DECISION ON APPEAL Appellant1 requests our review under 35 U.S.C. § 134(a) of the Examiner’s final rejection of claims 6–12.2 We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM IN PART and enter a NEW GROUND OF REJECTION pursuant to 37 C.F.R. § 41.50(b). 1 We use the word “Appellant” to refer to the “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies BASF SE as the real party in interest. Appeal Brief filed May 29, 2019 (“Appeal Br.”) at 3. 2 Final Office Action entered October 5, 2018 (“Final Act.”) at 1. Appeal 2020-000501 Application 14/780,569 2 CLAIMED SUBJECT MATTER Appellant claims a method of forming a shaped article (independent claim 6) and a shaped article (independent claim 9). Appeal Br. 7–8. Independent claims 6 and 9 illustrate the subject matter on appeal, and read as follows: 6. A method of forming a shaped article of a composition consisting of i) a polyalkylene terephthalate, ii) a (polyalkylene isophthalate)-co-(polyalkylene terephthalate), iii) a polyalkylene terephthalate-reinforcing fiber, and iv) optionally, one or more additives selected from the group consisting of lubricants, thermal antioxidants, nucleating agents, pigments, and combinations thereof, wherein the alkylene in component i) is selected from the group consisting of a methylene group, ethylene group, propylene group, butylene group, and cyclohexene dimethylene group, the alkylene in component ii) is selected from the group consisting of methylene, ethylene, propylene, and butylene, and the composition has a melting point in a range from 182°C to 220°C, the method comprising: melt-forming the composition together with one or more additional thermoplastic materials to form the shaped article, wherein at least one of the additional thermoplastic materials is polyvinyl chloride, and wherein the shaped article has a composite structure between (i) the composition and (ii) the one or more additional thermoplastic materials. 9. A shaped article comprising: (a) a composition consisting of i) a polyalkylene terephthalate, ii) a (polyalkylene isophthalate)-co-(polyalkylene terephthalate), iii) a polyalkylene terephthalate-reinforcing fiber, and Appeal 2020-000501 Application 14/780,569 3 iv) optionally, one or more additives selected from the group consisting of lubricants, thermal antioxidants, nucleating agents, pigments, and combinations thereof, wherein the alkylene in component i) is selected from the group consisting of methylene group, ethylene group, propylene group, butylene group, and cyclohexene dimethylene group, the alkylene in component ii) is selected from the group consisting of methylene, ethylene, propylene, and butylene, and the composition has a melting point in a range from 182°C to 220°C; and (b) one or more additional thermoplastic materials, wherein at least one of the additional thermoplastic materials is polyvinyl chloride; wherein the shaped article has a composite structure between (i) the composition and (ii) the one or more additional thermoplastic materials. Appeal Br. 24–25 (Claims Appendix) (emphasis and spacing added). REJECTION The Examiner maintains the rejection of claims 6–123 under 35 U.S.C. § 103 as unpatentable over Aluplast4 (EP 2431152 A2, published 3 Although the heading for this rejection lists claims 6–10 as rejected under 35 U.S.C. § 103, the body of the rejection refers to claims 6–12. We, therefore, treat the listing of claims 6–10 in the heading as an inadvertent typographical error. 4 The Examiner cites numerous paragraphs of “Aluplast” in the Final Action. Final Act. 2. This patent application was published in German, however, and a full-length English translation of the application is not of record. Appellant did submit a copy of the Aluplast application with an Information Disclosure Statement filed September 28, 2015, but the copy submitted by Appellant included only an English abstract, with the remainder of the application being in German. The particular document cited by the Examiner in the Final Action that forms the basis of the Examiner’s rejection, therefore, is not apparent on the record before us. Appellant indicates in the Appeal Brief that Appellant’s citations to Aluplast “are based on the English