ADAMS, RICHARD J. SMITH, and RACHEL H. TOWNSEND, Administrative Patent Judges. SMITH, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134 involving claims to a physiological sensor (or associated light sheet), such as a sensor to measure oxygen saturation of blood and tissue. We have jurisdiction under 35 U.S.C. § 6(b). We reverse. 1 According to Appellants, the real parties in interest are COVIDIEN LP, and its parent company, Medtronic PLC. (Appeal Br. 1.) Appeal 2016-003217 Application 12/832,346 STATEMENT OF THE CASE Claims on Appeal Claims 1, 3—12, 14—16, and 20 are on appeal. (Listing of Claims, Appeal Br. 13—17.) Claim 1 is illustrative and reads as follows: 1. A sensor comprising: a sensor pad configured to be disposed on a portion of a patient’s body; and a light sheet disposed on the sensor pad and having a first substrate and a second substrate at least partially spaced from one another, wherein the light sheet includes a light source and a light detector and wherein the light source and the light detector are disposed between the first and second substrates such that the light source is configured to emit near-infrared light through the first substrate into the patient’s body and the light detector is configured to detect near-infrared light reflected from the patient’s body through the first substrate, wherein the first substrate includes a first layer having a conductive pattern and a second layer having a conductive pattern and wherein the first layer and the second layer are separated by a non-conductive spacer material, wherein the light source and light detector are both electrically connected between the second substrate and the second layer of the first substrate. Examiner’s Rejections 1. Claims 1, 3, 4, 6—12, and 14 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Hicks2 and Malita.3 (Ans. 2—5.) 2. Claims 5, 15, 16, and 20 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Hicks, Malita, and Medina.4 (Id. at 6—8.) 2 Hicks et al., US 6,745,061 Bl, issued June 1, 2004 (“Hicks”). 3 Malita, US 5,388,357, issued Feb. 14, 1995. 4 Medina, US 2009/0323067 Al, pub. Dec. 31, 2009. 2 Appeal 2016-003217 Application 12/832,346 DISCUSSION Rejection No. 1 Issue Whether a preponderance of evidence of record supports the Examiner’s rejection under 35 U.S.C. § 103(a). Analysis The Examiner’s rejection relies on a sensor embodiment in Hicks that includes a light sheet having first and second substrates, with a light source (LEDs) and light detector disposed between the substrates. (Ans. 2—3.) That sensor embodiment is illustrated by Fig. 12 of Hicks below, wherein 80 and 94 identify the substrates, and 72 identifies electrical traces for connecting the active components, such as LED 40. (Hicks col. 12,11. 30-41.) Figure 12 above illustrates a plan view of an oximetry sensor. 3 Appeal 2016-003217 Application 12/832,346 The Examiner finds that Hicks discloses all of the elements of independent claims 1 and 12, except for wherein the first substrate includes a first and second layer having a conductive pattern and wherein the first layer and the second layer are separated by a non-conductive spacer material and wherein the light source and light detector are both electrically connected between the second substrate and the second layer of the first substrate. (Ans. 3.) The Examiner thus combines Hicks with Malita,5 finding that: Malita discloses a diode connected] in series with a capacitor; the diode is an LED light source; the capacitor is the first substrate with conductive layers and non-conductive spacer between conductive layers; the two plates are conductive layers and the dielectric between the plates is non-conductive spacer; the two lines with space in between. {Id. at 4 (emphasis added).) The Examiner references Figures 7A—C (below) of Malita in support of that finding, showing capacitor 54 (FIG. 7 A) and LEDs 32: FIG. 7A 56'^ffcsVV\, FIG. 7B 32f ft32 FIG. 7C C HF R fit Figures 7A, 7B, and 7C above illustrate electrical circuit diagrams. Based on those findings, the Examiner concludes that: It would have been obvious to one of ordinary skill in the art at the time of the invention to modify Hicks to include wherein 5 Malita is directed to a kit using LED units for retrofitting illuminated signs, such as a conventional EXIT sign. (See Malita Title and Abstract.) 4 Appeal 2016-003217 Application 12/832,346 the first substrate includes a first and second layer having a conductive pattern and wherein the first layer and the second layer are separated by a non-conductive spacer material and wherein the LED/diode are both electrically connected between the second substrate and the second layer of the first substrate as taught by Malita because this allow[s] control of voltage for the diodes to prevent overload [of] the diodes. (Ans. 4 (citing Malita col. 7,11. 