`
`C. THE ’045 PATENT (EX. 1001)
`
`The ’045 patent is directed to a system for storing information on a
`
`computer network and allowing the information to be accessed by terminals
`
`connected to the computer network, either directly, or through an
`
`intermediary device such as a local or proxy server. Ex. 1001, Abstract.
`
`The system includes computers or web sites that store pages, which may
`
`include references to banners to be displayed in conjunction with the web

`
`
`
`pages on the terminal. Id. The ’045 patent also discloses a method that
`
`“solves the initial problem of how to create accurate counts of banner
`
`information displays on user terminals while avoiding the problems created
`
`by requiring the banner information to be retransmitted across the computer
`
`network each time the banner information is requested by a user or a user’s
`
`terminal.” Id. at 14:3340. In one embodiment, the ’045 patent describes
`
`the use of an initial banner request signal that is a general content Uniform
`
`Resource Locator (“URL”) address generated by the terminal, where the
`
`URL does not specify which banner is to be displayed. Id. at 17:2226. The
`
`recipient of the initial banner request signal selects which banner is to be
`
`displayed on the terminal, and returns a specific content URL address to the
`
`terminal, using a “Status HTTP 302 Redirect signal,” indicating the address
`
`of the selected banner. Id. at 17:2636. Therefore, even though the banner
`
`may be cached or stored on the user’s terminal or on a proxy server, the
`
`specific content URL address signal is not cached, preventing the initial
`
`banner request signal from being blocked by either the terminal or the proxy
`
`server. Id. at 17:4250.
`
`D. ILLUSTRATIVE CLAIMS
`
`Challenged claims 1 and 34 are independent, and are reproduced
`
`below.
`
`1. A method for storing information on a primary server and one or
`more secondary servers and on computer sites connected to a computer
`network, wherein information delivered over the computer network to a
`terminal or a group of terminals may contain references to other information
`to be delivered to the terminal, comprising:
`
`4
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`serving a first portion of information to a terminal, wherein said first
`portion of information contains a reference to a second portion of
`information;
`causing a first request signal to be transmitted from the terminal to a
`primary server requesting a location address for said second portion of
`information from which said second portion of information can be served to
`the terminal, wherein said first request signal includes information intended
`to prevent said first request signal from being blocked from reaching said
`primary server by either the terminal or any intermediary device located
`topologically between the terminal and the primary server as a result of
`previous caching of said first portion of information or said second portion
`of information in the terminal or said intermediary device;
`sending a location signal from the primary server to the terminal
`providing said location address of said second portion of information;
`causing a second request signal to be transmitted from the terminal
`containing said location address of said second portion of information and
`requesting said second portion of information be served to the terminal; and
`serving said second portion of information to the terminal.
`
`34. A method for enabling a web page and an associated banner to be
`served to a computer, wherein the web page contains a link or other
`reference to the banner, comprising:
`serving a web page to a computer;
`causing a banner request signal to be sent from the computer to a
`primary server requesting a banner be served to the computer, wherein said
`banner request signal includes a Uniform Resource Locator address for said
`primary server and wherein said banner request signal includes information
`intended to prevent said banner request signal from being blocked from
`being received by the primary server as a result of previous caching of the
`banner on the computer;
`determining which specified banner will be served to the computer;
`
`and
`
`sending a banner location signal from said primary server to the
`computer, wherein said banner location signal includes the Uniform
`Resource Locator address for a device on which the specific banner to be
`served to the computer is stored.

`
`
`
`II. ANALYSIS
`
`A. CLAIM INTERPRETATION
`
`The Board interprets claims using the “broadest reasonable
`
`construction in light of the specification of the patent in which [they]
`
`appear[].” 37 C.F.R. § 42.100(b). We presume that claim terms have their
`
`ordinary and customary meaning. See In re Translogic Tech., Inc., 504 F.3d
`
`1249, 1257 (Fed. Cir. 2007) (“The ordinary and customary meaning ‘is the
`
`meaning that the term would have to a person of ordinary skill in the art in
`
`question.’” (citation omitted)).
