`Declarations from the Experts
`
`• For Patent Owner
`• Prof. Steven McLaughlin
`• Provost, Georgia Tech
`• Expert in coding technologies
`for magnetic and optical
`recording
`• Appointed by Judge Posner as
`independent technical advisor
`in high‐tech patent case
`• Testimony entirely consistent
`
`• For Petitioners
`• Prof. Emina Soljanin
`• Professor, Elec. & Computer Eng.,
`Rutgers University
`• Three important inconsistencies
`between her declaration and
`other testimony
`• Admitted she is “not familiar
`with optical recording physics,”

`
`Soljanin’s Inconsistent Testimony
`
`1) Soljanin Professed an Inability to Understand
`the Claims
`• In related litigation, testified that five claim terms in
`Challenged Claims are indefinite, i.e. they fail to
`inform, with reasonable certainty, those skilled in
`the art about the scope of the invention.
`• See Ex. 2007.
`• Now finds those claim elements in Okada and Tsang
`without even construing those terms.
`• See Ex. 1010, ¶ 75.

`
`Soljanin’s Inconsistent Testimony
`2) Soljanin Contradicted Herself Regarding What Constitutes a
`“Transition” in Okada
`• Did not define “transitions” in her declaration. See Ex. 1010, Section VI.
`• Testified in her declaration that “1” in the output of Okada’s NRZi
`modulator was a “transition.” See, e.g., Ex. 1010, ¶ 101.
`
`• But, on cross‐examination, testified:
`• 0‐to‐1 and 1‐to‐0 flips in the NRZi modulator are transitions.
`See Ex. 2011, pp. 53‐54.
`• In magnetic recording, transition is “from one polarization to another.”
`See Ex. 2011, p. 56.

`
`Soljanin’s Inconsistent Testimony
`3) Soljanin Contradicted Herself and Petitioners Regarding the j Value
`in Okada
`• Direct testimony: j = 2 in Okada. See, e.g., Ex. 101, ¶ 101.
`
`• Cross examination: j in Okada is 4 … or 8 … or 12. See Ex. 2011, pp. 92‐93.
`• Her own tables (Ex. 1011) show that j can be 20. See Ex. 2017, ¶ 85.
`• Even Petitioners disagree with her, asserting in Petitioners’ Response that
`j=8 if just Rule (2) is considered. See Paper 46, p. 16.
`• Petitioners’ new theory is wrong too; j can be 12 under Rule (2) per LSI’s
`interpretation of “transition.” See Paper 51, pp. 17‐18.

`
`Reading Data from a Magnetic Disk
`
`• A read head generates a readback
`signal from sensing the magnetic
`orientations of the bit regions.
`• A detector detects the written data
`from the readback signal using a
`trellis‐based Viterbi algorithm.
`• Noise in the readback signal
`complicates the detection process.

`
`Media Noise
`
`• Media noise is major noise source in high‐
`density HDDs.
`• Arises because boundaries between bit regions
`of opposite magnetic polarities are not straight.
`Instead, transitions are jagged.
`• Media noise increases as data density increases.
`• Degree and extent of jaggedness depends on the
`sequence written to the disk.
`• Sequences with more transitions have more media
`noise than sequences with fewer or no transitions.

`
`Problem Addressed by ‘601 Patent
`
`T – Transition
`NT – Non‐transition
`
`• Each of the above sequences has at least 2 consecutive transitions
`• Each pair would be “numerically close” with the Viterbi algorithm,
`leading to potential errors
`• Are there ways to encode the data to be written to the disk that
`reduce media noise effects … yet that do not impose a high rate
`penalty?

`
`
`
`DEMONSTRATIVE EXHIBIT—NOT EVIDENCE
`
`Solution of ‘601 Patent
`• Maximum Transition Run (MTR) Codes
`• Use j and k constraints
`• j is maximum number of consecutive transitions
`• k is maximum number of nontransitions between transitions
`• If j=2, sequences with back‐to‐back transitions permitted,
`but 3 consecutive transitions are prohibited
`• Encoder encodes an incoming m‐bit dataword into a n‐bit
`codeword using MTR code
`• n > m
`• N‐bit codeword then written to disk – “recorded waveform”

`
`Solution of ‘601 Patent
`
`• Example m=4, n=5 MTR Code at Fig. 6
`where j=2 and k=8
`• NRZI recording example (where 1
`represents a transition and 0 represents a
`nontransition)
`• No codeword has more than two
`consecutive transitions (represented by 1s)
`• Even if two code words are concatenated:
`• Still no more than two consecutive transitions
`• And no more than eight consecutive
`nontransitions (represented by 0s)

`
`Beauty of MTR Codes
`
`• Reduce errors in reading process by reducing
`sequences that lead to errors (i.e., sequences with
`too many consecutive transitions)
`• Relatively low rate penalty
`As a result, the detector can withstand more noise and/or
`high data density for relatively small rate penalty

