`
`INTRODUCTION
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`The Patent Trial and Appeal Board (“Board”) should decline to institute trial
`
`because the petition fails to establish a reasonable likelihood that Apple Inc.
`
`(“Petitioner”) would carry its burden to show that any claim of U.S. Patent No.
`
`8,749,507 (Ex. 1001, the “‘507 patent”) is not patentable.
`
`The Petition asserts 2 separate grounds: Ground 1, alleging that claims 1-5,
`
`9-12, and 14-17 are obvious under 35 U.S.C. § 103(a) in light of Toda (Ex. 1003)
`
`in view of Shahoian (Ex. 1004); and Ground 2, alleging that claims 1, 9, and 14 are
`
`obvious under 35 U.S.C. § 103(a) in light of Morimura (Ex. 1005) in view of
`
`Shahoian. Neither ground has merit.
`
`The ‘507 patent teaches improved ways to determine whether a user
`
`intended to “press” an input device such as a touchpad. Because of differences
`
`between users, such as the size of fingers, determining intent presents challenges,
`
`resulting in errors and inefficiency in pressure-sensitive systems. The claims of the
`
`‘507 patent address this problem by, among other things, requiring each of three
`
`criteria to be met in order to determine whether a user’s contact with an input
`
`device is intended to be a press gesture, then in response to determining the gesture
`
`outputting a haptic effect. In the claims of the ‘507 patent, each of the following
`
`must be determined before determining a press and outputting the confirmatory
`
`haptic effect: (1) that pressure on the input device is greater than a pressure
`
`10086453
`
`
`- 1 -
`
`
`
`
`
`
`threshold, (2) that the change in pressure is greater than a change in pressure
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`threshold, and (3) that an interval has elapsed. The references on which the
`
`Petition relies do not disclose or teach this combination of criteria to determine a
`
`press and a confirmatory haptic effect.
`
`First, the Toda reference does not teach that a press may be determined only
`
`if all the conditions described in the claims of the ‘507 patent are satisfied. For
`
`example, Toda does not teach determining a press based on a determination that a
`
`time interval has elapsed. To the extent that Toda considers the element of time, it
`
`directly teaches away from using elapsing of a time interval as a required condition
`
`by teaching use of algorithms in which, no matter how small the time interval, it is
`
`always possible to determine a press. Petitioner does not allege that Shahoian
`
`discloses this missing element (and it does not). Petitioner therefore has not made
`
`a prima facie case of obviousness for Ground 1.
`
`Second, the Morimura reference is directed to an entirely different
`
`functionality: a system for changing the display and function of a cursor so a user
`
`can interact with (draw) with a pen on a tablet. Morimura does not involve
`
`determining a press at all. Further, Morimura does not disclose making any such
`
`determination based on the lapsing of a time interval. Petitioner therefore has not
`
`made a prima facie case of obviousness for Ground 2.
`
`Additionally, neither Morimura nor Toda concern haptics at all. Petitioner
`
`10086453
`
`
`- 2 -
`
`
`
`
`
`
`therefore concedes that neither Morimura nor Toda discloses the required element
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`of outputting any haptic effect. The Petition argues that a person of skill in the art
`
`would be motivated to add haptics to touchpads based on Shahoian, but fails to
`
`provide any teaching or motivation to add confirmatory haptics to the type of
`
`systems described in Morimura or Toda. In these systems, adding additional
`
`complexity, processing power, and weight for haptic output would have been both
`
`unnecessary (because in both systems the user is looking directly at the screen and
`
`receives visual confirmation) and disruptive (because, for example in the
`
`Morimura system which is designed for drawing on the screen with a pen,
`
`vibrating the pen could prevent the user from drawing in a straight line and cause
`
`errors). This is an additional reason that Petitioner has not made a prima facie case
`
`of obviousness for Ground 1 or Ground 2.
`
`Third, none of the references cited by Petitioner disclose the use of contact
`
`data comprising both an actual pressure and a pseudo pressure, as required by
`
`dependent claims 2, 10, and 15. Indeed, Petitioner does not contend that the
`
`combination of Morimura and Shahoian (Ground 2) renders these claims obvious.
