`
`Introduction
`
`Pursuant to 35 U.S.C. § 313 and 37 C.F.R. § 42.107, Richard A.
`
`Williamson, on behalf of and as Trustee for At Home Bondholders’ Liquidating
`
`Trust (“Williamson” or “Patent Owner”) hereby submits his Preliminary Response
`
`to the Petition for Inter Partes Review of U.S. Patent No. 6,014,698 (“698 Patent”)
`
`(GOOG 1001), (“Petition,” Paper 2) filed on February 2, 2015 by Google Inc.
`
`(“Petitioner”).
`
`On February 2, 2015, Petitioner filed five petitions for Inter Partes Review
`
`against the 698 Patent and a related patent, U.S. Patent No. 6,286,045 (“045
`
`Patent”). This Petition seeks cancelation of claims 17-20, 22-31, 34-39, 41-47, and
`
`49 of the 698 Patent on three different obviousness grounds. In this preliminary
`
`response, Williamson respectfully requests that the Board decline to institute Inter
`
`Partes Review of the 698 Patent because the obviousness combinations identified
`
`by the Petitioner do not contain all of the claimed elements and a person of
`
`ordinary skill in the art (“POSA”) would not have modified the identified
`
`references in a way that would result in the claimed invention.
`
`A.
`
`Summary of the 698 Patent
`
`The 698 Patent was filed June 11, 1997, by MatchLogic, Inc. and describes
`
`and claims a new way to serve banners for display in conjunction with web pages.
`
`–1–
`
`
`
`Patent Owner’s Preliminary Response
`IPR2015-00666 (U.S. Patent No. 6,014,698)
`Many web pages are configured to include banner advertisements, as shown in
`
`Figure 2 of the 698 Patent at 62, 64 and 66. (GOOG 1001 at 6:10-17).
`
`Web pages and associated banners are frequently cached by web browsers
`
`and by intermediate caching devices such as proxy servers, so that if a web page or
`
`advertising banner is requested again, the request will be satisfied from the cache
`
`without reconnecting to the servers from which the web page or banner was
`
`originally served. This reduces the load on the network and the time needed to
`
`display the web page.
`
`Unfortunately, caching made it difficult for advertisers to count how many
`
`times advertisements were displayed on users’ computers:
`
`Since the web page, and the banners to be displayed with the web
`page, selected by the user can be stored in either the user's terminal or
`the proxy server connected to the user's terminal, not all requests for
`the banner information are forwarded by the user's terminal or
`respective proxy server and transmitted over the computer network
`30. While this result may appear to be beneficial in that the amount of
`data traffic on the computer network 30 is reduced, in fact, this result
`prevents the accurate count of banner displays.
`
`(GOOG 1001 at 13:5-14).
`
`The 698 Patent explains that techniques were available to prevent caching,
`
`but preventing caching caused other significant problems:
`
`–2–
`
`
`
`Patent Owner’s Preliminary Response
`IPR2015-00666 (U.S. Patent No. 6,014,698)
`One solution to the problem is to prevent banner information from
`being stored or cached on either the user's terminal or the proxy server
`to which the user's terminal is attached…. For example, the HTTP
`and HTML protocols allow banners to be tagged or indicated as being
`uncachable…..[This solution] creates a significant problem, however,
`that creates even more significant consequences, thereby making its
`use for accurately counting advertisement and banner displays highly
`impractical and undesirable. More specifically, the storage of web
`pages and banner information at the user's terminal or in the proxy
`server conn[ect]ed to the user's terminal provides several important
`benefits that will be eliminated by this simple solution.
`
`(GOOG 1001 at 13:40-66).
`
`The invention disclosed and claimed in the 698 Patent solves the problem of
`
`accurately counting banner displays on users’ terminals while avoiding the
`
`problems created by requiring the banner information to be retransmitted across the
`
`network each time the banner is requested by a user's terminal. (Id. at 14:45-51).
`
`The invention uses a first request signal containing information intended to prevent
`
`the signal from being blocked by a caching device. Instead of responding to the
`
`first banner request signal with the banner, the claimed invention responds with a
`
`banner signal indicating the location of the banner on a server. The user’s
`
`computer then requests the banner in response to the banner location signal. Claim
`
`1 recites:

