`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`
`I.
`
`Introduction
`
` JDS Uniphase, Corp.’s (“JDSU” or “Petitioner”) Petition is wholly
`
`redundant to a previously filed IPR by Cisco Systems, Inc. (“Cisco”)1 and an
`
`improper attempt to do nothing more than bolster the case against U.S. Patent No.
`
`RE42,678 ( “’678 Patent”). In short, the instant Petition amounts to an
`
`impermissible “second bite” at the apple. As such, Patent Owner Capella
`
`Photonics, Inc. (“Capella” or “Patent Owner”) respectfully requests that the Board
`
`not institute trial.
`
`The Board has consistently denied institution of redundant petitions, and
`
`here, Petitioner’s grounds are entirely duplicative of the grounds asserted by Cisco
`
`in IPR2014-01276. 2 The only difference between the two petitions is the simple
`
`substitution by JDSU of one secondary reference (Smith) for another (Sparks), and
`
`
`1 Petitioner is Cisco’s supplier of the optical switches at issue in district
`
`court. See Ex. 2001, pp. 1, 4, 12. Petitioner is obligated under California
`
`Commercial Code § 2312 to indemnify Cisco.
`
`2 See infra Part II (discussing Butamax Advanced Biofuels LLC v. Gevo, Inc.;
`
`Google Inc. v. SimpleAir, Inc.; Unilever, Inc. v. Proctor & Gamble Co.; Medtronic,
`
`Inc. v. Robert Bosch Healthcare Sys., Inc.; Intelligent Bio-Sys. v. Illumina
`
`Cambridge Ltd.; Conopco, Inc. v. Procter & Gamble Co.).

`

`

`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`the only alleged reason for this substitution is that Sparks “has a higher likelihood
`
`of surviving a prior-invention date challenge.” (Petition, p. 2.) Regardless of
`
`whether this is enough to overcome redundancy in the first instance, Patent Owner
`
`never actually set forth a prior invention challenge to Cisco’s Petition, thereby
`
`obviating the alleged necessity of JDSU’s petition.
`
`Petitioner has also used its Petition to improperly bolster the case against the
`
`’678 Patent by fixing errors the Board found in the IPR2014-01276 petition. The
`
`Board has consistently found this tactic improper and contrary to Congress’s intent
`
`in enacting the Leahy-Smith America Invents Act.3
`
`Regardless, the Board should not institute trial because Petitioner has not
`
`shown a reasonable likelihood of success on the merits.
`
`The ’678 Patent claims at least two unique features: (1) multiple fiber
`
`collimators corresponding to and providing an input port and a plurality of output
`
`ports and (2) micromirrors being pivotal about two axes and being continuously
`
`controllable. These features, shown in Figures 1A and 1B (reproduced below),
`
`
`3 See infra Part III (discussing ZTE Corp. v. ContentGuard Holdings, Inc.;
`
`Butamax Advanced Biofuels LLC v. Gevo, Inc.; CustomPlay, LLC v. ClearPlay,
`
`Inc.; Unilever, Inc. v. Procter & Gamble Co.; Conopco, Inc. v. Procter & Gamble
`
`Co.).

`allow the system to route individual channels from the input port to a selected
`
`output port. Because the optical system in the ’678 Patent has multiple fiber
`
`collimators providing multiple ports, the system can route a greater number of
`
`individual channels than systems in the prior art.
`
`Figures 1A and 1B of the ’678 Patent
`Collimators, providing an input
`port and a plurality of output ports
`
`
`
` Micromirror Array 103
`
`
`
`
`
`
`
`
`Optical switches at the time of the invention did not have multiple ports, let
`
`alone multiple fiber collimators to provide the ports, as recited in the ’678 Patent.
`
`Existing systems had a single input port and a single output port. Rather than using
`
`collimators to providing multiple ports, conventional systems used peripheral
`
`components, such as circulators, to both add optical signals to the input port and to
`
`drop optical signals from the output port. (See Ex. 2002, Business Wire, p. 2.)
`
`A circulator is a device that is used to separate optical signals traveling in
`
`opposite directions. Referencing the schematic reproduced
`
`herein, light can enter and exit circulator ports 1, 2, and 3. Light
`
`entering circulator port 1 is emitted from circulator port 2, light
`
`
`
`- 3 -
`
`

