GREENHUT, LEE L. STEPINA, and JASON W. MELVIN, Administrative Patent Judges. Opinion of the Board filed by MELVIN, Administrative Patent Judge. Opinion dissenting-in-part filed by GREENHUT, Administrative Patent Judge. DECISION ON APPEAL This appeal arises under 35 U.S.C. § 134(a), from a final rejection of claims 1—30.2 We have jurisdiction under 35 U.S.C. § 6(b). We affirm-in-part, designating our affirmances as new grounds of rejection pursuant to 37 C.F.R. § 41.50(b). 1 Appellants identify Airbus Operations Ltd., Airbus Operations GMBH, and Airbus Operations SAS as the real parties in interest. Appeal Br. 2. 2 An oral hearing was conducted on November 21, 2017. Appeal 2016-000996 Application 13/502,175 BACKGROUND The claims are directed to an aircraft horizontal stabiliser fitted with a leading-edge strake. Claim 1, reproduced below, is illustrative: 1. An adjustable, or all-moving, horizontal stabiliser for an aircraft, the stabiliser having a leading edge, a trailing edge, a root and a tip, and a strake fixed with respect to the stabiliser and attached to, or integrally formed with, the stabiliser leading edge adjacent the root. Appeal Br. 108 (Claims App.). REJECTIONS Appellants seek review of the following rejections: 1. Claims 24 and 29 stand rejected under 35 U.S.C. § 112(b) or 35 U.S.C. § 112 (pre-AIA), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter the inventor or a joint inventor, or for pre-AIA the applicant, regards as the invention. Final Act. 2—3. 2. Claims 1, 7—9, 12—15, 19, and 20 stand rejected under 35 U.S.C. § 102(b) as anticipated by Adamson (US 2006/0157613 Al, pub. July 20, 2006). Final Act. 3^4. 3. Claims 2—6, 10, and 11 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Adamson and Ishimitsu (US 4,231,536, iss. Nov. 4, 1980). Final Act. 4—5. 4. Claims 16—18 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Adamson, Ishimitsu, and Lohse (US 6,113,028, iss. Sept. 5, 2000). Final Act. 5—6. 2 Appeal 2016-000996 Application 13/502,175 5. Claims 1 and 21—28 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Jones (US 6,698,688 Bl, iss. Mar. 2, 2004). Final Act. 6—7. 6. Claims 1, 21, 29, and 30 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Jones and Ishimitsu. Final Act. 7—8. 7. Claims 1, 21, 29, and 30 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Morgan (US 2007/0102575 Al, pub. May 10, 2007) and Ishimitsu. Final Act. 8—10. DISCUSSION Indefmiteness Claim 21 recites a device comprising “a horizontal stabiliser of an aircraft.” Appeal Br. 111. Claim24 depends from claim21 and further recites that “the stabiliser is attached to a tail end of an aircraft.” Appeal Br. 111. Claim 29 recites “[a]n aircraft comprising: a main lifting wing; and the device of claim 21 separate from the main lifting wing.” Appeal Br. 112. The Examiner concludes that the phrase “an aircraft” in claims 24 and 29 “is indefinite because it is unclear whether this refers to an additional/altemate aircraft or the same aircraft recited previously in claim 21.” Final Act. 3. Appellants argue that the rejection is based on an improper distinction between “a” and “the” and that “the independent claims at issue are directed to a device for an aircraft, and the dependent claims are directed to an aircraft with that device.” Appeal Br. 11. “A claim is indefinite when it contains words or phrases whose meaning is unclear.” In re Packard, 751 F.3d 1307, 1310-14 (Fed. Cir. 2014) (bracketed alteration omitted); Ex parte McAward, Appeal 2015- 3 Appeal 2016-000996 Application 13/502,175 006416, 2017 WL 3669566, at *5-6 (PTAB Aug. 25, 2017) (precedential) (adopting the Packard standard for claims in examination). Here, we agree with Appellants that the claims are sufficiently clear because the phrase “of an aircraft” in claim 21 merely describes an aspect of the claimed stabilizer—that it must be for use on an aircraft. Stated differently, the phrase “of an aircraft” serves as an adjective or capability of the stabilizer, and the claim language would have the same meaning if written “an aircraft horizontal stabilizer.” No aircraft structure is required by claim 21. Claims 24 and 29, on the other hand, do recite an aircraft structure as an element of the claim. Accordingly, we do not sustain the rejection under § 112. Adamson; Adamson and Ishimitsu; Adamson, Ishimitsu, and