`Patent No. 7,095,945 B1
`Petitioner’s Reply
`
`In its June 26, 2015 Institution Decision on U.S. Patent No. 7,095,945 (the
`
`“’945 Patent”), the Board correctly found that Petitioner LG Electronics Inc. is
`
`likely to prevail in showing that (a) claim 18 is obvious over U.S. Patent No.
`
`6,397,000 (“Hatanaka”) (Ex. 1006) and (b) claim 18 is obvious over Hatanaka in
`
`view of U.S. Patent 6,591,058 (“O’Connor”) (Ex. 1007). See Decision (“Dec.”),
`
`Paper 20, at 22. Nothing in Patent Owner’s Response should disturb that
`
`conclusion. Patent Owner’s Response is based entirely on a narrow reading of
`
`Hatanaka and an attempted redrafting of claim 18. Thus, for the reasons set forth in
`
`the Petition and further explained below, claim 18 of
`
`the ’945 Patent
`
`is
`
`unpatentable.
`
`I.
`
`CLAIM CONSTRUCTION
`
`A.
`
`“program portion” does not require construction
`
`As explained in the Petition, the terms of the ’945 Patent should be given
`
`their broadest reasonable construction in light of the specification. Petition, at 5-6.
`
`In its preliminary response, Patent Owner argued for a construction of “program
`
`portion” that the Board rejected in its Institution Decision, finding that “Patent
`
`Owner does not specify how much less than all of a program constitutes a portion.”
`
`Dec., at 6-7.
`
`As the Board correctly found in its Institution Decision, the term “program
`
`1
`
`

`
`Case IPR2015-00321
`Patent No. 7,095,945 B1
`Petitioner’s Reply
`
`portion” should be given its plain meaning because it is readily understood by a
`
`person of ordinary skill in the art in view of the ’945 specification and “the
`
`antecedents in claim 18 convey the necessary meaning.” Dec., at 6. Because “claim
`
`18 recites no limits on the first and second portions, other than each being a
`
`portion, i.e., some or all, of the first program” the term “program portion does not
`
`require any construction and should be given its broadest reasonable construction,
`
`plain meaning. Dec., at 7. Patent Owner simply recycles the same arguments with
`
`respect to “program portion” and similarly still fails to specify how much less than
`
`all a program constitutes a portion.
`
`Therefore, Petitioner respectfully requests that the Board again reject Patent
`
`Owner’s proposed construction for “portion” because the term “program portion
`
`does not require any construction and should be given its broadest reasonable
`
`construction, plain meaning.” Dec., at 7.
`
`B.
`
`“selecting a first program from the multiplexed packetized data
`stream”
`
`The phrase “selecting a first program from the multiplexed packetized data
`
`stream” in claim 18 should be given its plain meaning in view of the claim
`
`language and the ’945 specification. While Patent Owner does not expressly
`
`propose a construction for this term, it is clear from its Response that Patent Owner
`
`is attempting to improperly narrow claim 18 to require that the first demultiplexer
`
`2
`
`

`
`Case IPR2015-00321
`Patent No. 7,095,945 B1
`Petitioner’s Reply
`
`perform the selecting step. Response, at 31 (“Hatanaka fails to disclose a first
`
`demultiplexer that receives a multiplexed packetized data stream and selects a first
`
`program from the multiplexed packetized data stream for all three modes of
`
`operation.”); see also id. at 36-38. Contrary to Patent Owner’s interpretation, claim
`
`18 does not recite “selecting a first program from the multiplexed packetized data
`
`stream” at the first demultiplexer. Rather, claim 18 is silent as to what structure is
`
`performing the “selecting.” Furthermore, other than in the claim language, a first
`
`and second demultiplexer are only mentioned in the abstract of the ’945 Patent.
`
`There, the only disclosure is that the first demultiplexer receive the multiplexed
`
`packetized data steam, which is a different limitation of claim 18. Finally, a person
`
`of ordinary skill in the art would not understand claim 18 to require that the first
`
`demultiplexer perform the step of selecting. See Ex. 1012, Schonfeld Supp. Decl.,
`
`at ¶5. Patent Owner’s argument that the first demultiplexer must do the selecting in
`
`this step of claim 18 is simply not supported by the plain language of the claim, or
`
`the ’945 Patent specification and should be rejected. The phrase “selecting a first
`
`program from the multiplexed packetized data stream” in claim 18 should be given
`
`its plain meaning in view of the claim language and ’945 specification.
`
`II.
`
`CLAIM 18 IS OBVIOUS OVER HATANAKA
`
`Patent Owner argues that claim 18 is not obvious in view of Hatanaka based
`
`3
`
`

