TIMM, JENNIFER R. GUPTA, and JANEE. 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 1-9 and 11-242. We have jurisdiction over this appeal under 35 U.S.C. § 6(b ). We AFFIRM. STATEMENT OF THE CASE Appellant's invention is generally directed to a primer composition that improves the adhesion of tapes to hydrophilic surfaces, such as glass. 1 Appellant is the Applicant, Tesa SE, which, according to the Appeal Brief, is the real party in interest. Appeal Brief filed September 12, 201 7 ("Br."), 2. 2 Final Office Action entered March 13, 2017 ("Final Act."). Appeal2018-003019 Application 14/640,835 Spec. 1, 11. 1-2. Independent claims 1 and 20 illustrate the subject matter on appeal and are reproduced below with contested language italicized: 1. A primer comprising a mixture dissolved or dispersed in one or more organic solvents which solvents is isopropanol or which contains isopropanol, the mixture comprising: one or more organofunctional silanes; and, a copolymer obtained through the free-radical copolymerization, of vinylcaprolactam and/or vinylpyrrolidone, and one or more of the following monomers: a) an acrylic acid ester of a linear primary alcohol containing 2 to 10 carbon atoms in the alkyl group of the alcohol, b) an acrylic acid ester of a branched, non-cyclic alcohol having 4 to 12 carbon atoms in the alkyl group of the alcohol, c) acrylic acid, and wherein the primer is free of chlorinated polyolefins. 20.

Claims Appendix filed October 6, 2017 ( emphasis added). The Examiner maintains the following rejections in the Examiner's Answer entered November 1, 2017("Ans."): 2 Appeal2018-003019 Application 14/640,835 I. Claims 1-7, 11, 12, and 14--19 under 35 U.S.C. § I03(a) as unpatentable over Groves (US 5,677,376, issued October 14, 1997) in view of Ogawa et al. (US 2008/0032055 Al, published February 7, 2008); II. Claims 8, 9, and 20-24 under 35 U.S.C. § I03(a) as unpatentable over Groves in view of Ogawa and Ilkka et al. (US 2005/0081993 Al, published April 21, 2005); and III. Claim 13 under 35 U.S.C. § I03(a) as unpatentable over Groves in view of Ogawa and Zhang (US 6,984,287 B2, issued January 10, 2006). DISCUSSION Upon consideration of the evidence relied upon in this appeal and each of Appellant's contentions, we affirm the Examiner's rejections of claims 1-9 and 11-24 under 35 U.S.C. § I03(a) for the reasons set forth in the Final Action, the Answer, and below. We review appealed rejections for reversible error based on the arguments and evidence Appellant provides for each ground of rejection Appellant contests. 3 7 C.F .R. § 41.3 7 ( 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 Appellant argues claims 1-7, 11, 12, and 14--19 as a group. Br. 5-9. We accordingly select claim 1 as representative, and decide the appeal as to claims 1-7, 11, 12, and 14--19 based on claim 1 alone. 37 C.F.R. § 4I.37(c)(l)(iv). 3 Appeal2018-003019 Application 14/640,835 Groves discloses polymer blends that that can be used as primers and comprise a modified block copolymer and a polymer comprising a polymerization reaction product of two or more mono-ethylenically unsaturated monomers in which at least one of the monomers is an acrylic or methacrylic acid ester of a non-tertiary alcohol having 1 to 14 carbon atoms, and at least one of the monomers is a nitrogen-containing monomer. Col. 1, 11. 24--40; col. 2, 11-18. Groves discloses that preferred polymer blends include a blend of maleated styrene-ethylene/butylene-styrene block copolymer and iso-octyl acrylate/N-vinylcaprolactam/acrylic acid polymer (corresponding to a copolymer as recited in claim 1). Col. 3, 11. 52-56. Groves discloses that additives such as silanes and chlorinated polyolefins may be included in the polymer blends. Col. 4, 11. 45--46. Example 1 of Groves describes a process for preparing a polymer blend that involves dissolving a block copolymer and a terpolymer consisting of iso-octyl acrylate/N-vinylcaprolactam/acrylic acid ( corresponding to a copolymer as recited in claim 1) in a solvent blend of cyclohexane, xylene, and ethanol. Col. 8, 11. 20-61. Example 15 of Groves describes a process for preparing a primer solution that involves adding chlorinated polypropylene, a silane coupling agent, and triethanolamine titanate to the polymer blend of Example 1, and diluting the solution with a solvent mixture of cyclohexane, xylene, and ethanol. Col. 11, 11. 23-36. The Examiner finds that "Groves discloses all the limitations set forth in claim 1 but fails to exemplify a primer containing the polymer blend, the solvents and the silane coupling agent but is free of chlorinated polyolefins." Ans. 3--4 (citing Groves Abstract; col. 3; col. 4, 11. 45--46; Example 15). The Examiner finds, however, that Ogawa discloses that chlorinated polyolefin 4 Appeal2018-003019 Application 14/640,835 resins produce pollutive gas, such as dioxin, and discloses use of a non- chlorinated polyolefin resin in a primer composition to avoid the pollutive effect of chlorinated polyolefins. Ans. 4 ( citing Ogawa Abstract; ,r 5). The Examiner concludes that "it would have been obvious to a person having ordinary skill in the art at the time the instant invention was made to have modified the primer taught by Groves by doing away with the optional chlorinated polyolefins so as to render the primer more health-friendly and environment-friendly." Ans. 4. Appellant argues that the only compositions disclosed in Groves that include a silane-the compositions of Examples 15 and 24---necessarily also include a chlorinated polypropylene. Br. 6. Appellant argues that one of ordinary skill in the art would have known that chlorinated polyolefins provide a significant adhesion-promoting effect in primers, and omission of a chlorinated polyolefin from Groves' compositions, therefore, would have been illogical and contrary to what one of ordinary skill in the art would have considered doing. Br. 6-7. Appellant's arguments, however, do not take into consideration Groves' disclosures as a whole, which are not limited to Examples 15 and 24. In re Fracalossi, 691 F.2d 792, 9974 n.1 (CCPA 1982) (explaining that a prior art disclosure is not limited to its examples); In re Applied Materials, Inc., 692 F.3d 1289, 1298 (Fed. Cir. 2012) ("A reference must be considered for everything that it teaches, not simply the described invention or a preferred embodiment."). As discussed above, Groves broadly discloses that additives such as silanes and chlorinated polyolefins may be included in the polymer blends described in the reference, indicating that inclusion of such components in the polymer blends is optional. We find no disclosure in 5 Appeal2018-003019 Application 14/640,835 Groves indicating that a cholorinated polyolefin must be included in the polymer blends described in the reference. Nor do we find any disclosure in Groves indicating that a silane must be used in combination with a chlorinated polyolefin. As also discussed above, Ogawa discloses that cholorinated polyolefin resins produce pollutive gas, and teaches using non- chlorinated polyolefin resins in primer compositions to avoid the pollutive effect of chlorinated polyolefins. In view of a combination of Groves' and Ogawa's disclosures as a whole, one of ordinary skill in the art may have included a silane in Groves' polymer blend, but would have omitted chlorinated polyolefins from the composition based on Ogawa's disclosure that cholorinated polyolefin resins produce pollutive gas, and Groves' indication that cholorinated polyolefins are an optional component of Groves' polymer blends. Although Appellant argues that one of ordinary skill in the art would have known that chlorinated polyolefins provide a significant adhesion- promoting effect in primers, and therefore would not have omitted a chlorinated polyolefin from Groves' polymer blend, on this appeal record, Appellant does not provide any evidence to support this assertion. It is well- established that unsupported attorney arguments cannot take the place of evidence necessary to resolve a disputed question of fact. In re Geisler, 116 F.3d 1465, 1470 (Fed. Cir. 1997) ("An assertion of what seems to follow from common experience is just attorney argument and not the kind of factual evidence that is required to rebut a prima facie case of obviousness."); Icon Health & Fitness, Inc. v. Strava, Inc., 