`
`Further, Petitioner concedes that Toda does not disclose this element. Petitioner
`
`relies instead on Shahoian’s discussion of “capacitive touchpads” and “pressure
`
`sensors,” but neither component measures contact area – a critical component of
`
`pseudo pressure as described in the ‘507 patent, as explained further below in
`
`10086453
`
`
`- 3 -
`
`
`
`
`
`
`Section IV (Claim Construction). Moreover, as Petitioner concedes, Shahoian
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`never discloses or suggests using both actual pressure and pseudo pressure in one
`
`device, as these claims require. To the contrary, the Petition concedes that
`
`Shahoian discusses pressure sensors “in contrast to” capacitive sensors, see Pet. at
`
`36-37, and teaches that one type or sensor or the other will be “better suited for the
`
`present invention” depending on the embodiment, see Ex. 1004, ¶ 41. Petitioner’s
`
`argument that it would be obvious to modify the references to use a combination of
`
`actual pressure and pseudo pressure is pure hindsight analysis, untethered from
`
`(and the opposite of) the teachings of the cited prior art.
`
`The Board should decline institution of an inter partes review, at least based
`
`on the aforementioned deficiencies in the prior art cited in Grounds 1 and 2.
`
`II. THE ‘507 PATENT
`The ‘507 patent, in general, relates to interpreting a user’s intent and
`
`providing haptic feedback based on contact data received from a touch-sensitive
`
`input device, such as a touchscreen. Ex. 1001, Abstract. In conventional touchpad
`
`devices, the system may attempt to determine the user’s intent based on the amount
`
`of pressure the user applies to the touchpad; for example, if the user presses hard
`
`enough, the system may determine that the user intends to perform some mouse-
`
`like function, such as a click. Id., 1:46-53. However, as the ‘507 patent notes:
`
`“Because of the variety of users that may interact with a touchpad and the variety
`
`10086453
`
`
`- 4 -
`
`
`
`
`
`
`of functions that may be performed, determining the user’s intent based on a
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`gesture on a touchpad is difficult.” Id., 1:55-58. For example, because of physical
`
`differences between users and variability in the way that users interact with input
`
`devices, the amount of pressure alone may not be sufficient to accurately determine
`
`the user’s intent. Id., 1:58-2:3. In other words, in prior art systems, the user’s
`
`actions may be inadvertently processed as a particular gesture, even though the
`
`user did not actually intend to perform the gesture. Id.
`
`The invention of the ‘507 patent improved on the prior art by requiring a
`
`combination of three conditions – pressure exceeding a pressure threshold, change
`
`in pressure exceeding a change in pressure threshold, and elapsing of a time
`
`interval – to all be satisfied to determine whether the user has intended to press the
`
`screen. Id., Fig. 3. A confirmatory haptic effect is generated in response if it is
`
`determined that the user intended a press input gesture. Id., 4:47-55. As discussed
`
`in the Background of the ‘507 patent, it is desirable to accurately determine the
`
`user’s intent in contacting a touch-sensitive input device because, for example, the
`
`user may inadvertently contact the touch-sensitive input device. Id., 2:1-3. The
`
`‘507 patent claims a method and apparatus that more accurately determines the
`
`user’s intent, including avoiding unintentionally recognizing inadvertent contact as
`
`a press. Exhibit 2001, Declaration of Daniel Wigdor, Ph.D. (“Wigdor Decl.”) ¶ 18.
`
`For example, as disclosed in the ‘507 patent, a touchpad can provide X and
`
`10086453
`
`
`- 5 -
`
`
`
`
`
`
`Y position information and also a Z parameter that relates to the pressure applied
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`by the user. Id., 2:39-45. The ‘507 patent teaches that the Z parameter can be
`
`based on one or both of an actual pressure and pseudo pressure. Id., 2:53-3:31.
`
`The ‘507 patent discloses a pair of exemplary processes for determining
`
`whether the user’s contact is a press. A flow chart for one of the processes is
`
`shown in Figure 3 and is reproduced below.
`
`
`
`This process initially determines whether the Z parameter (e.g., pseudo
`
`
`
`10086453
`
`
`- 6 -
`
`
`
`
`
`
`pressure) is above an upper threshold in step 302. Id., 8:5-8. A first tick count is
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`started in step 316 if it is determined that there was not a previous touching in step
`
`314. Id., 8:21-30. The speed at which the finger is moving over the surface is
`
`compared with a speed threshold in step 320. Id., 7:65-8:4. If the speed is lower
`
`than a speed threshold, then the process determines whether a change in pressure is
`
`greater than a change in pressure threshold and whether a first interval has elapsed.
`
`Id., 8:41-49. If the answers to these determinations are YES then the process
`
`concludes that the user intended a press.