`
`Petitioner and Patent Owner have proposed constructions for various
`
`terms. See Pet. 1216; Prelim. Resp. 1519. We do not need to construe
`
`every term proposed by the parties if the construction is not helpful in our
`
`determination of whether to institute trial. The scope of the claim term
`
`“banner” is determinative of whether we institute certain asserted grounds.
`
`Our discussion of this term follows.
`
`“banner”
`
`Both parties agree that “banner” means “information displayed in
`
`conjunction with a web page.” Pet. 12; Prelim. Resp. 15. The parties
`
`disagree, however, on whether additional explanations should be included in
`
`the definition. For example, Petitioner asserts that the information “is not
`
`part of the same file as the web page” (Pet. 12) while Patent Owner asserts
`
`that the information “can exist separately from the web page or which can be
`
`used in conjunction with many web pages” (Prelim. Resp. 15). Both parties
`
`rely on different portions of the specification to support their respective
`
`6
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`proposed constructions. Two issues are thus presented: (1) does the
`
`specification provide an express definition of the term as alleged by
`
`Petitioner; and (2) does the specification support a construction broader than
`
`Petitioner argues. These issues arise because the specification states that
`
`for purposes of the present invention, the term ‘banner’ is
`meant to be construed very broadly and includes any
`information displayed in conjunction with a web page
`wherein the information is not part of the same file as the
`web page. That is, a banner includes anything that is
`displayed or used in conjunction with a web page, but
`which can exist separately from the web page or which
`can be used in conjunction with many web pages.
`Banners can include graphics, textual information, video,
`audio, animation, and links to other computer sites, web
`sites, web pages, or banners.
`
`Ex. 1001, 2:2837. Patent Owner points to additional statements in the
`
`specification where the banner information may be served with the web
`
`page. See Prelim. Resp. 1516 (citing Ex. 1001, 10:2326 (“banner
`
`information may be served with the webpage or, more commonly, the
`
`banner information may reside in separate files.”)).
`
`We agree with the parties that the specification provides a description
`
`of a “banner” as information displayed in conjunction with a web page. But
`
`it is unnecessary for us to decide whether a banner may comprise
`
`information that may be part of the “same file as the web page” or served
`
`with the web page. The specification states the intent of construing “banner”
`
`with a stated, broad definition, and, therefore, we may not limit the
`
`construction of “banner” to how it may be served or stored vis-à-vis a web
`
`page. The claims provide sufficient detail regarding the location and
`
`7
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`operation of the banner such that we do not need to define the term further
`
`than how the information is displayed. Accordingly, under the broadest
`
`reasonable interpretation in light of the specification, for purposes of this
`
`Decision, we construe “banner” to mean “information displayed in
`
`conjunction with a web page.”
`
`B. OBVIOUSNESS GROUNDS BASED ON ANGLES, MERRIMAN,
`GARLAND, AND DAVIS
`
`Petitioner asserts four grounds predicated on, at a minimum, the
`
`combination of Angles and Merriman.
`
`1. Overview of Angles (Ex. 1012)
`
`Angles describes a system and method for delivering customized
`
`electronic advertisements in an interactive communication system. Ex.
`
`1012, Abstract. Angles’s system interconnects multiple consumer
`
`computers, multiple content provider computers, and multiple Internet
`
`provider computers with an advertisement provider computer. Id. Figure 4,
`
`reproduced below, illustrates Angles’s system, and shows the flow of
`
`information among these computers. See id. at 4:61:65.
`
`8
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`
`
`Figure 4 depicts content provider computer 14 that includes electronic
`
`pages 32 for presenting information to the consumer. See id. at 12:5160.
`
`Each electronic page 32 contains advertising insert 56 which is a place-
`
`holder configured to contain customized advertisement 30 generated by
`
`advertisement provider computer 18. Id. Advertising insert 56 contains
`
`advertisement request 26, which references a content provider Common
`
`Gateway Interface (CGI) script 64 that exists on advertisement provider
`
`computer 18. Id. at 13:14. “When the advertisement provider computer 18
`
`executes the content provider script 64, the advertisement provider computer
`
`18 identifies which content provider computer 14 is being accessed by a
`
`consumer computer 12.” Id. at 13:1619. Advertisement provider computer
`
`9
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`18 sends customized advertisement 30 to consumer computer 12. Id. at
`
`8:5661. Electronic page 32 and customized advertisement 30 are combined
`
`into a displayable page. Id. at 8:6265.
