`
`INTRODUCTION
`
`Petitioner (“Ford”) requests inter partes review of U.S. Patent No. 7,237,634
`
`(“’634 Patent”, Ex. 1851) through this Petition. The Declaration of Dr. Jeffrey L.
`
`Stein in support of this Petition, is filed as Exhibit 1852 (“Stein”, Ex. 1852).
`
`The ’634 patent is one of five patents that Patent Owner (“Patentee” or
`
`“Paice”) has asserted against Ford in litigation. Paice contends that these patents teach
`
`an allegedly “fundamental” method of “mode control using road load” and “engine
`
`control under which engine torque is above a setpoint.” (Ford Litigation, Ex. 1853 at
`
`16, served on Feb. 25, 2014, id. at 1.) Paice’s methods of using “road load” and an
`
`engine torque “setpoint” were actually well known in the art. (Stein, Ex. 1852, ¶¶63-
`
`68.) U.S. Patent No. 4,335,429 to Kawakatsu (Ex. 1877) and Paice’s own U.S. Patent
`
`No. 5,343,970 (“Severinsky ’970”, Ex. 1854) disclose use of “road load” and “setpoint”
`
`for mode switching in a hybrid vehicle. (Id.)
`
`Paice’s patent claims start with this well-known control strategy and then add
`
`other common features. The ’634 patent has 306 such claims. Ford has repeatedly
`
`asked Paice to limit the asserted claims to a reasonable number (Ford Litigation, Ex.
`
`1853 at 52), but Paice has refused. Accordingly, Ford is filing several IPR’s to address
`
`the ’634 Patent claims and is trying to group the claims according to claimed subject
`
`matter. Due to page limitations, and the voluminous number of dependent claims,
`
`Ford addresses independent claims in multiple petitions. Ford relies on Severinsky
`
`’970 in this petition, but may rely on other references in other petitions because they
`
`1
`
`
`
`address other dependent claims directed toward different subject matter. This IPR
`
`Case No: IPR2015-00801
`Attorney Docket No. FPGP0104IPR8
`
`focuses on claims directed to preheating an engine before it is started.
`
`II. MANDATORY NOTICES UNDER 37 C.F.R. § 42.8
`
`A. Real Party-In-Interest - 37 C.F.R. § 42.8(b)(1)
`
`Petitioner certifies that Ford is the real party-in-interest.
`
`B. Related Matters - 37 C.F.R. § 42.8(b)(2)
`
`The ’634 Patent is being asserted in Paice, LLC and the Abell Foundation, Inc. v.
`
`Ford Motor Company, Case No. 1-14-cv-00492, and Paice LLC and The Abell Foundation,
`

`IV. PERSON OF ORDINARY SKILL IN THE ART (POSA)
`
`The level of ordinary skill in the art is evidenced by the references. See In re
`
`GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995), and is also set forth in the declaration
`
`of Dr. Stein. (Stein, Ex. 1852, ¶¶39-43, see also ¶¶2-11.)
`
`V. OVERVIEW OF THE ’634 PATENT
`
`A.
`
`Purported Improvement in the ’634 Patent
`
`The ’634 Patent identifies a purported “new ‘topology’ for a hybrid vehicle”
`
`requiring “a first electric ‘starting’ motor” and “[a] second ‘traction’ motor . . . directly
`
`connected to the road wheels to propel the vehicle.” (’634 Patent, Ex. 1851, 11:50-61.)
`
`The “new ‘topology’” is disclosed as a two-motor “series-parallel” hybrid. (Id. at 16:5-
`
`4
`
`
`
`Case No: IPR2015-00801
`Attorney Docket No. FPGP0104IPR8
`
`11.) Two-motor “series-parallel” hybrids were well-known long before the earliest
`
`priority date of September 1998. (Stein, Ex. 1852, ¶¶58-59.)
`
`The ’634 Patent also identifies a control strategy to operate the engine, traction
`
`motor, and starter motor “in accordance with the vehicle’s instantaneous torque
`
`demands so that the engine is run only under conditions of high efficiency.” (’634
`
`Patent, Ex. 1851 at 1-Abstract, see also 19:45-50 and 20:61-21:2.)
`
`The control strategy of the ’634 Patent was known in the prior art. (See e.g.,
`
`Stein, Ex. 1852, ¶¶63-68.) In fact, the ’634 Patent acknowledges “the inventive control
`
`strategy according to which the hybrid vehicles of the [’634 Patent] invention are
`
`operated” is the same “as in the case of the hybrid vehicle system shown in the [prior
`
`art Severinsky] ’970 patent.” (’634 Patent, Ex. 1851 at 35:3-9, see also 25:4-24.)
