Introduction1 Jim Ibarra, Rick Wallace, Barry L. Marginean, Joel D. Neri, Pamela A. Geddes, Barry J. Briggs, and Daniel J. Harrison (“Ibarra”) timely appeal under 35 U.S.C. § 134(a) from the final rejection2 of claims 5, 7, 8, and 12.3 We have jurisdiction under 35 U.S.C. § 6. We AFFIRM. The subject matter on appeal relates to a system for transferring digital decal images from a paper support to a ceramic substrate and thermally fixing the transferred images. Prior art wet and dry decal printing processes are said to be difficult to adapt to digital decal printing processes due to problems including excessively high transfer temperatures that result in surface imperfections (bubbles, cracks, voids, etc.), low color density, and poor durability. (Spec. 1-3.) The claimed invention involves, inter alia, a thermal transfer ribbon having a support and a ceramic ink layer present in a coating comprising a solid carbonaceous binder, and at least one of a film- forming glass frit, an opacifying agent, and a colorant. (Spec. 3, ll. 11-25.) Claim 5, reproduced on the following page, is representative. 1 Application 11/071,015, Thermal Transfer Assembly for Ceramic Imaging, filed 3 March 2005, as a continuation of application 10/621,976, filed 17 July 2003, which is now U.S. Patent 6,990,904. The benefit of a series of four successive continuations-in-part is claimed back to 31 October 2000. The specification is referred to as the “015 Specification,” and is cited as “Spec.” The real party in interest is listed as International Imaging Materials, Inc. (Corrected Appeal Brief, filed 11 April 2008 (“Br.”), 3.) 2 Office action mailed 14 September 2007 (“Final Rejection”; cited as “FR”). 3 Claims 2, 4, 14, 16, and 24 have been withdrawn from consideration (FR 1, ¶ 4a) and are not before us. 2 Appeal 2009-002512 Application 11/071,015 5. A system for forming a digitally printed image in a glass substrate, said system comprising: (a) a glass substrate and a glass substrate conveyor; (b) a glass substrate washer for washing said glass substrate, thus producing a washed glass substrate; (c) an image transfer medium comprising a flexible support consisting essentially of paper, a transferable polymeric cover-coating releasably bound to said flexible support, and a digitally printed image formed on said polymeric cover- coating, wherein said image transfer medium is further comprised of opacification particles with a refractive index of at least 2.0 and a release layer operatively configured to promote separation and removal of said flexible support from said imaged polymeric cover-coating, and wherein: 1. said polymeric cover-coating can be separated from said flexible support with a peel force of less than about 30 grams per centimeter at a temperature of 20 degrees Celsius, 2. said release layer is contiguous with said flexible support, 3. said release layer has a surface energy of less than about 40 dynes per centimeter and a Sheffield smoothness of from about 1 to about 50 Sheffield units, and 4. said release layer is comprised of a thermoplastic polymer that softens at a temperature of from about 60 to about 150 degrees Centigrade; (d) a heat treater for removing said polymeric cover-coating and for fusing said digitally printed image to the surface of said glass substrate thus producing a fused digitally printed image and glass substrate; and (e) a quencher for cooling said fused digitally printed image and glass substrate. (Claims App., Br. 27-28; indentation, paragraphing, and emphasis added.) 3 Appeal 2009-002512 Application 11/071,015 The Examiner has maintained the following ground of rejection:4 Claims 5, 7, 8, and 12 stand rejected under 35 U.S.C. § 103(a) in view of the combined teachings of Pearson,5 Parker,6 Newton,7 and Seymour.8 Ibarra contends, inter alia, that the Examiner erred in concluding that it would have been obvious to substitute the polyethylene non-wax release layer 5 that separates paper substrate 10 from lacquer transfer coating 20, which bears ink design 30 taught by Parker for the release agent 305 in the decal carrier 302 taught by Pearson.9 According to Ibarra, such a substitution, to meet the claim limitation that the “release layer is contiguous with said flexible support,” would require elimination of prime coating layer 304 (App. Br. 15-16), which Pearson provides to render the paper layer 303 “less porous and substantially impervious to the heat release agent.” (Pearson, p. 13, first full para.) Ibarra argues that layer 304 is essential to the principles of operation of Pearson’s invention, and that the Examiner’s rejection is thus fatally flawed. (App. Br. 15-16.) Moreover, 4 Examiner’s Answer mailed 13 May 2008. (“Ans.”). 