KURTZ ____________ Appeal 2014-007599 Application 13/101,366 Technology Center 1700 ____________ Before PETER F. KRATZ, GEORGE C. BEST, and MONTÉ T. SQUIRE, Administrative Patent Judges. SQUIRE, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Appellants1 appeal the Examiner’s final rejection of claims 1–4 and 6–20. 35 U.S.C. § 134(a). We have jurisdiction under 35 U.S.C. § 6(b). For the reasons set forth below, we AFFIRM. 1 Appellants identify PPG Industries Ohio, Inc. as the real party in interest. Br. 1. Appeal 2014-007599 Application 13/101,366 2 The Claimed Invention Appellants’ disclosure relates to (1) a non-aqueous dispersion comprising a dispersion polymerization reaction product of an ethylenically unsaturated monomer and a polyester stabilizer, and an organic solvent, and (2) use of the disclosed non-aqueous dispersion in coatings. Spec. ¶ 1; Abstract. Independent claim 1 is representative of the claims on appeal and is reproduced below from the Claims Appendix to the Appeal Brief (Br. 6): 1. A non-aqueous dispersion comprising a) the dispersion polymerization reaction product of an ethylenically unsaturated monomer and a polyester stabilizer, and b) an organic solvent, wherein the ethylenically unsaturated monomer is substantially free of amine-functional monomers. The References The Examiner relies on the following prior art in rejecting the claims on appeal: Babjak et al., US 6,344,502 B1 Feb. 5, 2002 (hereinafter “Babjak”) Ambrose et al., US 2004/0132895 A1 July 8, 2004 (hereinafter “Ambrose”) Cooke et al., US 8,142,858 B2 Mar. 27, 2012 (hereinafter “Cooke”) Appeal 2014-007599 Application 13/101,366 3 The Rejections On appeal, the Examiner maintains2 the following rejections: 1. Claims 1–4 and 6–20 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Ambrose. 2. Claims 15 and 16 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Ambrose as applied to claim 14, and in further view of Cooke. OPINION3 1. Rejection of Claims 1–4 and 6–20 under 35 U.S.C. § 103(a) over Ambrose Appellants argue claims 1–4 and 6–20 as a group. We, therefore, select claim 1 as representative of this group, and the remaining claims stand or fall with claim 1. 37 C.F.R. § 41.37(c)(1)(iv) (2013). The Examiner finds that Ambrose teaches all of claim 1’s limitations. Ans. 2–4. The Examiner finds Ambrose discloses a coating composition comprising the reaction product of an ethylenically unsaturated monomer (e.g., (meth)acrylic acid, (meth)acrylates, etc.) and a polyester, wherein the polyester and monomer are dispersed in and react in an organic (i.e., non- aqueous) solvent, wherein the polyester is treated and/or selected to provide 2 The Examiner has withdrawn the rejection of claims 11 and 12 under 35 U.S.C. § 112, second paragraph, as indefinite, and the rejection of claims 1–4, 6–14, and 16–18 under 35 U.S.C. § 103(a) as unpatentable over Babjak. Adv. Act. 2, 4. Appellants cancelled claim 5. App. Br. 6. 3 We affirm the Examiner’s rejections for the reasons set forth in the Answer, which we adopt as our own. Nevertheless, we highlight and address specific findings and arguments for emphasis as follows. Appeal 2014-007599 Application 13/101,366 4 compatibility with the ethylenically unsaturated components in order to prevent phase separation of the polyester and acrylic components. Ans. 2 (citing Ambrose ¶¶ 8, 16–17, 20, 22, 23). The Examiner further finds that Ambrose teaches that “[a]mine- functional monomers are not required” in its coating composition and that the “coating composition further contains additives (e.g., pigments, waxes, etc.).” Ans. 2. The Examiner also finds that because Ambrose’s coating compositions contain additives (e.g., waxes, pigments such as titanium dioxide, silica, etc.), which are typically insoluble in the disclosed organic solvents, the disclosed coating compositions constitute “non-aqueous dispersions,” as recited in claim 1. Id. at 3–4. Additionally, the Examiner finds Ambrose teaches that “the coating composition is bisphenol A free and is suitable for coating substrates to form packaging materials (e.g., metal cans, etc.).” Adv. Act. 3 (citing Ambrose ¶¶ 9, 30–34). The Examiner concludes it would have been obvious to one of ordinary skill in the art at the time the invention to use bisphenol A-free coating compositions as disclosed in Ambrose to produce coated packaging materials for food applications. Ans. 3. Appellants argue that “Ambrose does not teach a dispersion comprising particles of any size dispersed in a continuous phase” because Ambrose does not explicitly use the “word ‘particle’” and because the “word ‘dispersion’ occurs only in the examples when referencing a particular wax dispersion.” App. Br. 2. We are not persuaded by Appellants’ arguments. That Ambrose does not explicitly use the term “particle” is unpersuasive because in comparing a prior art reference to the claimed invention, the important comparison is of the substance of the claim, under its broadest reasonable interpretation in Appeal 2014-007599 Application 13/101,366 5 light of the Specification, and the substance of the relied-upon disclosure in the prior art reference. In re Gleave, 560 F.3d 1331, 1334 (Fed. Cir. 2009) (holding that a reference does not have to satisfy an ipsissimis verbis test to disclose a claimed element). Moreover, as the Examiner found (Ans. 6), although Ambrose does not explicitly use the term “particle,” the presence of particles in the disclosed coating compositions is implicitly taught by Ambrose in light of its teaching that the disclosed coating composition allows for the presence of conventional additives such as pigments. Ambrose ¶ 28. In particular, as the Examiner further found (Ans. 6), pigments would have been generally understood by those skilled in the art to refer to colorants which are insoluble in the medium (e.g., liquid solvent) in which they are contained and typically in particulate or colloidal form. See Ambrose ¶¶ 27 (disclosing “suitable” solvents), 28 (disclosing “conventional additives such as pigments”), 29 (referring to certain coating composition components as “Solids” and explaining that these solids would have been understood by those skilled in the art to include “other additives and the like”). As the Examiner also found (Ans. 6) and Appellants do not challenge, it would have been known in the art that pigments typically used in coating applications include inorganic pigments (e.g., titanium dioxide, silica, zinc oxide, calcium carbonate, carbon black, etc.) which are particulate in form and insoluble in most conventional coating solvents. We discern no reversible error in the Examiner’s findings in this regard. Appellants’ argument that Ambrose uses the term “dispersion” only when referring to certain examples is unpersuasive because Ambrose’s teachings are not limited to the disclosures in its examples. See In re Mills, 470 F.2d 649, 651 (CCPA 1972) (“[A] reference is not limited to the Appeal 2014-007599 Application 13/101,366 6 disclosure of specific working examples.”). Appellants’ argument is also unpersuasive because, as noted by the Examiner (Ans. 7), it is based on limitations (i.e., dispersed polymer particles) that do not appear in the claim. See In re Van Geuns, 988 F.2d 1181 (Fed. Cir. 1993). Additionally, as the Examiner found (Ans. 2), Ambrose does teach a “non-aqueous dispersion,” inasmuch as claimed by Appellants. Ambrose ¶¶ 8, 16–17, 20, 22, 23, 27–30. As noted by the Examiner (Ans. 7), the claims, as presently drafted, do not require that the dispersed phase in the claimed dispersion be composed solely of the polymerization reaction product or any type of polymeric material. Indeed, as further noted by the Examiner (id.), claim 1 requires only that the recited polymerization product be present in the claimed non-aqueous dispersion. In fact, none of the claims specify the form of the dispersed phase or which particles in the composition constitute the dispersed phase. The claims also do not preclude an insoluble particle (i.e., a pigment) dispersed in a non-aqueous liquid phase from being the dispersed phase, as the Examiner found Ambrose teaches. Considering the teachings of the prior art and claim 1’s limitations under the broadest reasonable interpretation in light of the Specification, we discern no reversible error in the Examiner’s finding that Ambrose discloses a “non-aqueous dispersion,” as recited in the claim. Appellants argue that Ambrose fails to teach the claimed dispersion because “the word ‘polymerization’ appears only in the context of ‘copolymerization’ of an acrylic and polyester.” App. Br. 2. This argument is not well-taken because, as discussed above, a reference does not have to satisfy an “ipsissimis verbis test” to teach a claimed element. In re Gleave, 560 F.3d at 1334. Moreover, for the reasons previously discussed above, the Appeal 2014-007599 Application 13/101,366 7 Examiner’s finding that Ambrose teaches all the limitations of claim 1, including the “non-aqueous dispersion” limitation, is supported by sufficient evidence and based on sound technical reasoning. Ambrose ¶¶ 8, 16–17, 20, 22, 23, and 27–30. Appellants’ argument, without more, is insufficient to