`
`Angles further describes an embodiment in which consumer computer
`
`12 includes advertising storage medium 44, which can be a compact disk
`
`drive and a compact disk, to store a variety of advertisements that can be
`
`retrieved and displayed by consumer computer 12. Id. at 11:5055. In this
`
`embodiment, the advertisement command identifies a particular location on
`
`advertising storage medium 44, such as the particular track and sector where
`
`an advertisement is located. Id. at 11:6612:2.
`
`2. Overview of Merriman (Ex. 1013)
`
`Merriman describes targeting the delivery of advertisements over a
`
`network, such as the Internet. Ex. 1013, Abstract. Figure 1, reproduced
`
`below, illustrates affiliate’s web site 12, advertisement (“ad”) server web
`
`site 19, and advertiser’s web site 18. See id. at 2:5962.
`
`10
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`
`
`In Figure 1, above, a user operates a web browser to generate
`
`request 20 directed to affiliate web site 12. Id. at 3:2428. The affiliate web
`
`site sends messages 22 containing the information available at the particular
`
`web site 12 for the requested page to be displayed by user browser 16,
`
`except for one or more advertising objects such as banner advertisements.
`
`Id. at 3:3034. Instead of sending the advertising objects, affiliate web
`
`server sends a link to the node running advertiser server process 19, where
`
`the link refers to an inline image, such as a banner. Id. at 3:3441. User
`
`browser 16 sends message 23 to advertising server process 19 to access the
`
`object. Id. at 3:4152. Upon receiving message 23, advertising server
`
`process 19 determines which advertisement or other object to provide to user
`
`browser 16 and transmits message 24 containing the object. Id. at 3:5257.
`
`The advertisement object then is displayed “as a composite of the received
`
`11
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`affiliate’s web page plus the object transmitted back by the advertising web
`
`server.” Id. at 3:5963. “As part of the ‘click through’ process, when the
`
`user clicks on the banner or other advertising object displayed by the user’s
`
`browser 16, the user’s browser again transmits a message [23] to the ad
`
`server.” Id. at 3:6467. Advertising server 19 notes the address of the
`
`computer that generated message 23 and transmits back the URL of the
`
`advertiser’s web page so that user browser 16 can generate a message 26 to
`
`contact advertiser web site 18. Id. at 3:674:5.
`
`3. Overview of Garland (Ex. 1009)
`
`Garland describes an architecture and protocol for a distributed web
`
`server group, as illustrated in Figure 5, reproduced below. Ex. 1009, 3.
`
`Figure 5, above, illustrates a web client sending an HTTP request and
`
`a dispatcher server that calculates the least-loaded server and sends the
`
`forwarding address of that server. Id. at 3. The dispatcher distributes the
`
`requests to balance the load placed on the member servers. Id. at 5.
`
`
`
`12
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`4. Discussion
`
`Petitioner contends that Angles discloses most of the limitations of
`
`independent claims 1 and 34. Pet. 18–25. In particular, Petitioner contends
`
`that Angles’s advertisement request, which references a CGI script, discloses
`
`the “first request signal includ[ing] information intended to prevent said first
`
`request signal from being blocked from reaching said primary server . . . as a
`
`result of previous caching,” recited in claim 1, and the “banner request
`
`signal include[ing] information intended to prevent said banner request
`
`signal from being blocked from being received by the primary server as a
`
`result of previous caching,” recited in claim 34. We are not persuaded that
`
`Petitioner has made a sufficient showing that Angles discloses the recited
`
`signals. Although Petitioner alleges that a person of ordinary skill in the art
`
`would recognize that referencing a CGI script in the advertisement request
`
`would not be blocked (Pet. 20), the Petition neither mentions nor points to
`
`evidence that Angles’s system includes a cache. See Prelim. Resp. 21
`
`(arguing that Angles contains no reference whatsoever to a cache). The
`
`significance of the omission is such that we are not able to determine
`
`whether Angles’s advertisement request is employed to avoid a cache where
`
`information previously was cached. Specifically, the claims require that the
`
`above-identified signals include information “intended to prevent” said
`
`signal from being blocked “as a result of previous caching.” If Angles is not
`
`shown or argued to disclose, teach, or suggest caching, we cannot determine
`
`that the reference to the CGI script in the advertisement request is intended
`
`to prevent blocking as a result of previous caching.