5 David Pearson, Glass Treatment Process and Apparatus, WO 98/43832 (1998). 6 Tim Parker et al., Heat Transferable Laminate, U.S. Patent 4,927,709 (1990). 7 Gerald W. Newton and Vincent J. Cahill, Digital Thermal Printing Process, U.S. Patent 6,504,559 B1 (7 January 2003), based on an application filed 14 September 1998. 8 Raymond B. Seymour & Charles E. Carraher, Jr., Polymer Chemistry, an Introduction, 380 (3d ed. 1992). 9 For clarity, reference labels are presented in bold font regardless of their presentation in the original document. 4 Appeal 2009-002512 Application 11/071,015 according to Ibarra, there would have been no reason to use the polyethylene release layer taught by Parker because none of the wax-halo or scuffing problems Parker seeks to solve for decals adhered to plastic substrates at relatively low temperatures apply to the decals transferred to glass substrates at very high temperatures, as taught by Pearson. (App. Br. 18-20.) The Examiner responds that the term the term “contiguous” includes the sense of being “in close proximity without actually touching or near” in its meaning. (Ans. 8.) Based on this interpretation, the Examiner concludes that the term “contiguous” permits an intervening thin layer between the release layer and the paper, as long as the two outer layers remain close to one another. (Id. at 9). Moreover, according to the Examiner, the term “flexible support consisting essentially of paper” [claim 1, part (c)] includes materials that do not change the basic and novel characteristic of the support, which is, the Examiner argues, that the support is flexible. (Id.) Accordingly, the Examiner finds that the “flexible support” reads on paper 303 together with prime coating layer 304. (Id. at 9.) Finally, the Examiner argues, one skilled in the art would have recognized that, because Parker does not require a prime coating layer, one could replace Pearson’s wax release layer with the polyethylene layer and not use Pearson’s prime coating layer. (Id. at 10.) The issues dispositive of this appeal are thus: (1) are the Examiner’s interpretations of the claim limitations correct? alternatively, 5 Appeal 2009-002512 Application 11/071,015 (2) has Ibarra proven error in the Examiner’s determination that there would have been adequate motivation to substitute Pearson’s wax release layer and prime coating layer with Parker’s polyethylene release layer? B. Findings of Fact Findings of fact throughout this Opinion are supported by a preponderance of the evidence of record. The 015 Specification 1. The features of the claimed system most relevant to this appeal are illustrated in Figure 30, which is reproduced below: {Figure 30 shows a decal partially transferred to a substrate} 2. The layers and components of the layers shown in Figure 30 are described with respect to embodiments illustrated in other figures. 6 Appeal 2009-002512 Application 11/071,015 3. As shown in Figure 30, a decal transfer assembly comprises an ink image layer 222 that is supported by transferable overcoat 242. 4. Ink image layer 222 contains a solid, volatile, carbonaceous binder (cf. Spec. 32, ll. 12-29, describing the “frosting ink layer” 202 shown in Figure 12) and a glass-forming “frit,” and opacifying agents (id. at l. 30, to 33, l. 32). 5. The 015 Specification explains that the volatile carbonaceous binders are made from polymers such as polyvinylbutyral, ethyl cellulose, or polymethylmethacrylate (Spec. 38, ll. 1-4), which are said to be transformed into gases at temperatures greater than 500°C, leaving a residue of less than about 5 weight percent of the original binder. (Id. at ll. 20-26.) 6. Transferable covercoat 242 lies on wax release layer 36, which in turn lies on flexible paper support 226. 7. Pressure sensitive adhesive layer 412 overlies the decal assembly to permit adhesive transfer of the decal to a glass or ceramic substrate 12. 8. On raising the temperature from about 60°C to about 150°C, depending on the wax release layer (Spec. 23, l. 5-7), the wax release layer 36 softens so the decal can be separated from the paper support 226 and adhesively transferred to the glass substrate 12. 9. According to the 015 Specification, the substrate bearing the transferred decal is placed in a kiln at 621°C for 10 minutes to burn away the binder and leave a mixture of film-forming glass frit, opacifying agents, and ink on the substrate. (Spec. 73, ll. 21-27.) 