`
`III. OVERVIEW OF THE ’246 PATENT
`
`A.
`
`Summary of the Claimed Subject Matter
`
`The ’246 Patent “relates to the secure distribution of digitized value-added
`
`information, or media content ...” Ex[1003] 1:48-49.
`
`The system of the ’246 Patent includes a local content server (“LCS”) for
`
`storing content, authentication of content, enforcement of export rules and
`
`watermarking. Id. 11:40-42. FIG. 1 illustrates a sample LCS system:
`
`’246 Patent, Ex[1003] FIG. 1.
`
`
`
`4
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`The LCS includes an LCS domain, a logical area inside which a rule system is
`
`enforced for transfer of digital content in and out of the LCS domain. Id. 10:19-26.
`
`The system may include a Satellite Unit (SU), a portable device that can accept
`
`digital content from an LCS and that can play or make playable the content. Id.
`
`7:63-66, FIG. 1.
`
`One feature of the system is a level of security for high-quality content while
`
`providing unsecured content at a degraded quality level. Id. 10:62-64. FIG. 2
`
`reproduced below illustrates that content that can be validated (e.g., by a watermark)
`
`can enter the LCS domain, content that can be validated but belongs to a different
`
`LCS domain is excluded, and unvalidatable content will enter subject to quality
`
`degradation. Id. 10:39-46, 10:62-11:9. If a watermark is absent, the LCS may
`
`read the content as “legacy” content. Id. 17:17-19.
`

`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`’246 Patent, Ex[1003] FIG. 2
`
`B.
`
`Prosecution History of the ’246 Patent
`
`
`
`The application issuing as the ’246 Patent was filed July 23, 2002 as U.S.
`
`Patent Application No. 10/049,101 (the “101 Application”), a U.S. National Stage
`
`Entry of PCT Application No. PCT/US00/21189, filed August 4, 2000. The ’101
`
`Application and the ’246 Patent claim priority to U.S. Provisional Application Nos.
`
`60/147,134 (the ’134 Provisional) filed August 4, 1999, Ex[1013], and 60/213,489
`
`(the ’489 Provisional) filed June 23, 2000, Ex[1012].
`
`During prosecution of the ’101 Application, Applicant amended the claims to
`
`recite “if the digital content is not authorized for use by the LCS, accepting the digital
`
`content at a predetermined quality level, said predetermined quality level having
`
`6
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`been set for legacy content.” Ex[1010] 189-201. In response to a rejection,
`
`Applicant argued that the prior art fails to disclose how to identify, differentiate, or
`
`authorize legacy content—e.g., material already possessed by users. The Examiner
`
`allowed the claims, purportedly because the prior art lacked the element “and if the
`
`digital content is not authorized for use by the LCS, accepting the digital content at
`
`a predetermined quality level, said predetermined quality level having been set for
`
`legacy content.” Ex[1010] 2499.
`
`C.
`
`Priority
`
`The earliest claimed priority date for the ’246 Patent is August 4, 1999 based
`
`on the filing date of the ‘134 Provisional. At least claim 1 of the ’246 Patent is
`
`entitled to a priority date of no earlier than August 4, 2000, because that claim
`
`includes at least one limitation directed to subject matter not disclosed in the ’134
`
`and ’489 Provisionals.
`
`The ’101 Application added significant subject matter not disclosed in
`
`the ’134 and ’489 Provisionals. Exhibits 1025 and 1026 are comparisons between
`
`the ’101 Application and the ’489 and ‘134 Provisionals, respectively. New
`
`portions are double underlined and deletions are struck-through. The comparison
`
`shows that claim 1 recites at least one element disclosed no earlier than the ’101
`
`Application. For example, there is no disclosure of an “LCS communications port,”
`
`and “programmable address module,” which are elements of claim 1. See, e.g.,
`
`Ex[1025] 3; Ex[1026] 2.
`
`7
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`Petitioner’s expert agrees that claim 1 is entitled to a priority date no earlier
`
`than August 4, 2000, and that claims 20, 21, 24, and 25 are entitled to a priority date
`
`no earlier than August 4, 1999. Ex[1006] ¶¶52-56.
`
`IV. SUMMARY OF PRIOR ART AND REFERENCES RELIED ON
`
`As Dr. Chatterjee explains, the Digital Rights Management (DRM) concepts
`
`claimed in the ’246 Patent were well-known in the prior art. Ex[1006] ¶¶28-44.
