`Case IPR2015-00060
`Patent 7,421,032
`
`
`I.
`
`INTRODUCTION
`
`The Board should not institute inter partes review (IPR) on claims 1, 8, 10,
`
`18, 19, and 22 of U.S. Patent No. 7,421,032 (“the ‘032 patent”) because petitioner,
`
`Hughes Network Systems, LLC and Hughes Communications, Inc. (“Petitioner” or
`
`“Hughes”), has filed a fatally flawed petition and has not met its burden of
`
`showing it has a reasonable likelihood of prevailing on any of its proposed grounds
`
`of unpatentability.
`
`The ‘032 patent represents a seminal improvement to coding systems and
`
`methods used for digital satellite transmission. It discloses an ensemble of codes
`
`called irregular repeat-accumulate (IRA) codes, which are specific types of error-
`
`correcting codes. These IRA codes enable a transmission rate close to the
`
`theoretical limit, while also providing the advantage of a low encoding complexity.
`
`See, e.g., Ex. 2001 p. 1711 (noting inventors’ unique contribution). Moreover, the
`
`current industry standard for digital satellite transmissions uses channel codes that
`
`are the claimed IRA codes. This digital satellite transmission standard is titled
`
`“Digital Video Broadcasting (DVB); Second generation framing structure, channel
`
`coding and modulation systems for Broadcasting, Interactive Services, News
`
`Gathering and other broadband satellite applications” (the “DVB-S2 standard”).
`
`Experts in the industry widely credit the involved inventors for the IRA codes that
`
`the DVB-S2 standard uses. See, e.g., Ex. 2002 p. 0001, n.8; see also Ex. 2003 p.
`
`0001, n.8.
`
`The ‘032 patent is directed to serial concatenation of interleaved
`
`-1-
`
`

`

`Case IPR2015-00060
`Patent 7,421,032
`
`
`convolutional codes forming turbo-like codes. For example, claim 1 of the ‘032
`
`patent recites the following:
`
`A method comprising:
`
`receiving a collection of message bits having a first sequence in a
`
`source data stream;
`
`generating a sequence of parity bits, wherein each parity bit “xj” in the
`
`sequence is in accordance with the formula
`
`
`
`
`
`
`
`
`
`
`
`where
`
`“xj-1” is the value of a parity bit “j-1,” and
`
`
`
`
`
`
`
`is the value of a sum of “a” randomly chosen irregular repeats of the message bits; and
`
`making the sequence of parity bits available for transmission in a
`
`transmission data stream.
`
`As discussed further below, the petition can be dismissed for a number of
`
`reasons. For example, the petition fails to properly identify all real parties-in-
`
`interest, a fatal deficiency that cannot be cured, given that the earliest filing date
`
`that could be accorded to the corrected petition would not fall within the one-year
`
`period specified in 35 U.S.C. § 315(b).1 While the Board can deny institution
`
`
`
`1 Petitioner has filed six petitions for inter partes review: IPR2015-00059,
`
`IPR2015-00060, IPR2015-00061, IPR2015-00067, IPR2015-00068, and IPR2015-
`
`00081. All six petitions similarly fail to properly name all real parties-in-interest.
`
`-2-
`
`

