The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1, 3, 5-13, 15-17 and 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over Maharyta et al., US Patent 10,725,591 hereinafter referenced as Maharyta in view of Wuerstlein et al., US PGPUG 2019/0237963 hereinafter referenced as Wuerstlein.
As to claim 1, Maharyta discloses an electronic device comprising: a housing (e.g. housing 1105, fig. 11);

wherein the one or more conductors are configured to be biased at a first potential in a first mode of touch operation (at block 1035 of fig. 10, processing logic selects a second mode of capacitive touch detection from a plurality of modes of capacitive touch detection) and driven with a second stimulation signal in a second mode of touch operation (at block 1025 of fig. 10, processing logic rejects signal measurements of the second mode of capacitive touch indicating the touch in view of signal measurements of the first mode of capacitance touch detection indicating a non-touch).
Maharyta does not specifically discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation.
However, in the same endeavor, Wuerstlein discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation (e.g. sensor electrodes 20, fig. 2 and [0054], wherein the control unit 18 is correspondingly configured to detect an electrical resistance that forms between the two sensor electrodes 20 or a variable derived therefrom, and to compare it to a stored normal value that is measured between the two sensor electrodes 20 in the absence of water).
Therefore, it would have been obvious to one of ordinary skill in the art to modify the disclosure of Maharyta to further include Wuerstlein’s water sensor electrodes in order to isolate unwanted signal with intention of activating desired functions effectively.
As to claim 13, Maharyta discloses a method comprising: at an electronic device comprising a housing (e.g. housing 1105, fig. 11),

driving the one or more conductors with a second stimulation signal in a second mode of touch operation to shield one or more objects contacting the cover substrate from capacitively coupling to ground through the housing (at block 1025 of fig. 10, processing logic rejects signal measurements of the second mode of capacitive touch indicating the touch in view of signal measurements of the first mode of capacitance touch detection indicating a non-touch).
Maharyta does not specifically discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation.
However, in the same endeavor, Wuerstlein discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation (e.g. sensor electrodes 20, fig. 2 and [0054], wherein the control unit 18 is correspondingly configured to detect an electrical resistance that forms between the two sensor electrodes 20 or a variable derived therefrom, and to compare it to a stored normal value that is measured between the two sensor electrodes 20 in the absence of water).
Therefore, it would have been obvious to one of ordinary skill in the art to modify the disclosure of Maharyta to further include Wuerstlein’s water sensor electrodes in order to isolate unwanted signal with intention of activating desired functions effectively.
As to claim 17, Maharyta discloses a non-transitory computer readable storage medium storing instructions that when executed by an electronic device comprising a housing (e.g. housing 1105, fig. 11),

a touch sensor panel comprising a plurality of touch nodes that are configured to be driven with a first stimulation signal (e.g. sensor array 1125, fig. 11), and
one or more conductors disposed between the cover substrate and the housing and electrically insulated from the housing, cause the electronic device to: bias the one or more conductors at a first potential in a first mode of touch operation (at block 1035 of fig. 10, processing logic selects a second mode of capacitive touch detection from a plurality of modes of capacitive touch detection); and
drive the one or more conductors with a second stimulation signal in a second mode of touch operation to shield one or more objects contacting the cover substrate from capacitively coupling to ground through the housing (at block 1025 of fig. 10, processing logic rejects signal measurements of the second mode of capacitive touch indicating the touch in view of signal measurements of the first mode of capacitance touch detection indicating a non-touch).
Maharyta does not specifically discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation.
However, in the same endeavor, Wuerstlein discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation (e.g. sensor electrodes 20, fig. 2 and [0054], wherein the control unit 18 is correspondingly configured to detect an electrical resistance that forms between the two sensor electrodes 20 or a variable derived therefrom, and to compare it to a stored normal value that is measured between the two sensor electrodes 20 in the absence of water).