`
`
`
`Patent Owner’s Preliminary Response
`IPR2015-00666 (U.S. Patent No. 6,014,698)
`1. A method for delivering information to a terminal connected to a
`computer network, wherein
`information delivered over
`the
`computer network from a primary server to the terminal contains
`references to other information to be delivered to the terminal from
`the primary server or from one or more other servers connected to
`the computer network, comprising:
`
`serving a first portion of information to the terminal, wherein said first
`portion of information contains a reference to a second portion of
`information;
`
`sending a first request signal from the terminal to the 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 cannot be
`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 or storing of
`said first portion of information or said second portion of
`information by 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; and
`
`determining if said second portion of information is already stored on
`the terminal and, if said second portion of information is not
`already stored on the terminal, sending a second request signal
`from the terminal containing said location address of said second
`portion of information and requesting that said second portion of
`
`–4–
`
`
`
`Patent Owner’s Preliminary Response
`IPR2015-00666 (U.S. Patent No. 6,014,698)
`information be served to the terminal for display on the terminal,
`and, if said second portion of information is already stored on the
`terminal, displaying said second portion of information on the
`terminal.
`
`(GOOG 1001 at 28:3-35).
`
`The first request signal should always be received by the server, because it
`
`includes information intended to prevent blocking by a cache. The display of the
`
`banner should therefore always be counted. The second request signal is a
`
`conventional request signal that may be satisfied from a cache.
`
`The first request signal and the location signal contain very little information
`
`compared to the banner. These signals thus impose a negligible burden on the
`
`network compared to transmitting the banner from the originating ad server to the
`
`requesting device:
`
`[T]he initial banner request signal and the banner location signal are
`both extremely small, often comprising no more than a single packet
`or one-hundred to two-hundred bytes. Therefore, the overhead created
`by the additional banner signal during the step 112 and the banner
`location signal during step 114 is negligible. More importantly, since
`the method 110 still allows the web pages and the banner information
`to be cached or stored in the terminals and proxy servers, there is no
`unnecessary retransmission of the web pages or banners from the
`computer or web sites or the information or ad servers to the terminals
`
`–5–
`
`
`
`Patent Owner’s Preliminary Response
`IPR2015-00666 (U.S. Patent No. 6,014,698)
`which would significantly increase the data traffic and overhead on
`the computer network 30.
`
`(GOOG 1001 at 21:3-15). The invention thus solves the counting problem without
`
`giving up the benefits of caching. (Id. at 15:42-16:10).
`
`B.
`The invention of the 698 Patent was acknowledged as a solution
`to a long-felt, but poorly understood, problem
`
`In a November 21, 1997 article about companies developing web caching
`
`appliances, the Wall Street Journal Interactive Edition noted that caching was
`
`essential to the growth of the web but a problem for on-line advertisers:
`
`Analysts say that a new era is dawning in which network caching will
`become an integral -- and ultimately invisible -- part of the Internet's
`infrastructure…. But as it stands, network caching also creates
`headaches for content providers and on-line advertisers, both of which
`are regarding new developments with some degree of nervousness….
`Since requests for information are intercepted by caches, content
`providers don't know the answers to basic questions about traffic to
`their sites…. The on-line industry has understood for some time that
`the problem exists, but estimates of its magnitude have varied. But
`earlier this year, MatchLogic Inc., a Louisville, Colo., provider of
`on-line advertising management services, conducted a study that
`appears to shed some light on the issue.
`
`(AHBLT-2001.001-.003). The Wall Street Journal then noted that some
`
`companies had attempted to solve the problem by marking pages “uncacheable,”
`
`but that made pages slower for users:
`
`–6–
`
`
`
`Patent Owner’s Preliminary Response
`IPR2015-00666 (U.S. Patent No. 6,014,698)
`Already, some sites' Webmasters mark their pages as "uncacheable" to
`perform an end-run around caches. That ensures that people get fresh
`material, but it also means slower response time, which surfers don't
`like. Meanwhile, some network administrators have countered with
`their own tricks to foil cache-busting, or have simply denied access to
`uncacheable sites.
`
`(AHBLT-2001.005).
`
`This problem was also recognized in an October 6, 1997 article in the New
`
`York Times, which explained that “[o]ne of the biggest fetters on the growth of
`
`advertising on the World Wide Web has been advertisers’ uncertainty about how
`
`many people are actually seeing the banners and other visual gadgets they are
`
`spending to promote.” (AHBLT-2002). The article explains that MatchLogic
`
`“plans to introduce software that it says will solve the problem, allowing accurate
`
`counts of how many people see a Web ad.” (Id.). The article noted that the
`
`software solution was backed by “a giant advertiser, General Motors, and the Audit
`
`Bureau of Circulations, which certifies the reliability of circulation figures of
`
`printed publications and now of Web sites.” (Id.).
`
`On October 13, 1997, the industry journal Advertising Age published an
`
`article entitled “Interactive: Media & Marketing: Matchlogic Service Solves Cache
`
`Problem.” (AHBLT-2003). In the article, Advertising Age noted that the Audit
`
`–7–
`
`
`
`Patent Owner’s Preliminary Response
`IPR2015-00666 (U.S. Patent No. 6,014,698)
`Bureau of Circulations1 had reviewed MatchLogic’s technology and found that it
`
`“raises the bar in terms of providing more complete activity reporting”:
`
`"This raises the bar in terms of providing more complete activity
`reporting" for online advertising, said Michael Lavery, president and
`managing director of the Audit Bureau of Circulations. "We have
`reviewed [TrueCount], and it works as [MatchLogic] says it does. . . .
`It allows for accounting of [online ad] activity heretofore not
`accounted [for]," he said.
`
`(AHBLT-2003.001 (brackets in original)). The article also quoted an analyst at
`
`Jupiter Communications who felt that MatchLogic’s technology had “vast”
`
`implications for the market:
`
`"The implications for the market are vast," said Evan Neufeld, an
`analyst at Jupiter Communications. He believes if TrueCount is
`widely adopted and if competitors like Focalink and Imgis implement
`similar technology, the cost-per-thousand rates of banners should
`drop.