`
`13
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`Accordingly, we are not persuaded that Petitioner has shown a
`
`
`
`
`
`reasonable likelihood that claims 1 and 34 would have been obvious over
`
`Angles and Merriman. Petitioner does not allege that any of the other
`
`references disclose, teach, or suggest the information intended to prevent
`
`blocking as a result of previous caching as recited in claims 1 and 34. Nor
`
`does Petitioner allege that any other reference teaches or suggests caching
`
`such that a person of ordinary skill in the art would have found it obvious for
`
`Angles to use caching and to prevent blocking as a result of previous
`
`caching. Therefore, Petitioner has failed to show a reasonable likelihood
`
`that claims 212 and 1419, which depend from claim 1, and claims 3342,
`
`which depend from claim 34, are unpatentable as obvious over combinations
`
`involving Angles, Merriman, Garland, and Davis. Consequently, no trial is
`
`instituted on any of those grounds.
`
`C. OBVIOUSNESS GROUNDS BASED ON WEXLER, HTTP1.0,
`MEEKER, AND GARLAND
`
`Petitioner asserts three grounds predicated on, at a minimum, the
`
`combination of Wexler and HTTP1.0.
`
`1. Overview of Wexler (Ex. 1007)
`
`Wexler is directed to providing on-line third party accounting and
`
`statistical information. Ex. 1007, Abstract. A third party accounting service
`
`receives download request signals intended for an advertiser Web site. Id.
`
`The download request signal results from a user clicking on a banner
`
`displayed on a Web page, because the banner is configured to point to the
`
`third party Web site, rather than pointing to the advertiser’s Web site. Id.
`
`The third party Web site maintains a count of the received download request
`
`14
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`signals generated by clicking on the banner, and sends a redirect signal to
`
`the user’s Web browser causing the advertiser Web site to send the
`
`information originally sought by the user. Id.
`
`2. Overview of HTTP1.0 (Ex. 1008)
`
`HTTP1.0 is a working document of the Hypertext Transfer Protocol
`
`(HTTP) Working Group. Ex. 1008, 1. The document describes
`
`specifications for the protocol referred to as “HTTP/1.0.” Id. In particular,
`
`HTTP1.0 discloses the use of a “Pragma general-header field.” Id. at 35.
`
`“All pragma directives specify optional behavior from the viewpoint of the
`
`protocol; however, some systems may require that behavior be consistent
`
`with the directives.” Id. One pragma directive is a “no-cache” directive,
`
`which is described as follows:
`
`When the "no-cache" directive is present in a request
`message, an application should forward the request
`toward the origin server even if it has a cached copy of
`what is being requested. This allows a client to insist
`upon receiving an authoritative response to its request.
`It also allows a client to refresh a cached copy which is
`known to be corrupted or stale.
`Id. at 3536.
`
`3. Discussion
`
`Wexler describes a third party accounting and statistical service that
`
`redirects a user’s web browser to request a web page from an advertiser after
`
`the user clicks on a banner. Ex. 1007, 2:38–56. Petitioner relies on
`
`Wexler’s advertiser’s web page as disclosing the “second portion of
`
`information” (claim 1) and “banner” (claim 34). Pet. 43. That is, although
`
`Wexler discloses banner 9 displayed with web page 7, Petitioner alleges that
`
`15
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`the claimed “banner” is, instead, the web page displayed after the user clicks
`
`on banner 9. Id. Patent Owner has challenged this assertion as insufficient
`
`to show unpatentability of claims 1 and 34.
`
`According to Patent Owner, the advertiser’s web page is not a
`
`“banner,” and Wexler does not disclose two requests to retrieve a banner.
