`
`I.
`
`Introduction
`
`
`
`Apple’s constructions are at odds with the intrinsic and extrinsic evidence and
`
`should be rejected.1 Apple repeatedly violates the cardinal rule of claim construction
`
`1
`
`2
`
`3
`
`4
`
`by indiscriminately seeking to write new limitations into the claims. For example,
`
`5
`
`Apple contends “wherein the ferrofluid reduces at least a mechanical resonance”
`
`6
`
`mandates a substantially uniform, non-peaked response when nothing in the claim
`
`7
`
`suggests that, and no evidence shows the required clear and unmistakable disclaimer
`
`8
`
`of scope Apple contends was made. No reason exists why the jury could not apply this
`
`9
`
`phrase, and other terms in dispute, as written without the surplus language Apple seeks
`
`10
`
`to inject. Apple’s contention that certain claim phrases are indefinite also lacks merit.
`
`11
`
`In contrast, Taction’s constructions flow directly from the intrinsic record and should
`
`12
`
`be adopted.

`
`A.
`“wherein the ferrofluid reduces at least a mechanical resonance
`within the frequency range of 40-200 Hz” / “wherein the viscous
`ferrofluid reduces at least a resonance within a frequency range of 40-200
`Hz” / “wherein the ferrofluid damps at least a resonance”
`
`Claims
`
`Taction’s
`Construction
`
`Apple’s Construction
`
`’885 patent, cls. 1, 17
`’117 patent, cls. 1, 9, 16
`
`Plain and ordinary
`meaning
`
`“wherein the ferrofluid produces
`a substantially uniform, non-
`peaked response over the
`frequency range of 40-200 Hz”
`
`Apple improperly rewrites a claim phrase that is clear on its face and can easily
`
`be applied by the jury as written. This phrase merely requires a mechanical resonance
`
`
`
`1 By abandoning its constructions for “plurality of flexures that are generally flat
`and generally rectangular” and “plurality of protrusions that He within a same plane
`as adjacent portions of the plurality of flexures,” after telling the Court it would brief
`them (Dkt. 58 (Joint Hearing Statement) at 2-5; Dkt. 58-1 (Joint Claim Construction
`Chart) at 25-29), Apple caused Taction to waste two pages in its opening brief
`unnecessarily addressing those terms. Dkt. 73 (“Taction Br.”) at 23-25.

`TACTION’S RESPONSIVE CLAIM CONSTRUCTION BRIEF
`
`
`
`

`

`
`
`
`1
`
`to be reduced, just as the patent describes and the prosecution history and extrinsic
`
`2
`
`evidence support. Nothing warrants Apple’s reading in of a limitation requiring a
`
`3
`
`substantially uniform, non-peaked response over the claimed frequency range.
`
`4
`
`Tellingly, Apple itself continued to rely on Taction’s plain meaning construction at the
`
`5
`
`PTAB (to seek invalidity) even after filing its opening Markman brief and even after
`
`6
`
`the PTAB denied institution of all four of Apple’s IPR petitions. See, e.g., Ex. 1,2
`
`7
`
`IPR2022-00057, Petition for Rehearing at 3 n.1 (“This proceeding captures
`
`8
`
`independent claims 1 and 17, both of which include nearly identical language requiring
`
`9
`
`a reduction in resonance within the frequency range of 40-200 Hz.”);3 see also id. at
`
`10
`
`1 (“Ground 1 relied upon Kajiwara, which disclosed a reduction of the resonance
`
`11
`
`amplitude at ~150 Hz. Ground 2 relied upon Park728, which disclosed a reduction of
`
`12
`
`resonance amplitude from 80-180 Hz.”).4 Applying plain and ordinary meaning here
`
`13
`
`would not “invite[] legal error” or otherwise “leav[e] the question of claim scope
`
`14
`
`unanswered” since the plain meaning is indisputable: reduce means “reduce,” not
`
`15
`
`“eliminate” or “completely flatten.”5 Cf. Eon Corp. v. Silver Spring Networks, Inc.,
`
`16
`
`815 F.3d 1314, 1319 (Fed. Cir. 2016).
`
`17
`
`Apple commits the “cardinal sin” of importing limitations from embodiments
`
`18
`
`into the claim language. SciMed Life Sys. Inc. v. Advanced Cardiovascular Sys. Inc.,
`
`19
`
`242 F.3d 1337, 1340 (Fed. Cir. 2001); Pelican Int’l Inc. v. Hobie Cat Co., No. 20-CV-

