`U.S. Patent No. 10,972,584
`Petition for Inter Partes Review – IPR2022-01554
`
`
`INTRODUCTION
`
`Petitioner respectfully requests inter partes review (“IPR”) of Claims 17-21,
`
`I.
`
`
`
`25-35, 54-57, 59-69, 85-89, 93-99 (“Challenged Claims”) of U.S. Patent No.
`
`10,972,584 (EX1301, “’584 Patent”). The Board should institute trial and cancel
`
`the Challenged Claims.
`
`The Challenged Claims purport to cover the basic idea of a “portable device”
`
`with a memory and processor such that the portable device can communicate with a
`
`network and a “terminal.” But this architecture was well known before the ’584
`
`Patent: both in general and specifically in the personal digital assistant (“PDA”) art.
`
`PDA prior art never considered by the Patent Office renders the Challenged Claims
`
`unpatentable. The Patent Owner’s infringement theories against Petitioner’s
`
`products in co-pending district court litigation confirm the overbreadth of the
`
`Challenged Claims and that the asserted prior art reads on the same.
`
`II. MANDATORY NOTICES
`A. Real Party-In-Interest (37 C.F.R. § 42.8(b)(1))
`
`The petitioner in this proceeding is Roku, Inc. (“Roku” or “Petitioner”) and
`
`Roku is the real party-in-interest. There are no other real parties-in-interest.

`
`
`
`Discretionary Denial is Not Warranted
`
`Petitioner respectfully submits that the Board should not exercise its
`
`discretion under 35 U.S.C. §§314(a) or 325(d) to deny this Petition.
`
`(a) The Fintiv factors do not apply
`
`Denial would be improper based on Apple Inc. v. Fintiv, Inc., IPR2020-0019,
`
`Paper 11 (PTAB Mar. 20, 2020) because the Petition presents compelling evidence
`
`of unpatentability. Interim Procedure For Discretionary Denials in AIA Post-Grant
`
`Proceedings With Parallel District Court Litigation, at 3-4 (Jun. 21, 2022).
`
`(b) The General Plastic factors do not apply
`
`The ’584 Patent has not been challenged in any prior IPR petition. As such,
`
`none of the discretionary factors in General Plastic Indus. Co., Ltd. v. Canon
`
`Kabsuhiki Kaisha, IPR2016-01357, Paper 19 at 16 (PTAB Sep., 6, 2016) (Section
`
`II.B.4.i precedential) apply to this Petition, and discretionary denial is not warranted.

`
`
`(c) The Becton, Dickinson factors favor institution
`
`None of the asserted references or Dr. Lippman’s testimony were disclosed,
`
`cited, or considered during prosecution. As such, the discretionary factors in Becton,
`
`Dickinson & Co. v. B. Braun Melsugen AG, IPR2017-01586 Paper 8 (PTAB Dec.
`
`15, 2017) (precedential) weigh in favor of institution, and discretionary denial is not
`
`warranted.
`
`The asserted references are materially different from the prior art considered
`
`by the Examiner; and are not cumulative of the art actually relied upon during
`
`prosecution. As discussed below, the Examiner never rejected the Challenged
`
`Claims and noted in reasons for allowance that the art of record did not teach certain
`
`features. But the asserted references teach the features that the Examiner found
`
`lacking in the art of record. For at least this reason, Alger is materially different and
`
`not cumulative of the art of record.
`
`V. BACKGROUND
`A.
`
`’584 Patent
`
`The ’584 Patent discloses “a portable device [referred to throughout the
`
`specification as a tunneling client access point (“TCAP”)] configured to
`
`communicate with a terminal and a network server, and execute stored program code
`
`7
`
`
`
`
`
`

`

`U.S. Patent No. 10,972,584
`Petition for Inter Partes Review – IPR2022-01554
`
`in response to user interaction with an interactive user interface.” EX1301, Abstract.
`
`Figure 1, below, illustrates a topology of a TCAP connected to a terminal (right side
`
`of figure) and back-end TCAP server(s) (left side of figure). Id. 3:59-60.
`
`The topology includes remote storage 105; servers 110, 115, and 120;
`
`communication network 113a, 113b, and 113c; access terminals (“ATs”) 127; TCAP
`
`
`
`130; and user 133a. Id. 3:59-4:4, 4:17-40.
`
`B.
`
`Prosecution History of the ’584 Patent
`
`The ’584 Patent issued from a sixth continuation application, U.S. Application
`
`No. 16/579,169 (the “’169 Application”). The Challenged Claims were never
`
`rejected by the Examiner in an Office Action during examination. Further, many of
`
`8
`
`
`
`
`
`

