Case No. 15-cv-00966-BLF
12
13
Plaintiff Richard Williamson (“Williamson”), Trustee of At Home Bondholders’
14
Liquidating Trust, brings this patent infringement lawsuit against Defendant Google Inc.
15
(“Google”). The complaint alleges Google’s AdSense and other products infringe two patents:
16
U.S. Patent No. 6,014,698 (the “’698 patent”), directed at using first banner request that cannot be
17
blocked from reaching a server for accurately counting displays of banners on network terminals,
18
and U.S. Patent No. 6,286,045 (the “’045 patent”), directed at information storage and delivery
19
over a computer network using centralized intelligence to monitor and control the information
20
being delivered. Compl., ECF 1; Exs. A and B to Compl. The Court held a tutorial on June 8,
21
2017, and a Markman hearing on June 16, 2017, for the purpose construing eight disputed terms
22
that are in the asserted claims of the ’045 and the ’698 patents.
23
I.
BACKGROUND ON THE ’045 AND THE ’698 PATENTS
The ’698 patent is a continuation-in-part of the ’045 patent and Williamson admits that the
24
25
specifications are almost identical. Revised Opening Claim Constr. Br. (“Opening Br.”) 8, ECF
26
139. As such, the discussion of the ’045 patent applies equally to the ’698 patent unless otherwise
27
noted.
28
The ’045 patent relates to serving information over a network, such as an advertisement, to
1
a client device, such as a personal computer, and accurately counting the number of times an
2
advertisement is displayed. ’045 patent at 3:34-41, Ex. B to Compl., ECF 1-2. According to the
3
’045 patent, the prior art method did not allow for accurate counting of the display due to
4
“caching.” Id. at 6:36-7:7; 12:56-66. “Caching” pertains to the process of storing previously
5
requested information on a user’s computer or a proxy server and providing the stored copy in
6
response to a request, instead of obtaining the requested information from the server. Id. at 6:36-
7
7:7; 12:56-13:2. While caching increases the speed at which information is displayed and reduces
8
the traffic on the network, it prevents accurate counting of the display and interferes with the
9
ability to select the precise advertisement to be displayed. Id. at 13:46-14:32.
The ’045 patent attempts to solve this problem by requiring a mandatory initial request to
10
United States District Court
Northern District of California
11
be transmitted each time banner information is requested. Id. at 14:33-40; 14: 57-15:3;
12
19:63:20:14. After the initial request is sent, there would be an opportunity to select the specific
13
content to be displayed, if desired, prior to responding to that initial request. Id. at 15:8-22. That
14
response can then either provide the location information of the content to be displayed or other
15
identifying information of the content. Id. at 15:34-44. If the content is already cached, the
16
content will be displayed. Id. at 15:48-56. If it is not, a second request will be transmitted to
17
obtain the content from a server. Id. at 15:56-60. According to the ’045 patent, the invention thus
18
allows for accurate counting of the content display due to the mandatory initial request while at the
19
same time imposing very little burden on the network traffic. Id. at 19:63-20:36.

LEGAL STANDARD
17
A.
18
Claim construction is a matter of law. Markman v. Westview Instruments, Inc., 517 U.S.
19
370, 387 (1996). “It is a ‘bedrock principle’ of patent law that ‘the claims of a patent define the
20
invention to which the patentee is entitled the right to exclude,” Phillips v. AWH Corp., 415 F.3d
21
1303, 1312 (Fed. Cir. 2005) (en banc) (internal citation omitted), and, as such, “[t]he appropriate
22
starting point . . . is always with the language of the asserted claim itself,” Comark Commc’ns, Inc.
23
v. Harris Corp., 156 F.3d 1182, 1186 (Fed. Cir. 1998).
24
General Principles
Claim terms “are generally given their ordinary and customary meaning,” defined as “the
25
meaning . . . the term would have to a person of ordinary skill in the art in question . . . as of the
26
effective filing date of the patent application.” Phillips, 415 F.3d at 1313 (internal citation
27
omitted). The court reads claims in light of the specification, which is “the single best guide to the
28
meaning of a disputed term.” Id. at 1315; see also Lighting Ballast Control LLC v. Philips Elecs.
3
1
N. Am. Corp., 744 F.3d 1272, 1284-85 (Fed. Cir. 2014) (en banc). Furthermore, “the
2
interpretation to be given a term can only be determined and confirmed with a full understanding
3
of what the inventors actually invented and intended to envelop with the claim.” Phillips, 415
4
F.3d at 1316 (quoting Renishaw PLC v. Marposs Societa’ per Azioni, 158 F.3d 1243, 1250 (Fed.
5
Cir. 1998)). The words of the claims must therefore be understood as the inventor used them, as
6
such understanding is revealed by the patent and prosecution history. Id. The claim language,
7
written description, and patent prosecution history thus form the intrinsic record that is most
8
significant when determining the proper meaning of a disputed claim limitation. Phillips, 415
9
F.3d at 1315-17; see also Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir.
10
1996).
Evidence external to the patent is less significant than the intrinsic record, but the court
United States District Court
Northern District of California
11
12
may also consider such extrinsic evidence as expert and inventor testimony, dictionaries, and
13
learned treatises “if the court deems it helpful in determining ‘the true meaning of language used
14
in the patent claims.’” Philips, 415 F.3d at 1318 (quoting Markman, 52 F.3d at 980). However,
15
extrinsic evidence may not be used to contradict or change the meaning of claims “in derogation
16
of the ‘indisputable public records consisting of the claims, the specification and the prosecution
17
history,’ thereby undermining the public notice function of patents.” Id. at 1319 (quoting
18
Southwall Techs., Inc. v. Cardinal IG Co., 54 F.3d 1570, 1578 (Fed. Cir. 1995)).
19
20
B.
Indefiniteness
“The Patent Act requires that a patent specification conclude with one or more claims
21
particularly pointing out and distinctly claiming the subject matter which the applicant regards as
22
the invention.” Nautilus v. Biosig Instruments, 134 S. Ct. 2120, 2124 (2014). “A patent is invalid
23
for indefiniteness if its claims, read in light of the specification delineating the patent, and the
24
prosecution history, fail to inform, with reasonable certainty, those skilled in the art about the
25
scope of the invention.” Id. While the scope of the claims must be clear enough to “apprise the
26
public of what is still open to them,” Markman, 517 U.S. at 373, “the definiteness requirement
27
must take into account the inherent limitations of language. Some modicum of uncertainty . . . is
28
the price of ensuring the appropriate incentives for innovation.” Nautilus, 134 S. Ct. at 2128
4
1
(internal citations omitted). Thus, “the certainty which the law requires in patents is not greater
2
than is reasonable, having regard to their subject-matter.” Id. at 2129 (quoting Minerals
3
Separation v. Hyde, 242 U.S. 261, 270 (1916)).