`
`Case IPR2015-00321
`Patent No. 7,095,945 B1
`Petitioner’s Reply
`
`on an improper
`
`reading of claim 18 and a narrow reading of Hatanaka.
`
`Specifically, Patent Owner challenges Hatanaka based on two primary grounds.
`
`Patent Owner argues that Hatanaka does not disclose the same demultiplexer to
`
`receive a multiplexed packetized data stream and select a first program from the
`
`multiplexed packetized data stream. Response, at 5. Patent Owner also argues that
`
`Hatanaka does not disclose simultaneous recording and playing back different
`
`portions of the same program. Response, at 4. Each of these attacks is unavailing.
`
`As such, and as further set forth in the evidence of record, claim 18 is obvious over
`
`Hatanaka.
`
`A.
`
`Hatanaka Discloses A First Demultiplexer For Receiving The
`Multiplexed Packetized Data Stream As Required By Claim 18
`
`As discussed in the Petition, the first demultiplexer corresponds to the
`
`interface 12 and the second demultiplexer corresponds to demultiplexer 9.
`
`Petition, at 26. Patent Owner argues that Hatanaka does not disclose the same
`
`demultiplexer to receive a multiplexed packetized data stream and select a first
`
`program from the multiplexed packetized data stream. Response, at 5. But claim 18
`
`requires no such thing. Notwithstanding Patent Owner’s argument, demultiplexer
`
`12 corresponds to the first demultiplexer for all three modes of claim 18.
`
`1.
`
`Patent Owner Applies A Narrow Reading of Claim 18
`
`First, as explained above, nothing in claim 18 requires that
`
`the first
`
`4
`

`Patent No. 7,095,945 B1
`Petitioner’s Reply
`
`demultiplexer select a first program from the multiplexed packetized data stream.
`
`All claim 18 requires is that
`
`the first demultiplexer receive the multiplexed
`
`packetized data stream. As can be seen in claim 18 below, each mode only requires
`
`receiving at the first demultiplexer:
`
`18. A method comprising:
`
`determining a mode of operation;
`
`during a first mode of operation:
`
`receiving a multiplexed packetized data stream at a first
`demultiplexer;
`selecting a first program from the multiplexed packetized data
`stream;
`decoding a video portion of the first program for display;
`during a second mode of operation:
`receiving the multiplexed packetized data stream at the first
`demultiplexer;
`selecting the first program from the multiplexed packetized data
`stream;
`storing the first program;
`during a third mode of operation:
`receiving the multiplexed packetized data stream at the first
`demultiplexer;
`selecting the first program from the multiplexed packetized
`data stream;
`
`5
`
`

`
`Case IPR2015-00321
`Patent No. 7,095,945 B1
`Petitioner’s Reply
`
`storing a first program portion of the first program;
`providing the first program portion to a second demultiplexer;
`selecting at the second demultiplexer a video portion of the first
`program portion;
`decoding the video portion of the first program portion for
`display; and
`storing a second program portion of
`simultaneous to the step of decoding.
`
`the first program
`
`Claim 18 does not require that any particular element, such as the first
`
`demultiplexer, perform the selecting step. While mode three specifies selecting at
`
`the second demultiplexer,
`
`there is no requirement
`
`in claim 18 that
`
`the first
`
`demultiplexer do any selecting. Dr. Mangione-Smith agreed this is not a literal
`
`requirement of claim 18. Ex. 1011, Mangione-Smith Tr., at 60:23-61:3; see also
`
`Ex. 1012, Schonfeld Suppl. Decl., at ¶5. Moreover, the fact that Patent Owner
`
`expressly claimed selecting at the second demultiplexer during mode three strongly
`
`suggests that the absence of an express disclosure of an element that does the
`
`selecting in mode one was intended to be claimed broadly.
`
`2.
`
`The ’945 Patent Does Not Narrow The Meaning Of The
`“First Demultiplexer”
`
`Second, the ’945 Patent never defines the first and second demultiplexer.
`
`The only mention of a first and second demultiplexer is in the Abstract of the ’945
`
`6
`
`

