`
`INTRODUCTION
`
`Ford Motor Company ("Petitioner") filed a Petition requesting an
`
`inter partes review of claims 23-30, 32, and 39-41 of U.S. Patent
`
`No. 7,104,347 B2 (Ex. 1401, ''the '347 patent"). Paper 1 ("Pet."). Paice
`
`LLC and The Abell Foundation, Inc. ( collectively, "Patent Owner") filed a
`
`Preliminary Response in both unredacted and redacted forms. Papers 9, 10
`("Prelim. Resp."). 1 Patent Owner also filed a Motion to Seal. Paper 11
`
`("Motion to Seal"). We have jurisdiction under 35 U.S.C. § 314(a), which
`
`provides that an inter partes review may not be instituted "unless ... there is
`
`a reasonable likelihood that the petitioner would prevail with respect to at
`
`least 1 of the claims challenged in the petition." After considering the
`
`Petition, the Preliminary Response, and associated evidence, we conclude
`
`that Petitioner has demonstrated a reasonable likelihood that it would prevail
`
`in showing unpatentability of all the challenged claims, except claim 24.
`
`Thus, we authorize institution of an inter partes review of claims 23, 25-30,
`
`32, and 39-41 of the '347 patent and we do not institute inter partes review
`
`of claim 24 of the '347 patent.

`
`B. The '347 Patent (Ex. 1401)
`
`The '347 patent describes a hybrid vehicle with an internal
`
`combustion engine, two electric motors ( a starter motor and a traction
`
`motor), and a battery bank, all controlled by a microprocessor that directs
`
`the transfer of torque from the engine and traction motor to the drive wheels
`
`of the vehicle. Ex. 1401, 17:5-45, Fig. 4. The microprocessor features a
`
`control strategy that runs the engine only under conditions of high
`
`efficiency, typically when the vehicle's instantaneous torque requirements
`
`(i.e., the amount of torque required to propel the vehicle, or "road load") is
`at least equal to 30% of the engine's maximum torque output ("MTO")
`
`capability. Id. at 20:52-60, 35:5-14; see also id. at 13:47-61 (''the engine is
`
`never operated at less than 30% of MTO, and is thus never operated
`
`inefficiently").
`
`Running the engine only when it is efficient to do so leads to
`
`improved fuel economy and reduced emissions. Id. at 13:47-52. To achieve
`
`such efficiency, the hybrid vehicle includes various operating modes that
`
`depend on the vehicle's torque require~ents, the battery's state of charge,
`
`and other operating parameters. Id. at 19:53-55. For example, the hybrid
`
`vehicle may operate in: (1) an all-electric mode, where only the traction
`
`motor provides the torque to propel the vehicle and operation of the engine

`
`

`Patent 7,104,347 B2
`
`would be inefficient (i.e., stop-and-go city driving); (2) an engine-only
`
`mode, where only the engine provides the torque to propel the vehicle and
`.
`the engine would run at an efficient level (i.e., highway cruising); (3) a dual-
`
`operation mode, where the traction motor provides additional torque to
`
`· propel the vehicle beyond that already provided by the engine and the torque
`
`required to propel the vehicle exceeds the maximum torque output of the
`
`engine (i.e., while accele.rating, passing, and climbing hills); and (4) a
`
`battery recharge mode where the engine operates a generator to recharge the
`
`battery while the traction motor drives the vehicle. Id. at 35:66-36:58,
`
`37:26-38:55.
`
`C. Illustrative Claim
`
`Petitioner challenges claims 23-30, 32, and 39-41 of the '347 patent.
