`C. THE ’828 PATENT
`The ’828 patent, entitled “Vehicle Control,” describes and claims “a
`vehicle control system arranged to control a plurality of vehicle subsystems
`each of which is operable in a plurality of subsystem configuration modes,
`wherein the vehicle control system is operable in a plurality of driving
`modes in each of which it is arranged to select the subsystem configuration
`modes in a manner suitable for a respective driving surface.” Ex. 1001, code
`(54), 2:3–9. The Background of the Invention states that, before the
`invention, “drivers often encounter[ed] a broad range of surfaces and terrains
`in both on-road and off-road settings,” but prior art control systems did not
`allow a driver to “provide direct input regarding the surface terrain” to
`optimize the selection of “appropriate subsystem configuration modes” for
`different terrains. Id. at 1:47–55. The ’828 patent contends that the
`increasingly large number of configuration choices was “complicated and
`confusing” to all but “very experienced” drivers. Id. at 1:36–40. As a result,
`prior art control systems delivered “less than optimal stability, handling, and
`safety performance.” Id. at 1:55–61. Thus, “there [wa]s a need for an
`integrated control system” that “provide[d] improved control of the vehicle
`on a broad range of surfaces.” Id. at 1:57–61.
`The “Summary of Invention” explains that “the present invention
`provides a vehicle control system arranged to control a plurality of vehicle
`subsystems.” Id. at 2:3–5. Figure 4 (reproduced below) shows the vehicle
`control system “controlling the subsystems.” ’828 patent 5:29–30.

`IPR2019-01502
`Patent RE46,828 E
`
`
`
`Figure 4 of the ’828 patent, which is a diagram, shows the
`various controllers and subsystems. Id. at Fig. 4.
`Figure 4 shows driver input device (99), processor based vehicle mode
`controller for providing the appropriate control commands to each
`subsystem controller (98), and a plurality of vehicle subsystems, including
`engine management system 28, transmission controller 30, steering
`controller 48, brakes controller 62, and suspension controller 82. Id. at
`9:44–49.
`
`The ’828 patent also describes other subsystems. For example, the
`’828 patent explains that “[p]referably one of the subsystems comprises a
`differential system operable to provide to a plurality of levels of differential
`lock.” Id. at 2:64–66. “The differential may be a center differential, a front
`differential or a rear differential.” Id. at 3:5-6. The transmission sends drive
`torque to the center differential. Id. at 5:57–60. The center differential then
`transmits drive torque to the front and rear differentials, and the front and
`rear differentials transmit the torque to the front and rear wheels of the car.
`Id. at 5:60–62.
`

`
`
`
`IPR2019-01502
`Patent RE46,828 E
`The ’828 patent describes that the driver rotates rotary knob 99 to
`select one of a plurality of driving modes or surfaces. Id. at 9:59–62. The
`driving modes or surfaces selectable by the driver can include Grass, Sand,
`Rock Crawl and Mud. Id. at 9:59–10:5, 13:19–23, 16:57–59, Fig. 13. Once
`the driver selects a mode, the vehicle controller “controls the configuration
`modes of operation of each of the subsystem controllers.” Id. at 9:43–58,
`2:3–9.
`The ’828 patent describes a vehicle with center, rear, and front
`differentials. Id. at 5:57–63. In this embodiment, transmission controller 30
`controls the transmission ratio of automatic transmission 20, and the
`selection of high or low range in the transfer box 21. Id. at 6:1–3.
`Transmission controller 30 also controls center differential 22 so as to
`control the distribution of drive torque between the front and rear axles, and
`the rear differential 26 so as to control the distribution of drive torque
`between the two rear wheels 13, 14. Id. at 6:3–7. The transmission
`controller 30 could also control the distribution of drive torque between the
`front two wheels 13, 14. Id. at 6:7–9. The ’828 patent explains:
`Center differential 22 and the rear differential 26 each include a
`clutch pack and are controllable to vary the degree of locking
`between a “fully open” and a “fully locked” state. The actual
`degree of locking at any one time is controlled on the basis of a
`number of factors in a known manner, but the control can be
`adjusted so that the differentials are “more open” or “more
`locked.” Specifically the pre-load on the clutch pack can be
`varied which in turn controls the locking torque, i.e. the torque
`across the differential that will cause the clutch, and hence the
`differential, to slip. The front differential could also be
`controlled in the same way.
`Id. at 9:33–43.

