`
`Case 2:13-cv-01112-JRG Document 459 Filed 03/20/15 Page 4 of 144 PageID #: 24026
`
`I. BACKGROUND
`
`
`
`Plaintiff brings suit alleging infringement of United States Patents No. 6,963,859 (“the
`
`‘859 Patent”), 7,523,072 (“the ‘072 Patent”), 7,225,160 (“the ‘160 Patent”), 7,269,576 (“the ‘576
`
`Patent”), 8,370,956 (“the ‘956 Patent”), 8,393,007 (“the ‘007 Patent”) (collectively, the “Trusted
`
`Repository Patents” or “Stefik Patents”), 7,774,280 (“the ‘280 Patent”), 8,001,053 (“the ‘053
`
`Patent”) (collectively, the “Meta Rights Patents,” “Nguyen/Chen Patents,” or “Nguyen Patents”),
`
`and 8,583,556 (“the ‘556 Patent,” also referred to as the “Transaction Tracking Patent” or the
`
`“Dunkeld Patent”) (all, collectively, “the patents-in-suit”). (Dkt. No. 304, Exs. A-I.)
`
`
`
`The parties have presented the patents-in-suit as three distinct groups, as set forth above,
`
`and the Court addresses those three groups in turn, below.
`
`
`
`The Court heard oral arguments on February 6, 2015. The parties did not present oral
`
`argument as to all disputed terms. Instead, “[g]iven the large number of disputed claim terms,”
`
`the parties chose to present oral arguments on terms identified in the parties’ January 23, 2015
`
`Joint Notice Regarding Markman Hearing. (Dkt. No. 365.) The parties also presented oral
`
`argument regarding one additional group of terms identified by the Court, namely “nonce” and
`
`“random registration identifier” in the Stefik Patents. The parties did not present oral arguments
`
`regarding any other disputed terms and instead submitted those disputes on the briefing.
`
`II. LEGAL PRINCIPLES
`
`
`
`It is understood that “[a] claim in a patent provides the metes and bounds of the right
`
`which the patent confers on the patentee to exclude others from making, using or selling the
`
`protected invention.” Burke, Inc. v. Bruno Indep. Living Aids, Inc., 183 F.3d 1334, 1340 (Fed.
`
`Cir. 1999). Claim construction is clearly an issue of law for the court to decide. Markman v.
`
`4
`Patent Owner Content Guard Holdings, Inc. - Exhibit 2001, p. 4
`
`

`
`Case 2:13-cv-01112-JRG Document 459 Filed 03/20/15 Page 5 of 144 PageID #: 24027
`
`Westview Instruments, Inc., 52 F.3d 967, 970-71 (Fed. Cir. 1995) (en banc), aff’d, 517 U.S. 370
`
`(1996).
`
`
`
`To ascertain the meaning of claims, courts look to three primary sources: the claims, the
`
`specification, and the prosecution history. Markman, 52 F.3d at 979. The specification must
`
`contain a written description of the invention that enables one of ordinary skill in the art to make
`
`and use the invention. Id. A patent’s claims must be read in view of the specification, of which
`
`they are a part. Id. For claim construction purposes, the description may act as a sort of
`
`dictionary, which explains the invention and may define terms used in the claims. Id. “One
`
`purpose for examining the specification is to determine if the patentee has limited the scope of
`
`the claims.” Watts v. XL Sys., Inc., 232 F.3d 877, 882 (Fed. Cir. 2000).
`
`
`
`Nonetheless, it is the function of the claims, not the specification, to set forth the limits of
`
`the patentee’s invention. Otherwise, there would be no need for claims. SRI Int’l v. Matsushita
`
`Elec. Corp., 775 F.2d 1107, 1121 (Fed. Cir. 1985) (en banc). The patentee is free to be his own
`
`lexicographer, but any special definition given to a word must be clearly set forth in the
`
`specification. Intellicall, Inc. v. Phonometrics, Inc., 952 F.2d 1384, 1388 (Fed. Cir. 1992).
`
`Although the specification may indicate that certain embodiments are preferred, particular
`
`embodiments appearing in the specification will not be read into the claims when the claim
`
`language is broader than the embodiments. Electro Med. Sys., S.A. v. Cooper Life Sciences, Inc.,
`
`34 F.3d 1048, 1054 (Fed. Cir. 1994).
`
`
`
`This Court’s claim construction analysis is substantially guided by the Federal Circuit’s
`
`decision in Phillips v. AWH Corporation, 415 F.3d 1303 (Fed. Cir. 2005) (en banc). In Phillips,
`
`the court set forth several guideposts that courts should follow when construing claims. In
`
`particular, the court reiterated that “the claims of a patent define the invention to which the
`
`5
`Patent Owner Content Guard Holdings, Inc. - Exhibit 2001, p. 5
`
`