`
`B. The Challenged Claims Require Only One-Motor
`
`The challenged independent claims 267, 241, 80 and 114 each recite “at least one
`
`electric motor.” Accordingly, a hybrid vehicle having only one electric motor satisfies this
`
`limitation; i.e., the challenged claims do not recite the allegedly “novel” hybrid
`
`topology having two-motors disclosed in the ’634 Patent.
`
`VI. STATE AND CONTENT OF THE PRIOR ART
`
`Environmental regulations in the 20th century resulted in the development of
`
`catalysts to increase the rate of fuel combustion to reduce the formation of undesired
`
`emissions. (Stein, Ex. 1852, ¶¶69-78.) Since at least 1988, “three-way” catalysts have
`
`been widely used to control hydrocarbon (HC), carbon monoxide (CO) and nitrogen
`
`5
`
`
`
`Case No: IPR2015-00801
`Attorney Docket No. FPGP0104IPR8
`
`oxide (NOx) emissions. Id. at ¶79. To efficiently convert all three gases, the engine
`
`must operate at a substantially stoichiometric air/fuel ratio. Id. Conventional SI
`
`engines are typically operated with a rich A/F ratio (i.e., non-stoichiometric
`
`combustion) during cold starting conditions to ensure that the engine starts. Id. at ¶84.
`
`However, HC and CO emission levels are high when the A/F ratio is rich. For
`
`example, “[i]t is estimated that cold start-ups are the source of 70--90% of all HC
`
`emissions.” (Pulkrabek, Ex. 1869 at 46; Stein Ex. 1852, ¶84.) It was well known to a
`
`POSA that preheating the engine, before starting the engine, would reduce cold-start
`
`emissions. Id. at 85. A POSA would have also known that when a piston translates
`
`back and forth, it compresses air within the cylinder “raising both the pressure and
`
`temperature in the cylinder.” (Pulkrabek, Ex. 1869 at 16, Stein Ex. 1852, ¶¶46-47.)
`
`Thus, a POSA would have also known that an engine could be preheated, by simply
`
`rotating it for a period of time before starting it. (Id. at ¶¶203-207.)
`
`VII. CLAIM CONSTRUCTION – 37 C.F.R. § 42.104 (B)(3)
`
`For purposes of this IPR, a claim is interpreted by applying its “broadest
`
`reasonable construction.” 37 C.F.R. § 42.100(b).
`
`Petitioner proposes the following claim constructions for the purposes of this
`
`IPR only. But for some terms, based on the specification, file history, and patentee
`
`admissions, Ford contends that construction under applicable district court standards
`
`is narrower, and reserves the right to present a narrower construction in district court
`
`litigation.
`
`6
`
`
`
`Case No: IPR2015-00801
`Attorney Docket No. FPGP0104IPR8
`
`A.
`
`“Road load (RL)” and “RL”
`
`The Eastern District of Texas and Maryland courts have construed the terms
`
`“road load,” “RL,” and “road load (RL)” as “the instantaneous torque required for
`
`propulsion of the vehicle, which may be positive or negative in value.” (Toyota
`
`Litigation, Ex. 1863 at 205-206; Hyundai Litigation, Ex. 1864 at 16, 96-100.)
`
`For this proceeding only, Ford proposes that “road load” be construed as “the
`
`amount of instantaneous torque required to propel the vehicle, be it positive or
`
`negative.” This is consistent with the PTAB’s construction. (See Ford IPRs, Ex. 1865
`
`at 40, 57-58, 70.) Ford contends the construction may be narrower under district
`
`court standards.
`
`B. “Setpoint (SP)” and “SP”
`
`The Texas and Maryland courts construed “setpoint (SP)” as being “a definite,
`
`but potentially variable value at which a transition between operating modes may
`
`occur” (Toyota Litigation, Ex. 1863 at 203-204, Hyundai Litigation, Ex. 1864 at 100-
`
`104.) Ford disagrees that this construction is the broadest reasonable construction.
`
`The ’634 Patent claims, specification, and file history define “setpoint” as a
`
`“predetermined torque value.” All claims recite a “setpoint” or “SP” value being
`
`compared to either: (1) an engine torque value (e.g., claim 1); or (2) a torque-based
`
`“road load” value (e.g., claim 33). No claims recite a “setpoint” or “SP” in comparison
`
`to any other system variable. Likewise, the specification says “the microprocessor tests
`
`sensed and calculated values for system variables, such as the vehicle’s instantaneous
`
`7
`
`
`
`Case No: IPR2015-00801
`Attorney Docket No. FPGP0104IPR8
`
`torque requirement, i.e., the “road load” RL . . . against setpoints, and uses the results of
`
`the comparisons to control the mode of vehicle operation.” (’634 Patent, Ex. 1851,
`
`40:16-26, emphasis added.) To do so (e.g., compare whether “RL < SP”), the “setpoint”
`
`must be in the same measurement units as the “road load.”