machine translation of Aluplast available from the Appeal 2020-000501 Application 14/780,569 4 March 21, 2012) in view of Uno (US 6,660,789 B2, issued December 9, 2003) and Wust et al. (US 2010/0319843 Al, published December 23, 2010)5 in the Answer entered August 12, 2019 (“Ans.”). FACTUAL FINDINGS AND ANALYSIS Upon consideration of the evidence relied upon in this appeal and each of Appellant’s contentions, we affirm the Examiner’s rejection of claims 9–12 under 35 U.S.C. § 103, but designate our affirmance as including new grounds of rejection, for the reasons discussed below. We reverse the Examiner’s rejection of claims 6–8 under 35 U.S.C. § 103 for reasons set forth in the Appeal and Reply Briefs, and below. We review appealed rejections for reversible error based on the arguments and evidence the Appellant provides for each issue the Appellant identifies. 37 C.F.R. § 41.37(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”)). European Patent Office.” Appeal Br. 9, Fn. 1. We, therefore, also refer in this decision to the English machine translation of Aluplast available from the European Patent Office. In the event of further prosecution of this application, however, we advise the Examiner to make of record the Aluplast document relied upon by the Examiner in the Final Action. 5 Although the heading for this rejection does not list Wust as an applied prior art reference (Final Act. 2), the body of the rejection discusses Wust as if it were being applied as prior art (Final Act. 3), which Appellant acknowledges. Appeal Br. 9, Fn. 2. We, therefore, treat the omission of Wust from the heading as an inadvertent typographical error. Appeal 2020-000501 Application 14/780,569 5 Appellant argues claims 6–12 as a group. Appeal Br. 9–23. We, however, address independent claim 6 and its dependent claims 7 and 8 separately from independent claim 9 and its dependent claims 10–12, due to the differing nature of claims 6 and 9, discussed below. Claims 9–12 As discussed above, Appellant does not separately argue any of the pending claims. Appeal Br. 9–23. We, therefore, select independent claim 9 as representative of claims 9–12, and decide the appeal as to claims 9–12 based on claim 9 alone. 37 C.F.R. § 41.37(c)(1)(iv). Independent claim 9 recites, in part, a shaped article comprising (a) a composition consisting of i) a polyalkylene terephthalate, ii) a (polyalkylene isophthalate)-co-(polyalkylene terephthalate), and iii) a reinforcing fiber, and (b) one or more additional thermoplastic materials, at least one of which is polyvinyl chloride. Aluplast discloses co-extrusion molding a first thermoplastic material and a second (reinforcing) plastic material to produce a plastic profile (shaped article). Aluplast p. 1, ll. 10–15; Abst. Aluplast discloses that the first thermoplastic material can be polyvinyl chloride, and the second (reinforcing) plastic material can be polybutylene terephthalate, polyethylene terephthalate, or mixtures thereof. Aluplast p. 4, ll. 128–133; p. 8, ll. 320–321; Abst. Aluplast discloses that the polyvinyl chloride, polybutylene terephthalate, and polyethylene terephthalate are each preferably fiber-reinforced. Aluplast p. 8, ll. 312–313. The Examiner finds that “Aluplast is silent with regard to the composition comprising a (polyalkylene isophthalate)-co-(polyalkylene terephthalate),” and the Examiner relies on Uno for suggesting use of such a Appeal 2020-000501 Application 14/780,569 6 copolymer in combination with polybutylene terephthalate as Aluplast’s second plastic material. Final Act. 2–3. Uno discloses a thermoplastic resin composition having excellent alkali resistance that comprises (A) a polybutylene terephthalate resin containing polybutylene terephthalate/isophthalate copolymer, (B) a polycarbonate resin, (C) an elastomer, and (D) a fibrous reinforcing material. Uno col. 2, ll. 5–13, 38–55. Uno discloses that the polybutylene terephthalate resin may be a mixture of a polybutylene terephthalate resin and a polybutylene terephthalate/isophthalate copolymer, or may be the polybutylene terephthalate/isophthalate copolymer alone. Uno col. 3, ll. 48– 52. Uno discloses that the resin composition may be molded by known