UNITED STATES DISTRICT COURT
EASTERN DISTRICT OF VIRGINIA
I/P ENGINE, INC.
AOL, INC., et al.,
Civil Action No. 2:11-cv-512
REPLY BRIEF IN SUPPORT OF DEFENDANTS’ RENEWED MOTION FOR
JUDGMENT AS A MATTER OF LAW ON NON-INFRINGEMENT OR NEW TRIAL
As Defendants demonstrated in their motion, Plaintiff failed to provide sufficient
evidence to find that each of the Accused Systems meet all limitations of any asserted claim.
Rather than rebut Defendants’ actual argument, Plaintiff simply misconstrues the testimony of
both fact witnesses and experts. Plaintiff also continues to primarily rely on Google’s marketing
and high-level documents, despite admitting that these documents are irrelevant and that the best
source of evidence as to how the Accused Systems actually work is the source code. Given
Plaintiff’s failure to prove that the Accused Systems infringe, Defendants’ motion for judgment
as a matter of law on non-infringement, or in the alternative for a new trial, should be granted.
I/P ENGINE FAILS TO CITE ANY EVIDENCE THAT THE COLLABORATIVE
AND CONTENT LIMITATIONS WERE MET
I/P Engine Admits that the Accused Systems Do Not “Filter the Combined
Information” as Required by the ‘664 Patent.
In its opposition, I/P Engine does not dispute that the ‘664 Patent’s plain language
requires filtering of the “combined information.” (See ‘664 Patent, claims 1[c], 26[d].) Nor does
I/P Engine dispute that the claim language of the ‘664 Patent differs from the claim language of
claim 10[b] of the ‘420 Patent which requires “filtering the informons on the basis of applicable
content profile data for relevance to the query,”1 or that this shows the patentees were clear when
they intended the patents to require filtering something and when they required filtering on the
basis of something. (See ‘420 Patent, claim 10[b] (emph. added).)
While Plaintiff concludes that Dr. Frieder provided evidence that the “Accused Systems
filter the combined information” (Opp., 21), the evidence cited by I/P Engine actually
demonstrates that Dr. Frieder and I/P Engine failed to show that the Accused Systems filtered the
combined information. Plaintiff confirms that Dr. Frieder argued that “PCTR associated with a
particular ad is what is being used to filter out the ad. I’m filtering out ads using the pCTR.”
(Opp., 21 (emph. added).) But as detailed in Defendants’ motion, the claims required filtering
“the combined information,” not “using” what I/P Engine contends to be the combined
information to filter something else. There is no factual dispute, here, judgment as a matter of
law is appropriate. Fed. R. Civ. P. 50(a)(1).
While Plaintiff argues that this issue is “nothing more than differing opinions between
two experts” (Opp., 22), that is incorrect. Dr. Frieder simply ignored the plain language of the
claims when rendering his opinion.2 Here too, Defendants’ point is made by the testimony cited
by I/P Engine: “If you look at the Figure 6, it has the input coming in, the input as the two types
of input coming in, and the score computed, and then it filters based on that. That is exactly
I/P Engine’s argument in footnote 11 is nonsensical. Defendants do not agree that the
scope of the asserted claims of the ‘420 Patent include “filtering based on pCTR.” (Opp., 20
n.11.) I/P Engine’s theory is that the Accused Systems filter based on pCTR. Defendants deny
that this is correct, as seen by Section IV of their Motion. But even if Plaintiff were correct,
Defendants cannot infringe the ‘664 Patent under this theory because the ‘664 Patent requires
filtering “the combined information” not “based on” that information.
I/P Engine argues that Dr. Ungar’s interpretation excludes the preferred embodiment.
However, in the testimony cited by Plaintiff, Dr. Ungar does not admit that his interpretation of
“filtering the combined information” excludes a preferred embodiment of the ‘664 Patent or is in
any way inconsistent with the specification. Instead, the testimony cited to by Plaintiff relates to
the separate issue of what is “combining” information. (Trial Tr., 1400:18-1402:3.)
what the patent does.” (Opp., 21 (emph. added).) This testimony makes clear that Dr. Frieder
was improperly comparing the accused devices to a figure from the specification of the patent
and not to the asserted claims. Catalina Lighting, Inc. v. Lamps Plus, Inc., 295 F.3d 1277, 1286
(Fed. Cir. 2002) (“infringement is to be determined by comparing the asserted claim to the
accused device, not by comparing the accused device to the figures of the asserted patent.”).
The Accused Systems Do Not Combine “Content” and “Collaborative.”
I/P Engine fails to identify any evidence that the Accused Systems combine “content”
and “collaborative” analysis. Instead, in its Opposition, I/P Engine admits that under its
infringement theory “[c]ontent is placed into a string of values within the templates, that string of
value becomes the odds multiplier, and then the Accused Systems sum mathematically that data
to arrive at the pCTR.” (Opp., 24 (emph. added).) One thing becoming something else is not
combining the two. Rather, combining, by its nature, requires at least two different inputs—
otherwise there is nothing to combine.3
Here again, Plaintiff’s citation to Dr. Frieder’s testimony makes Defendants’ point.