`
`By the earliest claimed priority date of the ’246 Patent, numerous electronic
`
`companies had developed systems that protected audio and video content against
`
`unauthorized copying, use, and distribution. Id. ¶40. “These systems applied
`
`various combinations of familiar encryption and watermarking techniques to the
`
`now rapidly growing field of electronic commerce.” Id. In 1998, over 100
`
`consumer and electronic companies formed the Secure Digital Music Initiative
`
`(SDMI) to consider the advantages of encryption and watermarking digital content
`
`protection techniques already in existence and agree on a common standard. Id.
`
`¶42. Therefore, by the earliest filing date cited in the ’246 Patent, combinations of
`
`encryption and watermarking for DRM were well-developed and had matured to a
`
`standard.
`
`Dr. Chatterjee explains that systems that made a plurality of versions of
`
`content available to a user were well-known prior to the alleged invention of the ’246
`
`Patent. Id. ¶44. U.S. Patent No. 6,128,148 to Platte, et. al. (“Platte”) discloses a
`
`8
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`videocassette system capable of playing back both high-definition (HD) video or
`
`standard definition (SD) video based on authorizations. Platte explains:
`
`In order to reduce the risk of theft for such cassettes, a special entry
`may be necessary at the position provided for the usage authorization
`so that the playback function of the reproduction device is released at
`all…. Not only is it possible to generally authorize the playback of a
`cassette by means of an appropriate entry[;] [f]urthermore, just
`certain functions can be authorized for the playback. With compatible
`HDTV/TV recordings, it is, for example, possible to just permit the TV
`playback with lower resolution; for recordings with stereo sound and
`surround sound, the playback of the surround sound can be blocked.
`Further, it is also possible to design a memory position within the
`memory device as a counter for the number of playbacks permitted.
`Ex[1028] 3:54-4:10. Therefore, providing HD or SD video based on user
`
`authorizations was well-known by the time of the alleged invention of the ’246
`
`Patent. Ex[1006] ¶44.
`
`Prior art references Yeung, Lee, and Downs illustrate that the ’246 Patent
`
`claims what was well-known in the prior art. This Petition does not present “the
`
`same or substantially the same prior art or arguments previously [] presented to the
`
`Office” and the Board should not deny institution under 35 U.S.C. §325(d) for the
`
`following reasons. See Becton, Dickinson & Co. v. Braun Melsungen AG,
`
`IPR203101586, slip op. at 16-18 (Paper 8) (PTAB Dec. 15, 2017) (informative).
`
`First, although the Applicant cited Yeung in an Information Disclosure
`
`Statement during the prosecution of the ’246 Patent, it was listed together with over
`
`9
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`300 references, and was not substantively evaluated with respect to the ’246 Patent
`
`claims and is therefore not cumulative. Ex[1010] 16-18, 177.
`
`Second, expert testimony (Ex[1006]) has been submitted with this Petition,
`
`which was not available to the Examiner, explaining how a POSA would understand
`
`Yeung, Lee, and Downs and how and why a POSA would combine them.
`
`Therefore, this Petition presents additional evidence and facts that are not cumulative
`
`of the arguments considered during ex parte persecution. Becton, Dickinson,
`
`IPR2017-01586, at 17-18.
`
`Finally, there are material differences between these references and the prior
`
`art involved during examination: U.S. Patent No. 6,522,769 to Rhoads et al. (“’769
`
`Patent”), U.S. Patent No. 6,493,457 to Quackenbush et al. (“’457 Patent”), U.S.
`
`Patent No. 5,341,429 to Stringer et al. (“Stringer”) and U.S. Patent No. 6,148,333 to
`
`Guedalia et al. (“Guedalia”). See, e.g., Ex[1010] 149-175. The ’769 Patent is
`
`directed to reconfiguring a watermark detector and the ’457 Patent is directed to
`
`insertion of an imperceptible watermark in the compressed domain that can be
`
`detected without a reference. Id. 206-207. Stringer is directed to transforming
`
`trial versions of digital materials to their original form upon purchase and Guedalia
`
`is directed to monitoring user access to a shared image server. Id. 318-325. As
`
`shown below, Yeung, Lee, and Downs focus on the use of encryption and/or
`
`10
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`watermarking to control content access and use during digital content distribution.
`
`Thus, these references are materially different than those applied during prosecution.
`
`A.
`
`Brief Summary of Yeung (Ex[1014])
`
`Yeung is entitled “Multimedia data delivery and playback system with
`
`multi-level content and privacy protection.”
`
` Yeung teaches a three-tier
`
`architecture for the secure distribution and storage of digital content, a server
`
`platform 110, a client platform 120, and a content player 450. Ex[1014] 7:34-62,
`
`2:29-33.
`
`FIG. 1 illustrates the relationship between the server platform 110, the client
`
`platform 120, and the transfer of content 160 between the platforms.

