reactants that had to be stored under anhydrous conditions and would result in compositions that rapidly cure in minutes when heated to elevated temperatures, e.g., temperatures of about five (5) times ambient temperatures. The present claimed compositions, in contrast, do not require reactants stored under anhydrous conditions and result in compositions that cure under ambient conditions over extended periods, e.g,, days (See Example 3 and Example 4 where ambient cure time is seven (7) days). Given these dramatic differences, it is clear that a skilled artisan that combined the references could hot [sic] have obtained the invention of claim 1 as asserted by the Examiner. E.g., Br. 17. Those arguments are not persuasive. As the Examiner explains, the Appellant identifies alleged differences between the prior art and the Appellant's disclosure (e.g., anhydrous storage conditions, cure times) that do not appear in the claims. E.g., Ans. 14; see also In re Hiniker Co., 150 F.3d 1362, 1369 (Fed. Cir. 1998) ("The invention disclosed in Hiniker's written description may be outstanding in its field, but the name of the game is the claim."); In re Van Geuns, 988 F.2d 1181, 1184 (Fed. Cir. 1993) (rejecting appellant's nonobviousness argument as based on limitation not recited in claim). Although the Appellant asserts that "these conditions 4 Appeal2017-008910 Application 14/710,680 regarding reactant storage and cure process do not need to be read into the present claims," Br. 18, the Appellant does not persuasively dispute the Examiner's finding that the proposed combination of DePompei and Kordomenos would result in a polymeric binder that is the reaction product of recited elements (a) and (b). That appears to be all that is required to fall within the scope of claim 1. The Appellant points to nothing in the claim language that would exclude the use of, e.g., (1) reactants that must be stored under anhydrous conditions, or (2) reactants that cure rapidly under heat. Nor does the Appellant identify any disclosure in the Specification or the prior art references that suggests that the use of such reactants falls beyond the scope of claim 1. See id. at 13-28. Even assuming that the Appellant accurately asserts that the composition of the combined prior art has certain "dramatic" differences relative to the claimed composition, that would not necessarily cause the composition of the combined prior art to fall beyond the scope of claim 1. For example, a claim directed to "an apparatus comprising an engine" would cover both an airplane and a motorboat, notwithstanding the fact that an airplane and a motorboat might be described as significantly different from each other. In this case, the Appellant has not adequately explained how the alleged differences between the prior art and the disclosure of the Specification relate to the limitations actually recited in claim 1. See Hiniker, 150 F.3d at 1369; Van Geuns, 988 F.2d at 1184. The Appellant also argues that "[ a ]dding the Kordomenos reactants to DePompei and creating a composition would require heating the Kordomenos reactants to at least 120°C. Such heating would be 5 Appeal2017-008910 Application 14/710,680 incompatible with the ambient cure conditions taught in DePompei and would create a composition that is unsatisfactory and unusable." Br. 18. That argument is not persuasive because it is attorney argument unsupported by evidence or cogent reasoning. See, e.g., In re Huang, 100 F.3d 135, 139-40 (Fed. Cir. 1996); In re Pearson, 494 F.2d 1399, 1405 ( CCP A 197 4) ("Attorney's arguments in a brief cannot take the place of evidence."). DePompei and Kordomenos both describe coating compositions that include similar ingredients, including polymeric compounds and polyisocyanate crosslinking agents. E.g., DePompei at Abstract, 5:25-27; Kordomenos at Abstract. The Appellant identifies no persuasive reason that a person of ordinary skill would have believed that the combination of DePompei and Kordomenos, as proposed by the Examiner, would result in an unusable composition. Nor does the Appellant allege that a person of ordinary skill in the art would not have been able to determine a suitable cure temperature for the composition of DePompei and Kordomenos. Additionally, in the Answer, the Examiner finds that Kordomenos does not require curing temperatures of 120°C, but instead teaches "curing temperatures of 120 degrees Corless." Ans. 18. The Appellant does not file a Reply Brief to contest that finding. On this record, we are not persuaded that alleged differences in cure temperature would have dissuaded a person of ordinary skill in the art from combining DePompei and Kordomenos. The Appellant further argues that "[ t ]he Examiner provided no reasoning that would have motivated a skilled artisan to combine the references