`
`
`
`STATEMENT OF THE PRECISE RELIEF REQUESTED
`
`Petitioners LG Electronics, Inc. and LG Electronics U.S.A., Inc.
`
`(collectively “LGE” or “Petitioners”), respectfully request that the United States
`
`Patent and Trademark Office (“USPTO”) institute inter partes review (“IPR”)
`
`under 35 U.S.C. § 311–319 and 37 C.F.R. § 42.100 et seq., and cancel claims 1-9
`
`of U.S. Patent No. 6,785,065 (“the ’065 patent”) (Ex. 1001), assigned to Toshiba
`
`Samsung Storage Technology Korea Corporation (“TSST-K” or “Patent Owner”),
`
`as being invalid under 35 U.S.C. § 103(a) (Pre-AIA) in light of the grounds
`
`presented herein.
`
`II.
`
`INTRODUCTION
`
`The ’065 patent claims recite a well-known optical pickup actuator for use in
`
`an optical recording and/or reproducing apparatus, such as an optical disk drive
`
`(ODD). Exhibit 1011, Declaration of Professor Masud Mansuripur, Ph.D. (the
`
`“Mansuripur Decl.”) ¶ 16, 37-42, 52, 55, 69-71; see also Ex. 1001 at 1:16-31.
`
`Optical recording and/or reproducing apparatuses have existed since the 1970’s
`
`and have the same basic components: a turntable, a spindle motor for rotating a
`
`recording medium placed on a turntable, an optical pickup, and a control unit for
`
`supplying control signals to the spindle motor and the optical pickup. Mansuripur
`
`Decl. ¶ 37, 41; see also Ex. 1001 at 1:26-31, 1:57-63, 2:13-18. Optical pickups
`
`include the same basic components: a light source (e.g., a laser), an objective lens
`
`1
`
`
`

`
`LG’s Petition for IPR of U.S. Patent No. 6,785,065
`
`
`for forming a light spot on the recording medium (e.g., optical disk) by focusing
`
`light from the light source, and an actuator for moving the objective lens so as to
`
`place accurately the light spot formed by the objective lens on the recording
`
`medium. Mansuripur Decl. ¶ 41; see also Ex. 1001 at 1:32-40. The actuator
`
`moves the objective lens in a focus direction (up and down relative to the recording
`
`medium surface) to focus accurately the light spot on the disk, a track direction
`
`(horizontally along a radius of the disk) to position the light spot on tracks of the
`
`disk, and a tilt direction to adjust the shape of the light spot. Mansuripur Decl. ¶¶
`
`40-41; see also Ex. 1001 at 1:32-40. Actuators, such as the conventional actuator
`
`illustrated in Fig. 1 of the ’065 patent, included a base, a holder fixed to the base, a
`
`lens support (called a “bobbin” in the ’065 patent) on which the objective lens is
`
`mounted, wires connecting the lens support and the holder, and electron coils and
`
`magnets that, when a current is applied to the coils, move the objective lens.
`
`Mansuripur Decl. ¶ 41; see also Ex. 1001 at 1:57-2:18. The control unit
`
`determines what current(s)/input signal(s) to apply to the coils in order to achieve a
`
`desired movement. For example, when an ODD reads from or writes to a disk, the
`
`objective lens must be both focused and moved in the track direction. Id. ¶ 41, 127.
`
`The ’065 patent describes prior art optical pickup actuators as having coils
`
`on all (four) sides of the bobbin. Ex. 1001 at Fig. 1, 1:64-2:2. This was
`
`purportedly a problem with the prior art. Id. at 2:57-3:7. For instance, optical
`
`2
`
`
`

`
`LG’s Petition for IPR of U.S. Patent No. 6,785,065
`
`
`pickup actuators are very small, and there were problems installing wiring to the
`
`coils due to insufficient space. Id. The ’065 patent contends to solve this problem
`
`by arranging the coils only on two opposite sides of the pickup actuator to secure
`
`free space at the other sides for support members and wiring. Mansuripur Decl. ¶
`
`46; see also Ex. 1001 at Figs. 3-4, 3:9-17, 8:21-30. Part of the purported solution
`
`also involves controlling driving in the focus and tilt directions using combined
`
`focus and tilt coils FC1-FC4 rather than separate focus coils and tilt coils.
`
`Mansuripur Decl. ¶ 46. However, this exact solution was developed by others
`
`years earlier than the inventors of the ’065 patent. Id. at ¶ 47, 69-71.
`
`The prior art references cited in this petition are not listed in the references
`
`cited and were not considered by the Examiner during prosecution of the ’065
`
`patent. Ex. 1001. Instead, the Examiner, without having ever reviewed these
`
`references, allowed the claims of the ’065 patent in a first action allowance.
`
`As set forth herein, each and every feature recited by claims 1-9 of the ’065
`
`patent was disclosed by the prior art, and claims 1-9 would have been obvious to
`
`the skilled person in view thereof. Therefore, there is a “reasonable likelihood that
`
`the petitioners would prevail with respect to at least one of the claims challenged,”
`
`35 U.S.C. § 314(b), and Petitioners request that their Petition for IPR be granted.

