PRAISS, and MICHELLE N. ANKENBRAND, Administrative Patent Judges. PRAISS, Administrative Patent Judge. DECISION ON APPEAL1 Pursuant to 35 U.S.C. § 134(a), Appellant2 appeals from the Examiner’s decision to reject claims 1–12, 15–33, 36–55, 58–76, and 79–87. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. 1 In this Decision, we refer to the Specification filed Nov. 25, 2014 (“Spec.”), the Final Office Action dated Sept. 5, 2018 (“Final Act.”), the Appeal Brief filed Feb. 27, 2019 (“Appeal Br.”), the Examiner’s Answer dated May 2, 2019 (“Ans.”), and the Reply Brief filed July 1, 2019 (“Reply Br.”). 2 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies Chemcoaters, LLC as the real party in interest. Appeal Br. 3. Appeal 2019-005466 Application 14/553,864 2 STATEMENT OF THE CASE The invention relates to a process for making a corrosion-resistant coating for zinc or zinc-alloy coated substrates that meets the American Society of Testing and Materials International ASTM B1117-11 (ASTM B1117) standard for continuous salt spray tests of metals and coated metals. Spec. ¶ 2. According to the Specification, zinc coatings protect the underlying steel by providing both a physical barrier and cathodic protection, however, existing hot-dip coating processes produce hazardous by-products which, in turn, require laborious and expensive disposal. Id. ¶¶ 6, 11. The Specification states the disclosed process provides for a dry-in- place application, negating the requirement for hazardous waste disposal. Id. ¶ 12. Claim 1, reproduced below, is illustrative of the subject matter on appeal (disputed limitations italicized). 1. A process for making a corrosion-resistant metal component comprising the steps of: combining water, at least one zinc phosphate forming compound and at least one chromium forming compound to form a first solution; separately combining at least one silicate compound with water to form a second solution; combining the first solution with the second solution such as to form a mixed aqueous solution; combining the mixed aqueous solution with at least one acrylic resin to form a coating mixture; and applying the coating mixture to a metal substrate having a zinc or zinc-alloy surface to form a coating on the metal substrate that reacts with the zinc or zinc-alloy surface of the metal substrate forming a covalent bond with the zinc or zinc- alloy Appeal 2019-005466 Application 14/553,864 3 surface, and the coating providing chemical resistance for at least 150 hours in accordance with ASTM B117 standards where the zinc or zinc-alloy coating of the metal substrate has a weight of 0.04 oz/ ft2 (12.20 g/ m2). Appeal Br. 21 (Claims Appendix). ANALYSIS We review the appealed rejections for error based upon the issues Appellant identifies, and in light of the arguments and evidence produced thereon. 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) (“[I]t has long been the Board’s practice to require an applicant to identify the alleged error in the examiner’s rejections.”). After considering the argued claims and each of Appellant’s arguments, we are not persuaded of reversible error in the appealed rejections. The Examiner maintains the rejection of claims 1–12, 15–33, 36–55, 58–76, and 79–87 under 35 U.S.C. § 103(a) over the following prior art references: Name Reference Date Tsutsui US 4,169,916 Oct. 2, 1979 Krippes US 2013/0136947 A1 May 30, 2013 Appellant argues claims 1–12, 15–33, 36–55, 58–76, and 79–87 subject to the rejection as a group. Appeal Br. 3–8. Therefore, claims 2–12, 15–33, 36–55, 58–76, and 79–87 stand or fall with claim 1. 37 C.F.R. § 41.37(c)(1)(iv). Appellant contends the Examiner erred in rejecting claim 1 for two reasons: (1) Krippes is not prior art because the claims are fully supported by Appeal 2019-005466 Application 14/553,864 4 (and therefore entitled to the priority date of) its earlier filed disclosure, and (2) the combination with Tsutsui would not have been obvious based on unexpected results (superior corrosion resistance) and because it would have rendered Krippes unsatisfactory for its intended purpose. Appeal Br. 10–19. Appellant’s arguments do not persuade us the Examiner reversibly erred in rejecting claim 1 as obvious over the teachings of Krippes in view of Tsutsui. Krippes is Prior Art to Claim 1 The Examiner finds that Appellant’s application is not entitled to the benefit of Krippes’ filing date (and therefore Krippes is prior art) because Krippes “discloses using zinc phosphate to make a solution containing zinc phosphate,” whereas claim 1 “recite[s] using [a] zinc phosphate forming compound to make a solution containing zinc phosphate.” Final Act. 4 (emphasis omitted). The Examiner determines that the scope of claim 1, therefore, is broader than the scope of Krippes. Id. The Examiner further finds that although Krippes has written description support for using zinc phosphate to make a solution containing zinc phosphate, Krippes does not have written description support for “using a compound that is not zinc phosphate to make a zinc phosphate containing solution.” Id. Appellant argues a person having ordinary skill in the art would “interpret” Krippes’ “zinc phosphate compound” to be “a compound that provides for the [same] reaction between the coating mixture and the zinc or zinc-alloy surface of the metal substrate” that is disclosed in Appellant’s Specification. Appeal Br. 12–13 (citing Spec. ¶ 14). Appellant directs us to Krippes’ disclosure of a reaction between the coating mixture and the surface of the metal substrate. Id. at 13 (quoting Krippes ¶ 13 (“The coating Appeal 2019-005466 Application 14/553,864 5 mixture is capable of reacting with the zinc or zinc-alloy surface of the metal substrate forming a chemical bond with the zinc or zinc-alloy surface.”)); Reply Br. 3–5. Appellant argues the Examiner’s interpretation of claim 1’s “zinc phosphate forming compound” meaning “using [a] zinc phosphate forming compound to make a solution containing zinc phosphate” lacks support in the Specification because “the phosphate would not be able to react with the zinc or zinc-alloy surface of the metal component.” Appeal Br. 14. According to Appellant, the Specification’s “rewording of the term ‘zinc phosphate compound’ to ‘zinc phosphate forming compound’ did not change the meaning of the term, and thus, does not constitute new matter.” Id. (emphasis omitted). Appellant further contends that Krippes reasonably conveys to a person having ordinary skill in the art that the inventors had possession of the claimed invention as of Krippes’ filing date because the Specification and Krippes share the same data and drawings. Id. at 15. The purpose of the written description requirement is to convey with reasonable clarity to those skilled in the art that, as of the filing date sought, applicant was in possession of the invention as now claimed. Agilent Techs., Inc. v. Affymetrix, Inc., 567 F.3d 1366, 1379 (Fed. Cir. 2009); Vas-Cath, Inc. v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed. Cir. 1991). The possession test alone, however, is not always sufficient to meet the written description requirement. Enzo Biochem, Inc. v. Gen-Probe Inc., 323 F.3d 956, 969 (Fed. Cir. 2002). Rather, “the written description requirement is satisfied by the patentee’s disclosure of ‘such descriptive means as words, structures, figures, diagrams, formulas, etc., that fully set forth the claimed invention.’” Id. (quoting Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. Appeal 2019-005466 Application 14/553,864 6 1997)). Importantly, it is not a question of whether a person having ordinary skill in the art might perform the claimed invention based on the disclosure’s teachings, but whether the application necessarily discloses the claimed invention. Lockwood, 107 F.3d at 1572. Appellant’s arguments relate to the recited “coating mixture” and its function rather than the recited “zinc phosphate forming compound,” which is contained in “a first solution.” Appeal Br. 21 (Claims Appendix). The first solution is then combined with “a second solution” and “at least one acrylic resin” to ultimately “form a coating mixture.” Id. Focusing on the “zinc phosphate forming compound” recited in claim 1 instead, and comparing it to Krippes’ “zinc phosphate compound” that is used to form “a first solution,” we agree with the Examiner that the claimed “zinc phosphate forming compound” has a broader scope than Krippes’ “zinc phosphate compound.” Ans. 4. As the Examiner explains, the first solution combines water with a zinc phosphate forming compound, thus, “zinc phosphate forming compound” encompasses “anything that contains PO43- and/or Zn.” Id. The Examiner’s claim construction is consistent with the Specification, which discloses a compound containing PO43-, such as phosphoric acid, may be the phosphate coating component or “zinc phosphate forming compound.” Id. (citing Spec. ¶ 45). The overlap between the disclosures in Krippes and the Specification to which Appellant directs us is not persuasive of error because the pertinent inquiry is whether Krippes’ “zinc phosphate compound” reasonably conveys possession of a “zinc phosphate forming compound” in the first solution. In the Reply Brief, Appellant states that if “zinc phosphate forming compound” means a compound containing PO43- and Zn and Krippes’ “zinc phosphate Appeal 2019-005466 Application 14/553,864 7 compound” means “zinc phosphate,” then the term is fully supported by Krippes’ disclosure. Reply Br. 2. However, the term “zinc phosphate forming compound” is not limited to a compound containing PO43- and Zn. Instead, the term means a compound containing PO43- and/or Zn, which is broader than Krippes’ disclosure of PO43- and Zn (zinc phosphate). Ans. 4. Appellant does not direct us to any specific examples of a zinc phosphate compound in Krippes’ disclosure to suggest zinc phosphate compound is broader than zinc and phosphate. Therefore, claim 1 does not have written description support in Krippes’ disclosure and is not entitled to Krippes’ earlier filing date. Having determined that it is appropriate to consider the Examiner’s rejection based on Krippes as a prior art reference, we turn to the Examiner’s combination of Krippes and Tsutsui. Obviousness over the Prior Art The Examiner finds Krippes’ teaches all of claim 1’s