DEFENDANT GOOGLE INC.’S THIRD SUPPLEMENTAL OBJECTIONS AND
RESPONSES TO PLAINTIFF I/P ENGINE, INC.’S FIRST SET OF
INTERROGATORIES (INTERROGATORY NO. 8)
Pursuant to Federal Rules of Civil Procedure 26 and 33, Defendant Google Inc.
(“Google”) hereby further objects and responds in writing to I/P Engine, Inc.’s (“I/P Engine”)
First Set of Interrogatories as served on November 7, 2011.
GENERAL OBJECTIONS
Google hereby incorporates by reference and re-states each General Objection from
Google’s First and Second Supplemental Objections and Responses to I/P Engine’s First Set of
Interrogatories.
STATEMENT ON SUPPLEMENTATION
Google’s investigation in this action is ongoing, and Google reserves the right to rely on
and introduce information in addition to any information provided herein at the trial of this
matter or in other related proceedings. Google has yet to receive complete discovery responses
from I/P Engine. In addition, I/P Engine has yet to identify in a coherent way how it contends
Google infringes the asserted claims of the Patents-in-Suit. Google anticipates that facts it learns
01980.52020/4832162.1

later in the litigation may be responsive to one or more of the interrogatories and Google reserves
is right to supplement these interrogatories at appropriate points throughout this litigation
without prejudice and/or to otherwise make available to I/P Engine such information. Google
also reserves the right to change, modify or enlarge the following responses based on additional
information, further analysis, and/or in light of events in the litigation such as rulings by the
Court. Google reserves the right to rely on or otherwise use any such amended response for
future discovery, trial or otherwise.
SPECIFIC OBJECTIONS AND RESPONSES
Google expressly incorporates the above objections as though set forth fully in response
to each of the following individual interrogatories, and, to the extent that they are not raised in
the particular response, Google does not waive those objections.
INTERROGATORY NO. 8
Identify and describe each basis for Google’s contention that the claims of the ‘420 and
‘664 Patents are invalid including, but not limited to, all facts, dates, documents,
communications and/or events, including prior art, which Google contends are pertinent thereto,
and identify the persons having the most knowledge of such facts, dates, documents,
communications and/or events.
RESPONSE TO INTERROGATORY NO. 8:
Google incorporates here in response to this interrogatory its General Objections above
by this reference. Google objects to this interrogatory on the grounds that: (i) it is overbroad and
unduly burdensome; (ii) it is vague and ambiguous with respect to the phrase “all facts, dates,
documents, communications and/or events;” (iii) it seeks information that is irrelevant,
01980.52020/4832162.1
2
immaterial or not reasonably calculated to lead to the discovery of admissible evidence. Google
further objects to this interrogatory on the ground that it seeks proprietary, trade secret or other
confidential or competitively sensitive business information; and (iv) it is compound and/or is
comprised of subparts constituting more than one interrogatory in that it seeks information about
‘420 and ‘664 Patents. Google will only produce such relevant, non-privileged information
subject to adequate protections for Google’s confidential, trade secret and/or proprietary business
or technical information via a protective order entered by the Court in this action.
Subject to the foregoing general and specific objections, Google responds that in
accordance with Federal Rule of Civil Procedure 33(d), all or part of the non-objectionable
discovery sought may be obtained from documents that will be produced. Google will rely on
documents produced in this action and will identify those documents to the extent reasonable
after the time they are produced. Google will supplement its response to Interrogatory No. 8 to
reference relevant documents to the extent reasonable.
Google further responds that the following references, either alone or in conjunction with
the knowledge of one of skill in the art, render one or more of the asserted claims invalid:
“Content-Based, Collaborative Recommendation” by Balabanovic et al.
“Feature-based and Clique-based User Models for Movie Selection: A
Comparative Study” by Alspector et al.
“Using Collaborative Filtering to Weave an Information Tapestry” by Goldberg et
al.
“Architecting Personalized Delivery of Multimedia Information” by Loeb
U.S. Patent No. 5,794,237 to Gore
U.S. Patent No. 5,835,087 to Herz
U.S. Patent No. 5,855,015 to Shoham
U.S. Patent No. 6,202,058 to Rose