Lohse The Examiner finds that Adamson teaches an “adjustable horizontal stabilizer” as “wings of aircraft 600h, being adjustable via the flaps shown in figure 6H.” Final Act. 3. Appellants argue that Adamson does not teach an “adjustable horizontal stabilizer” because the word “adjustable” requires that the entire stabilizer be adjustable, not just flaps on the stabilizer. Appeal Br. 17—18. Appellants point to the Specification, which states: “An ‘adjustable’ horizontal stabiliser is hinged so that its setting (angle of incidence) can be altered with respect to the aircraft fuselage in flight.” Spec. 4:1—2. The Specification clarifies that a hinged flap does not itself make a stabilizer “adjustable” within the context of the described invention: “Both adjustable and fixed horizontal stabilisers typically have a moveable control surface 4 Appeal 2016-000996 Application 13/502,175 (elevator) hinged at the stabiliser trailing edge.” Id. at 4:3—5. The Examiner does not address this argument in the Answer. We agree with Appellants. The Examiner has not shown a teaching in Adamson of a stabilizer where the entire stabilizer is hinged to make its angle of incidence adjustable. Thus, Adamson does not teach “[a]n adjustable, or all-moving, horizontal stabiliser” as claimed. Accordingly, we do not sustain the anticipation rejection of claims 1, 7—9, 12—15, 19, and 20. Because the Examiner relies on the same finding regarding Adamson for the obviousness rejections including Adamson (see Final Act. 4—6; Appeal Br. 36), we also do not sustain the rejection of claims 2—6, 10, and 11 over Adamson and Ishimitsu or the rejection of claims 16—18 over Adamson, Ishimitsu, and Lohse. Jones The Examiner finds that Jones substantially teaches the limitations of claim 1, but “does not specifically teach a strake fixed with respect to the stabiliser, wherein the strake is attached to the stabiliser leading edge adjacent the root, or integrally formed with the stabiliser.” Final Act. 6. The Examiner finds that Jones teaches “a strake fixed with respect to another horizontal stabiliser (101 figure 3), wherein the strake is attached to the stabiliser leading edge adjacent the root, or integrally formed with the stabiliser (shown near 100 in figure 3)” and that a skilled artisan would have found it obvious “to provide the claimed strake on the claimed horizontal stabiliser, since it has been held that rearranging parts of an invention involves only routine skill in the art, and supplying a strake would provide increase [d] aerodynamic performance as does the strake on the other horizontal stabiliser.” Id. 5 Appeal 2016-000996 Application 13/502,175 Appellants argue that the case law does not support the Examiner’s conclusion regarding “rearranging parts” and that the Examiner fails to adequately applying any case law to the facts of this case. Appeal Br. 39- 43. We agree that the Examiner has not provided adequate justification for using Jones’s main-wing strake on Jones’s horizontal stabilizer. As here, the various subcomponents of an aerodynamic surface interact with one another, thus the Examiner has not demonstrated obviousness by relying on rearranging those subcomponents being per se obvious in place of the fact- specific inquiry required by § 103(a). In re Ochiai, 71 F. 3d 1565, 1571 (Fed. Cir. 1995). Appellants also dispute the Examiner’s stated rationale that a skilled artisan would use a strake on Jones’s stabilizer to “provide increased aerodynamic performance,” noting that the Examiner has not provided evidence that the strake would in fact improve performance of Jones’s stabilizer. Appeal Br. 45—48. We agree that the Examiner has not provided adequate support for the finding that the proposed modification of Jones would provide increased aerodynamic performance. The Examiner states that the modification would increase performance “as does the strake on the other horizontal stabilizer” but does not support that Jones’s main-wing strake in fact provides increased performance. Accordingly, we do not sustain the rejection of claims 1 and 21—28 over Jones. Jones and Ishimitsu The Examiner finds that a skilled artisan would have found it obvious “to incorporate the strake taught by Ishimitsu into the stabilizer of Jones in order to enhance aerodynamic capabilities of the horizontal stabilizer where 6 