`

`Case IPR2015-00060
`Patent 7,421,032
`
`
`based on this reason alone and without considering the merits, also fatal to the
`
`proposed grounds is Petitioner’s failure to establish that the two primary references
`
`relied upon—Frey and Divsalar—even qualify as prior art printed publications.
`
`The petition suffers from other deficiencies as well. Significantly, the proposed
`
`grounds of challenge fail to demonstrate that each feature of claims 1, 8, 10, 18,
`
`19, and 22 of the ‘032 patent is found in the prior art. Accordingly, institution of
`
`inter partes review should be denied.
`
`II. THE PETITION FAILS TO IDENTIFY REAL PARTIES-IN-
`INTEREST
`
`As a threshold matter, the petition should be dismissed because Hughes
`
`failed to identify all real parties-in-interest as required by 35 U.S.C. § 312(a)(2)
`
`and 37 C.F.R. § 42.8(b)(1). The petition identifies only Hughes Network Systems,
`
`LLC and Hughes Communications, Inc. as real parties-in-interest.2 It at least fails
`
`to identify EchoStar Corporation (“EchoStar”), even though Hughes is the wholly
`
`owned subsidiary of EchoStar, and DISH Network Corporation, DISH Network
`
`L.L.C. and dishNET Satellite Broadband L.L.C. (collectively, “DISH”), even
`
`though EchoStar and DISH are under common control.3 The existence of
`
`
`
`2 While the petition notes that “EchoStar Corporation is the parent of Hughes
`
`Satellite Systems Corporation, which is the parent of Hughes Communications,
`
`Inc.,” it does not identify EchoStar as a real party-in-interest. Pet. p. 1.
`
`3 The decision to mention EchoStar but not identify it a real party-in-interest
`
`was not a mere oversight, but a strategic decision. Caltech asserted the ‘032 patent
`
`-3-
`
`

`

`Case IPR2015-00060
`Patent 7,421,032
`
`
`financially controlling interests, closely intertwined business relationships,
`
`overlapping ownership and management, indemnification agreements, shared
`
`counsel and common litigation strategy clearly establish under the totality of the
`
`circumstances that EchoStar and DISH are real parties-in-interest to this
`
`proceeding. Petitioner’s failure to identify them as real parties-in-interest is fatal to
`
`the petition.
`
`A. The Real Party-In-Interest Requirement
`
`The requirement regarding real parties-in-interest is clear: “A petition [for
`
`inter partes review] may be considered only if . . . [it] identifies all real parties in
`
`interest.” 35 U.S.C. § 312(a)(2). Identification of real parties-in-interest assists
`
`“members of the Board in identifying potential conflicts” and assures “proper
`
`application of the statutory estoppel provisions.” Trial Practice Guide, 77 Fed.
`
`Reg. 48,759 (Aug. 14, 2012). The requirement “seeks to protect patent owners
`
`from harassment via successive petitions by the same or related parties, to prevent
`
`parties from having a ‘second bite at the apple,’ and to protect the integrity of both
`
`
`
`against Hughes in federal district court and named DISH Network Corporation,
`
`DISH Network L.L.C., and dishNET Satellite Broadband L.L.C. as co-defendants.
`
`Ex. 1021 p. 2. On September 30, 2014, Caltech filed a motion for leave to amend
`
`its complaint to add EchoStar as a defendant, and the motion was pending when
`
`Hughes’s IPR was filed. Ex. 2004. Hughes and EchoStar surely recognized at the
`
`time that stating EchoStar was a real party-in-interest would negatively impact
`
`their opposition to the motion.

`Patent 7,421,032
`
`
`the USPTO and Federal Courts by assuring that all issues are promptly raised and
`
`vetted.” Id.
`
`Real party-in-interest analysis is “highly fact-dependent” and judged by the
`
`totality of the circumstances rather than any “bright-line test.” Id. There are a
`
`number of relevant factors, including, but not limited to: (1) an agreement to be
`
`bound; (2) pre-existing substantive legal relationships between the named and
`
`unnamed parties, including preceding and succeeding owners, and assignee and
`
`assignor; (3) adequate representation by someone with the same interests, such as a
`
`trustee or fiduciary; (4) assumption of control over the proceeding; (5) agency; and
`
`(6) a special statutory scheme expressly foreclosing successive litigation, such as
`
`bankruptcy and probate proceedings. Taylor v. Sturgell, 553 U.S. 880, 893–895,
`
`893 n.6 (2008); see also 77 Fed. Reg. at 48,759 (citing Taylor factors). “A
`
`common consideration is whether the non-party exercised or could have exercised
`
`control over a party’s participation in the proceeding.” 77 Fed. Reg. at 48,759.
`
`The non-party’s participation may be overt or covert, and the evidence may be
`
`direct or circumstantial, but the evidence as a whole must show that the non-party
`
`possessed control, or the ability to control, from a practical standpoint. Gonzalez
`
`v. Banco Cent. Corp., 27 F.3d 751, 759 (1st Cir. 1994).
`
`B.
`
`The Petition Fails To Identify Real Parties-In-Interest
`
`
`1.
`
`EchoStar Is a Real Party-In-Interest
`
`Here the relevant factors, including a parent/subsidiary relationship and a
`
`financially controlling interest, suggest that EchoStar is a real party of interest that
`
`-5-
`
`