7 Appeal 2009-002512 Application 11/071,015 Pearson 10. Pearson describes a system in which glass substrates are washed (Pearson, p. 16, first line), conveyed to a station where decals are heat- transferred from paper carriers to the glass substrates (id., 2d para.), then transferred to an oven in which the decals are fused to the substrate at still higher temperatures (id., 3d para.), tempered (id. at 19, first full para.) and finally quenched (id. at 20, first para.). 11. The decals 301 are carried on a decal carrier 302, as shown in Figure 3, which is reproduced below: {Figure 3 is said to show a decal and decal carrier} 12. Decal carrier 301 comprises a bottom paper layer 303, a prime coating, or barrier layer 304, and a layer 305 of heat release agent. (Pearson, p. 13, first full para.) 13. Barrier layer 304 is said to render paper layer 303 “less porous and substantially impervious to the heat release agent,” resulting in a “more smooth and uniform heat release agent layer.” (Pearson, p. 13, first full para.) 8 Appeal 2009-002512 Application 11/071,015 14. The barrier layer may be a seal coating of starch casein, glue, alkali metal silicate, water glass, or other alkali metal silicates with a dispersed filler. (Pearson, p. 13, first full para.) 15. The heat release agent is described as being a relatively high melting point wax that has only slight solubility and resists penetration by petroleum hydrocarbons. (Pearson, p. 13, 2d full para.) 16. Waxes such as polyethylene glycol having a softening point in the approximate range of 65-180°C are said to be preferred. (Pearson, p. 13, 2d full para.) 17. Pearson does not describe the heat release agent 305 as being in direct contact with the paper layer 303, the numerical physical properties recited in claim 5, or digitally printing the image on the cover coating. Parker 18. Parker describes a heat transferable laminate 7, illustrated in Figure 1, reproduced below, {Figure 1 is said to show a heat transferable laminate} as comprising transferable substrate 15, which is separated from carrier substrate 10 by release layer 5. 9 Appeal 2009-002512 Application 11/071,015 19. The transferable substrate 15 comprises lacquer transfer coating 20, which is covered by ink design layer 30, which in turn is covered by adhesive layer 40. (Parker, col. 5, ll. 35-39.) 20. Substrate 15 can be applied to articles such as a plastic bottle (Parker, Abstract, and col. 3, ll. 16-20) using a platen having a surface temperature between about 275°F and 425°F (135 to about 218°C) to soften the release layer 5. (Parker, col. 5, ll. 50-55.) 21. The release system comprising release layer 5 is described as a polyethylene or equivalent ethylene copolymer (Parker, col. 4, ll. 27-37), rather than a wax. 22. According to Parker, it was considered “surprising” that “[c]lean separation of the transfer coating 20 from the polyethylene layer 5 is achieved without leaving any discernible portion of either layer on the other when the heated platen or heated platen roller temperature is in the range between about 275°F. to 425°F.” (Parker, col. 7, ll. 32-36.) 23. Parker teaches further that it is preferable to use clay-coated paper for sheet 10 “to provide[] a proper smooth barrier coating to prevent the polyethylene release layer 5 from being drawn into the paper” and to provide “a smooth polyethylene surface during the heat transfer process.” (Parker, col. 8, ll. 51-61.) C. Discussion As the Appellant, Ibarra bears the procedural burden of showing harmful error in the Examiner’s rejections. See, e.g., In re Kahn, 441 F.3d 10 Appeal 2009-002512 Application 11/071,015 977, 985-86 (Fed. Cir. 2006) (“On appeal to the Board, an applicant can overcome a rejection [under § 103] by showing insufficient evidence of prima facie obviousness”) (citation and internal quote omitted). Arguments not timely raised have been waived. 37 C.F.R. § 41.37(c)(1)(vii) (2009), second sentence. Initially, we note that all of the references on which the Examiner relies are indisputably prior art with respect to Ibarra’s claimed subject matter. Concerns (FR 6, item 8; Br. 13) regarding whether David Pearson would or would not have considered—or have been able to consider—the teachings of Parker are not ordinarily relevant to the obviousness inquiry. That inquiry is conducted from the standpoint of a hypothetical person of ordinary skill in the relevant arts at the time the invention was made, i.e., as of the filing date of the application under consideration. Substantively, Ibarra has not disputed the Examiner’s treatment of any limitations other than the limitations recited in claim 5 relating to the release