I. INTRODUCTION
Petitioner Unified Patents Inc. (“Unified”) requests Inter Partes Review
(“IPR”) of claims 1, 2, 7, 27, 28, 29, 34, 54, 72, 73, 74, 92, 93 and 111 of U.S.
Patent No. 8,542,815 (“the ’815 patent”) assigned to Digifonica (International)
Limited (“Digifonica”) (EX1001).
The ’815 patent has a filing date of March 1, 2010, and is a § 371 national
stage application of PCT no. PCT/CA2007/001956, filed November 1, 2007. This
application claims priority to U.S. provisional application no. 60/856,212, filed
November 2, 2006. The ’815 patent describes a process and apparatus for
facilitating communication between callers and callees in a system that generates
routing messages identifying private network addresses or public network
gateways. EX1001 at Abstract. The ’815 patent alleges that the invention relates to
voice over IP (“VoIP”) communication, id. at 12–13, though the independent
claims are not so limited. EX1002 ¶¶ 23, 24. The ’815 patent suggests that it
uniquely fills gaps in bridging communication between private networks (such as
VoIP networks) and public networks such as Public Switched Telephone Networks
(“PSTN”). The ’815 patent states:
Existing VoIP systems do not allow for high availability and
resiliency in delivering Voice Over IP based Session Initiation
Protocol (SIP) Protocol service over a geographically dispersed area
such as a city, region or continent. Most resiliency originates from the
IPR2016-01082Patent 8,542,815
2
provision of IP based telephone services to one location or a small
number of locations such as a single office or network of branch
offices.
Id. at 1:40–46.
Technologies that enable public and private communication network
connections have long been well-known in the art. The claimed “public network”
includes, for example, a PSTN, which has existed, in evolving forms, for more
than a century—i.e., since the invention of the telephone in 1876.1 The claimed
“private network” includes private phone networks or Internet Protocol networks
that use VoIP communication protocols. These types of networks were invented
more than twenty years ago—at least a decade prior to the ’815 patent priority
date. 2 Moreover, a plethora of systems connecting VoIP private networks and
PSTN public networks have existed since well before the ’815 patent. One good
example, U.S. Patent No. 8,594,298 to Klein et al. (“Klein”, attached as EX1006)
1 EX1007: Livengood, Daniel, et al. “Public Switched Telephone Networks: A
Network Analysis of Emerging Networks. Massachusetts Institute of Technology,
submitted May 16, 2006, pg. 5-6.
2 EX1008: Hallock, Joe, “A Brief History of VoIP: Document One - The Past,”
Evolution and Trends in Digital Media Technologies - COM 538, University of
Washington, November 26, 2004, pg. 7.
IPR2016-01082Patent 8,542,815
3
discloses such a system. Klein, which was filed on February 20, 2004, and
published on September 15, 2005, and discloses connecting PSTN 103 to PBX
104C (Private Branch Exchange) in figures 1 and 14. Thus, these types of networks
and connections existed long before the ’815 patent claims to have invented them,
providing motivation to interconnect individual users through the various methods
of known communication networks. EX1002 ¶ 24.
Other features of the ’815 patent, such as the use of caller profiles and
“attributes” associated with callers, are at least as old as the decades-old VoIP
technology. Indeed, the ’815 patent specification itself concedes that “attributes”
contained in caller profiles consist of standard information such as location codes,
country codes, and international dialing digits. EX1001 at 18:1–54. In other words,
technologies using the claimed types of information were widely known prior to
the application for the ’815 patent and its priority date. EX1002 ¶¶ 25, 26.
Years before the ’815 patent’s effective filing date, a myriad of prior art
patents and printed publications disclosed the claimed combination of elements,
though we are limited to addressing just a few good examples. As this petition
demonstrates, the disclosures of Turner (EX1003) and Kaczmarczyk (EX1004),
among other patents and publications, warrant the cancellation of claims 1, 2, 7,
27, 28, 29, 34, 54, 72, 73, 74, 92, 93 and 111.