`
`The’507 patent discloses that the combination of all three of these
`
`conditions—a pressure exceeding a pressure threshold, a change in pressure
`
`exceeding a change in pressure threshold, and a lapsing of a particular time
`
`interval—is important in accurately determining whether the user intended a press.
`
`Wigdor Decl. ¶ 22. For example, the inventors of the ‘507 patent recognized that
`
`users tend to push harder when they first touch a touchpad. Ex. 1001, 6:58-62. In
`
`other words, even if the user only intends to touch the touchpad, and does not
`
`intend to perform a press gesture, the user may nonetheless naturally apply a large
`
`pressure when first making contact with the device. See id.; Wigdor Decl. ¶ 22.
`
`Thus, the lapsing interval requirement is important – in combination with the other
`
`requirements – in preventing an inadvertent touch from being considered,
`
`incorrectly, as a press. Id.
`
`10086453
`
`
`- 7 -
`
`
`
`
`
`
`
`Claim 1 of the ‘507 is recited below:
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`A method comprising:
`1.
`receiving contact data from an input device;
`determining an interaction with a displayed object on a screen
`based on the contact data;
`responsive to determining the interaction, determining a gesture
`based on the contact data comprising:
`determining a pressure and a change in pressure based on the
`contact data, and
`determining a press if:
`the pressure is greater than a pressure threshold;
`the change in pressure is greater than a change in
`pressure threshold, and
`a first interval has lapsed; and
`responsive to determining the gesture, outputting a haptic
`effect.
`Independent claims 9 and 14 are similar in scope. The claims require the
`
`determination of a press gesture only if (1) a pressure is greater than a threshold,
`
`(2) a change in pressure is greater than a threshold, and (3) a first interval has
`
`lapsed, and a confirmatory haptic feedback upon satisfaction of all three
`
`conditions. Per the language of the claims, a press gesture is determined and
`
`haptic feedback provided in response only if all three conditions are satisfied by
`
`the user’s contact.

`
`
`III. PERSON HAVING ORDINARY SKILL IN THE ART (POSITA)
`A person of ordinary skill in the art for the field of the ‘507 patent would
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`have at least: a Bachelor of Science degree in an engineering discipline such as
`
`Mechanical Engineering or Computer Science, or at least two years of experience
`
`working with human machine interface systems, graphical user interfaces, haptic
`
`feedback systems, or mobile devices or equivalent embedded systems. Wigdor
`
`Decl. ¶ 25. The conclusions regarding claim construction and validity contained
`
`herein would be the same regardless of whether Immersion’s or Petitioner’s
`
`proposed level of skill is adopted by the Board. Wigdor Decl. ¶ 26.
`
`IV. CLAIM CONSTRUCTION
`During inter partes review, a patent claim shall be given “its broadest
`
`reasonable construction in light of the specification of the patent in which it
`
`appears.” Cuozzo Speed Techs., LLC v. Lee, 136 S. Ct. 2131, 2133, 195 L. Ed. 2d
`
`423 (2016) (quoting 37 C.F.R. § 42.100(b).) The standard for claim construction
`
`at the Patent Office is different from that used during a U.S. District Court
`
`litigation. See PPC Broadband,Inc., v. Corning Optical Comms. RF, LLC, 815
`
`F.3d 747, 756 (Fed. Cir. 2016); 37 C.F.R. § 42.100(b). Immersion expressly
`
`reserves the right to argue a different claim construction in litigation for any term
`
`of the ‘507 patent, as appropriate in that proceeding.
`
`10086453
`
`
`- 9 -
`
`
`
`
`
`The claim term “pseudo pressure” appears in dependent claims 2, 10, and 15
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`
`
`of the ‘507 patent. Claim 2 of the ‘507 patent recites: “The method of claim 1,
`
`wherein the contact data comprises an actual pressure and a pseudo pressure.”
`
`Claims 10 and 15 have similar language. Patent Owner’s proposed construction
`
`for the term “pseudo pressure” is “a measure of the area of the screen contacted by
`
`an object.” This construction is consistent with the surrounding claim language
`
`and the specification, which make clear that “pseudo pressure” can occur in input
`
`devices that utilize a variety of different touchpad technologies.