Plaintiff cites Dr. Frieder’s testimony regarding Figure 6, which emphasizes that combining
requires multiple inputs: “[t]his combination function can be from a simple, weighted, additive
function to a far more complex neural network function.” (Trial Tr., 450:12-14 (referring to ‘420
Patent, 19:30-34).) Plaintiff’s infringement theory, however, uses one input, i.e., the alleged
content data or attribute value, to “lookup” another value, i.e., the alleged collaborative data or
odds multiplier. (Trial Tr., 694:5-19.) The Accused System then discards the alleged content
data or attribute value—it does not “filter” anything on the basis of that value.
This is consistent with the examples (originally cited by Defendants in their claim
construction brief) Plaintiff uses. (Opp., 23, n.12.) To make a high school curriculum, a person
would use at least two inputs, e.g., math and English. Similarly, to make an Indiana Jones
costume you would need at least a fedora and a bullwhip.
Dr. Frieder’s conclusory testimony that he is “combining it because I’m taking the two
sources and combining them,” does not provide sufficient evidence. (Id., 694:18-19.) See Kim
v. ConAgra Foods, Inc., 465 F.3d 1312, 1320 (Fed. Cir. 2006) (affirming JMOL of noninfringement where Plaintiff’s infringement theory was based solely on expert’s conclusory
testimony). Dr. Frieder does not provide any explanation or evidence to show how the attribute
values and the odds multipliers are combined. Rather, Dr. Frieder’s testimony shows the
opposite. His undisputed testimony is that the alleged content data is used to look up the alleged
collaborative feedback data. (Trial Tr., 694:11-13.)
Moreover, I/P Engine does not dispute that content and collaborative data are not
merged. Thus, regardless of whether the Court agrees that the claims require the merging of data
or just performing filtering using at least two different inputs, I/P Engine has failed to show that
the Accused Systems perform the requisite “combining.” Accordingly, I/P Engine has failed to
provide evidence that the Accused Systems “combine” the alleged content and feedback data.
The Accused Systems Do Not Perform Content-Based Filtering.
1. Claims require content-based “filtering.”
Plaintiff does not dispute that, as Defendants argued, the asserted claims require contentbased filtering, not just content-based analysis. (Br., 8.) In other words, filtering must be
performed based on the content of the data; mere analysis of the content of the data without
using the content data to filter is insufficient.4 While I/P Engine points to the use of feature
templates by the Accused Systems (Opp., 10), evidence of using feature templates is not
evidence of filtering, as no ads are discarded based on any feature template. At most, the use of
Comparing the “content-based filter[ing]” language used by the applicants against the
‘664 patents language of “filter[ing] the combined information” only further demonstrates that
the applicants were able to differentiate filtering based on something as opposed to filtering
something. See Chef America, Inc. v. Lamb-Weston, Inc., 358 F.3d 1371 (Fed. Cir. 2004).
feature templates would be content-analysis. (Id.) Indeed, this is what Plaintiff itself argues Dr.
Frieder said: “Dr. Frieder identified numerous feature templates in Google’s source code that
perform the required content analysis.” (Id. (emph. added).)
Plaintiff does argue that the Accused Systems filter based on the pCTR. (Opp., 21 (citing
Dr. Frieder (“I’m filtering out ads using the pCTR.”).) Plaintiff then attempts to argue that the
pCTR is the combination of content and collaborative feedback information. (Id., 24.) But even
if Google did filter on the basis of pCTR—which it does not (Br., 22-23)—that alleged filtering
cannot be both (1) filtering on the basis of the content data and (2) filtering on the basis of the
content data combined with the collaborative feedback data. In other words, the same alleged
“filtering” step cannot meet both filtering elements in the claims. Accordingly, the Accused
Systems either do not infringe because they do not meet the content-based filtering limitations,
or because they do not combine content and feedback information.
2. Plaintiff’s infringement theory contradicts its validity case.
As detailed in Defendants’ motion, Plaintiff’s infringement theory for content basedfiltering is inconsistent with its validity case. (Br., 8-9; see Trial Tr., 538:24-539:10, 674:11-14,
675:14-17, 692:9-13.) Dr. Carbonell sought to distinguish Culliss by arguing that using
attributes (which may include a comparison between the article and a keyword) to lookup
feedback data in the Culliss reference is not content-based filtering, the very thing Plaintiff
asserts meets the content filtering limitation in the Accused Systems. (Trial Tr., 1929:13-17;
1930:13-17.) Plaintiff attempts to distinguish the positions taken by Dr. Carbonell by arguing
that its infringement theory is based on “how well a query or keyword matches the content of an
advertisement,” not determining whether a query matches a keyword. (Opp., 15 (emph.
added).) This proves nothing. Dr. Carbonell himself testified that Culliss teaches the same
matching of keyword or “key terms” with content, here the content of an article, that Plaintiff
accuses. (Trial Tr., 1929:6-17 (“Q. Right, and those key terms come from words in the article in
our example, right? A. In the initialization step only. . . Q. Right. So the key terms are
associated with content in the article, correct? A. Yeah. We have been over this before. Yes.