`
`of the Petitioners or real parties-in-interest filed a civil action challenging the
`
`validity of a claim of the ’065 patent, see § 42.101(a); (3) Petitioners requesting
`
`this proceeding have not filed this Petition more than one year after the date on
`
`which at least one of the Petitioners, the real parties-in-interest, or privies of
`
`Petitioners was served with a complaint alleging infringement of the ’065 patent,
`
`see § 42.101(b); and (4) Petitioners, the real parties-in-interest, or privies of
`
`Petitioners are not estopped from challenging the claims on the grounds identified
`
`in this Petition, see § 42.101(c).
`
`IV. MANDATORY NOTICES

`
`IDENTIFICATION OF CHALLENGES
`
`Petitioners request inter partes review and cancellation of claims 1-9 of the
`
`’065 patent (the “challenged claims”) as invalid under 35 U.S.C. §103(a) (Pre-
`
`AIA) because they were already taught by the prior art. The following prior art
`
`references provide evidence of the unpatentability of the challenged claims:

`
`The ’065 patent has an effective U.S. filing date of June 19, 2002, and has a
`
`foreign priority claim to a Korean patent filed on June 19, 2001. The state of the
`
`art as admitted by Applicants in the “Description of the Related Art” section of the
`
`’065 patent (“AAPA”) is prior art to the ’065 patent at least under 35 U.S.C. §
`
`102(a) (Pre-AIA). All of the patent references except for Akanuma, Mohri, and
`
`Kanto are available as prior art under § 102(b). Akanuma, Mohri, and Kanto were
`
`filed years before the earliest priority date of the ’065 patent and are available as
`
`prior art under § 102(e) (Pre-AIA). All of the cited references are analogous art to
`
`the claimed invention of the ‘065 patent because they are (1) from the same field of
`
`endeavor as the claimed invention and/or (2) reasonably pertinent to the problem
`
`6
`
`
`

`
`faced by the inventors. See In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004); see

`
`VI. SUMMARY OF THE ’065 PATENT
`
`A. Overview
`
`“An optical pickup performs recording and/or reproduction of information
`
`with respect to a recording medium, such as an optical disk.” Ex. 1001 at 1:27-29.
`
`“The optical pickup includes an objective lens which forms a light spot on the
`
`optical disk by focusing light emitted from a light source.” Id. at 1:32-34. The
`
`optical pickup also includes “an actuator which controls the objective lens in a
`
`track direction, a focus direction, and a tilt direction so as to accurately place the
`
`light spot formed by the objective lens on the optical disk.” Id. at 1:32-37.
`
`B.
`
`Prior Art Optical Pickup Actuators
`
`“[The] conventional optical pickup actuator includes a base 100, a holder
`
`103 fixed to the base 100, a bobbin 107 where an objective lens 105 is mounted,
`
`wires 109 which connect the bobbin 107 to the holder 103, and a magnetic driving
`

`

`
`LG’s Petition for IPR of U.S. Patent No. 6,785,065
`
`
`portion … which moves the bobbin 107 in the track direction, the focus direction,
`
`or the tilt direction.” Ex. 1001 at 1:57-63, Fig. 1 (reproduced below); see also
`
`Mansuripur Decl. at ¶ 43.
`
`
`
`Coils (e.g., focus coils 110, track coils 115, and tilt coils 112) are installed
`
`on all four side surfaces (107a, 107b) of the bobbin 107. Ex. 1001 at Figs. 1, 2A,
`
`2B; 1:64-2:2. The conventional optical pickup actuator includes focus coils 110
`
`and tilt coils 112 on opposite side surfaces 107a of the bobbin 107; and tracking
`
`coils 115 on the other side surfaces 107b of the bobbin 107. Id. “[A] circuit
`
`portion … applies current to the magnetic driving portion.” Id. at 2:13-18. See
`
`also Mansuripur Decl. at ¶ 44.
`
`The ’065 patent addresses purported shortcomings of arranging coils on all
`
`four side surfaces of a bobbin. Ex. 1001 at 2:57-3:7. For instance, due to the very
`
`8
`
`
`

