`
`INTRODUCTION
`
`Petitioner NetNut Ltd. (“Petitioner” or “NetNut”) seeks inter partes review
`and cancellation of claims 1-2, 12, 14-15, 17-19, and 21-29 (“Challenged
`Claims”) of U.S. Patent No. 10,257,319, Ex. 1001 (the “’319 patent” or the
`“Patent”). The Petition is supported by the Exhibits listed above, including the
`Expert Declaration of Keith J. Teruya (Ex. 1005).
`The Patent Owner is Bright Data Ltd. (formerly known as Luminati Net-
`works Ltd.). Since 2018, Patent Owner has been suing its competitors in this
`field (including Petitioner) on numerous patents stemming from two provi-
`sional applications filed respectively in 2009 (relevant to this case) and 2013.
`Despite pursuing ten district court cases, Patent Owner has avoided most efforts
`to obtain PTAB review.1
`The sum and substance of claim 1 of the ’319 patent is simply the ordinary
`process of retrieving content from a web server through a proxy:
`
`second server <—> client (proxy) device <—> web server
`
`Patent Owner has asserted that the manner in which the claim language
`labels the device in the middle (above), as a “client” (rather than a “server”)
`defines a patentably unique “architecture.” However, court constructions have
`rejected the narrow construction of “client” and “server” on which Patent
`Owner would rely to support that argument. Even if one were to accept Patent
`
`1 There were two recent exceptions in IPRs, also brought by Petitioner,
`which were instituted on August 12, 2021. See IPR2021-00458, Paper 11;
`IPR2021-00465, Paper 11.

`
`Petition for Inter Partes Review
`
`Owner’s unreasonably narrow constructions, there are numerous examples of
`proxy retrieval scenarios in the prior art that easily meet the claim requirements.
`The ’319 patent was previously challenged, on the same art presented
`herein, in a petition (by another competitor) whose institution was denied, but
`on discretionary grounds. See Code200, UAB et al. v. Luminati Networks
`Ltd., IPR2020-01266, Paper 18 at 2 (generally, the “’1266 IPR”). The present
`Petition arises in a different posture, being filed very early in relation to the
`lawsuit against Petitioner, such that this case is likely to result in a final written
`decision before the trial in the district court case. That timing, plus the plain
`deficiencies of the ’319 patent, strongly favor PTAB review.

