KRATZ, and MARK NAGUMO, Administrative Patent Judges. NAGUMO, Administrative Patent Judge. DECISION ON APPEAL1 1 See our Opinions in related Appeals 2010-008140 and 2010-003601. Appeal 2010-010391 Application 11/755,159 2 A. Introduction2 Chiu-Sing Lin, Shingo Tsuno, Rajat K. Agarwal, and Thomas Fay-Oy Lim (“Linâ€) timely appeal under 35 U.S.C. § 134(a) from the final rejection3 of claims 1-5, 7-14, 16, and 18-20, which are all of the pending claims. We have jurisdiction. 35 U.S.C. § 6. We AFFIRM-IN-PART. The subject matter on appeal is related closely to the subject matter in two other appeals before us, which we decide simultaneously: Appeal 2010-003601 (11/549,278, filed 13 October 2006, claiming the benefit of 60/730,351, filed 26 October 2005; “3601 Appealâ€). Appeal 2010-008140 (11/535,287, filed 26 September 2006, claiming the benefit of 60/730,351, filed 26 October 2005; “8140 Appealâ€). As will be discussed in more detail infra to the extent necessary to provide context and to resolve the dispositive issues in this appeal, certain major components are shared in various embodiments of the inventions covered by the appealed claims of the three applications. The claimed subject matter in each application relates to cured compositions said to be useful as gaskets, particularly in internal combustion engines or transmissions, where they may be exposed to motor oils or 2 Application 11/755,159, Polyacrylate Compositions, filed 30 May 2007, claiming the benefit under § 120 of copending application 11/535,287, which was filed 26 September 2006. (Spec. 1; oath). The Specification is referred to as the “159 Specification,†and is cited as “Spec.†The real party in interest is listed as Henkel Corp. (Appeal Brief, filed 8 February 2010 (“Br.â€), 8.) 3 Office action mailed 11 September 2009. Appeal 2010-010391 Application 11/755,159 3 transmission fluids. (Spec. 1 [0002]-[0003].) The contact with such hydrocarbon fluids is said to shrink the polyacrylate compositions often used for gaskets in such machines, due, e.g., to the dissolution of additives such as plasticizers. (Id. at 1-2 [0004].) The inventive compositions in each application are based on a bis-silyl-substituted hydrocarbyl diradical having at least one acrylate linkage (“bis-silyl componentâ€). (Id. at 6 [0022].) In specific embodiments, the hydrocarbyl diradicals are poly(meth)acrylates. (Id. at 7 [0025].) According to the 159 Specification embodiments of the bis-silyl compounds are available commercially. (Id.) According to the 159 Specification, polyacrylates useful for gaskets are often very viscous, and many known diluents are incompatible with the polyacrylates, being at best poorly soluble in, and therefore often phase- separating from, the polyacrylates. (Spec 2 [0005].) The problems of high viscosity and incompatibility are said to be overcome by including a sulfonate (claims 1-5, 7-14, 16, and 18-20) or phosphonate diluent (claims 19 and 20). (Spec. 3 [0011], 9 [0028] to [0029].) In certain embodiments, claimed compositions can contain an amine antioxidant having a specified phenylene diamine (“PDAâ€) or diphenyl amine (“DPAâ€) structure (id. at 9 [0031] to 12 [0036]; claims 2-5). In other embodiments, the claimed compositions contain shrinkage-reducing components such as polyolefins (Spec. 12 [0037] to 14 [0040]; claims 8-14, 16, and 18.) The 159 Specification teaches further that the shrinkage reducing component can be polyolefin particles, a reactive fluid, or a combination of the two (id. at 13 [0038]), although the reactive fluid does not appear to be further described. Embodiments of the antioxidant component and the shrinkage Appeal 2010-010391 Application 11/755,159 4 reduction component are said to be commercially available. (Id. at 10 [0032] to 12 [0033]); 13 [0039], respectively.) Compositions of the 287 Application of the 8140 Appeal are required to contain a specified amine antioxidant. (287 Spec. 2 [0006] to 3 [0008]; 7 [0023] to 10 [0028]; claim 1.) In certain embodiments of the 287 Application, a further shrinkage reducing component is required. (Id. at 11 [0029] to 12 [0032]; claims 7-12, 15, and 16.) The sulfonate ester and phosphonate ester diluents are neither claimed nor disclosed in the 287 Specification. Compositions of the 278 Application of the 3601 Appeal are required to contain the bis-silyl component and the shrinkage reducing component. The amine antioxidant, and the sulfonate ester and phosphonate ester diluents are