35—47).) Thus, according to the Examiner, “Hicks in view of Malita would replace Hicks[’] first substrate with Malita’s substrate (Figs. 7A—C, the top line is the first conductive layer, the bottom line is the second conductive layer) which has first and second layer with conductive pattern.” (Ans. 12.) Appellants argue that “[i]t would not be possible for a person of ordinary skill in the art to simply replace Hicks’ ‘clear substrate’ 80 with Malita’s conventional capacitor 54, as urged by the Examiner.”6 (Reply Br. 3.) For example, Appellants argue that: Malita’s conventional capacitor would need to be reconfigured so that the first and second layers and the dielectric therebetween all were transparent or sufficiently translucent so that “near-infrared light[”] could be transmitted “through the first substrate into the patient’s body ...”, which is not disclosed by Malita’s conventional capacitor 54. (Reply Br. 4.) Appellants also argue that Hicks teaches connecting light sources and the light detector through electrical traces that are disposed on opposing 6 Appellants contend that the Examiner’s reference to the first substrate of Hicks refers to clear substrate 80 rather than substrate 94. (Reply Br. 3, n. 1.) On this record, it is unclear whether the Examiner is referring to a particular substrate in Hicks in making the proposed replacement, but all of the independent claims (1, 12, and 16) require that the light source be “configured to emit near-infrared light through the first substrate.” (Id.) 5 Appeal 2016-003217 Application 12/832,346 inner surfaces of the substrates, and that the Examiner’s proposed modification “would require that Hicks’ electrical connections be made through the newly-constructed ‘first substrate,’ integrating the ‘first substrate’ itself as part of the electrical path.” {Id. at 4—5.) But, according to Appellants, the electrical path taught by Hicks is the electrical traces disposed on inner surfaces of the substrates, and that “‘clear substrate’ 80 is a carrier or mounting surface for electrical traces 70-76; it is not itself part of the electrical path.” {Id. at 5.) Appellants argue further that: The Examiner does not offer any reason why it would have been obvious to a person skilled in the art to make significant structural and electrical modifications to Hicks when the purported goal of preventing voltage overload of the diodes could be accomplished simply by adding a conventional capacitor like that shown in Malita within the existing electrical path. {Id. at 5.) We find that Appellants have the better position. A prima facie case for obviousness “requires a suggestion of all limitations in a claim,” CFMT, Inc. v. Yieldup Inti Corp., 349 F.3d 1333, 1342 (Fed. Cir. 2003) and “a reason that would have prompted a person of ordinary skill in the relevant field to combine the elements in the way the claimed new invention does” KSRIntI Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). Here, the Examiner’s proposed combination is based on replacing Hicks’ first substrate with a capacitor as taught by Malita. (See Ans. 12.) Moreover, as illustrated by Figure 12 above, the text of Hicks relied upon by the Examiner describes “a sensor where the electrical traces ... as well as the active sensor components are sandwiched between the first and second 6 Appeal 2016-003217 Application 12/832,346 substrates and are thereby protected from the environment.” (Ans. 3; see also Hicks col. 5,11. 10—13.) In our view, the Examiner has not shown how or why a person of ordinary skill in the art would replace one of the Hicks substrates with a capacitor. (See Reply Br. 4—5.) As Appellants point out, such a combination would require significant structural and electrical modifications to Hicks. {Id. at 5.) Moreover, the Examiner does not persuasively explain how, after such a proposed modification, the light sheet would still include a light source that (1) is “configured to emit near-infrared light through the first substrate,” (i.e., through the capacitor), and (2) is electrically connected between the second substrate and the second layer of the first substrate, as required by claims 1 and 12. (Ans. 3.) Accordingly, because the Examiner has failed to present a prima facie case of obviousness, the rejection of independent claims 1 and 12 is reversed. Dependent claims 3, 4, 6—11, and 14 stand with claims 1 and 12. Rejection No. 2 Independent claim 16 includes limitations similar to claims 1 and 12 (Appeal Br. 16), and Appellants rely on the same arguments advanced in connection with Rejection No. 1. (Appeal Br. 11—12.) Accordingly, claim 16 is nonobvious for the reasons set forth above regarding claims 1 and 12. Claims 5, 15, and 20 are nonobvious because the respective claims on which they depend are nonobvious. See In re Fine, 837 F.2d 1071, 1076 (Fed. Cir. 1988). Accordingly, the rejection of claims 5, 15, 16, and 20 is reversed. 7 Appeal 2016-003217 Application 12/832,346 Conclusions of Law A preponderance of evidence of record fails to support the Examiner’s rejection of claims 1 and 12 for obviousness. Dependent claims 3, 4, 6—11, and 14 stand with claims 1 and 12. A preponderance of evidence of record fails to support the Examiner’s rejection of claims 5, 15, 16, and 20 for obviousness.
