`
`IDENTIFICATION OF CHALLENGE PURSUANT TO 37 C.F.R.
`§ 42.104(B)
`
`Petitioners request that claims 1, 6-9, and 14 of the ’802 Patent be found
`
`unpatentable.
`
`A.
`
`37 C.F.R. § 42.104(b)(1): Claims for Which Inter Partes Review Is
`Requested
`
`Petitioners request inter partes review of claims 1, 6-9, and 14 of the ’802
`
`Patent.
`
`B.
`
`37 C.F.R. § 42.104(b)(2): The Specific Art and Statutory
`Ground(s) on Which the Challenge Is Based
`Inter partes review of the Challenged Claims is requested in view of the
`
`following prior art: (1) U.S. Patent No. 4,870,333 to Itoh et al. (“Itoh”)
`
`(Ex. 1007); (2) U.S. Patent No. 4,468,596 to Kinzl et al. (“Kinzl”) (Ex. 1008); and

`
`37 C.F.R. § 42.104(b)(3): How the Challenged Claims Are to Be
`Construed
`
`An unexpired claim subject to inter partes review “shall be given its
`
`broadest reasonable construction in light of the specification of the patent in which
`
`it appears.” 37 C.F.R. § 42.100(b). However, the ’802 Patent will expire in
`
`November, 2014, prior to the date on which any IPR initiated based on this petition
`
`is expected to conclude. Therefore, consistent with MPEP § 2217 and Innolux
`
`Corp. v. Semiconductor Energy Lab. Co. Ltd., IPR2013-00065, Paper 11, 10
`
`(Apr. 30, 2013), Petitioners provide information about how the claims are to be
`
`construed based upon the standard set forth in Phillips v. AWH Corp., 415 F.3d
`
`
`
`4
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,579,802
`
`1303, 1316 (Fed. Cir. 2005).1 Evidence supporting these constructions includes
`
`the infringement positions taken by the patent owner, UUSI, in its Federal Court
`
`litigation against BNA. 35 U.S.C. § 301(a)(2); 37 C.F.R. § 1.501. Attached as
`
`Exhibit 1003 is Brose’s Submission Pursuant to 35 U.S.C. § 301 and 37 C.F.R.
`
`§ 1.501 in support of this Petition. Petitioners submit, for purposes of this IPR
`
`only, the following proposed constructions:
`
`1.
`
`“a controller . . . for determining to de-activate the motor”
`(claim 1); “a signal . . . for stopping the motor” (claim 7);
`and “de-activating the motor” (claim 14)
`
`Petitioners propose that these three phrases should be given their plain
`
`meanings and construed to require de-activating/stopping the motor. Such a
`
`construction would exclude a system that immediately reverses the motor without
`
`first deactivating/stopping the motor. The 1992 application to which the ‘802
`
`Patent claims priority discloses “de-energizing” the motor, and distinguishes
`
`reversing the motor, which it says might be impossible at higher speeds. (Ex. 1031
`
`at 6:64-7:2). Such a construction is consistent with how one of skill in the art
`
`would understand this term. (Ex. 1001, ¶ 57.) This construction is also supported
`
`by the ’802 Patent’s specification, which distinguishes (and even disparages) an
`
`approach of immediately reversing (without first deactivating/stopping) the motor
`
`1 If instead the “broadest reasonable construction” standard were to be applied,
`
`the Challenged Claims are also invalid under such broader constructions.
`
`
`
`5
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,579,802
`
`in response to an obstacle. (Ex. 1005 at 3:44-57 (describing “motor plugging,”
`
`“which is the application of reserve drive polarity while a motor is still rotating” as
`
`“unnecessary” and “undesirable” due to “undesired motor heating,” because it is
`
`“detrimental to the life and reliability” of the electrical switching components, and
`
`because it “can also cause undesirable transients, trip breakers, and blow fuses in a
`
`power supply system”).)
`
`Moreover, a review of the patentee’s other, earlier patents shows that the
`
`patentee knew how to recite the broader concept of altering the motor operation.