CONSTRUCTION OF DISPUTED TERMS AND PHRASES
A.
“banner”
Williamson’s Proposal
“information displayed in
conjunction with a web page”
Google’s Proposal
“information displayed in
conjunction with a web page
wherein the information is not
part of the same file as the
web page”
Court’s Construction
“information displayed in
conjunction with a web page”
The disputed term “banner” appears in asserted independent claims 20, 34, 64, 72, 75 of
the ’045 patent and independent claims 17, 39, 44 of the ’698 patent. Claim 20 of the ’045 patent
is set forth below as an example of how the term is used:
20. A method for distributing a banner over a computer network to a device when the
banner is referenced or linked to in a document served to the device, wherein the
banner is stored in one or more servers, comprising:
receiving a first banner request signal from a device at a first server requesting that
a banner be served to the device, wherein said first banner request signal includes
information intended to prevent said first banner request signal from being blocked
from reaching said first server by the device despite previous caching of said
specified banner in the device;
sending a banner location signal from said first server to the device, wherein said
banner location signal includes location information for a specified banner stored
on a second server; and
receiving a second banner request signal from the device at said second server
requesting that the second server serve said specified banner to the device.

28
’045 patent at 28:38-55 (emphasis added).
While the parties agree that “banner” refers to information displayed in conjunction with a
web page, they disagree whether it must be separate from the web page file. Williamson argues
that requiring it to be separate from the web page file is contrary to the specification’s express
disclosures. Opening Br. 9. Google claims that its proposed construction actually comports with
the patentee’s chosen lexicography in defining “banner,” and is also consistent with Williamson’s
own representation during the inter partes review (“IPR”) proceedings. Resp. Br. 2-3, ECF 137.
5
1
Google concludes that “banner” thus should be defined based on the express definition in the
2
specification.
3
The Court agrees with Williamson and finds that the evidence does not support Google’s
8
proposed construction. The patents expressly define “banner” as follows:
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.
9
’045 patent at 2:27-35 (italics added). Based on this definition, “banner” is defined to include an
4
5
6
7
embodiment “wherein the information is not part of the same file as the web page,” without
11
United States District Court
Northern District of California
10
excluding a situation where the information is part of the same file. The broader construction
12
advocated by Williamson is further supported by the disclosure describing the invention in context
13
of one of the figures:
14
15
16
The banner information may be served with the web page or, more
commonly, the banner information may reside in separate files which will
need to be requested by the user’s terminal 36 before the banner
information can be displayed on the user’s terminal 36 along with the
requested web page.
17
Id. at 10:22-27. This disclosure is consistent with the construction that “banner” could encompass
18
information “served with the web page,” as well as those that “reside in separate files.” Oatey Co.
19
v. IPS Corp., 514 F.3d 1271, 1276 (Fed. Cir. 2008) (“We normally do not interpret claim terms in
20
a way that excludes embodiments disclosed in the specification.”).
21
Citing Allergan, Inc. v. Apotex Inc. and Sinorgchem Co., Shandong v. Int’l Trade
22
Comm’n., Google argues that the use of quotation marks and the use of “includes” signal a
23
patentee’s choice to act as its own lexicographer, and that a proper construction should exclude the
24
embodiment contrary to that lexicography. Resp. Br. 3 (citing 754 F.3d 952, 957 (Fed. Cir. 2014);
25
511 F.3d 1132, 1138 (Fed. Cir. 2007)). However, those cases are inapposite and do not compel a
26
different conclusion. The court in Sinorgchem held that embodiments are excluded from the
27
definition of a term if “those embodiments are inconsistent with unambiguous language in the
28
patent’s specification or prosecution history.” 511 F.3d at 1138. The Sinorgchem court, however,
6
1
did not consider the use of the term “includes,” in a manner similar to how “banner” is defined
2
here. Unlike this case, the patent in Sinorgchem had “express definitional language” that excluded
3
certain embodiments. Id. at 1136, 1138 (noting that the definition was provided in the patent as:
4
“[a] ‘controlled amount’ of protic material is an amount up to that which inhibits the reaction of
5
aniline with nitrobenzene, e.g., up to about 4% H2O based on the volume of the reaction mixture
6
when aniline is utilized as the solvent”). As such, Sinorgchem is not analogous to the situation
7
here. Allergan is similarly inapplicable and also fails to support Google’s arguments. The
8
Allergan court noted that the use of “includes” means that the patentee intended to define a term to
9
include a list of items that is to follow. 754 F.3d at 957. But the court did not find that the
definition of the phrase should be circumscribed only to that list. Id. at 958. Rather, the holding
11
United States District Court
Northern District of California
10
hinged on the interpretation of the conjunctive “and” in the definition, which is not at issue here.
12
Id. at 957. Notably, the Allergan court resorted to “numerous examples in the patent” to arrive at
13
its construction of the term. Id. at 958. In the same way, considering the embodiments set forth in
14
the ’045 patent specification leads this Court to construe the term to encompass an embodiment
15
where the “banner information may be served with the web page.” As to Williamson’s
16