neither claimed nor disclosed in the 278 Specification. Representative Claim 1 of the 159 Application reads: 1. An uncured gasket composition curable in place on a first surface, comprising: a (meth)acrylate component comprising a silyl- functionalized poly(acrylate); and a diluent embraced by the following structure: wherein Z is S, X and Y may be the same or different and may be hydroxy, alkyl, alkenyl, aryl, aralkyl, aralkenyl, alkoxy, alkenoxy and aryloxy and A is =O, or alkoxy, alkenoxy or aryloxy. Appeal 2010-010391 Application 11/755,159 5 (Claims App., Br. 61.) Claim 2 depends from claim 1 and specifies the structure of the silyl- functionalized poly(acrylate) to be wherein each R1 is independently selected from a Cl to C6 alkyl, each R2 is independently selected from a C1 to C6 alkyl, a is integer from 0-3, q is an integer from 2 to about 1,000, and A is a hydrocarbon diradical containing at least one (meth)acrylate linkage. (Claims App., Br. 61; Spec. 6 [0022].) Claim 3 depends from claim 1 and requires the presence of phenylene diamines (“PDAâ€) having structure (I) or diphenyl amines (“DPAâ€) having structure (II), respectively. These compounds, which are substantially the same as those described in the 287 Specification, are said to act as antioxidants. (Claims App., Br. 61-62; Spec. 9 [0031] to 12 [0036].) Claim 8 depends from claim 1 and adds the limitation that the composition further comprises “at least one component which reduces shrinkage of the cured composition upon exposure of the cured composition to a hydrocarbon fluid, wherein the component is present in an amount sufficient to reduce shrinkage of the cured composition when exposed to a hydrocarbon fluid.†(Claims App., Br. 63.) Appeal 2010-010391 Application 11/755,159 6 Independent claim 19 covers compositions in which the silyl functionalized poly(meth)acrylate has the structure shown in claim 2,4 and adds the functional limitation that a cured product of the silyl functionalized poly(meth)acrylate shrinks upon exposure to hydrocarbon fluid. Claim 19 further includes diluents in which Z is S or P (phosphorus), and requires the presence of the shrinkage-reducing composition recited in claim 8. (Claims App., Br. 65.) The Examiner has maintained the following grounds of rejection:5 A. Claims 1, 2, 7, 14, and 18 stand rejected under 35 U.S.C. § 103(a) in view of the combined teachings of Nakagawa6 and Sugiyama. 7 B. Claim 19 stands rejected under 35 U.S.C. § 103(a) in view of the combined teachings of Nakagawa and Siggel.8 C. Claims 3-5 stand rejected under 35 U.S.C. § 103(a) in view of the combined teachings of Nakagawa, Sugiyama, and Kollmann.9 4 In claim 19, R2 is defined more broadly, including up to C10 alkyl. 5 Examiner’s Answer mailed 5 May 2010 (“Ans.â€). 6 Yoshiki Nakagawa et al., Polymer, Processes for Producing Polymer, and Composition, U.S. Patent 6,930,147 B1 (16 August 2005) 7 Akira Sugiyama and Takuya Kunitomo, Highly Weatherable Moisture- Curable One-Component Polyurethane Compositions, U.S. Patent Application Publication US 2004/0010076 A1 (2004) 8 Erhard Siggel et al., Method of Producing Dimensionally-Stable Injection Molded Polyesters, U.S. Patent 3,504,080 (1970). 9 Georg Kollmann et al., Room-Temperature Vulcanizing Condensation- Crosslinking Silicone Rubbers, U.S. Patent 6,172,150 B1 (2001).

Claim 16 stands rejected under 35 U.S.C. § 103(a) in view of the combined teachings of Nakagawa, Sugiyama, Poppo and Bair.11 H. Claims 1-5, 7-14, 16, and 18-20 stand provisionally rejected under obviousness-type double patenting in view of claims 1, 3, 4, 6-13, and 15 of copending application 11/535,287, Nakagawa, and Sugiyama. I. Claims 1, 2, 8-13, 16, and 18-20 stand provisionally rejected under obviousness-type double patenting in view of claims 1-3, 5, 6, 27, and 30 of copending application 11/549,278, Nakagawa, Sugiyama, and Kollmann. The Examiner has withdrawn a rejection under § 112(1), as well as rejections in view of Kawakami (US 2006/0089431 A1) and Wingrove (US 4,767,809). (Ans. 3.) B. Discussion Findings of fact throughout this Opinion are supported by a preponderance of the evidence of record. 10 Joseph M. Poppo, Acrylic Adhesive Sealant and Leak Sealing Method, U.S. Patent 4,772,031 (1988). 11 Thomas I. Bair and Dimitri P. Zafiroglu, Article for Absorbing Liquids, U.S. Patent 4,965,129 (1990). Appeal 2010-010391 Application 11/755,159 8 Initially, we find that the only claims argued with reasonable specificity that we need consider are independent claims 1 and 19. The remaining appealed claims stand or fall with claim 1. 