II. MANDATORY NOTICES
A. Real Party-in-Interest
Pursuant to 37 C.F.R. § 42.8(b)(1), Petitioner certifies that Unified is the real
party-in-interest, and further certifies that no other party exercised control or could
exercise control over Unified’s participation in this proceeding, the filing of this
petition, or the conduct of any ensuing trial. In this regard, Unified has submitted
voluntary discovery. See EX1009 (Petitioner’s Voluntary Interrogatory
Responses).
B. Related Matters
Upon information and belief, the ’815 patent has been thus far asserted in
the following cases: Voip-Pal.com, Inc. v. Verizon Wireless Services, LLC &
AT&T Corp., 2-16-cv-00271 (D. Nev. Feb. 9, 2016), and Voip-Pal.com, Inc. v.
Apple, Inc., 2-16-cv-00260 (D. Nev. Feb. 9, 2016). VoIP-PAL.com, Inc., in a
public press release filed on February 11, 2016, announced it seeks to monetize
this and one other patent for over $7 billion in damages. See EX1010.
C. Lead and Back-Up Counsel, and Service Information
The signature block of this petition designates lead counsel, backup counsel,
and service information for each petitioner. Unified designates P. Andrew Riley
(Reg. No. 66,290) as lead counsel and designates Kai Rajan (Reg. No. 70,110) as
backup counsel. Both can be reached at Finnegan, Henderson, Farabow, Garrett &
Dunner, LLP, 901 New York Avenue, NW, Washington, DC 20001-4413 (phone:

C. The Level of Ordinary Skill in the Art at the Time of the Claimed Invention
The ’815 patent ultimately claims priority to U.S. Provisional Application
No. 60/856,212, filed November 2, 2006. At that time, a person having ordinary
skill in the art (hereafter, “POSA”) of telecommunication (i.e., in the art for the
’815 patent) would have (i) a B.S. degree in computer engineering, electrical
engineering, computer science, or equivalent field, and (ii) approximately two
years of experience or research on switched circuit telephony and packetized
telephony, such as VoIP. See EX1002 at ¶ 28.
V. THE ’815 PATENT
A. Overview of the Disclosure
The ’815 patent describes a process and apparatus for facilitating
communication between callers and callees by generating routing messages
identifying private network addresses or public network gateways. EX1001 at
Abstract.
The ’815 patent alleges that the invention relates to voice over IP (“VoIP”)
communication (Id. at 12–13), though the independent claims are not so limited.
In the specification, the ’815 patent describes the general process for the
invention as involving (1) receiving a callee identifier [such as a dialed number]
from a calling subscriber, (2) classifying the call as a public network or private
network call using criteria [attributes] associated with the calling subscriber, and
IPR2016-01082Patent 8,542,815
7
(3) producing a routing message identifying either a private network address or a
public network gateway. EX1001 at 14:24–35, EX1002 ¶ 21. The ’815 patent
specification concedes that “attributes” contained in caller profiles include standard
information such as location codes, country codes, and international dialing digits.
EX1001 at 18:1–54, EX1002, ¶ 25.
The ’815 patent describes “dialing profiles” that can contain criteria
associated with the calling subscriber that is used to classify the call. Figure 9 of
the ’815 patent (reproduced below) shows an example of a dialing profile. As
shown, a dialing profile can include information such as a country code or local
area codes associated with a caller, a username, a domain of the caller,
international dialing digits (IDD), and national dialing digits (NDD) associated
with the caller.
Thus, the dialing profile
identifies where the caller is located and
the numbers the caller would need to
dial to make a local, national, or
international call.