Appeal 2016-000996 Application 13/502,175 enhancement of stabilisers within aircrafts are well known to be desirable within the art of aircraft design.” Final Act. 7. Appellants challenge this finding, asserting first that Ishimitsu does not disclose a horizontal stabilizer. The Examiner, however, does not rely on Ishimitsu for teaching a horizontal stabilizer, so Appellants’ argument focuses on an inapposite distinction. The Examiner relies on Ishimitsu as teaching a strake that will improve aerodynamic performance. Additionally, we do not agree with Appellants that Ishimitsu’s aerodynamic surface is meaningfully distinguishable from the claimed horizontal stabilizer. Appellants argue that “a stabilizer is something for stabilizing, whereas an elevator or a rudder is something used for control” and that “[t]hey are two different things in the conventional arts.” Appeal Br. 72—73. Appellants’ Specification, however, does not support the distinction Appellants attempt to draw. The Specification distinguishes “all- moving” (as claimed) stabilizers, as “combin[ing] the functions of an elevator and horizontal stabiliser.” Spec. 4:9-12. Further, the Specification states that the horizontal stabilizer must satisfy “handling criteria” in order “to provide the pitch necessary for carrying out the desired manoeuvres.” Id. at 2:8—9. Thus, the Specification supports that a “horizontal stabiliser” as claimed does not exclude surfaces that exert control over an aircraft’s attitude. Appellants also argue that Ishimitsu does not teach a strake, because it refers to the aspect of its design as a “strake-like member.” Appeal Br. 73— 74. But Appellants provide no cognizable distinction between Ishimitsu’s “strake-like member” and the claimed strake, other than the label. Additionally, Ishimitsu is not fully consistent in this regard. It does refer to 7 Appeal 2016-000996 Application 13/502,175 its invention as just “strake” in at least certain instances. Ishimitsu 8:52—53 (“It can be seen that the performance is substantially better than the same airfoil without the strake.”); 9:37—39 (“Some separation is also evident on the inboard portion between the trailing vortices from the strakes.”); Fig. 11 (“SMALL STRAKE,” “LARGE STRAKE”). The Specification broadly uses the term “strake” as having “many synonyms, e.g. apex, fillet, vortex generator, chine, fence, leading edge extension (LEX), leading edge root extension (LERX), vane, etc.” Spec. 4:19-23. It also states that “the strake as defined above has a sweep angle at the root which is significantly greater than that of the horizontal stabiliser.” Id. at 5:9—10. That broad usage, in combination with Ishimitsu’s range of teachings, supports the Examiner’s finding that Ishimitsu teaches a strake. Next, Appellants assert that the Examiner has not provided an adequate rationale to support combining Ishimitsu’s strake with Jones’s horizontal stabilizer. Appeal Br. 75—88. The argument takes several forms, the first of which we understand to be that the Examiner has not supported the assertion of improved aerodynamic performance from Ishimitsu’s strake. Id. at 75—78. We agree to the extent that the Examiner does not explain the support for that finding, but we find that Ishimitsu specifically teaches the benefit of its strake. In particular, Ishimitsu presents its Figure 11, outlining the overall aerodynamic performance as “BOOM ELEVATION MOMENT COEFFICIENT,” a measure that Ishimitsu describes as encompassing both lift and drag of the surface. Ishimitsu Fig. 11, 9:7—13 (“[Tjhese test results take into account any increased drag which might result by the addition of the strake-like members and of increased drag resulting from increased angle of incidence, which would tend to cancel out the effects of the increased 8 Appeal 2016-000996 Application 13/502,175 lift.”). Ishimitsu graphs the moment coefficient as a function of the “incidence angle, which is the angle of attack with respect to the air stream.” Id. at 8:34—38. From the test results depicted in Figure 11, Ishimitsu draws two conclusions: a. with both types of advanced technology airfoils tested, the addition of the strake-like member improved performance with regard to the net force imparted to the boom, in that the ruddevators with the strake-like extension improved lift over a wider range of angles