and Kassab (US 2006/0031404 A1, published Feb. 9, 2006) (“Kassab”).
Final Act. 4.
There are two independent claims on appeal, claims 1 and 11. Claim 1
is an apparatus claim that is configured to carry out a method. Claim 11 is a
method claim which recites substantially the same method steps recited in
claim 1. Claim 1, annotated with bracket numbering, is reproduced below:
1. An apparatus provided at a network providing
communication between an end user device and one or more
servers capable of responding to requests from the end user
device, the apparatus comprising processing circuitry
configured to, when executed:
Appeal 2019-006634
Application 15/138,918

3
[1] intercept a request from the end user device and
transmitted via the network;
[2] determine whether a response to the request will
include advertizing content based on a destination of the
request;
[3] intercept the response based on the determination;
[4] modify the response to modify source indicia of the
advertizing content in a modified response; and
[5] enable the modified response to be provided to the
end user device to effectively relay the advertizing content from
a different source.

CLAIM INTERPRETATION
We begin with claim interpretation because before a claim can be
compared to the prior art, it must be properly interpreted.
During patent examination proceedings, claim terms are given their
“broadest reasonable meaning . . . in their ordinary usage as they would be
understood by one of ordinary skill in the art, taking into account whatever
enlightenment by way of definitions or otherwise that may be afforded by
the written description contained in the applicant’s specification.” In re
Morris, 127 F.3d 1048, 1054 (Fed. Cir. 1997).
The first step of claim 1 recites “intercept a request from the end user
device and transmitted via the network.” The “intercept” is accomplished by
the “apparatus provided at a network providing communication between an
end user device and one or more servers capable of responding to requests
from the end user device.”
The Specification does not define the term “intercept.” We thus adopt
its ordinary dictionary definition to mean “to stop, seize, or interrupt in
Appeal 2019-006634
Application 15/138,918

4
progress or course or before arrival.”2 Therefore, we interpret “intercept” in
the claim to indicate that the request (step [1]) and response (step [3]) are
interrupted and seized before being transmitted to their destinations –
namely, the server in step [1] and the end user device in step [3],
respectively.
A determination is made in step [2] by the apparatus whether the
intercepted request (step [2]) will include advertising content. This
determination is made based on its destination. The Specification explains
that the destination may be a known or blacklisted “ad server.” Spec. ¶ 46.
If the destination is an ad server, the Specification further discloses that
“then the response may be awaited for interception.” Id. Step [3] of the claim
consistently recites “intercept the response” from the server “based on the
determination.” Thus, the response from the server to the request is only
intercepted if the determination is made that the response will contain
advertising.
In step [4] of the claim, the response is modified by the apparatus “to
modify source indicia of the advertizing content in a modified response.”
The response is enabled in step [5] “to be provided to the end user device to
effectively relay the advertizing content from a different source.” However,
as the Examiner correctly stated, the claim does not require the response to
be provided to the end user device, only that it be “enable[d]” to do so. The
Appeal Brief identifies operation 240 of Fig. 3, and lines 17–18 of paragraph
46 as support for the “enable” limitation. Appeal Br. 2. However, none of
this cited disclosure defines or explains how the “enable” step is

accomplished. Thus, in the context of the claim and Specification, we
interpret “enable” to mean that the recited “apparatus comprising processing
circuitry” is “configured to” provide the modified response back to the end-
user after it has been modified in step [4.]

REJECTIONS
The Examiner found that Leigh describes all the steps of the claimed
method. Final Act. 2–3. Specifically, the Examiner found that the proxy
server 111 of Leigh receives requests from a web client 101, meeting the
limitation of step [1] of claim 1 of “intercept a request from the end user
device and transmitted via the network.” Final Act. 2; Leigh § 19. The
Examiner further found that Leigh describes transmitting the request to
target web server 120. Final Act. 2; Leigh § 19. The Examiner also found
that Leigh at § 19 describes [2] “determine whether a response to the request
will include advertizing content based on a destination of the request” and
[3] “intercept the response based on the determination.” Final Act. 2.
The Examiner cited Leigh’s disclosure of an Ad Insertion Module
125, which “takes as input an HTML page (typically provided from a target
web server 120) and modifies it so that the web client (browser) is instructed
to request advertising content from an Ad Content Server 112 . . . by
inserting a code fragment into the HTML page” (Leigh § 21), as meeting
step [4] of claim 1 to “modify source indicia of the advertizing content.”
Final Act. 2 (see also Leigh § 22 which describes the actual replacement of
the advertising material).