`
`(Ex. 1010, ’165 Patent, at Claims.) Therefore, by choosing to use the word “de-
`
`activate” or “stopping” in the Challenged Claims, the patentee meant to exclude a
`
`system that immediately reverses (without first de-activating/stopping) the motor
`
`upon detection of an obstacle and must be held to its choice.
`
`2.
`
`“a movement sensor for monitoring movement of the object
`(claim 7) and “a sensor for sensing movement of a window
`or panel” (claim 14)
`
`Petitioners propose that these phrases should be construed to include both
`
`direct and indirect sensing of the window/panel movement, and not limited to just
`
`direct sensing. The 1992 application to which the ’802 Patent claims priority
`
`discloses Hall sensors, as well as explaining that other types of sensors could be
`
`used. (Ex. 1020 at 1:61-63 and 3:49-52.) This construction is also supported by the
`
`’802 Patent’s specification, which discloses both types of sensors: (1) sensors that
`
`
`
`6
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,579,802
`
`directly sense movement of the window (Ex. 1005 at 10:16-20), and (2) sensors
`
`that indirectly sense movement of the window by sensing something else, such as
`
`motor rotation. (Id. at 10:4-15.) Such a construction is consistent with how one of
`
`skill in the art would understand this term. (Ex. 1001, ¶ 58.)
`
`The prosecution history further supports such a construction. The Examiner
`
`found that a Hall effect sensor that indirectly monitored movement of the window
`
`(by directly monitoring the rotation of the motor, which is physically coupled to
`
`the window) meets the “sensor” limitation of independent claims 7 and 14
`
`(pending claims 12 and 19). (Ex. 1024 (07/23/2008 Office Action).) The
`
`Examiner also accepted applicant’s assertion, in its August 19, 2008 Response, that
`
`such a Hall effect sensor (“Movement sensor, position encoder” citing column 4,
`
`line 16 of the 1992 specification, which is Ex. 1031) satisfied the “sensor”
`
`limitation of claim 7 (pending claim 12), and “op amp 110” (citing column 5, line
`
`19, which discloses a motor current sensor) satisfied the “sensor” limitation of
`
`claim 14 (pending claim 19). (Ex. 1025 at 12, 17-18.)
`
`The patentee also consistently applies a construction where the accused
`
`“sensor” is a Hall effect sensor—that monitors motor rotation—in the UUSI v.
`
`BNA litigation. (Ex. 1033 at 14-16, 26-28, and 34-35.)

`
`V. THERE IS A REASONABLE LIKELIHOOD THAT AT LEAST ONE
`OF THE CHALLENGED CLAIMS IS UNPATENTABLE.
`A. Description of the Alleged Invention of the ’802 Patent
`The specification of the ’802 Patent describes a number of systems, methods
`
`and features, many of which were added to the specification over the course of 11
`
`years through three continuations-in-part. Significant portions of specification are
`
`unrelated to the subject matter claimed in the Challenged Claims, but the
`
`
`
`8
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,579,802
`
`specification is generally directed to reducing the risk of personal injury that could
`
`result if a limb (e.g., an arm) is caught by a power-operated device, such as, for
`
`example, during the closing of a power window or sunroof in a vehicle. (Ex. 1001
`
`at 1:30-57 (“Background”) and 1:59-2:22 (“Summary of the Invention”).)
`
`
`
`Independent claim 1 is directed to an apparatus for controlling motion of a
`
`motor driven element in a vehicle (e.g., a power window motor, or a power sunroof
`
`motor) in response to an undesirable resistance (e.g., from an obstacle) and recites
`
`the combination of (a) a sensor for measuring a parameter of the motor, (b) a
`
`memory for storing measurement values from the sensor, and (c) a controller for
`
`determining to de-activate the motor based on both (i) the most recent sensor
`
`measurement, and (ii) immediate past measurement values stored in the memory
`
`and obtained during the present run (e.g., obtained earlier in the present closing
`
`cycle of the window). (Ex. 1005, claim 1.)
`
`Dependent claim 6, which depends from claim 1, requires the “immediate
`
`past measurements of said parameter were taken within a forty millisecond interval
`
`prior to the most recent sensor measurement.” (Ex. 1005, claim 6.)