methods of molding thermoplastic resins, such as extrusion molding. Uno col. 7, ll. 18–22. In view of these disclosures in Uno, the Examiner concludes that “it would have been obvious to one of ordinary skill in the art . . . to utilize the blend of polybutylene terephthalate and (polyalkylene isophthalate)-co- (polyalkylene terephthalate) of Uno as the reinforcing composition of Aluplast motivated by the expectation of forming an article that has enhanced alkali resistance.” Final Act. 3. Appellant argues that Uno teaches that all four components of Uno’s thermoplastic resin composition are essential for achieving improved alkaline resistance. Appeal Br. 12–15, 17–22 (citing Uno col. 2, ll. 5–14; col. 3, ll. 11–16, 37–47; col. 4, ll. 37–43; col. 4, l. 64–col. 5, l. 3; cols. 7–13 (Tables 1–3)). Appellant argues that, consequently, in order to impart enhanced alkali resistance to Aluplast’s composition, a “skilled artisan must use Uno’s composition including polybutylene terephthalate resin, Appeal 2020-000501 Application 14/780,569 7 polycarbonate resin, elastomer, and fibrous reinforcing material as the reinforcing composition that is coextruded with PVC in Aluplast’s method.” Appeal Br. 14. Appellant argues that, however, “the polycarbonate resin and elastomer components are excluded by the closed ‘consisting of’ transition from the recited composition,” and “the skilled artisan would not have a reasonable expectation of success in achieving improved alkaline resistance without the polycarbonate resin and elastomer materials.” Appeal Br. 12–15 (citing KSR, 550 U.S. 398, 416 (2007); In re Merck & Co., Inc., 800 F.2d 800 F.2d 1091, 1097 (Fed. Cir. 1986)). Appellant argues that “the skilled artisan following the teachings of Uno to improve Aluplast would be led in a direction divergent from the path that was taken by the appellant” because “the skilled artisan would have included the polycarbonate resin and elastomer components from Uno in hopes of obtaining the improved alkali resistance in the modified composition of Aluplast,” and “[t]his divergent path constitutes a teaching away and precludes a prima facie conclusion of obviousness.” Appeal Br. 12–13, 15 (citing In re Kahn, 441 F.3d 977, 990 (Fed. Cir. 2006)). Appellant’s arguments do not identify reversible error in the Examiner’s rejection, however, for reasons that follow. A “comprising” transitional phrase between the preamble and body of a claim opens the claim to inclusion of unrecited materials or components. Gillette Co. v. Energizer Holdings, Inc. 405 F.3d 1367, 1371–1372 (Fed. Cir. 2005) (“The word ‘comprising’ transitioning from the preamble to the body signals that the entire claim is presumptively open-ended.”); In re Baxter, 656 F.2d 679, 686–87 (CCPA 1981) (“As long as one of the monomers in the reaction is [the claimed] propylene, any other monomer Appeal 2020-000501 Application 14/780,569 8 may be present, because the term ‘comprises’ permits the inclusion of other steps, elements, or materials.”). Use of “consisting of” within the body of a claim, rather than immediately following the preamble, closes only the element preceded by “consisting of,” and does not negate the open nature of a “comprising” transition present in the claim between the preamble and body. Mannesmann Demag Corp. v. Engineered Metal Prods. Co., 793 F.2d 1279, 1282 (Fed. Cir. 1986) (confirming that the phrase “consisting of” appearing in a clause of a claim specifically limits only the element set forth in that clause); In re Crish, 393 F.3d 1253, 1257 (Fed. Cir. 2004) (“Crish’s principal argument here that the claims also contain the closed-ended transition term ‘consists,’ and that that term narrows the entire claim, is unpersuasive. The reasonable interpretation of the claims containing both of the terms ‘comprising’ and ‘consists’ is that the term ‘consists’ limits the ‘said portion’ language to the subsequently recited numbered nucleotides, but the earlier term ‘comprising’ means that the claim can include that portion plus other nucleotides.”). In the present case, the recitation of “consisting of” within the body of claim 9 limits the components included in composition (a) to only the explicitly recited