`

`U.S. Patent No. 10,972,584
`Petition for Inter Partes Review – IPR2022-01554
`
`the Challenged Claims were added or amended after the Notice of Allowance.
`
`Lippman, ¶53; EX1302, pp.26-41, 44-52.
`
`The Examiner stated that the art of record does not teach “the portable device
`
`comprising a communication interface, network interface, an interactive user
`
`interface and program code that receives commands and affect presentation on the
`
`interactive user interface” and “other features such as the portable device configured
`
`to facilitate key exchange as well as securely transmitting the processed data through
`
`the communication interface.” EX1302, pp.49-50; Lippman, ¶55.
`
`C. Overview of Technology and Asserted Prior Art
`
`
`
`Overview of Technology
`
`The architecture recited in the Challenged Claims was well known before the
`
`priority date of the ’584 Patent. Lippman, ¶69.
`
`A Pocket PC is a computing device “that can rest on your hand and fit in your
`
`pocket.” PocketPC Guide, p.27. Pocket PCs utilize the Windows CE operating
`
`system, “can connect to the Internet,” and can be used to “send and receive e-mail,
`
`browse [and download] any Web site, transfer files,” “read books, and listen to
`
`music,” and “play video.” PocketPC Guide, pp.21, 27, 322, 323; Lippman, ¶70.

`
`
`
`
`
`

`

`U.S. Patent No. 10,972,584
`Petition for Inter Partes Review – IPR2022-01554
`
`Windows CE supports “video output to external monitors,” thus allowing the
`
`Pocket PC to display content on a “regular computer monitor.” PocketPC Guide,
`
`pp.33, 331; Lippman, ¶71. Thus, some Pocket PCs included “a port to connect an
`
`external monitor,” and sometimes used “an adapter to connect to monitor cables.”
`
`PocketPC Guide, p.76; Lippman, ¶71.
`
`Secure network communication using encryption and digital certificates, and
`
`secure communication between portable devices and terminals using, for example,
`
`the HDCP protocol, were well known before the priority date of the ’584 Patent, as
`
`illustrated by Ford and HDCP 1.0, respectively. Lippman, ¶¶72-80.
`
`
`
`Overview of Asserted Prior Art
`(a) Alger
`
`Alger teaches a client portal for “reviewing and purchasing electronic books.”
`
`Alger, ¶[0010]; Lippman, ¶¶81-82. The portal may access “available [preselected]
`
`sites” and sites offering “product[s] that the portal is optimized to purchase,” and
`
`may be “part of an application” that “seamlessly retrieves content from a network
`
`and integrates the content into the application.” Alger, ¶[0010]; Lippman, ¶¶82-86.
`
`The system illustrated in FIG. 1 includes a “computing device in the form of”
`
`a “personal digital assistant” (“PDA”) 120. Alger, ¶[0019]; Lippman, ¶87.

`
`
`Alger FIG. 1
`
`
`
`Monitor 147 is connected to PDA 120 via “video adapter 148.” Id. PDA “120
`
`may operate in a networked environment using logical connections to one or more
`
`remote computers,” such as “remote computer 149.” Alger, ¶[0022]; Lippman, ¶89.
`
`Client portal 301 shown in FIG. 3 includes “operating functions 302” and
`
`“memory 303” and “provides access to obtain and convey information over a
`
`network such as the Internet.” Alger, ¶[0029]; Lippman, ¶¶90-92. Operating

`functions 302 provide “user interfaces” (“UIs”) 304 and 305. Alger, ¶[0029];
`
`Lippman, ¶¶90-92.
`
`Alger FIG. 3.
`
`(b) Lyle
`
`Lyle teaches “content protection using a transmitter that encrypts data, a
`
`receiver that receives and decrypts the encrypted data, and an external agent that
`
`
`

`
`
`
`
`
`

`

`U.S. Patent No. 10,972,584

`
`communicates with” the “transmitter and receiver to facilitate the encryption and
`
`decryption.” Lyle, 1:7-16; Lippman, ¶¶94-96.
`
`A “transition minimized differential signaling interface (‘TMDS’ link)” is
`
`used for “transmission of video data from” a “host processor” (e.g., portable
`
`computer) operating as a transmitter “to a monitor” or other display device operating
`
`as a receiver. Lyle, 1:20-28, 64-67; Lippman, ¶97.
`
`Lyle teaches “encryption and decryption of data in accordance with the” High-
`
`bandwidth Digital Content Protection (“HDCP”) protocol and other protocols, over
`
`“a TMDS serial link” such as DVI. Lyle, 2:3-11, 3:6-11, 7:8-16; Lippman, ¶¶98-99.
`
`An “external agent [can provide keys] to” the “receiver and transmitter.” Lyle,
`
`7:38-62; Lippman, ¶¶100-102.
`
`(c) Halbert
`
`Halbert teaches “secure transactions via an interactive television ‘ticker.’”
`
`Halbert, ¶[0002]; Lippman, ¶¶104-108. FIG. 1 shows “system 100 for distributing
`
`ticker,” “Internet,” and “television content,” including “Internet 102,” “content
`
`sources 104,” “distribution centers” 106, and “client terminals 108.” Halbert,
`
`¶[0026]; Lippman, ¶109. Portals “can be provided for” “cellular telephones” and
`
`“PDAs” to access “system 100.” Halbert, ¶[0033]; Lippman, ¶¶109-110.