`
`Prelim. Resp. 40–44. This argument is not commensurate with claim 1,
`
`which does not recite a “banner.” Nevertheless, with regard to claim 34, we
`
`agree with Patent Owner that the two separate web pages served in Wexler
`
`are not a web page and a banner within the scope of claim 34. Particularly,
`
`we have construed “banner” to require, at a minimum, that the information is
`
`displayed in conjunction with a web page. Notwithstanding the conclusory
`
`assertion of the Kent Declaration at paragraph 158, two web pages are not
`
`displayed in conjunction with each other, they are displayed separately. One
`
`web page is displayed first, the advertiser’s web page is displayed
`
`separately, and only after the user has clicked through the banner’s
`
`advertisement. Therefore, Wexler’s advertiser’s web page is not a “banner”
`
`that is displayed in conjunction with a web page. The Kent Declaration is
`
`conclusory on this point, particularly on the assertion that a web page would
`
`have been displayed in a frame or an iframe within another web page. See
`
`Ex. 1003 ¶ 158. There is insufficient factual support for this assertion,
`
`especially in light of Patent Owner’s argument (and evidence) that such
`
`features were not in existence in the HTML specification until after the time
`
`of the invention. See Prelim. Resp. 43 (citing Ex. 2011). Accordingly, we
`
`are persuaded by Patent Owner’s argument that Petitioner’s contentions of
`
`16
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`unpatentability with regard to claim 34 are insufficient to institute inter
`
`partes review.
`
`With regard to the combination of Wexler and HTTP1.0 (asserted in
`
`connection with claims 1 and 34), we also are persuaded by Patent Owner’s
`
`arguments that the evidence of a motivation to combine the references is
`
`insufficient. Petitioner alleges that Wexler’s request 15a may be modified to
`
`include a pragma: no-cache directive such that the request will be rendered
`
`“unblockable.” Pet. 44. Using a no-cache directive in a request, according
`
`to Patent Owner, however, has not been shown to be a standard feature in a
`
`browser or a known technique applicable to a request made by a user when
`
`clicking on a hyperlink. See Prelim. Resp. 4546. The HTTP1.0 reference
`
`proffered by Petitioner is generic in its description of the pragma directives,
`
`and confirms that that they specify optional behavior from the viewpoint of
`
`the protocol. Ex. 1008, 35. Petitioner does not point to anything indicating
`
`that Wexler implemented pragma directives or that its system requires
`
`compliance with this optional protocol parameter. Furthermore, Patent
`
`Owner has argued persuasively (and provided supporting evidence) that a
`
`no-cache directive in Wexler’s request 15a requires explanation, because at
`
`the time of the invention, it was not known for a server to cause a browser to
`
`use such a directive in connection with a banner request, such as that of
`
`Wexler. See Prelim. Resp. 45 (arguing that the ’045 patent does not suggest
`
`including a Pragma: no-cache directive in a banner request because there
`
`was no apparent way for a server to cause a browser to do so). Finally, we
`
`note that Petitioner relies expressly in the disclosure of the ’045 patent to
`
`support the argument that the Pragma no-cache directive was known to be an
`
`17
`
`
`
`
`
`IPR2015-00658
`Patent 6,286,045 B1
`
`
`
`“unblockable” signal. Pet. 44. As Patent Owner points out, though, the
`
`specification of the ’045 patent references a “pragma:no-cache tag” used in
`
`an HTTP 302 Redirect signal to a receiver, not in a request sent from a
`
`receiver. See Ex. 1001, col. 18, ll. 14–17; Prelim. Resp. 45.
`
`Accordingly, we are not persuaded that Petitioner has shown a
`
`reasonable likelihood of prevailing in its contention that claims 1 and 34 are
`
`unpatentable as obvious over Wexler and HTTP1.0. Petitioner does not
`
`assert either Meeker or Garland as making up for the deficiencies noted
`
`above. Therefore, we determine that Petitioner has not shown a reasonable
`
`likelihood of prevailing in its contention that claims 212, 1419, and 3542
`
`are unpatentable over the Wexler-based grounds.
`
`III. CONCLUSION
`
`For the foregoing reasons, we do not institute inter partes review of
`
`the ’045 patent in this proceeding.
`
`IV. ORDER
`
`After due consideration of the record before us, it is
`
`ORDERED that the Petition is denied and no trial is instituted.
