KOONANKEIL ____________________ Appeal 2019-006546 Application 15/030,236 Technology Center 2800 ____________________ Before ROMULO H. DELMENDO, KAREN M. HASTINGS, and JULIA HEANEY, Administrative Patent Judges. HASTINGS, Administrative Patent Judge. DECISION ON APPEAL Appellant1 appeals under 35 U.S.C. § 134(a) from the Examiner’s rejections of claims 1–4, 6–16, 18, and 19. We have jurisdiction over the appeal under 35 U.S.C. § 6(b). We AFFIRM. 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. 1). Appeal 2019-006546 Application 15/030,236 2 Independent claims 1 and 8 below are illustrative of the subject matter on appeal: 1. A method of inspecting a component of a gas turbine engine, comprising: performing a through-hole inspection; and determining locations of a plurality of holes from results of the through-hole inspection, wherein the results of the through-hole inspection include a plurality pixels2, and wherein a blockage is identified when a number of pixels within an acceptable hole location is below a minimum threshold. 8. A method of inspecting a component of a gas turbine engine, comprising: performing a through-hole inspection, wherein the results of the through-hole inspection include a plurality of sets of pixels, each of the sets of pixels corresponding to one of a plurality of holes; and determining locations of the plurality of holes from results of the through-hole inspection by identifying one of (1) a centroid of a corresponding one of the plurality of sets of pixels and (2) a pixel on a perimeter of a corresponding one of the plurality of sets of pixels. Independent claim 14 recites an inspection assembly with a controller configured to perform a through-hole inspection on an engine component (Appeal Br. Claims Appendix 14). The following rejections are on appeal: 1) claims 1–4, 6–16, 18, and 19 under 35 U.S.C. § 112(b) as indefinite. 2 Appellant states that “plurality pixels” is a “minor typographical error”, and Appellant is willing to correct this to be “plurality of pixels” (Appeal Br. 6). Appeal 2019-006546 Application 15/030,236 3 2) claims 1–4, 6–9, and 11 under 35 U.S.C. §§ 102(a)(1) and (a)(2) as anticipated by Key (US 2011/0119020 A1; May 19, 2011); 3) claim 10 under 35 U.S.C. § 103 as unpatentable over the combined prior art of Key and Marshall (US 2012/0256920 A1; Oct. 11, 2012); 4) claims 12–16, 18, and 19 under 35 U.S.C. § 103 as unpatentable over the combined prior art of Key and Drescher (US 2012/0188380 A1; July 26, 2012). ANALYSIS The § 112(b) rejection for indefiniteness During prosecution, claims are interpreted using “the broadest reasonable meaning of the words in their ordinary usage as they would be understood by one of ordinary skill in the art, taking into account whatever enlightenment by way of definitions or otherwise that may be afforded by the written description contained in the applicant’s specification.” In re Morris, 127 F.3d 1048, 1054 (Fed. Cir. 1997). See also In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1364 (Fed. Cir. 2004) (the scope of the claims in patent applications is determined by giving claims their broadest reasonable construction in light of the specification as it would be interpreted by one of ordinary skill in the art); Phillips v. AWH Corp., 415 F.3d 1303, 1315 (Fed. Cir. 2005) (the specification is always highly relevant to the claim construction analysis, and is usually dispositive as it is the single best guide to the meaning of any disputed terms). Appeal 2019-006546 Application 15/030,236 4 Claims are definite if they “set out and circumscribe a particular area with a reasonable degree of precision and particularity. It is here where the definiteness of the language employed must be analyzed—not in a vacuum, but always in light of the teachings of the prior art and of the particular application disclosure as it would be interpreted by one possessing the ordinary level of skill in the pertinent art.” In re Moore, 439 F.2d 1232, 1235 (CCPA 1971). However, “breadth [of a claim] is not to be equated with indefiniteness.” In re Miller, 441 F.2d 689, 693 (CCPA 1971). The Examiner found the language of claim 1 indefinite, and parses the meaning of numerous claim phrases, often independently from the claim language as a whole (Non-Final Act. 3–8). Notably, the Examiner admits that one skilled in the art could “determine what the claims could mean” (Ans. 3) but reasons that the metes and bounds are not defined as “the relationship between” the claimed elements “is not laid out” (id.). Claim 1 is broad in the sense that it de facto reads on any method of inspecting a gas turbine engine component wherein the presence of a hole or blockage therein is determined based on an analysis of a number of pixels. However, claim 1 is not indefinite on the basis of its breadth alone. In re Miller, 441 F.2d at 693; see also In re Gardner, 427 F.2d 786, 788 (CCPA 1970) (“Breadth is not indefiniteness.”). The Examiner, however, has not explained sufficiently why one of ordinary skill in the art would not have understood how to use the method(s) of determining pixels in the manner described in the Specification, as explained in Appellant’s response, e.g., using a flow thermography process with a thermal imaging infrared camera (Spec. ¶¶ 4, 6, 30, 45; Appeal Br. 5–8; Reply Br. 1, 2). Appeal 2019-006546 Application 15/030,236 5 Appellant has persuasively reasoned that the Examiner’s § 112(b) rejection is based on the Examiner’s belief that “the claims are too broad” (Reply Br. 2; Appeal Br. 5–8). In light of these circumstances, we agree with Appellant that one of ordinary skill in the art would have understood the broad scope of the claims in light of the Specification. Accordingly, we cannot sustain the Examiner’s rejection of the claims as being indefinite. The §§ 102 and 103 Rejections We have reviewed each of Appellant’s arguments for patentability. However, we determine that a preponderance of the evidence supports the Examiner’s finding that the claimed subject