`
`Case IPR2015-00321
`Patent No. 7,095,945 B1
`Petitioner’s Reply
`
`specification, which only discloses that
`
`the first demultiplexer
`
`receive a
`
`multiplexed packetized data stream:
`
`stream carrying
`A multiplexed packetized data
`real-time
`multimedia programs is received at a first hardware demultiplexer.
`Based on a user input, a video and timing portion of a program
`associated with the multiplexed packetized data stream can be stored
`for subsequent display. One type of subsequent display is time shifted
`display, where the stored portion of the program is played back while
`new portions of the program are being stored. During time shifted
`play back, a second hardware demultiplexer can be used, so that
`one demultiplexer stores new data and maintains a current clock value
`while the other decodes and displays the stored data.
`Ex. 1001, at Abstract (emphases added). Dr. Mangione-Smith also could not
`
`identify any portion of the ’945 Patent
`
`that discussed the first and second
`
`demultiplexers of claim 18. Ex. 1011, Mangione-Smith Tr., at 64:18-24. He only
`
`assumed it did, but his assumption is not based on any evidence in the intrinsic
`
`record.1
`
`1 He also could not identify any portion of the specification that explains
`
`how a mode of operation is determined in the context of claim 18. Ex. 1011,
`
`Mangione-Smith Tr., at 47:2-13.

`
`Under a Proper Reading of Claim 18, Hatanaka Discloses
`The “First Demultiplexer”
`Hatanaka discloses “receiving a multiplexed packetized data stream at a
`
`first demultiplexer” in all three modes and “selecting a first program from the
`
`multiplexed packetized data stream” also in all three modes. Hatanaka explains
`
`that Figs. 1 and 6 depict receiving a digital broadcasting signal, which is a
`
`multiplexed packetized data stream. Ex. 1006, at 6:18-20. As can be seen in Fig. 6,
`
`that data stream travels through tuner 5, then QPSK Demodulator 6, then FEC 7
`
`and then the same stream is provided to both interface 12 and demultiplexer 9,
`
`through switch 8 set to contact a. Dr. Mangione-Smith agreed that the same stream
`
`is received at both interface 12 and demultiplexer 9. Ex. 1011, Mangione-Smith
`
`Tr., at 96:20-98:11. 2 He also agreed that nothing precludes interface 12 from
`
`receiving the signal during play mode. Id. at 98:20-99:2. This is shown in
`
`annotated Fig. 6 provided below, which shows the path of the multiplexed
`
`2 Dr. Mangione-Smith also agreed that the ’945 Patent discloses what he
`
`identified as a first and second demultiplexer in Fig. 6 of the ’945 Patent as both
`
`receiving the multiplexed data stream. Ex. 1011, Mangione-Smith Tr., at 70:6:-13.
`
`He also agreed that either demultiplexer could select the first program from the
`
`multiplexed packetized data stream. Id. at 71:8-11.

`
`That is, during all three modes, a multiplexed packetized data stream is
`
`received at interface 12, the first demultiplexer. For all three modes, demultiplexer
`
`9 receives the same stream received at interface 12, selects a program, and
`
`separates and outputs the video portion relating to a specified program.
`
`Specifically, the ’945 Patent explains that:
`
`When the broadcasting signal is outputted from the present device, the
`playback changeover switch 8 is set at a contact to input the output
`from the FEC 7 to demultiplexer 9, which determines a type of a
`respective packet, using the PID57, etc., of the header 50, separates
`only packets of a video, audio, etc., relating to a specified program,
`and then outputs these packets to the MPEG decoder 10.
`Ex. 1006, at 3:16-22 (emphases added). Dr. Mangione-Smith admitted that
`
`demultiplexer 9 selects a program from the multiplexed packetized data stream.
`
`Ex. 1011, Mangione-Smith Tr., at 101:3-23. Hatanaka further explains that both
`
`demultiplexer 9 and interface 12 separate packets of video and audio information
`
`and add information relating to the program to be recorded:
`
`is recorded in the recording/playback
`When the received signal
`device 2, the output from the FEC 7 is inputted to the interface 12,
`which separates packets of video and audio information and
`added information relating to a program to be recorded as in the
`demultiplexer 9. When the received signal is recorded and played
`back by the recording/playback device 2, it is required to also record
`
`10
`
`