representation during IPR with regard to this term, the construction advocated by Williamson
17
during the IPR proceeding did not exclude this embodiment, either.
Accordingly, the Court adopts Williamson’s construction because the definition introduced
18
19
by the use of “includes” does not exclude an embodiment where the “banner information may be
20
served with the web page.”
21
B.
“content specific request”
22
23
24
Williamson’s Proposal
“A content request that does
specify particular content
and/or location thereof”
Google’s Proposal
“a request that specifies the
location of particular content”
Court’s Construction
“A content request that does
specify particular content
and/or location thereof”
25
26
27
28
The disputed phrase “content specific request” appears in asserted dependent claim 5 of the
’045 patent, and dependent claims 7 and 20 of the ’698 patent. Claim 5 of the ’045 patent
ultimately depends on claim 1 and is set forth below as an example of how the phrase is used:
7
5. The method of claim 4, wherein said second request signal is a
content specific request signal.
1
2
’045 patent at 27:61-62 (emphasis added).
Williamson first contends that a construction beginning with “a content request,” as
4
opposed to “a request,” more accurately reflects the character of the request, namely, a request for
5
content. Opening Br. 10. Williasom also avers that a construction beginning with “a content
6
request” would be consistent with the agreed-upon construction for “content general request.” Id.
7
It next argues that Google’s construction is overly limiting by requiring that the request always
8
specifies the location of a particular content. Id. at 11; Reply 3, ECF 140. Responding to
9
Williamson’s first point, Google notes the difference between “a content request” and “a request”
10
to be immaterial and does not believe that to be the crux of the dispute. Resp. Br. 4 n.2. Rather,
11
United States District Court
Northern District of California
3
the issue is whether “a request” always specifies the location of a particular content. Google
12
argues that the specification supports the requirement that a content-specific request always
13
contains the location. Id. at 5. Google also claims that Williamson’s construction renders the term
14
indefinite because it fails to distinguish specifying particular content from specifying location
15
thereof. Id.
16
The Court does not agree with Google that the claim scope should be narrowed based on a
17
limitation from the specification that is not incorporated into the claim itself, and thus adopts
18
Williamson’s construction. Although understanding of this phrase may be aided by the written
19
description, which explains that a content specific request can contain URL or IP addresses, “it is
20
important not to import into a claim limitations that are not a part of the claim.” Resonate Inc. v.
21
Alteon Websystems, Inc., 338 F.3d 1360, 1364 (Fed. Cir. 2003). The disputed phrase – “content
22
specific request” – specifies nothing regarding what the request must contain and contains no
23
language regarding whether it must contain a URL address, IP address, or other types of location
24
information. Based on the plain language of the disputed phrase, if a piece of information other
25
than location can be used to specify a particular content, the phrase would encompass that.
26
The parties rely on various sections of the specification in support of their respective
27
arguments. Although those sections of the specification often refer to URL or IP addresses as a
28
means to specify a particular content, there is no need to narrow the term to require the “location”
8
1
limitation. The patentee is not required to set forth in the claim language the specific detail of how
2
the request specifies the particular content. Nor does the Court need to narrow the scope of the
3
claim based on examples in the specification that have been omitted from a claim. See K-2 Corp.
4
v. Salomon S.A., 191 F.3d 1356, 1364 (Fed. Cir. 1999) (“Courts do not rewrite claims; instead, we
5
give effect to the terms chosen by the patentee.”); Autogiro Co. of Am. v. United States, 384 F.2d
6
391, 396 (Ct. Cl. 1967) (“Courts can neither broaden nor narrow the claims to give the patentee
7
something different than what he has set forth.”).
The Court also does not find persuasive Google’s argument that Williamson’s construction
8
9
is indefinite. Google contends that the patent contains no disclosures concerning the selection of
particular content other than referencing a server or an address. Resp. Br. 5. As such, Google
11
United States District Court
Northern District of California
10
concludes it is thus unclear how “specifying particular content” could be different from
12
“specifying location.” However, not having adequate disclosure in support of a claim does not
13
render a claim invalid for indefiniteness. Rather, a claim is indefinite when it “fail[s] to inform,
14
with reasonable certainty, those skilled in the art about the scope of the invention.” See Nautilus,
15
134 S. Ct. at 2124. The Court thus does not find Williamson’s proposed construction unclear
16
because it sufficiently delineates the scope of the claim.
17
Therefore, in light of the specification and the claim language, the Court finds no
18
persuasive evidence that the request must contain location information and adopts Williamson’s
19
proposed construction.
20
21
22
C.
“location signal” (and variants)
Williamson’s Proposal
No construction necessary.
Google’s Proposal
“header referencing an
address”
Court’s Construction
No construction necessary.
23
The disputed phrase “location signal” appears in asserted independent claims 1, 20, 34, 64,
24
72 and 75 of the ’045 patent, and independent claims 1, 17, 39, and 44 of the ’698 patent. Claim 1
25
of the ’045 patent is representative of how the phrase is used in the claim language:
26
27
28
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:
9