matter of representative claims 1 and 8 are anticipated within the meaning of § 102 in view of the applied prior art of Key as well as the Examiner’s obviousness determination of claim 14. Accordingly, we sustain the Examiner’s §§ 102 and 103 rejections on appeal for essentially those reasons expressed in the Answer, including the Examiner’s Response to Argument section. We add the following primarily for emphasis. We review the appealed rejections for error based upon the issues identified by Appellant and in light of the arguments and evidence produced thereon. Ex parte Frye, 94 USPQ2d 1072, 1075 (Fed. Cir. 2011) (BPAI 2010) (precedential), cited with approval in In re Jung, 637 F.3d 1356, 1365 (Fed. Cir. 2011) (“[I]t has long been the Board’s practice to require an applicant to identify the alleged error in the examiner’s rejections.”). “[T]he PTO must give claims their broadest reasonable construction consistent with the specification. Therefore, we look to the specification to Appeal 2019-006546 Application 15/030,236 6 see if it provides a definition for claim terms, but otherwise apply a broad interpretation.” In re ICON Health & Fitness, Inc., 496 F.3d 1374, 1379 (Fed. Cir. 2007) (citation omitted). “[A]s applicants may amend claims to narrow their scope, a broad construction during prosecution creates no unfairness to the applicant or patentee.” Id. Appellant argues that Key does “not teach identifying a blockage when a number of pixels within an acceptable hole location is too low” as recited in claim 1 (Appeal Br. 9). Similarly Appellant argues that Key does not teach determining a hole location in the manner recited in claim 8, as Key “identifies only its thermally significant pixels, groups them based on their film cooling effect, and then defines their centroid” (id.). These arguments are not persuasive of reversible error in the Examiner’s rejection of claims 1 and 8, because they fail to fully address the applied prior art and the inferences that one of ordinary skill in the art would have made therefrom. Notably, Appellant does not explicitly address the Examiner’s analysis of Key’s Fig. 21, which details classifying holes as partially blocked, blocked, or “thru” (i.e., open) (Ans. 17, Key ¶¶ 17–19, 81, 86, 87). Appellant’s process as described in the Specification (and dependent claims 2–4) uses a flow thermography process, which uses an infrared camera to detect heat patterns and flow. Likewise, Key uses an “infrared inspection machine” (Key ¶ 55) to obtain an “infrared signature” for each “individual film cool feature” (i.e., each hole in the gas turbine blade) (Key abstract). Furthermore, as pointed out by the Examiner, Key determines whether holes are blocked or missing in a gas turbine engine component based on a pixel count (Ans. 16–18). One of ordinary skill would have readily inferred Appeal 2019-006546 Application 15/030,236 7 that a blocked hole is identified when the pixel count is lower than a pixel count for an unblocked hole/cooling feature of Key. In re Preda, 401 F. 2d 825, 826 (CCPA 1968) (In determining whether a reference anticipates the subject matter recited in a claim, “it is proper to take into account not only specific teachings of the reference but also the inferences which one skilled in the art would reasonably be expected to draw therefrom.”) With respect to claim 8, as pointed out by the Examiner, the film cooling effect location of Key is determined by the hole location, and Key teaches calculation of the centroid of the film cooling effect (Ans. 19; Key e.g., Figs. 10A, 10B, ¶ 81). As shown in Figs. 10A and 10B, a “Film Cooling Feature” is a hole in the gas turbine component. In light of these circumstances, Appellant has not shown reversible error in the Examiner’s findings that the language of each of claim 1 and claim 8 encompasses Key’s infrared imaging method that uses pixels to determine hole locations (that is, a film cooling feature) and blockages. With respect to independent claim 14 and its dependent claim 16, Appellant argues that Key does not identify misaligned holes, or blocked or partially blocked holes, because it only identifies cooling effects (Appeal Br. 10, 11). As pointed out by the Examiner, a film cooling feature is a hole location (Ans. 19, 20) and Key does base its determination of blocked or partially blocked holes based on the number of pixels (Ans. 21; Key, e.g., Fig. 21, ¶ 81). One of ordinary skill would have reasonably inferred that less pixels than a full count of pixels for an open hole means a partial or fully blocked hole. One of ordinary skill would have also reasonably inferred that a defective “film cooling feature” hole as exemplified in Fig. 10B of Key can be viewed as a misaligned hole. Furthermore, Appellant Appeal 2019-006546 Application 15/030,236 8 does not even address the Examiner’s findings that Drescher also verifies locations of holes in a turbine component based on image analysis to determine the centroid of cooling air exit hole expressed as a pixel location (Non-Final Act. 12, 13). Thus, Appellant’s arguments are not persuasive of reversible error in the Examiner’s obviousness rejection, because they fail to fully address the applied prior art and the inferences that one of ordinary skill in the art would have made therefrom. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007) (It has been established that “the [obviousness] analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.”); see also id. at 421 (“A person of ordinary skill is also a person of ordinary creativity, not an automaton.”); Ball Aerosol & Specialty Container, Inc. v. Limited Brands, Inc., 555 F.3d 984, 993 (Fed. Cir. 2009) (Under the flexible inquiry set forth by the Supreme Court, the PTO must take account of “the inferences and creative steps,” as well as routine steps, that an ordinary artisan would employ.). Appellant does not present any further arguments with respect to the remaining dependent claims, including claim 10 rejected separately (Appeal Br. 11).