Once a call is placed, a routing controller
receives a message such as a Session Initiation
Protocol (SIP) message having information such
IPR2016-01082Patent 8,542,815
8
as the number or ID of the caller, and the dialed number/ID of the callee, as shown
in Fig. 3 of the ’815 patent:
The system looks up information associated with the caller (such as the
caller ID/number in the dialing profile), and proceeds to identify matches between
the caller ID and the callee ID. For example, the phone numbers of the caller and
callee can be compared to determine whether there is a match in area codes or a
portion of the caller and callee usernames. As another example, certain dialed
digits can be recognized as initiating an international call, depending on the IDD
information associated with the caller. EX1001 at 21:8–22:60. The identified
matches are then classified using public/private criterion to determine whether the
call is a public network or private network call. Id. at 22:48–23:3. The system then
generates a routing message for the private or public call, and transmits the routing
message. Id. at 24:18–67, 26:37–45.
B. Prosecution History
The application was filed on April 30, 2009, EX1005 at 880–1,166, but was
granted a § 371 date of March 1, 2010. Id. at 847. The application was filed as a
national stage application of PCT No. PCT/CA2007/001956, with the PCT
claiming the priority of U.S. provisional application No. 60/856,212, filed
November 2, 2006. Id. at 911. Thus, the ’815 patent may have an effective filing
date of November 2, 2006, provided it contains and maintains full support in the
IPR2016-01082Patent 8,542,815
9
provisional application.
The Examiner opened prosecution in March 2013, by rejecting the original
fifty-nine claims under 35 U.S.C. § 102. EX1005 at 154–178. In response, the
applicant amended all of the pending independent claims to incorporate multiple
dependent claims, cancelled the incorporated dependent claims, and added 58 new
claims to the remaining claims. Id. at 95–136. The Examiner conducted a search
confined to specific terminology or specific patent subclasses. Id. at 88 (Ref. Nos.
S1–S13). In July 2013, the Examiner mailed a Notice of Allowance including an
Examiner’s Amendment that narrowed the scope of the independent claims. Id. at
54–81. There, the Examiner declared that the allowable subject matter in the
independent claims consisted of “matching one of calling attributes, retrieved from
a calling party’s profile, with at least a portion of a callee identifier, and based on
the match [identifying] a public or private network for call routing.” Id. at 80.
Notably, the “allowable subject matter” was first added to the independent claims
in the Examiner’s Amendment. Id. at 54–81.
VI. GROUNDS FOR STANDING
Unified certifies that the ’815 patent is available for IPR and it is not barred
or estopped from requesting IPR challenging the ’815 patent on the grounds
identified. See 37 C.F.R. § 42.104(a). Specifically: (1) Unified is not the owner of
the ’815 patent; (2) Unified is not barred or estopped from requesting IPR; and (3)
IPR2016-01082Patent 8,542,815
10
Unified has not been served with a complaint alleging infringement of the ’815
patent.
A. Claim Construction
Claim terms are given their ordinary and customary meaning as understood
by a POSA. Phillips v. AWH Corp., 415 F.3d 1303, 1312-13 (Fed. Cir. 2005) (en
banc). A claim in an unexpired patent subject to inter partes review receives the
“broadest reasonable construction in light of the specification of the patent in
which it appears.” 37 C.F.R. § 42.100(b). The majority of the claims are common
terms that deserve their ordinary and customary meaning. Unified suggests the
following terms from the claims of the ’815 patent require construction.3
“Caller dialing profile” 1.
Independent claims 1, 27, 28, 54, 73, 74, and 93 all specify that a “caller
dialing profile” is accessed or located, and the caller dialing profile comprises “a
plurality of calling attributes associated with the caller.” EX1001 at 36:20-22,
38:33-35, 60-62, 41:28-29, 43:20-22, 27-31, and 45:31-32. The specification
discusses the “caller dialing profile” or “dialing profile” with multiple examples.
3 The broadest reasonable interpretation should be applied to any claim terms not
addressed below, though Unified believes a claim construction under either a
Phillips standard or an interpretation under the broadest reasonable construction
are consistent.