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

Williamson argues that no construction is needed for “location signal” because it is a
readily understood phrase. According to Williamson, the specification places no restrictions
relating to the formatting of the signal or any other limitations. Opening Br. 13. Google,
however, urges this Court to construe the term in accordance with its proposal because the phrase
is by itself ill-defined and does not have a specialized technical meaning. Resp. Br. 6. Google
further argues construction is necessary in order to differentiate “location signal” from “location
address,” another phrase used in the claims.
The Court does not find “location signal” to be ill-defined or vague so to require a
construction. Construing a claim term or phrase is only required “when the meaning or scope of
technical terms and words of art is unclear and in dispute and requires resolution to determine the
issue before the court.” Eli Lilly and Co. v. Aradigm Corp., 376 F.3d 1352, 1360 (Fed. Cir. 2004).
Where “the ordinary meaning of claim language as understood by a person of skill in the art may
be readily apparent even to lay judges, claim construction in such cases involves little more than
the application of the widely accepted meaning of commonly understood words.” Phillips, 415
F.3d at 1314.
10
“Location signal” is neither a technical term nor word of art but instead has a plain and
1
2
ordinary meaning in light of the specification and in context of the claims. Google’s expert, Dr.
3
Freedman opines that “the term ‘location signal’ did not have a standard meaning to one of skill in
4
the art in 1997” or even now in 2017. Freedman Decl. ¶ 17, ECF 137-4. He also states that
5
“location signal” is “not a term of art.” Id. Further, Williamson’s expert, Dr. Almeroth, agrees
6
with this opinion that “location signal” did not have a standard meaning in 1997, and that a person
7
of ordinary skill in the art would readily understand this phrase in light of the specification.
8
Almeroth Decl. ¶¶ 22-23, ECF 138-3. These expert opinions on the lack of a “standard” meaning
9
do not persuade the Court that a construction is necessary. Rather, the Court finds these expert
opinions to be consistent with the conclusion that “location signal” is not a technical term or word

12
that construction is necessary to differentiate “location signal” from “location address.” However,
13
Google does not explain why the plain and ordinary meaning of those terms would be insufficient
14
to impart different meanings. 1
Lastly, Google proposes “header referencing an address” as a construction by cobbling
15
16
together various disclosures in the specification and in a draft specification for HTTP/1.1. Resp.
17
Br. 7-8; App. B to Freedman Decl., ECF 137-6. However, Google provides no valid reason why
18
the term needs to be limited by the disclosure in the specification or in the HTTP/1.1 draft
19
specification. Notably, “header referencing an address” does not appear anywhere in the patents-
20
in-suit. In addition, even though Google points to embodiments in the specification showing that
21
location signal is an HTTP response containing a header referencing an address, claim terms
22
normally should not be limited to embodiments in the specification. See Phillips, 415 F.3d at

Additionally, Google was adamant at the hearing that the claim phrase “location signal” must be
construed to “grapple” with serious problems that are forthcoming, including issues relating to
“distinguish[ing] the invention from the prior art.” June 16, 2017 H’rg Tr. 37:23-38:2. This
generic statement, however, fails to elucidate for the Court the relevance of these alleged problems
to claim construction. Further, as explained below, because the Court does not find Google’s

(except for terms appearing

The disputed phrase “counting each display of said specified banner on the client device”
appears in asserted dependent claims 71 and 73 of the ’045 patent, and independent claims 17 and
39 and dependent claims 2, 3, 24, and 25 of the ’698 patent. Claim 71 of the ’045 patent

ultimately depends on independent claim 64 and is set forth below as an example of how the
12
phrase is used:

15
16
71. The method of claim 70, including counting at least one display of said specified
banner on the client device.
’045 patent at 32:21-22 (emphasis added).
Williamson argues that no construction is needed for “counting at least one display of said
17
specified banner on the client device” because the plain and ordinary meaning is clear. Opening
18
Br. 14. According to Williamson, Google’s proposed construction requiring counting to occur at
19
the server and counting requests instead of displays is inconsistent with the claim language and the
20
specification. Id.
21
Google contends that the purported invention counts requests at the server, which is
22
acknowledged by Williamson when discussing relevant portions of the specification. Resp. Br. 9-
23
10. In order for the claim construction to be consistent with the specification, Google argues that
24
“counting displays” should be construed as “counting requests.” Id. at 10. Google also avers that
25
without construction, the literal language could only cover counting the actual display on the client
26
device and not requests at the server. Google then concludes that its proposed construction is
27
appropriate to “preserve [the claims’] validity” in light of the written description and enablement
28
issues. Id. at 10-11.
12
At the claims construction hearing, the Court ordered the parties to file supplemental briefs
1
to further aid this Court in construing this phrase. Williamson reiterates the position that the
3
phrase should not be limited to an embodiment disclosed in the specification. Pl. Supp. Br. 2,
4
ECF 147. It also highlights that a dependent claim, claim 24 of the ’698 patent, further limits the
5
claim scope of independent claim 17 by specifying that the counting is “done by said server.” Id.
6
According to Williamson, in light of such a dependent claim, limiting independent claims
7
containing the “counting” phrase to “counting at the server” would be contrary to principles of
8
claim construction. Id. (citing Phillips, 415 F.3d at 13). Google maintains its disagreement with
9
Williamson, and in its supplemental brief, provides specific variations of its proposed construction
10
for the asserted claims. Def. Supp. Br. 2, ECF 148. Google argues that its proposed construction
11
United States District Court
Northern District of California
2
does not limit the claims to a preferred embodiment but merely clarifies that “display” is
12
shorthand for ensuring that “an ad request could always be counted by the primary server.” Id. at
13
2.
14
The Court’s comments made during the claims construction hearing might have suggested
15
that at the time of the hearing, the Court was evaluating whether the “counting” phrase requires
16
construction. In an attempt to explore all sides of the parties’ argument, the Court suggested that
17
“display” may not have “a common meaning” and thus the phrase might require a construction.
18
Now with the benefit of an in-depth discussion on the record and further review of the parties’
19
supplemental submissions, the Court determines that the “counting” phrase need not be construed.
20
This is because its plain and ordinary meaning can be readily understood by a person of ordinary
21
skill in the art. While Google insists that the claimed invention counts requests at the server and
22
does not count displays, it also acknowledges that the specification discloses a system that
23
provides “for accurate monitoring and counting of the information and banners displayed to a user
24
or served to a terminal.” Resp. Br. 10 (citing ’045 patent at 3:21-28). The Court finds that such
25
disclosure supports the plain and ordinary meaning of this phrase. In an attempt to circumvent this
26
inconvenient disclosure in the specification, Google claims that the counting requests sent to the
27
server is a surrogate for counting the display at the terminal. Resp. Br. 10; Def. Supp. Br. 2.
28
However, this proposed “surrogate” construction is not apparent from the claim language itself
13
1
and Google offers no reason why a specific counting means disclosed in the embodiment –
2
counting requests at the server – must substitute for counting displays. Notably, dependent claim
3
24 of the ’698 patent requires in addition to the independent claim, “wherein said counting each
4
display of said specified banner on the client device is done by said server.” ’698 patent at 29:48-
5
50. The inclusion of this limitation of counting being “done by said server” makes it likely that
6
the patentee did not contemplate that “counting” as recited in the independent claim already
7
contained that limitation. See Phillips, 415 F.3d at 1324 (concluding that an independent claim
8
should be given broader scope than a dependent claim to avoid rendering the dependent claim
9
redundant) (citing Dow Chem. Co. v. United States, 226 F.3d 1334, 1341-42 (Fed. Cir. 2000)).
Regardless, the specification discloses a computer terminal that displays a banner by
10
United States District Court
Northern District of California
11
sending a request to a server, which responds by sending a banner location signal to the terminal,
12
which then responds by sending a second banner request, and which then receives and displays the
13
banner. The “counting” phrase could encompass counting banner display directly or indirectly by
14
counting any of these signal relays. Even if one or more of these counting means might be
15
imprecisely correlated with actual displays under certain circumstances, not enabled, or not
16
adequately supported by written description, these are not issues before the Court here. Rather,
17
the inquiry here is whether the plain and ordinary meaning of the phrase conveys what the phrase
18
would mean to a person of ordinary skill in the art in the context of the claim, and in light of the
19
specification and prosecution history. The Court concludes that the “counting” phrase is readily
20
understood by its plain and ordinary meaning and no construction is necessary.

INDEFINITENESS
A.
“best suited”
Williamson’s Proposal
No construction necessary.
Google’s Proposal
Indefinite.
Court’s Construction
No construction necessary.
The disputed phrase “best suited” appears in asserted dependent claim 7 of the ’045 patent.
Claim 7 of the ’045 patent is set forth below:
7. The method of claim 1, wherein after the primary server receives the first request signal
from the terminal, further including determining which server connected to the computer
network is best suited for serving said second portion of information to the terminal.
14

2
’526 Patent at 9:19-34 (emphasis added).
Williamson contends that claim 7 containing the phrase “best suited” is not indefinite
3
because the specification and claim language adequately inform persons of ordinary skill in the art
4
about the scope of the claimed invention. Opening Br. 16. Williamson further argues that the
5
phrase is not “vague or boundless” because the claim requires that the server be “best suited” to
6
perform a particular task of serving the requested information. Reply 7, ECF 140. Google
7
counters that the examples in the specification fail to render the claim definite because there
8
remains a limitless list of qualities one could consider to determine which server is “best suited.”

Resp. Br. 13.