to achieve the present invention." E.g., Br. 19. That argument is not persuasive because it ignores the Examiner's finding that a person of 6 Appeal2017-008910 Application 14/710,680 ordinary skill would have combined the references "to obtain the benefits of flexibility and toughness, and corrosion resistance as taught by Kordomenos." Ans. 3. The Appellant also argues that DePompei "teaches away from the present invention" because it teaches anhydrous storage conditions and rapid curing. Br. 28. The Appellant argues that Kordomenos "teaches away from the present invention" because it discloses heated curing. Id. However, as set forth above, the Appellant has not persuasively explained how reactants that use anhydrous storage conditions, or rapid/heated curing, are excluded by claim 1. Accordingly, even assuming the Appellant's description of the prior art is accurate, those features cannot provide the basis for teaching away from the claimed invention. We have carefully considered the Appellant's arguments concerning claim 1, and we are not persuaded that the Appellant has identified reversible error in the rejection. See In re Jung, 637 F.3d 1356, 1365 (Fed. Cir. 2011) ("[I]t has long been the Board's practice to require an applicant to identify the alleged error in the examiner's rejections .... "). Accordingly, we affirm the Examiner's rejection of claim 1. The Appellant does not meaningfully dispute the additional findings made by the Examiner with respect to claim 2, but argues that "the Examiner does not state how such rational[ e] or reasoning made the present claimed invention obvious over a combination of references." Br. 28-29. However, as above, the Examiner provides a specific reason that a person of ordinary skill would have combined DePompei and Kordomenos. See Ans. 4. The Appellant's limited argument fails to show error in the Examiner's findings and conclusions, and it fails to show that making the proposed combination 7 L, Appeal2017-008910 Application 14/710,680 would have been beyond the ordinary level of skill in the art. See Jung, 637 F.3d at 1365. The Appellant's arguments with respect to claims 3-7, see Br. 29-30, are unpersuasive because they fail to address, or otherwise show error in, the Examiner's specific findings and conclusions concerning the subject matter of those claims, see Ans. 5-9. See Jung, 637 F.3d at 1365; In re Lovin, 652 ----------. - .. I '~ r::1111 ................................................ .. Appeal2017-008910 Application 14/710,680 determines that it would have been obvious to modify the composition of DePompei and Kordomenos to include Sawaguchi's rust-preventative to improve corrosion protection. Id. The Appellant argues that "nothing in the combination of Sawaguchi, DePompei, or Kordomenos implies or suggests that such rust preventive agents would be compatible with a coating composition comprising a polymeric binder that is made by reacting (a) an acetoacetoxy functional polyester epoxy block or graft copolymer and (b) an isocyanate functional crosslinking component." Br. 34. The Appellant also argues that "there is nothing in the cited references that would provide a logical reason to combine the references to achieve the invention claimed in claim 11." Id. The Appellant further argues that, because "[ t ]he present invention is not directed to rust preventive compositions," "a skilled artisan would not be motivated to use rust preventive pigments to achieve the present invention." Id. Those arguments are not persuasive. The reason to combine the references is, as suggested by Sawaguchi, enhanced corrosion resistance. The Appellant acknowledges that "[ t ]he use of Sawaguchi type pigments to prevent rust is known in the art." Br. 34. As explained above, Kordomenos is also concerned with corrosion resistance. E.g., Kordomenos at 4:52-53. The Appellant provides no reason to believe that a person of ordinary skill in the art would not have expected Sawaguchi's rust-preventative pigments to function as rust-preventative pigments in the composition of DePompei as modified by Kordomenos. The Appellant's assertion that "the present invention" is not concerned with rust prevention fails to indicate error in the Examiner's determination that a person of ordinary skill in the art would 9 Appeal2017-008910 Application 14/710,680 have been motivated to combine the references to reduce corrosion. See In re Beattie, 974 F.2d 1309, 1312 (Fed.Cir.1992) ("[T]he law does not require that the references be combined for the reasons contemplated by the inventor."). On this record, the Appellant has not identified reversible error in the rejection. See Jung, 637 F.3d at 1365. Rejection 3 Claim 21 depends from claim 20, which depends from claim 18. Claim 18 recites "[a] substrate coated" with the coating composition