`
`VI. LEVEL OF ORDINARY SKILL IN THE ART
`A person of ordinary skill in the art at the time of the alleged invention of
`
`the ’183 patent would have had at least a B.S. degree in electrical engineering, or
`
`equivalent thereof, and at least two to three years of experience in the relevant
`
`field, which includes touch systems technology. (Ex. 1002 at ¶ 19.)
`
`VII. OVERVIEW OF THE PRIOR ART & ’183 PATENT
`A. Technology Background
`The prior art cited in this petition and the ’183 patent generally relate to
`
`
`
`capacitive touch sensors. (Ex. 1002 at ¶¶ 26, 27.) The operation of capacitive
`
`3
`
`
`
`Petition for Inter Partes Review
`Patent No. 5,796,183
`touch sensors was well understood at the time of the alleged invention of the ’183
`
`patent. (Id.) In a capacitive touch sensor that utilizes the phenomenon of “self-
`
`capacitance” as its detection mechanism, when a user touches the self-capacitance
`
`sensor, she creates an additional path to ground, thereby increasing the total
`
`capacitance between the electrode and ground. (Id.; Ex. 1011 at 10.) This results
`
`in an increase in current for the sensor electrode that can be measured to determine
`
`whether the touch sensor has been touched by a user. (Ex. 1002 at ¶ 27.) As
`
`discussed in detail in the sections to follow, the ’183 patent and the prior art (e.g.,
`
`Ingraham I), disclose such self-capacitance touch sensor features. (Id.)
`
`The ’183 Patent
`
`B.
`The ’183 patent relates to a capacitive responsive electronic switching
`
`circuit. (Ex. 1001 at Abstract; Ex. 1002 at ¶¶ 20-24.) Figure 4 of the ’183 patent
`
`describes “a block diagram of a capacitive responsive electronic switching circuit.”
`
`(Ex. 1001 at 7:22-24.) The circuit includes an oscillator providing a periodic
`
`output signal, an input touch terminal for an operator to provide an input by
`
`proximity or touch, and a touch circuit that receives the output signal from the
`
`oscillator. (Id. at Fig. 4, 12:6-28.) As disclosed in connection with Figure 8 (touch
`
`circuit), when there is no touch by the operator at the touch pad, transistor 410 does
`
`not conduct. (Id. at 15:29-47.) When there is a touch at the touch pad, the increase
`
`in capacitance at the touch pad causes transistor 410 to conduct, which then causes
`
`4
`
`
`
`Petition for Inter Partes Review
`Patent No. 5,796,183
`Schmitt Trigger 420 to emit a signal indicating a touch is present. (Id. at 15:37-
`
`47.)
`
`C. The Prosecution History of the ’183 Patent
`The ’183 patent issued from U.S. Patent Application No. 08/601,268 on
`
`August 18, 1998. (See generally Ex. 1004.) Nearly fifteen years after the ’183
`
`patent issued, and after development of touch screen smartphones and tablets by
`
`Petitioner and other manufacturers, Patent Owner twice sought reexamination of
`
`the ’183 patent to add 85 new claims. (See generally Ex. 1005, 1006.) Patent
`
`Owner now pursues litigation against Petitioner on those new claims.
`
`Among the references relied upon in this Petition, Caldwell and Wheeler
`
`were never considered by
`
`the Patent Office during prosecution or
`
`the
`
`reexaminations. (See generally Exs. 1009, 1015; see also id. at Ex. 1001 at
`
`References Cited.) The primary reference (Ingraham I) for the proposed grounds
`
`in this petition was considered by the Patent Office during prosecution and a
`
`secondary reference (Gerpheide) was brought to the Examiner’s attention in the
`
`second re-examination. But Petitioner presents Ingraham I and Gerpheide in a
`
`new light never considered by the Office. (See infra Section IX.) Moreover,
`
`Petitioner presents testimony from Dr. Vivek Subramanian (Ex. 1002), who
`
`confirms that the relevant teachings of Ingraham I in combination with Caldwell,
`
`Gerpheide, and Wheeler discloses what is claimed by the challenged claims of the
`
`5
`
`
`
`Petition for Inter Partes Review
`Patent No. 5,796,183
`’183 patent. (See Ex. 1002.) As such, consideration of Ingraham I and Gerpheide
`
`by the Patent Office should not preclude the Office from considering and adopting
`
`the grounds in this petition that involve these references.
`
`D.