components i), ii), iii), and iv). Like the situation in Crish set forth above, however, the “consisting of” phrase in the body of claim 9 does not negate the open nature of the claim imparted by the “comprising” transition that immediately follows the preamble. Crish, 393 F.3d at 1257. Interpreting “consisting of” recited in the body of claim 9 as closing the claim to inclusion of unrecited materials would effectively change the “comprising” transition following the preamble of claim 9 to a “consisting Appeal 2020-000501 Application 14/780,569 9 of” transition, contrary to the principles of Mannesmann and Crish set forth above. Consequently, although the “consisting of” transition recited in the body of claim 9 requires inclusion of only the explicitly recited materials in composition (a), the “comprising” transition that immediately follows the preamble of claim 9 opens the claim to inclusion of unrecited materials in the claimed article. Claim 9, therefore, does not exclude unrecited materials from being included in the claimed article in combination with composition (a) and one or more additional thermoplastic materials (b) at least one of which is polyvinyl chloride; consequently, claim 9 does not exclude the polycarbonate resin and elastomer disclosed in Uno. Because Appellant’s arguments are all premised on the incorrect assertion that claim 9 excludes Uno’s polycarbonate resin and elastomer, Appellant’s arguments do not identify reversible error in the Examiner’s rejection, which we accordingly sustain. We designate our affirmance as including new grounds of rejection, however, because our reasons for affirmance differ materially from those expressed by the Examiner (Final Act. 2–4). In re Leithem, 661 F.3d 1316, 1319 (Fed. Cir. 2011) (“Mere reliance on the same statutory basis and the same prior art references, alone, is insufficient to avoid making a new ground of rejection where the Board relies on new facts and rationales not previously raised to the applicant by the examiner.”). Claims 6–8 Independent claim 6 recites, in part, a method of forming a shaped article of a composition consisting of i) a polyalkylene terephthalate, ii) a (polyalkylene isophthalate)-co-(polyalkylene terephthalate), Appeal 2020-000501 Application 14/780,569 10 iii) a reinforcing fiber, and iv) optionally, one or more additives selected from the group consisting of lubricants, thermal antioxidants, nucleating agents, pigments, and combinations thereof, comprising melt-forming the composition together with one or more additional thermoplastic materials, at least one of which is polyvinyl chloride. Although claim 6 does not exclude additional unrecited method steps due to the “comprising” transition that separates the preamble from the body of the claim, claim 6 nonetheless requires the claimed method to include the step of melt-forming a composition that includes only components i), ii), iii), and iv) together with one or more additional thermoplastic materials, at least one of which is polyvinyl chloride. As discussed above, Aluplast discloses co-extrusion molding fiber- reinforced polyvinyl chloride and a second (reinforcing) plastic material, such as fiber-reinforced polybutylene terephthalate, polyethylene terephthalate, or mixtures thereof, and Uno discloses a thermoplastic resin composition having excellent alkali resistance that comprises (A) a mixture of a polybutylene terephthalate resin and a polybutylene terephthalate/ isophthalate copolymer, (B) a polycarbonate resin, (C) an elastomer, and (D) a fibrous reinforcing material. Aluplast p. 1, ll. 10–15, p. 4, ll. 128–133, p. 8, ll. 312–313, 320–321, Abst; Uno col. 2, ll. 5–13, 38–55. As also discussed above, the Examiner determines that “it would have been obvious to one of ordinary skill in the art . . . to utilize the blend of polybutylene terephthalate and (polyalkylene isophthalate)-co- (polyalkylene terephthalate) of Uno as the reinforcing composition of Aluplast motivated by the expectation of forming an article that has enhanced alkali resistance.” Final Act. 3. Appeal 2020-000501 Application 14/780,569 11 On the record before us, however, the Examiner does not establish that one of ordinary skill