` AHBLT-2004 (“The ABC founded in 1948 is a not for profit, voluntary
`organization consisting of Publishers, Advertisers and Advertising Agencies. It has
`done pioneering work in developing audit procedures to verify the circulation data
`published by those newspapers and periodicals which have earned the right to
`display its emblem.”).
`
`–8–
`
`
`
`Patent Owner’s Preliminary Response
`IPR2015-00666 (U.S. Patent No. 6,014,698)
`(AHBLT-2003.002). Like the Wall Street Journal, the Advertising Age article
`
`noted that caching had “long confounded commercial sites and advertisers” and
`
`that “cache-busting” techniques to simply prevent caching slowed delivery times
`
`and harmed the viability of the Web:
`
`Institutions with many Internet users, such as large companies,
`universities and Internet service providers, regularly use proxies to
`cache Web content from popular sites so their users don't download
`the same files repeatedly across the networks. While the caches
`improve bandwidth, they have long confounded commercial sites and
`advertisers, which lose control of both the targeting and counting of
`ads behind the proxy firewalls….
`
`Presently, many sites employ "cache-busting" techniques that force
`the delivery of ads and other content through the proxy servers for
`each user who requests a page. The down side of cache-busting,
`however, is it slows the delivery time for users, which harms the
`viability of the Web medium.
`
`(AHBLT-2003.001-.002). Advertising Age noted that MatchLogic’s solution
`
`“delivers the best of both worlds”:
`
`TrueCount - which MatchLogic built at the behest of its largest client,
`General Motors Corp. - delivers the best of both worlds.
`
`It works in harmony with proxy servers to help manage bandwidth
`while keeping control of the ads' distribution. Where possible, it
`serves ads out of the institution's local cache or from the nearest of
`TrueCount's 12 worldwide mirror sites. Thus, it not only counts the
`
`–9–