`

`Case IPR2015-00060
`Patent 7,421,032
`
`
`should have been named in the petition.
`
`First, control can be inferred from EchoStar’s “financially controlling
`
`interest” in Hughes. See Zoll Lifecor Corp. v. Philips Elecs. N. Am. Corp.,
`
`IPR2013-00609, Paper 15 at 10 (PTAB Mar. 20, 2014) (“financially controlling
`
`interest” significant); see also 77 Fed. Reg. at 48,617 (same). Here there can be no
`
`doubt as to the existence of a financially controlling interest because Hughes is a
`
`wholly owned subsidiary of EchoStar. Ex. 2005 ¶ 4 (citing Ex. 1021 ¶ 4). In
`
`EchoStar’s SEC filings, Hughes is referred to as a “segment” of EchoStar and
`
`Hughes is presented as a central and essential component of EchoStar. Ex. 2006
`
`pp. 8, 11-13. Put simply, for all purposes relevant to Hughes’ petition, EchoStar is
`
`Hughes. See Copperweld Corp. v. Independence Tube Corp., 467 U.S. 752, 771
`
`(1984) (“A parent and its wholly owned subsidiary have a complete unity of
`
`interest. Their objectives are common, not disparate; their general corporate
`
`actions are guided or determined not by two separate corporate consciousnesses,
`
`but one.”). Thus EchoStar is a real party-in-interest.
`
`Second, it is clear that EchoStar had the opportunity to control and could
`
`have controlled Hughes’ participation in these proceedings. See Zoll, IPR2013-
`
`00609, Paper 15 at 10-11; 77 Fed. Reg. at 48,759 (“[I]t should be enough that the
`
`nonparty has the actual measure of control or opportunity to control that might
`
`reasonably be expected between two formal coparties.”). Numerous documents
`
`demonstrate that legal affairs are jointly and commonly controlled between Hughes
`
`and EchoStar. EchoStar and Hughes share the same internal legal team including
`
`-6-
`
`

`

`Case IPR2015-00060
`Patent 7,421,032
`
`
`the same General Counsel, who “is responsible for all legal and government affairs
`
`of EchoStar and its subsidiaries” (Ex. 2007 p. 2), as well as an Associate General
`
`Counsel. Ex. 2008 p. 1. Moreover, a parent corporation has a “real interest” in the
`
`affairs of its subsidiary and thus EchoStar had a right to control the proceeding
`
`involving Hughes. See Dalton v. Honda Motor Co., 425 F. App’x 886, 890 (Fed.
`
`Cir. 2011). Given the fact that the same legal team controls legal decision-making
`
`responsibilities for both EchoStar and Hughes, it is beyond dispute that EchoStar
`
`“could have exercised control over [Hughes]’s participation in [the] proceeding.”
`
`77 Fed. Reg. at 48,759.4 It is actually inconceivable here that EchoStar lacked
`
`control, or ability to control. That too makes EchoStar a real party-in-interest.
`
`
`2.
`
`DISH Is a Real Party-In-Interest
`
`Examination of the Taylor factors and DISH’s financially controlling
`
`interest in Hughes, among other things, suggest that DISH is a real party-in-interest
`
`that should have been disclosed in the petition.
`
`First, DISH and EchoStar (Hughes’s parent) are under common control
`
`because the controlling shareholder of DISH has a “financially controlling interest”
`
`in Hughes. See Zoll, IPR2013-00609 (Paper 15) at 10; Fed. Reg. 48,617. In fact,
`
`EchoStar and DISH literally were the same company until the DISH Network
`
`service brand was spun off as DISH Network Corporation on January 1, 2008. Ex.
`
`2005 ¶ 9. While EchoStar and DISH are now technically separate entities, a
`
`substantial majority of the voting power of both companies is owned by Charles
`
`
`
`4 All emphasis added unless otherwise noted.
`
`-7-
`
`