`
`
`(d) Dowling
`
`Dowling teaches a retractable keyboard and a display that provide a non-area-
`
`constrained [UI] and allow Dowling’s mobile unit to “function as a laptop/desktop
`
`computer.” Dowling, Abstract, ¶[0006]; Lippman, ¶¶112-114. These devices may
`
`be connected
`
`to Dowling’s mobile unit/smart phone using “Bluetooth™

`
`connections.” Dowling, Abstract; Lippman, ¶114. The mobile unit may be used to
`
`download media from a server and display the media using UIs of the mobile unit.
`
`Dowling, ¶¶[0032], [0038]; Lippman, ¶115.
`
`VI. LEVEL OF ORDINARY SKILL IN THE ART
`
`On or before 3/24/2004, a POSA in the field of the ’584 Patent would have
`
`had a Bachelor of Science degree in Electrical Engineering, Computer Science,
`
`Computer Engineering or related discipline, and experience in programming
`
`software or firmware for computers/peripheral devices or databases/servers, and
`
`would have had a working understanding of computer hardware, operating systems,
`
`encryption, data storage, user interfaces, and communication protocols. Lippman,
`
`¶¶60-64.
`
`
`
`VII. CLAIM CONSTRUCTION
`
`Claims are construed in accordance with the Phillips standard applied in
`
`district court. 37 C.F.R. § 42.200(b). Although the District Court has not yet
`
`construed claims in the District Court Case, Patent Owner has served infringement
`
`contentions showing Patent Owner’s expected interpretations of certain claim terms,
`
`including “terminal” and “facilitate a key exchange” recited in independent Claims
`
`1, 39, and 73. Lippman ¶¶65-66. Patent Owner is expected to take the same positions
`
`15
`
`
`
`
`
`

`

`U.S. Patent No. 10,972,584
`Petition for Inter Partes Review – IPR2022-01554
`
`on “terminal” and “facilitate a key exchange” in this proceeding, and based on these
`
`expected interpretations, the prior art discloses all limitations of the Challenged
`
`Claims.
`
`The table below summarizes Petitioner’s understanding of Patent Owner’s
`
`interpretation of certain terms recited in the Challenged Claims based on Patent
`
`Owner’s infringement contentions:
`
`Claim Term
`
`
`“terminal”
`(Claims 1, 39, and 73)
`
`“facilitate a key exchange”
`(Claims 1, 39, and 73)
`
`
`
`Patent Owner’s Expected
`Interpretation in This Proceeding
`
` A
`
` “computing device,” which is
`broad enough to include a TV or
`monitor that displays video and/or
`outputs audio (See, e.g., EX1310,
`p.160; EX1309, p.72; EX1314, p.9-
`10).
`Broad enough to include initiating
`or participating in a key exchange
`(See, e.g., EX1310, pp.162-166;
`EX1309, p.74).
`
` Petitioner submits that the other terms recited in the Challenged Claims, other
`
`than those identified in the table above, can be given their ordinary and customary
`
`meaning as would have been understood by a POSA. Thus, no express constructions
`
`are needed for the Board to institute the IPR and cancel the Challenged Claims.

`VIII. GROUNDS OF UNPATENTABILITY
`A. Ground 1: Combining Alger and Lyle Renders Claims 17-21, 25-
`26, 29-35, 54-57, 59-60, 63-69, 85-89, 93-94, and 97-98 Obvious
`
` Motivation to Combine Alger and Lyle
`
`A POSA would have been motivated to combine Alger and Lyle to arrive at
`
`the alleged invention of Claims 17-21, 25-26, 29-35, 54-57, 59-60, 63-69, 85-89, 93-
`
`94, and 97-98 and would have had a reasonable expectation of successfully doing
`
`so. Lippman, ¶¶122-123.
`
`Alger and Lyle each teach delivering electronic media from a server to a
`
`computer, and, in turn, to a display connected to the computer. Id. ¶124.
`
`Alger’s system includes a computing device (i.e., PDA 120) connected to
`
`remote computer(s) (i.e., remote computer 149) over a network. Alger, ¶¶[0019],
`
`[0022], FIG. 1; Lippman, ¶¶125-126.