`
`Case 2:13-cv-01112-JRG Document 459 Filed 03/20/15 Page 6 of 144 PageID #: 24028
`
`patentee is entitled the right to exclude.” 415 F.3d at 1312 (quoting Innova/Pure Water, Inc. v.
`
`Safari Water Filtration Sys., Inc., 381 F.3d 1111, 1115 (Fed. Cir. 2004)). To that end, the words
`
`used in a claim are generally given their ordinary and customary meaning. Id. The ordinary and
`
`customary meaning of a claim term “is the meaning that the term would have to a person of
`
`ordinary skill in the art in question at the time of the invention, i.e., as of the effective filing date
`
`of the patent application.” Id. at 1313. This principle of patent law flows naturally from the
`
`recognition that inventors are usually persons who are skilled in the field of the invention and
`
`that patents are addressed to, and intended to be read by, others skilled in the particular art. Id.
`
`
`
`Despite the importance of claim terms, Phillips made clear that “the person of ordinary
`
`skill in the art is deemed to read the claim term not only in the context of the particular claim in
`
`which the disputed term appears, but in the context of the entire patent, including the
`
`specification.” Id. Although the claims themselves may provide guidance as to the meaning of
`
`particular terms, those terms are part of “a fully integrated written instrument.” Id. at 1315
`
`(quoting Markman, 52 F.3d at 978). Thus, the Phillips court emphasized the specification as
`
`being the primary basis for construing the claims. Id. at 1314-17. As the Supreme Court stated
`
`long ago, “in case of doubt or ambiguity it is proper in all cases to refer back to the descriptive
`
`portions of the specification to aid in solving the doubt or in ascertaining the true intent and
`
`meaning of the language employed in the claims.” Bates v. Coe, 98 U.S. 31, 38 (1878). In
`
`addressing the role of the specification, the Phillips court quoted with approval its earlier
`
`observations from Renishaw PLC v. Marposs Societa’ per Azioni, 158 F.3d 1243, 1250 (Fed.
`
`Cir. 1998):
`
`Ultimately, the interpretation to be given a term can only be determined and
`confirmed with a full understanding of what the inventors actually invented and
`intended to envelop with the claim. The construction that stays true to the claim
`
`6
`Patent Owner Content Guard Holdings, Inc. - Exhibit 2001, p. 6
`
`

`
`Case 2:13-cv-01112-JRG Document 459 Filed 03/20/15 Page 7 of 144 PageID #: 24029
`
`language and most naturally aligns with the patent’s description of the invention
`will be, in the end, the correct construction.
`
`Phillips, 415 F.3d at 1316. Consequently, Phillips emphasized the important role the
`
`specification plays in the claim construction process.
`
`
`
`The prosecution history also continues to play an important role in claim interpretation.
`
`Like the specification, the prosecution history helps to demonstrate how the inventor and the
`
`United States Patent and Trademark Office (“PTO”) understood the patent. Id. at 1317. Because
`
`the file history, however, “represents an ongoing negotiation between the PTO and the
`
`applicant,” it may lack the clarity of the specification and thus be less useful in claim
`
`construction proceedings. Id. Nevertheless, the prosecution history is intrinsic evidence that is
`
`relevant to the determination of how the inventor understood the invention and whether the
`
`inventor limited the invention during prosecution by narrowing the scope of the claims. Id.; see
`
`Microsoft Corp. v. Multi-Tech Sys., Inc., 357 F.3d 1340, 1350 (Fed. Cir. 2004) (noting that “a
`
`patentee’s statements during prosecution, whether relied on by the examiner or not, are relevant
`
`to claim interpretation”).
`
`Phillips rejected any claim construction approach that sacrificed the intrinsic record in
`
`favor of extrinsic evidence, such as dictionary definitions or expert testimony. The en banc court
`
`condemned the suggestion made by Texas Digital Systems, Inc. v. Telegenix, Inc., 308 F.3d 1193
`
`(Fed. Cir. 2002), that a court should discern the ordinary meaning of the claim terms (through
`
`dictionaries or otherwise) before resorting to the specification for certain limited purposes.
`
`Phillips, 415 F.3d at 1319-24. According to Phillips, reliance on dictionary definitions at the
`
`expense of the specification had the effect of “focus[ing] the inquiry on the abstract meaning of
`
`words rather than on the meaning of claim terms within the context of the patent.” Id. at 1321.
`
`7
`Patent Owner Content Guard Holdings, Inc. - Exhibit 2001, p. 7
`
`

