SILVERMAN, Administrative Patent Judges. JEFFERY, Administrative Patent Judge. DECISION ON APPEAL Under 35 U.S.C. § 134(a), Appellant1 appeals from the Examiner’s decision to reject claims 26–36. We have jurisdiction under 35 U.S.C. § 6(b). We REVERSE. 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies the real party in interest as Zodiac Pool Systems, LLC. Appeal Br. 4. Appeal 2019-000420 Application 15/665,754 2 STATEMENT OF THE CASE Appellant’s invention establishes communications with equipment and devices for retrofitting or otherwise furnishing to pool and spa equipment communication capabilities via radio frequency signals or otherwise. See generally Spec. 1. Claim 26 is illustrative: 26. A method of determining whether a strainer of a component of a pool- or spa-water circulation system is clogged with debris, comprising: a. mechanically connecting to the component a first device including a first pressure sensor and a first electronic transmitter; b. electronically transmitting pressure values obtained by the first pressure sensor to a first location remote from the component; and c. evaluating the transmitted pressure values to determine whether the strainer of the component is clogged with debris. THE REJECTIONS The Examiner rejected claims 26–35 under 35 U.S.C. § 103 as unpatentable over Stiles, Jr. (US 2010/0092308 A1; published Apr. 15, 2010) (“Stiles”), Spiegel (US 6,651,454 B1; issued Nov. 25, 2003), and Hamza (US 2006/0201556 A1; published Sept. 14, 2006). Final Act. 2–7.2 The Examiner rejected claim 36 under 35 U.S.C. § 103 as unpatentable over Stiles, Spiegel, Hamza, and Wien (US 2011/0025511 A1; published Feb. 3, 2011). Final Act. 7–10. THE REJECTION OVER STILES, SPIEGEL, AND HAMZA 2 Throughout this opinion, we refer to (1) the Final Rejection mailed June 12, 2018 (“Final Act.”); (2) the Appeal Brief filed July 23, 2018 (“Appeal Br.”); (3) the Examiner’s Answer mailed August 29, 2018 (“Ans.”); and (4) the Reply Brief filed September 17, 2018 (“Reply Br.”). Appeal 2019-000420 Application 15/665,754 3 Regarding independent claim 26, the Examiner finds that Stiles’ system determines whether a strainer of a component of a pool- or spa-water circulation system is clogged with debris by electronically transmitting and evaluating pressure values obtained by a pressure sensor. Final Act. 2–3. Although the Examiner acknowledges that Stiles does not transmit the pressure values to a remote location, the Examiner nonetheless takes Official Notice that this feature is well known in the art, and that transmitting Stiles’ pressure values to a remote location would have been obvious. Final Act. 3– 4. The Examiner also acknowledges that although Stiles does not mechanically connect the recited first device to the component, the Examiner cites (1) Hamza’s drain plug and pool port, and (2) Spiegel’s pool pump with multiple ports that allows for different plumbing configurations for teaching this feature. Final Act. 4–5. Based on these collective teachings, the Examiner concludes that the claim would have been obvious. Final Act. 2–5. Appellant argues that the Examiner’s reliance on Stiles is misplaced because, among other things, Stiles does not sense pressure values, let alone transmit and evaluate those values to determine that the component’s strainer is clogged with debris as claimed. Appeal Br. 9–12; Reply Br. 4–6, 8–10. According to Appellant, Stiles measures a pump motor’s power consumption to infer filter clogging—a process that is said to not evaluate transmitted pressure values obtained from a pressure sensor as claimed. See id. Appeal 2019-000420 Application 15/665,754 4 ISSUE Under § 103, has the Examiner erred in rejecting claim 26 by finding that Stiles, Spiegel, and Hamza collectively would have taught or suggested evaluating electronically-transmitted pressure values obtained from a pressure sensor to determine that a pool- or spa-water circulation system component’s strainer is clogged with debris? ANALYSIS On this record, we find the Examiner’s reliance on Stiles problematic. As noted in the Abstract, Stiles operates a safety vacuum release system (SVRS) by measuring a pump motor’s power consumption necessary to pump water and overcome losses. If controller 16 detects an obstructed inlet, the controller can quickly shut the pump down. Stiles ¶ 22; Figs. 1, 3A. In some embodiments, this detection is based only on the motor’s power consumption (e.g., the power needed to rotate the motor’s shaft), and without any additional inputs—including pressure. Id. Stiles’ controller can also detect a blocked inlet based on (1) actual power consumption; (2) current power consumption; (3) relative power consumption; (4) a dynamic counter; and/or (5) an absolute counter, the latter two counters both tied to power consumption. See id. ¶¶ 37–48. The clear import of this discussion is that Stiles’ system evaluates power consumption—not pressure—to determine clogging. That Stiles’ paragraph 22 emphasizes