`
`Pet. 4--60. Claim 23 is illustrative of the claims at issue and is reproduced
`
`below:
`
`23. A method of control of a hybrid vehicle, said vehicle
`comprising an internal combustion engine capable of efficiently
`producing torque at loads between a lower level SP and a
`maximum torque output MTO, a battery, and one or more
`electric motors being capable of providing output torque
`responsive to supplied current, and of generating electrical
`current responsive to applied torque, said engine being
`controllably connected to wheels of said vehicle for applying
`propulsive torque thereto and to said at least one motor for
`applying torque thereto, said method comprising the steps of:
`determining the instantaneous torque RL required to
`propel said vehicle responsive to an operator command;
`monitoring the state of charge of said battery;
`employing said at least one electric motor to propel said
`vehicle when the torque RL required to do so is less than said
`lower level SP;

`
`employing said engine to propel said vehicle when the
`torque RL required to do so is between said lower level SP and
`MTO;
`employing both said at least one electric motor and said
`engine to propel said vehicle when the torque RL required to do
`so is more than MTO; and
`employing said engine to propel said vehicle when the
`torque RL required to do so is less than said lower level SP and
`using the torque between RL and SP to drive said at least one
`electric motor to charge said battery when the state of charge of
`said battery indicates the desirability of doing so; and
`wherein the torque produced by said engine when
`operated at said setpoint (SP) is substantially less than the
`maximum torque output (MTO) of said engine.

`
`II. ANALYSIS
`
`A. Patent Owner's Discretionary Dismissal Arguments
`
`Patent Owner first argues that we should exercise our discretion under
`
`35 U.S.C. § 325(d) and reject the Petition because "it relies on substantially
`
`the same arguments that [Petitioner] Ford has already presented to the Board
`
`in three separate proceedings." Prelim. Resp. 14-27. We have considered
`
`Patent Owner's argument, but exercise our discretion and consider the
`
`Petition and institute trial on the grounds summarized below, based in part
`
`on Ibaraki '882, a reference not previously relied on. We also have
`
`considered Patent Owner's arguments regarding multiple attacks on
`
`independent claim 23. Id. at 21-23. Where a dependent claim is challenged,
`
`we see no reason not to consider a challenge of the independent claim from
`
`(Ex. 1433).

`Patent 7,104,347 B2
`
`which it depends over the same prior art, even if the independent claim
`
`already has been challenged elsewhere. Whatever renders obvious the
`
`dependent claim necessarily renders obvious the independent claim.
`
`We also have considered Patent Owner's argument that multiple
`
`challenges should not be allowed because, under 35 U.S.C. § 315(e)(l), once
`
`a final written decision is issued in one proceeding with respect to a claim,
`
`Petitioner would be barred from requesting or maintaining a proceeding on
`
`that claim on any ground that the Petitioner raised or could have raised in the
`
`proceeding which yielded the final written decision. Prelim. Resp. 27-30.
`
`The contention is misplaced, because that provision applies only to the
`
`Petitioner, not the Board. See Progressive Cas. Ins. Co. v. Liberty Mut. Ins.
`
`Co., Nos. 2014-1586, 2014-1466, 2014-1639, 2014-1538, 2014-1638, 2014-
`
`1636, 2014-1656, 2014-1549, 2014-1637, 2015 WL 5004949, at *2 (Fed.
`
`Cir. Aug. 24, 2015). Even if it applies to the Board, it is not burdensome
`
`simply to terminate the second proceeding with respect to certain claims.
`
`B. Claim Construction
`
`The Board interprets claims of an unexpired patent using the broadest
`
`reasonable construction in light of the specification of the patent in which
`
`they appear. See 37 C.F.R. § 42.lOO(b); Office Patent Trial Practice Guide,
`
`77 Fed. Reg. 48756, 48766 {Aug. 14, 2012). Under the broadest reasonable
`
`construction standard, claim terms are given their ordinary and customary
`
`meaning, as would be understood by one of ordinary skill in the art in the
`
`context of the entire disclosure. In re Translogic Tech. Inc., 504 F.3d 1249,
`
`1257 (Fed. Cir. 2007).