`
`Case IPR2015-00321
`Patent No. 7,095,945 B1
`Petitioner’s Reply
`
`and play back program information required for automatic selection of
`a broadcasting station. Thus, in addition to the packets selected by
`the demultiplexer 9,
`the interface 12 also selects a packet of
`program information relating to the program to be recorded and
`converts a part of the packet of program information.
`Ex. 1006, at 3:42-54 (emphases added).
`
`the playback
`When a reproduced picture is to be obtained,
`changeover switch 8 is set at
`the contact b to thereby send a
`reproduced
`packet
`to
`the
`demultiplexer 9.
`The
`demultiplexer 9 automatically selects a broadcasting station on
`the basis of the packet of program information which was selected
`and converted by the interface 12 when the data was recorded,
`and outputs only a packet required for the MPEG decoder 10.
`Video/audio signals are obtained in a manner similar to that in which
`an output is obtained from a broadcasting signal
`Id. at 4:27-35 (emphasis added).
`
`Patent Owner and Dr. Mangione-Smith’s interpretation of claim 18 relies
`
`entirely on an improper reading of claim 18—that the first demultiplexer must
`
`perform both the receiving and selecting steps—and therefore,
`
`it should be
`
`rejected. See Ex. 1011, Mangione-Smith Tr., at 74:8-75:12.
`
`Additionally, claim 18 does not require that all operations follow the same
`
`processing path. Dr. Mangione-Smith admitted that claim 18 does not require all
`
`modes to occur in isolation or at the same time. Ex. 1011, Mangione-Smith Tr., at
`
`11
`
`

`
`Case IPR2015-00321
`Patent No. 7,095,945 B1
`Petitioner’s Reply
`
`54:9-19; Ex. 1012, Schonfeld Suppl. Decl., at ¶6. Thus, while the different modes
`
`operate on different paths in Hatanaka, each path of play, record, and playback
`
`meet the requirements of claim 18 because for all three modes, interface 12
`
`receives a multiplexed packetized data stream. Further, performing the playback
`
`mode necessarily meets the first and second modes of play and record because, as
`
`Dr. Mangione-Smith confirmed, playback is playing content that was previously
`
`stored. Ex. 1011, Mangione-Smith Tr., at 56:14-17.
`
`Therefore, Petitioner has shown by a preponderance of the evidence that
`
`Hatanaka discloses the claimed first demultiplexer recited for all three modes of
`
`claim 18.
`
`B.
`
`Hatanaka Discloses Simultaneous Record And Playback
`
`Patent Owner argues that “Hatanaka’s system will not simultaneous record
`
`and playback the same program, as required by claim 18.” Response, at 26.
`
`Petitioner, however, has not argued that Hatanaka expressly discloses simultaneous
`
`storing and decoding. Instead, as argued in the Petition “[s]imultaneous storing and
`
`decoding would have been obvious to a person of ordinary skill in the art in view
`
`of Hatanaka because Hatanaka discloses a system that allows one to
`
`simultaneously record and decode different portions of a program.” Petition, at 26
`
`(citing Ex. 1006, at 3:42-63, 1:21-22; see also Ex. 1004, Schonfeld Decl., at ¶¶188-
`
`12