`
`
`2 All exhibits are attached to the Declaration of Gavin Snyder filed herewith.
`
`3 All emphases are added unless otherwise noted.
`
`4 All of Apple’s petitions for rehearing were also denied by the PTAB.
`
`5 Apple also erroneously argues that claim 1 of the ’885 patent is representative
`and therefore claim 16 of the ’117 patent should be interpreted to include a 40-200
`Hz frequency limitation, which it does not have. Dkt. 72 at 8. Construing claim 16
`of the ’117 patent to have the same scope as the other claims is particularly
`inappropriate. InterDigital Commc’ns, LLC v. Int'l Trade Comm’n, 690 F.3d 1318,
`1324 (Fed. Cir. 2012) (the doctrine of claim differentiation prevents limitations from
`one claim being read into another claim that has different language).

`
`
`
`1
`
`2390-BAS-MSB, 2022 WL 298959, at *16 (S.D. Cal. Feb. 1, 2022) (stating the
`
`2
`
`“bedrock principle of patent law” that “particular embodiments appearing in a
`
`3
`
`specification will not be read into the claims when the claim language is broader than
`
`4
`
`such embodiments”). Apple does not dispute that “substantially uniform” and “non-
`
`5
`
`peaked” are not in the claims, and run directly contrary to the “reduce” language the
`
`6
`
`PTO approved. Compounding Apple’s error, none of the embodiments it relies on
`
`7
`
`(Dkt. 72 (“Apple Br.”) at 9-10, 11 (citing ’885 patent at Abstract, 2:25-36, 3:53-58,
`
`8
`
`5:49-52, 9:36-44)) contain all the limitations it seeks to read in. Optis Wireless Tech.,
`
`9
`
`LLC v. Huawei Device Co., No. 2:17-CV-123-JRG-RSP, 2018 WL 476054, at *22-23
`
`10
`
`(E.D. Tex. Jan. 18, 2018) (rejecting proposed construction that “mixes features of
`
`11
`
`various embodiments”). And Poly-America, L.P. v. API Industries, Inc. is
`
`12
`
`distinguishable as the court found “[e]very embodiment described in the specification
`
`13
`
`has [the proposed limitation] and every section of the specification indicates the
`
`14
`
`importance of [the proposed limitation].” 839 F.3d 1131, 1137 (Fed. Cir. 2016).
`
`15
`
`Although Apple contends Taction disavowed the claim scope by disparaging
`
`16
`
`prior art, “disavowal of claim scope through disparagement of the prior art in the
`
`17
`
`specification” is a “high bar” and criticizing prior art does itself not automatically rise
`
`18
`
`to clear disavowal. See, e.g., Openwave Sys., Inc. v. Apple Inc., 808 F.3d 509, 517
`
`19
`
`(Fed. Cir. 2015); Cont’l Cirs. LLC v. Intel Corp., 915 F.3d 788, 798 (Fed. Cir. 2019);
`
`20
`
`Kingspan Insulated Panels Inc. v. Centria GP, No. 1:15-CV-1023, 2018 WL 1256559,
`
`21
`
`at *7 (W.D. Mich. Mar. 12, 2018) (finding prior art criticisms insufficient to disavow
`
`22
`
`claim scope “in light of the lack of support in the claim language for [the] proposed
`
`23
`
`construction”). Further, the discussion of prior art in the specification Apple cites
`
`24
`
`(Apple Br. at 9-10) describes prior art transducers without added damping, not damped
`
`25
`
`transducers, and does not mention “reduction” of resonance at all. ’885 patent at 2:1-
`
`26
`
`10 (noting the “lack of mechanical damping” in prior art); 2:10-36 (mentioning “un-
`
`27
`
`damped linear resonant actuators”).