`3. DISCRETIONARY CONSIDERATIONS
`
`Patent Owner sued Petitioner on June 18, 2021 in the Eastern District of
`Texas (“EDTX”), No. 2:2-cv-00225 (the “Related Litigation”) asserting the
`Patent against Petitioner. The Patent was also the subject of a prior IPR by
`another party (IPR2021-01266), in which institution was denied. (There are
`also parallel cases asserting the Patent against other parties.)
`
`Page 10 of 76
`
`
`
`2042-04-319-IPR (US 10,257,319)
`
`Petition for Inter Partes Review
`
`This Petition is being filed very early in the Related Litigation, before even
`the time for Petitioner to answer the complaint.
`3.1. Fintiv Factors
`
`3.1.1. Factor 1—Existence or likelihood of a stay
`
`This IPR is being filed early in the Related Litigation. Whether the court
`will grant a stay is not known, and so this factor should be considered neutral.
`
`3.1.2. Factor 2—Proximity of trial date to final written decision
`
`Because of the early filing of this Petition, a final written decision is likely
`before the EDTX case goes to trial. No trial date has been set. This factor
`strongly favors institution.
`
`3.1.3. Factor 3—Investment in parallel proceedings
`
`There have been no substantive proceedings in the Related Litigation,
`which favors institution.
`
`3.1.4. Factor 4—Overlap in issues raised
`
`There have been no invalidity contentions in the Related Litigation and thus
`there is currently no overlap between this IPR and the Related Litigation. Even
`if there is some possibility of overlap, Petitioner submits this sole consideration
`does not warrant non-institution. If the Related Litigation reaches the invalidity
`contentions phase, Petitioner reserves the right include a stipulation in those
`contentions to mitigate any overlap concerns.
`
`Page 11 of 76
`
`
`
`2042-04-319-IPR (US 10,257,319)
`
`Petition for Inter Partes Review
`
`3.1.5. Factor 5—Whether the parties are the same
`
`The parties in the Related Litigation are the same. However, this proceed-
`ing will likely address the challenged patent before any ruling on the merits in
`the Related Litigation, favoring institution. See Apple Inc. v. Parus Holding,
`Inc., IPR2020-00687, Paper 9 at 21 (this factor can “weigh either in favor of, or
`against, exercising discretion to deny institution, depending on which tribunal
`was likely to address the challenged patent first.”).
`
`3.1.6. Factor 6—Other circumstances including the merits
`
`The broad court construction of “client device” (and its likewise ruling out
`any argument that a client device is specifically not a server) makes it highly
`unlikely that Patent Owner can avoid the art asserted in this Petition, favoring
`institution.
`
`3.2. General Plastic Factors
`
`The Board has recently ruled on General Plastic issues in IPRs 2021-00458
`and -465, involving the same parties, and those decisions provide considerable
`guidance.
`
`3.2.1. Factor 1—Prior petition by same petitioner
`
`Petitioner differs from the prior petitioners in IPR2021-01266, and there
`is no relationship, much less a significant relationship, with them. Since
`Petitioner was not involved with the prior IPR challenging the Patent, this
`
`Page 12 of 76
`
`
`
`2042-04-319-IPR (US 10,257,319)
`
`Petition for Inter Partes Review
`
`factor strongly favors institution. See Valve Corp. v. Elec. Scripting Prods.,
`IPR2019-00062, Paper 11 at 10 (PTAB Apr. 2, 2019) (designated precedential
`May 7, 2019) (“Valve”).
`
`3.2.2. Factor 2—Petitioner’s prior knowledge of asserted art
`
`Petitioner was not even sued on the Patent until a year after IPR2021-01266.
`IPR2021-01266 was filed on July 14, 2020, only shortly after the time
`Petitioner was being sued in an earlier filed EDTX action (No. 2:20-cv-00188),
`on different patents. Petitioner was not sued on the Patent until nearly a year
`later (June 11, 2021). There is no reason Petitioner should have investigated
`prior art relative to the Patent prior to Related Litigation.
`This factor therefore has little applicability and thus favors institution.
`
`3.2.3. Factor 3—Petitioner’s prior receipt of preliminary response or
`institution decision
`
`Both the Patent Owner Preliminary Response (“POPR”) and the Board’s
`Order denying institution in IPR2021-01266 were available to Petitioner prior
`to this Petition. However, since neither provided a substantial roadmap as any
`response to the prior art, this factor is at least neutral.
`Patent Owner’s primary assertions in the POPR consisted of Fintiv ar-
`guments and a narrow construction that would limit the term “client device”
`to consumer devices. See IPR2021-01266, Paper 16 at 4-14, 19-25, 40, 43.
`The arguments on the Fintiv factors provide no guidance as to the prior art,
`while the claim construction defense was mooted by the Markman order in
`
`Page 13 of 76
`
`
`
`2042-04-319-IPR (US 10,257,319)
`
`Petition for Inter Partes Review
`
`another lawsuit on the Patent. See Ex. 1017 at 12 (interpreting “client device”
`broadly to mean a “communication device that is operating in the role of a
`client.”) Hence, the POPR in IPR2021-01266 provides little guidance as to
`technical deficiencies in the Petition beyond those hinging on now-mooted
`claim construction arguments.
`More significantly, the Board’s basis for denying institution of IPR2021-
`01266 was premised on discretionary factors. See IPR2021-01266, Paper 18
`at 2, 6-11. The decision denying institution thus provides no roadmap for
`adapting any challenges based on prior art, and the grounds asserted in this
`Petition remain substantially the same as in the prior petition. This factor thus
`favors institution, or is at least neutral.
`3.2.4. Factor 4—Elapsed time since the petitioner learned of the asserted
`art
`
`This factor, and factor 5 below, concern the situation where the second
`petition is filed by a party using prior art allegedly newly discovered after
`receiving the Board’s unfavorable decision in the first petition. See General
`Plastic at 10.
`In contrast to General Plastic, however, this petition relies upon the same
`art as the Prior petition, favoring institution.
`3.2.5. Factor 5—Explanation of time elapsed since prior petition
`
`Petitioner has proceeded with its own Petition because, since the Prior
`Petition filed by unrelated parties, Petitioner has been separately sued on the
`challenged patent.
`In response to such suit, Petitioner has acted quickly,
`
`Page 14 of 76
`
`
`
`2042-04-319-IPR (US 10,257,319)
`
`Petition for Inter Partes Review
`
`bringing this IPR within about two months of being sued on the Patent. This
`factor thus favors institution.
`3.2.6. Factor 6—The finite resources of the Board
`
`Since there are no other cases before the Board challenging the Patent, this
`factor favors institution. See Valve at 15.
`
`3.2.7. Factor 7—The requirement for a final written decision within a
`year
`
`There is nothing about this case that should impede the Board in rendering
`a decision within a year after institution, favoring institution.
`
`4. OVERVIEW OF THE ’319 PATENT
`
`The ’319 patent resulted from a Track One procedure. Ex. 1002 at
`358. The only art-based rejection was under § 103, based on Fang et al.,
`US2006/0212542, in view of Zaid et al., US2011/0035503. Id. at 302. The
`applicant traversed by arguing that Fang et al. disclosed fetching content from
`the wrong server (id. at 287-88). The subsequent action was an allowance. Id.
`at 46.
`
`4.1. Claims
`
`The Challenged Claims are listed in Ex. 1003.
`The following figure schematically represents the data flow corresponding
`to claim 1, and the steps performed by the intermediate device (in the middle
`of the figure):
`
`Page 15 of 76
`
`
`
`2042-04-319-IPR (US 10,257,319)
`
`Petition for Inter Partes Review
`
`’319 Patent Claim 1 Data Flow
`
`This is the data flow of a conventional “proxy server”—a device that
`stands in the middle to relay requests and responses to and from an ordinary
`web server.
`The only other aspect of claim 1 is that it refers to the device in the middle
`of this diagram, performing the role of a proxy for purposes of the claim, as
`a “client device,” and to the device (on the left), requesting content through
`the middle device, as a “server.” However, the “client” labelling of the middle
`device follows from the fact that it operates in the role of a client relative
`to the web server (on its right). Likewise, the device on the left can be a
`“server” where it otherwise also has a role as a server. Thus, the claim’s mere
`labelling of devices implies very little. There are no structural or procedural
`claim limitations that require either the left-hand or middle devices to have any
`special features or capabilities, other than the ability of the left-hand device to
`act in the role of a server, and the ability of the middle device to act in the role
`of a client. Prior art exists that provides proxy functionality and satisfies these
`minimal additional role requirements.
`
`Page 16 of 76
`
`
`
`2042-04-319-IPR (US 10,257,319)
`
`Petition for Inter Partes Review
`
`As will be individually addressed, the dependent Challenged Claims merely
`recite additional common steps, for example such as that “TCP/IP” is used, or
`that an HTTP header used in the prior art RFC 2616 standard is used, additional
`features commonly found in proxy devices well known in the art.
`
`4.2. Specification
`
`The ’319 patent uses as an example a peer-to-peer swarm of devices,
`provisioned so they can variously act as either “clients” or “servers” (and
`sometimes as both), at various times and under various circumstances.
`In the disclosure, any of a plurality of “communication devices,” running
`a common “acceleration application” 220, can function in different roles,
`including as a “client” (device that requests content, for example for the client’s
`web browser) “agent” (device that obtains content an origin web server and/or
`manages its retrieval from peers), or “peer” (device that continues to cache
`content received while the peer acted as a client or agent):

