BROWN, ARTHUR M. PESLAK, and SEAN P. O’HANLON, Administrative Patent Judges. PESLAK, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Kirk Englert et al. (“Appellants”) appeal under 35 U.S.C. § 134(a) from the Examiner’s decision rejecting claims 1—27.1 We have jurisdiction under 35 U.S.C. § 6(b). We REVERSE. 1 Appellants submit the real party in interest is Ford Global Technologies, LLC. Appeal Br. 3. Appeal 2015-005179 Application 11/622,129 THE CLAIMED SUBJECT MATTER Appellants’ invention relates to “vehicle dynamic and stability control systems” and “the mitigation of yaw oscillations experienced while trailering.” Spec. 11. Independent claim 1, reproduced below with italics added, is illustrative of the claimed subject matter. 1. A control system for a vehicle comprising: a speed sensor generating a vehicle speed signal; a sway detection sensor generating an oscillation signal in response to trailer oscillations in a predetermined frequency range for at least a predetermined period of time; at least one vehicle brake; a brake control coupled to said at least one vehicle brake and associated with at least one trailer brake; a stability control system coupled to said speed sensor, said sway detection sensor, and said brake control; and a controller coupled to said stability control system and braking at least one of said at least one vehicle brake and said at least one trailer brake and in response to said oscillation signal. REJECTIONS 1) Claims 1—10, 12—18, and 25—27 are rejected under 35 U.S.C. § 102(b) as anticipated by Offerle (US 2005/0206233 Al, published Sept. 22, 2005). 2) Claims 11 and 19 are rejected under 35 U.S.C. § 103(a) as unpatentable over Offerle and Funke (US 2002/0107627 Al, published Aug. 8, 2002). 3) Claims 20-24 are rejected under 35 U.S.C. § 103(a) as unpatentable over Funke and Offerle. 2 Appeal 2015-005179 Application 11/622,129 DISCUSSION Rejection 1 Appellants contend that Offerle does not anticipate independent claims 1 and 25 because Offerle does not disclose “generating an oscillation signal in response to trailer oscillations in a predetermined frequency range for at least a predetermined period of time.” Appeal Br. 13 (emphasis omitted). Appellants argue that the claims require “a sensor to detect sway (sway is defined in the specification to be oscillations in a certain frequency range for a specified period of time that are not the result of steering changes) and generation of an oscillation signal in response to the detection of trailer sway.” Id. at 13—14. Appellants argue that “Offerle discloses a yaw rate sensor 28 (not a sway detection sensor) that continuously generates a yaw rate output, and that is all.” Id. at 14. Appellants further argue that “Offerle’s teachings are directed to yaw rate and lateral acceleration sensors that detect when a vehicle is turning.” Id. Appellants continue that “[tjhere is no disclosure, teaching or suggestion in Offerle to detect signals that are representative of oscillations in a certain frequency range for a specified period of time as claimed in the present invention.” Id. The Examiner responds that, in a prior Board decision, it was determined that Offerle discloses “a sway detection sensor generating an oscillation signal.” Ans. 3 (citing Board decision mailed December 13, 3 Appeal 2015-005179 Application 11/622,129 2013).2 With respect to the portion of the claim limitation italicized above, the Examiner states: There is no particular range or particular period of time recited in the claims. There is no restriction on the range or the time. This claimed feature would allow any range or any period of time. Since the range and period of time have not been restricted, any range and any time period would be acceptable to meet this claimed feature. As such, Offerle . . . meet[s] this claimed feature. Id. For the following reasons, we do not sustain this rejection. Appellants’ Specification describes that during towing of a trailer, “a vehicle-trailer combination has a physical phenomenon . . . such that at a certain speed lateral disturbances to the trailer may cause divergent trailer yaw oscillations. . . . The trailer yaw oscillations may develop into an unstable situation.” Spec. 14. The Specification further provides that sway oscillations occur “in a certain frequency range, such as between 0.5-1.5Hz, which occur for a specific period of time and that are not caused by steering changes.” Id. 143. Based on this disclosure, we determine that one of ordinary skill in the art would understand the term “trailer oscillations” to mean oscillations not caused by steering changes, but by lateral disturbances to the trailer during travel. Although we appreciate the Examiner’s reference to Offerle’s yaw rate sensor, Offerle discloses that “in straight line driving, the vehicle yaw stability control usually does not activate.” Offerle 1132; see also id. Fig. 2 In that Decision, it was stated that a yaw rate sensor “may constitute a sway detection sensor and generate oscillation signals.” 