`

`Case IPR2015-00060
`Patent 7,421,032
`
`
`W. Ergen, who acts as Chairman of both companies. Ex. 2006 p. 8. Mr. Ergen
`
`possesses approximately 80.8% of the total voting power of EchoStar and 85.1%
`
`of the voting power of DISH; he has the ability to elect a majority of directors and
`
`to control all matters requiring stockholder approval at both companies, making
`
`both EchoStar and DISH “controlled companies” under NASDAQ listing rules.
`
`See id. at 42-43; Ex. 2009 p. 47. EchoStar and DISH are under “common control”
`
`as explicitly represented in public documents. Ex. 2010 p. 15 (“EchoStar and
`
`DISH Network are entities under common control.”). Additionally, transactions
`
`between EchoStar and DISH are not even considered arm’s length transactions
`
`because of the common ownership and management. Ex. 2006 p. 7 (“We have
`
`potential conflicts of interest with DISH Network due to our common ownership
`
`and management.”). Thus DISH is a real party-in-interest.
`
`Second, the close relationship between Hughes, EchoStar, DISH indicates
`
`that the three companies remain so inextricably intertwined such that all are real
`
`parties-in-interest. See 77 Fed. Reg. at 48,760 (non-party’s “relationship with the
`
`petitioner” is relevant to real party-in-interest analysis). When DISH spun off of
`
`EchoStar, DISH entered into agreements to provide EchoStar with management
`
`and administrative services, including legal services. Ex. 2006 pp. 24, 195. DISH
`
`and EchoStar have overlapping directors and executive officers, many of whom
`
`have financial interests in both companies, including Mr. Ergen and an Executive
`
`Vice President “responsible for the development and implementation of advanced
`
`technologies that are of potential utility and importance to both.” Id. pp. 43, 198.
`
`-8-
`
`

`

`Case IPR2015-00060
`Patent 7,421,032
`
`
`DISH’s General Counsel, who “is responsible for all legal and government affairs
`
`for DISH Network and its subsidiaries,” is also an EchoStar director. Ex. 2009
`
`p. 30. Here the companies are so intertwined and there is so much “corporate
`
`blurring” that both entities should be considered real parties-in-interest, in addition
`
`to Hughes. See Atlanta Gas Light Co. v. Bennett Regulator Guards, Inc.,
`
`IPR2013-00453, Paper 88 at 6, 11 (PTAB Jan. 6, 2015). This is yet another
`
`reason why DISH should be considered a real party-in-interest.
`
`Third, the highly dependent legal and business relationships between
`
`Hughes, EchoStar and DISH also suggest that the three companies share a common
`
`interest in the IPR proceedings and a motive to control. See Paramount Home
`
`Entertainment Inc. v. Nissim Corp., IPR2014-00961, Paper 11 at 8 (PTAB Dec. 29,
`
`2014) (parties to patent-related litigation had “documented interest” in invalidating
`
`patent). As discussed above, one of the potentially infringing products in the
`
`district court litigation is a set-top box used by DISH. EchoStar is the sole supplier
`
`of DISH’s set-top boxes. Ex. 2009 p. 16. Moreover, DISH Network has
`
`historically been “the primary customer of our EchoStar Technologies segment,”
`
`accounting for 90.1%, 76.9% and 79.4% of segment revenue for the years ended
`
`December 31, 2013, 2012 and 2011, respectively. Ex. 2006 p. 10. Finally, Hughes
`
`has an agreement with DISH through 2024 to distribute satellite internet services
`
`under DISH’s dishNET brand. Ex. 2006 p. 11; Ex. 2009 pp. 200-201. The legal,
`
`strategic, and operational relationships illustrate a highly interdependent, triangular
`
`relationship between these entities.
`
`-9-
`
`

