`I, Thomas von Alten, declare:
`
`1.
`
`I have been retained by Wolf, Greenfield & Sacks, P.C., counsel for
`
`Petitioner Sony Corporation (“Petitioner” or “Sony”), to submit this reply
`
`declaration in connection with Sony’s Petition for Inter Partes Review of Claims 1-
`
`4 of U.S. Patent No. 6,462,905 (“the ’905 patent”).
`
`2.
`
`I am being compensated for my time at a rate of $250.00 per hour, plus
`
`actual expenses. My compensation is not dependent in any way upon the outcome
`
`of this proceeding.
`
`3. My background is provided in my earlier declaration (Ex. 1004), and
`
`that declaration also contains my opinions concerning the patentability of claims 1-
`
`4 of the ’905 Patent. I understand that Fujifilm subsequently disclaimed claim 4.
`
`4.
`
`In preparing this reply declaration, I was asked to evaluate and respond
`
`to certain opinions that Mr. William Vanderheyden provided in a statement (Ex.
`
`2008) that Fujifilm submitted in this proceeding.
`
`I.
`
`1: THE MCALLISTER-I AND LAVERRIERE
`GROUND
`COMBINATION RENDERS CLAIMS 1-2 OBVIOUS
`As set forth in my opening declaration, a person of ordinary skill in the
`5.
`
`art (“POSA”) would have had reasons to add the “centering ribs” of Laverriere to
`
`the cartridge depicted in McAllister-I. The resulting McAllister-I / Laverriere
`
`combination would have included every element of claims 1 and 2.
`
`
`

`

`

`A. McAllister-I Exhibits the Same Potential for Brake
`Misalignment that Motivated Laverriere’s Centering Ribs
`As explained in my opening declaration, Laverriere explains that
`
`6.
`
`centering ribs are helpful because clearances between a braking member and the
`
`components with respect to which it moves inside a tape cartridge create the potential
`
`for the braking member to become “misaligned…during assembly and/or use.” Ex.
`
`1004 ¶158; Ex. 1007 at 1:31-39.
`
`7.
`
`The same is true of McAllister-I. For example, as I previously
`
`explained, in McAllister-I there must be clearance between the outer circumference
`
`of the locking gear 42 (braking member) and the inner surface of the reel hub 32 to
`
`ensure undisturbed rotation of the reel as tape is wound or unwound. Ex. 1004 ¶161.
`
`Likewise, as I also previously explained, in McAllister-I there must be clearance
`
`between mating components 58 and 60 that attach the braking member to the top
`
`portion of the cartridge shell because these components move up and down relative
`
`to one another when the braking member moves up and down to unlock and lock the
`
`reel. Ex. 1004 ¶162; McAllister-I at Fig. 3.
`
`8. Mr. Vanderheyden disagrees and states that “a person of ordinary skill
`
`in the art would not identify a misalignment problem in McAllister-I.” 2008 ¶130.
`
`Mr. Vanderheyden is incorrect.
`
`
`
`- 2 -
`
`

`

`1.
`
`A POSA Knew There Must Be Clearance Between
`McAllister-I’s Locking Gear and Reel Hub
`9. Mr. Vanderheyden states that “a POSA would not assume that
`
`clearance exists between elements, if such a clearance or spacing is not explicitly
`
`shown in the figures” of McAllister-I. Ex. 2008 ¶133. He then argues that there
`
`could be a “line-to-line” fit (i.e., no clearance at all) between McAllister-I’s locking
`
`gear 42 (braking member) and the inner surface of its reel hub 32. Id. This, of
`
`course, is impossible as I explained in my opening declaration, because the reel of
`
`such a cartridge rotates at speeds of more than 2,000 rpm and is expected to last for
`
`years. Were the locking gear 42 and the inner surface of the reel hub 32 in contact
`
`with each other, operation of the cartridge would be impossible. Indeed, in an earlier
`
`section of his declaration, Mr. Vanderheyden admitted that McAllister-I is designed
`
`to have clearance between these components: “The male and female interlocking
`
`structures were designed with a tight fit1 to prevent the braking member from
`
`touching the inner wall of the reel hub, without obstructing the intended up and
`
`down movement of the braking member.” Ex. 2008 ¶69 (emphasis added).
`
`
`1 I will address Mr. Vanderheyden’s incorrect analysis of the interlocking structures
`
`(i.e., mating elements 58 and 60) separately in the next section of this declaration.
`
`
`
`- 3 -
`
`