Q
103 Rejection of Claims 1, 13, and 17
On pages 3-5 of the Office Action, claim 1 was rejected as allegedly unpatentable in view of the teachings of Maharyta and Wuerstlein. Claim 1 recites, in part (emphasis added):
a touch sensor panel comprising a plurality of touch nodes that are configured to be
driven with a first stimulation signal; and
one or more conductors disposed between the cover substrate and the housing and
electrically insulated from the housing, wherein the one or more conductors are configured
to be biased at a first potential in a first mode of touch operation and driven with a second
stimulation signal in a second mode of touch operation.
Applicant respectfully submits that the proposed combination of Maharyta and Wuerstlein fails to disclose the features of claim 1.
Maharyta relates to a capacitive sense array 1125 capable of determining whether water is on the screen or not (referred to as "a characteristic of a presence of water," in the paragraph bridging columns 17 and 18). To make this determination, Maharyta's processing device 1150 is taught to first perform "a mutual capacitance touch detection scan" by driving "transmission signals using a first plurality of electrodes (e.g., row electrodes)," and designating "another plurality of electrodes" as receiving electrodes (Ibid.). Maharyta explains that if presence of water is detected, processing device 1150 can detect a touch "using a third mode of capacitance touch detection (e.g., active finger touch detection) that uses a capacitive coupling of external transmission signal 1111 to capacitive sense array 1126 through passive touch object 1115" (lines 32-41, column 17). Maharyta is able to couple external transmission signal 1111 to passive touch object 1115, particularly when passive touch object 1115 "grips or otherwise contacts housing 1105" (lines 49-52, column 17), because "external transmission signal 1111 may be coupled to conductive housing 1105" (lines 47- 49, column 17).
Elsewhere, Maharyta mentions that external transmission signal 1111 (provided by driver
1110) "may be coupled to the entire housing and the entire housing may be an external transmission electrode 1112" (lines 3-6, column 17). In other words, the principle of operation for Maharyta's touch detection relies on conductive coupling of external transmission electrode 1112 to housing 1105.
On page 4 of the Office Action, the above emphasized features of claim 1 were mapped to Maharyta's external transmission electrode 1210 of FIG. 12. External transmission electrode 1210 is described by Maharyta to be similar to external transmission electrode 1112 of FIG. 11 in both
structure and function. In terms of structure, Maharyta teaches "external transmission electrode 1210 is shown coupled to a conductive housing of electronic device 1200" (lines 20-22, column 18). In terms of function, Maharyta explains that the principle of operation for electronic device 1200 relies on the user (or "passive touch object") to be coupled to the external transmission electrode 1210 by "gripping the housing of the electronic device 1200" (lines 28-32, column 18), which is only possible when electrode 1210 is conductively coupled to the housing of device 1200.
In view of the foregoing, Applicant respectfully submits that Maharyta fails to show or suggest "one or more conductors disposed between the cover substrate and the housing and electrically insulated from the housing" (emphasis added), as recited by claim 1.
Wuerstlein is similarly deficient. Wuerstlein, cited to show "a first mode of touch
operation," discloses that sensor electrodes 20 of resistance sensor 16 "may not be electrically insulated, at least not completely, with respect to the housing interior 4" in order for an electrical contact closure to be possible (  55). In other words, Wuerstlein also suggests that sensor electrodes 20 are conductively coupled to the housing interior 4. Thus, Wuerstlein also fails to show conductors that are "electrically insulated from the housing," as required by claim 1.
To the extent that the Office Action asserts that a person of ordinary skill in the art would modify Maharyta with Wuerstlein's water sensor electrodes in order to isolate unwanted signal, the combination does not disclose "one or more conductors disposed between the cover substrate and the housing and electrically insulated from the housing." Indeed, even assuming arguendo that Wuerstlein disclosed conductors that are "electrically insulated from the housing" (and Wuerstlein does not), a person of ordinary skill in the art would not modify the external transmission electrode 1210 of Maharyta to be electrically isolated from housing of the electronic device 1200, as such a modification would render Maharyta inoperable for the above-mentioned mode of capacitive touch detection, and represents a change of the principle of operation described by Maharyta (e.g., the conductive coupling of external transmission electrode 1210 to the housing).
For at least these reasons, Maharyta and Wuerstlein fail to show or suggest the above- emphasized features of claim 1, whether taken individually or combined as proposed in the Office Action. Claim 1 is therefore patentable over Maharyta and Wuerstlein. Independent claims 13 and 17 recite similar features to claim 1, and are patentable for similar reasons.

A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.

Maharyta does not specifically discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation.
However, in the same endeavor, Wuerstlein discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation (e.g. sensor electrodes 20, fig. 2 and [0054], wherein the control unit 18 is correspondingly configured to detect an electrical resistance that forms between the two sensor electrodes 20 or a variable derived therefrom, and to compare it to a stored normal value that is measured between the two sensor electrodes 20 in the absence of water).

driving the one or more conductors with a second stimulation signal in a second mode of touch operation to shield one or more objects contacting the cover substrate from capacitively coupling to ground through the housing (at block 1025 of fig. 10, processing logic rejects signal measurements of the second mode of capacitive touch indicating the touch in view of signal measurements of the first mode of capacitance touch detection indicating a non-touch).
Maharyta does not specifically discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation.
However, in the same endeavor, Wuerstlein discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation (e.g. sensor electrodes 20, fig. 2 and [0054], wherein the control unit 18 is correspondingly configured to detect an electrical resistance that forms between the two sensor electrodes 20 or a variable derived therefrom, and to compare it to a stored normal value that is measured between the two sensor electrodes 20 in the absence of water).
Therefore, it would have been obvious to one of ordinary skill in the art to modify the disclosure of Maharyta to further include Wuerstlein’s water sensor electrodes in order to isolate unwanted signal with intention of activating desired functions effectively.
As to claim 17, Maharyta discloses a non-transitory computer readable storage medium storing instructions that when executed by an electronic device comprising a housing (e.g. housing 1105, fig. 11),

