`1 of 40
`
`
`
`SCOPE AND CONTENT OF THE PRIOR ART (CARMEL)
`
`As a factual matter, the scope and content of Carmel concerns:
`
`• The object of performing internet streaming from commonly available
`hardware using widely supported standards.
`
`• Dividing the stream into time-sequenced slices in one or more encodings.
`
`• Transmitting the slices at the selected encoding to the user system, beginning
`with the most recently available slice or an earlier slice as may be selected by
`the user.
`
`• Seeking to sustain the transmission of the successive slices at a rate generally
`equal to the rate at which the slices are being generated, so as not to get
`ahead of or fall behind the program.
`
`• Commonly known as “push”.

`
`
`
`DIFFERENCES BETWEEN CLAIMED SUBJECT MATTER AND THE PRIOR ART
`
`• Claimed Subject Matter:
`
`o Analysis must address each and every limitation, and the claims as a whole.
`
`o It is impossible for an internet streaming mechanism to comply with all of the
`’824 claim limitations unless –
`
`• Content is divided into a plurality of time-sequenced elements.
`
`• The client originates successive requests that identify by serial ID each and
`every element to be sent in response to each successive request.
`
`• Prior Art:
`
`o Carmel discloses only a single request to start a stream from a specified
`starting point.
`
`OBVIOUSNESS ANALYSIS MUST BE CONSISTENT WITH THE ABOVE FINDINGS

`
`
`
`PETITION RELIES ON BOTH FIGS. 6A AND 6B OF CARMEL FOR “INDIVIDUAL
`REQUEST” [MIS]CHARACTERIZATION
`
`• Pet. at 26: “the request for a particular slice of data stream 40 specifies the
`serial indicator (slice index) of the requested slice … Carmel Figure 6A confirms
`this process is repeated for each slice.”
`
`• Pet. at 29: “Carmel teaches that after the client 30 selects a particular slice,
`the client 30 downloads that slice. (Polish, ¶138; Carmel, 8:1-11, 8:32-41; see
`also id., 2:1-21, 3:63-66, 4:7-11, 10:24-54, Figs. 6A and 6B, 13:30-35.)”
`
`• Pet. at 38: “Figures 6A and 6B show that Carmel reflects a classic ‘client-pull’
`streaming system where the data recipient is responsible for selecting the data
`to be transmitted.”
`
`• Pet. at 40: “data slices are sent by the server 36 only in response to requests
`from clients 30 … this confirmed by Figs. 6A and 6B (which show that after
`each slice is selected and downloaded, the process repeats)”.

`
`
`
`GOOGLE’S EXPERT, DR. POLISH, CONFIRMED HIS RELIANCE ON BOTH FIGS. 6A AND 6B OF
`CARMEL AS DISCLOSING SUCCESSIVE INDIVIDUAL SLICE REQUESTS BY SERIAL ID
`
`• Dr. Polish: As in the Petition, Dr. Polish maintained that both Figures 6A and 6B
`represented pulls. EX1002 ¶ 176: “Figs. 6A and 6B … show that after each slice is
`selected and downloaded, the process repeats.”
`
`• EX1002 ¶ 182: Similarly characterizing both Figs. 6A and 6B and showing them in a
`side-by-side illustration to highlight their similarity and argue the point.
`
`• Asked to describe the difference, Dr. Polish stated: “So the difference is 6B has a step
`in there to choose the level and to determine link rate.” EX2006-102:5-17 (question)-
`104:5-18 (answer).
`
`• Note – the Petition and its expert support were presented on the basis that both
`Figs. 6A and 6B were directed to “classic ‘client pull’”. Pet. at 38.

`
`CARMEL DISCLOSES THE SERVER PUSHING SUCCESSIVE ELEMENTS FROM A
`SELECTED STARTING SLICE
`
`• Both Figs. 6A and 6B show only “HTTP FROM SERVER”.
`
`• Nothing anywhere in Carmel addresses any specific HTTP interactions
`between client and server.
`
`• HTTP 1.1, referenced in col. 2 of Carmel, added the ability for the server to
`push successive data elements in response to a single initiating request.

