`
`Introduction
`
`Wirtgen failed to meet its burden to show the unpatentability of any claim of
`
`the ’693 patent. Wirtgen’s Reply only underscores the fundamental deficiencies of
`
`its Petition. Rather than respond to the substance of Caterpillar’s arguments, Wirtgen
`
`makes new arguments in violation of the Board’s rules or ignores Caterpillar’s
`
`arguments altogether. But many of Wirtgen’s arguments—including those belatedly
`
`added to its Reply—were recently rejected by the International Trade Commission.
`
`Additionally, as explained throughout, Wirtgen has repeatedly attempted to
`
`circumvent the Board’s type-volume limitations by improperly incorporating large
`
`portions of its expert’s declaration into its reply. In the face of Wirtgen’s new
`
`arguments and attempt to circumvent rules, the Board would be justified in simply
`
`disregarding the Reply in its entirety. Even if the Board considers the substance of
`
`Wirtgen’s reply, however, the Board should adopt Caterpillar’s proposed claim
`
`construction and should reject Wirtgen’s arguments.
`
`II. Claim Construction
`
`
`
`The proper construction of “a retracted position relative to said frame”
`
`requires that the wheel or track be “within the outline of the frame.” Patent Owner
`
`Response at 8. Wirtgen’s reply fails to rebut Caterpillar’s arguments and relies on
`
`an initial decision that the ITC overturned. Wirtgen argues that “[t]he ITC rejected”
`
`Caterpillar’s construction,” but Wirtgen fails to explain that the decision it relied on

`was a non-final ALJ determination. Since then, the Commission vacated the ALJ’s
`
`construction and rejected Wirtgen’s claim construction arguments, finding that the
`
`term “a retracted position relative to said frame” means “a position within or inside
`
`the frame.”1 Commission Opinion2 at 25-26. When properly considered, the
`
`evidence supports Caterpillar’s construction.
`
`A. The ordinary claim language supports Caterpillar’s
`construction
`Caterpillar’s Patent Owner Response explained that the claims set forth a
`
`
`
`dichotomy between positions that project from the frame (a projecting position) and
`
`those that are retracted within the frame (a retracted position). Patent Owner
`
`Response at 8-9. Wirtgen ignores this relationship, proposing an explanation that
`
`gives no meaning to the “projecting” position. Instead, Wirtgen simply argues that a
`
`retracted position is “closer to the frame than the projecting position,” and does not
`
`even attempt to define the projecting position. Petitioner Reply at 1.
`
`
`1 Although the Commission’s construction differs slightly from Caterpillar’s
`
`proposal, Caterpillar does not believe that the scope of the constructions differ.

`
`Case No. IPR2018-01202
`Patent No. 7,140,693
`Wirtgen’s untenable construction is illustrated by the example below, where
`
`
`
`the track is currently outside the machine’s frame in position 1.
`
`
`
`Wirtgen’s construction makes it impossible to determine whether the track in the
`
`figure above is in the retracted or projecting position. Since Wirtgen defines the
`
`“retracted” position only based on the track’s previous position (i.e., whether it was
`
`previously further from the frame), one cannot determine whether this track meets
`
`the claim limitation.
`
`
`
`Further adding to the uncertainty, Wirtgen’s construction permits a position
`
`to be both projecting and retracted. If the track could extend further from the frame

`

`Patent No. 7,140,693
`to position 2, as shown below, position 1 would be a retracted position under
`
`Wirtgen’s construction, since it is closer to the frame than the position 2.
`
`
`
`That same position, however, could also be a projecting position under Wirtgen’s
`
`construction. If the track could be drawn closer to frame, to position 3, the same
`
`position 1 would be “projecting” since it was further away from the frame than this
`
`new position.