`

`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`entering circulator port 2 is emitted from circulator port 3, and light entering
`
`circulator port 3 is emitted from circulator port 1. Circulators were effective to
`
`separate incoming and outgoing optical signals. But optical systems using
`
`circulators were not scalable to a large number of channels because every added
`
`circulator contributed cost, bulk, and insertion loss (i.e., crosstalk between
`
`channels) to the optical system.
`
`To overcome these limitations, the inventors of the ’678 Patent designed an
`
`add/drop optical switch with multiple fiber collimators providing multiple ports.
`
`This multiple port configuration differentiated Capella from competitors because
`
`Capella’s system was reconfigurable and scalable to a large number of channels.
`
`(See Ex. 1001, ’678 Patent, 5:56-58, FIG. 1A (capable of seamlessly adding a port
`
`110-N to the array of ports 110). See also Business Wire, p. 2 (“The introduction
`
`of dynamic reconfigurability will enable service providers to drastically reduce
`
`operating expenses associated with planning . . . by offering remote and dynamic
`
`reconfigurability.”); Ex. 2008, Holliday R-OADMs, p. 61 (“Capella is the only
`
`company to offer a 10-fiber port solution, i.e., one input, one express output, and 8
`
`service ports.”); Ex. 2003, WavePath, pp. 1, 4.)
`
`In the instant Petition, Petitioner attempts to piece together Capella’s
`
`configuration using three main references: (1) U.S. Patent No. 6,498,872 to
`
`Bouevitch et al. (“Bouevitch”); (2) U.S. Patent No. 6,625,340 to Sparks et al.
`
`
`
`- 4 -
`
`

`

`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`(“Sparks”); and (3) U.S. Patent No. 5,661,591 to Lin et al. (“Lin”). The asserted
`
`combination, however, is problematic for the following reasons.
`
`Petitioner combines multiple embodiments of Bouevitch without providing
`
`KSR rationale. And fundamentally, the separate embodiments of Bouevitch are not
`
`combinable. Petitioner points to modifying means 150 shown in Bouevitch Figure
`
`5 and MEMS array 50 shown in Bouevitch Figure 11 (annotated figures
`
`reproduced below) when arguing that Bouevitch explicitly discloses every element
`
`of the independent claims except for mirrors rotatable about two axes.
`
`Bouevitch Figures 5 and 11 Annotated to Show Different Reflection Angles
`
`
`
`
`Petitioner errs in combining these two embodiments because the
`
`embodiments were designed to operate in entirely different optical configurations
`
`and to perform entirely different functions. Modifying means 150 shown in Figure
`
`5 is used in an optical system configured to function as a dynamic gain equalizer
`
`(“DGE”) to control power attenuation. MEMS array 50 shown in Figure 11 is used
`
`in an optical system configured to function as a configurable optical add/drop
`
`multiplexer (“COADM”) to perform switching. The embodiments are also
`
`
`
`- 5 -
`
`

`

`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`different because modifying means 150 uses polarization to control a light beam,
`
`while MEMS array 50 comprises two plain mirrors 51 and 52. Further, the
`
`embodiments are not interchangeable because as shown in the annotations to
`
`Figures 5 and 11, modifying means 150 operates with input and output light beams
`
`in parallel, while MEMS array 50 reflects an input light beam according to the
`
`incident angle of reflection. Contrary to Petitioner’s contentions, a POSA could not
`
`have used modifying means 150 in the system configured to operate with MEMS
`
`array 50.
`
`Petitioner also combines Bouevitch and Sparks. Petitioner contends that
`
`using Sparks’s two-axis mirror in Bouevitch would have been a “simple
`
`substitution.” Petitioner errs because Bouevitch and Sparks are not combinable,
`
`and Petitioner does not reconcile technical differences between Bouevitch and
`
`Sparks. Instead of explaining how the optical systems are combinable, Petitioner
`
`blankly calls the combination a simple substitution of one known optical
`
`component for another. The Board has already held that such conclusory
`
`statements are unsatisfactory. See, e.g., JDS Uniphase Corp. v. Fiber, LLC,
`
`IPR2013-00318, Paper 45 at 36-37 (P.T.A.B. Dec. 5, 2014) (upholding
`
`patentability where Petitioner relied on conclusory statements).
`
`Contrary to Petitioner’s contentions, this case is technologically complex. As
`
`the Board can glean from the applied references and expert reports associated with
`
`
`
`- 6 -
`
`