`

`10. While McAllister-I does not include the sort of orthogonal cross-
`
`section views that would most clearly depict clearance between locking gear 42 and
`
`the inner surface of the reel hub 32 (i.e., the kinds of images that Mr. Vanderheyden
`
`admits allow the viewer to clearly see such clearance in Laverriere, Ex. 2008 ¶104),
`
`a POSA reading McAllister-I and understanding typical cartridge design would
`
`readily have understood that such clearance certainly exists for multiple reasons.
`
`11. First, as noted above, Mr. Vanderheyden’s hypothetical alternative, in
`
`which there is a “line-to-line” fit (i.e., no clearance) between the braking member
`
`and the inner surface of the reel hub, is not practical. Any contact between moving
`
`parts during operation – let alone a reel spinning at 2,000 rpm – would create
`
`vibration and friction. Vibration in the tape path would interfere with the very
`
`sensitive operation of a magnetic tape drive reading and writing system. Friction in
`
`turn creates heat and the potential for damage to either the cartridge or the magnetic
`
`tape. No POSA would ever consider it a viable design to use a “line-to-line” fit,
`
`with no clearance, between the braking member and the inner surface of the reel hub.
`
`12. Second, the prior art consistently depicts clearance between the braking
`
`member and the inner surface of the reel hub. E.g., Ex. 1006 (Mizutani) at FIG.1;
`
`Ex. 1007 (Laverriere) at FIGS. 2 & 3; Ex. 1010 (Morita-I) at FIG. 1; Ex. 1011
`
`(Morita-II) at FIGS. 4, 7, 9, 10, 12, 14; Ex. 1012 (Tsuyuki) at FIG. 1; Ex. 1027
`
`(ECMA-210) at 22 (FIG. 13), Ex. 1028 (ECMA-196) at 28 (FIG. 16), Ex. 2002
`
`
`
`- 4 -
`
`

`

`(Shima) at FIG. 2(b), Ex. 2017 (Imation patent publication) at FIGS. 1-3. The
`
`uniformity of the prior art on this point confirms that Mr. Vanderheyden’s
`
`hypothetical alternative “line-to-line” fit (i.e., no clearance) between the braking
`
`member and the inner surface of the real hub is not how a POSA would have
`
`understood McAllister-I’s components to be sized.
`
`13. The prior art listed in the prior paragraph includes both references
`
`describing LTO-style cartridges (e.g., Mizutani, Morita-II, Shima, Tsuyuki) and
`
`earlier-generation products embodying IBM 3480-style cartridge designs (e.g.,
`
`Laverriere, Morita-I, ECMA-210, ECMA-196, Imation patent publication).
`
`14.
`
`In an attempt to suggest that McAllister-I should be interpreted as
`
`lacking any clearance between the braking member and the inner surface of the reel
`
`hub, Mr. Vanderheyden tries to differentiate between the braking members in LTO-
`
`style cartridges and those in 3480-style cartridges. For example:
`
`• “The projecting means of Laverriere were intended to address unique issues
`
`with respect to the Laverriere brake button cartridge design, which included a
`
`large space between the brake button and the inner wall of the reel hub.
`
`McAllister-I, on the other hand, specifically criticized and rejected the exact
`
`cartridge design used by Laverriere.” Ex. 2008, ¶128.
`
`
`
`- 5 -
`
`

`

`• “To help overcome the above disadvantages associated with the 3480-type
`
`magnetic tape cartridge, future generations of tape cartridges stopped using
`
`brake buttons altogether…LTO cartridges moved away from the brake button
`
`of the 3480-type cartridge, and instead utilized a completely different braking
`
`mechanism known as an LTO reel lock mechanism, also referred to as an
`
`alternative reel lock mechanism.” Id., ¶65.
`
`15.
`
`In fact, however, the braking members in LTO-style cartridges and
`
`3480-style cartridges are virtually identical. As shown below, all comprise
`
`(proceeding from top to bottom) an upward facing element that mates with a
`
`downward-facing element on the top shell of the cartridge, a downward-facing gear
`
`for locking the reel, and a downward-facing area in the middle of the braking
`
`member to receive an upward force causing the braking member to disengage from
`
`the reel so that the reel can rotate. The difference between the 3480-style design and
`
`the LTO-style design lies not in the braking member, but in the element that actuates
`
`(pushes up on) the braking member to disengage it from the reel. In 3480-style
`
`cartridges, a chucking member in the drive unit presses up directly on a central
`
`portion of the braking member (referred to as the “brake button”2), while in LTO-
`
`
`2 Sometimes the prior art uses a shorthand in which the entire 3480 braking member
`
`is referred to as a “brake button” – a phrase Mr. Vanderheyden repeats many times
`
`
`
`- 6 -
`
`

