HILL, Administrative Patent Judges. STAICOVICI, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Daniel Charles Pappone et al. (Appellants) appeal under 35 U.S.C. § 134 from the Examiner’s decision rejecting, under 35 U.S.C. § 103(a), claims 1, 4–6, 8–11, 16, 21, and 22. Claims 12–15, 17, and 18 have been withdrawn and claims 2, 3, 7, 19, and 20 have been canceled. We have jurisdiction over this appeal under 35 U.S.C. § 6(b). Appeal 2012-003183 Application 11/261,489 3 INVENTION Appellants’ invention relates to “a method and apparatus for testing the steam system of a boiling water reactor (BWR).” Spec. 1, para. 1. Claim 1 is illustrative of the claimed invention and reads as follows: 1. A system for monitoring the affect of acoustic loads expected on boiling water reactor (BWR) steam dryers, comprising: a BWR scale model, the BWR scale model including a scale model of a reactor pressure vessel and a system dryer; a test fixture located upstream of the BWR scale model, the test fixture configured to generate and supply air flow, and associated acoustic loads, into the BWR scale model; at least one measurement device attached to the BWR scale model and configured to monitor system behavior of the BWR scale model to predict how acoustic loads affect plant operation at the BWR; and at least one main steam line located downstream of the BWR scale model, wherein the at least one main steam line includes at least one adjustable component, the adjustable component including at least one of a pipe length adjuster and a relief valve inlet length adjuster. REJECTIONS The following rejections are before us for review: I. The Examiner rejected claims 1, 5, 9–11, and 21 under 35 U.S.C. § 103(a) as unpatentable over “Evaluation of Flow Induced Vibration for Fixed Typed Guide Rods of Shroud Head and Steam Dryer in ABWR,” Shirou Takahashi et al, Proceedings of the 10th International Conference on Nuclear Engineering ICONE 10, Volume 1, p. 727–34, The American Society of Mechanical Engineers (2002) (hereafter “Takahashi”), Bilanin (US 2006/0078081 A1, pub.

II. The Examiner rejected claim 8 under 35 U.S.C. § 103(a) as unpatentable over Takahashi, Bilanin, Feenstra, and “Study on Acoustic Resonance and Its Damping of BWR Steam Dome,” Masaya Ohtsuka et al. (hereafter “Ohtsuka”). III. The Examiner rejected claim 16 under 35 U.S.C. § 103(a) as unpatentable over Takahashi, Bilanin, Feenstra, and “Flutter Model Technology,” Ron Busan, Wright Laboratory Final Report (January 1998) (hereafter “Busan”). IV. The Examiner rejected claim 4 under 35 U.S.C. § 103(a) as unpatentable over Takahashi, Bilanin, Feenstra, and Brown (US 3,665,964, iss. May 30, 1972). V. The Examiner rejected claim 6 under 35 U.S.C. § 103(a) as unpatentable over Takahashi, Bilanin, Feenstra, and Bittermann (US 6,333,956 B1, iss. Dec. 25, 2001). VI. The Examiner rejected claim 21 under 35 U.S.C. § 103(a) as unpatentable over Takahashi, Bilanin, Feenstra, and Fargo (US 5,289,901, iss. Mar. 1, 1994). VII. The Examiner rejected claim 22 under 35 U.S.C. § 103(a) as unpatentable over Takahashi, Bilanin, Feenstra, and Livada (SU 1229506 A1, pub. May 7, 1986) or Motoki (JP 41-0085161 A, pub. Apr. 7, 1998). Appeal 2012-003183 Application 11/261,489 5 SUMMARY OF DECISION We REVERSE. ANALYSIS Rejection I The Examiner found that Takahashi discloses a system for monitoring the effect of acoustic loads expected on BWR steam dryers using a BWR scale model and at least one measurement device attached to the BWR scale model to monitor system behavior and predict acoustic loads. Ans. 6 (citing Takahashi, p. 729, paras. 