`
`
`
`1
`
`parent application, Apple Br. at 10-11, also lacks merit as the claim language in that
`
`2
`
`application6 and the phrase here are different. See, e.g., Invitrogen Corp. v. Clontech
`
`3
`
`Labs., Inc., 429 F.3d 1052, 1078 (Fed. Cir. 2005) (“[T]he prosecution of one claim
`
`4
`
`term in a parent application will generally not limit different claim language in a
`
`5
`
`continuation application.”); ResQNet.com, Inc. v. Lansa, Inc., 346 F.3d 1374, 1383
`
`6
`
`(Fed. Cir. 2003) (“Although a parent patent's prosecution history may inform the claim
`
`7
`
`construction of its descendant, the [parent] patent's prosecution history is irrelevant to
`
`8
`
`the meaning of this limitation because the two patents do not share the same claim
`
`9
`
`language.”). And the language Apple points to regarding “highly resonant” prior art
`
`10
`
`actuators being different from Taction’s “highly damped output” fully supports
`
`11
`
`Taction’s construction. Apple Br. at 10-11. Taction never contended that a reduction
`
`12
`
`of mechanical resonance was not encompassed by the claims or invention.
`
`13
`
`Nor does the extrinsic Taction marketing material Apple relies on include the
`
`14
`
`limitations Apple proposes. Apple Br. at 11-12. For example, the white paper states
`
`15
`
`that “for purposes of our tactile transducer, you can think of damping as a method for
`
`16
`
`. . . reducing resonances.” Dkt. 72-3 at 18. Further, the terms “flatter” and “flattest”
`
`17
`
`that Apple heavily relies on (Dkt. 72-4 at 2; Dkt. 72-3 at 6) are relative terms that are
`
`18
`
`not in the claim language or specification, and in no way suggest that only
`
`19
`
`“substantially uniform, non-peaked” responses are permitted.
`
`20
`
`21

`22
`
`23

`
`28
`
`B.
`“wherein the ferrofluid reduces the Q-Factor of the response of the
`apparatus over at least a portion of the frequency range of 40-200 Hz” /
`“wherein the ferrofluid reduces a Q-factor of a response of the apparatus
`over at least a portion of a frequency range of 40-200 Hz”
`
`
`
`6 “[W]herein the motion of the moveable member is damped to reduce the Q-
`factor of the vibration module over the frequency range of 40-200 Hz.” Dkt 72-5 at
`76 (amended claim 15). What’s more, a different, dependent claim specified “wherein
`the damping member flattens the acceleration response of the module to a Q-factor of
`less than 1.5, over the frequency range of 40-200 Hz.” Id. at 72-73 (original language
`in claim 2). This demonstrates that when Taction intended to claim a “flattened”
`response, it knew how to do so, and claims that are directed to a reduced resonance
`should not be construed to flatten a response.