`

`style cartridges, the chucking member pushes up, in three equidistant locations,
`
`against the legs of an intermediate element called a spider washer, which in turn
`
`presses up on a central portion of the braking member.
`
`McAllister-I, FIG. 2B
`
`Morita-I, FIG. 1
`
`
`
`
`
`
`
`
`
`in his statement in an apparent effort to make the 3480-style braking member sound
`
`different from the LTO-style braking member – but in fact the “button” is simply the
`
`portion of the braking member against which the drive unit chuck pushes. A more
`
`accurately descriptive name for the part as a whole is “braking member.”
`
`
`
`- 7 -
`
`

`

`16. That difference (i.e., imposition of a spider washer between the drive
`
`unit’s chucking member and the braking member in the LTO design) has nothing to
`
`do with the shape or diameter of the braking member. As shown in orthogonal cross-
`
`section figures in Mizutani and Morita-II, LTO-style cartridges certainly had
`
`clearance between the braking member and the inner surface of the hub.3 Indeed,
`
`ECMA-319, the standard that the LTO consortium prepared in the late 1990’s and
`
`published in 2001, clearly shows such clearance (highlighted in Figure 10 below).4
`
`
`3 Mr. Vanderheyden’s suggestion that the “new more efficient release mechanism
`
`[of LTO] also obviated the need for the ‘significantly’ different diameters between
`
`brake button and hub” (Ex. 2008 ¶153) is nonsensical because, as described already,
`
`the imposition of a spider washer in the LTO design had no impact on the braking
`
`member. Unsurprisingly, Mr. Vanderheyden cites not a single document (let alone
`
`a prior art document) describing an LTO cartridge as lacking clearance between the
`
`braking member and the inner surface of the hub.
`
`4 As I have previously mentioned, I was intimately involved in development of the
`
`mechanical design for the LTO cartridge on behalf of HP (one of the three members
`
`of the LTO consortium) and I prepared the drawings of the cartridge that appear in
`
`the ECMA-319 standard.
`
`
`
`- 8 -
`
`

`

`
`
`Ex-1034 at 28.
`
`17.
`
`Indeed, the ’905 patent itself (which purports to describe features of
`
`LTO-style cartridges) describes and even claims the existence of clearance between
`
`the braking member and the inner surface of the hub in an LTO cartridge. The reel’s
`
`engagement gear, which itself is inset with respect to the inner surface of the hub,
`
`has an outer diameter “D” that is described and claimed to be larger than the outer
`
`diameter “d” of the braking gear. Ex. 1001 at 6:17-20, claim 3. A fortiori, the inner
`
`diameter of the hub (which is larger than the outer diameter of the reel’s engagement
`
`gear) is larger than the outer diameter of the braking gear, resulting in clearance
`
`between the braking gear and the inner surface of the hub.
`
`
`
`- 9 -
`
`

`

`
`
`
`
`18.
`
`Indeed, the ’905 patent is based on the idea that clearance between the
`
`braking member and other components with respect to which it moves can cause the
`
`braking member in an LTO cartridge to move “off center” (id., 1:67), requiring guide
`
`members to center it again. Mr. Vanderheyden proceeds from an assumption – i.e.,
`
`
`
`- 10 -
`
`

`

`that LTO-style braking members lack clearance relative to the reel hub and thus
`
`cannot go off-center – that directly contradicts the key premise of the ’905 patent
`
`itself.
`
`19. Mr. Vanderheyden also contends, as a backup argument, that “[e]ven if
`
`some spacing alleged by the Petitioner was present…that in itself does not mean
`
`there would be misalignment. The specific amount of spacing is critical to
`
`understanding whether misalignment issues would exist.” Ex. 2008, ¶136. Here Mr.
`
`Vanderheyden misses the point of my obviousness analysis. While it is physically
`
`possible with sufficient time and resources and precise enough manufacturing
`
`equipment, to build a tape cartridge in which clearances are small enough to
`
`minimize misalignment of a braking member, doing so is an expensive and time-
`
`consuming proposition. Laverriere clearly taught – a decade before the teaching was
`
`reiterated in the ’905 patent itself – that adding guide members was an efficient way
`
`to address the possibility of misalignment due to clearances that could and likely
`
`would exist in practical implementations of a tape cartridge that includes a braking
`
`member that moves up and down to unlock and lock a reel. The fact that it is possible
`
`to make a tape cartridge that can operate with little clearance (and thus without a
`
`need for guide members) does not disturb the conclusion that, in view of Laverriere’s
`
`clear teachings, guide members are obvious components to use to address
`
`
`
`- 11 -
`
`