coating. Accordingly, all claims stand or fall with claim 5. We begin by considering the Examiner’s claim interpretation. Although the Examiner cites a definition of the word “contiguous” that includes a sense of separation between two things described as being contiguous, the Examiner has not come forward with any credible evidence from the 015 Specification indicating that a person having ordinary skill in the art would have understood that disclosure to have used the term “contiguous” in a sense broader than the definitions that include “touching,” or “in contact with,” provided in, e.g., Webster’s Third New International Dictionary (1993) (“Webster”). Indeed, Webster quotes a line attributed to 11 Appeal 2009-002512 Application 11/071,015 the poet William Wordsworth as an example of the broad meaning proposed by the Examiner. Our reviewing court has explained that “[i]t is well established that dictionary definitions must give way to the meaning imparted by the specification.” In re Johnston, 435 F.3d 1381, 1384 (Fed. Cir. 2006). As there appears to be no support in the 015 Specification for the Examiner’s broad reading, we reject that proposed interpretation. The Examiner’s interpretation of the term “flexible substrate consisting essentially of paper” as permitting the inclusion of coated papers is similarly dissociated from the use of that term in the 015 Specification. The 015 Specification describes the flexible support generally at page 20, and describes several coated papers, e.g., at pages 26-27. But the Examiner has not provided any analysis demonstrating why any of the uses of the term indicate that a paper together with a non-paper coating is properly described as “consisting essentially of paper” in the context of the claims and the supporting disclosure. Nor is such a use facially apparent in the 015 disclosure. The Examiner’s substantive argument, however, stands differently. The Examiner argues that the artisan “would appreciate [that] the use of Parker et al[.]’s polyethylene release layer in Pearson’s apparatus would not require the use of the barrier layer since Parker et al[.] does not require it.” (Ans. 10.) The evidence of record shows that the polyethylene release layer taught by Parker performs the release functions of the wax layer 305 taught by Pearson. Although the Examiner’s finding that Parker does not require a barrier coating on the paper might be quibbled, given Parker’s recommendation that a clay coating be used as a barrier coating (Parker, 12 Appeal 2009-002512 Application 11/071,015 col. 8, ll. 51-64), we cannot say this error is harmful. The polyethylene release coating provided by Parker functions in the same way as the release coating provided by Pearson, and both Parker and Pearson make provisions to protect, as necessary, the paper carrier layer from invasion by the release layer. The substitution of functionally equivalent materials and structures to perform the intended functions is a classical instance of prima facie obviousness. Far from destroying the “principles of operation” of Pearson, the Examiner’s rejection observes and respects them. Ibarra argues further that a person having ordinary skill in the art would not have been motivated to consider the polyethylene release layers taught by Parker because Parker is not concerned with a high temperature fixing process that removes the carbonaceous binders. (Br. 17-25.) These arguments are not persuasive of harmful error because, for the reasons given supra, a person having ordinary skill in the art would have considered Parker for its teachings regarding the low-temperature thermal release function of the polyethylene layer. Persons having ordinary skill in the art would not have considered using the entire decal described by Parker in an inappropriate situation. Moreover, to the extent that such persons would have considered the binders taught by Parker in the decal, he or she would have noted the use of polyethylmethacrylate as the primary binder and cellulose derivatives in Formulation D as the secondary binder resins. (Parker, col. 12, Table II.) These are the same types of binder resins as those suggested by Pearson for high-temperature ceramics printing. (Pearson, p. 14, last para.). Thus, Parker provides the solutions to the compatibility problems alleged by Ibarra. (Br. 25.) 13 Appeal 2009-002512 Application 11/071,015 D. Order We AFFIRM the rejection of claims 5, 7, 8, and 12 under 35 U.S.C. § 103(a) in view of the combined teachings of Pearson, Parker, Newton, and Seymour. 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 ssl HOWARD J.