12/13/13 Dec. at 4 (emphasis added). 4 Appeal 2015-005179 Application 11/622,129 19 (yaw rate comparison only applied at step 265 if vehicle is “Turning Forward” at step 264.). Offerle provides “a control system to enhance the traditional yaw stability control upon the detection of the unstable trailering during a turning.” Id. 1134. The Examiner has not, however, directed us to any disclosure in Offerle where the yaw rate sensor is used to determine trailer oscillations when the vehicle is travelling in a forward direction, nor has the Examiner directed us to any disclosure in Offerle of frequency of oscillations or time period for oscillations. The Examiner has, thus, not adequately explained how Offerle’s yaw rate sensor generates “an oscillation signal in response to trailer oscillations in a predetermined frequency range for at least a predetermined period of time” in view of our construction of the term “trailer oscillations.” We also do not agree with the Examiner that any frequency range or time period will meet the claim limitations because the frequency range and predetermined time period relate to those that result in “trailer oscillations.” Consequently, the Examiner has not established by a preponderance of the evidence that Offerle discloses the “sway detection sensor” recited in claim 1, or the step of “generating an oscillating signal indicative of a trailer swaying . . .” recited in claim 25. We, thus, do not sustain the rejection of claims 1 and 25 and claims 2—10 and 12—18 which depend from claim 1 and claims 26 and 27 which depend from claim 25. Rejection 2 Claims 11 and 19 depend from claim 1. Appeal Br. 30-31 (Claims App.). The Examiner rejects claims 11 and 19 as unpatentable over Offerle and additional disclosure from Funke. Final Act. 4. The Examiner does not, however, rely on the additional disclosure from Funke to cure the deficiencies in Offerle with regard to claim 1, as discussed above. Id. 5 Appeal 2015-005179 Application 11/622,129 Therefore, we do not sustain the rejection of claims 11 and 19 for the same reasons stated in connection with claim 1. Rejection 3 Regarding claim 20, the Examiner finds that Funke discloses “a sway detection sensor 638 generating an oscillation signal in response to detecting trailer oscillations within a predetermined frequency range for at least a predetermined period of time.” Final Act. 5. Appellants contend that Funke does not disclose the claimed sway detection sensor but, rather, discloses a string potentiometer 638 “that measures an angle between the trailer and the vehicle known as the hitch angle.” Appeal Br. 24. Appellants argue that Funke’s string potentiometer provides “an instantaneous articulation angle between the vehicle and the trailer” but does not “generate an oscillation signal” as required in claim 20. Id. The Examiner provides the same response as for claim 1. Ans. 3—A. The Examiner has not directed us any to any disclosure in Funke of frequency of oscillations or time period for the oscillations. As also with claim 1, the Examiner has, thus, not adequately explained how Funke’s string potentiometer generates “an oscillation signal in response to detecting trailer oscillations within a predetermined frequency range for at least a predetermined period of time.” We also do not agree with the Examiner that any frequency range or time period meet the claim limitations because the frequency range and predetermined time period are related to those that result in “trailer oscillations.” Consequently, the Examiner has not established by a preponderance of the evidence that Funke discloses the “sway detection sensor” recited in claim 20. Further, the Examiner does not rely on Offerle in this rejection for disclosure of the sway detection sensor. 6 Appeal 2015-005179 Application 11/622,129 Final Act. 5. We, thus, do not sustain the rejection of claim 20 or the rejection of claims 21—24 which depend from claim 20. DECISION The Examiner’s decision rejecting claims 1—27 is reversed.