`
`CARMEL DISCLOSURES
`
`• Textual disclosure concerning Fig. 6A is in col. 10: “Responsive to a user input, client 30
`selects an appropriate starting slice and begins to download and decode (decompress)
`files 42, 44, 46, etc.”
`
`• GOOGLE ITSELF (Pet. at 29-30) tells us what “download” means!
`
`• A POSITA would understand that the client “downloading” the specified slice of
`data stream 40 involves “sending, by the server system,” the specified slice of
`data stream 40. (Polish, ¶¶ 139-140.) A POSITA understands that the term
`“downloading” means receiving a file on one machine (such as a remote
`personal computer) that has been sent from another machine (such as a
`server) via a communications means, such as over the Internet. (Id.)
`
`• No inference here whatsoever that “begins to download … files 42, 44, 46, etc.” implies
`that the server can send the files only responsive to successive individual requests for
`“file 42”, “file 44”, “file 46”, etc.

`
`EVERY POINT SUPPORTED BY PO’S EXPERT MR. HOARTY
`
`• Hoarty (EX2002) addresses principles of operation of Carmel at ¶¶ 61-69.
`Quote –
`
`“I disagree with these views of Carmel expressed in the Petition and by
`Dr. Polish. A POSITA would not understand Carmel to disclose an
`individual request (pull) form of streaming. To the contrary, as I have
`explained, a POSITA would understand Carmel as disclosing that the
`server pushes successive stream slices from a designated starting
`slice.” (EX2002 ¶ 62).
`
`• Mr. Hoarty then specifically addresses limitations at issue: 1[b] (p36), 1[f]
`(p37), 1[f][i] (p39), i[f][iii] (p42), and 1[f][iv] (p43).

`
`UNTRUE. Look at the questions that were put:
`
`• The actual questions were limited by their terms to a request for a specific file.
`
`• EX1101:65:16-19: “Q. Okay. So if we -- excluding scripting, okay, so let's take
`a system where we're not gonna be using a script. We are using a request for
`a file of data.”
`
`• EX1101-66:1-18: “Q. So I send a request for File A … Would the server send
`me, based on that scenario, File B?”
`To argue based on this that Mr. Hoarty somehow confirmed or
`“admitted” that ALL HTTP requests MUST BE for INDIVIDUAL
`FILES is FALSE.

`
`Shortcomings: 1[b], 1[e], 1[f][i], 1[f][iii], 1[f][iv]
`▪ 1[b]: “supplying, at the server system, media data elements representing the program, each media data
`element comprising a digitally encoded portion of the program and having a playback rate”. EX1001-
`16:43-46.
`
`▪ 1[e]: “receiving requests at the server system via one or more data connections over the Internet, for
`one or more of the media data elements stored in the data structure, each received request specifying
`one or more serial identifiers of the requested one or more media data elements, each received
`request originating from a requesting user system of the one or more user systems”. EX1001-16:52-58.
`
`▪ 1[f][i]: “the data connection between the server system and each requesting user system has a data
`rate more rapid than the playback rate of the one or more media data elements sent via that
`connection”. EX1001-16:64-67.
`
`▪ 1[f][iii]: “the one or more media data element sent are selected without depending on the server
`system maintaining a record of the last media data element sent to the requesting user systems”.
`EX1001-17:4-7.
`
`▪ 1[f][iv]: “all of the media data elements that are sent by the server system to the one or more user
`systems are sent in response to the requests”. EX1001-17:8-10.

`
`LIM. 1[b] {f/k/a c}: (supplying, at the server system, media data
`elements)
`
`• Google: “supplying at the server system” means “creating, at the server system”
`(Pet. at 16). Cites Dr. Polish, EX1002 ¶ 101.
`
`• Carmel – “creates” the slice on computer 34, not server 36.
`
`• Google attempted to address this, but only by a limiting construction:
`
`o All the Petition said was in ¶ 101 of Dr. Polish’s Decl. (EX1002): “ ‘Creating’
`media data elements is certainly one way to ‘supply’ media data elements.”
`
`o Begs the question of where they are created, and what is creating it.
`
`• This is an issue of Google’s own making, due to its extremely contrived claim
`construction.

`
`• But this new argument on Reply, based on aggregation of
`components, is also contrived.
`• Nothing else in the claim even could relate to anything performed
`by computer 34 in Carmel.
`• There is nothing in the claim to suggest that some kind of server
`“system” extends beyond the server itself.

`
`o “data rate” of what? Limitation says “of the data connection” – Carmel
`fails to disclose this.
`▪ data connection must sustain its capability over the duration of
`playback. Not an instantaneous rate as clearly posited in prior PTAB
`decision. EX2011 at 20 (’141 Patent Remand Decision) (distinguishing
`any “overall rate” for purposes of the ’141 claims there at issue).