`
`Network 100 shown in Fig. 3 “contains multiple communication devices,”
`and “each communication device may serve as a client, peer, or agent. . . .”
`Ex. 1001, 4:44-53. The figure shows “peer[s],” a “client,” and an “agent”
`communicating, with the “agent” forming a connection to a server.
`Communication requests generated by applications (e.g., a web browser)
`are intercepted by software running on the same machine. Id. The IP address of
`the content server for the communication request (origin server) is transmitted

`
`to the acceleration server, which provides to the content requester a list of
`agents to use for retrieving content from the IP address of the origin server.
`Id., 13:4-15.
`The requesting device then sends a copy of the communication request
`itself (URL) to each of the specified agents. One or more agents respond with
`a list of peers that have previously seen some or all of the content responsive
`to this request (after checking whether this data is still valid). Id., 13:31-36,
`13:50-61. The client then downloads the data from these peers in parts and
`in parallel. Retrieving the content as previously cached with multiple peers
`potentially speeds up the web transfer and reduces traffic with web servers. Id.,
`15:13-52.
`The preferred operation is for requesting clients to obtain as much of the
`desired content as feasible from peer caches. See id.
`However, all requested content still must come from its actual origin. If an
`agent determines that the content request cannot be satisfied from peer caches,
`processing reverts to a model, more pertinent to the claimed embodiments, in
`which the agent serves as a retrieval intermediary, as shown in Fig. 3 of the
`’319 patent: in this scenario (i.e., no cache hit among the connected peers),
`the agent makes a request directly to the web server for the content, and after
`the web server sends the data, the agent responds to the requesting client,
`listing itself as the only peer with responsive data, and then, acting as that peer,
`transfers the responsive data to the requesting client upon the latter’s request

`
`(id., 14:62-15:11), thus implementing at a high level the characteristic proxy
`server data flow first shown above.2
`
`4.3. Priority Date
`
`The ’319 patent claims priority to provisional application 61/249,624 (the
`“2009 Provisional”) filed on October 8, 2009 (“Priority Date”). (The claimed
`priority pre-dates the March 16, 2013 effective date of the First Inventor to File
`provisions of the AIA.)
`
`5. LEVEL OF SKILL IN THE ART
`
`A person of ordinary skill in the art (“POSITA”) in the field to which
`the ’319 patent pertains would have at least a bachelor’s degree in Computer
`Science or related field (or equivalent experience), and two or more years’
`experience working with and programming networked computer systems as
`of the Priority Date. Such a person would be familiar with the underlying
`principles of Web, Internet, or network communication, data transfer, and
`content s