There are other ways of doing it as well. This is one of the ways.”); DX-058 at 14:34-36 (“For
example, the scores can be initially set to correspond with the frequency of the term occurrence
in the article.”).) No reasonable jury could have found infringement in light of Plaintiff’s
experts’ testimony which offer opposite opinions over the same claim limitation. Amazon.com,
Inc. v. Barnesandnoble.com, Inc., 239 F.3d 1343, 1351 (Fed. Cir. 2001) (“A patent may not, like
a ‘nose of wax,’ be twisted one way to avoid anticipation and another to find infringement.”).
3. Plaintiff failed to provide any evidence of infringement for contentbased filtering for AdSense for Search, AdSense for Mobile Search,
QBB disabling and pre-2010 AdWords.
I/P Engine also fails to rebut its failure to demonstrate that all the Accused Systems
contain the feature templates I/P Engine contends show content based filtering. First, besides the
use of feature templates, I/P Engine has not identified any other content-based filtering in the
Accused Systems. Moreover, Plaintiff agrees that only some feature templates perform the
allegedly infringing content analysis. (Trial Tr., 694:24-695:2.) According to Dr. Frieder, these
few feature templates meet the content limitations of the asserted claims because they require a
“comparison” between the creative— i.e., the text of an ad— and the query. (Id., 529:17-20.)
Accordingly, to prove that the AdSense for Search, AdSense for Mobile Search, QBB Disabling,
and AdWords pre-2010 infringe the patents-in-suit, it was Plaintiff’s burden to provide evidence
that these systems included the alleged content-based feature templates, i.e. feature templates
that “compare” the creative and the query. Plaintiff never did.
Plaintiff attempts to remedy this failure of proof by arguing that these products are
“substantially the same.” But, again, Dr. Frieder admitted that these products use different sets
of feature templates.5 (See id., 544:4-7.) Plaintiff therefore cannot rely on feature templates in
AdWords to prove infringement in the other Accused Systems. Plaintiff could not point to any
specific feature or attribute which performs content-based analysis for any of the other Accused
Systems because Dr. Frieder’s expert reports contained no analysis of any feature templates in
AdSense for Search, AdSense for Mobile Search, or QBB disabling. I/P Engine has failed to
“clearly disclose, discuss, and identify” for the jury the supporting evidence they rely upon for
infringement, and so judgment as a matter of law should be granted. Fresenius USA, Inc. v.
Baxter Int’l, Inc., 582 F.3d 1288, 1300 (Fed. Cir. 2009).
There Was No Legally Sufficient Basis to Find That The Accused Systems
Use Collaborative Feedback Data.
1. Plaintiff did not provide evidence that the Accused Systems group
users with similar interests or needs.
Plaintiff accuses Defendants of “rehashing” “their failed claim construction arguments”
in asserting the collaborative feedback limitations were not met. (Opp., 16; see also id., 18-19.)
Not so. The Court adopted almost verbatim the construction of “collaborative feedback data”
proposed by Defendants: “data from system users with similar interests or needs regarding what
informons such users found to be relevant.” (D.N. 212, 4.) Plaintiff and its expert have
continually and repeatedly read out the requirement that collaborative feedback data refers to
The cited deposition testimony of Jonathan Alferness also explains “The closes[t]
analogy is really the AdSense for search product that we just talked about. So in general, things
operate very much the same way except again we are using a different and separate Smart Ads
model such that they’re trained for these properties in this mobile context.” (D.N. 755-1, 14-15,
¶ 10 (Oct. 17, 2012 (emph. added); see also id., 14, ¶ 9.) Moreover, in deposition testimony
played by Plaintiff in its case in chief, Mr. Hickernell, AOL’s 30(b)(6) witness, admitted that he
did not have any knowledge regarding the internal functionality of AOL Search Marketplace.
(See Declaration of Howard Chen in Support of Defendants’ Reply Briefs, Ex. 1, 46:14-47:1 (“I
don’t know anything inside of AdWords or AOL Search Marketplace.”).)
data from “users with similar interests or needs”. Plaintiff does so because there is no evidence
that the Accused Systems group users with similar interests or needs.
Rather than present evidence of “collaborative feedback” data, Plaintiff repeatedly argues
that the Accused Systems infringe because they use “feedback” data. For example, Plaintiff
argues that the Accused Systems “use click data related to queries run by users.” (Opp., 17; see
also id., 18.) Plaintiff points to click data, again relying on PX 338, a marketing document:6
PX 338 admits that the Accused Systems use “[y]our keyword’s past clickthrough rate (CTR): How often that keyword led to clicks on your ad.” PX 338 at
2 (emph added). This description actually repeats Dr. Frieder’s analysis. Dr.
Frieder testified that this feedback data satisfied the collaborative limitation of the
asserted claims. Trial Tr. at 489:2-10.
(Opp., 18.) But as Plaintiff admits, Dr. Frieder testified only about feedback data, reading out
the requirement that this be collaborative feedback data.
Citing Mr. Furrow’s testimony, Plaintiff also argues that “the Accused Systems are
‘taking what other people have done with similar interests…, storing it and then harvesting it as a
collaborative piece.” (Opp., 17-18.) But, Mr. Furrow did not testify at deposition or trial
regarding collaborative feedback data, or users with similar interests or needs. Instead, Mr.