`

`misalignment, instead of expending the resources necessary to avoid the need to use
`
`guide members.
`
`2.
`
`A POSA Knew There Must Be Clearance Between
`McAllister-I’s Mating Components
`20. Mr. Vanderheyden also says, repeatedly, that LTO cartridges were
`
`designed by the LTO consortium with a “tight fit” between the mating components
`
`(which he refers to as “male” and “female” components) that connect the top of the
`
`braking member to the shell of the cartridge, such that misalignment of the braking
`
`member would not occur. Ex. 2008 ¶¶69, 71, 74, 131, 139. Once again, Mr.
`
`Vanderheyden’s premise contradicts the ’905 patent itself, which includes Figure 5
`
`showing clearance between the mating components in question, in a “prior art” LTO
`
`cartridge, such that the braking member tilts substantially.
`
`21. Mr. Vanderheyden cites a single sentence from McAllister-I in support
`
`of this assertion that the LTO consortium (and McAllister-I) anticipated a “tight fit”
`
`between the mating components, without clearance that would permit misalignment:
`
`“Locking gear is moveable in only one dimension, parallel to the axis of rotation of
`
`reel 14.” Ex. 1005 at 3:44-45. Mr. Vanderheyden misinterprets this sentence, which
`
`simply conveys that the braking member was designed to move up and down parallel
`
`to the axis of rotation (i.e., to unlock and lock the reel) but not to rotate. To stop the
`
`reel from rotating, of course, the braking member itself must be locked against
`
`rotation. This is how the LTO consortium, of which my employer HP was a member,
`- 12 -
`
`
`
`

`

`and in which I personally participated in the original design of the LTO cartridge,
`
`understood the function of the braking member.
`
`22. Other LTO prior art confirms this straightforward understanding of the
`
`mating components. Morita-II ¶29 (“…whereby the brake member 104 is able to
`
`move toward and away from the bottom wall 121a of the reel hub 121 without
`
`rotating relative to the reel hub”); Mizutani ¶19 (“…vertical sliding is enabled, but
`
`relative rotation is disabled…”); Tsuyuki ¶16 (describing components as
`
`“restrict[ing]” the brake “to a non-rotatable state”).
`
`23. Given that the braking member must move up and down to unlock and
`
`lock the reel, the “tight fit,” with zero clearance, that Mr. Vanderheyden argues
`
`existed between the mating components in LTO cartridges (and in McAllister-I in
`
`particular), would render the cartridge unusable because the braking member would
`
`be unable to move reliably and repeatably between the locked (“in hand”) and
`
`unlocked (“in drive”) configurations. In a mechanical device requiring repeated
`
`movement of connecting parts relative to one another, such friction would be
`
`intolerable. No POSA would interpret McAllister-I to describe the zero-clearance
`
`arrangement that Mr. Vanderheyden suggests.
`
`24. Moreover, contrary to Mr. Vanderheyden’s assumption, the LTO
`
`consortium absolutely recognized that the mating components that connect the
`
`braking member to the cartridge shell would have clearances, and even specified the
`
`
`
`- 13 -
`
`