`suitable for a respective driving surface,
`[BC.4] and further wherein the plurality of driving modes
`includes at least two off-road modes in which the subsystem
`configurations are controlled in a manner suitable for driving
`on respective off-road driving surfaces, and an on-road mode
`in which the subsystem configurations are controlled in a
`manner suitable for driving on-road,
`and still further, wherein the driver input device comprises a
`selector for selecting the plurality of driving modes in the
`order of the on-road driving mode, a first off-road mode and
`a second off-road mode.
`Id. at 21:33–49 (with labels used by parties added within brackets).8
`II. ANALYSIS
`A. CLAIM INTERPRETATION
`We interpret claims in the same manner used in a civil action under
`35 U.S.C. § 282(b) “including construing the claim in accordance with the
`ordinary and customary meaning of such claim as understood by one of
`
`
`8 Limitations BC.1–BC.4 are found in all of the challenged independent
`claims. See Ex. 1004 ¶ 148. The last limitation and paragraph is not given a
`label by the parties. See Pet. 26.

`ordinary skill in the art and the prosecution history pertaining to the patent.”
`37 C.F.R. § 42.100(b) (2019).9 Only terms that are in controversy need to
`be construed, and then only to the extent necessary to resolve the
`controversy. Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868
`F.3d 1013, 1017 (Fed. Cir. 2017).
`We discern no terms in need of express interpretation to determine
`whether to institute inter partes review. At this stage of the proceeding, we
`merely apply the legal standards set forth above when reading the claims.
`B. LEGAL STANDARDS
`Petitioner challenges the patentability of claims 21, 24, 30, 32–34, 37,
`39, 41–43, 45, and 46 on the grounds that the claims are obvious. Pet. 16–
`67. The Supreme Court in KSR International Co. v. Teleflex Inc., 550 U.S.
`398 (2007), reaffirmed the framework for determining obviousness as set
`forth in Graham v. John Deere Co., 383 U.S. 1 (1966). The KSR Court
`summarized the four factual inquiries set forth in Graham that we apply in
`determining whether a claim is reasonably likely to be unpatentable as
`obvious under 35 U.S.C. § 103(a) as follows: (1) determining the scope and
`content of the prior art, (2) ascertaining the differences between the prior art
`and the claims at issue, (3) resolving the level of ordinary skill in the
`pertinent art, and (4) considering objective evidence indicating obviousness
`
`
`9 On October 11, 2018, the USPTO revised its rules to harmonize the
`Board’s claim construction standard with that used in federal district court.
`Changes to the Claim Construction Standard for Interpreting Claims in Trial
`Proceedings Before the Patent Trial and Appeal Board, 83 Fed. Reg. 51,340
`(Oct. 11, 2018) (to be codified at 37 C.F.R. pt. 42). This rule change applies
`to the instant Petition because it was filed after November 13, 2018. See id.

`or nonobviousness. KSR, 550 U.S. at 406. With these standards in mind, we
`address each challenge below.
`C. PORSCHE 959 (“959 ART”)
`All of the Petitioner’s challenges rely, at least in part, on a group of
`five references related to the Porsche 959, which Petitioner collectively
`refers to as the 959 Art. See Pet. 5. One of the five references is a driver’s
`manual from a Porsche 959 (Ex. 1003), and the remaining four references
`are a four-part magazine article published in a German automotive
`engineering magazine over four months from May to August 1986
`(Exs. 1002A–1002D).10
`The Porsche 959 was a sportscar designed and sold by Porsche in the
`1980s. See Ex. 1002A, 265; Ex. 2026, 2–3 (describing the development of
`the Porsche 959); Ex. 2027, 2 (history of the Porsche 959). The Porsche 959
`was designed to compete in Group B—a rally racing group with a minimum
`production volume of 200 vehicles in any year and weight and tire
`requirements based on engine displacement—and to be used for gathering
`new insights for future Porsche high-performance products. Ex. 1002A,
`265. The Porsche 959 included many auxiliary systems “in order to allow
`drivers to safely, easily and comfortably handle a driving performance that
`had previously only been available in racing vehicles.” Id. at 266. A picture
`of the front-view of the Porsche 959 is reproduced below.
`
`
`
`10 Petitioner includes English translations of the original German magazine
`articles. See Exs. 1002A–1002D. All citations are to the English
`translations. We cite the page numbers in the lower left-hand corner of
`Exs. 1002A–1002D.