849 F.3d 1034, 1043 (Fed. Cir. 2017) ("[a]ttorney argument is not evidence" and cannot rebut other admitted evidence) 6 Appeal2018-003019 Application 14/640,835 Appellant argues that "even when considered jointly with Groves, neither Ogawa [ n ]or Groves make any mention of isopropanol as an organic solvent in the primer." Br. 7. Appellant argues that "the primer of Ogawa is aqueous and is not based on an organic solvent which is, or which necessarily includes, isopropanol." Id. As discussed above, however, regardless of whether Ogawa discloses an aqueous solvent, Groves describes preparing a primer solution that includes, in part, a terpolymer consisting of iso-octyl acrylate/N- vinylcaprolactam/acrylic acid (corresponding to a copolymer as recited in claim 1 ), a silane coupling agent, and an organic solvent blend of cyclohexane, xylene, and ethanol. Although the solvent blend disclosed in Groves includes ethanol rather than isopropanol as recited in claim 1, one of ordinary skill in the art reasonably would have understood that isopropanol would be suitable for use in Groves' solvent blend due to its close structural similarity to ethanol, and the resulting expectation that isopropanol would have properties similar to those of ethanol. In re Payne, 606 F.2d 303, 313 (CCP A 1979) ("An obviousness rejection based on similarity in chemical structure and function entails the motivation of one skilled in the art to make a claimed compound, in the expectation that compounds similar in structure will have similar properties."); In re Deuel, 51 F. 3d 1552, 1558 (Fed. Cir. 1995) ("Structural relationships may provide the requisite motivation or suggestion to modify known compounds to obtain new compounds. For example, a prior art compound may suggest its homologs because homologs often have similar properties and therefore chemists of ordinary skill would ordinarily contemplate making them to try to obtain compounds with improved properties."). 7 Appeal2018-003019 Application 14/640,835 Accordingly, Groves' disclosure of an organic solvent blend including ethanol for a primer composition renders use of isopropanol in such a solvent blend prima facie obvious. In re Dillon, 919 F. 2d 688, 692 (Fed. Cir. 1990) ("[S]tructural similarity between claimed and prior art subject matter ... where the prior art gives reason or motivation to make the claimed compositions, creates a prima facie case of obviousness, and [] the burden (and opportunity) then falls on an applicant to rebut that prima facie case."). We find no evidence on this appeal record establishing the criticality of using an isopropanol solvent, or a solvent that contains isopropanol, in the primer composition recited in claim 1. In fact, Appellant's Specification indicates that "[p ]articularly suitable solvents for the primer of the present invention are alcohols or solvents containing alcohols, wherein a single alcohol or a mixture of two or more alcohols can be used. Among alcohols, isopropanol has proven to be particularly advantageous." Spec. 12, 11. 1--4. Thus, the Specification indicates that all alcohols are suitable for use as the solvent in Appellant's primer. Appellant argues that Ogawa discloses a primer formed with an aqueous solvent, while the primer disclosed in Groves includes an organic solvent. Br. 7-8. Appellant argues that one of ordinary skill in the art would have understood that "organic compounds such as the chlorinated polyolefins of Groves would be readily soluble in organic solvents, but such chlorinated polyolefins are less soluble in aqueous systems." Br. 8. Appellant contends that the "different solvent systems of Groves and Ogawa indicate fundamental incompatibility," such that combination of the references is improper. Br. 7-8. 