`

`maximum effect of those clearances. For example, in ECMA-319 (Ex. 1034)—the
`
`published standard for the first generation of LTO cartridges—Section 8.6.1 requires
`
`that, in the locked position, “the angular resolution [of the locking mechanism] shall
`
`not be greater than 3°,” and that the reel, which in the locked position is coupled to
`
`the braking member, “shall not rotate by more than 10° when a torque not greater
`
`than 0,32 N· m is applied in the direction that will cause the tape to unwind.”
`
`25. Likewise, Section 8.6.7 required that, in the in-hand position (i.e., when
`
`the reel is locked against rotation) “[t]he d16 dimension of the reel” (i.e. its central
`
`axis) “shall be centered to the central window (figure 3) within ±0.25 mm.”
`
`26. Clearances between the mating components connecting the braking
`
`member to the cartridge shell contribute both to the permitted rotation of the reel
`
`(8.6.1) and to its permitted displacement relative to center (8.6.7). Thus, the LTO
`
`consortium expressly acknowledged, in the LTO standard itself, that these mating
`
`components would have clearances between them, permitting some rotation and
`
`displacement of the braking member and the reel (coupled to the braking member).
`
`Simply put, the LTO consortium recognized the mechanical engineering reality that
`
`assembly clearances, as well as variations in part dimensions (i.e., manufacturing
`
`tolerances) were a necessary part of any mechanical design.
`
`27. Given the requirement for operational clearance between moving
`
`components, a POSA would have recognized that there was some space between
`
`
`
`- 14 -
`
`

`

`female structure 60 on locking gear 42 and male structure 58 on cartridge housing
`
`12. Such space would have introduced the potential for locking gear 42 to become
`
`misaligned or tilted. The prior art confirms this.
`
`28. Mizutani, for example, explains that for the mating projections to allow
`
`vertical movement “there must be a certain amount of clearance maintained between
`
`the” projections. Mizutani ¶5. This clearance, Mizutani explains, is a “factor”
`
`causing the brake “to tilt.” Id.
`
`29. Shima, which Mr. Vanderheyden cites, also confirms that clearance
`
`between mating projections creates the potential for the brake to become misaligned.
`
`Shima explains that “looseness of engagement between the upper casing and brake
`
`lock or between brake lock and hub can sometimes bring the center of brake lock 5
`
`out of alignment.” Ex. 2002 at 5:47-50. Shima thus recognizes the potential for
`
`“looseness,” i.e., clearance, between the mating projections in an LTO cartridge to
`
`create brake misalignment.
`
`30. Tsuyuki, which discloses an LTO cartridge, also recognizes that even
`
`with mating projections “[i]t is difficult to hold [the brake] matched to the reel
`
`rotation center.” Tsuyuki ¶6. A POSA would understand that clearance is the cause
`
`of the difficulty.
`
`
`
`- 15 -
`
`

`

`The Location of McAllister-I’s Spring Is Irrelevant
`3.
`31. Mr. Vanderheyden states that the “position of biasing spring 64 in
`
`McAllister-I also helps to prevent any potential misalignment of locking gear 42.”
`
`Ex. 2008, ¶141. Again, I disagree.
`
`32. McAllister-I is explicit that the location of its biasing spring is
`
`exemplary and that “any suitable interlocking structures and biasing mechanism may
`
`be used.” McAllister-I at 3:61-64. If, as Mr. Vanderheyden posits, the position of
`
`the spring served an important function such as preventing potential misalignment,
`
`McAllister-I certainly did not recognize it.
`
`33.
`
`Indeed, a centrally located spring is more likely to cause misalignment
`
`of the locking gear than to prevent it. With a centrally located spring, the urging
`
`force on the locking gear is focused on the center of the locking gear. Any
`
`counterforces on the outer perimeter of the locking gear would be largely unopposed
`
`and the central spring would act as a fulcrum aiding, rather than preventing, tilting.
`
`In contrast, a large diameter spring located around the perimeter of the locking gear
`
`would oppose any counterforces and decreases the amount of tilt the locking gear
`
`experiences. I illustrate this phenomenon below:
`
`
`
`- 16 -
`
`

`

`Central Spring Design
`
`Peripheral Spring Design
`
`
`Locking Gear
`
`
`
`34. McAllister-I’s spring, if relevant to the presence of tilt at all, suggests
`
`
`
`
`
`that McAllister-I is even more prone to tilt than other LTO-type cartridges that use
`
`a peripheral spring design.
`
`B.
`
`The Proposed Combination Would Operate as Intended and
`Would Not Require Significant Redesign
`The Proposed Combination Would Operate as Intended
`1.
`35. Mr. Vanderheyden argues that adding the centering ribs of Laverriere
`
`to the inner surface of the McAllister-I reel hub would inhibit the function of the
`
`McAllister-I cartridge and/or require significant redesign. I disagree.
`
`36. Mr. Vanderheyden notes Laverriere’s description that its centering ribs
`
`“contain[] the brake button and maintain[] the brake button in the desired position.”
`
`Ex. 2008, ¶156. Mr. Vanderheyden then interprets this to mean that there can be no
`
`
`
`- 17 -
`
`