`
`1. "Road Load"or "RL"
`
`The term "road load" or "RL" is recited in independent claim 23. The
`
`7
`
`BMW1012
`Page 1330 of 1654
`
`
`
`IPR2015-00794
`Patent 7,104,347 B2
`
`Specification of the '347 patent defines "road load" as "the vehicle's
`
`instantaneous torque demands, i.e., that amount of torque required to propel
`
`the vehicle at a desired speed," and further notes that it "can be positive or
`
`negative, i.e., when decelerating or descending a hill, in which case the
`
`negative road load ... is usually employed to charge the battery." Ex. 1401,
`
`12:38-58. Accordingly, we construe "road load" and "RL" as "the amount
`
`of instantaneous torque required to propel the vehicle, be it positive or
`negative." 11
`
`2. "Set Point" or "SP"
`The term "setpoint" or "SP" is recited in independent claim 23 and
`
`dependent claims 24-30, 32, and 39-41. Petitioner proposes that "setpoint"
`or "SP" be construed, in the context of these claims, as "predetermined
`torque value." Pet. 5--6. In that regard, Petitioner correctly notes that the
`
`claims compare the setpoint either to an engine torque value or a torque
`
`based "road load" value. Id. Independent claim 23 recites a condition
`
`"when the torque RL required to do so is less than said lower level [setpoint]
`
`SP." Ex. 1401, 60:37-39. Independent claim 23 further recites a range
`
`established by the setpoint at one end, and the maximum torque output of the
`
`engine at the other end, by the language "when the torque RL required to do
`
`so is between said lower level SP and [maximum torque output] MTO." Id.
`
`at 60:40-42. Although Patent Owner correctly notes th~J the Specification
`
`outside of the claims refers to two items being measurable against respective
`
`setpoints, i.e., the vehicle's instantaneous torque requirement and the state of
`
`11 This construction is the same as that proposed by Petitioner. Pet. 4-5.
`Patent Owner does not propose a different construction.
`8
`
`BMW1012
`Page 1331 of 1654
`
`
`
`IPR2015-00794
`Patent 7,104,347 B2
`
`charge of the battery bank (Prelim. Resp. 11-12), the setpoint in these claims
`
`relates to torque and not battery charge.
`
`Patent Owner asserts that "setpoint" or "SP" is not simply a numerical
`
`value divorced from the context of the rest of the vehicle's control system,
`
`and that a "setpoint" serves the crucial function of marking the transition
`
`from on~ claimed mode to another, and in particular, the transition from
`
`propelling the vehicle with the motor to propelling the vehicle with the
`
`engine. Prelim. Resp. 8-11. Citing the Specification, Patent Owner further
`
`states that the Specification uses "setpoint" synonymously with ''transition
`
`point." Id at 9-10. Accordingly, Patent Owner urges that the construction
`
`of "setpoint" or "SP" must include an indication that it is a point at which a
`
`transition between different operating modes may occur. Id. at 9-11.
`
`Patent Owner's arguments are misplaced. The Specification outside
`
`of the claims sometimes uses "setpoint" interchangeably with ''transition
`
`point," because the disclosure describes the particular transitions between
`
`operative modes, at the setpoints. If the multiple transitions between modes
`
`are not described, it would be without meaning to refer to a "setpoint" as a
`
`transition point between modes. A transition does not spring solely from the
`
`term "setpoint" or "SP." It would be improper to read into a claim all of the
`
`disclosed operational modes and all disclosed transitions between modes
`
`simply because the claim recites the "setpoint" or "SP."
`
`Patent Owner does not urge that "setpoint" or "SP" requires any
`
`particular transition from mode to mode. Instead, Patent Owner merely
`
`desires to add that a "setpoint" is where a transition between operating
`
`modes "may occur." Id. Nothing of significance is added by that proposed
`
`construction. If a transition is specified by other limitations in the claim, at
`
`9
`
`BMW1012
`Page 1332 of 1654
`
`
`
`IPR2015-00794
`Patent 7,104,347 B2
`
`the setpoint, then a transition is required at the setpoint. If no transition is
`
`specified by other limitations in the claim, then no transition is required at a
`
`setpoint. A transition may or may not occur at a setpoint, depending on
`
`what else is recited in the claim. It is not necessary to include such "may
`
`occur" language in the construction of"setpoint" and "SP." A multitude of
`
`events "may occur" at a setpoint, but they are not necessary for setting forth
`
`the meaning of "setpoint" or "SP" in a claim. The rest of the claim sets forth
`
`what is required to occur at a setpoint.
`
`Nevertheless, we do regard as meaningful to note that nothing in the
`
`Specification precludes a setpoint from being reset, after it has been set. A
`
`setpoint for however short a period of time still is a setpoint.
`
`We construe "setpoint" arid "SP" as "predetermined torque value that
`
`may or may not be reset."
