LESLIE Appeal 2018-001346 Application 14/644/596 Technology Center 3700 Before DANIEL S. SONG, FREDERICK C. LANEY, and BRENT M. DOUGAL, Administrative Patent Judges. SONG, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Pursuant to 35 U.S.C. § 134(a), Appellant1 appeals from the Examiner’s decision to reject claims 1–24. We have jurisdiction under 35 U.S.C. § 6(b). 1 We use the word Appellant to refer to “applicant” as defined in 37 C.F.R. § 1.42(a). Appellant identifies the real party in interest as United Technologies Corporation. Appeal Br. 2. Appeal 2018-001346 Application 14/644,596 2 We AFFIRM-IN-PART. CLAIMED SUBJECT MATTER The claims are directed to a stator assembly for a gas turbine engine. Claim 1, reproduced below, is illustrative of the claimed subject matter: 1. A vane cluster for a gas turbine engine, comprising: a first end-of-cluster vane; a second end-of-cluster vane; a neighbor vane adjacent to said second end-of-cluster vane at an interface that includes an angled load interface therebetween; and a multiple of base vanes between said first end-of-cluster vane and said neighbor vane, said angled load interface different than an interface between each of said multiple of base vanes. Appeal Br. 14, Claims App’x. (emphasis added). REJECTIONS 1. The Examiner rejects claims 8 and 16–242 are rejected under 35 U.S.C. § 112(b) or 35 U.S.C. § 112 (pre-AIA), second paragraph, as indefinite. Final Act. 5. The Examiner also rejects various claims under 35 U.S.C. §102(a)(2) (as far as claims 8 and 16–20 are found to be definite and understood) as follows3: 2 Although the heading of the Final Office Action indicates claims 8 and 16– 23, this appears to be a typographical error because the deficiencies of claim 24 is explicitly discussed in the rejection. Final Act. 5. Moreover, claim 24 depends from claim 23. Appeal Br. 21, Claims App’x. 3 The rejection of claims 1–24 as anticipated by Earl (US 2014/0060081 A1, pub. Mar. 6, 2014) has been withdrawn. Ans. 3. Appeal 2018-001346 Application 14/644,596 3 2. Claims 1–21 as anticipated by Ring (US 2014/0093363 A1, pub. Apr. 3, 2014). Final Act. 9. 3. Claims 1–3, 8–14, and 21 as anticipated by Fournier (US 5,743,711, iss. Apr. 28). Final Act. 12. 4. Claims 1, 8–10, 11–14, and 21 as anticipated by Yamashita (US 2006/0177314, pub. Aug. 10, 2006). Final Act. 14. OPINION Rejection 1: Indefiniteness The Examiner rejects claims 8 and 16–24 as indefinite because numerous recitations lack proper antecedent bases, appear to improperly reference previously recited elements, and other issues noted in the Final Action as examples of indefiniteness. Final Act. 5. The record indicates that the Appellant sought to amend these claims after the Final Action, but these amendments were not entered. Advisory Act. 1–2 (Dec. 23, 2016). The Appellant does not address this rejection in its briefs in the present appeal. Accordingly, we summarily affirm the indefiniteness rejection of claims 8 and 16–23. Rejection 2: Ring The Examiner rejects claims 1–21 as anticipated, finding that Figures 2 and 3 of Ring discloses a neighbor vane (immediately to the right of the vane near 30A in figure 3) adjacent to the second end-of-cluster vane at an interface that includes an angled load interface therebetween; and a multiple of base vanes 30 between the first end-of-cluster vane and the neighbor vane, the angled interface different than an interface between each of the multiple of base vanes. Final Act. 9–10. Appeal 2018-001346 Application 14/644,596 4 The Appellant disagrees and argues, inter alia, that “Ring fails to disclose that the angled load interface is different than the interface between each of said multiple of base vanes (106) as recited in the claims.” Appeal Br. 9. In that regard, the Appellant points out that “each of the vanes 30 disclosed by Ring are identical,” and argues that “the Examiner is essentially reading out Applicant’s specific reference of vane types,” including end-of- cluster vanes, neighbor vanes, and/or base vanes, which result in different interfaces therebetween. Appeal Br. 10. The Examiner explains that “[m]erely designating the vanes in the appealed claims as a first end-of-cluster vane, a second end-of-cluster vane, a neighbor vane, and base vanes, does not impart patentability, absent a claimed feature that defines over the prior art.” Ans. 4. According to the Examiner, the limitation at issue italicized above is “sufficiently broad so that it reads on the location of the unnumbered angled load interface (between the neighbor vane and the second end-of-cluster vane) being at a different location than the unnumbered interface between each of the multiple of base vanes.” Final Act. 10; Ans. 4. We agree with the Appellant. We do not disagree with the Examiner that merely designating vanes based on their position does not necessarily impart patentability. However, the claims recite an interface between one pair of adjacent vanes (neighbor vane and second end-of-cluster vane) defines “an angled load interface therebetween.” The claims also recite multiple base vanes and require the interface defined between these same base vanes to be different than the angled load interface. The Examiner’s position that the requirement that the angled load interface be different than the interface between the multiple base vanes is merely met by an interface “being at a different location” is an unreasonably broad interpretation of the Appeal 2018-001346 Application 14/644,596 5 claim. Under such interpretation, all of the interfaces, including all of the interfaces between the multiple base vanes, would be different from each other by virtue of being at different locations. The claims recite that the angled load interface itself is different from the interface of the base vanes, such that the character of the interfaces must be different, not merely different in location. This interpretation of the claims is supported by the Specification, which discloses a specific function of the recited angled load interface as compared to the interfaces of the base vanes. See Spec. ¶¶ 51, 53, 55–57; Fig. 7. While the PTO is