`
`LG’s Petition for IPR of U.S. Patent No. 6,785,065
`
`
`small size of the optical pickup actuator, there may be insufficient space to install
`
`the wires, and “wiring of the coils is complicated.” Id. at 2:57-61, 65-66. Also,
`
`because a magnet is provided at the coils on all four sides of bobbin, the number of
`
`parts constituting the optical pickup actuator increases, and productivity decreases.
`
`Id. at 2:67-3:3. Additionally, the magnets can interfere with the operation of the
`
`spindle motor. Id. at 3:3-7. See also Mansuripur Decl. at ¶ 45.
`
`C.
`
`Purported Solution of the ’065 Patent
`
`Figs. 3 and 4 illustrate the purported invention of the ’065 patent:
`
`
`
` FIG. 3
`
`
`
`
`
`
`
`
`
`
`
`FIG. 4
`
`The ’065 patent purportedly solves the problems with the prior art by (i)
`
`exclusively providing coils (e.g., focus and tilt coils FC1-FC4 and track coils TC1
`9
`
`
`

`
`LG’s Petition for IPR of U.S. Patent No. 6,785,065
`
`
`& TC2) on opposite side surfaces of bobbin; thereby (ii) securing a free space at
`
`the other opposite sides 15b of bobbin 15 (where the coils are not arranged) for
`
`easy installation of the support members 30. Ex. 1001 at Figs. 3-4; 3:9-17; 8:21-
`
`30.15. Although not in every claim, the ’065 patent also includes (iii) controlling
`
`driving the focus and tilt directions using combined focus and tilt coils FC1-FC,
`
`rather than separate focus coils and tilt coils. See also Mansuripur Decl. at ¶ 46.
`
`D.
`
`Purported Solution of the ’065 Patent was Well-Known
`
`Years prior to the ’065 patent, Akanuma and Suzuki both disclosed the exact
`
`same solution. Mansuripur Decl. ¶¶ 47, 69-72. Akanuma discloses an optical
`
`pickup actuator that: (i) exclusively provides coils (e.g., focusing coils 27 and
`
`tracking coils 28 of the drive coil assemblies 21) arranged only on opposite side
`
`surfaces 20 of a bobbin 14; thereby (ii) securing free space at the other opposite
`
`sides of bobbin 14 (where the drive coil assemblies 21 are not arranged) for easy
`
`installation of support members 16; and (iii) controls driving in the focus and tilt
`
`directions together using focusing coils 27 instead of separate focus coils and tilt
`
`coils. Ex. 1002 at 6:51-64, 7:24-27, 42-52, Figs. 5A-5B; see also Mansuripur Decl.
`
`¶¶ 56-60, 69. Annotated versions of Figs. 5A-6 of Akanuma are set forth below
`
`(bobbin 14 is shown in red; focusing coils 27 and tracking coils 28 of the drive coil
`
`assemblies 21 are shown in blue and green, respectively; the support members 16
`
`are shown in pink; and the magnets 26 are shown in orange).

`
`
`

`
`LG’s Petition for IPR of U.S. Patent No. 6,785,065
`
`
`Mansuripur Decl. ¶ 69. As is clearly shown in the figures, the coils 27 and 28 of
`
`Akanuma are arranged only on two sides (top and bottom in Fig. 5A, front and
`
`back sides in Fig. 5B), which frees up space on the other two sides (right and left
`
`sides in the figures) for the support members. Id. ¶ 70; Ex. 1002 at Figs. 5A-6.
`
`Suzuki also discloses an optical pickup actuator that: (i) exclusively provides
`
`coils (e.g., tilting and focusing coils 31X, 31Y, 32X, 32Y and tracking coils 31A
`
`and 32A) on opposite side surfaces of a bobbin 33, id. at; thereby (ii) securing free
`
`space at the other opposite sides of bobbin 33 (where the coils 31A, 31X, 31Y,
`
`32A, 32X, 32Y are not arranged) for easy installation of support members 44; and
`
`(iii) controls driving in the focus and tilt directions together using tilting and
`
`focusing coils 31X, 31Y, 32X, 32Y instead of separate focus coils and tilt coils.