`
`3. "monitor patterns of vehicle operation over time"
`
`Dependent claim 24 recites "monitor[ing]patterns of vehicle
`
`operation over time and vary[ing] said setpoint SP accordingly." Ex. 1401,
`
`60:55-57. Patent Owner argues that we should construe the italicized phrase
`
`to mean ''track and record the driver's repeated driving operations over
`
`time." Prelim. Resp. 12. Petitioner does not provide an explicit construction
`
`for the phrase.
`
`Patent Owner argues that the Specification of the '347 patent's
`
`description of monitoring patterns of vehicle operation over time refers to
`
`how the operator actually drives the car over some period of time, as
`
`opposed to monitoring an internal data point of the vehicle. Id. at 12-16. In
`
`support of its construction, Patent Owner directs attention to the following
`
`descriptions in the Specification:
`
`10
`
`BMW1012
`Page 1333 of 1654
`
`
`
`IPR2015-00794
`Patent 7,104,347 B2
`
`Examples of this practice-amounting in many circumstances
`to modifying certain specific values depending on other data
`items not discussed in detail, or by monitoring the vehicle's
`actual usage patterns over time-are given below.
`Prelim. Resp. 13 (citing Ex. 1401, 35:47-58).
`It is also within the scope of the invention for the
`microprocessor to monitor the vehicle's operation over a period
`of days or weeks and reset this important setpoint in response to
`a repetitive driving pattern. For example, suppose the operator
`drives the same route from a congested suburban development
`to a workplace about the same time every morning; typically
`the road load might remain under 20% of MTO for the first few
`minutes of each day, then vary between O and 50% ofMTO for
`another few minutes as the operator passes through a few traffic
`lights, and then suddenly increase to 150% of MTO as the
`operator accelerates onto a highway. It is within the skill [in]
`the art to program a microprocessor to record and analyze
`such daily patterns, and to adapt the control strategy
`accordingly. For example, in response to recognition of a
`regular pattern as above, the transition point might be adjusted
`to 60% of MTO; this would prevent repetitive engine starts as
`the road load exceeded 30% of MTO for a few hundred yards at
`a time, as might often occur in suburban traffic. Similarly, the
`engine starting routine might be initiated after the same total
`distance had been covered each day.
`Ex. 1401, 40:56-41:9 (emph~is added).
`In addition, Patent Owner, directing attention to external evidence,
`
`argues that the word "pattern" means a regular and repeated course of
`
`conduct or behavior. Prelim. Resp. 16; Ex. 1428; Ex. 2403.
`
`Although Petitioner does not provide an explicit construction for the
`
`phrase "monitor[ing] patterns of vehicle operation over time," P.atent Owner
`
`argues that Petitioner implicitly construes the phrase to encompass
`
`monitoring the battery state of charge or "regenerative charging amount"
`
`11
`
`BMW1012
`Page 1334 of 1654
`
`
`
`IPR2015-00794
`Patent 7,104,347 B2
`
`and adjusting the alleged "setpoint" based on the stored regenerative
`
`charging amount. Id. at 13-14 ( citing Pet. 28-31 ).
`
`We agree with Patent Owner that Petitioner's implicit construction is
`
`not in light of the written description of the Specification of the '347 patent
`
`which describes changing a setpoint in response to monitored vehicle
`
`operation patterns. In particular, the description in the Specification
`
`regarding patterns describes clearly that the patterns are in connection with
`
`the driving patterns of the operator of the vehicle. Ex. 1401, 40:56-41 :9.
`
`The Specification does not describe monitoring "patterns" of a battery state
`
`of charge, for example. Moreover, the plain words of the phrase require
`
`monitoring patterns over time. It is not enough to monitor a single value of
`
`a vehicle component, for instance. Rather the plain meaning of the words
`
`require monitoring patterns, where a pattern is defined as a regular or logical
`
`form, order, etc. Ex. 2403. Thus, we agree with Patent Owner that a pattern
`
`is a regular and repeated course of conduct or behavior and that the phrase
`
`"monitoring patterns of vehicle operation over time" requires monitoring a
`
`driver's repeated driving operations over time.
`
`Accordingly, for purposes of this decision, we interpret "monitoring
`
`patterns of vehicle operation over time" to require monitoring a driver's
`
`repeated driving operations over time.