37 C.F.R. § 41.37(c)(1)(vii). We also find that Lin has not addressed the substantive merits of the provisional obviousness-type double patenting (“PODPâ€) rejections. Rather, Lin argues that the PODP rejections are not ripe for appellate review, and that “in the interest of judicial efficiency should be set aside until the allegedly conflicting claims issue and actual rejections are imposed.†(Br. 13.) In the Reply,12 Lin argues merely that the rejections are not under review. (Reply 2.) Two substantive issues resolve the prior art rejections in this appeal. First, because we hold that the Examiner erred harmfully in relying on Sugiyama as evidence that it would have been obvious to add sulfonate esters as plasticizers to the compositions suggested by Nakagawa, we reverse Rejections A, C, D, F, and G. Because we hold the Examiner erred harmfully in relying on either Siggel or Poppo as evidence of adding polyolefin or polyethylene particles, respectively, to compositions disclosed by Nakagawa, we reverse Rejections B and E.13 12 Reply Brief filed 30 June 2010. 13 For the reasons set out in related appeal 2010-008140, we are not persuaded of harmful error in the Examiner’s reliance on Nakagawa for evidence of the obviousness of the bis-silyl poly(meth)acrylate compounds, or in the Examiner’s reliance on Kollmann and Nakagawa as evidence of the obviousness of using aromatic amines recited in claims 3-5 as antioxidants. Appeal 2010-010391 Application 11/755,159 9 As the Examiner finds (Ans. 6), Nakagawa teaches (Nakagawa col. 23, ll. 42-45) that plasticizers are “not particularly restricted but, according to the physical property or appearance characteristic which is to be adjusted, use may be made of, for example, . . . .†Nakagawa names a variety of plasticizers, including carboxylic acid esters and phosphate esters such as tricresyl phosphate [(CH3-C6H4-O)3P(=O)] and tributyl phosphate [(Bu-O)3P(=O)] as suitable plasticizers for the disclosed curable compositions. (Id. at ll. 53-54.) Nakagawa does not, however, describe sulfonate esters as plasticizers for the compositions. (Ans. 6.) The Examiner relies on Sugiyama to correct this deficiency. Sugiyama describes moisture curable one-component compositions that will form a polyurethane resin upon curing. (Sugiyama 1 [0012].) Such materials are said to be useful as sealants, adhesives, and water-proofing materials for roofs. (Id. at [0002].) The disclosed compositions comprise a main component such as a polypropylene oxide with an isocyanate group at each end (id. at 1-2 [0022]); a photocurable material, such as unsaturated acrylic compounds; a hindered amine photostabilizer; and blocked amines that form primary or secondary amine groups upon exposure to moisture. (Id. at 1 [0012]-[0013].) A further preferred additive is a “thixotropy endowing agent†that comprises, in the most relevant embodiments, a polyurea compound. (Id. at [0015]-[0017], and [0019].) According to Sugiyama, the thixotropy endowing agent is prepared by dissolving the polyisocyanate and monoamine in an ester plasticizer inert to isocyanate and subjecting the mixture to conventional condensation conditions. (Id. at 4 [0057].) Appropriate plasticizers are said to include a number of Appeal 2010-010391 Application 11/755,159 10 carboxylic acid esters, sulfonate esters, and phosphate esters. (Id. at [0058] and 5 [0067].) According to Sugiyama, the compositions are prepared by mixing the components. (Sugiyama 5 [0070].) The photocurable material forms a film at the surface of the cured product, while the hindered amine photostabilizer absorbs UV radiation, thereby providing high weatherability for the cured product. (Id.) The blocked amine compound is said to provide adequate curability and also to react with the photocurable material, thereby further improving the weatherability. (Id. at [0072].) The polyurea thixotropy endowing agent is said to provide excellent storage stability and thixotropy (coating and filling workabilities) of the composition. (Id. at 6 [0073].) The Examiner argues that Sugiyama shows that phosphate esters and sulfonate esters are equivalent in their function as plasticizers, and that it would therefore have been obvious to use sulfonate esters in place of the phosphate esters taught by Nakayama as plasticizers in the silyl-terminated poly(meth)acrylate compositions. (Ans. 8.) Lin, however, argues that persons skilled in the arts of adhesives and sealants recognize that sealant formulations have different properties depending on the base resin, and that “minor formulation changes often result in major property changes.