SAADAT, ERIC B. CHEN, and CARLL. SILVERMAN, Administrative Patent Judges. CHEN, Administrative Patent Judge. DECISION ON APPEAL Appeal2018-003484 Application 14/256,849 STATEMENT OF THE CASE Pursuant to 35 U.S.C. § 134(a), Appellant1 appeals from the Examiner's decision to reject claims 9, 11-17, and 19. Claim 10 has been cancelled, and claims 1-8 and 18 have been withdrawn from consideration. An oral hearing was held on November 5, 2019. The record will include a written transcript of the oral hearing. We have jurisdiction under 35 U.S.C. § 6(b ). We REVERSE. CLAIMED SUBJECT MATTER The claims are directed to integrated touch screens, including drive lines formed of grouped-together circuit elements of a thin film transistor (TFT) layer, sense lines formed between a color filter layer, and a material layer that modifies or generates light. (Abstract.) Claim 9, reproduced below, is illustrative of the claimed subject matter, with disputed limitations in italics: 9. An organic light emitting diode touch sensitive device including a plurality of display pixels, the device comprising: an encapsulation layer; a cathode layer, the cathode layer containing circuit elements that can be configured to operate as drive lines in a mutual capacitance touch sensor during a touch mode of the device and as display hardware during a display mode of the device; an anode layer, the anode layer containing circuit elements that can be configured to be stimulated when the drive 1 We use the word "Appellant" to refer to "Applicant" as defined in 37 C.F.R. § 1.42(a).

OPINION § 103 Rejection-Hwang and Yousefpor We are persuaded by Appellant's arguments (Appeal Br. 9-11) that the combination of Hwang and Yousefpor would not have rendered obvious independent claim 9, which includes the limitation "an anode layer, the 3 Appeal2018-003484 Application 14/256,849 anode layer containing circuit elements that can be configured to be stimulated when the drive lines of the cathode layer are stimulated during the touch mode of the device." The Examiner found that anode 103 of Hwang (i.e., main part 1031, first conducting part 1032, and second conducting part 1033) and cathode 101 of Hwang, such that a capacitance is formed between anode 103 and cathode 101, collectively correspond to the limitation "the anode layer containing circuit elements that can be configured to be stimulated when the drive lines of the cathode layer are stimulated during the touch mode of the device." (Final Act. 5-6; see also Ans. 10.) We do not agree with the Examiner's findings. Independent claim 1 recites "the anode layer containing circuit elements that can be configured to be stimulated when the drive lines of the cathode layer are stimulated during the touch mode of the device" ( emphases added). One relevant plain meaning for "stimulate" is "to excite to activity." MERRIAM-WEBSTER'S COLLEGIATE DICTIONARY 1055 (10th ed. 1999). Moreover, Appellants' Specification, in reference to Figures IA-IC, discloses that "[d]uring operation, the rows can be stimulated with an AC waveform." (Spec. ,r 19 (emphasis added).) In addition, Appellant's Specification discloses the following: In other examples, the drive lines can be simultaneously stimulated. FIG. 11 illustrates an example stimulation of touch sensor panel according to examples of the disclosure. In particular, FIG. 11 illustrates signal paths of drive signals through rows 1104 and sense signals through columns 1106 of touch sensor panel 1124. 4 Appeal2018-003484 Application 14/256,849 (Id. ,r 42.) Thus, under the broadest reasonable interpretation consistent with the Specification, we interpret "stimulated" as applying an electrical signal (e.g., AC waveform) "to excite to activity." Hwang relates to a display apparatus, in particular, "integrating[] the image display function and the touch sense function." (Abstract.) Figure 5B of Hwang illustrates one embodiment of a display apparatus, which includes cathode layer 101, OLED ( organic light emitting diode) layer 102, anode layer 103, and thin film transistor array layer 104. Hwang explains that "anode layer 103 comprises a main part 1031, a first conducting part 1032 and a second conducting part 1033." (i-f 36.) Hwang further explains that "as the touch sense period initializing, a capacitance is formed between the first conductor block 1011 [ of cathode layer 101] and the anode layer 103 and a capacitance is also formed between the second conductor block 1012 [ of cathode layer 101] and the anode layer 103." (i-f 3 7.) Although the Examiner cited to: (i) main part 1031, first conducting part 1032, and second conducting part 1033 of anode 103; and (ii) the capacitance formed between cathode layer 101 and anode layer 103 during the touch sense period, the Examiner has provided insufficient evidence to support a finding that Hwang teaches the limitation "the anode layer containing circuit elements that can be configured to be stimulated when the drive lines of the cathode layer are stimulated during the touch mode of the device." In particular, although the Examiner interpreted "stimulated" as the capacitance formed between cathode layer 101 and anode layer 103 (see Ans. 10), such interpretation is inconsistent with the Specification, because as discussed previously, the plain meaning of the term "stimulated" is applying an electrical signal "to excite to activity." 5 Appeal2018-003484 Application 14/256,849 Thus, on this record, the Examiner has not shown that Hwang teaches the limitation "the anode layer containing circuit elements that can be configured to be stimulated when the drive lines of the cathode layer are stimulated during the touch mode of the device." In addition, Y ousefpor does not cure the above noted deficiencies of Hwang. Thus, we are persuaded by Appellants' arguments, as follows: Fig. 5A of Hwang ... shows that Hwang merely discloses that a capacitance is formed between the first conductor block 1011 (also referred to as the first cathode block 1011) and the anode layer 103 and a capacitance is formed between the second conductor block 1012 (also referred to as the second cathode block 1012) and the anode layer 103. (Appeal Br. 9--10.) A capacitance formed between two electrodes does not imply that one electrode contains circuit elements that are used as drive lines and the other electrode contains circuit elements that can be stimulated to cancel a noisy DC current flowing between these two electrodes when the drive lines are stimulated. (Id. at 10-11.) Accordingly, we do not sustain the rejection of independent claim 9 under 35 U.S.C. § 103. Claims 11-14 depend from independent claim 9. We do not sustain the rejection of claims 11-14 under 35 U.S.C. § 103 for the same reasons discussed with respect to independent claim 9. § 103 Rejection-Hwang and Kuo We do not sustain the rejection of claims 9, 11, 12 and 15 under 35 U.S.C. § 103 as unpatentable over Hwang and Kuo for the same reasons discussed with respect to rejection of claims 9 and 11-14 under 35 U.S.C. 6 Appeal2018-003484 Application 14/256,849 § 103 as unpatentable over Hwang and Yousefpor. Moreover, Kuo does not cure the above noted deficiencies of Hwang. § 103 Rejection-Hwang and Krah We do not sustain the rejection of claims 9, 11, 16, and 17 under 35 U.S.C. § 103 as unpatentable over Hwang and Krah for the same reasons discussed with respect to rejection of claims 9 and 11-14 under 35 U.S.C. § 103 as unpatentable over Hwang and Yousefpor. Moreover, Krah does not cure the above noted deficiencies of Hwang. § 103 Rejection-Hwang, Krah, and Jobs Claim 19 depend from claim 9. Jobs was cited by the Examiner for teaching the additional features of claim 19. (Final Act. 26-27.) However, the Examiner's application of Jobs does not cure the above noted deficiencies of Hwang and Krah. Moreover, Jobs does not cure the above noted deficiencies of Hwang.