`
`C. Claims 23, 24, 28, 30, and 32- Obviousness over Jbaraki '882
`Petitioner contends that claims 23, 24, 28, 30, and 32 are unpatentable
`
`under 35 U.S.C. § 103(a) as obvious over Ibaraki '882. Pet. 6-36.
`
`1. Jbaraki '882 (Ex. 1403)
`
`Ibaraki '882 discloses a drive control apparatus for a "hybrid vehicle"
`
`equipped with an electric motor and an internal combustion engine.
`
`12
`
`BMW1012
`Page 1335 of 1654
`
`
`
`IPR2015-00794
`Patent 7,104,347 B2
`
`Ex. 1403, 1: 10--15. The electric motor provides electric energy and operates
`
`as a first drive power source, and the internal combustion engine combusts
`
`fuel to provide a second drive power source. Id. at 2:57-64. The drive
`
`control apparatus includes ( 1) an engine drive mode where the vehicle is
`
`driven by the engine, (2) a motor drive mode where the vehicle is driven by
`
`the electric motor, and (3) an electricity generating mode where an electric
`
`generator is operated by the engine to charge an electric energy storage
`
`device. Id. at 2:64-3:2. Depending on the running condition of the vehicle,
`
`the drive control apparatus selects the drive mode. Id. at 3 :5-14.
`
`2. Analysis
`
`a. Claims 23, 28, 30, and 32
`
`The evidence set forth by Petitioner indicates there is a reasonable
`
`likelihood that Petitioner will prevail in showing that claims 23, 28, 30, and
`
`32 are unpatentable under 35 U.S.C. § 103(a) as obvious over Ibaraki '882.
`
`Pet. 6-36. Petitioner provides a detailed analysis, supported by evidence,
`
`demonstrating that there is a reasonable likelihood that claims 23, 28, 30,
`
`and 32 are obvious over Ibaraki '882. Id.
`
`For example, claim 23 recites a "method of control of a hybrid
`
`vehicle," where the "vehicle comprising an internal combustion engine
`
`capable of efficiently producing torque at loads between a lower level
`
`[setpoint] SP and a maximum torque output MTO." Claim 23 further recites
`
`"the torque produced by said engine when operated at said setpoint (SP) is
`
`substantially less than the maximum torque output (MTO) of said engine."
`
`Claim 23 additionally recites "a battery." Petitioner argues that Ibaraki '882
`
`discloses a drive control apparatus for a hybrid vehicle, where the vehicle
`
`includes an electric motor and an internal combustion engine. Pet. 6-7

`
`(citing Ex. 1403, 1:9-14, 19:11-54; Ex.140811169-170). Petitioner
`
`further argues that Ibaraki '882 discloses an energy efficiency map that
`
`includes a threshold and multiple setpoints based on the engine speed. Pet.
`
`8-9 (citing Ex. 1403, 25:46-26:8, Fig. 5; Ex. 140811 185-187). Petitioner
`
`asserts that the setpoints represent the point where the hybrid vehicle
`
`transitions from motor drive mode to engine drive mode and the engine
`
`efficiently produces torque above the setpoint. Id. Petitioner argues that
`
`lbaraki '882 similarly discloses a drive source selecting data map that
`
`includes a boundary line, along which are setpoints. Id. at 9-10 ( citing Ex.
`
`1403, 20:49-21:20, 24:6-26, Fig. 11; Ex.140811185, 188-190, 193).
`
`Petitioner argues that these setpoints also represent the point where the
`
`hybrid vehicle transitions from motor drive mode to engine drive mode and
`
`the engine efficiently produces torque above the setpoint. Id. Petitioner
`
`explains that although the language "substantially less than" is not
`
`"mathematically precise," 70% of the MTO is "substantially less than" the
`
`MTO and Ibaraki '882 discloses threshold or setpoint at 70% of the engine's
`
`maximum efficiency. Id. at 25-26 (citing Ex. 1403, 25:46-56, Fig. 5).
`
`Petitioner further argues that Ibaraki '882 discloses an energy storage
`
`device, which can be "in the form of a battery or condenser." Id. at 11
`
`(citing Ex. 1403, 19:55-57; Ex 140811198-199) (emphasis omitted).