Furrow simply testified that if a SmartAds attribute considers the query, then it trains using that
query. (Trial Tr., 1123:21-1124:4.)7 Mr. Furrow did not provide any testimony that AdWords
groups users with similar interests or needs. Nor did Mr. Furrow state that AdWords tracks how
This citation only illustrates Plaintiff’s continued improper reliance on marketing
Notably, Plaintiff points to attributes that track the query in attempting to prove that
the Accused Systems use collaborative feedback data. However, in attempting to prove that the
AdWords systems “combine” content feedback data and collaborative feedback data, Plaintiff
relies on odds multipliers that are associated with different attributes—ones that contain the
alleged “content” analysis. (Opp., 24.) Thus, even if Plaintiff was correct about the Accused
Systems using collaborative feedback data—which it is not—Plaintiff fails to show that this
“collaborative feedback data” is “combined” with the alleged content data even under its own
ads perform given a query. Rather, he testified that Smart Ads is agnostic as to the identity of
the ad and does not know how often a particular ad is clicked on, let alone how often it’s clicked
on in response to a given query. (Id., 1110:7-10.)
Plaintiff also misrepresents Dr. Ungar’s testimony at trial. Dr. Ungar never testified that
mindpools were necessary for infringement.8 (Opp., 17-19; Trial Tr., 1445:7-10 (testimony from
Dr. Ungar confirming his opinion that mindpools are not required for infringement).) Instead, he
testified, consistent with the Court’s claim construction, that collaborative feedback data must be
collaborative, and thus must be data from system users with similar interests or needs. (Trial Tr.,
1240:20-1241:8.) As a matter of common sense, in order to identify feedback data from users
with similar interests or needs, it is necessary to group those users so that the feedback from such
uses can be separated from users generally. Indeed, Plaintiff has never explained how this could
be done without grouping users in some manner.
2. Dr. Frieder’s misleading testimony regarding historical CTR
warrants a new trial.
As Defendants detailed in their motion, Plaintiff purposefully elicited inconsistent and
misleading testimony from Dr. Frieder during trial that SmartAds uses historical CTR. (Br., 1415.) Plaintiff argues Dr. Frieder never stated that collaborative data is click-through rate. (Opp.,
19.) Dr. Frieder’s testimony illustrates otherwise. For example, Dr. Frieder relied on PX-338, a
Google marketing document, to state “[a]s you see, it is in green, and from their own documents,
it says, ‘Your keyword’s past click-through rate,’ namely, ‘how often that keyword led to clicks
of your ad.’ That is a function, it’s a part of what they are using to calculate the quality score.
There is no doubt that that is collaborative.” (Trial Tr., 489:2-7 (emph. added); see also id.,
Dr. Ungar explicitly stated that he was only using the mindpools as an example from
the specification. (Trial Tr., 1232:3-13; 1445:2-20; 1446:18-22.) Dr. Frieder repeatedly used
figures from the specification as examples in his analysis. (See id., 445:5-450:4, 450:22-456:18.)
490:3-5.) While Dr. Frieder later testified on cross-examination that CTR was not used by
SmartAds and that he was not relying on CTR as the collaborative data required by the claims
(Id., 680:9-12), Plaintiff unquestionably elicited testimony on direct to the contrary (knowing full
well that at his deposition he testified in the same manner that he did on cross). Plaintiff then
improperly relied on such testimony during its closing arguments, by repeatedly citing to
historical CTR in its attempt to demonstrate that the Accused Systems meet the collaborative
data limitations of the asserted claims. (PDX-418, PDX-419, PDX-423, PDX-424, PDX-425,
PDX-426, PDX-427, PDX-428, PDX-429, PDX-430, PDX-431, PDX-432.) At a minimum, a
new trial should be granted. 800 Adept, Inc. v. Murex Sec., Ltd., 539 F.3d 1354, 1369 (Fed. Cir.
2008); Cline v. Wal-Mart Stores, Inc., 144 F.3d 294, 301 (4th Cir. 1998).
THERE WAS NO LEGALLY SUFFICIENT BASIS TO FIND THAT THE
ACCUSED SYSTEMS ARE A SEARCH ENGINE OR A SEARCH SYSTEM
Plaintiff Successfully Relied On The Preamble In Order To Prove
Infringement And Rebut Defendants’ Invalidity Arguments.
The preambles of asserted claims 10 and 25 of the ‘420 patent and claim 1 of the ‘664
patent recite a “search engine system” and “search system,” respectively. Plaintiff does not deny
that Dr. Frieder relied on these preambles to illustrate that the Accused Systems purportedly
infringe each limitation in the asserted claims. Instead, Plaintiff argues that Dr. Carbonell did
not use the preambles as limitations. (Opp., 5-6.) Looking at Dr. Carbonell’s full testimony, it is
evident that he did rely on the preambles to support his opinion that the patents are valid. In
particular, Dr. Carbonell testified that what distinguished the claimed inventions from the prior
art was the tight integration of “collaborative analysis” and “content-based analysis with respect
to a query”. (Trial Tr., 1835:24-1836:19 (emph. added).) According to Dr. Carbonell, it was this
use of the search engine/search system that made the claimed inventions valid: “In other words,
to use the immediate information need, not just a long-term standing need, of the users, and then
filter also with respect to the query, filter with respect to the immediate need, not just simply
filter with respect to what they generally liked.” (Id.)