8 Appeal2018-003019 Application 14/640,835 As discussed above, however, the Examiner's rejection is not based on a combination of the primer compositions, or components of the compositions, disclosed in Groves and Ogawa. Rather, the Examiner relies on Ogawa's disclosure of using a non-chlorinated polyolefin resin in a primer composition due to the fact that cholorinated polyolefin resins produce pollutive gas, such as dioxin, thus providing a reason to omit cholorinated polyolefins from the primer composition disclosed in Groves. Appellant argues that "[ u ]nexpectedly ... the present inventors have realized a remarkable improvement in that the claimed primer composition provides for omission of chlorinated polyolefins with little or no loss of adhesion-promoting properties." Br. 9. Appellant, however, does not direct us to any evidence whatsoever in support of this assertion of unexpected results. Br. 8-9. "It is well settled that unexpected results must be established by factual evidence. 'Mere argument or conclusory statements in the specification does not suffice."' Geisler at 1470 (quoting In re De Blauwe, 736 F.2d 699, 705 (Fed. Cir. 1994)); see also In re Pearson, 494 F.2d 1399, 1405 (CCPA 1974) ("Attorney's argument in a brief cannot take the place of evidence."). Accordingly, Appellant's unsupported argument does not meet the burden of establishing that the primer recited in claim 1 imparts results that would have been unexpected to one of ordinary skill in the art at the time of Appellant's invention relative to the closest prior art----Groves. In re Klosak, 455 F.2d 1077, 1080 (CCPA 1972) ("the burden of showing unexpected results rests on he who asserts them"); In re Baxter Travenol Labs., 952 F.2d 388, 392 (Fed. Cir. 1991) ("[W]hen unexpected results are used as evidence 9 Appeal2018-003019 Application 14/640,835 of nonobviousness, the results must be shown to be unexpected compared with the closest prior art."). Considering the totality of the evidence relied-upon in this appeal, a preponderance of the evidence weighs in favor of the Examiner's conclusion of obviousness. We accordingly sustain the Examiner's rejection of claims 1-7, 11, 12, and 14--19 under 35 U.S.C. § 103(a). Rejection II Appellant presents arguments for claims 8, 9, and 20-24 based on limitations included in both independent claim 20 and claim 1, from which claims 8 and 9 depend. Br. 9-12. We accordingly select claim 20 as representative, and decide the appeal as to claims 8, 9, and 20-24 based on claim 20 alone. 37 C.F.R. § 4I.37(c)(l)(iv). Independent claim 20 recites a primer comprising, in part, one or more organofunctional silanes selected from the group consisting of: vinyl- functional, amino-functional and glycydoxy-functional silanes. Appellant argues that neither Groves nor Ogawa disclose silanes having vinyl-functional, amino-functional, and glycydoxy-functional moieties. Br. 9-10. The Examiner, however, finds that although Groves discloses including silanes in the polymer blends described in the reference, "Groves fails to teach a glycidoxy- or amino- or vinyl-functional silane," and the Examiner relies on Ilkka for suggesting this feature. Ans. 4--5. Because Appellant's arguments are directed to Groves and Ogawa, and do not address the relied-upon disclosures in Ilkka, Appellant's arguments are unpersuasive of reversible error in the Examiner's rejection of claim 20. Appellant further repeats many of the arguments presented for claim 1, and argues that Ilkka does not overcome the shortcomings of 10 Appeal2018-003019 Application 14/640,835 Groves and Ogawa. Br. 10-12. Because we are unpersuaded of reversible error in the Examiner's rejection of claim 1 for the reasons discussed above, Appellant's arguments for claim 20 are also without merit. We accordingly sustain the Examiner's rejection of claims 8, 9, and 20-24 under 35 U.S.C. § 103(a). Rejection III To address this rejection, Appellant repeats many of the arguments presented for claim 1, and argues that Zhang does not overcome the shortcomings of Groves and Ogawa. Br. 12-13. Because we are unpersuaded of reversible error in the Examiner's rejection of claim 1 for the reasons discussed above, Appellant's position as to this rejection is also without merit. We accordingly sustain the Examiner's rejection of claim 13 under 35 U.S.C. § 103(a). DECISION We affirm the Examiner's rejections of claims 1-9 and 11-24 under 35 U.S.C. § 103(a). No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l )(iv). AFFIRMED 11 Copy with citationCopy as parenthetical citation