`

`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`this technology, Petitioner over simplifies issues and leaps to conclusions on
`
`combinability. A micromirror is a small device in the end, but a lot of engineering
`
`disciplines (e.g., electrical engineering, mechanical engineering, physics, and
`
`packaging technology) go into designing a micromirror. (Ex. 2005, Marom Depo.
`
`Tr., 222:13-18.) Instead of saying that using Sparks’s micromirror in Bouevitch
`
`would have been a simple substitution and a POSA only had two types of
`
`micromirrors to choose from, Petitioner’s combinability analysis in the Petition
`
`should have reflected the technological complexities of this case. Because
`
`Petitioner failed to timely and adequately explain how the references are
`
`combinable, the Board should not institute trial.
`
`Additionally, the Board should not institute trial because the asserted
`
`combination does not disclose each and every claim element.
`
`The first reference, Bouevitch, discloses an optical system comprising one
`
`input port and one output port. Like the prior art systems that are described in the
`
`’678 Patent, Bouevitch uses peripheral circulators to add optical signals to the
`
`input port and to drop optical signals from the output port. To compare the fiber
`
`collimators that serve as the ports in the ’678 Patent to the circulators in Bouevitch,
`
`Figure 1A of the ’678 Patent and Figure 11 of Bouevitch are reproduced below.

`
`
`
`Petitioner contends that the circulator ports in Bouevitch read on the claimed
`
`“input port” and “output ports.” But such interpretation is inconsistent with the
`
`’678 Patent, the ’678 Patent’s earliest provisional application, and the underlying
`
`motivation to design an optical switch scalable to a large number of channels. The
`
`’678 Patent and its provisional distinguish circulators from the claimed “ports” and
`
`emphasize that conventional optical systems could not scale to a large number of
`
`channels because the optical systems utilized circulators. The ’678 Patent explicitly
`
`labels the ports “collimators” and says throughout the specification and the claims
`
`that multiple fiber collimators provide the ports. The multiple fiber collimator ports
`
`in the ’678 Patent are not circulator ports. Construing the claimed collimator ports
`
`to read on optical circulator ports is contrary to the ’678 Patent and misapprehends
`
`the capabilities the ’678 Patent brought to the industry.
`
`For the element “micromirrors being pivotal about two axes and being . . .
`
`continuously controllable,” Petitioner uses the second and third references, Sparks
`
`
`
`- 8 -
`
`

`

`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`and Lin. Sparks and Lin, however, do not teach or suggest the claim element.
`
`Petitioner first says Sparks teaches continuous control, but Sparks does not have
`
`support to show that its mirror moves in a continuous fashion. Petitioner then says
`
`Lin teaches continuous control, but as recognized by experts in the field, Lin does
`
`not teach or suggest mirrors pivotal about two axes because Lin only shows a
`
`mirror rotatable along one axis (i.e., control in only one dimension).
`
`Even more problematic than the shortcomings of Sparks and Lin, Petitioner
`
`provides no KSR rationale for combining Sparks and Lin or for combining both
`
`references with Bouevitch. Petitioner fails to show in the Petition that the
`
`combination teaches or suggests micromirrors that are continuously controllable
`
`and pivotal about two axes or that a POSA would have been motivated to combine
`
`the references. These deficiencies cannot be cured, so the Board should not
`
`institute trial.
`
`II. The Board Should Deny Institution at the Outset Because this Inter
`Partes Review Petition is Redundant in View of IPR2014-01276
`
`The Board has discretion under 35 U.S.C. § 325(d) to deny petitions that
`
`present the same or substantially the same grounds as were presented in prior
`
`petitions. See, e.g., Butamax Advanced Biofuels LLC v. Gevo, Inc., IPR2014-
`
`00581, Paper 8 at 11-13 (P.T.A.B. Oct. 14, 2014) (“Allowing similar, serial
`
`challenges to the same patent, by the same petitioner, risks harassment of patent
`
`owners and frustration of Congress’s intent.”) (citing H.R. Rep. No. 112-98, pt. 1,