`total number of impressions shown behind proxies, but it continues to
`manage the ad frequency and other targeting issues to individual

`
`C. The invention of the 698 Patent was widely adopted by industry
`
`Seventeen months after MatchLogic filed the application for the 698 Patent,
`
`an engineer for a MatchLogic competitor, NetGravity, published a draft guideline
`
`that suggested using the invention of the 698 Patent. (AHBLT-2005). This
`
`“working draft” describes the invention of the 698 Patent in detail and thanks the
`
`inventor, Mike Griffiths. (Id. at .005).
`
`Several years later, in November 2004, the NetGravity proposal was adapted
`
`by the Internet Advertising Bureau into a set of guidelines for its members to
`
`follow. (AHBLT-2006). These members included Google, Doubleclick, AOL,
`
`Yahoo!, Accipiter, and NY Times Digital among others. (Id. at .004).
`
`Before the proposal was adapted into a set of guidelines, DoubleClick2
`
`adopted the invention of the 698 Patent by at least 2001 when it published a white
`
`paper describing its impression counting method. (AHBLT-2008). The white
`
`paper describes combining techniques to defeat caching including using “Random,
`
`
` DoubleClick was acquired by Petitioner Google in March of 2008. (AHBLT-
`2012)

`
`D.
`invalidity
`
`Petitioner’s declarations do not make a prima facie case of
`
`Petitioner submits two declarations in support of the 666 Petition. GOOG
`
`1005 is the declaration of Mr. Leach, a contributor to the HTTP 1.0 and HTTP 1.1
`
`specifications. GOOG 1003 is the declaration of Mr. Kent, an author of books on
`
`how to promote yourself on the Internet (Poor Richard's Internet Marketing and
`
`Promotions: How to Promote Yourself, Your Business, Your Ideas Online, GOOG
`
`1003, at ¶ 8); how to make money on the Internet (How to Make Money Online
`
`with eBay, Yahoo!, and Google, id.); and a professional “Internet Expert Witness”
`
`with a degree in Geography/Geology. (GOOG 1004, at 1, 5).
`
`Mr. Leach never expresses an opinion that the claimed invention was
`
`anticipated or obvious in his declaration. In fact, Mr. Leach is completely silent
`
`concerning the combination of a first request including information intended to
`
`prevent the request from being blocked due to caching, a location signal and a
`
`second request. Further, Mr. Leach’s declaration establishes that persons involved
`
`with development of the HTTP specification believed that caching posed a
`
`problem for advertising and considered schemes to disable caching a “’resource
`
`intensive solution.’” (GOOG 1005 at ¶25). It also establishes that the extent of
`
`–11–
`
`
`
`Patent Owner’s Preliminary Response
`IPR2015-00666 (U.S. Patent No. 6,014,698)
`their use was not well understood. (“'Cache-busting' is the use by servers of
`
`techniques intended to prevent caching of responses; it is unknown exactly how
`
`common this is.”) (Id. at ¶24 (emphasis added)).
`
`Mr. Leach’s declaration also shows that identifiers had previously been used
`
`in URLs to track visitors, but was considered a bad idea precisely because it
`
`defeated caching, and because it was computationally expensive and did not permit
`
`people to exchange URLs:
`
`As discussed at the International World Wide Web conference in
`April 1997, “[i]n the earlier days of the Web, the tracking of visitors
`was often accomplished by inserting identifiers into the URLs issued
`by the server and channeling all subsequent requests through a CGI
`script" and "[n]ot only was this method expensive computationally to
`the server, but it defeated intermediary caching and did not correctly
`handle the exchanging of URLs between people…These days, this