`
`Case 2:13-cv-01112-JRG Document 459 Filed 03/20/15 Page 8 of 144 PageID #: 24030
`
`Phillips emphasized that the patent system is based on the proposition that the claims cover only
`
`the invented subject matter. Id.
`
`Phillips does not preclude all uses of dictionaries in claim construction proceedings.
`
`Instead, the court assigned dictionaries a role subordinate to the intrinsic record. In doing so, the
`
`court emphasized that claim construction issues are not resolved by any magic formula. The
`
`court did not impose any particular sequence of steps for a court to follow when it considers
`
`disputed claim language. Id. at 1323-25. Rather, Phillips held that a court must attach the
`
`appropriate weight to the intrinsic sources offered in support of a proposed claim construction,
`
`bearing in mind the general rule that the claims measure the scope of the patent grant.
`
`
`
`In general, prior claim construction proceedings involving the same patents-in-suit are
`
`“entitled to reasoned deference under the broad principals of stare decisis and the goals
`
`articulated by the Supreme Court in Markman, even though stare decisis may not be applicable
`
`per se.” Maurice Mitchell Innovations, LP v. Intel Corp., No. 2:04-CV-450, 2006 WL 1751779,
`
`at *4 (E.D. Tex. June 21, 2006) (Davis, J.); see TQP Development, LLC v. Inuit Inc., No. 2:12-
`
`CV-180, 2014 WL 2810016, at *6 (E.D. Tex. June 20, 2014) (Bryson, J.) (“[P]revious claim
`
`constructions in cases involving the same patent are entitled to substantial weight, and the Court
`
`has determined that it will not depart from those constructions absent a strong reason for doing
`
`so.”); see also Teva Pharm. USA, Inc. v. Sandoz, Inc., 135 S. Ct. 831, 839-40 (2015) (“prior
`
`cases will sometimes be binding because of issue preclusion and sometimes will serve as
`
`persuasive authority”) (citation omitted).
`
`
`
`The Court nonetheless conducts an independent evaluation during claim construction
`
`proceedings. See, e.g., Texas Instruments, Inc. v. Linear Techs. Corp., 182 F. Supp. 2d 580,
`
`589-90 (E.D. Tex. 2002); Burns, Morris & Stewart Ltd. P’ship v. Masonite Int’l Corp., 401 F.

`
`(Dkt. No. 292, 11/17/2014 Joint Claim Construction and Prehearing Statement, at 2; see Dkt.
`
`No. 366, Ex. B, 1/23/2015 Joint Claim Construction Chart.)
`
`IV. CONSTRUCTION OF DISPUTED TERMS IN THE STEFIK PATENTS
`
`
`
`The earliest issued of the Stefik Patents is the ‘859 Patent. The ‘859 Patent is titled
`
`“Content Rendering Repository” and issued on November 8, 2005. The Abstract states:
`
`A rendering system adapted for use in a system for managing use of content and
`operative to rendering [sic] content in accordance with usage rights associated
`with the content. The system includes a rendering device configured to render the
`content and a repository coupled to the rendering device and operative to enforce
`usage rights associated with the content and permit the rendering device to render
`the content in accordance with a manner of use specified by the usage rights.
`
`
`
`Four of the six Stefik Patents have been the subject of Inter Partes Review (“IPR”)
`
`proceedings at the PTO’s Patent Trial and Appeal Board (“PTAB”). (See Dkt. No. 331,
`
`Exs. 1-4).
`
`
`
`The Stefik Patents all claim priority to an application filed on November 23, 1994.
`
`Defendants submit that the specifications of the Stefik Patents are “largely identical” except that,
`
`Defendants argue, “the ‘160 patent specification is critically different from the other Stefik
`
`specifications,” as discussed further below. (Dkt. No. 331, at 1 n.1.)
`
`
`
`The present Memorandum Opinion and Order cites only the specification of the ‘859
`
`Patent unless otherwise indicated.
`
`A. “repository” and “trusted”
`
`“repository”
`
`Plaintiff’s Proposed Construction
`
`Defendants’ Proposed Construction
`
`“a trusted system in that it maintains physical,
`communications, and behavioral integrity in
`the support of usage rights”
`
`“a trusted system, which maintains physical,
`communications and behavioral integrity, and
`supports usage rights”
`