`“wherein the ferrofluid produces a
`substantially uniform, non-peaked response
`over the frequency range of 40-200 Hz”
`
`Apple contends that only a device, rather than a haptic response of a device, can
`
`have a Q-factor. Apple Br. at 14. But a POSITA would have no trouble understanding
`
`with “reasonable certainty” the claims as written, because a device’s haptic properties
`
`necessarily apply to haptic effects played on the device. Thus, it makes perfect sense
`
`for the claims to refer to the Q-factor of a “response of the apparatus.” Taction Br. at
`
`13; Dkt. 73-2 (“Oliver Decl.”) ¶¶ 50-58; see also Cox Commc’ns, Inc. v. Sprint
`
`Commc’n Co. LP, 838 F.3d 1224, 1231-32 (Fed. Cir. 2016) (“As Nautilus instructs,
`
`the dispositive question in an indefiniteness inquiry is whether the ‘claims,’ not
`
`particular claim terms, ‘read in light of the specification delineating the patent, and the
`
`prosecution history, fail to inform, with reasonable certainty, those skilled in the art
`
`about the scope of the invention.’”) (citation omitted). Additionally, the patent
`
`examiner—a POSITA—readily understood the scope of the invention in the ’885
`
`patent application. Dkt. 73-7 at 9 (applying “reducing the Q factor over at least a
`
`portion of the frequency range of 40-200Hz” to prior art); see also Taction Br. at 11.
`
`Nothing in Apple’s brief suggests that there is any evidence, much less clear and
`
`convincing evidence, that the term is indefinite. Other than Apple’s assertion that the
`
`phrase is “nonsensical” (Apple Br. at 14), Apple does not identify any perceived
`
`ambiguity that prevents a POSITA from being informed by the claim of the scope of
`
`the invention with reasonable certainty. Conspicuously, Apple fails to address the
`
`intrinsic and extrinsic evidence that Taction relies on in its brief to show why the phrase
`
`is not indefinite. Id. at 11-12. And even if the drafting of the claim language were
`
`“imperfect” or “somewhat problematic” (it is not), “the court should resolve any
`
`ambiguity in favor of the patentee.” Energizer Holdings, Inc. v. Int’l Trade Comm’n,

`
`2
`
`435 F.3d 1366, 1370 (Fed. Cir. 2006). Thus, the phrase is not indefinite.7
`
`Apple’s alternative construction fares no better.8 Apple relied upon Taction’s
`
`3
`
`plain meaning construction of “over at least a portion” in its IPR petitions when it was
`
`4
`
`beneficial to Apple, but now seeks a narrower construction in litigation. See, e.g., Ex.
`
`5
`
`2, IPR2022-00059 Petition at 47-48 (claiming that Miyazaki-Park494-Kajiwara
`
`6
`
`combination met this limitation “because the operating frequency is between at least
`
`7
`
`120-180Hz, which is within the range of 40-200Hz”) (emphasis added; see also id. at
`
`8
`
`61 (similar discussion for the 80-180Hz range in the Park728 reference). Apple also
`
`9
`
`conflates Q-factor with resonance, but they are distinct terms that describe overlapping
`
`10
`
`but different subject matter. Apple Br. at 15. Resonance is merely a numerator in the
`
`11
`
`Q-factor (with the resonance width being the denominator). Taction Br. at 11; Oliver
`
`12
`
`Decl. ¶ 51. While reducing the resonance will reduce the Q-factor, reducing the Q-
`
`13
`
`factor does not necessarily mean reducing the resonance. Apple’s alternative
`
`14
`
`construction should be denied for reading “Q-factor” out of the claims.

`
`
`“material that produces a
`dipolar magnetic field”
`
`No construction required as the
`plain meaning controls.
`To the extent that a construction is
`required, “a ferromagnetic body
`that produces a magnetic field”
`
`Apple’s chief argument for reading “ferromagnetic” into this term is that non-
`
`ferromagnetic magnets are purportedly not strong enough to move the mass in haptic
`
`actuators. Apple Br. at 16. But this supports Taction’s position, not Apple’s. Since
`
`
`
`7 Although indefiniteness is not a basis for finding invalidity in an IPR, Apple
`had no difficulty in applying the plain meaning of the phrase under the Phillips
`standard. See, e.g., Ex. 2, IPR2022-00059 Petition at 6, 40-50, 53-61.
`
`8 Apple does not address Taction’s argument that Apple is seeking to improperly
`replace “over at least a portion” with “over.” Taction Br. at 13.