Defendants Were Not Allowed to Introduce Evidence to Rebut Plaintiff’s
Dr. Frieder was allowed to “check the box” to show that the Accused Systems met the
“search engine” element in the preamble of the accused claims. Defendants were not allowed to
“uncheck” the same box on the grounds that the preamble was not a limitation. This disparate
treatment confused the jury and prejudiced Defendants. Because Defendants were not allowed
equivalent treatment of their non-infringement case, Defendants are entitled to a new trial.
Meyer Intellectual Props. Ltd. v. Bodum, Inc., 690 F.3d 1354, 1377 (Fed. Cir. 2012).
The Preambles Of The Asserted Claims Are Limiting.
Defendants in their opening brief explained why the preambles in the asserted claims in
this case are limiting to the scope of the claims, citing to the Federal Circuit’s standard in
support. (Br., 18-19 (citing Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801,
808-09 (Fed. Cir. 2002)).) As Defendants demonstrated, for each asserted claim the preamble
gives life, meaning, and vitality to the claim in that the preamble makes clear that the claimed
systems and methods must actually search for resources in order to locate information, instead of
merely retrieving information from a known location. (Id.) Plaintiff just ignores this.
The Accused Systems Do Not Meet The Preambles’ “Search Engine” Or
“Search System” Limitations.
Plaintiff argues that the Accused Systems have a “search engine environment” and a
“search process.” (Opp., 4.) In so doing, Plaintiff ignores its own admissions during trial.
Plaintiff repeatedly stated that Google Search was not accused in this case. (See, e.g., Trial Tr.,
116:7-12, 117:2-5, 133:3-5.) As the evidence demonstrated at trial, there is no separate search
engine for the Accused Systems—instead, queries are run in Google Search. (Id., 1091:2211
1092:13.) Having admitted that Google Search is not accused, Plaintiff cannot now point to
Google Search in order to meet the preambles’ search engine or search system limitations.
According to Plaintiff, AdWords is a search system because the “AdWords system ‘starts
with end users when they enter a search query.’” (Id., 4 (citations omitted).) Not only is this
argument illogical, it is fundamentally flawed because Plaintiff never previously argued that the
use of a query made AdWords a search engine or search system. Dr. Frieder did not make this
argument either in his expert reports or at trial, nor did Plaintiff present any argument on this
point at trial. Instead, Plaintiff repeatedly and specifically characterized the Accused Systems as
advertising systems, in contrast to Google’s search system. (See, e.g., Trial Tr., 107:21-24,
133:3-5.) Having failed to present any such evidence at trial, Plaintiff cannot rely on it for the
first time in post-trial motions to avoid its failure of proof at trial.
THE ACCUSED SYSTEMS DO NOT SCAN OR SEARCH FOR ADS
Scanning/searching element (All claims): Plaintiff does not dispute that advertisers
submit their ads to Google for inclusion in a database or that Google organizes and stores these
submitted ads based on their associated keywords. (D.N. 755-1, 13, ¶ 6.) Thus, it is undisputed
that Google knows where each ad is stored and AdWords does not have to go out and look for an
ad in response to a query. As such, AdWords does not have to “look for or examin[e] items in
a network” or “search for information relevant to a query” as required by the asserted claims.
In its Opposition, Plaintiff continues to rely on “targeting” as its basis for claiming that
the Accused Systems scan or search for ads. But “targeting” is just a high-level term, not a
function in the Accused Systems. Plaintiff’s only retort is that the document it relies on is
circulated to internal software engineers. (Opp., 8.) Regardless of who the document is
circulated to, Plaintiff still has not identified any instrumentality or specific functionality that
performs this “targeting.” See Fresenius, 582 F.3d at 1300.
Plaintiff next argues that the jury disregarded Dr. Ungar’s “hyper-technical”
interpretation. But Dr. Ungar was merely adhering to the Court’s construction which requires
“looking for” and not “looking up.”9 See Cordis Corp. v. Boston Sci. Corp., 658 F.3d 1347,
1357-1358 (Fed. Cir. 2011) (affirming judgment as a matter of law of no literal infringement
when patentee’s expert testimony of infringement was based on an “incorrect understanding of
the claim construction”). As it is undisputed that the ads are organized and stored by AdWords,
it is also undisputed that AdWords would need to look for the ads it wanted to retrieve.10
Demand search (Claims 10 and 25 of the ‘420 Patent): Plaintiff has still failed to
identify any evidence in the record that the Accused Systems meet the “demand search”
limitation. Plaintiff cites Dr. Frieder’s testimony, but this testimony addresses the scanning and
“scanning a network” limitations. (See Trial Tr., 483:14-494:4 (“Q. Do you have the definition
underneath of the claim on PDX-089 on the screen? A. Yes. . . What it simply means is,
“Scanning a network means: Looking for or examining items in a network. . . so by finding,
you’re looking for. To find you need to look for.”).) I/P Engine points to nothing in the record
as evidence that the “demand search” limitation is met.