establish reversible error in the Examiner’s obviousness analysis and findings in this regard. Appellants argue that the Examiner “fails to make a prima facie case of obviousness” because the “Examiner has provided no evidence whatsoever that a dispersion polymerization reaction is occurring.” App. Br. 2–3. We do not find this argument persuasive. As the Examiner found (Ans. 9), the use of the term “dispersion polymerization” in claim 1 is a product-by-process limitation and thus, is not further limiting insofar as the structure of the claimed product. In re Thorpe, 777 F.2d 695, 698 (Fed. Cir. 1985). Accordingly, the patentability of Appellants’ claimed product does not depend on its method of production, i.e., via dispersion polymerization, as Appellants argue. Instead, as the Examiner found (Ans. 2–4), because Ambrose teaches all the limitations of the claimed product, the burden shifts to Appellants to show an unobvious difference between the claimed product and the prior art product. In re Marosi, 710 F.2d 798, 802 (Fed. Cir. 1993). Appellants, however, have failed to meet their burden. As noted by the Examiner (Ans. 10), Appellants do not identify evidence sufficient to show that the dispersion polymerization of the ethylenically unsaturated monomer and polyester stabilizer, as claimed, results in a materially different product from polymerization by other known polymerization methods (e.g., solution polymerization, etc.) disclosed in the prior art. Appellants’ argument that the “Examiner has provided no evidence Appeal 2014-007599 Application 13/101,366 8 whatsoever that a dispersion polymerization reaction is occurring” (App. Br. 2–3), without more, is insufficient to rebut the Examiner’s findings in this regard. Appellants argue Ambrose also fails to teach the claimed dispersion because “Ambrose teaches a solution” and a “graft copolymer in a solution is not a discrete particle dispersed in a separate continuous phase.” App. Br. 3. Appellants further argue that Ambrose fails to disclose a dispersion because it “teaches that the polyester and acrylic copolymer may be combined together in a coating without phase separation.” Id. We are not persuaded by these arguments. Appellants’ arguments are misplaced. As the Examiner found (Ans. 11) and contrary to Appellants’ argument, Ambrose teaches that the polymerization between the acrylic component and the polyester component takes place within a liquid medium and that some of the ungrafted polyester component and ungrafted acrylic component remains in the liquid medium. Ambrose ¶¶ 22, 23. There is no specific statement or teaching in Ambrose that the residual, ungrafted components are or must remain fully dissolved in solution, as Appellants’ argument suggests. Moreover, as the Examiner points outs (Ans. 7) and previously discussed above, the claims do not require that the dispersed phase of the claimed non-aqueous dispersion consist solely of the recited polymerization reaction product (i.e., grafted or ungrafted copolymer). As the Examiner found (id. at 2, 6, 7), Ambrose’s coating compositions are disclosed as the claimed non-aqueous dispersions due to the presence of insoluble components (e.g., pigments in particle form) dispersed in a continuous non- aqueous liquid phase. Ambrose ¶¶ 8, 16–17, 20, 22, 23, and 27–30. In light of Ambrose’s teachings and the Examiner’s findings in this regard, Appeal 2014-007599 Application 13/101,366 9 Appellants’ arguments regarding whether Ambrose teaches a solution and whether a graft copolymer is completely dissolved in the organic solvents disclosed in the Ambrose’s coating compositions are of no moment because they do not sufficiently address the Examiner’s rejection. Additionally, the portions of Ambrose that Appellants identify in the Appeal Brief (i.e., Ambrose ¶¶ 18, 22) as support for these arguments are unpersuasive and insufficient to establish reversible error in the Examiner’s findings in this regard. Appellants argue Ambrose does not teach all of claim 1’s limitations because “there is no teaching or suggestion whatsoever that the polyester of Ambrose is a stabilizer.” App. Br. 3. We do not find this argument persuasive. As noted by the Examiner (Ans. 15), the claims do not recite what property or characteristic or state is being stabilized by the polyester. Indeed, as further noted by the Examiner (id.), the claims require only that the polyester provide some type of stabilizing function. Considering the term “stabilizer” under the broadest reasonable interpretation in light of the Specification and Ambrose’s disclosure regarding the