`
`
`
`This uncertainty in Wirtgen’s argument eliminates the distinction between the two
`
`positions and renders them meaningless.
`
`
`
`The Commission also identified this flaw in Wirtgen’s construction. When
`
`reversing the ALJ’s claim construction decision, the Commission found that, “In
`
`effect, the [ALJ] construes the retracted position to be relative to the projecting
`
`position whereas the claim language requires ‘a projecting position and a retracted
`
`position relative to said frame.’ In other words, the point of reference in claim 1 for
`
`the two positions in which the wheels or tracks may pivot is the ‘frame’ whereas the
`
`[ALJ]’s point of reference is the projecting position.” Commission Opinion at 20-
`
`5
`
`
`
`
`
`
`
`

`

`21. The Board should reject Wirtgen’s construction for improperly shifting the
`
`claim’s point of reference.
`
`
`
`In contrast, Caterpillar’s construction consistently uses the correct point of
`
`reference: the frame. A projecting position relative to the frame is a position that
`
`projects from the frame. In contrast, positions that do not project from the frame are
`
`retracted positions (those retracted within the frame). This construction is consistent
`
`with the claim language and should be adopted.
`
`The specification supports Caterpillar’s construction.
`B.
`The specification also supports Caterpillar’s construction. The patent’s
`
`
`
`discussion of the prior art, its equating of “retracted” with “interior,” and the patent’s
`
`figures all demonstrate that “retracted” means within the outline of the frame.
`
`
`
`Wirtgen’s reply ignores this evidence and instead sets up a strawman to
`
`support its construction. Wirtgen argues that the specification never equates the term
`
`“relative to” with “within” or “inside” the frame. Petitioner Reply at 3. But
`
`Caterpillar never suggested that the patent equates these terms.3 Instead, the patent
`
`clearly equates “exterior” with “projecting” and “interior” with “retracted,” stating
`
`
`3 Wirtgen similarly relies on other references to the term “relative” in the patent, but
`
`Wirtgen ignores the patent’s discussion of the retracted and projecting positions. See
`
`Petitioner Reply at 3-5.

`
`Case No. IPR2018-01202
`Patent No. 7,140,693
`that “a rear support wheel [] can be pivoted between an interior or retracted position
`
`and an exterior or projecting position.” Ex. 1001 at 1:57-60 (emphasis added); see
`
`also Patent Owner Response at 9. While Wirtgen attempts to dismiss these terms as
`
`“alternatives,” the patent clearly gives these terms the same meaning by
`
`acknowledging that they are synonymous. The Commission agreed with Caterpillar,
`
`noting that “portions of the specification . . . equate ‘retracted’ with ‘interior’ or
`
`‘inside’ the frame.” Commission Opinion at 21. Furthermore, the Commission found
`
`that, “it appears that the patentee is equating ‘interior’ with ‘retracted’ and ‘exterior’
`
`with ‘projecting.’” Id. 22.
`
`
`
`The patent figures and discussion consistently depict the retracted position as
`
`within the frame. The patent further supports supporting Caterpillar’s position by
`
`expressly acknowledging that the “retracted position allows the work machine to
`
`operate flush to a wall or curb.” Ex. 1001 at 1:48-52. While Wirtgen argues that
`
`“flush milling” is not a claim limitation, the discussion still provides context to the
`
`meaning of the term retracted position. The Commission explained that this
`
`discussion showed that, “the wheels or tracks in a retracted position cannot project
`
`away from the frame, . . . because such position does not allow the machine to
`
`operate flush to a wall or curb.” Commission Opinion at 21.
`
`
`
`Wirtgen failed to provide a single citation from the patent specification
`
`indicating that a retracted position can be outside the frame. It is little surprise, then,