of attack, [and] b. the addition of a larger strake-like member improved lift performance beyond what was achieved by the smaller strake- like member. Id. at 8:66—9:6. Thus, Ishimitsu amply supports a finding that its strake will provide increased aerodynamic performance to a moveable aerodynamic surface. Appellants also argue that any aerodynamic enhancement to Ishimitsu’s “ruddervator” would not translate to a horizontal stabilizer. Appeal Br. 78—81. In this regard, Appellants point out that Ishimitsu’s surfaces are positioned with a dihedral angle of 42° from horizontal. Id. at 78; Ishimitsu 5:39-41. Appellants provide no explanation or evidence, however, supporting why a person of skill would expect that angle to change the strake’s behavior. Absent such support, we are not apprised of a reason that the dihedral angle impacts the issues before us. As an aerodynamic surface, the dihedral angle will affect the forces that the surface imparts to the body it is connected to, but we do not understand the changed direction of gravity relative to the surface as a significant factor in the surface’s performance itself. Separate from the dihedral angle, Appellants also assert that Ishimitsu’s “strake-like component enables the refueling boom to 9 Appeal 2016-000996 Application 13/502,175 operate at particularly large angles of attack (around 40 degrees)” and that “[tjhese performance features are irrelevant to Jones, because such an angle of attack would result in stall irrespective of the strake-like component.” Appeal Br. 80. Ishimitsu’s Figure 11, however, shows that the aerodynamic surface itself (as opposed to the refueling boom to which the surface is connected) operates at much more moderate angles of attack. Appellants’ argument regarding the boom angle does not apprise us of error in the Examiner’s rejection. Appellants argue that because Jones is “directed to supersonic transport,” the teachings of Ishimitsu cannot apply. Appeal Br. 82. But Appellants accept that Jones also operates “at low speeds, such as landing and takeoff.” Id. Thus, we do not agree with Appellants’ argument that Ishimitsu’s strake is inapplicable to Jones because Jones can fly at supersonic speeds. In addition, Appellants’ claims relate primarily to the stabilizer itself and do not require any particular characteristics of an aircraft with which the stabilizer is used. Considering all of Appellants’ arguments, we are not apprised of error in the Examiner’s rejection of claim 1 over Jones and Ishimitsu. Appellants rely on the same argument for independent claim 21 (Appeal Br. 89), and do not separately address dependent claims 29 or 30. We therefore affirm the rejection of claims 1, 21, 29, and 30 over Jones and Ishimitsu. Because the Examiner did not rely on Ishimitsu’s support for improved aerodynamic performance from its strake, however, we designate this affirmance regarding claims 1, 21, 29, and 30 as a new ground of rejection. In all other regards, we adopt the Examiner’s findings regarding Jones and Ishimitsu. See Final Act. 7—8. 10 Appeal 2016-000996 Application 13/502,175 Morgan and Ishimitsu The Examiner finds that Ishimitsu teaches a strake “attached or integrally formed with the leading edge adjacent the root.” Final Act. 9-10. The Examiner further finds that it would have been obvious to incorporate Ishimitsu’s strake “into the stabilizer of Morgan.” Id. at 10. Appellants argue that, once combined, any strake of Ishimitsu would not be “attached or integrally formed with the stabiliser leading edge adjacent the root” as claimed because Morgan teaches a stabilizer with a fixed inboard (root) section and an adjustable outboard section. Appeal Br. 92—95. We agree that the Examiner has not adequately explained how the combination of Morgan and Ishimitsu would satisfy the claim language above. Accordingly, we do not sustain the rejection of claim 1, or of claim 30, which depends from claim 1. Claim 21, also subject to the rejection over Morgan and Ishimitsu, does not contain the same “adjacent the root” language. Other than that language, Appellants rely on the same arguments made against the rejection over Jones and Ishimitsu. See Appeal Br. 90-106. Accordingly, we sustain the rejection of claim 21 over Morgan and Ishimitsu for the same reasons described above regarding Jones and Ishimitsu. We likewise sustain the rejection of claim 29, which depends from claim 21. As with our affirmances regarding Jones and Ishimitsu, we designate these affirmances over Morgan and Ishimitsu as new grounds. In all regards other than the reason for using Ishimitsu’s teachings, we adopt the Examiner’s findings regarding Morgan and Ishimitsu. See Final Act. 9. 