`
`
`
`Yeung, Ex[1014] FIG. 4
`Yeung’s client platform distributes and protects content through the
`
`implementation of “content protection mechanisms,”
`
`including watermark
`
`extraction 440 and watermark insertion 280. Ex[1014] 1:53-54, FIG. 4. The
`
`descrambling mechanisms 420 and 430 determine whether the client platform 120
`
`provides “lesser quality content” to the content player 450 or “full-quality content.”

`
`Brief Summary of Lee (Ex[1017])
`
`Lee is entitled “Copy Protection System for Portable Storage Media” and is
`
`“generally related to encryption processes and apparatus.” Ex[1017] 1:16-17.
`
`Lee explains “[T]here is a need for a technique to preserve transmission security of
`
`12
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`revenue bearing information while restricting access to the information by
`
`unauthorized entities ….” Ex[1017] 1:4-6.
`
`To address this need, Lee discloses an “encryption processes and apparatus”
`
`with three main components: (1) an internet service provider (ISP) 130 as a content
`
`supplier, (2) a licensed SDMI (secure digital music initiative) compliant module
`
`(LCM) 140 as a first content output unit, and (3) a portable device (PD) 150 as a
`
`second content output unit. See, e.g., Ex[1017] FIG. 1. The encryption processes
`
`and apparatus “employ user information in the generation and use of multiple
`
`cryptographic keys during the transmission of digital content to the user.” Ex[1017]
`
`2:53-56. It also “provid[es] copy protection during downloading and during
`
`uploading of the digital contents.” Ex[1017] 3:37-38. FIG. 1 illustrates the
`
`architecture and the flow of content between the ISP, LCM, and PD:

`
`Brief Summary of Downs (Ex[1030])
`
`Downs is entitled “Electronic content delivery system” and is related to “a
`
`method and apparatus of securely providing data to a user’s system.” Ex[1030]
`
`Abstract. Downs' system “is a technical platform that encompasses the technology,
`
`16
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`specifications, tools, and software needed for the secure delivery and rights
`
`management of Digital Content and digital content-related content to an end-user,
`
`client device.” Ex[1030] 6:37-43. Downs’ “End-User Devices” include PCs, set
`
`top boxes (IRDs), and Internet appliances. Id. Upon receiving content, “the End-
`
`User Device(s) 109 watermarks the copy of the Content 113 with the content
`
`purchaser’s name and the Transaction ID 535 … and with other information such as
`
`date of license and Usage Conditions 517.” Id. 22:15-24.
`
`V. CLAIM CONSTRUCTION
`
`Under 37 CFR §42.100, claims should be construed “using the same claim
`
`construction standard that would be used to construe the claim in a civil action under
`
`35 U.S.C. 282(b)” (the “Phillips standard”).2
`
`A. Level of Ordinary Skill in the Art
`A person of ordinary skill in the art (“POSA”) would have a bachelor’s degree
`
`in computer science, and at least two to three years of experience related to secure
`
`distribution of digitized information or a related technology field, such as data
`
`integrity and security. Ex[1006] ¶¶107-109.
`
`B.
`
`“local content server system (LCS)” or “Local Content Server (LCS)”
`(Claims 1, 20, 24)
`“Local Content Server (LCS)” is expressly defined by the patentee as:
`
`
`2 Petitioner reserves the right to seek different claim constructions in the District
`Court Action.
`
`17
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`A device or software application which can securely store a collection
`of value-added digital content. The LCS has a unique ID.
`Ex[1003] 7:51-53.
`“Value-added” is further defined:
`
`Value-added information is differentiated from non-commoditized
`information in terms of its marketability or demand, which can vary,
`obviously, from each market that is created for the information. By
`way of example, information in the abstract has no value until a market
`is created for the information (i.e., the information becomes a
`commodity). The same information can be packaged in many
`different forms, each of which may have different values. Because
`information is easily digitized, one way to package the “same”
`information differently is by different levels of fidelity and discreteness.
`Value is typically bounded by context and consideration.
`Ex[1003] 9:1-12.
`
`A POSA would not find that the “value-added digital content” portion of the
`
`LCS definition is patentably distinct (i.e., there is no structural difference between a
`
`system storing value-less digital information versus one storing value-added digital
`
`information). Ex[1006] ¶116. However, the patentee explicitly defined “value-
`
`added” as content for which a market exists, thus a POSA would understand “value-
`
`added digital content” in the definition of “local content server (LCS)” to mean
`
`“digital content for which there is any demand.”
`
`The ’246 Patent describes the “local content server system (LCS)” as
`
`“creating a secure environment for digital content,” and further describes “a content
`
`data set that is stored on the LCS.” Ex[1003] 2:24-25, 3:1-3.