`
`(P.T.A.B. Jan. 22, 2015) (denying institution in part because a ground was the
`
`same or substantially the same as a ground in a different petition submitted by a
`
`different party); Unilever, Inc. v. Proctor & Gamble Co., IPR2014-00506, Paper
`
`17 at 5-8 (P.T.A.B. Jul. 7, 2014) (denying a second petition when the petitioner did
`
`not justify how the petition differed from its first petition); Medtronic, Inc. v.
`
`Robert Bosch Healthcare Sys., Inc., IPR2014-00436, Paper 17 at 11-12 (P.T.A.B.
`
`June 19, 2014); Intelligent Bio-Sys. v. Illumina Cambridge Ltd., IPR2013-00324,
`
`Paper 19 at 6-7 (P.T.A.B. Nov. 21, 2013).
`
`The Board should exercise its discretion to deny institution of the instant
`
`Petition because all grounds are redundant to grounds already in front of the Board.
`
`(Compare Petition, p. 5 with Cisco Systems, Inc. v. Capella Photonics, Inc.,
`
`IPR2014-01276, Paper 2 at 4 (P.T.A.B. Aug. 12, 2014) (“Cisco Petition”).) The
`
`grounds set forth in both the instant Petition and in IPR2014-01276 are reproduced
`
`below for comparison.

`
`
`The instant Petition presents identical arguments as the petition in IPR2014-
`
`01276, albeit using U.S. Patent No. 6,625,340 to Sparks et al. (“Sparks”) rather
`
`
`
`- 11 -
`
`

`

`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`than U.S. Patent No. 6,798,941 to Smith et al. (“Smith”). (Compare Cisco Petition,
`
`p. 19 (“to the extent Bouevitch does not disclose 2-axis mirrors and their intended
`
`use for power control, both the Smith Patent and the Smith Provisional each does
`
`so”) with Petition, p. 19 (“to the extent Bouevitch does not disclose 2-axis mirrors
`
`and their intended use for power control, Sparks does”).) The arguments are even
`
`supported by substantially the same expert declaration. (Compare Ex. 1029,
`
`Marom Dec. with Ex. 1028, McLaughlin Dec. See also McLaughlin Dec., ¶ 5
`
`“substantial portions of the Marom Declaration are repeated herein without
`
`particular attribution.”).)
`
`To show that Petitioner uses Sparks for the identical elements as Cisco used
`
`Smith, a side-by-side comparison of Cisco’s Smith arguments and Petitioner’s
`
`Sparks arguments is provided below. Internal citations and emphasis are omitted.
`
`1[d]: “individually and continuously controllable”
`
`SMITH: “Smith teaches continuous control of its MEMS mirrors in an analog
`
`manner.” (Cisco Petition, p. 29.)
`
`SPARKS: “Sparks . . . denotes sufficiently fine precision consistent with analog
`
`control.” (Petition, p. 31.)
`
`1[d]: “pivotal about two axes”
`
`SMITH: “Smith discloses a multi-wavelength . . . optical switch including an
`
`array of mirrors tiltable about two axes.” (Cisco Petition, p. 31.)
`
`
`
`- 12 -
`
`

`

`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`SPARKS: “Sparks describes movable micromirrors (16,26), which are . . . capable
`
`of two axis movement.” (Petition, p. 33.)
`
`1[d]: “to reflect corresponding received spectral channels into . . . output ports”
`
`SMITH: “Smith describe[s] how the goal of controlling the MEMS mirrors is to
`
`effect the add/drop process, which includes reflecting the spectral channels to
`
`selected add/drop ports.” (Cisco Petition, p. 33.)
`
`SPARKS: “Sparks disclose[s] switches to redirect a spectral channel to a
`
`particular port.” (Petition, pp. 34-35.)
`
`1[d]: “to control the power of . . . spectral channels coupled into said output ports”
`
`SMITH: “Smith discusses two-axis (two dimensional tilting) for
`
`both switching and power control.” (Cisco Petition, p. 34.)
`
`Specifically, “angular displacement about [one] axis is used for
`
`power control.” (Id.)
`
`SPARKS: “Sparks discusses 2-axis (two dimensional) mirror actuation for both
`
`switching and power control.” (Petition, p. 35.) Specifically, “the
`
`mirrors . . . deliberately misalign the optical beam path . . . . By
`
`non-optimally aligning the optical beam path, the optical beam will
`
`be attenuated.” (Id.)
`
`2: “servo-control assembly”
`
`
`
`- 13 -
`
`