11 Appeal 2016-000996 Application 13/502,175 NEW GROUNDS OF REJECTION Our affirmance of the rejection of claims 1, 21, 29, and 30 over Jones and Ishimitsu discussed above is based on explanation of the reason that a person of skill would have looked to Ishimitsu that expands somewhat from the Examiner’s statement. We therefore designate our affirmance as a new ground of rejection under 37 C.F.R. § 41.50(b) to provide Appellants with a full and fair opportunity to respond. Because our affirmance of the rejection of claims 21 and 29 over Morgan and Ishimitsu relies on the same expanded explanation, we also designate that rejection as a new ground. DECISION For the above reasons, the Examiner’s rejection of claims 1—30 is affirmed-in-part. We reverse: the rejection of claims 24 and 29 as indefinite; the rejection of claims 1, 7—9, 12—15, 19, and 20 as anticipated by Adamson; the rejection of claims 2—6, 10, and 11 as unpatentable over Adamson and Ishimitsu; the rejection of claims 16—18 as unpatentable over Adamson, Ishimitsu, and Lohse; the rejection of claims 1 and 21—28 as unpatentable over Jones; and the rejection of claims 1 and 30 as unpatentable over Morgan and Ishimitsu. We affirm and designate as including new grounds: the rejection of claims 1, 21, 29, and 30 as unpatentable over Jones and Ishimitsu; and the rejection of claims 21 and 29 as unpatentable over Morgan and Ishimitsu. Section 41.50(b) provides “[a] new ground of rejection pursuant to this paragraph shall not be considered final for judicial review.” Section 41.50(b) also provides: When the Board enters such a non-final decision, the appellant, within two months from the date of the decision, must exercise 12 Appeal 2016-000996 Application 13/502,175 one of the following two options with respect to the new ground of rejection to avoid termination of the appeal as to the rejected claims: (1) Reopen prosecution. 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 prosecution will be remanded to the examiner. The new ground of rejection is binding upon the examiner unless an amendment or new Evidence not previously of Record is made which, in the opinion of the examiner, overcomes the new ground of rejection designated in the decision. Should the examiner reject the claims, appellant may again appeal to the Board pursuant to this subpart. (2) Request rehearing. Request that the proceeding be reheard under §41.52 by the Board upon the same Record. The request for rehearing must address any new ground of rejection and state with particularity the points believed to have been misapprehended or overlooked in entering the new ground of rejection and also state all other grounds upon which rehearing is sought. Further guidance on responding to a new ground of rejection can be found in the Manual of Patent Examining Procedure § 1214.01 (9th Ed., Rev. 07.2015, Nov. 2015). No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l)(iv). AFFIRMED-IN-PART; 37 C.F.R, § 41.50(b) GREENHUT, Administrative Patent Judge, dissenting-in-part. In rejecting claims 24 and 29 under § 112, second paragraph, the Examiner raised a legitimate concern regarding the double inclusion of the phrase “an aircraft.” See, e.g., MPEP § 2173.05(o). It is true that there are no 13 Appeal 2016-000996 Application 13/502,175 per se rules that double inclusion renders a claim indefinite. See Id. However, contrary to Appellants’ argument simply dismissing this issue as the Examiner’s overly mechanical application of a per se rule, the Examiner did not apply a per se rule in making this rejection. The Examiner provided a specific example of why, in this particular context, the double recitation of “an aircraft” renders the scope of claims 24 and 29 unclear. Ans. 9. The Examiner explained, with reference to Ishimitsu, that, for example, ruddervator 24 could be considered a “stabiliser for” the boom’s expanded housing 22, “an aircraft,”3 according to claim 1, while being “attached to the tail end of’ a different