`13490
`
`Case No. IPR2018-01202
`Patent No. 7,140,693
`that the Commission found that Wirtgen “identified no instance in the record where
`
`‘a retracted position relative to said frame’ refers to a position that is not inside or
`
`within the frame.” Id. at 25.
`
`C. The prosecution history supports Caterpillar’s
`construction.
`The prosecution history also supports Caterpillar’s construction. During
`
`
`
`prosecution the applicant distinguished prior art by arguing that a reference did not
`
`have a retracted position because its wheel did not retract “within the chassis.” Ex.
`
`1002 at 100. In full, the applicant argued:
`
`Kaiser does not disclose the ability to retract any of the wheels or tracks
`relative to the chassis. At best, Kaiser discloses moving the wheel to a position
`where they are roughly parallel with the side of the chassis and always far in
`front of or behind the chassis, but never retracted relative to the chassis, as
`claimed by the applicant (“a retracted position relative to said frame”). This
`feature of retracting a wheel or track to a position within the chassis is
`desirable in the case of a road mill, but would not be used or considered for
`use in a machine of the store described by Kaiser.
`
`Id.
`
`
`
`Wirtgen argues that the “applicant’s argument regarding Kaiser [was] distinct
`
`from Caterpillar’s argument here”—that the wheel was kept “about the same
`
`distance away from the chassis.” Petitioner Reply at 5. While the applicant explained
`
`that Kaiser lacks a retracted position because the wheel is “roughly parallel,” it
`
`8
`
`
`
`
`
`
`
`

`

`Case 1:17-cv-00770-JDW-MPT Document 120-17 Filed 11/17/22 Page 14 of 36 PageID #:
`13491
`
`Case No. IPR2018-01202
`Patent No. 7,140,693
`further explained what was required to have a retracted position—that the wheel
`
`move “within the chassis.” Ex. 1002 at 100 (emphasis). Though Wirtgen ignores this
`
`statement, the Commission found it persuasive, noting that “the patentee expressly
`
`stated that an embodiment having the support arm and wheel at a position roughly
`
`parallel with the side of the frame is not ‘a retracted position relative to said frame,’
`
`and that a feature of the invention is to retract the wheel or track to a position within
`
`the frame.” Commission Opinion at 24. This showed that “the patentee understood,
`
`and the Examiner agreed,4 that the term . . . means a position where the wheel or
`
`track is within or inside the frame.” Id. The applicant’s statements during
`
`prosecution show that it understood the retracted position in a manner squarely
`
`consistent with Caterpillar’s construction.
`
`
`
`Wirtgen next argues that the applicant’s argument “do[es] not support
`
`Caterpillar’s construction” because the applicant also presented “other arguments
`
`relating to Kaiser,” but this is contrary to law. The Federal Circuit has repeatedly
`
`“made clear [that] an applicant’s argument that a prior art reference is
`
`distinguishable on a particular ground can serve as a disclaimer of claim scope even
`
`if the applicant distinguishes the reference on other grounds as well.” Saffran v.
`
`
`4 The Commission noted that in the subsequent Office Actions, the Examiner did not
`
`restate the rejection based on Kaiser. Commission Opinion at 24.

`
`Case No. IPR2018-01202
`Patent No. 7,140,693
`Johnson & Johnson, 712 F.3d 549, 559 (Fed. Cir. 2013). Thus, simply because the
`
`applicant made other arguments against Kaiser does not diminish the fact that the
`
`patentee clearly set forth its understanding of the retracted limitation.
`
`
`
`Finally, Wirtgen argues Caterpillar’s construction should be rejected because,
`
`during prosecution, the applicant did not argue that the Gutman reference lacked a
`
`retracted position. As the Commission rightly found, this is a specious argument:
`
`[Wirtgen’s] argument makes little sense because Gutman was not used by the
`Examiner to establish that it discloses “a retracted position relative to said
`frame” so the patentee would not be expected to respond that Gutman does
`not disclose that element. . . . It would be immaterial for the patentee to argue
`that Gutman does not disclose “a retracted position relative to said frame”
`when the Examiner made no such assertion . . . .
`
`Commission Opinion at 25-26. Indeed, Wirtgen argued that this IPR should be
`
`instituted in part because, “the Examiner considered only whether a POSITA would
`
`combine Gutman’s teaching of a second actuator for rotating a wheel with Simons.”
`
`Paper No. 9 at 9 (emphasis added). Thus, Wirtgen acknowledged that the Examiner
`
`did not rely on Gutman for the retracted position limitation. Like the claim language
`
`and the specification, the prosecution supports only Caterpillar’s construction.
`
`D. Extrinsic evidence supports Caterpillar’s construction.
`The extrinsic evidence also supports Caterpillar’s position. For example the
`
`
`
`Bitelli ’037 and Busley references use the term “retracted” to refer to a position
`
`10
`
`
`
`
`
`
`
`