IPR2016-01082Patent 8,542,815
11
For example, with respect to Fig. 9, the ’815 patent discusses a “data structure for a
dialing profile” which can include a “user name field,” a “domain field” and
“calling attributes.” EX1001 at 17:59-18:4, Fig. 9. The specification further states
that “dialing profiles represent calling attributes of respective subscribers.” Id. at
18:3-4.
Taking into account the examples of information included in the “caller
dialing profile” in the specification, and the inventor’s characterizations in the
specification, the term “caller dialing profile” should be construed to mean
“information associated with a caller.” This construction is consistent with the
breadth of the various examples of data that is associated with the caller in the ’815
patent.
“Calling attributes” 2.
Independent claims 1, 27, 28, 54, 73, 74, and 93 all specify that a caller
dialing profile comprises “a plurality of calling attributes associated with the
caller.” EX1001 at 36:21-22, 38:34-35, 62, 41:29, 43:20-22, 28-29, 45:32. The
specification does not define the term “calling attributes,” and merely provides
examples such as “national dialing digits (NDD) . . . an international dialing digits
(IDD) . . . a country code . . . a local area codes . . . a caller minimum local
length . . . a caller maximum local length . . . a reseller . . . a maximum number of
IPR2016-01082Patent 8,542,815
12
concurrent calls . . . and a current number of concurrent calls.” EX1001 at 17:62–
67, FIGS. 9, 10.
Considering the specification’s examples of information related to called
numbers or call statistics, coupled with the lack of any explicit definition of the
term in the specification, the term “calling attributes” can reasonably be construed
to mean “information associated with a user, calls placed by the user, or calls
directed toward the user.”
“Means for receiving” 3.
“Means for receiving” is a means-plus-function term in claim 28 (EX1001 at
38:57) that invokes 35 U.S.C. § 112, 6th paragraph. Broadly and reasonably, the
specification may provide the following structure to provide the claimed
“receiving” function: a call controller circuit 100 that receives messages (such as
an SIP message) via an input 108. See EX1001 at 15:63–64; 16:2–8.
“Means for locating a caller dialing profile” 4.
“Means for locating a caller dialing profile” is a means-plus-function term in
claim 28 (EX1001 at 38:60) that invokes 35 U.S.C. § 112, 6th paragraph. Broadly
and reasonably, the specification may provide the following structure to provide
the claimed “locating a caller dialing profile” function: RC processor circuit (200).
See EX1001 at 17:46–56, Fig. 7.
IPR2016-01082Patent 8,542,815
13
“Means for determining a match” 5.
“Means for determining a match” is a means-plus-function term in claim 28
(EX1001 at 38:63) that invokes 35 U.S.C. §112, 6th paragraph. Broadly and
reasonably, the specification provides the following structure to provide the
claimed “determining a match” function: Processor 202 of RC processor circuit
200. See EX1001 at 19:50–55, FIGS. 5B, 7.
“Means for classifying the call” 6.
“Means for classifying the call” is a means-plus-function term in clam 28
(EX1001 at 38:66, 39:1) that invokes 35 U.S.C. §112, 6th paragraph. Broadly and
reasonably, the specification may provide the following structure to provide the
claimed “classifying the call” function: Processor 202 of RC processor circuit 200.
See EX1001 at 22:51–55, FIG. 7.
“Means for producing a [public/private] network routing 7.message”
“Means for producing a [public/private] network routing message” is a
means-plus-function term in claims 28 and 93 (EX1001 at 39:4, 8, 45:36, 44) that
invokes 35 U.S.C. § 112, 6th paragraph. Broadly and reasonably, the specification
may provide the following structure to provide the claimed “producing a
[public/private] network routing message” function: Processor 202 of the RC
processing circuit 200. See EX1001 at 17:40–43, 20:39–40.
IPR2016-01082Patent 8,542,815
14
“Means for accessing a database” 8.