that no additional inputs—including pressure—are needed to achieve this end only underscores the fact that detected power consumption—not pressure—is the key factor in Stiles’ clogging determination. Id. ¶ 22. Appeal 2019-000420 Application 15/665,754 5 We reach this conclusion despite the fact that Stiles’ power- consumption-based clogging determination involves a “pressure problem” as the Examiner indicates and Appellant acknowledges. See Final Act. 3; Ans. 4; Reply Br. 4 (acknowledging that Stiles seeks to resolve a “pressure problem”). Although detecting an elevated motor power consumption would indicate a water flow blockage and, therefore, a corresponding change in pressure due to this blockage, to say that this these power consumption values are somehow equivalent to pressure values obtained by a pressure sensor as the Examiner apparently does here strains reasonable limits on this record, particularly when construing this limitation in light of the Specification. See Spec. 7 (noting that devices 26A and 26B include pressure gauges that sense and measure pressures at ports 18 and 22); see also id. at 8 (“If device 26A senses a rapid rise in vacuum (i.e. a rapid pressure decrease), for example, the strainer basket may be clogged with debris, inhibiting adequate water flow to the impeller.”) (emphasis added). As the Federal Circuit has emphasized, the broadest reasonable interpretation in light of the Specification is not whether the Specification precludes some broad reading of the claim term adopted by the Examiner. See In re Smith Int’l, Inc., 871 F.3d 1375, 1382–83 (Fed. Cir. 2017). Nor is the broadest reasonable interpretation simply one that is not inconsistent with the Specification. Id. at 1383. Rather, it is an interpretation that corresponds with what and how the inventor describes his invention in the Specification, that is, an interpretation consistent with the Specification. Id. (citing In re Suitco Surface, Inc., 603 F.3d 1255, 1259–60 (Fed. Cir. 2010)). Therefore, to interpret the recited pressure values obtained by a pressure sensor as somehow reading on Stiles’ detected motor power Appeal 2019-000420 Application 15/665,754 6 consumption values as the Examiner apparently does here is inconsistent with the Specification and, therefore, untenable on this record. The Examiner’s reliance on Stiles in this regard is, therefore, problematic on this record, and neither Spiegel nor Hamza cures this deficiency. Accordingly, we are persuaded that the Examiner erred in rejecting independent claim 26, and dependent claims 27–35 for similar reasons. Because this issue is dispositive regarding our reversing the Examiner’s rejection of these claims, we need not address Appellant’s other associated arguments. THE REJECTION OVER STILES, SPIEGEL, HAMZA, AND WIEN For the foregoing reasons, we also do not sustain the Examiner’s rejection of independent claim 36 given the Examiner’s problematic reliance on Stiles for teaching the recited pressure sensor and pressure value limitations. See Final Act. 7–9; Ans. 10–14. We reach this conclusion emphasizing that the Examiner cites Wien for a very limited purpose, namely merely to show that transmitting data wirelessly is known in the art, and that it would have been obvious to provide such wireless transmission in Stiles to extend transmission range. Final Act. 10; Ans. 12, 18. This limited reliance on Wien does not cure Stiles’ deficiencies regarding the recited pressure values, let alone two such values from first and second pressure sensors, respectively, as claim 36 requires. We do note, however, that Wien teaches a pressure sensor that measures a pipe’s internal pressure. As Wien explains, when the measured pressure (1) falls below the reference pressure when an outlet is opened, and Appeal 2019-000420 Application 15/665,754 7 (2) does not return to the reference pressure within a certain time period, the system assumes that involuntary consumption or a leak has occurred, and emits an alert. See Wien, Abstract; ¶¶ 40–41. That is, when measured pressure is below the reference pressure, the system effectively determines that water is flowing and, therefore, not obstructed. See id. Ordinarily skilled artisans could therefore reasonably infer from this correlation that when sensed pressure is at or above the reference pressure, water flow is obstructed. To the extent that Wien’s pressure-based water-flow determination could detect obstructions due to debris clogging as recited in the independent claims when considered in light of Stiles, the Examiner did not articulate such a rationale, nor will we speculate in that regard here in the first instance on appeal. We, therefore, leave that determination to the Examiner to consider after this opinion. What we can say, however, is that the Examiner’s articulated basis for the rejection is untenable on this record. Therefore, on the record before us, we are persuaded that the Examiner erred in rejecting independent claim 36.