†(Br. 24, citing Petrie,14 464 and 469.) In contrast, the Examiner has not directed our attention to credible evidence that the polyurea-polyester- polyacrylic compositions described by Sugiyama would have been regarded as sufficiently similar to the silyl-terminated poly(meth)acrylate 14 EDWARD M. PETRIE, HANDBOOK OF ADHESIVES AND SEALANTS (McGraw- Hill 2000), excerpt filed in the Evidence Appendix to the Brief. Appeal 2010-010391 Application 11/755,159 11 compositions suggested by Nakagawa as to provide a suggestion for the substitution or a reasonable expectation that the plasticizer substitution would be successful. Given the extremely broad suggestion of plasticizers by Nakagawa for a very broad range of polymeric compositions, and the relatively narrow disclosure of plasticizers by Sugiyama for a much narrower range of polymers, we find the weight of the evidence of record supports Lin. Moreover, the Examiner has relied on no reference other than Sugiyama for the use of sulfonate esters as plasticizers. Accordingly, we REVERSE all rejections based on Sugiyama. To reject claim 19, which requires, inter alia, the presence of a hydrocarbon-induced shrinkage reducing component, the Examiner (Rejection B) relies15 on Siggel as evidence that it would have been obvious to use high molecular weight polymers of C3-6 monoolefins as a filler for bis- silyl terminated polyacrylates suggested by Nakagawa in order to obtain a significant improvement in dimensional stability, i.e., reduction in shrinkage. (Ans. 6-7.) The difficulty with the Examiner’s argument is that Siggel is concerned with the dimensional stability of injection-molded polyesters such as polyethylene terephthalate (“PETâ€). (Siggel col. 1, ll. 19-32 and 54-61.) The weight of the evidence of record indicates, however, that PET is highly resistant to many hydrocarbon liquids.16 The Examiner has not directed our 15 These arguments also apply to claim 8 and its dependent claims, which we need not consider separately due to the Examiner’s improper reliance on Sugiyama. 16 EASTMAN CHEMICAL CO., CHEMICAL RESISTANCE OF EASTMAN PET 9921 (Eastman 2007), Table at 2, presented in the Evidence Appendix to the Brief. Appeal 2010-010391 Application 11/755,159 12 attention to any credible evidence in the record that the ordinary worker would have recognized, in the rather different poly(meth)acrylate-based gasket materials suggested by Nakagawa, a structure or chemistry that would have lead to problems similar to those confronted by Siggel. Although the Examiner notes the disclosure of fillers by Nakagawa (Ans. 6; see Nakagawa col. 23, ll. 9-42, the Examiner has not established a correspondence in chemical composition or in function between any of the fillers described by Nakagawa, which do not include polyolefin resins, with the polyolefin fillers described by Siggel. Nor has the Examiner come forward with any credible evidence that a polyolefin filler would have been suitable for obtaining high strength cured products (Nakagawa col. 23, ll. 22-29, listing fillers such as fumed silica) or for obtaining low strength but high elongation cured products (id. at ll. 30-36, listing fillers such as titanium oxide). Accordingly, we REVERSE the rejections based on the combined teachings of Nakagawa and Siggel. Further regarding claim 19, the Examiner also relies on Poppo (Rejection E) as evidence that it would have been obvious to add polyethylene particles to the silyl-terminated polyacrylates suggested by Nakagawa in order to reduce the shrinkage and increase the adhesion of those compositions. (Ans. 9-10.) The difficulty with this position is that the Examiner has not come forward with credible evidence that the reduced shrinkage and the increased adhesive strength resulting in the Poppo compositions would have been expected, reasonably, in the relevant Nakagawa compositions. As Lin points out (Br. 46-47), Poppo describes a Appeal 2010-010391 Application 11/755,159 13 sealant composition that is introduced into a mold that encases the leaking area of a pipe. The sealant is composed of an elastomeric modified acrylic adhesive such as those described by U.S. Patent 3,873,640 to Owston,17 a blowing agent, fillers, plasticizers, and an