`Ingraham I
`Ingraham I (Ex. 1007) discloses a “capacity response keyboard.” (Ex. 1007,
`
`Abstract; Ex. 1002 at ¶ 28.) The keyboard consists of “capacity responsive
`
`switches” “that respond to the change in capacity from a user touching a surface
`
`portion of the switch.” (Ex. 1007 at 1:5-9.) Ingraham I discloses a capacity
`
`responsive keyboard system 10, which includes a touch plate assembly 12 (Fig. 2)
`
`and a control circuit 14 (Fig. 3) connected with touch plate assembly 12. (Id. at
`
`Figs. 2, 3, 2:28-35.) The capacitive responsive keyboard system 10 controls
`
`actuation of a “load 69 such as an electric motor.” (Id. at Fig. 3, 2:32-35.) Touch
`
`plate assembly 12 includes “includes a substrate 16 on which a plurality of
`
`electrically conductive plate members 18 are mounted on one surface thereof.”
`
`(Id. at 2:40-43.) The touch pad assembly 12 includes multiple “input portions 13”
`
`and an indicia layer 30 adhering to the back surface 32 of dielectric member 26 to
`
`“provide an indication of the function of each input portion 13.” (Id. at Figs. 1, 2,
`
`2:64-67.) One of ordinary skill in the art would have understood that a single input
`
`portion 13 (e.g., the red oval in demonstrative A below) constitutes the
`
`combination of a portion of the dielectric member 26, indicia 30, a transmission
`
`6
`
`
`
`member 18, plate member 18.” (Ex. 1002 at ¶ 29 .)
`
`Petition for Inter Partes Review
`Patent No. 5,796,183
`
`
`
`(Ex. 1007 at Figs. 1, 2, (annotated); Ex. 1002 at ¶ 29.)
`
`When the user touches an input portion 13 by touching the “outwardly-
`
`facing surface 34 of dielectric member 26, the capacity-to-ground for the
`
`corresponding plate member 18 is increased substantially, as illustrated by
`
`capacitor 42 in FIG. 3.” (Ex. 1007 at 3:1-6, 3:21-47.) This increase in the
`
`capacitance is detected by a touch sensing circuit (annotated in blue in
`
`demonstrative B below), which accordingly provides an output signal on line 57 to
`
`microcomputer 80. (Id. at Fig. 3; Ex. 1002 at ¶ 30.)
`
`7
`
`
`
`Petition for Inter Partes Review
`Patent No. 5,796,183
`
`
`
`(Ex. 1007 at Fig. 3 (annotated); Ex. 1002 at ¶ 30.) Each of the touch sensing
`
`circuits including the input portion 13 receives an AC signal (annotated in green
`
`above) from the 115V AC power source. The above-described touch detection
`
`mechanism is very similar to the touch detection mechanism disclosed in the ’183
`
`patent. (Ex. 1002 at ¶¶ 31-33; Ex. 1001 at 5:43-45.)
`
`E.
`Ingraham II and Ingraham III
`Ingraham I builds on prior patents (Ingraham II and Ingraham III) by the
`
`same inventor. (Ex. 1007 at 1:39-54.) For instance, Ingraham I incorporates by
`
`reference certain disclosure from Ingraham II. (Id. at 3:21-24.) “To incorporate
`
`material by reference, the host document must identify with detailed particularity
`
`8
`
`
`
`Petition for Inter Partes Review
`Patent No. 5,796,183
`what specific material it incorporates and clearly indicate where that material is
`
`found in the various documents.” Advanced Display Sys., Inc. v. Kent State Univ.,
`
`212 F.3d 1272, 1282–83 (Fed. Cir. 2000). Whether a patent describes material to
`
`be incorporated by reference with sufficient particularity is assessed from the
`
`perspective of a person of ordinary skill in the art. Id. at 1283. Moreover, citation
`
`to a specific page (e.g., by page and line number) is not necessary so long as one of
`
`ordinary skill would have understood the material specifically incorporated by
`
`reference. See e.g., Harari v. Lee, 656 F.3d 1331 (Fed. Cir. 2011) (statement that
`
`“the disclosures” of two identified applications “are hereby incorporated by
`
`reference” was sufficient to incorporate the applications in their entirety).
`
`Here, while Ingraham I discloses a control circuit 14 (see Fig. 3), it does not
`
`provide a detailed explanation about the components of circuit 14. (Ex. 1007 at
`
`3:21-24.) Instead, Ingraham I incorporates by reference the teachings of Ingraham
`
`II for purposes of control circuit 14. (Id., “A detailed description of control circuit
`
`14 is provided in U.S. Pat. No. 4,731,548, issued Mar. 15, 1988 to Ronald
`
`Ingraham, the disclosure of which is hereby incorporated herein by reference.”)