`
`During prosecution of the ’347 Patent (Ex. 1866) – the parent of the ’634
`
`Patent – patentee added the following limitation to pending claims 82 and 104, to
`
`overcome a prior art rejection: “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.” Patentee then argued the engine was operated only “when it is
`
`loaded . . . in excess of a setpoint SP, which is now defined to be ‘substantially less
`
`than the maximum torque output (MTO) of said engine.’” (’347 File History, Ex.
`
`1862 at 37-38, 43-44, 49, emphasis added.)
`
`This proposed construction is consistent with the PTAB’s recent construction.
`
`(Ford IPRs, Ex. 1865 at 40-42; see also at 58-60.) Accordingly the broadest reasonable
`
`construction of “setpoint (SP)” and “SP” as used in the challenged claims is a
`
`“predetermined torque value.”
`
`C.
`
`“Mode I,” “low-load operation mode I,” “high-way cruising
`operation mode IV,” “acceleration operation mode V”
`
`8
`
`
`
`Case No: IPR2015-00801
`Attorney Docket No. FPGP0104IPR8
`
`During the Toyota suit, the court construed similar terms1 of the parent ’347
`
`Patent as follows: (1) low-load mode I as “the mode of operation in which energy
`
`from the battery bank flows to the traction motor and torque (rotary force) flows
`
`from the traction motor to the road wheels”; (2) highway cruising mode IV as “the
`
`mode of operation in which energy flows from the fuel tank into the engine and
`
`torque (rotary force) flows from the engine to the road wheels”; and (3) acceleration
`
`mode V as “the mode of operation in which energy flows from the fuel tank to the
`
`engine and from the battery bank to at least one motor and torque (rotary force) flows
`
`from the engine and at least one motor to the road wheels.” (Toyota Litigation, Ex.
`
`1863 at 219.) Ford agrees with these constructions for this IPR but reserves the right
`
`to offer narrower constructions in litigation.
`
`D.
`
`“Abnormal and transient conditions”
`
`The ’634 Patent does not define “abnormal and transient conditions,” nor describe
`
`its full scope with reasonable certainty. Claim 22 of the ’347 Patent, the parent of the
`
`’634 Patent, defines “abnormal and transient conditions” as “comprising starting and
`
`stopping of the engine and provision of torque to satisfy drivability or safety
`
`considerations.” (’347 Patent, Ex. 1866, Claim 22.)
`
`Thus, although Petitioner does not admit that the term “abnormal and transient
`
`
`1 The similar terms of the ’347 Patent do not include the word “operation,” however
`
`the addition of the term does not alter the proposed construction.
`
`9
`
`
`
`Case No: IPR2015-00801
`Attorney Docket No. FPGP0104IPR8
`
`conditions” satisfies 35 U.S.C. § 112, the limitation appears to include “starting and
`
`stopping of the engine and provision of torque to satisfy drivability or safety
`
`considerations.” Accordingly, for purposes of this proceeding only, Petitioner
`
`construes “abnormal and transient conditions” as comprising “starting and stopping of the
`
`engine and provision of torque to satisfy drivability or safety considerations.”
`
`VIII. UNPATENTABILITY GROUNDS
`
`The references below render the claimed subject matter invalid under 35 U.S.C.
`
`§ 103, and the Petitioner therefore has a reasonable likelihood of prevailing on each of
`
`the following grounds of unpatentability. 35 U.S.C. § 314(a); 37 C.F.R. § 42.104(b)(4).
`
`A. GROUND 1: Claims 267, 278-280, 282, 284, 285, 289 and 290 are
`Obvious over Severinsky ’970 in view of Yamaguchi
`
`The purported “new” two motor topology disclosed in the ’634 Patent was an
`
`asserted improvement over the “one motor” hybrid disclosed by Severinsky ’970.
`
`(’634 Patent, Ex. 1866, 11:52, 17:30-36.) Severinsky ’970 and Yamaguchi render
`
`obvious the following one motor claims 267, 278-280, 282, 284, 285, 289 and 290
`
`under §103. (Stein, Ex. 1852, ¶¶128-316.)
`
`1.
`
`Independent Claim 267
`
`Claim 267 is directed to “[a] method for controlling a hybrid vehicle.” Severinsky ’970
`
`illustrates a hybrid vehicle as shown in Figure 3, annotated and reproduced below:
