`
`
`INTRODUCTORY COMMENTS
`
`DISH Network Corporation (“the Requester") requests reexamination of U.S. Patent No.
`
`6,233,389 B1 (“the '389 patent") under 35 U.S.C. §§ 302-307 and 37 CPR. § 1.510. The '389
`
`patent issued on May 15, 2001 and is currently assigned to TiVo, Inc.
`
`The '339 patent is directed to a system for simultaneously storing and playing back
`
`multimedia data, such as a television broadcast program. The system allows a user to rewind or
`
`fast forward through the program while viewing it. The '3 89 patent issued with four independent
`
`claims. Independent claims 1 and 32 are “hardware.claims" directed to the hardware elements
`
`for effecting simultaneous storage and play back. Independent claims 31 and 61 are “software
`
`claims” directed to the corresponding software elements. This request for reexamination is
`
`directed solely to the two independent software claims.
`
`Claims 31 and 61 each recite a physical data source that “parses" video and audio data
`
`from broadcast data and three software “objects" that form a software pipeline through which the
`
`video and audio data is moved. A “source” object extracts the video and audio data from the
`
`data source and fills empty buffers obtained from a “transform” object. The transform object
`
`stores the full buffers of data to a storage device and then retrieves them for transfer to a ‘‘sink’‘
`
`object. The sink object sends the data to a decoder for output to a display.
`
`During a co-pending litigation discussed infra, claims 31 and 61 were broadly construed.
`
`For example, the District Court construed the term “object" as “a collection of data and
`
`operations” based on TiVo’s urging. Furthermore, TiVo asserted that “parsing” video and audio
`
`data was satisfied by detecting video frames in a data stream and generating an index or table of
`
`the start of the detected video frames and their storage location on a hard drive.
`
`The Requester is aware of two references that, in combination, raise a substantial new
`
`question of patentability in view of TiVo’s construction. The first reference — U.S. Patent No.
`
`Ia-992 863
`
`l
`
`7
`
`
`
`6,018,612 to Thomason et al. (“Thomason”) — discloses a system for simultaneous storage and
`
`play back of a television broadcast program.
`
`It allows a user to rewind or fast forward through
`
`the program while viewing it. The system employs three buffers controlled by three direct
`
`memory access controllers that move the data through the system. The DMA controllers are, in
`
`turn, supervised by a microprocessor that runs sofiware. Thomason thus expressly discloses
`
`each ofthe three recited objects when broadly constmed as a collection of data and operations.
`
`The second reference — US. Patent No. 5,949,948 to Krause et al. — discloses a
`
`compressed video data retrieval system for supporting rnulti-speed modes such as reverse and
`
`"fast forward. The system employs an I-frame detector for analyzing incoming MPEG-formatted
`
`data to detect I-frames, and the system then generates a table or index of the storage locations of
`
`the detected I-frames.
`I—frames are complete in that they are not dependent on any other frames
`to complete a picture, so the system can retrieve data’more efficiently by detecting and
`
`reproducing the appropriate I-frame for the selected speed of reverse or fast forward. It is
`
`submitted that it would have been obvious to one of ordinary skill in the art to employ the
`
`indexing of detected I-frames in the system of Thornason when Thomason receives MPEG-
`
`forrnatted data or encodes received data into an MPEG forrnat. Indexing the detected I-frames,
`
`r‘.e., “parsing,” would allow the system of Thomason to more efficiently perform operations such
`
`as reverse or fast forward.
`
`The combination of Thomason and Krause was never considered in the original
`
`examination or in any co-pending proceeding with respect ‘to claims 31 and 61. Thus, the
`
`Requester respectfully requests that an order for reexamination be issued.
`
`la-992863

`
`
`
`II.
`
`CLAIMS FOR WHICH REEXAMINATION IS REQUESTED
`
`This request for reexamination raises the following substantial new question of
`
`patentability with respect to claims 31 and 61 of the '3 89 patent, submitted herewith in the
`
`accompanying Exhibits as Exhibit 1.
`
`Claims 31 and 61 are obvious under § 103(3) in View of Thomason et al. (U.S. Pa1entNo.
`
`6,0!8,612 and submitted herewith as Exhibit 2) and Krause et al. (US. Patent No. 3,949,948 and
`
`submitted herewith as Exhibit 3);
`
`9
`
`
`
`III.
`
`C0-PENDING PROCEEDINGS
`
`The '389 patent is the subject of two co-pending litigations and one co-pending
`
`reexamination. The combination of Thomason and Krause with respect to claims 3] and 61 has
`
`not been considered in any of these co-pending proceedings.
`
`The first co—pendin g litigation is an action styled Ti Vo, Inc. v. Er:hoStar Commuriications
`
`Corp, er al., Case No. 2-O4CV-01 DF, in the United States District Court for the Eastern District
`
`of Texas. TiVo initiated this action against the Requester (then known as EchoStar
`
`Communications Corporation) in 2004.
`
`It asserted that certain digital video recorders of the
`
`Requester infringed the hardware and software claims of the '389 patent.
`
`In 2006, the District
`
`Court entered judgment for TiVo after a jury found that certain hardware and software claims
`
`were infringed.
`
`The Federal Circuit affirmed in part and reversed in part the District Court's judgment.
`
`See Tt'Vo, Inc. v. Echostar Communications Corp, 516 F.3d 1290 (Fed. Cir. 2008). The Court
`
`affirmed the judgment of infringement with respect to the software claims, but reversed the
`
`judgment of infringement with respect to the hardware claims. That is, the Court found only
`
`claims 31 and 61 of the '339 patent to be infringed. The combination of Thornason and Krause
`
`with respect to claims 3] and 61 was not raised at trial nor considered on appeal.
`
`The second co-pending litigation is an action styled DISH Network Corporation er al. v.
`
`TiVo, Inc, Case No. 1:08-CV-00327-JJF, in the United States District Court for the District of
`
`Delaware. This action was initiated by the Requester in May 2008 against TiVo after TiVo
`
`publicly stated that the Requester-’s new digital video recorder infringes the '3 39 patent. The
`
`Requester is seeking declaratory relief that it does not infringe any claims of the '3 39 patent,
`
`including software claims 31 and 6]. This co-pending litigation has just commenced, and the
`
`combination of Thomason and Krause with respect to claims 31 and 6] has not been considered.
`
`la-992863
`
`4
`
`10
`
`
`
`The co-pending reexamination of the '3 89 patent bears serial no. 90/007,750. In October
`
`2005, the Requester (then known as EchoStar Communications Corporation) requested
`
`reexamination ofcertain hardware claims - t'.e.. claims I, 6, 20, 21, 23, 32, 37, SI and 52 — ofthe
`
`‘389 patent. The request raised substantial new questions of patentability based on 1.1.8. Patent
`
`No. 5,614,940 to Cobbley et al. alone, as well as Krause in combination with another Krause
`
`patent (U .S. Patent No. 6,304,714). The request did not seek reexamination of software claims
`
`31 and 61, nor did it raise any question of patentability based on Thomason alone or Thomason
`
`with Krause as to any claims. In fact, at that time, Thomason was not known to counsel who
`
`prepared the reexamination request.
`
`The reexamination request was granted in December 2005. In the order granting
`
`reexamination, the Examiner indicated that he would reexamine all the claims of the '3 89 patent.
`
`The Examiner subsequently rejected only certain hardware claims based on Gear at al. (U.S.
`
`Patent No. 6,783,882) and Cobbley. The Examiner did not reject the hardware claims based on
`
`Krause and Krause "714 raised in the reexamination request. He found that Krause and Krause
`
`'7l4 did not disclose “parsing" and “separating" the video and audio data as recited in the
`
`hardware claims} In any event, TiVo overcame the rejection of the hardware claims in
`
`November 2007 when the Examiner issued a Notice of Intent to Issue an Ex Pane
`
`Reexamination Certificate confirming the patentability of all the claims, including claims 31 and
`
`61, and it appears that the reexamination certificate will issue shortly. Thus, in the co-pending
`
`reexamination, Thomason (or its combination with Krause) was not used to reject any claims or
`
`even discussed on the record.
`
`Software claims 31 and 61 do not recite ‘‘separating’‘ the video and audio data in addition to
`'
`“parsing" like the hardware claims. Claims 3] and 6] are accordingly broader in this aspect.
`
`Ia-992 863
`
`11
`
`
`
`The only mention of Thomason in the co-pending reexamination was in an lnforrnation
`
`Disclosure Statement filed in March 2006 by TiVo. The statement listed Thomason with 232
`
`other references. The statement did not explain the content or relevance of any of the listed
`
`references, including Thomason. MPEP 2256 explains that the Examiner's consideration of a
`
`reference listed in an information disclosure statement is limited to what is provided by the party
`
`submitting the statement:
`
`When patents, publications, and other such items of information are submitted by
`a party (patent owner or requester) in compliance with the requirements of the
`rules, the requisite degree of consideration to be given to such information will be
`nomtally limited by the degree to which the party filing the information citation
`has explained the content and relevance of the information. The initials of the
`examiner placed adjacent to the citations on the form PTOISB/08A and 08B or its
`equivalent, without an indication to the contrary in the record, do not signify that
`the information has been considered by the Examiner any further than to the
`extent noted above.
`
`TiVo’s statement did not provide any discussion of Thomason’s content or relevance, so the '
`
`consideration of Thomason was accordingly limited. This conclusion is underscored by the
`
`remainder of the reexamination record as there is no discussion of Thomason at all. Thus, die
`
`question of patentability raised in this Request is new to any question of patentability addressed
`
`in the co-pending reexamination.

`
`SUMMARY OF THE '389 PATENT
`
`A.
`
`Brief Overview
`
`The ‘389 patent (submitted herewith as Exhibit 1) is directed to a system for
`
`simultaneously storing and playing back multimedia data, such as a television broadcast
`
`program. The ability to simultaneously store and play back the program allows the user to
`
`rewind-or fast forward through the program while viewing it. Fig. 1 (reproduced below)
`
`illustrates the system.
`
`FIG. 1
`
`Input Module 101 receives a television input stream and outputs an MPEG formatted
`
`stream. For example, if the television input stream is an analog signal, Input Module 101
`
`converts the signal into an MPEG format through the use of video and audio encoders.
`
`(Col. 2,
`
`lines 10-14 and Col. 3, lines 49-52.) The MPEG formatted stream is then sent to Media Switch
`
`102.
`
`Media Switch 102 includes a “parser.” The parser “parses the stream looking for MPEG
`
`distinguished events including the start of video, audio or private data segments.” (Col. 5, lines
`
`3-6.) When a video or audio segment is distinguished, the parser indexes the segment in an
`
`Ia-992863
`
`13
`
`
`
`appropriate video or audio circular buffer represented by memory 104. (See also Fig. 4 at video
`
`buffer 410 and audio buffer 411.)
`
`At the same time, the parser places events corresponding to the parsed video and audio
`
`segments in an event buffer or memory I04. (Col. 5, lines 6-19.) From the events in the event
`
`buffer, the system generates a sequence of logical segments that correspond to the parsed MPEG
`
`segments in the audio and video buffers. (Col. 5, lines 36-38.) The logical segments are then
`
`gathered together in a PBS buffer and stored in hard disk or storage device 105:
`
`When a PES buffer is written to storage, these logical segments are written to the
`storage medium in the logical order in which they appear. This has the effect of
`gathering components of the stream, whether they be in the video, audio or
`private data circular buffers,
`into a single linear buffer of stream data on the
`storage medium. (Col. 6, lines 2-7.)
`
`The stored data is thereafter read from the storage device and decoded into an analog signal by
`
`Output Module 103 which includes an MPEG video decoder. (Col. 4, lines 5-9.)
`
`Claims 31 and 61 are directed to the program logic within CPU 106 that controls the
`
`movement of data through the system. The program logic has three conceptual components as
`
`illustrated in Fig. 8 below.

`80)‘
`
`buffers
`of data
`
`decoder
`
`la-992 863
`
`14
`
`
`
`The first component is sources 301. Sources 801 accept data from an encoder and
`
`package the data in buffers acquired from trans forms 802. Sources 801 then push the buffers
`
`down the pipeline as shown in Fig. 8 above. (Col. 7, lines 58-61.) Transforms 302 write the
`
`buffers to a file on the storage medium or hard disk 804. The buffers are pulled out a later time -
`
`.".e., a temporal transform — and then sent down the pipeline to be sequenced with the stream.
`
`(Col. 8, lines 3-8.) Sinks 803 take the buffer from transforms 802 and send the data to a decoder.
`
`The '3 89 patent describes the use of object-oriented programming language, e.g., the CH
`
`programming language, to implement the program logic illustrated conceptually in Fig. 8 above.
`
`Specifically, the '3 S9 patent describes the use of a “source object" 901, a “transform object” 902
`
`and a “sink object“ 903 corresponding to sources 801, transforms 802 and sinks 803. (Col. 8,
`
`lines 9-18; Fig. 9.) A “control object" 917 is also employed to accept commands from the user.
`
`(Col. 9, lines 25-32.)
`
`The source, transform and sink objects operate in conjunction with the hardware elements
`
`described above in Fig. 1. The source object “takes data out of a physical data source, such as
`
`the Media Switch [102 ofFig. 1], and places it into a PES buffer." (Col. 8, lines 43-45.) The
`
`'389 patent describes that the source object calls the transform object for a buffer to fill. (Col. 8,
`
`lines 45-48.) The transform object provides the empty buffer to the source object and then takes
`
`the full buffer from the source object and stores it on hard disk or storage device [05 in Fig. 1..
`
`(Col. 9, lines 2-9.) The sink object calls the transform object for a firll buffer and then sends the
`
`data to a decoder in Output Module 103 of Fig. 1. (Col. 9, lines 10-16.) It then releases the
`
`empty buffer to the transform object for use again by the source object. (Col. 8, lines 55-59.)
`
`Under this system, the source object must wait for the transform object to provide an
`
`empty buffer. Similarly, the sink object must wait for the transform object to provide a full
`
`la-992 863
`
`15
`
`
`
`buffer. According to the '3 89 patent, “[t]his means that the pipeline is self-regulating; it has
`
`automatic flow control.” (Col. 8, lines 48-49.)
`
`B.
`
`The Prosecution History Of The ‘I539 Patent
`
`The application that matured into the '3 89 patent was filed on July 30, 1998 with 61
`
`claims, including claims 31 and 61. In a first Office Action dated November 22, 2000, the
`
`Examiner allowed claims 31 and 61 , but rejected the remaining claims under § 112, second
`
`paragraph. TiVo responded to the Office Action by amending the rejected claims in an
`
`Amendment dated December 13, 2000. The Examiner thereafter allowed all the claims and
`
`passed the application to issuance. Neither Thornason nor Krause was considered by the
`
`Examiner in allowing the claims.

`
`
`
`DETAILED EXPLANATION OF PERTINEN CY OF PRIOR ART TO THE
`CLAIMS
`
`A.
`
`Claims Must Be Given Their “Broadcst Reasonable Construction”
`
`The standard for reexamination is well established: claims must be given their broadest
`
`reasonable construction consistent with the specification. See MPEP § 2258 K0). The
`
`requirement that claims be given their broadest reasonable construction was detailed in In Re
`
`American Academy ofScience Tech Center, 36'? F.3d 1359 (Fed. Cir. 2004). As explained by
`
`the Federal Circuit in that case, “[g]iving claims their broadest reasonable construction ‘serves
`
`the public interest by reducing the possibility that claims, finally allowed, will be given broader
`
`scope than isjustified.” Id. at 1364 (quoting in Re Ynmomoto. 740 F. 2d 1569, 1571 (Fed. Cir.
`1984)). The Court further stated that “[c]onstruing claims broadly during prosecution is not
`
`unfair to the applicant (or in this case, the patentee), because the applicant has the opportunity to
`
`amend the claims to obtain more precise claim coverage." Id. (citing Famamoro, 740 F.2d at
`
`1571).