`
`Claim 23 further recites "one or more electric motors being capable of
`
`providing output torque responsive to supplied current, and of generating
`
`electrical current responsive to applied torque." Claim 23 also recites "said
`
`engine being controllably connected to wheels of said vehicle for applying
`
`propulsive torque thereto and to said at least one motor for applying torque
`
`thereto." Petitioner contends that Ibaraki '882 discloses a "dynamo-electric

`
`
`
`IPR2015-00794

`
`motor" that receives electric energy, i.e. current, from the energy storage
`
`device or battery when in a "DRIVE" state and transfers the power to the
`
`wheels ultimately. Id. at 11-12 (citing Ex. 1403, 19:24-28, 19:55---63; Ex.
`
`14081~ 200-204). Petitioner further contends that Ibaraki '882 discloses a
`
`"CHARGING" state, where the motor functions as an electric generator or
`
`dynamo, with regenerative braking. Id. at 12 (citing Ex. 1403, 19:61---67).
`
`Petitioner argues that Ibaraki '882 discloses that the engine is controlled by a
`
`"clutch." Id. at 12-13 (citing Ex. 1403, 19:50-54, Fig. 8; Ex. 1408 ~1208-
`
`210).
`
`Claim 23 also recites "determining the instantaneous torque RL
`
`required to propel said vehicle responsive to an operator command."
`
`Petitioner argues that Ibaraki '882 discloses a required drive power for a
`
`vehicle that is determined by the vehicle torque and speed. Id. at 13-14
`
`(citing Ex. 1403, 20:39-43, 20:58-21:1, 23:66-24:21; Ex. 1408 ~~ 221-
`
`224). Petitioner further asserts that Ibaraki '882 discloses that the
`
`"instantaneous drive power required for running the vehicle, which power
`
`includes components for overcoming the air resistance experienced by the
`
`vehicle and the rolling resistance of each vehicle wheel." Id. at 14-15
`
`(quoting Ex. 1403, 12:50-54)(emphasis omitted).
`
`Claim 23 additionally recites "monitoring the state of charge of said
`
`battery." Petitioner contends that Ibaraki '882 discloses that the controller
`
`receives a state of charge SOC of the electric energy storage device or
`
`battery. Id. at 16 (citing Ex. 1403, 20:10-23).
`
`Claim 23 further recites four different modes used to propel the
`
`vehicle: ( 1) "employing said at least one electric motor to propel said vehicle
`
`when the torque RL required to do so is less than said lower level SP," (2)
`
`15
`
`BMW1012
`Page 1338 of 1654
`
`
`
`IPR2015-00794
`Patent 7,104,347 B2
`
`"employing said engine to propel said vehicle when the torque RL required
`
`to do so is between said lower level SP and MTO," (3) "employing both said
`
`at least one electric motor and said engine to propel said vehicle when the
`
`torque RL required to do so is more than MTO," and (4) "employing said
`
`engine to propel said vehicle when the torque RL required to do so is less
`
`than said lower level SP and using the torque between RL and SP to drive
`
`said at least one electric motor to charge said battery when the state of
`
`charge of said battery indicates the desirability of doing so." Petitioner
`
`contends that Ibaraki '882 discloses (1) a "MOTOR DRIVE mode," (2) an
`
`"ENGINE DRIVE mode," (3) an "ENGINE-MOTOR DRIVE mode," and
`
`(4) an "ELECTRICITY GENERATING DRIVE mode." Id. at 16-25 (citing
`
`Ex. 1403, 15:37-50, 19:18-27, 19:55-20:9, 20:18-63, 20:43-53, 20:55-
`
`21:1, 23:6-19, 23:66-24:30, 26:18-21, 26:28-33, Figs. 5, 7, 10, 11; Ex.
`1408 ,r,r 242-250, 253-262, 266-281, 287-294). Petitioner further argues
`that Ibaraki '882 discloses (1) the vehicle operates in "MOTOR DRIVE
`
`mode" when the required torque at a given speed is below boundary line B,
`
`(2) the vehicle operates in "ENGINE DRIVE mode" when the required
`
`torque at a given speed is between boundary line B and boundary line C, and
`
`(3) the vehicle operates in "ENGINE-MOTOR DRIVE mode" when the
`
`required torque at a given speed is above boundary line C. Id. Accordingly,
`
`Petitioner asserts that boundary line B is the same as setpoint SP and
`
`boundary line C must be at least equal to the maximum torque output MTO.