obligated to give claims their broadest reasonable interpretation, “any such construction [must] be ‘consistent with the specification, . . . and . . . claim language should be read in light of the specification as it would be interpreted by one of ordinary skill in the art.’” In re Suitco Surface, Inc., 603 F.3d 1255, 1259-60 (Fed. Cir. 2010) (quoting In re Bond, 910 F.2d 831, 833 (Fed. Cir. 1990). “[I]t would be unreasonable for the PTO to ignore any interpretive guidance afforded by the applicant’s written description.” In re Morris, 127 F.3d 1048, 1054 (Fed. Cir. 1997). Therefore, in view of the above, we reverse the rejection of claims 1– 21 as being anticipated by Ring because it is premised on an unreasonably broad interpretation. The remaining arguments of the Appellant directed to claims 18–20 are moot. App. Br. 12–13 Rejection 3: Fournier The Examiner rejects claims 1–3, 8–14, and 21 as anticipated, finding that Figures 14–19 of Fournier discloses a neighbor vane (immediately to the circumferential right of the second cluster vane) adjacent to the second [circumferentially Appeal 2018-001346 Application 14/644,596 6 leftmost] end-of-cluster vane at an interface that includes an angled load interface therebetween; and a multiple of base vanes l6b between the first end-of-cluster vane and the neighbor vane, the angled interface different than an interface between each of the multiple of base vanes. Final Act. 12–13. The Examiner again explains that the limitation at issue is “sufficiently broad” so as to be satisfied by the differing locations of the interfaces. Final Act. 13; Ans. 6. The Appellant points out that as with Ring, “Fournier also discloses only identical vane platforms,” and argues that Fournier “fails to disclose an angled load interface different than the interface between a multiple of base vanes as recited.” Appeal Br. 11. Like Rejection 2 based on Ring, this anticipation rejection based on Fournier is premised on the same unreasonably broad interpretation of the claims. Thus, we reverse the rejection. Rejection 4: Yamashita The Examiner rejects claims 1, 8–10, 11–14, and 21 as anticipated, finding that Yamashita discloses a first circumferentially rightmost end-of-cluster vane analogous to element 3; a second end-of-cluster vane 1b; a neighbor vane 1a adjacent to the second end-of-cluster vane at an interface that includes an angled load interface near 7, 8 there between; and a multiple of base vanes 3 between the first end-of-cluster vane and the neighbor vane, the angled interface different than an interface between each of the multiple of base vanes. Final Act. 14. In that regard, the Examiner asserts that “element 1, collectively formed by blade profiles 2, is a ‘vane’ cluster, since blades are also commonly referred to as ‘vanes’ in the art.” Final Act. 14. Appeal 2018-001346 Application 14/644,596 7 The Appellant disagrees, and argues, inter alia, that “the Examiner attempts to equate [] vanes to blades; however, vanes are stationary and are attached in a manner different than blades –– certainly not to a disc. Blades are attached to a disc which rotates as best seen in Figure 1 of Yamashita.” Appeal Br. 11–12. According to the Appellant, “[u]nder no reasonable interpretation would one of ordinary skill in the art would consider blades to be equivalent to vanes.” Appeal Br. 12. The Examiner responds that The appealed claims do not contain any requirement that the claimed vanes are stationary. A vane is any device which serves to direct fluid, and there is no requirement that a vane must be stationary. It is well-settled that although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. Ans. 8. We again agree with the Appellant. In the Specification, the Appellant clearly distinguishes between “vanes” and “blades.” Spec. ¶ 4 (“The compressor section includes a case circumscribing an engine axis and axially alternating arrays of stationary vanes and rotatable blades.”); Spec. ¶ 45 (“Each of the rotor assemblies 62 includes a multiple of blades 72 supported by a respective rotor hub 74. The outer platform 68 and airfoils 66 of the vane arrays 60 and a platform 76 that extends from each of the multiple of blades 72 generally bounds the airflow passage 64.”); Fig. 2 (“stator vane airfoils [66]”, “blades [72]” of “rotor hub [74]”). Although the Examiner is correct that limitations from the Specification are not read into the claims, the claims are interpreted from the perspective of one of ordinary skill in the art (in this case, the turbine engine art) in view of the Specification. We do not view the Appellant’s argument Appeal 2018-001346 Application 14/644,596 8 as reading the limitation of “stationary” into the claim, but rather, as arguing that a person of ordinary skill in the art of turbine engines would interpret the claims to be directed, and limited to, vanes of a stator, and not to encompass blades of a rotor. We agree with the Appellant that in interpreting the claims in view of the Specification, a person of ordinary skill in the art of turbine engines would understand that the subject invention is directed to vanes of a stator specifically, and not to the blades of a rotor hub. There is no dispute that Yamashita is directed to turbine rotor blades instead of a stator. Yamashita, Abstract (“A set of turbine rotor blades is arranged on a rotor disk.”). Therefore, we agree with the Appellant that Yamashita fails to anticipate the claims, and reverse the rejection. Miscellaneous Claims The Appellant also submits arguments directed to claims 22–24, arguing that the limitations therein are not disclosed in the prior art references, or the reference Earl. Appeal Br. 13–14. However, these claims are only rejected relative to the indefiniteness rejection, which is not contested by the Appellant, and the rejection based on Earl has been withdrawn. See Ans. 10. Accordingly, these arguments are moot. CONCLUSION The Examiner’s rejections are AFFIRMED-IN-PART. More specifically, we affirm the indefiniteness rejections of claims 8 and 16–24. However, we reverse the anticipation rejections based on Ring, Fournier, and Yamashita.