With respect to step [5] of “enable the modified response to be
provided to the end user device,” the Examiner cited Leigh ¶ 22. Final Act.
2.
Appellant argues that Leigh’s description of a proxy server that
receives an HTTP request from a web client is “nothing more than a well-
known and conventional response to an HTTP request by a proxy server”
and does not meet the claim limitation of an “intercept” as recited in steps
[1] and [3]. Appeal Br. 5. Appellant further argues that the “proxy server is
the intended recipient of each HTTP request and does no interception of any
kind.” Id.
This argument is not persuasive. Appellant has not provided a
definition of “intercept” which would distinguish it from the disclosure in
Leigh of “Proxy server 111” as “an HTTP proxy server, which is a software
agent responsible for accepting TCP/IP connections from a web client 101,
receiving a HTTP request on behalf of the client, and then re-transmitting
that request to a target web server 120.” Leigh ¶ 19. We interpreted
“intercept” to mean that the request (step [1]) and response (step [3]) are
interrupted and seized before being transmitted to the server in step [1] and
the end user device in step [3], respectively. See supra at 3–4. The HTTP
proxy server receives the request and then re-transmits it, indicating that the
request is interrupted and seized by the server before re-transmitting it.
Appellant did not provide evidence that the claimed “intercept” step requires
that the proxy server is not the “intended” recipient of the request. Appeal
Br. 5. Furthermore, Leigh expressly teaches that requests are intercepted: “In
one embodiment, a request from the web client for the web page is
intercepted and used to retrieve the web page from the target web site.”
Appeal 2019-006634
Application 15/138,918

Leigh ¶ 4; see also Leigh ¶ 52. Thus, we find Appellant’s argument to be
unavailing.
Appellant also argues that Leigh does not describe the steps of [2]
“determine whether a response to the request will include advertizing
content based on a destination of the request” and “[3] intercept the response
based on the determination.” Appeal Br. 5.
We agree with Appellant that the Examiner did not provide adequate
evidence that steps [2] and [3] of claim 1 are described by Leigh. We
interpreted these steps to require that the response to the request from the
server is only intercepted if the determination is made that the response will
contain advertising. See supra at 4. The Examiner cited Leigh ¶ 19 for
disclosing these steps. Ans. 4 (citing ¶¶ 19–27).
Paragraph 19 of Leigh discloses “[w]hen the target web server returns
a response to the proxy server 111, that response is then in turn delivered to
the requesting web client/browser 101.” This disclosure does not indicate
that the response is intercepted only when it is determined that it has ad
content as required by steps [2] and [3] of the rejected claim; rather, it is
intercepted in all cases and without any determination having been made of
ad content. Similarly, in paragraph 20, Leigh teaches “Proxy server 111
passes HTML content that has been returned by the target web server to an
Ad Insertion Module 125 (described below) before returning the HTML
content to the user,” but makes no mention that the interception is only
accomplished when an ad content determination is made.
In the following paragraphs, Leigh describes how ad content is
inserted. Leigh ¶¶ 21, 22. While this disclosure meets the requirement of
Appeal 2019-006634
Application 15/138,918

8
steps [4] and [5] of claim 1, it does not disclose that a determination is first
made by the proxy server before intercepting the HTML page.
Leigh further explains “a request from web client/browser 101 is
received by proxy server 111 and sent to target web server 120.” Leigh ¶ 27.
Next, “HTML web page 200(1) is then sent from target web server 120 to
proxy server 111, in response to the web client request for the web page.” Id.
The web page is then “returned to the requesting web client 101.” Id. This
disclosure makes it clear that no determination is made on whether a
response to the request will include advertizing content based on a
destination of the request as required by all the rejected claims. Instead, the
proxy server indiscriminately intercepts requests from the client and from
the target web server without making a determination on whether the initial
request will include advertising content.
The additionally cited publications by Lin, Hudson, Lee, and Kassab
were not found by the Examiner to describe or suggest steps [2] and [3] of
claim 1.
Accordingly, for the foregoing reasons, the anticipation rejection of
claim 1 and dependent claims 8 and 18 is reversed. Claim 11 has
substantially the same limitations as claim 1,3 and therefore the anticipation
rejection of claim 11 is reversed.
The obviousness rejection of claims 2, 3, 12, and 13 based on Leigh
and Lin is also reversed because the Examiner did not find that Lin makes
up for the deficiencies in Leigh.

3 “determining whether a response to the request will include advertizing
content based on a destination of the request; intercepting the response based
on the determination.”

Application 15/138,918

9
The obviousness rejection of claims 4–6 and 14–16 based on Leigh
and Hudson is also reversed because the Examiner did not find that Hudson
makes up for the deficiencies in Leigh.
The obviousness rejection of claims 7, 9, 17, and 19 based on Leigh
and Lee is also reversed because the Examiner did not find that Lee makes
up for the deficiencies in Leigh.
The obviousness rejection of claims 10 and 20 based on Leigh and
Kassab is also reversed because the Examiner did not find that Kassab
makes up for the deficiencies in Leigh.