`
`As discussed in the Introduction, claims 31 and 61 were broadly construed in the co-
`
`pending T:'Vo litigation. For example, the District Court construed the term “object" — based on
`
`'I‘iVo’s proposed claim construction — as not being limited to an object—oriented computer
`
`programming language, but rather “a collection of data and operations.” Claim Construction
`
`Order, at 26 (hereinafter “Order" and submitted herewith at Exhibit 8); T1‘ Va Inc. ’.'.-' Opposition
`
`Brief On Claim Construction, at 13 and 2] (submitted herewith as Exhibit 7). For its part, the
`
`Federal Ci reuit adopted the District Court‘s construction of “object.” TWO, at 516 F.3d at 1306-
`
`7 (submitted herewith as Exhibit 9).
`
`The Requester disagrees with TiVo’s asserted constructions of claims 31 and 61 in the
`
`co-pending litigation, and the PTO is, of course, not bound by a patent owner’s construction or
`
`la-992863
`
`I l
`
`17
`
`
`
`even a Court’s construction when giving claims their broadest reasonable interpretation during a
`
`reexamination. Nevertheless, TiVo‘s and the Court’s constructions are important to the present
`
`request for reexamination, because it establishes a “baseline” interpretation of claims 31 and 61.
`
`If the claims 31 and 61 are obvious in view of Thomason and Krause based on this “baseline”
`
`interpretation, the claims will necessarily be obvious based on any broader interpretation given
`
`by the PTO.
`
`B.
`
`Claim 31 Is Obvious In View Of Thomason And Krause
`
`A concise explanation of Thomason and Krause is provided below and then followed by
`
`their application to claim 31. A corresponding claim chart is submitted herewith as Exhibit 4.
`
`I.
`
`Thomason
`
`The earliest effective filing date ofThomasor1 (submitted herewith as Exhibit 2) is
`
`October 4, 1993. It thus qualifies as prior art under § l02(e) based upon the filing date of the
`
`339 patent, 5.3., July 30, 1993.’
`
`Thomason is directed to a system that simultaneously stores and plays back a television
`
`program.
`
`it explains that the system allows for functions such as reverse and fast forward and
`
`conventionally employs a main memory, an input buffer memory and an output buffer memory.
`
`In order to enable an uninterrupted storage of a live television program in the
`main memory, and enable uninterrupted and simultaneous retrieval of the
`historical program from the main memory, an input buffer memory and an output
`buffer memory are present. Data arriving for storage in the main memory, while
`the main memory is temporarily busy for another operation, will be stored in the
`input buffer memory, and will be stored at a later moment in the main memory by
`retrieving the data from the input buffer memory. Data will also be requested
`regularly from the main memory to be displayed on a TV screen as a historical
`program. Again,
`the main memory may be temporarily busy for another
`operation, so data must be readily available in the output buffer memory, so as to
`provide continuity of viewing from the user. (Col. 2, lines 36-51.)
`

`
`The corresponding European patent to Thomason — EP 059424! Bl — was first published on
`April 27, 1994 as EP 0594241 Al. The publication qualifies as prior art under § 102(b).

`
`
`
`Thomason discloses an improvement to the conventional system by combining the input
`
`buffer memory and the output buffer memory into a single buffer memory. (Col. 2, lines 54-58.)
`
`This is achieved by recognizing that the input buffer memory should be empty to receive data
`
`and the output buffer memory should be fiill to output data, thereby allowing the same buffer to
`
`be used for input and output. (Col. 2, line 59 to (301.3, line 7.) Fig. 1 (reproduced below)
`
`illustrates one embodiment.
`
`One or more television signals pass through channel selector 1 . Channel selector 1
`
`selects which channels to be stored and which channels to be displayed live.
`
`(Col. 3, lines 39-
`
`43.) The channels selected for storage are digitized by afd converter 2 and then compressed in
`
`real time by data compressor 3. (Col. 3, lines 43-46.) The output is placed in one or more
`
`buffers 4, with one buffer per selected channel. Thornaso