function and role of the polyester component in its coating composition, we discern no reversible error in the Examiner’s rationale and finding (id. at 2, 14–17) that Ambrose teaches claim 1’s “polyester stabilizer” limitation. As the Examiner found (Ans. 16), Ambrose teaches that a particular type of polyester can be used in the coating compositions to prevent incompatibility between certain of the coating compositions’ components. Ambrose ¶¶ 14–16, 18, and 20, 22. As the Examiner further found (Ans. 16), Ambrose also teaches that because the polyester component may be functionalized and/or modified in order to provide compatibility between the polyester and the acrylic components of Appeal 2014-007599 Application 13/101,366 10 the coating composition, it provides a stabilizing function to the composition. Ambrose ¶¶ 18–22. Appellants do not identify sufficient evidence to adequately rebut the Examiner’s analysis and findings in this regard. Appellants’ argument that “one skilled in the art will understand what is meant by the term ‘non-aqueous dispersion’ and ‘stabilizer’ in the context of a non-aqueous dispersion” (Reply Br. 2), without more, is insufficient to establish reversible error in the Examiner’s finding that Ambrose teaches claim 1’s “polyester stabilizer” limitation. Accordingly, we affirm the Examiner’s rejection of claims 1–4 and 6– 20 under 35 U.S.C. § 103(a) as unpatentable over Ambrose. 2. Rejection of Claims 15 and 16 under 35 U.S.C. § 103(a) over Ambrose as applied to Claim 14, and in further view of Cooke Appellants argue claims 15 and 16 as a group. Accordingly, we select claim 15 as representative of this group, and claim 16 stands or falls with claim 15. 37 C.F.R. § 41.37(c)(1)(iv) (2013). Claim 15 depends from claim 14 and adds the limitation: “wherein the crosslinker comprises phenolic.” App. Br. 7. The Examiner finds that Ambrose as applied to claim 14 teaches all the limitations of claim 15, except “wherein the crosslinker comprises phenolic.” Ans. 5. The Examiner relies on Cooke for teaching that limitation. Id. In particular, the Examiner finds Cooke teaches that it was “well known in the art to use crosslinkers (e.g., phenolic resin) in typical amounts of 5−30 wt% in bisphenol A-free polyester-based coatings for metal containers in order to provide durability and chemical resistance.” Id. (citing Cooke, col. 8, l. 17–col. 9, l. 32). Appeal 2014-007599 Application 13/101,366 11 The Examiner concludes it would have been obvious to one of ordinary skill in the art at the time the invention “to use effective amounts of known phenolic crosslinkers as disclosed in [Cooke] in the coatings of [Ambrose] in order to obtain food-safe coatings with the desired flexibility and durability required for a given end-use.” Ans. 5. Appellants argue that the Examiner’s rejection of claim 15 based on the combination of Ambrose and Cooke should be reversed because “Cooke does not overcome the shortcomings of Ambrose.” App. Br. 4–5. In particular, Appellants argue that Cooke “fails to teach the formation of a dispersion polymerization reaction product as presently claimed.” Id. at 5. We do not find this argument persuasive because Appellants fail to identify sufficient evidence or provide an adequate technical explanation to support it, and attorney argument cannot take the place of evidence. See In re De Blauwe, 736 F.2d 699, 705 (Fed. Cir. 1984). Appellants’ argument regarding Cooke’s teaching is also misplaced because, as discussed above, the Examiner does not rely on Cooke for teaching “the formation of a dispersion polymerization reaction product,” as Appellants’ argument suggests. Moreover, the Examiner’s findings regarding the combined teachings Ambrose and Cooke and rationale for why one of ordinary skill would combine the teachings of these references to arrive at Appellants’ claimed invention are well-supported by the record and based on sound technical reasoning. Ambrose ¶¶ 8, 16–17, 20, 22, 23; Cooke, col. 8, l. 17–col. 9, l. 32. Appellants’ argument, without more, is insufficient to establish reversible error in the Examiner’s findings and conclusion in this regard. Appeal 2014-007599 Application 13/101,366 12 Accordingly, we affirm the Examiner’s rejection of claims 15 and 16 under 35 U.S.C. § 103(a) as unpatentable over the combination of Ambrose and Cooke. DECISION/ORDER The Examiner’s rejections of claims 1–4 and 6–20 under 35 U.S.C. § 103(a) are affirmed. It is ordered that the Examiner’s decision is affirmed. 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 Copy with citationCopy as parenthetical citation