Network (Claims 10 and 25 of the ‘420 Patent): Plaintiff has also still failed to explain
how the Accused Systems scan a network. Plaintiff argues that the candidate ads are stored on a
set of connected computers, i.e., “AdShards (also known as the ads database).” (Opp., 7.)
Plaintiff, however, has not explained or provided any evidence that a database is the same as a
Far from being “hyper-technical,” the different prepositions dramatically change the
meaning of the phrase. Consider the difference between “looking for a friend” and “looking up a
friend.” Similarly, AdWords need not look for ads, as it already knows where they are. It need
only look up information relating to the ads.
Plaintiff’s citation to the landing page relevance (Opp., 9 n.4) is also not evidence of
infringement as the claims require scanning/searching for “informons” and filtering the
“informon[s].” It is undisputed that landing pages are not filtered, and, as such, Plaintiff points
to no evidence of any such filtering. Any searching or scanning for landing pages is irrelevant.
network, let alone that “scanning a database” is the same as “scanning a network.”11
Accordingly, Plaintiff has still failed to show that the accused systems scan a network.
THERE WAS NO LEGALLY SUFFICIENT BASIS TO FIND THAT THE
ACCUSED SYSTEMS FILTER FOR RELEVANCE TO THE QUERY
Dr. Frieder admitted that the Accused Systems disable ads based on the Long Term
Value (LTV) score, not the pCTR. (Trial Tr., 697:23-698:7.) Plaintiff does not dispute this.
Instead, Plaintiff argues that AdMixer disabling and promotion disabling both involve filtering
for relevance to the query because “[t]he fact that additional factors are included in filtering for
these two disabling steps does not eliminate or excuse Defendants’ liability for infringement.”
(Opp., 25 (citations omitted).)
Plaintiff’s argument misses the point. AdWords does not filter by pCTR—and therefore
does not infringe—because a higher pCTR does not necessarily lead to an advertisement being
eligible for the auction. Instead, because the use of the LTV score creates a “reserve price,”
advertisers’ bids must be high enough to meet that reserve price in order to be eligible for the
auction; advertisers whose bids are not high enough are disqualified from the auction. (Trial Tr.,
697:23-698:7.) Thus, the alleged filtering is based on whether the bid is sufficiently high to
overcome the reserve price, not based on the value of the pCTR. Even if pCTR were a measure
of relevance to the query, and it is not, the fact that ads with low pCTRs might qualify for the
auction and ads with high pCTRs might be disqualified from the auction is proof positive that
AdWords does not filter based on pCTR. (Trial Tr., 1103:25-1104:13, 1460:19-1461:12.)
Nor has I/P Engine explained how a “whole diverse machine” or how “distributed
computing machinery” is a network. Plaintiff also points to discussion of how the SmartAds
database is on the network. Plaintiff, however, has failed to show that the Accused Systems scan
that “network” to find informons. Rather, even under Plaintiff’s infringement theory, the only
thing “scanned” is the ads database not the network the ads database resides upon.
Unlike the cases cited by Plaintiff, this is not a situation where a product infringes even though it
includes additional features; here, the system simply does not infringe.
Plaintiff also argues that Defendants do not dispute that QBB disabling meets this
limitation. (Opp., 25.) This is plainly false. As noted in Defendants’ opening brief, Google
engineer Bartholomew Furrow explained that QBB disabling is performed independent of the
query and, in fact, before the user inputs a query. (Trial Tr., 1097:8-11.) Because QBB
disabling happens before the query, it cannot be related to the query. Plaintiff makes no effort to
dispute this point, and can cite to no evidence to the contrary.
PLAINTIFF RELIED ON IRRELEVANT MARKETING DOCUMENTS
Plaintiff’s infringement case was fundamentally flawed because it relied primarily on
marketing documents, encouraging the jury to ignore the most detailed evidence of how the
Accused Systems work, the source code. While Plaintiff argues that it relied on additional
evidence to prove infringement, Plaintiff does not even try to rebut that Dr. Frieder’s only
limitation-by-limitation infringement analysis relied on marketing documents. (Trial Tr.,
486:17-490:18; PDX 57-59, 91-93, 98, 119, 126-128, 133-35, 139-41.) Indeed, throughout its
opposition brief Plaintiff continues to rely on marketing and other high-level documents to
support its argument that the Accused Systems meet the claim limitations. (Opp., 4, 6-8, 10, 18.)
But Plaintiff cannot rely on marketing documents to override how those systems actually work.
Whirlpool Corp. v. LG Elecs., Inc., 2006 WL 2035215, at *8 (W.D. Mich. July 18, 2006).12
Defendants cited multiple cases illustrating that reliance on marketing documents is
insufficient to show infringement as a matter of law. (Br., 24.) Plaintiff’s attempts to distinguish
these cases fail. (Opp., 27 n.14.) Plaintiff first argues that the marketing documents in
PharmaStem Therapeutics, Inc. v. ViaCell, Inc., 491 F.3d 1342, 1351-52 (Fed. Cir 2007) were
less reliable than the marketing documents here because they “did not equate to the documents
here where Google describes with specificity its practicing of the patented features.” (Id.)