`
`In the context of the claimed invention, the pseudo pressure is a measure of
`
`the area of the screen contacted by an object, which the ‘507 patent explains is part
`
`of the “contact data” upon which a determination of pressure and change in
`
`pressure is based. See, e.g., ‘507 patent at claim 2 (reciting “The method of claim
`
`1, wherein the contact data comprises an actual pressure and a pseudo pressure”)
`
`(emphasis added); claim 1 (reciting “A method comprising: receiving contact data
`
`from an input device” and then using it to “determin[e] an interaction with a
`
`displayed object on a screen based on the contact data” and “determin[e] a pressure
`
`and a change in pressure based on the contact data”).
`
`The specification explains how the pseudo-pressure—the area of the
`
`touchpad contacted by the user’s finger—may be useful in analyzing the user’s
`
`motions. Ex. 1001, 3:15-19 (“In other words, the pseudo pressure or Z parameter
`
`10086453
`
`
`- 10 -
`
`
`
`
`
`
`provided by the touchpad102 is not a measure of the actual vertical displacement
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`by a conductor at a single point on the touchpad 102, but rather an estimation of
`
`the vertical displacement based on the size of the capacitance change.”); id. at
`
`3:24-28 (“[I]f a user presses heavily against the touchpad 102 with a fleshy part of
`
`the finger, the amount of touchpad 102 area covered by the finger is greater than
`
`when the same part of the finger is touching lightly.”) (emphasis added). That is,
`
`because the user’s finger is deformable, the finger will tend to flatten out and cover
`
`a larger area of the touchpad when the user presses down heavily.
`
`Petitioner argues that “pseudo pressure” should be construed to include “any
`
`measure of pressure based on capacitance.” Pet. at 11. Petitioner’s proposed
`
`construction is incorrect for at least the following reasons.
`
`First, Petitioner’s proposed construction would erase the distinction between
`
`the “pseudo pressure” and “actual pressure” measures that claims 2, 10, and 15
`
`require both be included in the contact data. The ‘507 patent clearly distinguishes
`
`“pseudo pressure” from “actual pressure,” including by explaining that pseudo
`
`pressure is a measure of the screen contacted by the user and “may not accurately
`
`represent the amount of pressure actually exerted on the touchpad.” Ex. 1001,
`
`3:19-21. Actual pressure, on the other hand, is a measure of the amount of
`
`pressure exerted on the touchpad, such as a vertical displacement caused by the
`
`application of pressure, see id., 3:15-21, which may be measured by a pressure
`
`10086453
`
`
`- 11 -
`
`
`
`
`
`
`sensor, id., 2:60-63. But a person of skill in the art would understand that both
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`“pseudo pressure” and “actual pressure” measurements can be determined using
`
`capacitance. For example, pressure sensors known in the art at the time used
`
`capacitive plates to measure deformation caused by the application of pressure.
`
`See, e.g., Ex. 2003, U.S. Patent No. 4,555,952, 1:10-20 (“Pressure sensors known
`
`in the prior art generally teach a pressure or force responsive diaphragm forming
`
`one plate or electrode of a capacitor. This electrode or capacitor plate is subject to
`
`deformation, the extent of which is compared to a second electrode means or
`
`capacitive plate that is not displaced.”); Wigdor Decl. ¶ 23. Under Petitioner’s
`
`proposed construction, this type of well-known actual pressure sensor would be
`
`excluded from the definition of actual pressure because it is “based on
`
`capacitance.” See Pet. at 11. This contradicts not only the understanding in the art
`
`but also the ‘507 patent’s description of how actual pressure – not pseudo pressure
`
`– may be measured using such a pressure sensor. See Ex. 1001, 2:60-63.
`
`Second, the ‘507 patent makes clear that “pseudo pressure” is not defined by
`
`the type of sensing mechanism used (e.g., capacitance). Capacitance-based tools
`
`are only one example of a mechanism for determining the area where a user’s
`
`finger is contacting the screen; the specification clearly states that any touch-
`
`sensitive device may be used. Ex. 1001, 2:55-61 (“The touchpad 102 shown in
`
`FIG. 1 utilizes capacitance, however, an embodiment of the present invention
`
`10086453
`
`
`- 12 -
`
`
`
`
`
`
`may be implemented in conjunction with any touch-sensitive input device,
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`including resistive and membrane-switch touchpads.”) (emphasis added). As
`
`discussed above, the defining characteristic of pseudo pressure is what is being
`

`
`V. CLAIMS 1-5, 9-12 AND 14-17 ARE NOT OBVIOUS OVER TODA IN
`VIEW OF SHAHOIAN
`A. The Toda Reference
`U.S. Patent No. 5,673,066 to Toda et al. (“Toda”) discloses a coordinate
`
`input device for moving a cursor on the screen of a computer that determines a
`
`switching operation based on touch pressure and operational movement of the
`
`input (e.g., user’s finger). Ex. 1003, 2:20-26, Abstract. Toda discloses several
`
`processes (scenarios) for determining whether the user intended a switch input, as
`
`opposed to dragging the cursor on the screen. See id., Figures 11, 14, 15(a)-(b),
`
`17, 18(a)-(b), and 19(a)-(b). The algorithms are used to determine various points
`
`on graphs created from empirical data generated when user intended a switching
`
`input. See Figures 9(a)-(b), 10(a)-(b), 12(a)-(b), 13(a)-(b), 15(a)-(b) and 16(a)-(b).