“A patent is invalid for indefiniteness if its claims, read in light of the specification
United States District Court
Northern District of California
11
delineating the patent, and the prosecution history, fail to inform, with reasonable certainty, those
12
skilled in the art about the scope of the invention.” Nautilus, 134 S. Ct. at 2124. Proof of
13
indefiniteness requires an accused infringer to show “by clear and convincing evidence that a
14
skilled artisan could not discern the boundaries of the claim based on the claim language, the
15
specification, and the prosecution history, as well as her knowledge of the relevant art area.”
16
Halliburton Energy Servs., Inc. v. M-I LLC, 514 F.3d 1244, 1249-50 (Fed. Cir. 2008).
17
Here, Google has not met its burden to show by clear and convincing evidence that claim 7
18
is indefinite. First, the specification provides guidance on how to select a server that is “best
19
suited” for serving the requested information to a terminal. Criteria for determining a server that
20
is “best suited” includes shortest period of response time, network topological distance,
21
geographical distance, bandwidth of the server, and round trip times. See ’045 patent at 20:61-
22
21:7; 24:32-47. Although the claim is not limited to a particular factor or numerical limit, one of
23
ordinary skill in art could use these various factors to determine a server that is “best suited” for
24
serving the requested information. See C-Cation Techs., LLC v. Time Warner Cable, Inc., No. 14-
25
0059-JRG-RSP, 2015 WL 1849014, at *11 (E.D. Tex. Apr. 20, 2015) (finding no indefiniteness
26
with the phrase “determining whether a different and suitable signalling [sic] data channel is
27
available” because one skilled in the art would recognize various factors that could be used to
28
determine suitability).
15
1
Second, contrary to Google’s argument, case law does not mandate a patentee to set forth
2
in the claim specific means or metric for what constitutes “best suited” to meet the definiteness
3
requirement, as the Supreme Court noted, “[s]ome modicum of uncertainty [] is the ‘price of
4
ensuring the appropriate incentives for innovation.’” Nautilus, 134 S. Ct. at 2128 (citation
5
omitted); see also Sonix Tech. Co. v. Pubs. Int’l, Ltd., 844 F.3d 1370, 1377 (Fed. Cir. 2017)
6
(holding that “a patentee need not define his invention with mathematical precision in order to
7
comply with the definiteness requirement.”); id. at 1379 (noting that “requirements for the
8
graphical indicators being negligible to human eyes” render the claim definite). Moreover, claim
9
7 only requires that a determination is made, and does not require that the selected server must
meet various criteria with mathematical precision. See, e.g., Vstream Techs., LLC v. PLR
11
United States District Court
Northern District of California
10
Holdings, LLC, No. 15-974-JRG-JDL, 2016 WL 6211550, at *13 (E.D. Tex. Sept. 27, 2016)
12
(finding not indefinite the phrase “based upon which pipeline is more suitable for processing the
13
component” and noting that “the fact that the pipe analyzer performs the suitability analysis is the
14
important issue, not necessarily the outcome of that analysis”). Accordingly, that there are
15
numerous ways to meet this claim limitation, as argued by Google, does not alone make claim 7
16
indefinite.
17
Additionally, claim 7 does not simply require identifying a server that is best suited
18
without further qualifications. Rather, it requires “determining which server connected to the
19
computer network is best suited” for a specific purpose – “serving said second portion of
20
information to the terminal.” See Reply 7. Given the requirement that the server must be best
21
suited for “serving said second portion of information to the terminal,” the claim language viewed
22
in light of the specification adequately informs a person of ordinary skill in the art the scope of the
23
claim with reasonable certainty. See Nautilus, 134 S. Ct. at 2129 (holding that the test for
24
definiteness is whether the “patent’s claims, viewed in light of the specification and prosecution
25
history, inform those skilled in the art about the scope of the invention with reasonable certainty”).
26
The Court recognizes that merely providing examples in the specification does not always
27
render a claim definite, especially when the examples fail to inform a person of ordinary skill the
28
scope of the claims. E.g., Prolifiq Software Inc. v. Veeva Sys. Inc., No. 13-03644-SI, 2014 WL
16
3870016, at *6 (N.D. Cal. Aug. 6, 2014) (finding the term “differently versioned” rendered the
2
claims indefinite because specification “only provides information about when something is a
3
differently versioned digital content element, but it does not provide information about when
4
something is not a differently versioned digital content element”). However, aside from
5
conclusory assertions that one of ordinary skill in the art cannot discern the scope of the claim
6
without specific selection criteria, Resp. Br. 13-14, Google has not presented clear and convincing
7
evidence showing why these examples would be inadequate or why specific selection criteria
8
would be necessary. For example, Google has not presented any expert opinions on whether one
9
of ordinary skill in the art would be able to determine the scope or meaning of claim 7. Without
10
evidence on this point, Google cannot meet its burden of showing indefiniteness by the clear and
11

convincing standard.