`

`Case IPR2015-00060
`Patent 7,421,032
`
`
`This strategic triangular alignment creates
`
`strong commonality of interest and makes lack of
`
`control and coordination between the three
`
`virtually inconceivable.
`
`Fourth, an indemnification agreement at
`
`the time of the DISH spin-off suggests that DISH has a “financially controlling
`
`interest” and a “pre-existing substantive legal relationship” with EchoStar and thus,
`
`by extension, Hughes. See Taylor, 553 U.S. at 893–895; 77 Fed. Reg. at 48,759.
`
`In the spin-off, DISH distributed its digital set-top box business and infrastructure
`
`and other assets and liabilities to EchoStar.5 Ex. 2006 p. 8. As part of the deal,
`
`DISH is contractually obligated to indemnify EchoStar “for any liabilities or
`
`damages resulting from intellectual property claims relating to the period prior to
`
`the Spin-off as well as DISH Network’s acts or omissions following the Spin-off.”
`
`Id. pp. 174, 186-188. EchoStar publicly acknowledges that it is the ultimate source
`
`of the DISH and Hughes products at issue in the Caltech infringement suit,
`
`including DISH’s set-top box receivers and Hughes’ satellite broadband products.
`
`Ex. 2010 p. 32 (“Caltech claims that the HopperTM set-top box that we [EchoStar]
`
`design and sell to DISH Network, as well as certain of our Hughes segment’s
`
`satellite broadband products and services, infringe the asserted patents by
`
`
`
`5 Indeed, here there could be said to be a pre-existing substantive legal
`
`relationships between “preceding and succeeding owners” of the potentially
`
`infringing products under the second Taylor factor. See Taylor, 553 U.S. at 894.
`
`-10-
`
`

`

`Case IPR2015-00060
`Patent 7,421,032
`
`
`implementing the DVB-S2 standard.”). EchoStar also publicly acknowledges that
`
`“[w]e [EchoStar, Hughes, and DISH] intend to vigorously defend this case.” Id.
`
`This establishes not only a financially controlling interest, but also “an agreement
`
`to be bound” under the first Taylor factor and a “pre-existing substantive legal
`
`relationship” under the second. See Taylor, 553 U.S. at 893-94. This too makes
`
`DISH a real party-in-interest.
`
`Fifth, there is substantial evidence that EchoStar and DISH have participated
`
`in and actually exercised control over this proceeding and the related litigation.
`
`EchoStar’s subsidiary (Hughes) and DISH are co-defendants in the federal action
`
`brought by Caltech in the Central District of California.6 EchoStar’s subsidiary
`
`(Hughes) and DISH are represented by the same counsel in that litigation and have
`
`acted in concert throughout the litigation, whether under a joint defense agreement
`
`or otherwise. Ex. 2011 p. 1 (“Counsel of record for the following party or parties:
`
`Dish Network Corporation, Dish Network LLC Hughes Communications Inc.,
`
`Hughes Network Systems LLC, dishNET Satellite Broadband LLC”).
`
`The companies jointly responded to Caltech’s complaint (Ex. 2005 pp. 1, 3),
`
`and their cooperation has continued throughout, including the joint filing of
`
`invalidity contentions. Ex. 2012; Ex. 2014. At the initial scheduling conference
`
`on April 7th, 2014, the companies even jointly informed the district court they
`
`
`
`6 As noted above, Caltech’s motion to formally add EchoStar as a defendant
`
`was pending before the district court at the time the companies filed their petition
`
`for inter partes review.