`Patent Owner Content Guard Holdings, Inc. - Exhibit 2001, p. 10
`
`

`
`Case 2:13-cv-01112-JRG Document 459 Filed 03/20/15 Page 11 of 144 PageID #: 24033
`
`“trusted”
`
`Plaintiff’s Proposed Construction
`
`Defendants’ Proposed Construction
`
`“maintains physical, communications, and
`behavioral integrity in the support of usage
`rights”
`
`“maintains physical, communications and
`behavioral integrity”
`
`(Dkt. No. 304, at 1; Dkt. No. 331, at 2.) The parties submit that “repository” appears in Claims
`
`1, 15, 21, 24, 58, 71, and 81 of the ‘859 Patent, Claims 1 and 18 of the ‘576 Patent, and Claims 1
`
`and 10 of the ‘072 Patent. (Dkt. No. 292-1, at 7; Dkt. No. 331, at 2.) The parties submit that
`
`“trusted” appears in Claims 1, 7, and 13 of the ‘956 Patent and Claims 1, 6, and 11 of the ‘007
`
`Patent. (Dkt. No. 292-1, at 8; Dkt. No. 331, at 2.)
`
`
`
`
`
`(1) The Parties’ Positions
`
`Plaintiff argues that its proposed construction for “repository” “adopts th[e] language
`
`from the [specification’s] glossary verbatim while Defendants’ proposed construction introduces
`
`ambiguities by replacing ‘in that it’ with ‘which’” and “by replacing ‘in the support of usage
`
`rights’ with ‘and supports usage rights.’” (Dkt. No. 304, at 2.) Plaintiff submits that although
`
`Defendants rely on the construction by the PTAB during an IPR, “[t]he PTAB based its
`
`construction on the same glossary definition [Plaintiff] relies on, but provided no reason to
`
`depart from the language from the glossary.” (Id.)
`
`
`
`Defendants respond that “Defendants’ proposed construction of ‘repository’ follows the
`
`PTAB’s construction verbatim; and Defendants’ construction of the related term ‘trusted,’ which
`
`the PTAB did not construe, mirrors this construction.” (Dkt. No. 331, at 2 (citing, id., Ex. 2,
`
`at 8).) Defendants submit that Plaintiff “actually rearranged pieces of the [specification
`
`glossary’s] definition to alter the meaning of ‘repository.’” (Dkt. No. 331, at 3.) Defendants

`
`explain that “[u]nder [Plaintiff’s] construction, instead of the three integrities being required at
`
`all times, as taught by the Stefik patents and required by the PTAB’s construction, the three
`
`integrities only need to be present when supporting usage rights.” (Id.)
`
`
`
`In an additional, separate responsive brief, Defendant Amazon argues that because the
`
`specification defines “repository” and “trusted” in “purely functional language,” those terms are
`
`indefinite. (Dkt. No. 336, at 3.) Defendant Amazon cites Halliburton Energy Services, Inc. v.
`
`M-I LLC, 514 F.3d 1244 (Fed. Cir. 2008), which found indefinite the term “fragile gel.” (See id.,
`
`at 3-5.)
`
`
`
`Plaintiff replies that Defendants’ argument that a repository must “maintain the three
`
`integrities at all times” “is not found in the PTAB construction and directly contradicts the Stefik
`
`patents’ specification . . . .” (Dkt. No. 345, at 1.) Plaintiff concludes that “[t]here is simply no
`
`basis for defining ‘repository’ as something that maintains the three integrities at all times, even
`
`while conducting transactions that do not support usage rights.” (Id.)
`
`
`
`Plaintiff also replies, as to Amazon’s separate brief, that “Amazon’s arguments should be
`
`rejected because they reflect an elementary misunderstanding of the applicable law and are not
`
`supported by any evidence.” (Dkt. No. 344, at 1.) Plaintiff notes that Amazon submits no expert
`
`opinions on this issue, and Plaintiff submits that “there is ample support in the specification that
`
`describes the boundaries of the three integrities that define [Mr.] Stefik’s concept of ‘trust.’”
`
`(Id., at 3-5 (citing 11:62-12:50).)
`
`
`
`In sur-reply, Defendants argue that, “[l]ogically, [Mr.] Stefik must have intended for
`
`repositories and trusted systems to require the three integrities at all times, otherwise his
`
`inventions would not solve the digital piracy problem.” (Dkt. No. 353, at 1.) Defendants also
`
`note that a “restoration file,” which is used to restore a back-up file, “would be held in [a]