`

`

`Petitioner’s Reply
`
`91).
`
`As an initial matter, even under Patent Owner’s previously recited
`
`construction of “program portion,” Hatanaka discloses a first and second program
`
`portion as required by claim 18. A person of skill in the art would have understood
`
`that all video programs are made up of portions. Ex. 1012, Schonfeld Suppl. Decl.,
`
`at ¶¶8-10. For example, a video program may have portions A, B, and C.
`
`Id.
`
`Patent Owner has not pointed to anything in the ’945 Patent to preclude this
`
`reading of claim 18. Thus, Hatanaka’s disclosure of a video program necessarily
`
`discloses program portions.
`
`Further, as the Board correctly found, nothing in Hatanaka precludes storing
`
`a second program simultaneous to the step of decoding. See Dec., at 18. Patent
`
`Owner still fails to identify any disclosure in Hatanaka that precludes storing a
`
`second program of the first program simultaneous to the step of decoding. See id.
`
`Instead, Patent Owner applies a narrow reading of Hatanaka in order to argue that
`
`Hatanaka’s system is different.
`
`As explained in the Petition and Dr, Schonfeld’s Declaration, Hatanaka
`
`describes the recording and playback of broadcasts in Hatanaka and indicates that
`
`playback can occur during recording. Dec., at 18; Petition, at 26; Ex. 1004,
`
`Schonfeld Decl., at ¶¶188-191; Ex. 1012, Schonfeld Suppl. Decl., at ¶11 There is
`
`13
`
`

`Petitioner’s Reply
`
`nothing in Hatanaka that excludes this mode of operation or suggests it would not
`
`have been obvious to one of skill in the art. Dec., at 18.
`
`First, Hatanaka discloses that the VCR storage device is one type of storage
`
`device that could be used in the system of Hatanaka. Ex. 1006, at 9:6-8. For
`
`example, multi-head VCRs were available at the time of the ’945 Patent and were
`
`capable of simultaneous storage and playback. Ex. 1012, Schonfeld Suppl. Decl.,
`
`at ¶12. That is, Patent Owner’s recitation of the state of the art of regarding
`
`recording devices is incorrect. Response, at 24-25.
`
`In addition, other storage
`
`devices, like those mentioned in the ’945 Patent and Hatanaka (e.g., magnetic
`
`disks) were also available and capable of simultaneous storage and playback. Ex.
`
`1012, Schonfeld Suppl. Decl., at ¶¶13-15. Dr. Mangione-Smith concedes a system
`
`could use a multi-head VCR at the time of the ’945 Patent and that the ’945 Patent
`
`also discusses multi-disk units. Ex. 1011, Mangione-Smith Tr., at 43:5-22; Ex.
`
`1001, at 4:66. Such multi-head VCRs could simultaneously record and playback
`
`video data. Ex. 1012, Schonfeld Suppl. Decl., at ¶12.
`
`Second, Hatanaka discloses the VCR storage device is only one option and
`
`could be replaced by a magnetic disk, optical disk, or semiconductor memory. Ex.
`
`1006, at 9:6-8; Ex. 1012, Schonfeld Suppl. Decl., at ¶¶15-16. Dr. Mangione-Smith
`
`admitted that Hatanaka discloses these other storage devices. Ex. 1011, Mangione-

`Petitioner’s Reply
`
`Smith Tr., at 44:2-45:13, 90:15-92:10. Further, Dr. Mangione-Smith admitted that
`
`one of ordinary skill in the art would know how to replace the videocassette
`
`recorder in Hatanaka with those other storage devices. Id. at 92:3-10. As explained
`
`by Dr. Schonfeld, one of skill in the art would understand that any of these
`
`recording devices disclosed in Hatanaka would work in the system disclosed by
`
`Hatanaka, and could simultaneously record and playback video data. Ex. 1012,
`
`Schonfeld Suppl. Decl., at ¶¶12-17.
`
`Therefore, Petitioner has shown by a preponderance of the evidence that
`
`simultaneous record and playback of the same program would have been obvious
`
`in view of Hatanaka.
`
`C.
`
`Hatanaka’s System Would Not Require Significant Modifications
`
`Patent Owner argues that Hatanaka would require significant modifications
`
`to meet the challenged limitations of claim 18. Response, at 42. Any modifications,
`
`however, would have been minor and obvious to one of ordinary skill in the art, as
`
`discussed below.
`
`First, Hatanaka would not require an entire change to the data storage
`
`system. Response, at 43. As discussed above, Hatanaka discloses that the VCR is
`
`just one option for the storage device in the system disclosed in Hatanaka. Indeed,
`
`Patent Owner notes that it is only “the main disclosed recording medium” and,
`
`15
`
`