`
`o This is slice-wise alternation, sending slices alternately on different links.
`EX1003-2:60-63.
`
`o This concedes that each slice is being sent slower than the playback rate,
`and is not consistent with the ’824/’636 patent disclosures.
`
`o Carmel only says that the aggregate rate is “generally sufficient” (EX1003-
`2:67), which in the case of Carmel’s push would be equal to the playback
`rate.
`
`▪ Carmel never says that the aggregate is faster than the playback rate.
`
`o Carmel repeats seven times (specifically for download process) merely that
`the data rate must be “generally equal to” the playback rate.

`
`o Claimed data rate “of the data connection” not met by a transient

`
`Google’s Reply on Chunked encoding:
`
`• Google, arguing that HTTP must be for files, cites Swaminathan.
`
`• But Polish conceded that Swaminathan was referring to chunking
`within the fragments, not the fragments themselves being chunks.

`
`Reply-18: “Mr. Hoarty agree[s] that when the slices are stored as individual files,
`separate HTTP requests must be sent for each file”
`
`UNFOUNDED.
`
`•
`
`•
`
`•
`
`The actual question was limited by its terms to a request for a specific file.
`
`“Q. Okay. So if we -- excluding scripting, okay, so let's take a system where
`we're not gonna be using a script. We are using a request for a file of data.”
`EX1101:65:16-19.
`
`To argue based on this that Hoarty somehow confirmed that all HTTP
`requests must be for individual files is FALSE.

`
`Google Reply presents a FLIP FLOP on Carmel’s Fig. 6B embodiment
`
`• The Petition argues Figs. 6A and 6B in the same breath, throughout.
`
`• On Reply, Google tries to argue for the first time that Carmel’s Fig. 6A is materially different from
`Fig. 6B.
`
`o Reply at 17-18, arguing original Israeli filing, without multi-level embodiment.
`
`o But - dependent claim structure makes sense only if mechanism consistent with single-level
`claims.
`
`o Carmel’s disclosure of multi-level is introduced as “Alternatively or additionally.” EX1003-7:44-
`49. “Additionally” means simply adding multi-level capability to the base embodiment.
`
`o Dr. Polish conceded the same, as to the difference between 6A and 6B. So the difference is 6B
`has a step in there to choose the level and to determine link rate.” EX2006-102:5-17 (question)-
`104:5-18 (answer).

`
`•
`
`“Mutatis mutandis” – EX1003-13:7-10 and EX1003-13:30-35.
`
`o Raised in the Petition at 32, but simply to seek to apply the timing of delivery in upload process equally to
`download process.
`
`• Google’s citation to EX1003-13:30-35:
`
`o “it will be understood that similar methods are applicable, mutatis mutandis, to the method of downloading
`the files from server 36 to clients 30”.
`
`o Allegedly (according to Google) “confirming techniques used for upload are applicable to download in Fig.
`6A” (Reply at 11).
`
`•
`
`Yet, Google doesn’t dispute that the upload is a push. Isn’t this inconsistent on its face?
`
`o Google’s expedient, in its Reply – on top of transposing Carmel’s 34→36 process onto 36→30, would now
`also interchange client 30 and server 36.
`
`o Magically turns “push” into “pull.”
`
`o There is no other way to read the Reply at 24, than to be proposing such a role reversal.
`
`THIS DOUBLE INTERCHANGE PROPOSED IN THE REPLY IS A RESULT-ORIENTED AFTERTHOUGHT,
`NOT “PRINTED PUBLICATION” DISCLOSURE.

`
`
`
`LIM. 1[f][iv] (f/k/a k): (all elements sent requested by ID)
`
`The ENTIRE ARGUMENT on this is at pages 40-41 of the Petition, and it
`unmistakably argues Carmel only as teaching successive individual slice
`requests by the client, each by serial ID:
`
`“Server 36 cannot send data slices without the client’s input and selection. Not only is this
`confirmed by Figs. 6A and 6B (which show that after each slice is selected and downloaded,
`the process repeats), a POSITA would understand from the overall disclosure in Carmel that
`the clients 30 control which slices are requested from (and therefore sent by) the server
`system.” (Pet. at 40)
`
`“Likewise, for Carmel’s lag recovery … A POSITA would understand that since the client 30 is
`changing the quality level of the slices, that the client 30 is controlling which data slices (and
`at what quality) are being requested and sent by the server. (Polish, ¶176.) Accordingly, all
`data slices that are sent by server 36 “are sent in response to” client requests for such data
`slices. (Id.)” (Pet. at 41)

`
`Only two contentions:
`
`• Ravi, but only as to 1[f][iii] (a/k/a limitation i) – as fast as
`connection allows.
`
`• Narrayan, but only as to preamble.
`
`• Neither matters.