adhesive-curing catalyst. Gas generated by decomposition of the blowing agent assists the flow of the sealant into the interstices of the pipe. (Poppo col. 1, ll. 59-65.) The filler and plasticizer are said to increase the adhesive strength and flexibility of the cured sealant. (Id. at col. 1, l. 67 to col. 2, l. 2.) The resulting seal is said to be a “dense highly cross-linked solid with numerous macroscopic isolated internal blowholes†that is impervious to moisture and highly resistant to chemicals. (Id. at col. 2, ll. 4-7.) The Examiner does not dispute the composition of the representative adhesive used by Poppo and reproduced in the Brief at page 47. Notably, the Examiner does not cite (Ans. 6) any monomers taught by Nakagawa or suggested in the 278 Specification that correspond to the hydroxyethyl methacrylate capped urethane or the methacrylic acid precursors of the adhesive sealants taught by Poppo. Rather, the Examiner appears to assume that the composition of the Poppo sealant is irrelevant in view of Poppo’s teaching (Poppo, col. 4, ll. 30-33) of addition of polyethylene powder to reduce shrinkage of the cured adhesive (See Ans. 15, 16.) Further, the Examiner appears to assume that that teaching applies directly to the compositions taught by Nakagawa. (Id.) 17 Owston is cited by Poppo at col. 4, l. 21, and was discussed by Lin during prosecution in the response filed 3 November 2008, at pages 21-22. According to Lin, Owston describes adhesive compositions especially suited for binding to polyvinyl chloride. (Br. 47.) Appeal 2010-010391 Application 11/755,159 14 The evidence submitted by Lin, e.g., Petrie, indicates that the performance and properties of sealant and adhesive formulations depend heavily on the base resin materials. (Br. 42; Petrie 464, 469.) Petrie indicates further that a variety of mechanisms can underlie shrinkage. (Petrie, para. bridging 469-70.) This evidence undermines the Examiner’s apparent assumptions that there is a single, universal cause of shrinkage in cross-linked polymeric compositions, and that adding polyethylene particles inevitably prevents or diminishes shrinkage in all compositions. In any event, the Examiner has not come forward with evidence indicating that there is a single, universal cause of shrinkage in cross-linked sealant compositions, or that adding polyethylene particles inevitably prevents or diminishes shrinkage in all sealant compositions. Nor has the Examiner come forward with evidence indicating that, notwithstanding the differences between the compositions described by Nakagawa and those described by Poppo, a person having ordinary skill in the art would have expected the effect of adding polyethylene particles to be substantially the same.18 Bair (applied only against claim 16 in Rejection G) does not cure any of these deficiencies. The Examiner’s failure to cite credible evidence supporting 18 We do not credit Lin’s arguments regarding the alleged resistance of cured urethane sealants to hydrocarbon fluids (Br. 30) because that argument is directly contradicted by the reference on which Lin relies. See, POLYMERIC SYSTEMS, INC., CHEMICAL RESISTANCE OF CURED URETHANE SEALANTS 1 (presented in the Evidence Appendix to the Brief), column 1, listing hydrocarbon solvents, including benzene, Diesel fuel and gasoline, mineral spirits, lacquer- and paint-thinner, toluene, and xylene, that are said to cause softening and swelling on long-term immersion. Although urethane sealants are said to be relatively impervious to lubricating oils, the class of hydrocarbon liquids is far broader than such oils. Appeal 2010-010391 Application 11/755,159 15 these findings is fatal to the rejection. The weight of the evidence on these rejections favors Lin. Accordingly, we REVERSE the rejections based on the combined teachings of Nakagawa and Poppo. We are left with the provisional obviousness-type double patenting rejections (“PODPâ€). Lin’s failure to argue the rejections on the merits waives all such arguments in this appeal. 37 C.F.R. § 41.37(c)(1)(vii). See also, Shinseki v. Sanders, 129 S.Ct. 1696, 1706 (2009) (citations omitted) (“Lower court cases make clear that courts have correlated review of ordinary administrative proceedings to appellate review of civil cases in this respect. . . . [T]he party seeking reversal normally must explain why the erroneous ruling caused harm.