`
`Case IPR2015-00321
`Patent No. 7,095,945 B1
`Petitioner’s Reply
`
`hence, not the only disclosed recording medium. Response, at 25. Magnetic disks,
`
`one of the options disclosed in Hatanaka, are also disclosed in the ’945 Patent. Ex.
`
`1001, at 4:66. One of skill in the art, upon reading Hatanaka, would understand
`
`that it would be a simple substitution of recording devices and no additional
`
`computer or bandwidth would be necessary. Ex. 1012, Schonfeld Suppl. Decl., at
`
`¶17.
`
`Second, Hatanaka would not need to add another packet controller nor
`
`would it require a redesign of the clock recovery system. Response, at 43-44.
`
`Patent Owner argues that “Hatanaka cannot simultaneously record and playback
`
`different portions of the same program, because block changeover switch 25
`
`presents such an operation.” Response, at 27. The switches of Hatanaka, however,
`
`do not preclude simultaneous storing and decoding. One of skill in the art would
`
`have found it obvious to change switch 25 faster, working at double the rate. Ex.
`
`1012, Schonfeld Suppl. Decl., at ¶18.
`
`Additionally, both the data clock 45 and fixed clock 46 could be made
`
`available directly to packet controller 18. Ex. 1012, Schonfeld Suppl. Decl., at
`
`¶18. Neither of these would require significant modifications of Hatanaka. Id.
`
`Accordingly, any modifications to Hatanaka would be minor and obvious to
`
`one of skill in the art. Ex. 1012, Schonfeld Suppl. Decl., at ¶¶16-18.

`
`III. CLAIM 18 IS OBVIOUS OVER HATANAKA IN VIEW OF
`O’CONNOR
`
`Patent Owner contends that Hatanaka in view of O’Connor does not render
`
`obvious claim 18 based on Patent Owner’s alleged deficiencies in Hatanaka.
`
`However, as Patent Owner correctly notes, Petitioner only relies on O’Connor for
`
`the limitation: “storing a second program portion of the first program simultaneous
`
`to the step of decoding.” Response, at 47. And, as the title of O’Connor clearly
`
`states, O’Connor discloses “Time Shifting By Concurrently Recording And
`
`Playing A Data Stream.” Dec., at 19 (citing Ex. 1007, 3:23-28, 33-40, 3:62-4:4);
`
`Pettition, at 7 (citing Ex. 1007, Title). Thus, as with Patent Owner’s arguments in
`
`its Preliminary Response, these same arguments in the Patent Owner Response
`
`must fail.
`
`First, Patent Owner asserts that “O’Connor only discloses the concept of
`
`simultaneously recording and playing back different portions of the same program,
`
`but fails to provide details regarding the hardware that would be needed to
`
`accomplish this.” Response, at 6. Second, Patent Owner asserts that “O’Connor
`
`certainly does not disclose the specific structure recited in claim 18.” Response, at
`
`6. Each of these attacks on the Petition is unavailing.
`
`Notably, Patent Owner has not pointed to anything in claim 18 requiring a
`
`specific hardware or structure. O’Connor discloses the same level of detail as to its
`
`17
`
`

`
`Case IPR2015-00321
`Patent No. 7,095,945 B1
`Petitioner’s Reply
`
`structures as the ’945 Patent discloses. This can be seen in the comparison of Fig. 6
`
`of the ’945 Patent with Fig. 1 of O’Connor provided below.
`
`Incredibly, Dr.
`
`Mangione-Smith described O’Connor Fig. 1 as generic and high-level but refused
`
`to characterize Fig. 6 of the ’945 Patent in the same way. Ex. 1011, Mangione-
`
`Smith Tr., at 108:20-109:19, 110:21-111:7.
`
`Ex. 1001, Fig. 6 compared with Ex. 1007, Fig. 1.
`
`Petitioner also relies on O’Connor solely for the limitation of simultaneous
`
`recording and playback. As the Decision correctly notes, O’Connor discloses this
`
`limitation. Dec., at 19. Dr. Mangione-Smith agreed. Ex. 1011, Mangione-Smith
`
`Tr., at 107:15-20
`
`Therefore, Patent Owner’s arguments fail because Hatanaka in view of
`
`O’Connor renders obvious claim 18 of the ’945 Patent. As such, and as further set
`
`forth in the evidence of record, claim 18 is obvious over Hatanaka in view of
`
`18