Williamson argues that the claims in light of the specification and prosecution history
properly inform a person of ordinary skill in the art about the scope of the invention. Opening Br.
18. According to Williamson, the use of the word “intended” does not introduce a subjective
intent, but instead aims to convey that the signal “is designed in a way such that it will not be
blocked or prevented from reaching the primary server.” Id. at 18-19. Further, Williamson argues
that this phrase was the result of a claim amendment during prosecution where the patent examiner
found the prior claim requiring that the “signal cannot be blocked” as not enabled. Id. at 19-20.
Williamson concludes that the examiner’s eventual approval of the current claim language shows
that the claim is not indefinite.
Contrary to Williamson’s contention, Google avers that the claims require a subjective
intent, which would render the claims indefinite. Resp. Br. 14. Google highlights that the
examples disclosed in the specification, such as the use of “cgi-bin” and “?,” could have different
purposes, one to prevent the request from being blocked from reaching a server and another to
maintain session state across requests. Id. at 14-15. According to Google, only by weighing the
subjective intent of the designer would one be able to determine whether there is infringement. Id.
at 15. Google then concludes that such consideration of subjective intent renders the claims
indefinite. Id.
Google has not met its burden to show by clear and convincing evidence that claims
containing the phrase at issue are indefinite. Based on plain and ordinary meaning, information
“intended to prevent said first request signal from being blocked” simply refers to information that
is configured to prevent the request signal from being blocked. Further, when read in light of the
specification and the prosecution history, the requirement that the claims implicate subjective
intent is nowhere to be found. Nautilus, 134 S. Ct. at 2124. Although the Court does not defer to
18
1
the patent examiner’s findings that the claims are valid (separate from the general presumption of
2
patent validity), the prosecution history remains informative. See Quad Envtl. Techs. Corp. v.
3
Union Sanitary Dist., 946 F.2d 870, 876 (Fed. Cir. 1991) (“although courts may take cognizance
4
of, and benefit from, the proceedings before the patent examiner, the question is ultimately for the
5
courts to decide, without deference to the rulings of the patent examiner.”). The prosecution
6
history shows that the claim amendment incorporating the phrase containing “intended” was not to
7
introduce subjective intent, but to overcome an enablement issue.
8
The Court further finds that the use of the word “intended” on its own does not introduce
subjective intent in the context of the claims and the specification. Rather, the word “intended” is
10
often used to introduce a functional limitation to a claim, which is exactly the case here. In Caron
11
United States District Court
Northern District of California
9
v. QuicKutz, Inc., the court did not find ambiguous the use of the phrase “intended to be used for,”
12
and actually construed “embellishing template” as “a die having features intended to be used for
13
cutting, embossing, and/or stenciling on sheet media.” No. 09-02600, 2012 WL 5053232, at *2
14
(D. Ariz. Oct. 16, 2012). The motion for reconsideration of the claim construction order on the
15
basis of indefiniteness was denied. Id. In denying the motion for reconsideration, the court held
16
that the phrase “intended to be used for” did not render the claims ambiguous. Id. It further
17
reasoned that it was not necessary to decide who exhibited the intent and that it “can be
18
determined objectively whether a person skilled in the art would conclude that a die has an
19
opening or projection that will cut, emboss, and/or stencil in an intended shape or pattern.” Id.
20
Similarly here, the use of the word “intended” introduces a functional limitation in connection
21
with “information,” as recited in the claims and introduces no ambiguity. See, e.g., SourceOne
22
Global Partners, LLC v. KGK Synergize, Inc., 2010 WL 2232944, at *9 (N.D. Ill. June 3, 2010)
23
(construing the phrase “for treating breast cancer” to mean “intended to prevent or inhibit breast
24
cancer”); see also Ricoh Co., Ltd. v. Quanta Computer, Inc., 571 F. Supp. 2d 929, 937-38 (W.D.
25
Wis. 2007) (construing the phrase “to be accessed” to mean “intended for access in the future”).
26
In fact, Williamson represented to the Court at the hearing that the word “intended” could be
27
substituted with “designed” or “configured” without altering the meaning of the claims. These
28
means of reciting “intended,” “designed,” or “configured” to introduce a functional limitation do
19
1
not by themselves render the claims indefinite. Indeed, functional language may even promote
2
“definiteness because it helps bound the scope of the claims by specifying the operations” that the
3
claimed invention must undertake. Cox Commc’ns, Inc. v. Sprint Commc’n Co. LP, 838 F.3d
4
1224, 1232 (Fed. Cir. 2016); cf. Interval Licensing LLC v. AOL, Inc., 766 F.3d 1364, 1371-72
5
(Fed. Cir. 2014) (finding the claims containing the phrase “in an unobtrusive manner that does not
6
distract a user” indefinite because the phrase is “purely subjective” and the specification provides
7
no clarity).
8
Although the Court concludes that the plain and ordinary meaning of the disputed phrase
9
correctly conveys the meaning of the claims, substituting “intended” with “configured” would be
equally acceptable. In the event the parties find that replacing “intended” with “configured”
11
United States District Court

would be a proper construction and can assist the jury’s understanding of the disputed phrase, the
12
Court invites the parties to make that request.

“selecting the composition of said second portion of information”
Williamson’s Proposal
No construction necessary.

Court’s Construction
No construction necessary.
The disputed phrase “selecting the composition of said second portion of information”
appears in asserted dependent claim 14 of the ’045 patent. Claim 14 of the ’045 patent ultimately
depends on claim 1 and is set forth below.
14. The method of claim 4, including selecting the composition of said second portion
of information.
’045 patent at 28:22-23 (emphasis added).
Williamson contends that the claim 14 is not indefinite because the PTAB in a prior IPR
22
proceeding did not find it indefinite in the context of comparing the claim to the prior art.
23
Opening Br. 20-21. Williamson further argues that the patent specification adequately informs a
24
person of ordinary skill in the art. Id. at 21. Williamson notes that the patent explains that a
25
server may select the banner to be served and that the composition of the banner may be based on
26
demographics or other information about the user. Id.
27
Google urges this Court to find the claim indefinite because it is unclear which step of the
28
20
1
claimed method “select[s] the composition of said second portion of information.” Resp. Br. 17.
2
According to Google, the confusion stems from the direct dependence of claim 14 on claim 4,
3
referencing “a first request signal . . . ,” even though Williamson’s proffered support from the
4
specification referring to a different step that does not involve “a first request signal . . . .” Id.
5
Google also argues that the claim is indefinite on the additional ground that the specification
6
makes no mention of “the composition” of the banner. Id. at 17-18.
7
First, with respect to Google’s alleged confusion based on the dependence of claim 14 on
8
claim 4, there is no authority requiring a step recited in a dependent claim to be performed by the
9
step of an immediate parent claim. In other words, while claim 14 directly depends on claim 4 and
ultimately depends on claim 1, the “selecting” step in claim 14 does not have to necessarily occur
11
United States District Court
Northern District of California
10
at the same step as claim 4. Claim 4 does not even recite a method step but only specifies that the
12
“first request signal is a content general request signal,” further undercutting Google’s argument.
13
Second, as to whether the specification makes a mention of “the composition,” there is no
14
authority, and Google has provided none, requiring that the recited word or phrase must appear in
15
the specification as a condition for definiteness. Cf. Ariad Pharm., Inc. v. Eli Lilly & Co., 598
16
F.3d 1336, 1352 (Fed. Cir. 2010) (noting that the “description requirement does not demand any
17
particular form of disclosure, or that the specification recite the claimed invention in haec verba”)
18
(citation omitted). Accordingly, Google fails to meet the burden of showing by clear and
19
convincing evidence that claim 14 is indefinite.