of claim 1. Claim 20 requires the substrate to be metal. Claim 21 requires the substrate to be aluminum. The Examiner finds that DePompei teaches the use of its composition as a coating, but does not specifically describe an aluminum substrate. Ans. 12. The Examiner finds that Ohrbom teaches a coating for automotive purposes which includes aluminum substrates, and that Ohrbom teaches suitable topcoats include polyesters, and particular polyesters with acetoacetoxy group and isocyanate crosslinkers. Id. Kordomenos specifically describes automotive applications for its composition, including application to metal substrates. E.g., Kordomenos at 3:34--35. The Examiner determines that it would have been obvious to apply the compositions of DePompei as modified by Kordomenos to aluminum substrates, given that Ohrbom teaches the use of similar compositions as suitable coatings for aluminum substrates. Ans. 12. The Appellant argues that, in comparison to Ohrbom, "[ t ]he present invention uses an entirely different polymeric binder coating composition to coat metal substrates," and that nothing in the references "suggest[ s] or predict[ s] the claimed coating composition." Br. 3 8. 10 Appeal2017-008910 Application 14/710,680 Those arguments are not persuasive. The Appellant does not dispute that Ohrbom teaches coating compositions including polyesters, and, in particular, polyesters with acetoacetoxy group and isocyanate crosslinkers. See Ans. 12. Those coating compositions are similar to the coating compositions of both DePompei and Kordomenos. As noted above, Kordomenos specifically describes use of its composition on metal automotive substrates. Even assuming the Appellant accurately identifies certain differences among the three references, Br. 37-38, the Appellant does not persuasively explain why those differences would have caused a person of ordinary skill to doubt whether the coating composition of DePompei and Kordomenos could be applied to an aluminum substrate, and the similarities among the references provides at least a reasonable expectation of success that the coating could successfully be used on a metal substrate. The Appellant has not identified reversible error in the rejection. See Jung, 637 F.3d at 1365. Rejection 4 Claims 21 and 22 are subject to Rejection 4. Claim 21 is described above in our discussion of Rejection 3. Claim 22 depends from claim 20 and specifies that the metal substrate is chrome pretreated aluminum. The Examiner finds that Mosser teaches the use of organic coatings for metal substrates, and that polyesters are suitable organic resins for such coatings. Ans. 12. The Examiner finds that Mosser teaches that such coatings may be applied to chrome treated aluminum. Id. at 12-13. The Examiner determines that it would have been obvious to use the composition of DePompei as modified by Kordomenos on Mosser's substrate because 11 Appeal2017-008910 Application 14/710,680 Mosser teaches the use of similar polyester coatings on chrome pretreated aluminum substrates. Id. at 13. The Appellant generally raises arguments similar to those described above, e.g., that the present invention uses a different binder than Mosser, and that the references do not disclose the claimed coating composition. Br. 41--42. Those arguments are not persuasive. Mosser teaches coatings that provide improved corrosion resistance. As set forth above, Kordomenos is also concerned with corrosion resistance, and a person of ordinary skill in the art would have combined DePompei and Kordomenos with the expectation of achieving a composition with corrosion resistance. Given the known use of corrosion resistant coatings on chrome pretreated aluminum substrates, the Appellant's limited arguments do not persuade us of reversible error in the Examiner's proposed combination. In particular, DePompei teaches the use of its composition as a coating but does not specify a metal substrate. Kordomenos specifies metal substrates. Mosser also describes metal substrates for corrosion resistant coatings, and specifically identifies chrome pretreated aluminum substrates. Absent some reason a person of ordinary skill in the art would not have expected the corrosion resistant coating of DePompei as modified by Kordomenos to work on chrome pretreated aluminum, the record reasonably suggests that the coating of DePompei as modified by Kordomenos could be used on any metal substrate in need of corrosion resistance, including chrome pretreated aluminum. The Appellant has not identified reversible error in the rejection. See Jung, 637 F.3d at 1365. 12 Appeal2017-008910 Application 14/710,680 CONCLUSION We AFFIRM the Examiner's rejections of claims 1-7, 10, 11, and 18- 22. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a). AFFIRMED 13 Copy with citationCopy as parenthetical citation