â€) Of course, we have first to determine whether the PODP rejections remain facially appropriate. In many cases, a PODP will no longer be in condition for review when the Board considers the case because the claims of the reference will have changed substantially; or the copending application may have been abandoned. That is not the case in this appeal with respect to the 278 and the 287Applications, as none of the claims in either application changed after the final rejections were entered on 29 and 28 January 2009, respectively. Moreover, the USPTO has a long-standing policy, endorsed by the predecessor of the Federal Circuit, of providing Board review of PODP rejections. See, e.g., In re Mott, 539 F.2d 1291 (CCPA 1976) (reversing as improperly final what should have been left as a provisional obviousness- type double patenting rejection), and In re Wetterau, 356 F.2d 556, 558 n.2 (CCPA 1966) (noting the benefits to the applicant and to the PTO of the Appeal 2010-010391 Application 11/755,159 16 PODP rejection practice; the court considered the merits of the PODP on the merits, including evidence of unexpected results). The PTO policy is set out in The Manual of Patent Examining Procedure (“MPEPâ€) § 804 I.B.1 (rev. 5, August 2006). According to this guidance, when there are no other rejections, the earliest filed claims (or those containing the fewest limitations), should be allowed to issue without a terminal disclaimer, while the obviousness-type double patenting rejection should be maintained in the later-filed or more limited application.19 As for “judicial efficiency,†we perceive no efficiency in delaying the determination of the merits of a final rejection by a Primary Examiner that remains substantially unchanged on our consideration. Our decision, whether affirming or reversing the rejection, becomes the final agency determination and is binding on the Examiner unless the claims of either application change in a substantial and material way, or unless the evidentiary basis of the rejection changes substantially and materially. It would serve no useful purpose to leave such an issue “hanging,†and possibly subject to a further appeal without amendment to the claims or the evidentiary record. As described supra, the claims of the 278 Application in the 3601 Appeal require the presence of the shrink-reducing component, but not the amine antioxidant or the sulfonate or phosphonate diluent required 19 We understand the MPEP to provide guidance, not a complete response to all possible situations in which PODP rejections might arise. The proper procedure in each case must be determined on the particular facts and circumstances. Appeal 2010-010391 Application 11/755,159 17 by the 159 Application. Claims 7-12, 15, and 16 of the 287 Application in the 8140 Appeal require both the amine antioxidant and the shrinkage- reducing component. Claims 1-5, 7-14, 16, 18, and 20 of the 159 Application require the presence of a sulfonate diluent plasticizer, and claims 8-13 require the presence of a shrinkage reducing component. As we have determined that the prior art of record does not support the obviousness of adding a sulfonate plasticizer to bis-silyl poly(meth)acrylate compositions suggested by Nakamura, we conclude that the same is true regarding the compositions claimed in the 278 Application and in the 287 Application. We therefore REVERSE the PODP rejections of claim 1 and the cited dependent claims, and claim 20. However, in claim 19 of the 159 Application, the plasticizer may be a phosphonate ester, and Nakagawa suggests phosphonate esters such as tricresyl phosphate [(CH3PhO)3P=O] and tributyl phosphate [(buO)3P=O], which are within the scope of the diluent recited in these claims. Thus, for phosphate esters, the Examiner’s reliance on Sugiyama was harmless.20 Due to the presence of the transitional term “comprising,†claim 19 is open to additional components such as the amine antioxidants recited in the claims of the 287 Application. Accordingly, we AFFIRM the rejection of claim 19 in view of the cited claims of the 287 Application, and also in view of the cited claims of the 278 Application, both in view of the teachings of Nakamura. 20 Cf. Rejections B and E of claim 19, reversed on other grounds. Appeal 2010-010391 Application 11/755,159 18 C. Order We REVERSE the rejection of claims 1, 2, 7, 14, and 18 under 35 U.S.C. § 103(a) in view of the combined teachings of Nakagawa and Sugiyama. We REVERSE the rejection of claim 19 under 35 U.S.C. § 103(a) in view of the combined teachings of Nakagawa and Siggel.