Court’s Construction
“said banner”
The disputed phrase “said specified banner” appears in asserted independent claim 20 of
the ’045 patent. Claim 20 of the ’045 patent is set forth below.
20. A method for distributing a banner over a computer network to a device when the
banner is referenced or linked to in a document served to the device, wherein the
banner is stored in one or more servers, comprising:
receiving a first banner request signal from a device at a first server requesting that
a banner be served to the device, wherein said first banner request signal includes
21
1
2
information intended to prevent said first banner request signal from being blocked
from reaching said first server by the device despite previous caching of said
specified banner in the device;
4
sending a banner location signal from said first server to the device, wherein said
banner location signal includes location information for a specified banner stored

’045 patent at 28:38-55 (emphasis added).
Even though Williamson does not dispute that “said specified banner” lacks explicit
antecedent basis, it argues that a person of ordinary skill in the art could still ascertain the scope of
the invention based on the patent. Opening Br. 21-22. Further, Williamson points out that the
prior recitation of “a banner” provides the antecedent basis at least by implication. Id. at 22.
Williamson argues that the specification provides further support that “said specified banner”
refers to the previously recited “a banner.” Id.
Google counters that the portion of the specification relied upon by Williamson shows that
the meaning of this phrase is uncertain. Resp. Br. 18. Specifically, the specification states that the
initial banner request signal “either request[s] that unspecified banner be served to the terminal or
that a specified banner be served to the terminal.” Id. (citing ’045 patent at 4:4-10). Because it is
unclear which of these two options, one for unspecified banner and another for specified banner,
the phrase refers to, Google concludes that the claim is indefinite.
The Court agrees with Williamson and finds that claim 20 is not indefinite because of the
phrase “said specified banner.” The lack of an explicit antecedent basis is but a minor drafting
error in the claim, and the construction of this phrase is not subject to reasonable debate. Reading
the claim in light of the specification, and considering the claim as a whole, one of skilled in the
art would understand with reasonable certainty that the phrase “said specified banner” refers to the
previously recited “a banner.” Google argues that alternatively, the initial recitation of “a banner”
could be amended to “a specified banner,” and having this plausible alternative choice renders the
claim indefinite. However, this alternative amendment is not supported by the specification and is
inconsistent with other claims. The specification discloses that an initial banner request signal can
22
1
request either a specified or unspecified banner be served. ’045 patent at 4:4-10. This shows that
2
the scope of the invention could encompass either specified or unspecified banner and does not
3
support the narrower amendment of “a specified banner.” Moreover, claim 24, a dependent claim
4
of claim 20, requires that the first banner request signal be “a content general banner request
5
signal.” ’045 patent at 28:66-67. Amending claim 20 from “a banner” to “a specified banner”
6
would conflict with claim 24, and would not be a proper amendment. See, e.g., Phillips, 415 F.3d
7
at 1315 (“the presence of a dependent claim that adds a particular limitation gives rise to a
8
presumption that the limitation in question is not present in the independent claim”). As such,
9
Google has not provided clear and convincing evidence that claim 20 is indefinite.
10
Having found no indefiniteness, the Court turns to whether the first instance of the phrase
United States District Court
Northern District of California
11
“said specified banner” should be amended to “said banner.” A court may correct an error in a
12
claim “only if (1) the correction is not subject to reasonable debate based on consideration of the
13
claim language and the specification and (2) the prosecution history does not suggest a different
14
interpretation of the claims.” Novo Indus., L.P. v. Micro Molds Corp., 350 F.3d 1348, 1354 (Fed.
15
Cir. 2003). As discussed above, the correction here is not subject to reasonable debate based on
16
the claim language and the specification. The parties also do not argue that the prosecution history
17
suggests a different interpretation. One of ordinary skill in the art would also interpret this phrase
18
to be “said banner.” Accordingly, the Court construes the phrase to be “said banner” and the
19
corrected claim 20 is set forth below:
20

20. A method for distributing a banner over a computer network to a device when the
banner is referenced or linked to in a document served to the device, wherein the
banner is stored in one or more servers, comprising:
receiving a first banner request signal from a device at a first server requesting that
a banner be served to the device, wherein said first banner request signal includes
information intended to prevent said first banner request signal from being blocked
from reaching said first server by the device despite previous caching of said
specified banner in the device;
sending a banner location signal from said first server to the device, wherein said
banner location signal includes location information for a specified banner stored
on a second server; and
receiving a second banner request signal from the device at said second server
23
requesting that the second server serve said specified banner to the device.