aircraft, tanker 10, according to claim 24, or a component of that different aircraft according to claim 29. Id. The Examiner correctly pointed out, and Appellants do not dispute, that nothing in the Specification suggests the claims should be interpreted to cover a stabilizer “for” one aircraft that is “attached to the tail end of,” or a component of, another aircraft. Appellants simply dismiss the Examiner’s reliance on Ishimitsu as “meaningless.” App. Br. 8—9. However, this is not correct. Prior art references can often provide useful examples of why the scope of the claimed subject matter may not be sufficiently definite because the very purpose of the definiteness requirement is so that a claim may be evaluated against the prior-art or a potentially infringing product. In re Hammack, 427 F.2d 1378, 1382 (CCPA 1970). One might consider this situation to relate only to the breadth of the claim, in that it seems evident that the “aircraft” of claim 1 can simply be a 3 The potential issue of whether the housing 22 and ruddervator 24 could be considered “an aircraft” does not detract from the Examiner’s example which could similarly apply to any towed aircraft. 14 Appeal 2016-000996 Application 13/502,175 different aircraft that that of claims 24 and 29. See, e.g., MPEP § 2174 (citing In re Borkowski, 422 F.2d 904 (CCPA 1970)). However such a construction requires reading the claims in isolation, as broadly as possible while our task is to read the claims in light of the Specification, only as broadly as reasonable. The PTO should not be applying a claim construction so remote from the Specification that it results a breadth that renders the claim lacking sufficient supporting disclosure under § 112, first paragraph. See, e.g., In re Wolfensperger 302 F. 2d 950, 954 (CCPA 1962). It is this inability to give meaning to the express language of the claims while at the same time interpreting them in light of the Specification that results in an unreasonable degree of uncertainty as to the claim scope. See, e.g., MPEP § 2173.03 (citing, inter alia, In re Cohn, 438 F.2d 989, (CCPA 1971)). The majority attempts to resolve this issue by recasting the claim phrase “horizontal stabiliser for an aircraft” to read “an aircraft horizontal stabiliser.” First, I cannot agree that these phrases necessarily have the same meanings. The phrase actually recited attributes the stabilizer’s use, presumably for stabilization, to a particular aircraft, whereas the majority’s language could more reasonably be regarded as referring to aircraft generally. Ignoring the word “an” so that claim 1 recited “a horizontal stabiliser for aircraft” would have a similar effect. Second, and more importantly, these issues are not ripe for our review because it is not our charge to ignore words in a claim or recast claims on behalf of Appellants. In prosecution before the PTO “it is the applicants’ burden to precisely define the invention, not the PTO’s.” In re Morris, 127 F. 3d 1048, 1056 (Fed. Cir. 1997). The Examiner was justified in requiring the Appellants to resolve this ambiguity during prosecution while Appellants have the 15 Appeal 2016-000996 Application 13/502,175 opportunity to do so. See Ex Parte Miyazaki, 89 USPQ2d 1207, 1211 (BPAI 2008) accord In re Packard, 751 F.3d 1307, (Fed. Cir. 2014). “An essential purpose of patent examination is to fashion claims that are precise, clear, correct, and unambiguous. Only in this way can uncertainties of claim scope be removed, as much as possible, during the administrative process.” In re Zletz, 893 F. 2d 319, 322 (Fed. Cir. 1989). Rejections under § 112, second paragraph, are the appropriate, if not the only, mechanism by which the Examiner can raise these types of issues of claim clarity. Appellants’ arguments are simply dismissive and do not provide any meaningful analysis of the legal issues raised by the Examiner. If the Examiner’s articulation of the basis for the rejection was not sufficiently informative, we have recourse to resolve any potential issues of notice under 37 C.F.R. § 41.50(b). For the foregoing reasons, I respectfully dissent from the majority’s decision to reverse the Examiner’s rejection under 35U.S.C. § 112, second paragraph. I join in the remainder of the majority’s well-reasoned analysis. 16 Copy with citationCopy as parenthetical citation