“Means for accessing a database” is a means-plus-function term in claim 93
(EX1001 at 45:30) that invokes 35 U.S.C. § 112, 6th paragraph. Under the
broadest reasonable construction standard, the specification provides the following
structure to provide the claimed “accessing a database” function: RC processing
circuit 200. See EX1001 at 17:46–56.
“Means for formatting said callee identifier” 9.
“Means for formatting said callee identifier” is a means-plus-function term
in claim 34 (EX1001 at 39:40) that invokes 35 U.S.C. § 112, 6th paragraph.
Broadly and reasonably, the specification may provide the following structure to
provide the claimed “accessing a database” function: Processor 202 of the RC
processing circuit 200. See EX1001 at 19:55–60.
“Means for causing the private network routing message or the 10.public network message to be communicated to a call controller”
“Means for causing the private network routing message or the public
network message to be communicated to a call controller” is a means-plus-function
term in claim 111 (EX1001 at 47:22-25) that invokes 35 U.S.C. § 112, 6th
paragraph. Broadly and reasonably, the specification provides the following
structure to provide the claimed “causing the . . . message to be communicated”
IPR2016-01082Patent 8,542,815
15
function: Processor 202 of the RC processing circuit 200. See EX1001 at 24:65–
67.
VII. CLAIMS 1, 2, 7, 27, 28, 29, 34, 54, 72, 73, 74, 92, 93 and 111 OF THE ’815 PATENT ARE ANTICIPATED UNDER 35 U.S.C. § 102(e) AND/OR UNPATENTABLE UNDER 35 U.S.C. § 103(a)
A. Turner is Prior Art Under 35 U.S.C. § 102(e)
U.S. Patent No. 7,218,722 B1 (EX1003, “Turner”), was filed on December
18, 2000, and is prior art under at least 35 U.S.C. § 102(e) based on at least its
filing date. Turner predates the earliest priority date claimed in the ’815 patent
(November 2, 2006) by more than six years.
B. Kaczmarczyk is Prior Art Under 35 U.S.C. § 102(b)
U.S. Patent No. 6,961,334 B1 (EX1004, “Kaczmarczyk”), filed on March 29,
2001, was patented on November 1, 2005. Kaczmarczyk is prior art under 35
U.S.C. § 102(b) because it was patented/published more than a year before the
earliest priority date claimed in the ’815 patent (November 2, 2006).
C. Ground 1: Turner anticipates claims 1, 2, 7, 27, 28, 29, 34, 54, 72, 73, 74, 92, 93 and 111 under 35 U.S.C. 102(b)
Turner discloses a computerized method and system for routing calls
between parties at different locations. EX1003, Abstract. Calling and called parties
can be located on private networks such as Internet Protocol networks connected to
a gateway, or on public networks such as a PSTN. EX1003, FIG. 1, EX1002 ¶ 36.
IPR2016-01082Patent 8,542,815
17
profile data. Id. at FIG. 3, EX1002 ¶ 38.
The user profile and linked network address object (data structure) include
information associated with the caller such as a customer address (CA) and
network address (NA). EX1003 at 7:29–61. The network address and customer
address include information such as a telephone number or number indicative of a
location of the caller. Id. at 9:13–36, 10:25–53. For example, the CA and NA are
indicative of a network in which the caller is located, a gateway associated with the
caller, and/or a location of the caller. Id. The NA can be updated to reflect a current
location if the caller roams to a new location. Id. at 22:2–8. Thus, the data stored
and accessed by the Directory Server for a caller includes data associated with the
caller (caller attributes) such as addresses and preferences. EX1002 ¶ 39.
After retrieving the caller’s profile, the call agent determines whether the
called party is within the same gateway as the caller. EX1003 at 9:24–36. Turner’s
example discusses translating a called CA number to a NA, such as by translating
“2002” to “313-555-2002.” Id. The translated NA is then compared to the caller
number (313-555-2001), and the call agent determines that the matching numbers
(“333-555”) indicate that the caller and callee are within the same gateway. Id.