`
`• Optical recording system

`source from being turned
`“on” for three consecutive
`cycles
`• Different problem than in
`magnetic recording
`• Eliminates the need for a
`second peak detector

`
`Okada’s Encoding Process
`• First, 8‐13 conversion (element 10 in Fig. 6)
`• 8‐bit dataword converted to 13‐bit codeword
`• Encoding according to either Rule (1)
`or Rule (2) (depending on the dataword)
`• Second, NRZi Modulation (element 6)
`• Output of NRZi Modulator supplied to
`light source (element 3) for writing to
`optical disk
`• “Recorded waveform”
`• Rules (1) and (2) designed so that output of
`NRZi modulator does not have more than 3
`consecutive 1’s

`
`
`
`DEMONSTRATIVE EXHIBIT—NOT EVIDENCE
`
`Okada’s Encoding Process
`
`• 8‐to‐13 Conversion
`• Rule (1): 13‐bit output pattern consists of at least one
`“0” and an even number of “1”s. See Okada at Tables 1‐7.
`• Rule (2): 13‐bit output pattern includes a section consisting
`of “01010” and a second consisting of at least one “0” and
`an even number of consecutive “1”s.
`Ex. 2017, ¶ 71; Ex. 1007
`• NRZi Modulation
`• If bit in output of 8‐to‐13 converter is “0”, the NRZi
`modulated bit is the same as prior bit.
`• If bit in output of 8‐to‐13 converter is “1”, the NRZi
`modulated bit is an inversion of prior bit (0 to 1 or 1 to 0).

`
`Okada’s Encoding Process
`
`Example in Okada
`• 8‐bit input is E8 in hexadecimal (11101000 in binary)
`• Output of 8‐to‐13 converter is 0010100110000
`• Rule (1) – See Table 7
`• 13‐bit pattern, after NRZi modulation, is 0011000100000
`• This pattern written to optical disk, even according Prof. Soljanin
`
`‐ 2nd column is output of Okada’s 8‐13 converter
`‐ 3rd column is output of Okada’s NRZi modulator
`and written to disk.
`
`Ex. 1011
`
`Soljanin Tr. (Ex. 2011), pp. 81‐83.
`• No more than three consecutive 1s, so Okada’s light source is
`not turned ON for three consecutive cycles

`
`
`
` Undisputed expert testimony.
`
`The Federal Circuit has identified these types of extrinsic evidence as

`
`“A dictionary definition has the value of being an unbiased source accessible to the
`public in advance of litigation.”
`
`“[E]xpert testimony can be useful to a court for a variety of purposes, such as to

`• Claim 13 requires “transitions” to be manifested “in the recorded
`waveform”
`• Transition in waveform is a reversal in the magnetic orientation, not 0s or 1s
`• Claim 17 limits recording format to NRZ – “1” represents a positive
`level in the magnetization waveform and “0” represents a negative
`level in the same waveform
`

`Okada Does Not Limit “Transitions”
`
`Petitioners’ Original Theory of Anticipation Fails
`1) As an optical system, Okada does not limit “transitions”
`under UMN’s proper construction
`2) Even under a general definition of “transition” (i.e., a
`change in state), the “1”s in the output of Okada’s NRZi
`modulator are not “transitions”
`• “1”s in the output of Okada’s NRZi modulator turn ON
`Okada’s optical head, which create “lands” in the optical disk.
`So Okada limits consecutive occurrence of the same state
`(“lands”), not changes in state. Ex. 2017, ¶ 79.

`
`The Board Should Decline to Consider
`Petitioners’ New Theory
`Trial Practice Guide Prohibits New Theories in Petitioners’ Reply
`“[Petitioner] chose which grounds of invalidity to assert in its petition
`and it chose not to assert this new one. Unlike district court litigation …
`the expedited nature of IPRs bring with it an obligation for petitioners to
`make their case in their petition to institute.”
`Intelligent Bio‐Systems, Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369 (Fed. Cir. 2016)
`
`“Petitioner may not submit new evidence or argument in reply that it
`could have presented earlier … [O]ur rules require a petition to include
`information sufficient to show how and why the properly construed
`claims are unpatentable over the asserted prior art. … Because
`Petitioner did not [include the theory] in the Petition, we do not
`consider that new theory.”

`Petitioners’ New Theory for Rule (2) Alone –
`Still Fails on The Merits
`
`DEMONSTRATIVE EXHIBIT—NOT EVIDENCE
`
`New Theory Fails for Three Reasons
`1) No “transitions,” properly construed as requiring reversals
`in magnetic orientation
`• Previously addressed in connection with original theory
`2) New theory lacks evidentiary support
`3) Rule 2 alone permits up to 12 consecutive “transitions”

`

`
`2) New theory lacks evidentiary support:
`• No expert testified that Okada’s encoder can operate with only
`one of Okada’s Rules (1) and (2)
`• Okada needs both rules to encode all of the possible 256, 8‐bit
`datawords
`• Petitioners’ “separate method” theory eliminates 84% of
`possible datawords
`• Petitioners have not established that the “Rule (2) standing
`alone” method qualifies as an anticipating reference
`• See Elan Pharm., Inc. v. Mayo Found., 346 F.3d 1051, 1055 (Fed. Cir. 2003)
`(“assertedly anticipating reference must be adequate to enable possession
`of the desired subject matter”).