U.S. Patent No. 6,421,675 to Ryan et al.
U.S. Patent No. 5,963,940 to Liddy et al.
Google further asserts that the asserted claims of the ‘420 and ‘664 patent, as apparently
interpreted by Plaintiff, are invalid for lack of enablement and written description. In particular,
neither patent describes or enables using collaborative filtering or any other form of feedback on
a demand search. Rather, the patents only describe and enable using collaborative filtering with
persistent or “wire” search results.
Google reserves its right to supplement, revise or render more specific its responses to
Interrogatory No. 8, including during expert discovery.
SUPPLEMENTAL RESPONSE TO INTERROGATORY NO. 8:
Subject to the foregoing general and specific objections, Google identifies the following
documents previously produced by Google as showing that the asserted claims from the ‘420 and
‘664 patents are invalid: G-IPE-0217615 - G-IPE-0217641, G-IPE-0217642 - G-IPE-0217648,
G-IPE-0217649 - G-IPE-0217672, G-IPE-0217673 - G-IPE-0217683, G-IPE-0217684 - G-IPE0217693, G-IPE-0217694 - G-IPE-0217708, G-IPE-0217709 - G-IPE-0217756, G-IPE-0217757

Google served its Preliminary Invalidity Contentions on January 24, 2012. Google
hereby incorporates those Contentions by reference and submits that its response to this
01980.52020/4832162.1

and/or supplement its invalidity contentions if and when further information becomes available.
Google reserves its right to supplement, revise or render more specific its responses to
Interrogatory No. 8, including during expert discovery.
SECOND SUPPLEMENTAL RESPONSE TO INTERROGATORY NO. 8
Google incorporates its General Objections, Specific Objections to Interrogatory No. 8,
and prior responses to Interrogatory No. 8 as if fully set forth herein.
Subject to the foregoing General and Specific Objections, Google further states that the
following additional prior art references, either alone or in conjunction with the knowledge of one
of skill in the art, render one or more of the asserted claims invalid:
U.S. Patent No. 6,185,558 to Bowman et al. (“Bowman”)
U.S. Patent No. 6,006,222 to Culliss (“Culliss”)
U.S. Patent No. 6,421,675 to Ryan et al. (“Ryan”)
Claim charts illustrating how Bowman, Culliss, and Ryan invalidate the asserted claims
are attached hereto as Exhibits A-7, A-8, and A-9.1
Plaintiff alleged that various references from Defendants’ Preliminary Invalidity
Contentions do not filter informons “for relevance to the query” or receive information “found to
be relevant to the query by other users,” on the theory that these references filter and rank for
relevance to the user instead of relevance to the query. See, e.g., I/P Engine’s Response to
Google’s Interrogatory No. 13 at 6 (stating that the Rose reference “ranks items based on how

Google further attaches to this interrogatory response, as Exhibits A-1 through A-6,
amended versions of the claim charts that were first presented as Exhibits to Defendants’
Preliminary Invalidity Contentions.

