DISCUSSION The Examiner finds Funk discloses "'a laminate of a metal sheet having thermoplastic material on both sides[lOJ ... producing a suitable material for use as a pipe-wrap' (col. 1, lines 29-32) where the laminate 'uses are in corrosion-resistant areas' (col. 1, lines 60-61)." Final Act. 2. 11 The Examiner finds Funk discloses that "'thermoplastic resins which can be employed to produce the thermoplastic sheets are ... polyvinyl chloride [PVC] ... and polyvinyl fluoride' ( col. 2, lines 30-36)." Final Act. 3. The Examiner finds that this disclosure in Funk "is considered to mean that the outer layer, which is exposed to the environment, may comprise PVC or a fluoropolymer (PVF)." Final Act. 3 ( emphasis added). The Examiner also finds Funk discloses that "'among the synthetic thermoplastic resins which can be employed to produce the thermoplastic sheets are ... chlorinated polyethylene ... [and] polyvinyl chloride' (col. 2, lines 30-35)." Final Act. 4. The Examiner finds that this disclosure in Funk "is considered to mean that the disclosure of Funk encompasses chlorinated polyethylene or polyvinyl chloride as an inner polymeric layer yielding a PVC or PVF/stainless steel/chlorinated polyethylene or polyvinyl chloride structure," whereby the outer and inner layers may comprise the same (i.e., PVC) or different (i.e., PVF and chlorinated polyethylene, respectively) materials. Final Act. 4 ( emphasis added). The Examiner finds Funk does not disclose that "the chlorinated polyethylene or polyvinyl chloride [inner] layer comprises a laminate with 1° Funk Figure 2 depicts laminate 38 comprising upper sheet 20, metal sheet 32, and lower sheet 30. Funk, col. 3, 11. 62---66. 11 Final Office Action dated September 23, 2016. 4 Appeal2017-011001 Application 12/405,708 ethylene acid copolymer resin as recited in the instant claims." Final Act. 4 ( emphasis added). Therefore, the Examiner turns to Kelch. The Examiner finds Kelch discloses "'a coextruded flexible film having a first layer comprising a blend of a vinyl chloride polymer and a chlorinated polyolefin and a second layer comprising a normally solid thermoplastic adhesive."' Final Act. 4 ( citing Kelch, col. 1, 11. 65-68). The Examiner finds Kelch discloses that suitable normally solid thermoplastic adhesives include copolymers of ethylene and a copolymerizable monomer such as acrylic acid. Final Act. 4 ( citing Kelch, col. 4, 11. 20-29). The Examiner concludes that it would have been obvious to one of ordinary skill in the art "to use the vinyl chloride polymer-chlorinated polyolefin blend/ethylene-acrylic acid copolymer laminate of Kelch as the chlorinated polyethylene [inner] layer in the invention of Funk" to obtain the advantages disclosed in Kelch (i.e., long term weather resistance, UV stability, hardness, and scratch resistance). Final Act. 5. The Appellants dispute, inter alia, the Examiner's finding that "one of the upper and lower thermoplastic sheets 20, 30 may be made of a different material or otherwise be formed differently than the other." Br. 7. The Appellants argue: Funk simply lists synthetic thermoplastic resins that can be employed to produce the thermoplastic sheets. No disclosure is made with respect to particular combinations of materials or configurations used in the upper and lower thermoplastic sheets 20, 30. Indeed, Funk refers collectively to the "thermoplastic sheets" in the cited passage at column 2, lines 30-36, without suggesting that one sheet, individually, may be formed of one synthetic thermoplastic material while the other sheet, separately, may be formed from a different synthetic therm op las tic material. 5 Appeal2017-011001 Application 12/405,708 Moreover, Funk[] describes a calendering process to form the laminate 38 that uses chlorinated polyethylene and aluminum "to produce a laminate comprising an aluminum sheet having chlorinated polyethylene on both sides thereof." Column 3, lines 7-10. Funk provides that the process is the same for other materials, such as polyvinyl chloride and stainless steel foil. Column 3, lines 35-36. Thus, with respect to the construction of the laminate 38, Funk discloses that the thermoplastic sheets 20, 30 are the same on both sides of the metal sheet 32. For at least these reasons, Appellant respectfully submits that Funk does not disclose the outer polymeric layer film and inner polymeric layer in the manner claimed. Br. 7-8. The Appellants argument is persuasive of reversible error. Funk discloses: Included among the synthetic thermoplastic resins which can be employed to produce the thermoplastic sheets [20, 30] are those which are disclosed in [the prior art], such as chlorinated polyethylene, chloro-sulfonated polyethylene, polyvinyl chloride, polychloroprene, polyisobutylene, and polyvinyl fluoride. The preferred thermoplastic materials are an elastomeric chlorinated linear polyethylene and polyvinyl chloride. Funk, col. 2, 11. 30-38. To establish a prima facie case of unpatentability in a prior art rejection, an Examiner must demonstrate that the claimed invention is anticipated 12 and/or rendered obvious by the prior art. See In re Oetiker, 977 12 "To anticipate a claim, a prior art reference must disclose every limitation of the claimed invention, either explicitly or inherently." In re Schreiber, 128 F.3d 1473, 1477 (Fed. Cir. 1997). Inherency may not be established by probabilities or possibilities, but rather must be inevitable. In re Oelrich, 666 F.2d 578, 581 (CCPA 1981). 