However, Plaintiff and its infringement expert Dr. Frieder have admitted that Google’s
marketing documents discuss things that are not actually used in SmartAds, such as a keyword’s
Moreover, as detailed in Defendants’ brief, Plaintiff itself admitted during trial that the
marketing documents it relied upon were not relevant because they pertained to the non-accused
Quality Score 1 through 10, rather than an accused Quality Score. (Trial Tr., 645:15-19 (PX
338); id., 647:3-5 (PX 51); 647:15-649:1 (PX 357); 650:1-651:9 (PX 112); 667:6-17 (Hal Varian
video); 2064:1-19 (Plaintiff’s counsel admitting during closing argument that these documents
referred to the non-accused Quality Score).) But Plaintiff now argues that these documents
relate both to the non-accused Quality Score and the accused Quality Score. (Opp., 26-27.)
Even if Plaintiff were correct, this only further illustrates the problem with relying on these
documents as evidence of infringement, especially when detailed evidence of how the systems
actually work is available in the form of source code.13
historical CTR. (Trial Tr., 673:12-14; id., 677:11-18.) Given that these marketing documents
discuss functionalities that are not actually practiced by the Accused Systems, they suffer from
the same significant “gaps in proof” as in Pharmastem, and therefore do not provide a sufficient
basis for a finding of infringement. Plaintiff next argues that Whirlpool Corp., 2006 WL
2035215, at *8, is distinguishable because “the advertising literature in that case were in direct
contradiction to the facts regarding the actual operation of the accused product.” (Br., 27 n.14.)
Again, Plaintiff has admitted that Google’s marketing documents directly contradict the facts
regarding the actual operation of the Accused Systems. Just as in Whirlpool Corp., Plaintiff
cannot rely upon Google’s marketing documents to prove infringement. Finally, Plaintiff argues
that Scantibodies Lab., Inc. v. Immutopics, Inc., 374 F. App’x 968, 971 (Fed. Cir. 2010) does not
apply because “it involves claim construction arguments where a court chose to view the claims
based on their plain meaning rather than the language in a marketing document.” (Br., 27 n.14.)
Again, Plaintiff’s argument misses the point. As the Court in Scantibodies properly recognized,
“[t]he use of language in marketing materials often means something quite different from the
language used in a patent.” Id. Language used in Google’s marketing documents is insufficient
to prove infringement, and Plaintiff’s primary reliance on such documents is improper, especially
in the face of contradictory evidence of how the systems actually work.
As both Google and Dr. Frieder himself testified, it is the source code that explains
how the Accused Systems actually work. (Trial Tr., 593:2-3.) The testimony of Mr. Alferness
that these documents are “a proxy or a – an abstraction of what’s actually happening under the
covers,” cited by Plaintiff, is of no help to Plaintiff. (Opp., 26 (citing D.N. 755-1, 2, ¶ 6).) An
“abstraction” is not evidence of infringement.
PLAINTIFF FAILED TO PROVE INDIRECT INFRINGEMENT
Active Inducement: To establish active inducement, I/P Engine needed to show that
Google purposefully caused others to directly infringe the asserted claims in the patents-in-suit.
Specifically, it needed to prove that Google (i) had actual knowledge of the patents-in-suit and
(ii) specifically intended for others to perform acts that directly infringe one or more of the
asserted claims. Global-Tech Appliances, Inc. v. SEB S.A., 131 S. Ct. 2060, 2068 (2011). The
Supreme Court, in Global-Tech, rejected the earlier Federal Circuit standard for intent, a
standard that the Court described as akin to recklessness. Id. at 2070-2071. Instead, the
Supreme Court held that specific intent requires actual knowledge that the induced acts
constitute infringement. Id. Plaintiff’s arguments and “evidence” fail to meet this standard.
Plaintiff does not even try to present evidence that would meet the standard set by Global-Tech.
Instead, Plaintiff argues that there is evidence that Google had actual knowledge of the
patents-in-suit, once again referring to the citation to the ‘420 Patent during prosecution of
Google’s own patent application. (Opp., 29.) This is insufficient as a matter of law to show
actual knowledge of the patents-in-suit by Google. Veritas Operating Corp. v. Microsoft Corp.,
562 F. Supp. 2d 1141, 1285 (W.D. Wash. 2008) (“[H]aving ‘knowledge’ of a single patent only
because it was cited during prosecution of two patents among thousands (and then only through
imputing that knowledge from [the defendant’s] attorneys) does not give [the defendant]
sufficient ‘knowledge’ to formulate ‘intent’ required for inducement.”).
Second, Plaintiff argues that there is “circumstantial evidence” that Google induced
others to use the Accused Systems, and that “Google has induced others to directly infringe the
‘420 and ‘664 patents by making for and selling to (via revenue sharing agreements) third party
publishers the AdWords system with material that provide instructions and information for using
the AdWords system.” (Opp., 28.) But instructing users how to use a system, even in an
allegedly infringing manner, does not give rise to inducement liability unless the defendant has
“knowledge that the induced acts constitute patent infringement.” Global-Tech, 131 S. Ct. at
2070-71 (emph. added). Moreover, Plaintiff has never come forward with any evidence that
Defendants know or believe there is a high risk that they induce infringement of one or more of
any asserted valid claim in any manner. There is no evidence that Defendants had pre-suit
knowledge of the patents-in-suit, Plaintiff admitted that it did not contact Google prior to trial
(Trial Tr., 205:1-4), and nothing that happened since demonstrates the necessary intent for any
Defendant. Rather, Defendants’ substantial non-infringement and invalidity defenses show that
they reasonably and consistently have believed they do not induce infringement. (D.N. 821,
832.) See Mikkelsen Graphic Engineering Inc. v. Zund America, Inc., No. 07–C–0391, 2011 WL
6122377, at *7-8 (E.D. Wis. Dec. 8, 2011).