`
`
`
`A picture of the front view of a Porsche 959 is reproduced above.
`Ex. 1002A, 265.
`The Porsche 959 includes an electro-hydraulically regulated all-wheel
`drive control system. Ex. 1003, 52. “On the basis of the program selected
`the control unit for all-wheel drive processes engine output, roadwheel speed
`with other variables outputting the values for inter-axle coupling (percentage
`of torque to the front axel) and rear-axle slip limiter (rear limited-slip
`differential).” Id. “The values are passed to electro-hydraulic positioning
`motors which produce the pressures required to compress the plates in [the]
`inter-axle coupling and rear-axle slip limiter.” The Porsche 959 “has four
`programs [“Traction,” “Ice, snow,” “Wet,” and “Dry”] which can be
`selected to suit road conditions or task in hand by moving a stalk on the
`steering column.” Id. The selected program is displayed in the instrument
`panel by illumination of one of the four lights arranged vertically down the
`center of the instrument display as shown in Figure 23 of Ex. 1002B
`(reproduced below).

`Ex. 1002B, 356.
`
`
`D. OBVIOUSNESS OF THE BASE CLAIM LIMITATIONS IN VIEW OF 959
`ART
`Petitioner argues that the teachings of 959 Art render claims 30 and 32
`unpatentable as obvious. Pet. 19–28. In particular, Petitioner argues that the
`959 Art teaches or suggests all of the so-called Base Claim limitations
`(BC.1–BC.4, as labeled in claim 30 above). Id. at 19–26. Patent Owner
`argues, among other things, that the 959 Art fails to describe a vehicle
`control system “arranged to control a plurality of vehicle subsystems,” as
`recited in limitation BC.2 of claim 30. See Prelim. Resp. 14–22. We agree
`with Patent Owner that Petitioner has failed to demonstrate a reasonable
`
`11
`
`
`
`IPR2019-01502
`Patent RE46,828 E
`likelihood of proving that the 959 Art teaches a vehicle control system
`“arranged to control a plurality of vehicle subsystems,” as recited in
`limitation BC.2 of claim 30.
`Petitioner relies on the drive control system of the Porsche 959 as
`teaching the claimed vehicle control system. Pet. 19–20. In particular,
`Petitioner points to the “function drive controller,” the “interaxle
`differential” and “lateral lock” of the Porsche 959 as describing the claimed
`“vehicle control system” and “plurality of vehicle subsystems” recited in
`limitation BC.2. Pet. 19–21. Petitioner asserts that the first subsystem is the
`interaxle differential, which “regulates the amount of torque distributed to
`the front wheels ‘in a plurality of subsystem configuration modes.’” Id.
`at 21 (citing Ex. 1002B, 356; Ex. 1004 ¶ 44). Petitioner submits that “[t]he
`control system adopts a different torque distribution depending on the
`selected driving mode, and other variables such as speed.” Id. (citing
`Ex. 1004 ¶ 45). Petitioner contends the second subsystem is the rear-axle
`slip limiter, for adjusting lateral lock, which “controls a clutch pack
`integrated into the rear axle housing, locking the two rear axles, and forcing
`the rear wheels to spin at the same rate.” Id. at 22 (citing Ex. 1004 ¶ 46).
`Petitioner argues that “[t]he vehicle will adopt a different percentage of lock
`depending on the selected driving mode, and other variables such as speed.”
`Id. at 22 (citing Ex. 1002B, 356). Petitioner submits that “[t]hese
`subsystems are analogous to the center differential and rear differential
`subsystems listed at the bottom of Figs. 5 and 6 in the ’828 patent.” Id. at 23
`(citing Ex. 1004 ¶ 48).
`However, as Patent Owner explains, the center, rear, and front
`differential are treated as a single subsystem in the ’828 patent. See Prelim.
`
`12
`
`
`
`IPR2019-01502
`Patent RE46,828 E
`Resp. 14–22; Ex. 1001, 2:64–66, 3:5–6, 5:57–62, claim 35. Indeed, the ’828
`patent acknowledges that the partial locking of differentials to suit the
`driving conditions was known in the art. See Ex. 1001, 1:33–35. It further
`describes that “one of the subsystems comprises a differential system
`operable to provide a plurality of levels of differential lock, and the
`subsystem configuration modes are arranged to provide different levels of
`said lock.” Id. at 2:64–67. And that “[t]he differential may be a center
`differential, a front differential, or a rear differential.” Id. at 3:5–6; see also
`id. at 9:33–43 (describing the locking of the differentials). We agree with