in the art reasonably would have utilized Uno’s mixture of polybutylene terephthalate and (polyalkylene isophthalate)-co- (polyalkylene terephthalate) as the second (reinforcing) plastic material in Aluplast’s composition to enhance the alkali resistance of Aluplast’s composition without also including the polycarbonate resin and elastomer components of Uno’s composition in Aluplast’s composition, for reasons expressed by Appellant and discussed below. As discussed above, Appellant argues that Uno teaches that all four components of Uno’s thermoplastic resin composition are essential for achieving improved alkaline resistance. Appeal Br. 12–15, 17–22 (citing Uno col. 2, ll. 5–14; col. 3, ll. 11–16, 37–47; col. 4, ll. 37–43; col. 4, l. 64– col. 5, l. 3; cols. 7–13 (Tables 1–3)). Uno’s polycarbonate resin and elastomer components, however, are excluded from the composition recited in claim 6 by the “consisting of” transition in the body of the claim. The Examiner responds to Appellant’s arguments in the Answer by indicating that Uno “states that ‘when the isophthalic acid content is less than 3 mol%, the alkali resistance is insufficient, failing to attain the object of the invention. On the other hand, if it exceeds 30 mol%, it is not preferred since the moldability is lowered.” Ans. 6 (citing Uno col. 3, ll. 42– 46). The Examiner asserts that this disclosure “provides evidence [that] regardless of the other components of the composition if the polybutylene terephthalate/ isophthalate copolymer has non preferred amounts of isophthalic acid content the invention will fail,” and, therefore, “[t]he polybutylene terephthalate/isophthalate copolymer provides the composition with the alkali resistance and the moldability.” Id. Appeal 2020-000501 Application 14/780,569 12 Appellant, however, points to Uno’s further disclosure that the amount of polycarbonate resin included in Uno’s thermoplastic resin composition is determined “in view of the balance between the alkali resistance and the fluidity.” Appeal Br. 17 (citing Uno col. 4, ll. 37–43). Appellant also points to Uno’s disclosure that the amount of elastomer included in Uno’s thermoplastic resin composition is determined “in view of the balance between the alkali resistance, the mechanical strength and the moldability. Appeal Br. 17 (citing Uno col. 4, l. 64–col. 5, l. 3). Uno also discloses that if the amount of polybutylene terephthalate resin included in Uno’s thermoplastic resin composition is too high, the content of the remaining components of the composition—the polycarbonate resin, elastomer, and reinforcing fibers—“is relatively lowered excessively and the alkali resistance and the mechanical resistance are deteriorated.” Uno col. 4, ll. 10–17. Appellant also points out that Uno’s experimental examples demonstrate that an isophthalic acid content of 3–30 mol% alone (in the polybutylene terephthalate/isophthalate copolymer) is insufficient to impart alkali resistance to Uno’s thermoplastic resin composition, and also demonstrate that both the polycarbonate resin and the elastomer components, along with the polybutylene terephthalate/isophthalate copolymer, must be present in the composition to achieve satisfactory alkali resistance. Appeal Br. 17–19 (explaining that a comparison of Uno’s Comparative Examples 2 and 6 shows that the polybutylene terephthalate/isophthalate copolymer (having an isophthalic acid content of 3–30 mol%) alone is insufficient to impart alkali resistance; explaining that a comparison of Uno’s Example 1 and Comparative Example 9 shows that a Appeal 2020-000501 Application 14/780,569 13 polycarbonate resin is essential for achieving alkali resistance; and explaining that a comparison of Uno’s Example 1 and Comparative Example 7 shows that an elastomer is essential for achieving alkali resistance); see also Uno col. 7, l. 34–col. 13, l. 48. The Examiner’s response to Appellant’s arguments in the Answer (discussed above) ignores these teachings in Uno and focuses only on Uno’s disclosure that “when the isophthalic acid content is less than 3 mol%, the alkali resistance is insufficient, failing to attain the object of the invention.” Ans. 6. The Examiner, consequently, does not appear to consider Uno’s disclosures as a whole, and what those disclosures reasonably would have suggested to one of ordinary skill in the art—that satisfactory alkali resistance is only achieved if all four components of Uno’s thermoplastic resin composition are included in the composition. 