`TACTION’S RESPONSIVE CLAIM CONSTRUCTION BRIEF

`
`

`

`Case 3:21-cv-00812-TWR-JLB Document 111 Filed 07/21/22 PageID.3588 Page 11 of 15
`
`
`
`1
`
`the surrounding context of the asserted claims already requires that the magnets are
`
`2
`
`strong enough to move the mass, there is no need to add a “ferromagnetic” restriction
`
`3
`
`to this term in order to indirectly limit the magnets to a particular type of stronger
`
`4
`
`magnets. There are other types of magnetic material, as admitted by Dr. Hayward and
`
`5
`
`explained further by Dr. Henriksen. Dkt. 72-2 (Hayward Decl.) ¶ 90; Dkt. 73-4
`
`6
`
`(“Henriksen Decl.”) ¶¶ 41-42. If such materials are powerful enough to move the mass
`
`7
`
`and work in a device that otherwise practices the claims, they should not be arbitrarily
`
`8
`
`excluded from the claims. Apple also alleges that “the specification . . . does not
`
`9
`
`disclose any embodiment wherein the claimed magnets lose their magnetic properties
`
`10
`
`once an external field is removed,” Apple Br. at 16, but there is similarly no statement
`
`11
`
`excluding any such magnets. And, as Dr. Henriksen notes, ferrimagnetic and
`
`12
`
`antiferromagnetic magnets are also permanent magnets, like ferromagnets (but would
`
`13
`
`be excluded by Apple’s construction). Henriksen Decl. ¶ 41.
`
`14
`
`Apple also incorrectly asserts the term “dipolar” only makes sense applies to
`
`15
`
`magnets, not fields. But this is simply wrong. As Dr. Henriksen explained, it is
`
`16
`
`common to refer to magnetic fields produced by dipolar magnets as dipolar magnetic
`
`17
`
`fields. Henriksen Decl. ¶ 35. Apple also does not address the specification’s
`
`18
`
`description of the polarization of the magnets, which shows they produce a dipolar
`
`19
`
`magnetic field. E.g., ’885 patent at 3:5-6; 4:39-30; 7:32-33; 8:16-17.
`
`20
`
`Last, Apple offers no justification for its proposed restriction to a “body” rather
`
`21
`
`than a “material.” Taction’s construction of “magnet” thus better aligns with the
`
`22
`
`intrinsic evidence, as well as the relevant science of magnets.

`
`
`
`This claim language is clear on its face and can easily be applied by the jury.
`
`Moreover, contrary to Apple’s argument, the Dow and Teva cases have no applicability
`
`here. In Dow, the court found “neither the patent claims nor the specification . . .
`
`provide[d] any guidance as to which method should be used.” Dow Chem. Co. v.
`
`NOVA Chem. Corp., 803 F.3d 620, 633 (Fed. Cir. 2015). Similarly, in Teva, the court
`
`found that the specification provided no guidance on which measurement method to
`
`use, and the term did “not have a plain meaning to one of skill in the art.” Teva Pharm.
`
`USA, Inc. v. Sandoz, Inc., 789 F.3d 1335, 1344-45 (Fed. Cir. 2015) (“The specification
`
`never . . . even mentions [the different measurement methods].”). Later Federal Circuit
`
`cases confirm that “if a skilled person would choose an established method of
`
`measurement, that may be sufficient to defeat a claim of indefiniteness, even if that
`
`method is not set forth in haec verba in the patent itself.” Presidio Components, Inc.
`
`v. Am. Tech. Ceramics Corp., 875 F.3d 1369, 1376-77 (Fed. Cir. 2017). In Presidio,
`
`although multiple measurement methods existed, “the general approach was
`
`sufficiently well established in the art and referenced in the patent to render the claims
`
`not indefinite.” Id. at 1377. Here, the measurement scheme is well established for a
`
`POSITA. Oliver Decl. ¶¶ 60-64; Presidio at 1377. It is also supported by the
`
`specification.9 Taction Br. at 19-21. Thus, the term is definite. See Sonix Tech. Co.
`
`
`
`9 Even if this Court were to find that no guidance is provided in the intrinsic
`evidence, and it should not, “whether a POSA would find there are competing existing
`methodologies on how to conduct the [measurement] is a disputed factual issue,” and
`inappropriate to resolve at claim construction. First Quality Tissue, LLC v. Irving
`Consumer Prod. Ltd., No. CV 19-428-RGA, 2022 WL 958089, at *4 (D. Del. Mar.
`30, 2022); see also Celgard, LLC, v. Shenzhen Senior Tech., No. CV. 19-05784-JST,
`at *15-16 (N. D. Cal. Aug. 6, 2021) (Ex. 3) (this fact issue cannot be resolved at claim
`construction).