`

`clearance between the centering ribs and the braking member (particular once the
`
`braking member is adjacent the narrowest “vertical” portion of the ribs as the braking
`
`member enters the locked position) and that this lack of clearance would inhibit the
`
`function of the cartridge. Ex. 2008, ¶157. A POSA, however, would understand
`
`that the quoted phrase merely means directing the brake toward the center of the reel
`
`but would not remove all clearance. The brake needs to move up and down, and a
`
`POSA would have included clearance between the vertical portions of the ribs and
`
`the braking member so that the braking member could transition smoothly from the
`
`locked position to an unlocked position.
`
`37.
`
`In fact, Laverriere is clear that incorporating guide ribs requires
`
`“minimal modifications to the structure of the hub 66” and the presence of the ribs
`
`“does not otherwise interfere with assembly or operation of the cartridge.” Ex. 1007
`
`at 5:25-27. A POSA would recognize that to avoid interfering with the operation of
`
`the cartridge, some clearance is required.
`
`38. Mr. Vanderheyden’s opinion is based on a misreading of Laverriere.
`
`Mr. Vanderheyden interprets Laverriere’s use of the word “abut” to mean that there
`
`is contact between “a vertical surface of the disc 61” of the braking member and a
`
`“corresponding vertical surface on projecting means 70.” Ex. 2008, ¶ 105; see also
`
`id. ¶¶ 146, 156. In support of his interpretation, Mr. Vanderheyden cites Column 5,
`

`39. Yet, Laverriere is clear that the “abutting surface” is the inclined
`
`portion 72 (red below)—not the vertical portion (green below) of the projecting
`
`means 70 (yellow below). “The projecting means 70 preferably includes an
`
`abutting surface 72 which is angled relative to a plane tangential to the annular
`
`wall 68 of the hub 66.” Ex. 1007 at 4:30-31.5 The so-called “vertical portion” of
`
`the projecting means is not “angled relative to a plane tangential to the annular wall
`
`68.” Rather, it is a cylinder that is parallel to the cylinder of the annular wall 68 of
`
`the hub 66.
`
`
`5 Elsewhere Laverriere mentions that curves 76 and 77 (which likewise are angled
`
`relative to a plane tangential to the annular wall 68 of the hub 66) “cause the abutting
`
`surface 72…to include angled, contoured steps which gradually and positively
`
`receive and position the circular brake concentrically relative to the hub 66.” Ex.
`
`1007 at 4:46-53. Thus, curves 76 and 77, as well as inclined abutting surface 72, are
`
`also abutting surfaces that contact and center the braking member. But the “vertical”
`
`portions of the projections 70’ (i.e., the cylindrical portions like the portion colored
`
`green above) are not angled or contoured and are not described as centering the
`
`braking member – in fact, because they are vertical they cannot move the braking
`
`member toward center.

`

`
`40. Likewise, claim 1 of Laverriere refers to the “surface 72 of the
`
`projecting means as that which “abuts the circular periphery of the brake button…”
`
`Ex. 1007 at 5:49-51. This recitation, which is one of the passages on which Mr.
`
`Vanderheyden relies, establishes the opposite of what he suggests: it is the inclined
`
`surface (conical section in red above), not the vertical surface (cylindrical section in
`
`green above) of the rib that contacts the braking member.
`
`41. Mr. Vanderheyden also cites Column 4, line 55 through Column 5, line
`
`2 of Laverriere. That portion merely says that the “projecting means 70” as a whole
`
`receives and centers the braking member. It also states that the “first step 78 formed
`
`on the bottom portion 69 of the hub 66 advantageously receives the first step 80
`
`formed on the brake button 61”s—referring to two horizontal (not vertical) surfaces
`
`in the view of Figure 3. The word “receives” in no way implies a lack of clearance
`
`between the vertical cylindrical portions of the braking member and the projecting
`
`means. Indeed, there is nothing in Laverriere suggesting that the vertical
`
`(cylindrical) portion of the projecting means contacts, let alone constrains, the
`
`braking button in the Laverriere arrangement. In fact, the evidence is 100% to the
`- 20 -
`
`
`
`