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.”); see also In re Mercier, 515 F.2d 1161, 1165 (CCPA 1975) (“[A]ll of the relevant teachings of the cited references must be considered in determining what they fairly teach to one having ordinary skill in the art.”). Although the Examiner does respond to Appellant’s comparison between Uno’s Example 1 and Comparative Example 9 in the Answer, the Examiner asserts—without providing any objective evidence to support the assertion—that one of ordinary skill in the art would have considered the results of only one of the two alkali resistance tests provided for the composition of Comparative Example 9 (AR-1). Ans. 6–7. The Examiner asserts that the results of alkali resistance test 1 (AR-1) indicate that the Appeal 2020-000501 Application 14/780,569 14 alkali resistance of the composition of Comparative Example 9, which did not include a polycarbonate resin, was satisfactory. Id. As Appellant points out, however, Uno explicitly states that “the alkali resistance” of the composition of Comparative Example 9 “was insufficient,” as determined by the results of both alkali resistance tests (AR-1 and AR-2). Appeal Br. 20– 22 (citing Uno col. 11, l. 21). Contrary to the Examiner’s assertions, Comparative Example 9 thus evidences that inclusion of a polycarbonate resin in combination with a polybutylene terephthalate/isophthalate copolymer, an elastomer, and reinforcing fibers is required for satisfactory alkali resistance, as indicated by the combined results of both alkali resistance tests (AR-1 and AR-2). Considering Uno’s disclosures as a whole—including those disclosures identified by Appellant discussed above—the Examiner does not provide sufficient reasoning having rational underpinning that explains why one of ordinary skill in the art would have included only the mixture of polybutylene terephthalate and (polyalkylene isophthalate)-co-(polyalkylene terephthalate) from Uno’s thermoplastic resin composition in Aluplast’s composition in order to enhance the alkali resistance of Aluplast’s composition, without also including the polycarbonate resin and elastomer components of Uno’s thermoplastic resin composition, so as to arrive at a composition as recited in claim 6. Because the Examiner’s rejection of claim 6 is premised on such a combination, we do not sustain the Examiner’s rejection of claim 6, and claims 7 and 8, which each depend from claim 6, under 35 U.S.C. § 103. In the event of further prosecution of this application, however, we encourage the Examiner and Appellant to consider whether Uno’s polycarbonate resin Appeal 2020-000501 Application 14/780,569 15 and elastomer are encompassed by the “additional thermoplastic materials” recited in claim 6.

Submit an appropriate amendment of the claims so rejected or new evidence relating to the claims so rejected, or both, and have the matter reconsidered by the examiner, in which event the proceeding will be remanded to the examiner. . . . (2) Request rehearing. Request that the proceeding be reheard under § 41.52 by the Board upon the same record. . . . Should Appellant elect to prosecute further before the Examiner pursuant to 37 C.F.R. § 41.50(b)(1), to preserve the right to seek review under 35 U.S.C. §§ 141 or 145 with respect to the affirmed rejection(s), the Appeal 2020-000501 Application 14/780,569 16 effective date of the affirmance is deferred until conclusion of the prosecution before the Examiner unless, as a mere incident to the limited prosecution, the affirmed rejection is overcome. If Appellant elects prosecution before the Examiner and this does not result in allowance of the application, abandonment, or a second appeal, this case should be returned to the Patent Trial and Appeal Board for final action on the affirmed rejection, including any timely request for rehearing thereof. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(1)(iv).