`
`Independent claim 7 recites (a) a movement sensor for monitoring
`
`movement of the object (e.g., a window), (b) a switch for controlling energization
`
`of the motor, and (c) a controller. The controller determines the motor speed,
`
`calculates a threshold based on motor speed detected during the present run,
`
`
`
`9
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,579,802
`
`compares the present speed to the threshold, and outputs a signal to the switch for
`
`stopping the motor if the comparison indicates an obstacle. (Ex. 1005, claim 7.)
`
`Dependent claim 8 depends from claim 7 and adds the requirement of “a
`
`buffer memory for storing successive values of motor movement for use in
`
`determining the obstacle detect threshold.” (Ex. 1005, claim 8.)
`
`Dependent claim 9 depends from claim 7 and is directed to the details of
`
`how the controller uses a clock to count pulses from the sensor in order to
`
`determine the motor speed. (Ex. 1005, claim 9.)
`
`Independent claim 14 recites (a) a sensor for sensing movement of the object
`
`(e.g., a window), (b) a switch for controlling energization of the motor, and (c) a
`
`controller. The controller monitors a signal from the sensor, calculates a real time
`
`threshold based on a sensor signal detected earlier during the present run, compares
`
`the present signal to the threshold, and outputs a signal to the switch for stopping
`
`movement of the window. (Ex. 1005, claim 14.)
`
`Summary of the Prosecution History of the ’802 Patent
`
`B.
`The ’802 Patent issued August 25, 2009 from U.S. Patent Appl. No.
`
`10/765,487 (“the ’487 Application”) filed January 27, 2004. (Ex. 1001.) The
`
`asserted chain of priority is shown in Exhibit 1034. During prosecution, the
`
`Challenged Claims were numbered as follows:
`
`
`
`10
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,579,802
`
`(Issued) Challenged Claim
`

` Dependent claim 9
`Independent claim 14
`
`Claim 1
`Claim 36
`Claim 12
`Claim 13
`Claim 14
`Claim 19
`
`In the first Office Action, the Examiner rejected all pending claims (1-35) as
`
`anticipated by Wang (effectively filed August 30, 1995). (Ex. 1013.) In a May 31,
`
`2006 submission, applicant argued that Wang was not prior art because all pending
`
`claims were supported by applicant’s April 22, 1992 application (serial no.
`
`07/872,190, which issued as U.S. Patent No. 5,334,876, Ex. 1031). (Ex. 1014.)
`
`The Examiner then rejected all pending claims as anticipated or rendered
`
`obvious by Jones et al. (Ex. 1015.) In a December 13, 2006 Response, applicant
`
`amended some claims, canceled a claim, and added new claims 36-37. (Ex. 1016.)
`
`The Challenged Claims were treated as follows:

`
`The Examiner then rejected all claims as obvious over Jones et al. in view of
`
`Wrenbeck et al., which teaches the use of immediate past measurements in a power
`
`window obstacle detection apparatus. (Ex. 1017.) An interview followed, during
`
`which applicant’s priority date was discussed. (Ex. 1018.) In a June 20, 2007
`
`Response, applicant argued that Wrenbeck et al. was not prior art. (Ex. 1019.)
`
`The Examiner agreed that Wrenbeck et al. was not prior art, but then
`
`rejected all claims, relying primarily on Okuyama et al., which pre-dates
`
`applicant’s 1992 filing date. (Ex. 1020.) Applicant then amended certain claims.
`
`(Ex. 1021.) The Challenged Claims were treated as follows:
`
`December 13, 2006 Amendment

`

`
`Petition for Inter Partes Review of U.S. Patent No. 7,579,802
`
`Applicant argued that Okuyama et al. did not anticipate because the relevant values
`
`in that reference were based on “training data stored by the controller during a
`
`previous run” as opposed to being “real time data obtained during a present run of
`
`the window or panel.” (Ex. 1021 at 12-13.)
`
`The Examiner then indicated that most pending claims (including each of the
`
`Challenged Claims) were allowable, but maintained the rejection of three pending
`
`claims (claims 33-35) as anticipated by Okuyama et al. (Ex. 1022.) Applicant
`
`filed a Request for Continued Examination and an Amendment dated June 5, 2008,
`
`in which rejected claims 33-35 were cancelled. (Ex. 1023.) The Examiner then
`
`rejected all pending claims as obvious over Okuyama et al. in view of Bamford
`
`(EP 0 581 509), relying on Bamford for the “immediate past” and “present run”
`
`limitations. (Ex. 1024.) In an August 19, 2008 response, applicant argued that
`
`Bamford was not prior art. (Ex. 1025.)