`
`
`Alger FIG. 1.
`
`
`
`System bus 123 “couples various system components” to “processing unit
`
`121” of PDA 120, and “monitor 147” is “connected to the system bus 123” via
`
`“video adapter 148.” Alger, ¶¶[0019], [0021], FIG. 1; Lippman, ¶127.
`
`Client portal 301 “can be used with a media player application for playing
`
`back electronic media,” and can be employed to list “Web sites that offer electronic
`
`media, and then to retrieve content from these sites directly into the media player.”
`
`Alger, ¶[0049]; Lippman, ¶128.

`
`“[C]ontent preferred by a user” may be downloaded “to the client portal 301”
`
`but may be inaccessible “until the user actually purchases the content.” Alger,
`
`¶[0068]; Lippman, ¶124. The “downloaded content” may be “encrypted with a key
`
`that is unavailable to the user” until “the user makes an offline request to purchase
`
`the content.” Lippman, ¶129.
`
`Lyle teaches that a TMDS/TMDS-like link is used for “transmission of video
`
`data” from “a host processor” (e.g., a desktop or portable computer) operating as a
`
`transmitter “to a monitor” operating as a receiver. Lyle, 1:20-28, 64-67, 6:9-17;
`
`Lippman, ¶¶130-131.
`
`Lyle teaches “encryption and/or decryption of data in accordance with the
`
`HDCP protocol” and other protocols, for “transmission over a TMDS” link such as
`
`DVI. Lyle, 2:3-11, 3:6-16, 7:8-16; Lippman, ¶¶132-133.
`
`In the system architectures shown in FIGs. 7 and 8, where content transmitted
`
`from a source (i.e., 11 in FIG. 7 and 111 in FIG. 8, either of which could be an audio
`
`or video server) is protected by a hierarchy of protocols. Lyle, 19:4-50; Lippman,
`
`¶¶134-135.

`
`“Content authority 116, content source 111, content router 113, delivery paths
`
`121 and 122, and handshake paths 124, 125, and 126 of FIG. 8 correspond
`
`functionally to content authority 16, content source 11, content router 13, delivery
`
`paths 21 and 22, and handshake paths A, B, and C of FIG. 7.” Lyle, 25:42-47;
`
`Lippman, ¶137. Thus, “units 114 and 115 [of FIG. 8] correspond to a distributed
`
`implementation of receiver 15 of FIG. 7.” Lyle, 25:47-52; Lippman, ¶¶137-140.
`
`“[R]eceiver 15 is the final destination of the encrypted data,” is “configured
`
`to decrypt the encrypted data that it receives,” and “can be a TV set, a portable MP3
`
`21
`
`
`
`
`
`

`

`U.S. Patent No. 10,972,584

`
`player, an information kiosk,” or “another final destination.” Lyle, 19:9-17;
`
`Lippman, ¶134. “[D]elivery path 21 can” be “an internet connection” or a cable
`
`“link, and delivery path 22” is a “TMDS-like link.” Lyle, 19:41-50; Lippman, ¶136.
`
`Advanced Encryption Standard (“AES”) protocol can “encrypt data
`
`transmitted over paths 121 and 122.” Lyle, 26:15-18; Lippman, ¶141. Content source
`
`111 sends encrypted data over path 121 to router 113, which forwards the encrypted
`
`data over path 122 to receiver 114. Lyle, 26:18-25. Receiver 114 uses a
`
`cryptographic key to decrypt the encrypted data, re-encrypts the data, and sends the
`
`re-encrypted data to receiver 115 via link 123.” Id. 26:28-33. Receiver 115 decrypts
`
`the data received over link 123, and displays the decrypted data. Id. 26:37-40; see
`
`also id. 25:53-63, 11:57-63, 12:19-22.
`
`Content authority 116 supplies each of router 113 and receivers 114 and 115
`
`with cryptographic keys, although there “are many [other] ways to perform a key
`
`exchange.” Lyle, 13:20-45, 21:2-6, 22:60-65, 25:39-47, 26:25-28, 33-37; Lippman,
`
`¶¶142-143.
`
`In Alger, remote computer 149 operates as a data source for PDA 120, which
`
`transmits the data to monitor 147 for display. Lippman, ¶144. Thus, PDA 120
`
`operates as a data transmitter, and monitor 147 operates as a data receiver. Id.
`22