`
`One of ordinary skill in the art would have understood that Ingraham I identifies
`
`with particularity and specifically incorporates by reference the disclosure in
`
`Ingraham II regarding control circuit 14. (Ex. 1002 at ¶ 34.) Given that Ingraham
`
`I specifically calls out control circuit 14, one of ordinary skill in the art would have
`
`9
`
`
`
`Petition for Inter Partes Review
`Patent No. 5,796,183
`understood that the disclosure in at least columns 2, 3 and figure 1 of Ingraham II
`
`relating to the control circuit 14 is incorporated by reference in Ingraham I. (Id.)
`
`While both Ingraham I and Ingraham II derive their oscillating input signal for the
`
`touch sensing circuits and input portions 13 from a 115 VAC power line, Ingraham
`
`III adapts the same touch sensing circuit to a portable system (e.g., for an
`
`automobile, airplane) by providing a dedicated oscillator circuit that operates on a
`
`DC supply and provides an oscillating signal to the touch terminals and the touch
`
`sensing circuitry. (Ex. 1002 at ¶¶ 35-37; compare Ex. 1007 at 3:30-47, with Ex.
`
`1008 at Fig. 1, 2:39-3:15 and Ex. 1010 at Fig. 1, 2:48-3:10.) (Ex. 1010 at 1:32-44,
`
`1:53-55, 2:21-60.)
`
`Caldwell
`
`F.
`Caldwell discloses a touch panel that includes a touch sensor that detects
`
`user contact. (Ex. 1002 at ¶ 38; Ex. 1009 at 1:6-9.) The configuration of an
`
`individual pad is described with reference to figures 1 and 2. (Ex. 1009 at Figs. 1,
`
`2, 3:24-29.) Dielectric substrate 10 has a front surface 12, where a user contacts
`
`the touch pad, and a back surface 14 where center electrode 16 and outer electrode
`
`18 are formed. (Id. at 4:11-19, Figs. 1, 2.) A strobe line 22 is connected to the
`
`outer electrode 18 to provide a strobe signal, which is an oscillating square wave
`
`generated by an oscillator 30. (Id. at 4:39-51, 6:40-53, Figs. 1, 12.) A sense
`
`electrode 24 is also provided for every touch pad for carrying a detection signal
`

`from the touch pad to the detection circuitry. (Id. at 5:3-6, Fig. 1.) Figure 6 shows
`
`a matrix of touch pads that constitutes a touch panel. (Id. at 5:60-61.) The system
`
`of Caldwell (see Fig. 12) sequentially monitors each of the touch pads in this
`
`matrix by providing a strobe signal on strobe electrodes 22 to a row (or column) of
`
`touch pads and then sequentially selecting columns (or rows) of sense electrodes
`
`24 to sense the signal output from the touch pad (see Fig. 5). (Id. at 6:40-63; see
`
`id. at Fig. 6; Ex. 1002 at ¶¶ 39-40.)
`
`VIII. CLAIM CONSTRUCTION
`The ’183 patent expired on January 31, 2016. Accordingly, the claims of the
`
`’183 patent should be construed under the standard set forth in Phillips v. AWH
`
`Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). See, e.g., Square Inc. v. J. Carl
`
`Cooper, IPR2014-00156, Paper No. 38 at 7 (May 14, 2015) (citing In re Rambus,
`
`Inc., 694 F.3d 42, 46 (Fed. Cir. 2012)). Under Phillips, claim terms are given their
`
`ordinary and customary meanings, as would be understood by a person of ordinary
`
`skill in the art, at the time of the invention, having taken into consideration the
`
`language of the claims, the specification, and the prosecution history of record.
`
`See, e.g., Cisco Systems, Inc., v. AIP Acquisition, LLC, IPR2014-00247, Paper No.
`
`20 at 2-3 (July 10, 2014). The Board, however, only construes the claims when
`
`necessary to resolve the underlying controversy. Toyota Motor Corp. v. Cellport

`
`In the corresponding district court litigation, Petitioner and Patent Owner
`
`proposed constructions for the terms listed below. Because as discussed below, the
`
`prior art discloses the claimed features under either party’s construction, the Board
`
`need not construe these terms in this proceeding.
`
`Should the Board need to
`
`construe one of the below list terms,
`
`it should adopt Petitioner’s constructions
`
`because they are consistent with the language of the claims, specification, and
`
`prosecution history under Phillips.

`IX. DETAILED EXPLANATION OF GROUNDS
`A. Ground 1: Ingraham I, Caldwell, and Gerpheide Render Obvious
`Claims 37-41, 43, 45, 61, 64-67, 69, 83, 85, 86, 88, 90, 91, 94, 96, 97,
`99, 101, and 102
`1.