`
`After another interview (Ex. 1026 is the Examiner’s Summary and Ex. 1027
`
`is the applicant’s Response), most claims were allowed, but others were again
`
`rejected as obvious over Okuyama et al. in view of Bamford. (Ex. 1028.)
`
`Applicant then cancelled the rejected claims (other than claim 36, which applicant
`
`
`
`13
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,579,802
`
`explained was dependent on claim 1 and thus allowable in connection with claim
`
`1), (Ex. 1029), and the application was allowed. (Ex. 1030.)2
`
`C.
`
`Summary of Invalidity Arguments
`1.
`Itoh, which issued in 1989, was disclosed to the Examiner during
`
`Summary of Itoh
`
`prosecution of the ’802 Patent, but was never discussed in any Office Action.
`
`
`
`
`
`
`
`1. Itoh and Claim 1
`
`Itoh includes detailed descriptions of multiple embodiments. Embodiment
`
`3, which is described in detail beginning in Column 7 of the specification, is the
`
`most relevant embodiment. Specifically, Itoh discloses a controller (32) with a
`
`CPU (34) for controlling operation of a motor (20) for a power window in a
`
`vehicle. (Ex. 1007 at 7:53-8:9 and Fig. 7.) The controller/CPU controls the motor
`
`via motor driving circuit 28. (Id.) Motor driving circuit 28 switches the motor,
`
`controlling the direction of rotation of the motor and controlling whether the motor
`
`is on or off. (Id. at 7:57-59, 7:67-8:11, 11:16-19, 11:48-50; Figure 5 (showing
`
`“pulse counter clearing” 113 and “pulse counter resetting” 111); Figure 6 (showing
`
`“Ascending Action” and resulting decrement or increment of the pulse counter);
`
`
`2 Rather than continue to argue that Bamford was not prior art, applicant
`
`cancelled the rejected claims, copied them into another application, and
`
`convinced the Examiner that Bamford was not prior art. (Ex. 1032 at 8.)

`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,579,802
`
`Figure 8 (showing how the timer interruption signal will control the pulse
`
`counting).) The switching of the motor (and the resulting counting of the window
`
`position) will be in response to both the disclosed algorithm, as well as the user
`
`control switches shown in Figure 7 as “Switch Panel” 38.
`
`Itoh’s Embodiment 3 includes a sensor (30) as a pulse-detecting circuit,
`
`from which the CPU 34 detects a position of the window in accordance with a
`
`counter 36, which counts the pulses and compares the count to a map 46 stored in
`
`memory as the window moves along its path. (Id. at 8:10-16.) The sensor is
`
`disclosed as a motor current ripple counter, which is used to detect both window
`
`movement and speed. (Id. at 5:6-10, 8:33-48; 9:16-34 (position), 9:37-62 (speed).)
`
`Itoh’s “CPU 34 detects at all times whether or not an obstacle 48 is caught
`
`between the window frame 24 and the window 26 in accordance with the flow
`
`chart shown in FIG. 5.” (Id. at 49-52.) Itoh detects an obstacle by storing a
`
`number of “n” immediately prior speed values in a FIFO-type memory (Id. at 12-
`
`17, Fig. 9), then calculating the average (Tm) of those speed values (Id. at 10:36-
`
`44), then calculating the rate-of-change of motor speed (Tp/Tm, where Tp is the
`
`instant motor speed value), and comparing that rate-of-change to a predetermined
`
`threshold (α). (Id. at 10:61-66.) If the rate-of-change of the speed (Tp/Tm)
`
`exceeds the α threshold, the CPU issues a signal to the driving circuit 28 to make
`
`the motor reverse direction and the window to descend/open. (Id. at 11:20.)
`
`
`
`15
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,579,802
`
`In the detailed description of Embodiment 3, Itoh discloses that, in response
`
`to an obstacle, its CPU will output a signal to reverse the motor. (Id. at 11:16-20.)