well their content matches a profile of interests stored for each user, not a query received from an
individual user”); 14 (“Nor does Balabanovic disclose ‘receiving information found to be
relevant to the query by other users.’ Balabanovic’s feedback is an indication of how well a user
liked an item.”)
Defendants further provide invalidity charts for Bowman, Culliss, and Ryan, which filter
information “for relevance to the query” and “receiv[e] information found to be relevant to the
query by other users.” See Exhibits A-7, A-8, A-9. For example, Bowman accepts a search
query from a user and generates a body of search results that match the query. (See Bowman at
Abstract; 5:31-32; claim 28). Bowman then gives each search result a ranking score based on
how often prior users who had entered the same query had selected that particular result. (See id.
at Abstract; 2:30-35; 5:32-35; claim 28). Items that were selected more often get higher ranking
scores, and the items with the highest ranking scores are presented to the user. (Id. at 9:60-64).
(As detailed in the attached charts, Bowman, Culliss, and Ryan also use content-based filtering
with their feedback-based filtering.)
Notably, while I/P Engine sought to distinguish the prior art references on the alleged
ground that they do not filter information “for relevance to the query” or “receiv[e] information
found to be relevant to the query by other users,” it has essentially ignored these limitations in its
Infringement Contentions. For example, I/P Engine’s Infringement Contentions state that
Google AdWords meets the ‘664 claim element of “receiving information found to be relevant to
the query by other users” because AdWords allegedly records an advertisement’s historical clickthrough rate and allegedly uses this click-through rate as a component of the advertisement’s
Quality Score. (See I/P Engine, Inc.’s Second Preliminary Infringement Contentions against
Google at 24-25). Even if these assertions are true—and they are not—I/P Engine does not even
01980.52020/4832162.1
6
try to explain how historical click-through rate constitutes “information found to be relevant to
the query by other users.” Rather, I/P Engine’s Infringement Contentions assert that an
advertisement’s historical click-through rate is the overall rate that the ad was clicked on by all
AdWords users, not just users who had entered the same query. Thus, I/P Engine’s own
Infringement Contentions fail to even allege how AdWords meets the limitation that I/P Engine
asserts was missing from Defendants’ prior invalidity charts, i.e. a measure of how relevant users
found an advertisement to be for any given query.
* * *
Google also notes that the Court’s Markman Order of June 15, 2012 (Dkt. 171) held that
“scanning a network” means “looking for or examining items in a network” and “a scanning
system” means “a system used to search for information.” (See id. at 23). Under this
construction, the process of “scanning” is not limited to spidering or crawling, as Defendants had
originally proposed, expanding the relevant art for this element further. Similarly, the Markman
Order also construed “collaborative feedback data” and “[feedback system for] receiving
information found to be relevant to the query by other users” so as not to require that the
feedback or received information comes from users with similar interests or needs, again
expanding the art relevant to this limitation. (See id.) Google’s investigation continues as to
relevant prior art under the Court’s constructions and Google reserves its rights to supplement its
response based on additional prior art discovered under that investigation.
Further, the Court has construed “demand search” as “a single search engine query
performed upon a user request,” and has construed “query” as a “request for search results.”
(Markman Order at 8, 23). The Court construed “scanning a network” as “looking for or
examining items in a network.” (Id. at 23). Thus, the element of “scanning a network to make a
01980.52020/4832162.1
7
demand search for informons” requires looking for or examining items to make a request for
search results, which makes no sense. The ‘420 specification also does not describe how to look
for or examine items to make a request for search results, nor does it enable one of skill in the art
to carry out this step. Accordingly, claims 10, 25, and their dependents are invalid for
indefiniteness, lack of written description, and lack of enablement.
Google understands that I/P Engine will supplement its Infringement Contentions by July
2, 2012, and Google reserves its rights to supplement this response based on I/P Engine’s
forthcoming supplemental Infringement Contentions.

Exhibit A-8
U.S. Patent Claim Charts for the asserted ‘664 and ‘420 patents against U.S. Patent No. 6,006,222 (“Culliss”)
To the extent that either I/P Engine argues or the Court finds that this reference does not explicitly teach certain limitations in
the asserted claims, such limitations would have been inherent and/or obvious. This invalidity chart is based in whole or in part on
Defendants’ present understanding of the asserted claims, and I/P Engine’s apparent construction of the claims in their Infringement
Contentions. Defendants are not adopting I/P Engine’s claim construction, nor admitting to the accuracy of any particular claim
construction. To the extent that I/P Engine’s apparent claim construction or applications thereof are reflected in this invalidity chart,
nothing herein should be construed as an admission that Defendants agree with I/P Engine’s apparent claim construction or I/P
Engine’s application of that claim construction in its Infringement Contentions.
Defendants identification of this publication as prior art herein under 35 U.S.C. §§102(a), (b), (e), and/or (g) and §103 includes
the publication itself as well as the use of the products and systems described therein. Although Defendants’ investigation continues,
information available to date indicates that such products and systems were (1) known or used in the country before the alleged
invention of the claimed subject matter of the asserted claims, (2) were in public use and/or on sale in this country more than one year
before the filing date of the patent, and/or (3) were invented by another who did not abandon, suppress, or conceal, before the alleged
invention of the claimed subject matter of the asserted claim. Upon information and belief, these prior art products and systems and
their associated references anticipate and/or render obvious each of the asserted claims.
Defendants reserve all rights to amend their Invalidity Contentions if I/P Engine amends its Infringement Contentions.

Culliss at Abstract (“As users enter search queries and select articles, the
scores are altered”)
Culliss at 4:32-34 (disclosing that Culliss passively monitors whether the user
performs such selection actions as “opening, retrieving, reading, viewing,
listening to or otherwise closely inspecting the article.”)
"Once the user has selected a matched article, and as shown in FIG. 1 at 40,
the index can be altered such that the key term scores for the selected matched
article under the matched key terms are altered relative to other key term
scores." Culliss at 4:37-41.