`
`The ‘507 patent expressly requires that a press be determined when all three
`
`conditions are met: (1) pressure on the input device is greater than a pressure
`
`threshold, (2) a change in pressure has occurred that is greater than a change in
`
`pressure threshold, and (3) an interval has elapsed. Toda is an example of a
`
`10086453
`
`
`- 13 -
`
`
`
`
`
`
`different approach to attempting to determine the user’s intent. Unlike the ‘507
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`patent, Toda does not require that each of these three conditions must be met in
`
`order to determine a press. Indeed, none of Toda’s algorithms require the elapsing
`
`of an interval for a press to be determined. Instead, Toda relies upon “peak”
`
`pressure measurements, and its algorithms use time data only to select the next step
`
`of the flow chart to proceed to. In none of Toda’s algorithms does a finding that
`
`the time interval has not elapsed produce a NO. See id., Figures 11, 14, 17-19. No
`
`matter how small the time interval, it is always possible in Toda to determine a
`
`press. Id.
`
`Further, in the Toda system, the outcome is not conditioned on exceeding a
`
`change in pressure threshold. While change in pressure is a variable in some
`
`branches of the Toda algorithms, there are also multiple other scenarios where a
`
`press is determined without ever determining that the change in pressure has
`
`exceeded a change in pressure threshold. See Section V.D, below. In each respect,
`
`this is the complete opposite of the ‘507 patent, an innovation of which is that a
`
`highly efficient and accurate way to determine a press only when all three
`
`conditions are satisfied.
`
`For example, Fig. 9(a) of Toda, reproduced below, shows a touch load
`
`versus time graph corresponding to a switch input. Id., 4:4-7. The data includes
`
`peak points P1 and P2.

`Patent No. 8,749,507
`
`
`
`The Toda system looks at the user’s input to detect these “peak points” (e.g.,
`
`P1 and P2), in order to match the user’s input to the experimental touch profile of
`
`Fig. 9. For example, if the force detected matches the Fig. 9 touch profile, a
`
`switching input will be turned on. See id., 8:59-9:3. This process is shown in the
`
`flowchart of Fig. 11 reproduced below.

`
`
`
`In the initial step 101, it is determined whether the touch force exceeds 15g.
`
`Id., 9:10-13. If YES the process determines where the peak pressure P1 occurs on
`
`the graph. Id., 9:16-17. If P1 occurs in the first 30 milliseconds, then the process
`
`flows to decision steps 108 and 109. Id., 9:38-52. If there is a YES for both
`
`decision steps 108 and 109 then the switching input is turned on. Id., 9:53-57. If
`
`P1 occurs after the first 30 milliseconds, the process flows to Process 3. See id.,
`
`10086453

`
`
`
`
`
`Fig. 11. In Process 3, the user’s input is compared to another experimental touch
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`profile, illustrated in Fig. 15(a), reproduced below.
`
`The data includes a rising point P3 and a peak point P4. Process 3 is
`
`depicted in the flowchart of Fig. 17 reproduced below.

`Patent No. 8,749,507
`
`
`
`In this process, the system detects rising point P3 and peak point P4, again in
`
`order to match the user’s input to the experimental touch profile in Fig. 15(a). For
`
`example, the process determines whether the touch pressure at P4 is over 150g
`
`(step 127) and whether the lateral movement between P3 and P4 is not over 10
`
`(step 128). Id., Fig. 17. If so, switch inputting is turned on (step 129). Id.