`
`Id. Petitioner further argues that Ibaraki '882 discloses that during
`
`"ELECTRICITY GENERA TING DRIVE mode" the engine speed is held
`
`constant at a value greater than the required torque and the surplus torque is
`
`used to drive the motor for charging the battery. Id.

`
`Accordingly, the present record supports that Petitioner has
`
`established a reasonable likelihood it will prevail in demonstrating that claim
`
`23 is obvious over Ibaraki '882. We are similarly persuaded that Petitioner
`
`has established a reasonable likelihood it will prevail in demonstrating
`
`claims 28, 30, and 32 are obvious over Ibaraki '882.
`
`We have considered Patent Owner's argument that the Petition
`
`improperly incorporates arguments and evidence from the Declaration of
`
`Dr. Davis into the Petition. Prelim. Resp. 30-35. We agree that, in general,
`
`arguments must not be incorporated by reference from one document into
`
`another document (37 C.F.R. § 42.6(a)(3)). Here, however, Patent Owner's
`
`arguments are unpersuasive. Petitioner relies on Ibaraki and the knowledge
`
`of POSA in challenging claims 23, 28, 30, and 32. In doing so, Petitioner
`
`relies on Dr. Davis' testimony as evidence of what a POSA would have
`
`known at the time of the invention. We have reviewed those portions of Dr.
`
`Davis' Declaration, to which we are directed, with respect to the grounds
`
`upon which we institute, and, have determined that there is nothing unusual
`
`about his declaration or the way in which Petitioner relies on the declaration
`
`insofar as improper incorporation is concerned, at least not to the extent that
`
`we would disregard the Petition in its entirety. Moreover, we will not
`
`disregard the Petition because of an alleged ''voluminous record." Id. at 34-
`
`35.
`
`Patent Owner also argues that Petitioner has failed to identify "what
`
`claim elements are missing from Ibaraki '882" and, therefore, Patent Owner
`
`argues that Petitioner "fails to provide the requisite Graham v. John Deere
`
`analysis." Prelim. Resp. 36-38. Patent Owner argues that it is unclear
`
`whether Petitioner is asserting that lbaraki '882 discloses the claim element
`
`17
`
`BMW1012
`Page 1340 of 1654
`
`
`
`IPR2015-00794
`Patent 7,104,347 B2
`
`or simple renders obvious the claim element. Id. We are not persuaded by
`
`Patent Owner's argument. Whatever disclosure from each prior art
`
`reference, listed in Petitioner's claim charts in a corresponding location
`
`opposite a reproduced claim limitation, is a representation that that
`
`disclosure meets the associated claim limitation. We have reviewed the
`
`proposed ground of obviousness over Ibaraki '882 against claims 23, 28, 30,
`
`and 32, and are persuaded, at this juncture of the proceeding, that Petitioner
`
`has established a reasonable likelihood that Petitioner would prevail in its
`
`challenge to claims 23, 28, 30, and 32.
`
`Patent Owner also argues that Petitioner relies improperly on two
`
`separate embodiments oflbaraki '882, namely, the disclosures of Figures 5
`
`and 11, and fails to explain why a person of ordinary skill in the art would be
`
`motivated to combine these embodiments. Id. at 38-39. We disagree with
`
`Patent Owner. Petitioner explains that Figures 5 and 11 similarly set forth
`
`thresholds based on engine torque and engine speed. See Pet. 8-10.
`
`Petitioner further sets forth that the thresholds determine the point in which
`
`the engine mode will transition. See id. Although Patent Owner argues that
`
`Figure 5 discloses "thresholds based on engine efficiency" and Figure 11
`
`discloses ''thresholds are based on drive power" (Prelim. Resp. 38-39), we
`
`are not persuaded that these are two separate embodiments. Rather, both
`
`Figures 5 and 11 discloses threshold points for transitioning between engine
`
`modes. The mere fact that Figure 5 also discloses engine efficiency based
`
`on speed and torque does not render it a separate embodiment. Accordingly,
`
`we are not persuaded by Patent Owner that Petitioner has failed to provide
`
`an articulated reasoning with a rational underpinning in supporting its