`

`Case 1:17-cv-00770-JDW-MPT Document 120-17 Filed 11/17/22 Page 16 of 36 PageID #:
`13493
`
`Case No. IPR2018-01202
`Patent No. 7,140,693
`within the frame. See, e.g., Ex. 1011 at ¶¶ 7-9; Ex. 1017 at Fig. 1, 7. As with the
`
`’693 patent, Wirtgen does not identify even one instance where any reference refers
`
`to a position outside the frame as a “retracted” position. Thus, like the ’693 patent,
`
`the extrinsic evidence shows that the industry uniformly refers to a retracted position
`
`as one inside the frame.
`
`
`
`Second, Wirtgen attempts to rebut Caterpillar’s use of dictionary definitions,
`
`arguing that to “‘[d]raw or pull (a thing) back in’ . . . does not require the ‘thing’ to
`
`be drawn in beyond some arbitrary boundary.” Petitioner Reply at 7. But the
`
`definition itself states that retract means to draw or pull something “back in.” Ex.
`
`2006 at 4-5. Wirtgen’s argument stems from its disregard for the ’693 patent’s
`
`distinction between projecting and retracted positions with reference to the frame.
`
`
`
`Notably, Wirtgen again ignores the evidence showing the distinction between
`
`“retracted” and “projecting.” Caterpillar showed “project” is defined as “protruding”
`
`or to “cause to jut or stand out.” Id. at 3. Wirtgen ignores this evidence, failing to
`
`even attempt to reconcile its construction with the dictionary. Wirtgen ignores all
`
`evidence demonstrating that, unlike the retracted position, a projecting position must
`
`“jut or stand out” from the frame. Id.
`
`
`
`The evidence uniformly supports Caterpillar’s construction that the retracted
`
`position is within the frame. Unlike Wirtgen’s construction, Caterpillar’s position is
`
`consistent with the record and should be adopted.

`III. The Combination of Gutman and Bitelli Does Not Render the
`Claims Obvious
`
`
`
`Wirtgen’s proposed combination of Gutman and Bitelli fails to render obvious
`
`any challenged claim. Despite relying on never-before-presented arguments,
`
`Wirtgen’s Reply fails to remedy the significant deficiencies in this combination.
`
`Indeed, the Commission recently rejected many of these same arguments. The Board
`
`should similarly find the challenged claims valid here.
`
`A. Gutman and Bitelli do not render obvious “a retracted
`position relative to said frame.” (Claims 1, 17, 36, and 38)
`Gutman does not disclose a retracted position relative to said frame. While,
`
`
`
`Wirtgen presents new arguments in an attempt to salvage its Petition, none of them
`
`has merit.
`
`
`
`While Gutman can vary its tracks’ distance from its frame, its tracks always
`
`project relative to the frame, as shown in the below annotated figure. Patent Owner
`
`Response at 23.

`“frame assembly 12” as satisfying the “frame” limitation. Petition at 26; Ex. 1003,
`
`¶77. In fact, Wirtgen’s Petition annotated an image of Gutman’s machine showing
`
`that it relied on the frame 12—the same component that Gutman identifies as the
`
`frame:

`Wirtgen never identified these features as satisfying the “frame” limitation and for
`
`that reason alone its reply is improper. See Trial Practice Guide (August 2018
`
`update) at 14 (“Petitioner may not submit new evidence or argument in reply that it
`
`could have presented earlier”).
`
`
`
`But even under Wirtgen’s new argument, Gutman fails to meet the retracted
`
`position limitation. Regarding the side portion of the rotary cutter, other figures
`
`clearly identify it as part of rotary cutter 30, not the frame:

`Id. at Fig. 4 (annotated). Moreover, simply because Gutman states that the cutter is
`
`fixed to the frame does not mean that the side of the cutter is part of the frame.
`
`Indeed, the image Wirtgen previously relied on shows the cutter’s connection to the
`
`frame 12—the very same frame that Wirtgen previously relied on:
`
`
`
`Id. at Fig. 1 (annotated). There is no support for Wirtgen’s new argument that the
`
`cutter should be considered part of the frame.
`
`
`
`Finally, Wirtgen also argues that the “storage tank” should be considered part
`
`of the frame, but Wirtgen provides no reasoning or explanation for this new
`
`argument. Wirtgen has simply identified the widest portions of Gutman’s machine
`
`and argued, without support, that they should be considered part of the frame. Not
`
`only is this an improper, new argument in its Reply, but it is also meritless. Indeed,
`
`in response to the same arguments by Wirtgen, the Commission agreed with
`
`Caterpillar that Gutman does not contain a “retracted position relative to said frame.”

`
`Case No. IPR2018-01202
`Patent No. 7,140,693
`Commission Opinion at 44-46. The Commission found that “Gutman, like Kaiser,
`
`discloses a machine wherein the wheel or track is parallel to the frame rather than at
`
`a position within or inside the frame.” Id. at 45. The Board should reject Wirtgen’s
`
`argument here as well.
`
`B. Gutman and Bitelli do not render obvious “the projecting
`and retracted position forming an arc of at least 90º.” (Claim
`17)
`The combination of Gutman and Bitelli does not render obvious “the
`
`
`
`projecting and retracted position forming an arc of at least 90º.” It is undisputed that
`
`Gutman does not mention such a feature. Additionally, a primary goal of Gutman’s
`
`design is to increase the machine’s stability. As Caterpillar explained, moving
`
`Gutman’s track through an arc of at least 90 degrees would undermine this goal.
`
`Wirtgen does not dispute this. Instead, Wirtgen proposes brand-new modifications
`
`to the prior art while ignoring Caterpillar’s stability analysis. Wirtgen’s
`
`unpatentability arguments ignore Gutman’s fundamental goal, and the Board should
`
`reject them.
`
`1. Gutman does not disclose the claimed 90º arc
`Wirtgen argues the Gutman “teaches or suggests” the claimed 90-degree arc,
`
`
`
`but Wirtgen fails to provide any support for Gutman achieving such an arc. See
`
`Petitioner Reply at 11-14. Instead, Wirtgen argues that Gutman “does not limit its
`
`teachings” to the embodiment disclosed in the reference. Id. at 11. But nothing in

`
`Case No. IPR2018-01202
`Patent No. 7,140,693
`the reference indicates that Gutman’s arms were intended to move through such an
`
`arc. On the contrary, Gutman states that it intends its tracks to move to increase
`
`stability by “increas[ing] the distance between the tracks.” Ex. 1005 at 3:35-54.
`
`Caterpillar’s expert demonstrated that moving Gutman’s track through an arc of at
`
`least 90 degrees would decrease the distance between Gutman’s tracks, lowering its
`
`stability. Ex. 2008 at ¶ 129. Wirtgen has not disputed this and has identified no
`
`reason why Gutman “teaches or suggests” a feature that would work against the very
`
`stability principle it discloses.
`
`2.
`
`A POSITA would not have been motivated to modify
`Gutman to move its tracks through an arc of at least
`90º
`Recognizing that Gutman does not support its argument, Wirtgen next argues
`
`
`
`that a POSITA would have instead been motivated to modify the reference so that
`
`its support arm pivots more than 90 degrees. See Petitioner Reply at 12. In support
`
`of this argument, Wirtgen 1) relies on additional references without considering
`
`them in light of Gutman’s disclosure, 2) identifies a different actuator not mentioned
`
`in any reference, and 3) provides conclusory arguments regarding stability without
`
`even evaluating the analysis of Caterpillar’s expert. Each of these arguments is
`
`meritless.
`
`
`
`First, Wirtgen identifies Bitelli and Hudis as examples of references that
`
`would provide “reasons for pivoting the support arms over 90 degrees.” PR, 12. But,
`
`18
`
`
`
`
`
`
`
`