`Tsang Patent Is Not Prior Art
`
`• Undisputed Background of Inventors’ Disclosures to Tsang
`• Inventors Moon and Bricker authored “Seagate Annual Report”
`• Inventors provided it to Seagate, including Tsang, before filing
`date for Tsang Patent
`• Petitioners concededly rely on portions of Tsang Patent
`that are based on the Seagate Annual Report
`• Inventors tested their invention before filing date for Tsang
`Patent
`• Reasons That Tsang Patent Is Not Prior Art
`• Tsang Patent is not “by another” under § 102(e)
`• Moon and Brickner invented before Tsang

`
`Tsang Patent Is Not Prior Art
`Two Independent Reasons:
`1. Tsang Patent is not “by another,” as required by Section
`102(e)
`2. Tsang Patent not filed “before the invention”
`by Moon and Brickner, as required by Section 102(e)

`

`
`
`
`DEMONSTRATIVE EXHIBIT—NOT EVIDENCE
`
`Tsang Patent Is Not “By Another”
`
`• Tsang Patent is not “by another” because Tsang derived it from
`Moon and Brickner
`• Requirements for “derivation” (see Price v. Symsek, 988 F.2d 1187 (Fed. Cir.
`2003); In re Land, 368 F.3d 866 (CCPA 1966))
`• 102(e) reference patentee learned of applicant’s invention from
`applicant by being associated with applicant
`Undisputed that prior to Jan. 1996 (Tsang Patent filing date), Moon &
`Brickner gave SAR to Seagate and educated Tsang about MTR codes
`• 102(e) reference patentee thereafter describes invention in patent
`application
`Undisputed that Tsang Patent describes MTR codes in patent application
`and cites the SAR as showing prior knowledge of MTR codes
` Petitioners and Soljanin asserted that SAR shows prior invention of MTR
`code

`
`Tsang Patent Is Not “By Another”
`Key Points of Tsang Cited in Petition Rely on SAR
`• Claim element 13[A]: Petition relies on Tsang Patent’s citation to SAR
`(Petition, p. 38)
`• Claims elements 13[B] and [C]: Petition relies on encoder in Tsang
`Patent (Petition, p. 52)
`• SAR discloses encoder.
`
`• Claim element 13[D]: Petition relies on j=2, k=9 MTR code in Tsang
`Patent (Petition, pp. 52‐53)
`• SAR discloses j=2, k=9 MTR codes
`
`Ex. 2025, pp. 7, 10

`Moon and Brickner Invented Before Tsang
`
`• Two components of making an invention
`• Conception
`Moon and Brickner conceived their MTR invention in Spring
`1995
`• Reduction to Practice
`Moon and Brickner actually reduced the MTR invention to
`practice by at least September 1995
`• Tsang’s filing date is Jan. 31, 1996, which is after the
`actual reduction to practice

`• September 1995 SAR further demonstrates conception. Ex.

`• Undisputed that the SAR discloses all elements of
`Challenged Claims. Ex. 2017, ¶¶ 96‐104; Ex. 2016,
`¶¶ 55, 73.
`• SAR provides exemplary logic rules for rate 4/5 code and
`describes how similar logic rules could be used for other rate
`codes. Ex. 2025, p. 9; Ex. 1035, pp. 147‐48.
`• Even Petitioners assert that SAR discloses MTR codes.
`• See Petition, p. 6; Soljanin Decl. (Ex. 1010), ¶ 60.

`
`• Reduction to Practice
`• In 1995, Moon and Brickner used simulations to
`test MTR invention.
`• Simulations corroborated.
`• 601 Patent (Ex. 1001), col. 3:10.
`• 1996 IEEE paper (Ex. 1012), pp. 3933‐34.
`• May 1995 Report to Seagate (Ex. 2033), Fig. 5.
`• September 1995 SAR (Ex. 2025), pp. 17‐18.
`• Simulations included all elements of claim 13. Ex. 2016, ¶ 70.
`• Involved physical encoder. Ex. 1035, pp. 24‐25.
`• Simulations “performed using an actual magnetoresistive (MR)
`head response.” Ex. 2025.

`Tsang Patent Is Not Prior Art Under § 102(g)
`
`DEMONSTRATIVE EXHIBIT—NOT EVIDENCE
`
`• Alleged prior invention under § 102(g) cannot
`be used to cancel a claim in an inter partes
`review because an IPR must be based on prior
`art consisting of patents or printed publications.

`00119, Paper 15 at 17 (PTAB May 3, 2019) (citing 35

`• Petitioners do not refute this.