`Claim 37
`“A capacitive responsive electronic switching circuit for a controlled device
`comprising:”
`Ingraham I discloses this feature. (Ex. 1002 at ¶¶ 41-42.) For example,
`
`a)
`
`Ingraham I discloses that “[t]he invention is especially adapted for a keyboard
`
`made up of a plurality of such capacity responsive switches.” (Ex. 1007 at 1:5-9,
`
`emphasis added.) The keyboard of capacity responsive switches controls a device
`
`such as an electric motor. (Id. at 2:32-35, 3:45-47.) (See also discussion above in
`
`Section VII.D; citations and analysis below for the remaining elements of this
`
`claim.)
`
`b)
`
`“an oscillator providing a periodic output signal having a predefined
`frequency,”
`
`Ingraham I and Caldwell discloses this feature. (Ex. 1002 at ¶ 43.) As
`
`illustrated in Fig. 3, Ingraham I discloses a 115V AC power source. (Ex. 1007 at
`
`Fig. 3.) One of ordinary skill in the art would have understood that the 115 VAC
`
`power source is a 115 V 60 Hz AC power source derived from the power line
`
`providing electricity to the unit housing the device. (Ex. 1002 at ¶ 43.) Indeed, the
`
`15
`
`
`
`Petition for Inter Partes Review
`Patent No. 5,796,183
`incorporated disclosure from Ingraham II (see Section VII.E) regarding the control
`
`circuit14 shows that the 115 VAC signal is a 60 Hz AC power signal. (See e.g.,
`
`Ex. 1008 at Fig. 1, 2:10-19.) One of ordinary skill in the art would have also
`
`understood that the 115 V 60 Hz AC signal disclosed by Ingraham I is a periodic
`
`signal that oscillates at a predefined frequency4 of 60 Hz. (Ex. 1002 at ¶ 43.)
`
`While Ingraham I does not explicitly disclose an oscillator circuit, one of
`
`ordinary skill in the art would have understood that an oscillator circuit is
`
`necessary to generate the 60 Hz AC signal. (Ex. 1002 at ¶ 44.) (See also Ex. 1001
`
`at 3:44-56, stating that Ingraham I discloses an “oscillator” voltage.”) In any
`
`event, Caldwell discloses an oscillator 30 that provides an oscillating signal (a
`
`periodic square wave) having a predefined frequency (e.g., 100 kHz, 200 kHz) to a
`
`matrix of touch pads. (See supra Section VII.F, discussing Ex. 1009 at Fig. 12,
`
`4:39-46, 6:40-52.) As discussed below, it would have been obvious to one of
`
`ordinary skill in the art at the time of the alleged invention of the ’183 patent to
`
`modify the system of Ingraham I, based on Caldwell, to provide an oscillator that
`
`generates a periodic signal (e.g., 115V 60 Hz AC signal) for the circuitry of the
`
`touch sensing system in Ingraham I. (Ex. 1002 at ¶ 45.)
`
`
`
` 4
`
` Patent Owner’s infringement contentions confirm that “all oscillators have a
`
`predefined frequency.” (Ex. 1013 at 12.)
`
`16
`
`
`
`Petition for Inter Partes Review
`Patent No. 5,796,183
`One of ordinary skill in the art would have been encouraged to look to the
`
`teachings of Caldwell to refine the features of Ingraham I because both references
`
`disclose sensors that detect a user’s touching of a touch terminal based on a change
`
`in capacitance resulting from the user’s touch. (Ex. 1002 at ¶ 46; Ex. 1007 at
`
`1:65-2:2, 3:1-37; Ex. 1009 at 7:39-42, 7:56-65.) In particular, one of ordinary skill
`
`in the art would have been motivated to modify Ingraham I based on Caldwell in
`
`order to allow the system of Ingraham I to function in a portable system (e.g., a
`
`system such as an automobile in which a connection to the building’s power supply
`
`is unavailable). (Ex. 1002 at ¶ 47.) One of ordinary skill in the art would have
`
`recognized that in such a portable system, due to the absence of an AC power
`
`source (e.g., a 115 VAC 60 Hz source), an oscillator would be required to generate
`
`the AC signal for the touch sensing circuits and input portions 13 of the touch pad
`
`assembly 10 in Ingraham I. (Id.) Such a skilled person would have had the
`
`knowledge and capability to implement a dedicated oscillator circuit that could
`
`generate the required AC signal at the desired voltage and frequency (e.g., 115
`
`VAC signal for the system of figure 3 in Ingraham I) from a DC power supply
`
`(e.g., a car battery). (Id.) Ingraham III5 confirms