`There was no distinction to be made between particular defendants, rather
`
`the defendants represented they collectively anticipated bringing IPR challenges at
`
`the patent office. The companies subsequently filed the IPRs, with overlap
`
`between district court litigation counsel for Hughes and Dish, and IPR counsel in
`
`this proceeding. 7
`
`The companies have, in fact, advanced in lock step throughout the course of
`
`
`

`
`III) is currently counsel for both Hughes and DISH in the district court proceeding,
`
`although he just recently requested to withdraw from the district court proceeding.

`
`
`the litigation. It is inconceivable that control over development of prior art
`
`identification and argument, which is similarly reflected in both the PTAB and
`
`district court invalidity attacks, rested solely with one defendant, particularly
`
`where both parties are represented by the same counsel at the district court (with
`
`overlap in counsel at the PTAB), and acted uniformly throughout the litigation.
`
`Moreover, a comparison of the arguments advance in the district court
`
`litigation and the arguments advanced in this proceeding suggests a common
`
`litigation strategy and, therefore, control. See Zoll, IPR2013-00609, Paper 15 at 12
`
`(“unified actions” in “multi-state patent war” indicative of control). Indeed, the
`
`prior art and arguments advanced in the district court litigation are the same prior
`
`art and arguments raised in the petition. See Ex. 2012 pp. 30-46; Ex. 2014 pp. 3-4.
`
`Moreover, as noted above, there is overlap between district court litigation counsel
`
`for Hughes and Dish, and IPR counsel in this proceeding. The existence of
`
`common counsel and common arguments, as well as joint representations to the
`
`district court regarding the IPRs, strongly suggests a common litigation strategy.
`
`Such “unified action” provides, at a minimum, circumstantial evidence of control.
`
`This is more than ample evidence to warrant denial of the petition for failure
`
`to name all real parties-in-interest, particularly under the totality of circumstances.
`
`C.
`
`Failure to Identify Real Parties-in-Interest Is Fatal to the Petition
`
`As demonstrated above, the petition fails to identify all real parties-in-
`
`interest and thus is incomplete. See Zoll, IPR2013-00609, Paper 15 at 16-17.
`
`Incomplete petitions are not accorded a filing date, and thus the petition is not
`
`-13-
`
`

`

`Case IPR2015-00060
`Patent 7,421,032
`
`
`entitled to its October 2014 filing date. See 37 C.F.R. § 42.106(b); see also
`
`Zoll, IPR2013-00609, Paper 15 at 16-17 (failure to name all real parties-in-
`
`interest is a substantive deficiency requiring a new filing date). Moreover,
`
`correcting the omission through amendment would be futile here because, even
`
`if corrected, the earliest filing date that could be accorded to the petition would
`
`not fall within the one-year period specified in 36 U.S.C. § 315(b) for at least
`
`one real party-in-interest. Nintendo of Am. Inc. v. Motion Games, LLC,
`
`IPR2014-00164, Paper 29 at 2 (PTAB 2014); see also Pet. p. 1 (noting Nov. 12,
`
`2013 effective service date). According, the Board should dismiss the petition
`
`and deny institution of inter partes review on these grounds. See Zoll, IPR2013-
`
`00609, Paper 15 at 16-17.
`
`III. EXPERT QUALIFICATIONS AND HINDSIGHT
`
`In view of Petitioner’s failure to properly name all real parties-in-interest,
`
`and the futility of belatedly correcting the omission, the Board need not address the
`
`Petitioner’s invalidity arguments – which are without merit.
`
`Should the Board review the grounds of challenge, as an initial matter, any
`
`such review should attribute little, if any, weight to the declaration testimony of
`
`Petitioner’s expert Dr. Pfister, submitted as Ex. 1010.8 According to Petitioner, the
`
`
`
`8 Numerous paragraphs of Ex. 1010 are not cited or relied upon anywhere in the
`
`petition and can be ignored for this reason as well. In fact, Petitioner’s exhibit list
`
`is populated with numerous exhibits that are cited nowhere in the petition. Any
`
`exhibit, or content of an exhibit, not specifically cited in the petition should be