`form of identification is typically accomplished by setting the
`expiration of an issued cookie into the far future.”
`
`(Id. at ¶ 28), see also (GOOG 1023 at 2).
`
`Mr. Leach goes on to say that persons of ordinary skill in the art would have
`
`known that the HTTP 1.0 specification and HTTP 1.1 draft specification provided
`
`for headers (if-modified-since and if-not-match) that would prevent a request
`
`containing those headers from being blocked by a cache. However, Mr. Leach
`
`explains that requests containing these headers would either return the requested
`
`–12–
`
`
`
`Patent Owner’s Preliminary Response
`IPR2015-00666 (U.S. Patent No. 6,014,698)
`content or a 304 (not modified) response. Neither Mr. Leach nor the HTTP 1.0
`
`and 1.1 documents he cites suggest that a request containing these headers could
`
`return a location signal in response or that such a location signal would be
`
`advantageous. The understanding of those of skill in the art that the if-modified-
`
`since and if-not-match headers were better choices for preventing caching thus
`
`teaches away from the claimed invention.
`
`Mr. Leach also discusses a proposal he made with Jeffrey Mogul in 1997
`
`concerning “hit metering.” Mr. Leach explains that his “hit metering” approach
`
`did not use any of the “cache busting” techniques he discusses in his declaration.
`
`(Id. at ¶35). His hit metering proposal itself specifies a new “Meter” HTTP header
`
`to meet this goal. (GOOG 1024 at 4 §1.2). Neither Mr. Leach nor the Petitioner
`
`suggests that Mr. Leach’s hit metering proposal discloses or renders obvious any
`
`claim of the 698 Patent. This confirms that Mr. Leach himself was actively
`
`teaching the community of protocol designers in a direction away from the claimed
`
`invention of the 698 Patent.
`
`Mr. Leach’s declaration therefore shows that the knowledge of persons
`
`skilled in the art at the time of the invention taught away from the claimed
`
`combination of a banner request signal including information intended to prevent
`
`blocking by a cache with a banner location signal.

`Further, as explained below, Mr. Kent’s opinions and the Petition as a whole
`
`do not set forth a prima facie case of obviousness for any of the claims of the 698
`
`Patent. In order to sustain a successful petition for Inter Partes Review, Petitioner
`
`was required to provide “articulated reasoning with some rational underpinning to
`
`support the legal conclusion of obviousness.” Cisco Systems, Inc. v. C-Cation
`
`Techs, Inc., IPR2014-00454, Paper 12 at 13 (citing KSR Int’l Co. v. Teleflex Inc.,
`
`550 U.S. 398, 418 (2007) (quoting In re Khan, 441 F.3d 977, 998 (Fed. Cir.
`
`2006))). It did not. Petitioner’s and Mr. Kent’s statements—statements that are
`
`made throughout the Petition—of general principles from the case law that “a
`
`proposed combination ‘involves no more than a combination of known elements,’
`
`or that a proposed combination is ‘the predictable use of such elements according
`
`to their established functions,’ or that a proposed combination yields ‘predicable
`
`results’ are conclusions, they are not a substitute for a fact-based analysis of the
`
`proposed combination of references necessary to support those conclusions.”

`
`This is fatal to the Petition.

`
`Patent Owner’s claim constructions should be adopted

`The Patent Trial and Appeal Board interprets claims using the broadest
`
`reasonable construction in light of the specification of the patent in which it
`
`appears. 37 C.F.R. § 42.100(b). Petitioner has proposed specific constructions for

`
`and counter-proposal to each construction is provided below.