`
`tracking coils 31A and 32A are shown in green, the support members 44 are shown

`
`
`
`
`Mansuripur Decl. ¶ 71. As is clearly shown in the figures, the coils 31A, 31X,
`
`31Y, 32A, 32X, and 32Y are arranged only on two sides (e.g., right and left in Fig.
`
`2), which frees up space on the other two sides (e.g., top and bottom in Fig. 2) for
`
`the support members. Ex. 1003 at Figs. 1-4; Mansuripur Decl. ¶ 71.
`
`For the sake of efficiency, this Petition will focus on Akanuma as the
`
`primary reference; however, Suzuki also teaches all the pertinent features of the
`
`challenged claims. Mansuripur Decl. ¶ 72.
`
`VII. CHALLENGED CLAIMS OF THE ’065 PATENT
`
`
`
`Claim 1 of the ’065 patent is independent. Claims 2-9 depend, directly or
`
`indirectly, from claim 1. Independent claim 1 reads:
`
`1. An optical recording and/or reproducing apparatus for use with
`transferring information with respect to a recording medium,
`comprising:
`
`13
`
`
`

`
`LG’s Petition for IPR of U.S. Patent No. 6,785,065
`
`
`a spindle motor rotating the recording medium;
`an optical pickup including an objective lens and an actuator
`which actuates the objective lens so as to transfer the information with
`respect to the recording medium; and
`a control unit driving the spindle motor and the optical pickup
`to transfer the information with respect to the recording medium and
`controlling the actuator of the optical pickup in the radial, track, tilt
`and focusing directions,
`wherein the actuator comprises:
`a bobbin movably arranged on a base of the actuator;
`at least one focus and tilt coil which drives the bobbin in
`the focus and the tilt directions and at least one track coil which
`drives the bobbin in the track direction arranged on each of
`opposite side surfaces of the bobbin;
`support members which move the bobbin and are
`provided to the other side surfaces of the bobbin, wherein the
`focus and tilt coils and the track coils are not arranged on the
`other side surfaces of the bobbin; and
`magnets arranged to face corresponding sides of the
`opposite side surfaces of the bobbin.
`
`Ex 1001 at 8:38-65.
`
`VIII. PERSON OF ORDINARY SKILL IN THE ART
`
`The relevant field to the invention of the ’065 patent is optical data storage.
`
`Mansuripur Decl. ¶ 34. A person of ordinary skill in the field would have had
`
`familiarity with optical data storage and retrieval devices, including optical
`
`14
`
`
`

`
`LG’s Petition for IPR of U.S. Patent No. 6,785,065
`
`
`recording and/or reproducing apparatuses having optical pickup actuators, and at
`
`least a Bachelor of Science degree in electrical engineering, computer engineering,
`
`and/or physics and 2-5 years of experience working in the field of optical data
`
`storage and retrieval, or a comparable amount of combined education and
`
`equivalent industry experience in optical data storage and retrieval. Id. ¶ 35.
`
`IX. CLAIM CONSTRUCTION
`
`In an inter partes review, a claim in an unexpired patent is to be given its
`
`“broadest reasonable interpretation in light of the specification in which it
`
`appears.” 37 C.F.R. § 42.100(b); see also In re Cuozzo Speed Techs., LLC, 778
`
`F.3d 1271, 1279 (Fed. Cir. 2015).1 The broadest reasonable construction must be
`
`consistent with the construction that one of ordinary skill in the art would reach
`
`and must take into account any special definition given to a claim term in the
`
`specification. In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d 1359, 1369 (Fed. Cir.
`
`2004). The following contains the proposed terms for construction in this
`
`proceeding along with proposed constructions. All other terms, not presented
`
`below, should be given their plain and ordinary meaning. Mansuripur Decl. ¶ 23,
`
`1 Because the claim construction standard in an IPR is different than that used in
`
`litigation, Petitioners expressly reserve the right to present different constructions
`
`of terms in the related litigation. See In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d
`
`1359, 1369 (Fed. Cir. 2004).

`
`

`

`
`
`by Patent Owner.
`
`A.
`
`“bobbin”
`
`The specification and drawing figures of the ’110 patent describe and show
`
`that the bobbin is the structure upon which the objective lens is mounted. See Ex.
`
`1001 at Figs 1, 3, 4; 1:59 (“a bobbin 107 where an objective lens 105 is mounted”);
`
`5:12-13 (“a bobbin 15 on which an objective lens 14 is mounted”). Therefore,
`
`when given its broadest reasonable interpretation in light of the specification of the
`
`’065 patent, the claim term “bobbin” means “a structure where an objective lens is
`
`mounted.” Mansuripur Decl. ¶ 54.
`
`X. GROUND 1 – CLAIMS 1-2 AND 5-9 ARE OBVIOUS OVER
`AKANUMA ALONE OR IN COMBINATION WITH ONE OR
`MORE OF THE AAPA, KIM, IKEGAME, AND MOHRI
`
`Claims 1-2 and 5-9 of the ’065 patent would have been obvious under 35
`
`U.S.C. § 103(a) based on Akanuma alone or in view of the AAPA, Kim, Ikegame,
`
`and/or Mohri.