`Patent Owner, on this record, that all of the examples given in the ’828
`patent treat the differentials as a single subsystem. See Prelim. Resp. 16–17.
`Despite the intrinsic evidence of the patent, neither Petitioner nor its
`declarant provides sufficient explanation why a person of ordinary skill
`would consider the interaxle differential and the lateral lock of the
`Porsche 959 to be separate subsystems as claimed. The Petition provides
`only a conclusion that the interaxle differential and lateral lock of the
`Porsche 959 are separate subsystems, but includes no detailed explanation to
`support that conclusion. Pet. 21 (“The system diagram shows that the two
`subsystems . . . .”). The only evidence that Petitioner cites for its contention
`that the interaxle differential and lateral lock are different “subsystems” is
`the testimony Dr. Glenn R. Bower. See id. at 19 (citing Ex. 1004 ¶ 48). Dr.
`Bower’s testimony on this point is
`The interaxle differential and lateral lock in the Porsche 959 are
`separate subsystems. The ’828 patent specification also treats
`these types of subsystems separately. For example, Figures 5
`and 6 in the ’828 patent distinguish between the center
`differential and rear differential lock subsystems.
`
`13
`
`
`
`IPR2019-01502
`Patent RE46,828 E
`Ex. 1004 ¶ 48. The only distinction between the center and rear differentials
`in Figures 5 and 6 is that they are in different rows in the charts. See
`Ex. 1001, Figs. 5, 6. However, nothing in Figures 5 or 6 states or describes
`each row in the tables as a separate subsystem nor does the related written
`description describe each row as a separate subsystem. See Ex. 1001, 5:31–
`32, 9:65–10:6, Figs. 5, 6. Dr. Bower does not identify any other support for
`his reading of Figures 5 and 6, so we give this testimony no weight. See 37
`C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying
`facts or data on which the opinion is based is entitled to little or no
`weight.”). Moreover, contrary to Dr. Bower’s opinion and as discussed
`above, the ’828 patent refers to the front, center, and rear differentials as a
`single subsystem. Id. at 2:64–66, 3:5–6, 5:57–62, claim 35. The lack of any
`explicit support in Figures 5 or 6 coupled with the express statements in the
`’828 patent lead us to discount Dr. Bower’s conclusory testimony that the
`interaxle differential and lateral lock are separate “subsystems” as claimed.
`See 37 C.F.R. § 42.65(a).
`
`Without a more detailed explanation or additional evidence to support
`its contention that the interaxle differential and lateral lock of the
`Porsche 959 are separate subsystems, we agree with Patent Owner, on this
`record, that Petitioner has failed to show a reasonable likelihood that the 959
`Art accounts for the limitation that the “vehicle controller” is “arranged to
`control a plurality of vehicle subsystems,” as recited in limitation BC.2 of all
`the challenged claims. Petitioner does not rely on any other teachings of the
`959 Art or any other reference to account for this limitation. Accordingly,
`we determine that Petitioner has failed to show a reasonable likelihood that
`claims 30 and 32 are unpatentable as obvious over the 959 Art.

`Patent RE46,828 E
`E. REMAINING CLAIMS AND GROUNDS
`In its challenges to claims 21, 24, 32–34, 37, 39, 41, 42, 45, and 46,
`Petitioner relies solely upon the teachings of the Porsche 959 Art as
`describing the claimed requirement that “the vehicle control system arranged
`to control a plurality of vehicle subsystems each of which is operable in a
`plurality of subsystem configuration modes.” Pet. 29–67. For the reasons
`expressed in Part II.D above, we conclude that Petitioner has failed to
`establish, on this record, that the Porsche 959 Art describes controlling a
`“plurality of subsystems” in the manner required. Accordingly, we
`determine that Petitioner has not demonstrated a reasonable likelihood of
`establishing that claims 21, 24, 32–34, 37, 39, 41, 42, 45, and 46 are
`unpatentable as obvious.
`
`III. CONCLUSION
`For the reasons expressed above, we determine that Petitioner has
`failed to demonstrate a reasonable likelihood of showing that any claim of
`the ’828 patent is unpatentable. Accordingly, we do not institute inter partes
`review of the ’828 patent.
`
`IV. ORDER
`For the reasons given, it is:
`ORDERED that inter partes review is not instituted for any claim of
`the ’828 patent.