`

`contrary: Laverriere states very clearly that the rib “does not otherwise interfere with
`
`assembly or operation of the cartridge.” Ex. 1007 at 5:25-27.
`
`42. Mr. Vanderheyden also cites Shima when arguing that “a POSA would
`
`not look to combine the [centering ribs] of Laverriere with an LTO-type cartridge
`
`described in McAllister-I.” 2008 ¶158. The portion of Shima that Mr.
`
`Vanderheyden cites explains that “smooth release of the brake” in the Laverriere
`
`design “is sometimes impossible because…the outer periphery of [the braking
`
`member] catches a sloped rib” due to misalignment of the brake. Ex. 2002 at 1:60-
`
`67. This passage merely identifies a potential problem with guide ribs during
`
`“release.” i.e., transition from the locked to unlocked state. To resolve this potential
`
`problem, Shima teaches the use of a release member—like spider washer 40 used in
`
`McAllister-I—with a dented center that keeps the brake centered during the
`
`transition from the locked to unlocked states. Ex. 2002 at 2:1-5, 5:46-6:4
`
`43. As noted in the prior paragraph, Shima is focused on centering the brake
`
`during the transition from the locked to unlocked state, and it offers a solution for
`
`keeping the braking member centered during that process to avoid the potential
`
`problem of the braking member catching on a rib. Shima never suggests that the
`
`ribs – which help center the braking member during the transition from the unlocked
`
`state to the locked state – should be removed. As Laverriere explains, and Shima
`
`does not dispute, the centering ribs “gradually and positively receive and position
`
`
`
`- 21 -
`
`

`

`the circular brake button concentrically relative to the hub.” Laverriere at 4:51-53.
`
`The ribs “receive” and “position” the brake when the brake is moving down to
`
`transition the cartridge from the unlocked state to the locked state. Thus, the
`
`centering ribs perform the centering function during the locking process and Shima’s
`
`dented spider washer does so during the unlocking process. In short, nothing in
`
`Shima would have discouraged a POSA from using Laverriere’s centering ribs in an
`
`LTO cartridge such as McAllister-I.
`
`2.
`
`The Proposed Combination Would Not Require Significant
`Redesign
`44. Mr. Vanderheyden also argues that the proposed combination would
`
`“require engineering redesigns to several existing components” of the McAllister-I
`
`cartridge. 2008 ¶163. I disagree that the proposed combination would require more
`
`than ordinary, indeed very modest, effort.
`
`45. Mr. Vanderheyden speculates that the diameters of the reel hub 32,
`
`locking gear 42 and reel gear 34 would need to be modified to accommodate the
`
`Laverriere centering ribs. Ex. 2008 ¶163. I disagree. As Mr. Vanderheyden has
`
`noted, McAllister-I does not specify precise dimensions in either its text or drawings.
`
`It depicts the necessary and expected clearance a POSA would know was required
`
`for a functional mechanism. The design and dimensioning of centering ribs within
`
`the existing constraints would be straightforward work for a mechanical engineer
`
`with two years of experience in cartridge design or equivalent work
`- 22 -
`
`
`
`

`

`46. Mr. Vanderheyden also speculates that “spider washer 40 and legs 50
`
`would need to be reshaped, and interlocking structures 58 and 60 would need to be
`
`adjusted and maybe even reshaped.” Ex. 2008, ¶163. Again, I disagree. I do not
`
`know what specific design changes Mr. Vanderheyden envisions, but the proposed
`
`combination could have been accomplished without any need to alter spider washer
`
`40, its legs 50, or the interlocking structures 58 and 60. To the extent some
`
`modifications would have been needed for some unknown reason, a mechanical
`
`engineer with two years of experience in cartridge design would certainly know how
`
`to accomplish such modifications.
`
`II. GROUND 2: MCALLISTER ANTICIPATES CLAIM 3
`I agree with Mr. Vanderheyden that the standard dictionary definition
`47.
`
`of diameter is “a straight line segment passing through the center of a figure, esp. a
`
`circle or sphere, and terminating at the periphery.” Ex. 2008, ¶169. I disagree,
`
`however, with his suggestion that a POSA cannot assess a figure’s implied diameter
`
`simply because a straight line segment cannot be drawn on the figure.
`
`48. POSAs—mechanical engineers with two years of cartridge design
`
`experience in addition to years of mechanical engineering education—would have
`
`been able to assess a component’s implied diameter even if a drawing of the
`
`component was presented such that a straight segment could not be accurately drawn
`
`on it. This is especially true where, as here, the issue is whether the diameter of one
`
`
`
`- 23 -
`
`

`

`component is any amount larger than the diameter of another component. The