`
`Notably, a determination that the user intended to turn on the switch never
`
`requires a finding that an interval has elapsed. As discussed above, the only import
`
`10086453
`
`
`- 18 -
`
`
`
`
`
`
`of the passage of time is to determine the next step in the flow chart. For example,
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`at step 103 of Figure 11, the system asks whether P1 was detected in less than 30
`
`milliseconds. However, the answer only determines the next step in the flow chart.
`
`Both paths (P1 detected in less than 30 milliseconds, and detected in more than 30
`
`milliseconds) contain numerous paths to determining that a switch was intended
`
`(and also numerous paths to determining that a switch was not intended).
`
`Similarly, Toda’s system also can determine a press without any
`
`determination of a change in pressure greater than a change in pressure threshold.
`
`For example, if the user’s initial force exceeds 75g and the user’s finger does not
`
`move, Toda’s algorithm will reach the “SWITCH INPUTTING ON” step based
`
`solely on the user’s force, without considering any change in pressure or time
`
`interval. See id., Fig. 11; Wigdor Decl. ¶ 34. This is the very same flawed prior
`
`art approach criticized by the inventors of the ‘507 patent. See, e.g., Ex. 1001,
`
`1:53-2:3 (describing problems with determining intent based only on changes in
`
`position and pressure exerted on touchpad).

`The Shahoian Reference
`
`B.
`U.S. Patent Application Publication No. 2002/0033795 to Shahoian et al.
`
`(“Shahoian”) discloses a computer system with a touch input device and an
`
`actuator that can provide haptic feedback in response to user inputs on the touch
`
`input device. Ex. 1004, [0008]. The touch input device provides coordinate data
`
`10086453
`
`
`- 19 -
`
`
`
`
`
`
`to a processor based on the sensed location of an object near the touchpad. Id.,
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`[0041]. The system may include a local microprocessor that receives input signals
`
`from the sensors and provides output signals to actuators in accordance with
`
`instruction from a host processor. Id., [0066]. The actuator provides haptic
`
`feedback to the user. Id. Haptic feedback is provided in response to detection of
`
`contact by the user on the touch input device. Id., [0077].
`
`C. Neither Toda Nor Shahoian Discloses The “determining a press if:
`a first interval has lapsed” Claim Limitation
`
`All of the challenged claims require “determining a press if:….the pressure
`
`is greater than a pressure threshold, the change in pressure is greater than a change
`
`in pressure threshold, and a first interval has elapsed.” By way of example, Fig.
`
`3 of the ‘507 patent shows the starting of a first tick count in step 316 that begins
`
`an interval. Ex. 1001, 8:26-28. In step 324, it is determined whether an interval
`
`has lapsed. Id., 8:44-49. The process shows the starting of a timer and then an
`
`active determination on whether a time interval from the starting of the timer has
`
`elapsed. A press can only be determined if the interval has lapsed. A NO decision
`
`in step 324 causes the process to return to step 302. In such a scenario, a press is
`
`not registered. Id., Fig. 3.
`
`The Petitioner contends that Toda discloses the first interval has elapsed
`
`limitation, citing to different decision blocks in the Toda processes. Pet. at 26-27.
`
`10086453
`
`
`- 20 -
`
`
`
`
`
`
`None one of these decision blocks involve determining whether a first interval has
`
`Case IPR2016-01777
`Patent No. 8,749,507
`
`elapsed.
`
`The Petitioner initially cites to a portion of Toda which discloses the
`
`determination of whether the touch pressure F has, or has not, sequentially
`
`exceeded 10g three times by comparing data on the currently sampled F with two
`
`previous samples. Pet. at 26. This step is performed to determine the existence of
`
`peak P3. Ex. 1003, 11:42-45; Wigdor Decl. ¶ 37. This is not determining whether
`
`a time interval has lapsed. Petitioner argues that it takes time to obtain and analyze
`
`the data and therefore there is a lapse of time. Pet. at 28. Even if this is true, the
`
`relevant point is that Toda is not determining whether a time interval has lapsed.
`
`The claims require “determining a press ‘if’….a first interval has lapsed.” A
`
`POSITA would understand that an “if” statement means that the condition may or
`
`may not be satisfied. Wigdor Decl. ¶ 36. This is shown in Fig. 3 of the ‘507 patent
`
`wherein there is a determination on whether the interval lapsed. If this condition is
`
`satisfied – along with the other conditions – then the process determines a press.
`
`Ex. 1001, 8:44-49. If the answer in decision block 324 is NO, t