`
`repository,” and “[i]f a repository cannot verify that it is communicating with another trusted
`
`repository, then ‘the registration transaction terminates in an error.’” (Id., at 3 (citing ‘859 Patent
`
`at 27:3-5 & 36:57-58).)
`
`
`
`At the February 6, 2015 hearing, Defendants reiterated that “in support of” is broader
`
`than how the PTAB construed the term and injects ambiguity into the claims.
`
`
`
`
`
`(2) Analysis
`
`The parties disagree as to whether the disputed terms refer to supporting usage rights or
`
`merely being “in the support of usage rights,” as well as whether the three “integrities” must be
`
`present at all times.
`
`
`
`On one hand, the PTAB construed “repository” to mean “a trusted system which
`
`maintains physical, communications and behavioral integrity, and supports usage rights.” (Dkt.
`
`No. 304, Ex. J, 6/26/2014 Final Written Decision, at 10-11.). This prior construction is entitled
`
`to some deference. See Maurice Mitchell, 2006 WL 1751779, at *4; see also TQP, 2014 WL
`
`2810016, at *6; Teva, 135 S. Ct. at 839-40.
`
`
`
`On the other hand, the “Glossary” section of the specification explicitly states:
`
`Repository:
`
`Conceptually a set of functional specifications defining core functionality in the
`support of usage rights. A repository is a trusted system in that it maintains
`physical, communications and behavioral integrity.
`
`‘859 Patent at 50:47-51.
`
`
`
`On balance, the Court finds that by setting forth an explicit definition in a “Glossary,” the
`
`patentee acted as lexicographer and expressly defined the term “repository.” See Intellicall, 952
`
`F.2d at 1388; see also C.R. Bard, Inc. v. U.S. Surgical Corp., 388 F.3d 858, 862 (Fed. Cir. 2004)
`
`(“[T]he inventor’s written description of the invention . . . is relevant and controlling insofar as it

`
`provides clear lexicography . . . .”); Abbott Labs. v. Syntron Bioresearch, Inc., 334 F.3d 1343,
`
`1354 (Fed. Cir. 2003) (“patentee’s lexicography must, of course, appear with reasonable clarity,
`
`deliberateness, and precision”) (citation and internal quotation marks omitted).
`
`
`
`This lexicography finding is supported by other disclosures in the specification, such as
`
`the discussion of “Repositories”:
`
`Repositories
`
`Many of the powerful functions of repositories—such as their ability to “loan”
`digital works or automatically handle the commercial reuse of digital works—are
`possible because they are trusted systems. The systems are trusted because they
`are able to take responsibility for fairly and reliably carrying out the commercial
`transactions. That the systems can be responsible (“able to respond”) is
`fundamentally an issue of integrity. The integrity of repositories has three parts:
`physical integrity, communications integrity, and behavioral integrity.
`
`‘859 Patent at 11:51-61; see also 6:29-31 (“the digital work genie only moves from one trusted
`
`bottle (repository) to another”). The specification also discloses that a repository may
`
`communicate with a non-repository and that not all communications between repositories are
`
`secure. See id. at 25:37-52, 26:30-67 (“registration transaction”) & 37:12-21 (“non-repository
`
`archive storage”).
`
`
`
`To whatever extent Defendant Amazon maintains that Plaintiff’s construction is
`
`improperly functional rather than structural, that argument is rejected. See, e.g., Hill-Rom Servs.,
`
`Inc. v. Stryker Corp., 755 F.3d 1367, 1374-75 (Fed. Cir. 2014) (“defining a particular claim term
`
`by its function is not improper”); Funai Elec. Co. v. Daewoo Elecs. Corp., 616 F.3d 1357, 1366
`
`(Fed. Cir. 2010) (“The use of comparative and functional language to construe and explain a
`
`claim term is not improper. A description of what a component does may add clarity and
`
`understanding to the meaning and scope of the claim.”); Microprocessor