`

`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`
`SMITH: “Smith discloses this servo control
`
`assembly in Fig. 8 . . . in the form of a
`
`controller . . . that receives feedback from an
`
`optical power monitor.” (Cisco Petition, p. 36.)
`
`SPARKS: “Sparks discloses such a servo control
`
`assembly. Sparks discloses a closed-loop servo control
`
`system.” (Petition, p. 37.)
`
`Figure 8 of Smith and Figure 4 of Sparks are both reproduced below with
`
`annotations to show similarities. Controller in Smith is substantially similar to
`
`Control Means in Sparks (annotated in green), Optical Power Monitor (OPM) in
`
`Smith is substantially similar to Power Measurement Means in Sparks (annotated
`
`in red), and 2 x 2 Optical Cross-Connect (OXC) in Smith is substantially similar to
`
`Switching Means in Sparks (annotated in yellow).
`
`3: “maintaining a predetermined coupling of each reflected spectral channel into
`
`
`
`
`
`one of said output ports”
`
`SMITH: “Smith discusses its use of servo-control to achieve a particular degree of
`
`
`
`- 14 -
`
`

`

`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`coupling of a channel to an output port.” (Cisco Petition, pp. 37-38.)
`
`SPARKS: “Sparks discusses its use of servo-control to achieve a particular degree
`
`of coupling of a channel to an output port.” (Petition, p. 39.)
`
`3: “a spectral monitor for monitoring power levels of said spectral channels”
`
`SMITH: “Smith discloses a spectral monitor as optical power monitor (OPM) 156
`
`. . . that measures power.” (Cisco Petition, p. 39.)
`
`SPARKS: “Sparks discloses power measuring means 130 for measuring power.”
`
`(Petition, pp. 40-41.)
`
`3: “processing unit responsive to said power levels”
`
`SMITH: “As for the processing unit, Smith discloses that unit as 220
`
`CONTroller.” (Cisco Petition, p. 40.)
`
`SPARKS: “Sparks expressly describes a processing (controller) unit for its
`
`micromirrors. (Petition, p. 41.)
`
`4: “servo-control assembly maintains said power levels at a predetermined value”
`
`SMITH: “Smith teaches adjusting the mirror positions to adjust the transmitted
`
`power to conform to one or more predetermined criteria.” (Cisco Petition, p. 42.)
`
`SPARKS: “Sparks teaches an optical switch . . . wherein said optical switch is
`
`arranged to misalign the optical beam path so as to provide a predetermined optical
`
`output power.” (Petition, p. 43.)

`

`Case IPR2015-00739 of
`U.S. Patent No. RE42,678
`61: “dynamically and continuously controlling said beam-deflecting elements”
`
`SMITH: “Smith notes that it is well known that power control should be dynamic
`
`and under feedback control since the various wavelength components vary in
`
`intensity with time.” (Cisco Petition, p. 58.)
`
`SPARKS: “Sparks teaches closed-loop 2-axis control which the PHOSITA would
`
`have understood to mean making adjustments to the deflection of the beam in
`
`response to real-time.” (Petition, p. 58.)
`
`
`Petitioner presents two arguments why the grounds are not redundant.
`
`Petitioner first argues that Smith and Sparks are not identical. (Petition, p. 2.)
`
`Merely saying that the cited references are not identical, however, is insufficient to
`
`overcome redundancy. See Conopco, Inc. v. Procter & Gamble Co., IPR2014-
`
`00628, Paper 21 at 8-9 (P.T.A.B. Oct. 20, 2014).