`
`
`ordinary level of skill in the art is “very high,” requiring either a “Ph.D. in
`
`electrical or computer engineering with emphasis in signal processing,
`
`communications, or coding, or a master’s degree in the above area with at least
`
`three years of work experience in this field at the time of the alleged [sic]
`
`invention.” Pet. p. 12; Ex. 1010 ¶ 44. Dr. Pfister, however, states he does not meet
`
`his own definition as a person of ordinary skill in the art at the time of filing. Ex.
`
`1010 ¶ 45. He is right about this, at least because his graduate work mainly
`
`occurred after the critical date. Id. at ¶ 4. Dr. Pfister cannot speak with first-hand
`
`knowledge about what those in the art at the relevant time knew and could do.
`
`Under Board precedent, Dr. Pfister’s testimony can be accorded no weight.
`
`See Schott Gemtron v. SSW Holding Co., IPR2013-00358, Paper 106 at 17-18
`
`(PTAB 2014) (discounting expert testimony for lack of sufficient post-degree
`
`experience). Indeed, the fact that an expert witness was not an expert in the
`
`relevant field at the relevant time is grounds for not considering the testimony at all
`
`in some instances. Flex-Rest, LLC v. Steelcase, Inc., 455 F.3d 1351, 1360-61 (Fed.
`
`Cir. 2006).
`
`In this case, Dr. Pfister’s testimony can be largely discounted. Dr. Pfister
`
`cannot reliably testify about how those of ordinary skill in the art would have
`
`understood the art because he only achieved that level of proficiency after the
`
`inventors on the present invention had been publically recognized for their solution
`
`
`
`deemed irrelevant to the content of the petition and wholly ignored. See e.g., 37
`
`C.F.R. § 42.22(a)(2).

`
`
`to the problem. The only way for Dr. Pfister to avoid impermissible hindsight
`
`would be to forget his hard-earned knowledge after the critical date, while he was
`
`still working on his doctorate, and cast his imagination back to the perspective of a
`
`person he never was.
`
`This point is particularly relevant in this IPR for several reasons. Numerous
`
`paragraphs of Dr. Pfister’s declaration, particularly in the section “Background on
`
`the Relevant Technology,” fail to cite a single reference or shred of evidence in
`
`support of proffered commentary. Ex. 1010 ¶¶ 16-23, 25, 27; cf. § 42.65(a) (expert
`
`testimony without basis accorded no weight). Much of the commentary simply
`
`repeats Hughes’ and DISH’s litigation positions. Dr. Pfister, however, lacks
`
`personal knowledge of either the background of the technology or developments in
`
`the field at the relevant time. Instead, he relies on impermissible hindsight
`
`reconstruction of the state of the art formed in the context of supporting a litigation
`
`position. As a consequence, his testimony cited in the petition is often barely
`
`explained or conclusory in nature, while failing to identify any supporting facts or
`
`data, such as the assertion that that “the broadest reasonable interpretation of
`
`[claim 1] includes the case where a=1.’” Pet. p. 20 (citing Ex. 1010 ¶ 66)
`
`(discussed below). Curiously, even when Dr. Pfister is presented as a fact witness
`
`rather than an expert witness, he asserts critical facts without corroboration or
`
`stating a basis in personal knowledge. See, e.g., Ex. 1010 ¶ 29 (appearing to testify
`
`about the availability of a web posting); cf. Fed. Reg. Evid. 602 (requiring personal
`