Contributory Infringement: A party is liable for contributory infringement only if it
“offers to sell or sells within the United States or imports into the United States a component of a
patented machine, manufacture, combination or composition, or a material or apparatus for use
in practicing a patented process, constituting a material part of the invention,” while knowing
that it is “especially made or especially adapted for use in an infringement of such patent, and not
a staple article or commodity of commerce suitable for substantial noninfringing use.” 35 U.S.C.
§ 271(c). To succeed on a claim of contributory infringement, the patentee must prove “1) that
there is direct infringement, 2) that the accused infringer had knowledge of the patent, 3) that the
component has no substantial noninfringing uses, and 4) that the component is a material part of
the invention.” Fujitsu Ltd. v. Netgear Inc., 620 F.3d 1321, 1326 (Fed. Cir. 2010). Thus, it is
not enough to prove an act of direct infringement by another, I/P Engine must also prove that the
Defendants “‘knew that the combination for which its components were especially made was
both patented and infringing’ and that [Defendants’] components have no ‘substantial
noninfringing use[s].’” Lucent Techs., Inc. v. Gateway, Inc., 580 F.3d 1301, 1320 (Fed. Cir.
2009) (quotation omitted). As with inducement, Plaintiff ignores this standard—just as it chose
not to present evidence to meet it at trial.
As outlined above, Plaintiff has failed to prove that Defendants directly infringe the
patents-in-suit or that Defendants had the required knowledge of the patents-in-suit. Therefore,
Plaintiff cannot show that any Defendant “knew that the combination for which its components
were especially made was both patented and infringing.” Lucent Techs., 580 F.3d at 1320.
Nor does Plaintiff point to “a component of a patented machine, manufacture,
combination or composition, or a material or apparatus” that it alleges is “especially made or
especially adapted for use in an infringement of such patent, and not a staple article or
commodity of commerce suitable for substantial noninfringing use.” 35 U.S.C. § 271(c).
Instead, Plaintiff points to the entire Accused Systems, which are not components used in
another system. And while Plaintiff argues that “the accused features have no substantial noninfringing uses,” it identifies no evidence in support of this argument. (Opp., 29.) Plaintiff’s
bald statement is insufficient to support a finding of infringement. Finally, because Plaintiff does
not point to an “allegedly infringing component,” it cannot and does not assert that the allegedly
infringing component is a material part of the invention.14
Plaintiff argues “the inclusion of an indirect infringement instruction makes no
difference in the calculation of damages, and at worst was harmless error.” (Opp., 29 n.15.) But
Plaintiff’s entire damages theory is based on a hypothetical negotiation in 2004, based on a 2004
date of first infringement—seven years prior to the filing of the Complaint, which affects the
calculation of damages, and is not harmless error.
PLAINTIFF FAILED TO PROVE INFRINGEMENT UNDER THE DOCTRINE
I/P Engine presented no evidence at trial in support of its allegation that Defendants are
liable for infringement under the doctrine of equivalents. Plaintiff provided no evidence to
demonstrate that the Accused Systems “performs substantially the same function in substantially
the same way to obtain the same result” as the invention claimed in the patents-in-suit. WarnerJenkinson Co., Inc. v. Hilton Davis Chem. Co., 520 U.S. 17, 38 (1997) (citation omitted). Nor
did Plaintiff provide any evidence of insubstantial differences between the Accused Systems and
the inventions claimed in the patents-in-suit. Id. at 40. Plaintiff’s argument to the contrary is
both conclusory and without merit—simply stating that it presented evidence “where necessary
of a substantial equivalent” without citing to any trial testimony in support. (Opp., 30.)
Just as in Lear Siegler, Inc. v. Sealy Mattress Co., 873 F.2d 1422, 1426 (Fed. Cir. 1989),
because Plaintiff did not provide evidence or argument “explicitly setting forth equivalence of
result, function, and means, the trial court should not have instructed the jury on the doctrine.”
Moreover, because a separate interrogatory was not provided in the verdict form, it is impossible
to know whether the jury found infringement under the doctrine of equivalents. Thus, the
inclusion of a jury instruction on the doctrine of equivalents was not “harmless error” as Plaintiff
alleges. (Opp., 30.) Instead, because no evidence or argument was presented about the doctrine
of equivalents, Defendants are entitled to judgment as a matter of law that they did not infringe
under the doctrine of equivalents. And because the jury was allowed to consider that doctrine in
determining infringement but the Court did not submit a special interrogatory about it, the Court
should grant a new trial to ensure the jury did not find infringement based on a wholly
unsupportable theory. Warner-Jenkinson Co., 520 U.S. at 39 n.8.