`
`Therefore, a POSA would understand “LCS” to mean “a device or software
`
`18
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`application which can securely store a collection of value-added digital content,
`
`where value-added digital content is digital content for which there is any demand.”
`
`Ex[1006] ¶120.
`
`C.
`“Secure Electronic Content Distributor (SECD)” (Claim 1)
`The “DEFINITIONS” section defines “Secure Electronic Content
`
`Distributor”:
`
`An entity, device or software application which can validate a
`transaction with a LCS, process a payment, and deliver digital content
`securely to a LCS.
`Ex[1003] 7:54-57.
`The Summary of the Invention explains:
`
`[The] SECD is capable of storing a plurality of data sets, is capable of
`receiving a request to transfer at least one content data set, and is
`capable of transmitting the at least one content data set in a secured
`transmission.
`Ex[1003] 7:28-32. This is consistent with the patentee’s explicit definition of
`
`“Secure Electronic Content Distributor.”
`
`Therefore, a POSA would understand that “Secure Electronic Content
`
`Distributor (SECD)” means “an entity, device or software application which can
`
`validate a transaction with a LCS, process a payment, and deliver digital content
`
`securely to a LCS.” Ex[1006] ¶¶121-124.
`
`D.
`“content” (Claims 1, 20, 21, 24, and 25)
`The term “content” appears in claims 1, 20, 21, 24, and 25, in some cases
`
`multiple times within a claim.
`
`19
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`The DEFINITIONS section defines “content” to “refer generally to digital
`
`data, and may comprise video, audio, or any other data that is stored in a digital
`
`format.” Ex[1003] 7:60-62. Numerous other phrases are defined in terms of their
`
`interaction with “content” or “digital content” See Ex[1003] 7:51-8:12, 8:28-49
`
`(defining, e.g., “Local Content Server” and “Secure Electronic Content Distributor”).
`
`The Background of the Invention states “a need exists for a new and improved
`
`system for protecting digital content against unauthorized copying and distribution.”
`
`Ex[1003] 2:18-20. The LCS is described as “creating a secure environment for
`
`digital content.” Ex[1003] 2:24-25, 2:51-52. These descriptions are consistent
`
`with the patentee’s explicit definition of “content.”
`
`Thus, a POSA would understand the term “content” to mean “data in digital
`
`format.” Ex[1006] ¶¶125-129.
`
`E.
`“predetermined quality level” (Claims 1, 20, and 24)
`Independent claim 1 recites accepting digital content under certain conditions
`
`at “a predetermined quality level.” Ex[1003] 19:30-54. Independent claims 20
`
`and 24 refer to “delivering the content data set … at a predetermined quality level”
`
`and “delivering the watermarked content data set … at a predetermined quality
`
`level,” respectively. Ex[1003] 24:12-33, 24:26-67.
`
`While the patentee defines the terms “Standard Quality,” “Low Quality,” and
`
`“High Quality,” none of these definitions address the term under construction:
`
`“predetermined quality level.” Thus, a POSA would understand the term
`
`20
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`“predetermined quality level” to have its plain and ordinary meaning. Ex[1006]
`
`¶¶130-133.
`
`F. “open watermark” (Claim 21) and “robust open watermark” (Claim
`25)
`Claim 21 refers to “embedding an open watermark into [] content data.” A
`
`POSA would understand “open watermark” to mean “a watermark readable by
`
`multiple devices.” This understanding is consistent with how the term “open
`
`watermark” is used in the ’246 Patent. The Detailed Description of The Invention
`
`refers to “open watermark” as a “watermark that relies on a secret which is shared
`
`by an entire class of devices, as opposed to a secure watermark—which is readable
`
`only by a single member of a class of devices.” Ex[1003] 16:64-17:3. A POSA
`
`would understand “entire class of devices” to mean multiple devices. Ex[1006]
`
`¶137. A POSA would understand the “secret” shared by the devices as multiple
`
`devices being aware of how to access the watermark. Id. Thus, a POSA would
`
`understand the term “open watermark” to mean “a watermark readable by multiple
`
`devices.” Ex[1006] ¶138.
`
`A POSA would understand “robust open watermark” to mean “a watermark
`
`that can withstand encryption or decryption and that is readable by multiple devices.”
`
`A POSA would understand a “robust watermark” to be a watermark that can
`
`withstand manipulation of the watermarked content (e.g., encryption or decryption),
`
`as opposed to a fragile watermark that is affected by manipulation of the
`
`21
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 7,475,246
`
`watermarked content. Ex[1006] ¶¶140-141. This is consistent with how the term
`
`robust watermark is used in the ’246 Pate