limitations, except that Krippes discloses incorporating zinc phosphate in the first solution instead of incorporating a zinc phosphate forming compound in the first solution, as claim 1 recites. Non-Final Action dated Feb. 8, 2018 (“Non- Final Act.”) 4–5; see Final Act. 3 (rejecting the claims over Krippes and Tsutsui “for the same reasons as stated in the previous Office action dated 02/08/2018”). The Examiner finds that Tsutsui teaches a composition for zinc-coated metal that contains, inter alia, phosphoric acid. Non-Final Act. 5. The Examiner further finds that Tsutsui “discloses that both phosphoric acid and phosphate can be used to improve the corrosion resistance” and concludes that it would have been obvious to one of ordinary skill in the art Appeal 2019-005466 Application 14/553,864 8 to replace Krippes’ zinc phosphate with phosphoric acid to make a coating composition having high corrosion resistance. Id. at 6. Appellant argues Krippes’ zinc phosphate cannot be replaced with Tsutsui’s teaching to use phosphoric acid in a coating composition having high corrosion resistance because Tsutsui’s Example 1 achieved corrosion resistance for 70 hours and the claimed method’s superiority and unexpected results (“chemical resistance for at least 150 hours”) rebuts a prima facie case of obviousness. Appeal Br. 17–18. Appellant asserts that comparing Krippes’ coating properties to Tsutsui’s Example 1 is appropriate because neither the testing standards used nor the zinc-coating amounts used distinguish the two. Id. at 18. Appellant also contends that Tsutsui’s coating solution contains at least one or more lithium silicates, which allegedly are highly reactive and would lead to the formation of unwanted compounds. Id. at 19. For this reason, Appellant argues that Tsutsui not only teaches away from the claimed method, but renders modification of Krippes unsatisfactory for its intended purpose. Id. Appellant’s arguments are not persuasive of error because the record supports the Examiner’s finding that Tsutsui teaches the interchangeability of using either phosphoric acid or phosphate to improve corrosion resistance. Ans. 9; Tsutsui 3:35–45 (“For the purpose of further improving corrosion resistance, at least one agent selected from . . . phosphoric acid and phosphate are added to the above-mentioned solution.”). In view of Tsutsui’s teaching, a person having ordinary skill in the art would have expected Krippes’ coating to exhibit corrosion resistance regardless of whether phosphoric acid or phosphate is used in the first solution. In other Appeal 2019-005466 Application 14/553,864 9 words, based on the cited record in this Appeal, a person of ordinary skill in the art would have expected phosphate and phosphoric acid to be equivalents. Appellant has not adequately explained why its claimed coating is unexpectedly superior with respect to corrosion resistance. Ans. 8. Appellant directs us to Tsutsui’s Example 1 having corrosion resistance of 70 hours, which is less than half of the 150 hours recited in claim 1 (Appeal Br. 17), however, Appellant does not show that Tsutsui’s Example 1includes either phosphate or phosphoric acid. Thus, Appellant does not compare its results with the closest prior art. “[W]hen unexpected results are used as evidence of nonobviousness, the results must be shown to be unexpected compared with the closes prior art.” In re Baxter Travenol Labs., 952 F2d 388, 392 (Fed. Cir. 1991). Appellant’s argument that Tsutsui’s coating contains lithium silicate, which would have led to the formation of unwanted compounds and rendered modification of Krippes unsatisfactory for its intended purpose is not persuasive of error because it is not supported by evidence. It is well settled that arguments of counsel cannot take the place of factually supported objective evidence. See, e.g., In re Huang, 100 F.3d 135, 139–40 (Fed. Cir. 1996); In re De Blauwe, 736 F.2d 699, 705 (Fed. Cir. 1984). Moreover, the record does not support Appellant’s position. The record supports the Examiner’s finding that Tsutsui teaches the lithium ion itself contributes to the formation of a film with superior corrosion resistance. Ans. 9; Tsutsui 2:44–56. Appellant does not dispute this finding in the Reply Brief. The preponderance of the evidence in this appeal record, therefore, supports the Examiner’s conclusion that the claimed subject matter would Appeal 2019-005466 Application 14/553,864 10 have been obvious over Krippes’ method in view of Tsutsui’s teaching the interchangeability of using either phosphoric acid or phosphate to improve corrosion resistance. Accordingly, we affirm the Examiner’s rejection of claim 1 under 35 U.S.C. § 103(a) for the above reasons. Because we find Appellant’s arguments unpersuasive of error in the Examiner’s rejection of claim 1 for the reasons discussed above, we likewise affirm the Examiner’s rejection of claims 2–12, 15–33, 36–55, 58–76, and 79–87 for the same reasons. CONCLUSION For these reasons and those the Examiner provides, we uphold the Examiner’s rejection of claims 1–12, 15–33, 36–55, 58–76, and 79–87 under 35 U.S.C. § 103(a) as obvious over the cited prior art references.