`
`But Itoh elsewhere discloses the idea of deactivating the motor. In the Summary of
`
`the Invention, Itoh teaches deactivating the motor, without reversing the motor, if
`
`the motor speed exceeds a threshold and the window is “near to the closed
`
`position.” (Id. at 3:52-60.) Itoh also teaches that “it is possible to stop the opening
`
`or closing action of the window at a halfway, or possible to convert the action of
`
`the window in the reverse direction.” (Id. at Abstract.)
`
`Accordingly, even though the detailed description of Embodiment 3
`
`discloses reversing the motor, Itoh elsewhere teaches the concept of deactivating
`
`the motor, and one of skill in the art would readily recognize that those teachings
`
`could be applied to Embodiment 3 in order to de-activate the motor, rather than (or
`
`prior to) reversing the motor, in response to obstacle detection. (See Ex. 1001, ¶¶
`
`91, 96-99.)
`
`In addition, it was well within the ordinary skill in the art, and was a routine
`
`design choice, as to how to respond to an obstacle condition, including at least the
`
`options of (i) stopping/deactivating the window motor, (ii) stopping/deactivating
`
`and then reversing the window motor, or (iii) reversing the window motor without
`
`first stopping/deactivating the motor. (See Ex. 1001, ¶¶ 91, 96-99.) To the extent
`
`a reference is necessary to support the obviousness of this routine design choice,
`

`
`Kinzl discloses the idea of deactivating the motor in response to an obstacle.
`
`(Ex. 1008 at 2:24-30 and 3:21-49; Ex. 1001, ¶¶ 91, 96-99.)
`
`
`
`b. Itoh and Dependent Claim 6
`
`Regarding dependent claim 6, which depends from independent claim 1, and
`
`recites details about the time interval (40 ms) within which the “immediate past
`
`measurements of said parameter are taken,” Itoh discloses this limitation. Itoh uses
`
`immediate past measurements measured by a clock running at 0.1 msec. The clock
`
`takes measurements at a rate between 0.4 msec and 0.8 msec, according to Figure
`
`8. Itoh discloses that, in experiments, the measurements were taken at 1.2 msec at
`
`maximum speed. (Ex. 1007 at 9:63-68.) Thus, 33 measurements would be taken
`
`within 40 ms (40/1.2 = 33.3). Itoh leaves it as a design choice how many
`
`immediately past measurements are used, but suggests at least 4 or 5. (Id. at
`
`10:40-45; Fig. 9.) (See also, Ex. 1001, ¶ 107.)
`
`During prosecution of the ’802 Patent, the Examiner found that the 40 ms
`
`timeframe, although not disclosed in the cited Okuyama reference, was obvious to
`
`one having ordinary skill in the art, “since it has been held that where the general
`
`conditions of a claim are disclosed in the prior art, discovering the optimum or
`
`workable ranges involves only routine skill in the art. (Ex. 1024, 07/23/08 Office
`
`Action at 8 (citing In re Aller, 105 USPQ 233). The same is true in the context of
`
`Itoh. (See Ex. 1001, ¶ 109.)
`
`
`
`17
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,579,802
`
`In the preferred embodiment disclosed in the 1992 specification (on which
`
`applicant relied for priority), the design is such that 20 measurements would be
`
`taken within 40 ms and the threshold equation would use a single value from 40 ms
`
`ago. (Ex. 1031 at 6:46-63.) In Itoh, even at very low motor speeds, several
`
`immediately preceding values, taken within 40 ms, are used in the obstacle
`
`detection equation, even if not all the values used are from within that time frame.
`
`(See Ex. 1001, ¶ 108.)
`
`c. Itoh and Claim 7
`
`Regarding claim 7, the threshold (α) in Itoh is described as a constant,
`
`whereas claim 7 recites that the obstacle detect threshold is calculated “based on
`
`motor speed of movement detected during a present run,” and then recites that an
`
`obstacle is detected by “compar[ing] the currently sensed motor speed of
`
`movement with the obstacle detect threshold.” However, upon closer review, the
`
`equation disclosed in Itoh is mathematically identical to approach