`

`Case 1:17-cv-00770-JDW-MPT Document 120-17 Filed 11/17/22 Page 24 of 36 PageID #:
`13501
`
`Case No. IPR2018-01202
`Patent No. 7,140,693
`Wirtgen does not explain how they would inform a POSITA regarding Gutman’s
`
`machine and Wirtgen provides no motivation to combine the teachings of these
`
`references with Gutman.
`
`
`
`Wirtgen fails to address the fact that Gutman states that its tracks are movable
`
`to increase the distance between the tracks, but it is undisputed that the Wirtgen’s
`
`proposed modification would decrease those distances and the machine’s stability.
`
`See Ex. 2008 at ¶ 129 (constituting the only testimony on this issue). Wirtgen
`
`presented no reason why a POSITA would use Hudis and Bitelli to modify Gutman
`
`in a manner contrary to Gutman’s own disclosure. The ALJ and Commission agreed
`
`with Caterpillar that a POSITA would not have undertaken this modification, relying
`
`on testimony that “extending Gutman’s legs beyond 90 degrees would not improve
`
`the machine because it would actually begin to reduce track width and decrease
`
`stability.” Ex. 2005 at 57.5
`
`
`
`Second, Wirtgen introduces a new reference to argue that a POSITA knew of
`
`telescoping cylinders. Petitioner Reply at 12. Initially, the Board need not even
`
`consider Wirtgen’s improper effort to introduce new references to backfill gaps in
`

`determination).

`13502
`
`Case No. IPR2018-01202
`Patent No. 7,140,693
`the prior art. See Trial Practice Guide at 15 (noting the impropriety of relying on
`
`“newly cited prior art references intended to ‘gap-fill’ by teaching a claim element
`
`that was not present in the prior art presented with the petition.”). But putting aside
`
`the impropriety of the argument, Wirtgen fails to explain this reference’s relevance.
`
`Gutman does not mention telescoping cylinders. Wirtgen does not even argue that a
`
`POSITA would have used that type of cylinder in Gutman or explain why one would
`
`have been motivated to use such a cylinder. In short, this new reference does not
`
`support Wirtgen’s argument.
`
`
`
`Finally, Wirtgen argues that Caterpillar’s expert’s analysis should be
`
`disregarded because the ground incline may not be level, but Wirtgen based its
`
`argument on the incorrect assumption that Dr. Singhose’s analysis only applies to
`
`relatively level ground. Dr. Singhose presented calculations analyzing the conditions
`
`under which Gutman would be prone to tip over. Ex. 2008, ¶¶109-123. During his
`
`deposition, he explained that his calculations would apply not only to flat surfaces
`
`but also to a range of angles due to the effect of “cosineθ.” Ex. 1024, 67:22-69:13.
`
`
`
`As Dr. Singhose explained, to convert the results of his calculations to apply
`
`to any angle of incline, one would simply adjust his results by taking cosineθ into
`
`account. Ex. 1024, 68:7-16, 69:6-13. He explained that the cosineθ remains near 1
`
`for relatively small angles. Id. (“But cosine theta . . . stay[s] pretty constant for low
`
`angles.”; “Cosine of the slope angle theta . . . stays near one for quite a while as the

`angle changes.”). The following chart shows that cosineθ stays constant for a range

`
`Value of the Cosineθ
`
`Dr. Singhose’s calculations would, therefore, remain constant for a range of degrees.
`
`For example, at 8 degrees the cosineθ equals 0.990. To account for this angle, one
`
`would simply need to multiply Dr. Singhose’s final moment calculation by the
`
`cosineθ value, in this case 0.990. Doing so would yield a result nearly identical to
`
`the “large value that indicates the machine is very stable.” Ex. 2008, ¶123. Therefore,
`
`Dr. Singhose’s conclusion—that the Gutman machine is very stable—applies to a
`
`large range of angle measurements.