`

`
`Indefinite
`
`’117 patent, cls. 1, 9
`
`Plain and ordinary meaning
`
`
`
`Apple lists examples where terms of approximation can be indefinite. But these
`
`examples analyze the terms “large” and “minimal,” which are terms reflecting relative
`
`sizes, which require a point of comparison. Apple Br. at 21. In contrast, “generally”
`
`has been held in a multitude of controlling cases to be definite. Taction Br. at 20-21
`
`(citing four Federal Circuit cases finding “generally” to be definite).
`
`Apple also applies a specific dictionary definition of “cuboid”: “a solid square
`
`object with six equal sides.”10 However, Apple’s own dictionaries provide another
`
`equally viable definition of cuboid that Apple completely ignores. See e.g., Dkt. 72-6
`
`at 90 (defining cuboid: “a six-sided figure each face of which is a rectangle”); Dkt. 72-
`
`7 at 93 (similar); Dkt. 72-8 at 96 (similar); Dkt. 72-9 at 99 (similar).
`
`Markedly, and as Apple agrees, there are no examples in the intrinsic evidence
`
`that fit Apple’s proposed construction of “shaped like a cube”—plainly because this
`
`construction is at odds with all disclosed embodiments. On-Line Techs., Inc. v.
`
`Bodenseewerk Perkin-Elmer GmbH, 386 F.3d 1133, 1138 (Fed. Cir. 2004) (“[A] claim
`
`interpretation that excludes a preferred embodiment from the scope of the claim is
`
`rarely, if ever, correct.”). Instead, the patents depict a “six sided figure in which each
`
`face is a rectangle,”11 including in Figure 4:
`
`
`
`10 Taction maintains that such argument is improper and should be waived, as
`Apple told Taction at a meet and confer that the basis for its indefiniteness argument
`was “generally,” not “cuboid.” Taction Br. at 20 n.7; Dkt. 73-1 ¶ 33.
`
`11 If the Court wishes to construe “cuboid,” Taction provides this definition,
`which is supported by the intrinsic evidence and Apple’s extrinsic evidence.

`
`
`Instead of looking to the intrinsic evidence first to determine the meaning of the
`
`claim, Apple starts and ends with extrinsic evidence—its cherry-picked dictionary
`
`definition—to determine the definition of “cuboid.” This is an incorrect approach that
`
`turns Phillips on its head. Apple’s method ignores the other definitions in its own
`
`dictionary evidence and, more importantly, the intrinsic evidence of the patent.
`

`
`Indefinite
`
`
`
`Apple again alleges the term is indefinite as a term of degree without providing
`
`a standard or reference point for measuring that degree. But Apple overlooks the
`
`language of the claim itself, which provides that reference point. Using the intrinsic
`
`evidence as a guide, the term “relatively” in this limitation means the stiffness (or
`
`resistance to motion) is greater in one direction relative to the other. Taction Br. at 22-
`
`23. Accordingly, a reference point exists and the term is definite.
`
`26
`
`III. Conclusion

`
`Taction respectfully requests that the Court adopt Taction’s proposed