`
`O’Connor.
`
`A.
`
`O’Connor Discloses Simultaneous Recording And Playback
`
`As discussed in the Petition and acknowledged by the Board, “O’Connor
`
`discloses a system in which a video stream is recorded simultaneously and
`
`retrieved from the storage unit for immediate playback or delayed playback.” Dec.,
`
`at 19 (citing Ex. 1007, 3:23-28, 33-40, 3:62-4:4). The Board also correctly notes
`
`that O’Connor’s “catch-up” mode “discloses a bypass in which, upon catch up,
`
`recording can be terminated and the incoming video stream can be provided to the
`
`video output directly.” Id. (citing Ex. 1007, at 5:49-67).
`
`The Petition explained that “O’Connor discloses simultaneous recording and
`
`playback of the video stream” and “[p]layback of a video steam includes decoding
`
`the video stream, thus, O’Connor discloses that a data is recorded and decoded at
`
`the same time.” Petition, at 49 (citing Ex. 1007, at 4:9-24, 5:19-33; Schonfeld
`
`Decl., at ¶227,
`
`¶¶245-49). Dr. Mangione-Smith also agreed that O’Connor
`
`discloses simultaneous recording and playback. Ex. 1011, Mangione-Smith Tr., at
`
`107:15-20.
`
`Therefore, Petitioner has shown by a preponderance of the evidence
`
`simultaneously storing and decoding would be obvious over Hatanaka in view of
`
`O’Connor.

`B.
`
`Hatanaka Combined With O’Connor Would Function To
`Perform Claim 18
`
`Patent Owner’s argument that Hatanaka combined with O’Connor would not
`
`function properly is again based on a narrow reading of Hatanaka. Response, at
`
`50. Patent Owner’s argument is based largely on its opinion that Hatanaka only
`
`discloses a digital VCR. Id. at 50-52. However, as explained above in Section
`
`II.B, other types of recording devices, which one of skill
`
`in the art would
`
`understand to be interchangeable with the digital VCR, are disclosed in Hatanaka.
`
`Both experts agree. Dr. Mangione-Smith explained that one of ordinary skill in the
`
`art would know how to replace Hatanaka’s digital VCR with the magnetic disk,
`
`optical disk, or semiconductor devices disclosed in Hatanaka. Ex. 1011, Mangione-
`
`Smith Tr., at 92:3-10. Further, as explained by Dr. Schonfeld, one of skill in the art
`
`would understand that any of these recording devices disclosed in Hatanaka would
`
`work in the system disclosed by Hatanaka and could simultaneously record and
`
`playback video data in view of the express disclosure in O’Connor. Ex. 1012,
`
`Schonfeld Suppl. Decl., at ¶20; see also Petition, at 49-50; Ex. 1004, Schonfeld
`
`Decl., at ¶250.
`
`Therefore, Petitioner has shown by a preponderance of the evidence that one
`
`of skill in the art would be motivated to combine O’Connor with Hatanaka to meet
`
`the limitation of claim 18 of simultaneously storing and decoding video data.

`IV. DR. SCHONFELD’S DECLARATION SHOULD BE AFFORDED
`FULL WEIGHT
`
`Patent Owner disingenuously argues that Dr. Schonfeld’s declaration should
`
`be given no weight because it mirrors the Petition. To the contrary, Dr. Schonfeld
`
`provides expert opinions supported by technical analysis and factual support that
`
`further bolster the arguments made in the Petition.
`
`First, Petitioner incorrectly argues that Dr. Schonfeld’s declaration repeats
`
