ROSENER and BARRY J. LEE Appeal2014-008523 Application 12/695,486 Technology Center 2600 Before JOSEPH L. DIXON, JAMES R. HUGHES, and ERIC S. FRAHM, Administrative Patent Judges. HUGHES, Administrative Patent Judge. DECISION ON APPEAL Appeal2014-008523 Application 12/695,486 STATEMENT OF THE CASE Appellants appeal under 35 U.S.C. § 134 from a rejection of claims 1- 5, 8, 9, 12-15, and 18-20. We have jurisdiction under 35 U.S.C. § 6(b). We reverse. The invention relates to a capacitive touch sensor that includes an electrode that is directly coupled to a sensor circuit, and an additional "floating" electrode that is not mechanically connected to the sensor circuit (Spec. i-fi-120-22). Claim 1, reproduced below, is illustrative of the claimed subject matter: 1. A headset comprising: a decoupled electrically conductive material disposed within proximity of a headset surface adapted to be brought in contact with a user ear, wherein a first capacitance is formed when the headset surface is brought in contact with the user ear, wherein the headset surface comprises an insulating material disposed over the decoupled electrically conductive material, the insulating material configured to contact the user ear when the headset is in a donned state; a coupled electrically conductive material disposed in proximity to the decoupled electrically conductive material, the coupled electrically conductive material and decoupled electrically conductive material forming a capacitor having a second capacitance in series with the first capacitance; and a processor coupled to the coupled electrically conductive material adapted to receive signals from the coupled electrically conductive material to determine a measured capacitance associated with the first capacitance and the second capacitance indicating a headset donned state or a headset doffed state. 2 Appeal2014-008523 Application 12/695,486 REFERENCES The prior art relied upon by the Examiner in rejecting the claims on appeal is: Okushima et al. Philipp US 2005/0001633 Al Jan. 6, 2005 US 2007/0121959 Al May 31, 2007 REJECTION The Examiner made the following rejection: Claims 1-5, 8, 9, 12-15, and 18-20 stand rejected under 35 U.S.C § 103 (a) as being unpatentable over Philipp and Okushima. ANALYSIS The Examiner finds the combination of Philipp and Okushima teaches all the limitations of independent claim 1 except "wherein the headset surface comprises an insulating material disposed over the decoupled electrically conductive material, the insulating material configured to contact the user ear when the headset is in a donned state" (Final Act. 2--4). However, the Examiner finds this limitation "would have been obvious to try with the limited choices of placement to locate the decoupled electrode [of Okushima] behind the insulating material of the earpad 106 [of Philipp] as a matter of design choice" (Final Act. 4). Appellants contend Okushima teaches away from placing the decoupled touch electrode beneath an insulating material and that such placement is not a mere design choice (App. Br. 8-12). Philipp discloses a headset that detects user presence and includes a sense plate 160 underneath a cover 106, with a sense plate connector 154 connecting the sense plate to a charge sensing circuit 152 (Philipp, i-fi-1 57, 3 Appeal2014-008523 Application 12/695,486 59---60; Fig. 3). Okushima discloses a human body sensor with an electrode A inside a sensor case 11 and connected to a detection circuit 40, and an additional touch electrode A outside of the sensor case for receiving human contact (Okushima, i-fi-165-66; Figs. 4A and 4B). Thus, we find Philipp teaches "a coupled electrically conductive material" which is beneath an "insulating material," and Okushima teaches "a decoupled electrically conductive material" but which is not located beneath an "insulating material." Thus, as the Examiner concedes (Final Act. 4 ), the references do not specifically teach "an insulating material disposed over the decoupled electrically conductive material," as recited in claim 1, and we find such arrangement would not have been obvious. We are persuaded by Appellants' argument (App. Br. 8-12) that the Examiner erred in finding it would have been obvious to try, or a matter of design choice, to locate Okushima's touch electrode (i.e., the "decoupled electrically conductive material") beneath Philipp's headset cover 106 (i.e., the "insulating material"). The Supreme Court has explained the obvious-to- try rationale as follows: When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. KSR Int'! Co. v. Teleflex Inc., 550 U.S. 398, 412 (2007). In this case, however, the Examiner has not shown there was any design need or market pressure to solve an identified problem that would lead to the claimed invention. The Examiner asserts that locating "the decoupled electrode behind the insulating material of the earpad 106 ... would be more pleasant 4 Appeal2014-008523 Application 12/695,486 to wear for extended periods than a copper foil directly touching the ear of the user" (Final Act. 4--5). However, we find one of ordinary skill in the art would not have considered the comfort of Philipp' s headset cover 106 as answering a design need to solve a problem relating to Okushima's invention, which is drawn toward an "object detection sensor suitably used as, for example, a switch for opening and closing operations of a trunk of a vehicle" (Okushima, i-f 2). Therefore, we find it would not have been obvious to try placing Okushima's touch electrode beneath an insulating material such as Philipp' s headset cover. Further, we find it would not have been a matter of mere design choice to locate Okushima's touch electrode beneath an insulating material. The Examiner has not shown that Okushima's invention would perform equally well with the touch electrode inside the sensor case. Rather, Okushima's placement of the touch electrode outside the sensor case is part of a solution to a recognized problem, namely, weakened sensitivity in a prior art sensor with a sole electrode located inside the sensor case (see Okushima, i-f 9). To solve that problem, Okushima added the touch electrode outside the sensor case to provide the required capacitive sensitivity (Okushima, i-fi-110-13, 65). We are, therefore, constrained by the record to find the Examiner erred in rejecting independent claim 1, independent claims 8 and 14 which recite commensurate limitations, and dependent claims 2-5, 9, 12, 13, 15, and 18-20 for similar reasons. CONCLUSION The Examiner erred in rejecting claims 1-5, 8, 9, 12-15, and 18-20 under 35 U.S.C. § 103(a). 5 Appeal2014-008523 Application 12/695,486 DECISION For the above reasons, the Examiner's rejection of claims 1-5, 8, 9, 12-15, and 18-20 is reversed.