3 and 4 and Figs. 4 and 5). The Examiner further found that Bilanin discloses “a BWR system which includes at least one main steam line (A, B, C, D) located downstream of the BWR model…and at least one adjustable component.” Ans. 7 (citing Bilanin, Figs. 2, 4, and 6). Finally, the Examiner found that Feenstra discloses a test fixture for generating and supplying airflow associated with “acoustic loads to the BWR scale model.” Id (citing Feenstra, p. 269, col. 2, para. 2 and Fig. 1). The Examiner then concludes that it would have been obvious to include the at least one steam line and adjustable component of Bilanin into Takahashi’s system “to facilitate monitoring of acoustic pressure loads within a BWR steam dome without the need to make measurements within the BWR steam dome.” Id (citing Bilanin, para. 7). The Examiner further concluded that it would have been obvious to include the test fixture of Feenstra into the system of Takahashi and Bilanin in order to “simulate real BWR operating conditions (e.g. flow behavior, acoustic load generation, etc.).” Ans. 8. Appellants argue that because (1) the BWR scale model of Takahashi’s system is designed to use water; (2) the steam lines of Bilanin’s BWR use steam; and (3) Feenstra’s test fixture is used in a wind tunnel, a Appeal 2012-003183 Application 11/261,489 6 person having ordinary skill in the art would not have combined the teachings of Takahashi, Bilanin, and Feenstra as proposed by the Examiner. App. Br. 17–19 and 24–261; see also Reply Br. 5–6. We agree. It is undisputed that Takahashi fails to disclose at least one main steam line located downstream of the BWR scale model. Ans. 6–7. Bilanin discloses a system and method for estimating the “fluctuating pressure loads on components . . . within a BWR steam dome using pressure time history measurements made on components of the BWR facility external to the steam dome.” Bilanin, Abstract. Although Bilanin discloses that it is known to take pressure measurements on the main steam lines of a BWR, we find the rejection insufficient to explain what in the prior art would have prompted a person having ordinary skill in the art to provide steam lines to Takahashi’s BWR scale model which uses water, and not steam. Furthermore, the reason proffered by the Examiner, i.e., “to facilitate monitoring of acoustic pressure loads within a BWR steam dome without the need to make measurements within the BWR steam dome” (Ans. 7), appears to already be adequately performed by Takahashi’s system because Takahashi uses measurements obtained from a BWR scale model and not from a full scale BWR. Moreover, the Examiner has not provided any findings that either Takahashi or Bilanin recognized a problem with Takahashi’s water based BWR scale model to require its modification to a steam based BWR model, as the Examiner proposes. Absent hindsight, we fail to see why a person having ordinary skill in the art would have been led 1 Appellants did not provide page numbers on the Appeal Brief. However, for ease of referring to Appellants’ arguments, we have assigned page numbers 1 through 37 to the Appeal Brief. Appeal 2012-003183 Application 11/261,489 7 by the teachings of Bilanin to modify Takahashi’s water based BWR scale model in the manner claimed. The Examiner’s use of the teachings of Feenstra does not remedy the deficiency of Takahashi and Bilanin as described supra. See Ans. 7-8. Accordingly, for the foregoing reasons, we do not sustain the rejection under 35 U.S.C. § 103(a) of claims 1, 5, 9–11, and 21 as unpatentable over Takahashi, Bilanin, and Feenstra. Rejections II-VII The combined teachings of Takahashi, Bilanin, and Feenstra form the basis of these rejections. The Examiner’s use of the teachings of Ohtsuka , Busan, Brown, Bittermann, Fargo, and either Livada or Motoki does not remedy the deficiencies of Takahashi, Bilanin, and Feenstra. See Ans. 11– 19. Accordingly, for the reasons discussed supra, we also do not sustain Rejections II through VII. SUMMARY The Examiner’s decision to reject claims 1, 4–6, 8–11, 16, 21, and 22 is reversed.