a touch sensor panel comprising a plurality of touch nodes that are configured to be driven with a first stimulation signal (e.g. sensor array 1125, fig. 11), and
one or more conductors disposed between the cover substrate and the housing and electrically insulated from the housing, cause the electronic device to: bias the one or more conductors at a first potential in a first mode of touch operation (at block 1035 of fig. 10, processing logic selects a second mode of capacitive touch detection from a plurality of modes of capacitive touch detection); and
drive the one or more conductors with a second stimulation signal in a second mode of touch operation to shield one or more objects contacting the cover substrate from capacitively coupling to ground through the housing (at block 1025 of fig. 10, processing logic rejects signal measurements of the second mode of capacitive touch indicating the touch in view of signal measurements of the first mode of capacitance touch detection indicating a non-touch).
Maharyta does not specifically discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation.
However, in the same endeavor, Wuerstlein discloses the one or more conductors are configured to be biased at a first potential in a first mode of touch operation (e.g. sensor electrodes 20, fig. 2 and [0054], wherein the control unit 18 is correspondingly configured to detect an electrical resistance that forms between the two sensor electrodes 20 or a variable derived therefrom, and to compare it to a stored normal value that is measured between the two sensor electrodes 20 in the absence of water).

Claims 2, 14 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Maharyta and Wuerstlein as applied to claims 1, 13 and 17 respectively above, and further in view of Mo et al., US Patent 10,073,562 hereinafter referenced as Mo.
As to claims 2, 14 and 18, the combination of Maharyta and Wuerstlein does not specifically disclose the second stimulation signal has a same frequency, a same phase, and a same amplitude as the first stimulation signal.
However, in the same endeavor, Mo discloses two signals having a same frequency, a same phase, and a same amplitude as the first stimulation signal (as shown in fig. 2 for example, the second signal may be a pulse signal with a same frequency, a same phase and a same amplitude as the first signal).
Therefore, it would have been obvious to one of ordinary skill in the art to modify the disclosure of Maharyta and Wuerstlein to further include Mo’s method of electrodes driving in order to isolate unwanted signal with intention of activating desired functions effectively.
Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Maharyta and Wuerstlein as applied to claim 1 above, and further in view of Kuboyama et al., US PGPUB 2017/0090599 hereinafter referenced as Kuboyama.
As to claim 4, Maharyta and Wuerstlein does not disclose the electronic device of claim 1, further comprising: one or more gaskets between the cover substrate and the housing; wherein the one or more conductors are formed in the one or more gaskets.
However, in the same endeavor, Kuboyama discloses one or more gaskets between the cover substrate and the housing; wherein the one or more conductors are formed in the one or more gaskets (gasket 6106, fig. 61).
Therefore, it would have been obvious to one of ordinary skill in the art to modify the disclosure of Maharyta and Wuerstlein to further include Kuboyama’s gaskets in order to increase the durability of the device.
Response to Arguments
Applicant's arguments filed on 10/24/2022 have been fully considered but they are not persuasive.
Applicant argues on pages 11-12 of REMARKS that ‘On page 4 of the Office Action, the above emphasized features of claim 1 were mapped to Maharyta's external transmission electrode 1210 of FIG. 12. External transmission electrode 1210 is described by Maharyta to be similar to external transmission electrode 1112 of FIG. 11 in both structure and function. In terms of structure, Maharyta teaches external transmission electrode 1210 is shown coupled to a conductive housing of electronic device 1200 (lines 20-22, column 18). In terms of function, Maharyta explains that the principle of operation for electronic device 1200 relies on the user (or passive touch object) to be coupled to the external transmission electrode 1210 by gripping the housing of the electronic device 1200 (lines 28-32, column 18), which is only possible when electrode 1210 is conductively coupled to the housing of device 1200. In view of the foregoing, Applicant respectfully submits that Maharyta fails to show or suggest one or more conductors disposed between the cover substrate and the housing and electrically insulated from the housing (emphasis added), as recited by claim 1’.
In accordance with MPEP, “USPTO personnel to give claims their broadest reasonable interpretation in light of the supporting disclosure.
For instant case, applicant does not claim a specific condition the one or more conductors are electrically insulated from the housing. Examiner pointed out the breadth of the claim and suggested to further limit the function of the one or more detectors and the claimed modes to pinpoint applicant’s invention during the interview.
Maharyta discloses a multimodal capacitance touch detection technique which are first mode of capacitance touch detection (e.g., passive touch detection) and second mode of capacitance touch detection (e.g., mutual capacitance touch detection) maybe selected in view of the presence or absence of noise signal. As shown in fig. 12, the transmission electrode 1210 is outside of the touch sensor area and not directly connected to the housing 1200 so electrical insulation between 1210 and 1200 is depending on the operating situation of the touchscreen.
Even if there is an electrical transmission between the two, it just one embodiment. In other embodiment, the housing may not be conductive, as shown in fig. 13. Therefore, the current 103 rejection will be sustained.