6 Appeal2017-011001 Application 12/405,708 F.2d 1443, 1445 (Fed. Cir. 1992) (examiner bears initial burden of presenting a prima facie case of unpatentability). In this case, the Examiner does not conclude that it would have been obvious to one of ordinary skill in the art to select different thermoplastic resins for upper and lower thermoplastic sheets 20, 30 based on the teachings in Funk. See Ans. 14 ( explaining that a conclusion of obviousness for the selection of different thermoplastic materials for resin layers 20 and 30 "is neither made in the rejection of record or necessary"). 13 Rather, using the broadest reasonable interpretation standard, the Examiner finds that "one of ordinary skill in the art ... would choose a specific resin for each layer, including different resins, for the inner and outer layer [based on Funk's disclosure]." Ans. 14. The broadest reasonable interpretation standard is reserved for claim construction. See, e.g., In re Herz, 537 F.2d 549, 551 (CCPA 1976) ("claims are given their broadest reasonable construction consistent with the specification"). To the extent the Examiner is referring to the broadest reasonable interpretation standard to support a finding that Funk describes, either expressly or inherently, that the thermoplastic resin comprising upper and lower thermoplastic sheets 20, 30 may be different from one another, the Examiner's interpretation of Funk is not supported by the record on appeal. We recognize that Funk does not expressly disclose that the upper and lower sheets 20, 30 must be comprised of the same thermoplastic resin. Nonetheless, the Examiner does not direct us to any portion of Funk expressly disclosing that the upper and lower sheets, in certain 13 Examiner's Answer dated June 15, 2017. 7 Appeal2017-011001 Application 12/405,708 embodiments, may comprise different thermoplastic resins in a single laminate. Thus, to establish that claim 1 is unpatentable, the Examiner must show that the upper and lower sheets of a single laminate in Funk inherently comprise different thermoplastic resins. Funk's entire disclosure describes embodiments wherein the upper and lower sheets are comprised of the same thermoplastic resin( s ). More specifically, Funk discloses that an object of the invention is "to provide a process for producing a laminate of a metal sheet having thermoplastic material on both sides thereof formed in a single pass through a calender." Funk, col. 1, 11. 28-31. Funk discloses a calendering process using chlorinated polyethylene and aluminum to produce a laminate comprising an aluminum sheet having chlorinated polyethylene on both sides thereof. Funk, col. 3, 11. 7-10. Funk discloses that: The aluminum sheet is fed into the nip between the second roll and the third roll while contacting at 250° to 350° F. the upper chlorinated polyethylene sheet with the top of the aluminum sheet and while simultaneously contacting the lower chlorinated polyethylene sheet with the bottom of the aluminum sheet. The temperature of the chlorinated polyethylene sheet may be from 300° to 400° F. when the thermoplastic material contains polyvinyl chloride. The top and the bottom of the aluminum sheet have thereon a coating of a copolymer of 10 to 20 percent by weight of vinyl acetate, the balance of the copolymer being essentially vinyl chloride. Funk, col. 3, 11. 18-30 (emphasis added); see also Funk, col. 3, 11. 35- 36 ( disclosing that the process is the same for polyvinyl chloride and stainless steel foil). Moreover, in Funk's examples, the same thermoplastic material is contacted on the top and bottom surfaces of a metal sheet. Funk, col. 6, 11. 8 Appeal2017-011001 Application 12/405,708 52-68; see also Funk, col. 5, 11. 48-52 ( disclosing that the examples "represent the best mode contemplated for practicing the present invention"). The Examiner finds that the specific embodiments disclosed in Funk are "not considered limiting when evaluating the broader disclosure, which recites thermoplastic resins and allows the ordinary artisan to select the specific resins from a disclosed list in the reference." Ans. 14 (emphasis added). The Examiner, however, does not explain why Funk's "broader disclosure" teaches that the upper and lower sheets may comprise different thermoplastic resins. The fact that one of ordinary skill in the art could have selected different resins, without more, does not establish that Funk teaches, either expressly or inherently, that the resins may be different. In sum, a preponderance of the evidence does not support the Examiner's finding that one of ordinary skill in the art would have selected different thermoplastic resins for the upper and lower sheets of a single laminate based on Funk's disclosure. Therefore, the obviousness rejection of independent claim 1 and dependent claims 5, 6, and 12-20 is not sustained. The Examiner does not rely on Parker to cure the deficiencies in the obviousness rejection of claim 1. See Final Act. 12 (finding that Parker discloses an adhesive coating comprising a composition such as a silicone resin or an acrylic polymer). Therefore, the obviousness rejection of claims 8-11 also is not sustained. C. DECISION The Examiner's decision is reversed. REVERSED 9 Copy with citationCopy as parenthetical citation