Another example from Turner discusses that a caller may dial a number
(3001), and that the call agent may assign the NA identifying the caller as “313-
555-2002.” EX1003 at 10:25–48. The call agent then queries the Directory Server,
IPR2016-01082Patent 8,542,815
18
which retrieves a user profile for the caller and translates the dialed number (3001)
to a NA for the callee—in this example it is “709-555.” Id. Based on the NA, the
call agent recognizes the network locations of the caller and callee and recognizes
that the called party is within the private network but is located on a different
gateway. Id. Thus, the call agent determines matches between the numbers in the
callee and caller information, as well as locations of the numbers based on stored
information associated with the caller and callee numbers (e.g., attributes).
EX1002 ¶ 41.
Based on the analysis of the NA and/or CA of the caller and the callee, as
well as stored information associated with the NA and CA, the call agent of Turner
determines whether the callee is within the same gateway as the caller and can be
processed internally, such as a private network call. EX1002 ¶ 42. The call agent
also determines whether the call is directed toward a
callee on another gateway, such as a public network
call. EX1003 at 9:30–36, FIG. 4A (portion reproduced
to the right). Therefore, the call agent classifies the call as a private network call or
a public network call. EX1002 ¶ 42.
In addition to the analysis of the CA and NA, the Directory Server analyzes
the called address to identify codes or digits that are associated with the caller as
being numbers for “private trunk network access” or “escape to the PSTN.”

address attribute table, and route plan table. Id. at 7:47–59, FIG. 2B (reproduced
below).
Using the accessed tables, the call control engine determines a call type and an
appropriate route for the call. The call control engine locates the calling address in
a calling address attribute table, and then “screens” the called address by
comparing and analyzing the called address number to components from the
calling address attribute table. Id. at 9:15–67, FIG. 4B (reproduced below),
EX1002 ¶ 49.
To screen the called address number, the
call control engine determines a call type based
on comparing the called address to a “called
IPR2016-01082Patent 8,542,815

digits analysis table,” and attributes in the attributes tables. EX1004 at 9:41–53,
FIG. 4B (right), 5A (portion reproduced below), EX1002 ¶ 50.
Based on the determined call type and analysis of attributes, the call control
engine determines services available to the caller, and selects an appropriate route,
such as routing a call from an IP network caller to a PSTN callee. EX1004 at 7:28–
41, 9:53–67. Based on the selected route, the call routing and signaling system
generates and sends instructions for routing the call through a media gateway to the
PSTN. Id. at 6:62–7:10, 7:22–27, 8:42–48, 10:58–66, FIG. 4A (below), EX1002
¶ 51.

In particular, Turner discloses a call agent that receives a called address
from an IP gateway associated with a caller, after the caller dials a number of a
callee. Id. at 9:13-22. Similar to Kaczmarczyk, Turner discloses
reformatting/translating the addresses of the caller, and then accessing a profile
having information about the caller. Id. at 9:22–30, 22:9–15, FIG. 6, elements 602–
606, FIG. 3, EX1002 ¶ 54.
After retrieving the caller’s profile, the call
agent of Turner determines whether the called party is
within the same gateway as the caller. EX1003 at
9:24–36. That is, based on the analysis of the NA and/or CA of the caller and the
callee, as well as stored information associated with the NA and CA, the call agent
of Turner determines whether the callee is within the same gateway as the caller
and can be processed internally, such as a private network call. The call agent also
determines whether the call is directed toward a callee on another gateway, such as
a public network call. EX1003 at 9:30–36, FIG. 4A (portion reproduced to the
right). Therefore, the call agent classifies the call as a private network call or a
public network call. EX1002 ¶ 55.
If the call can be processed internally and thus is classified as a private
network call in the Turner system, the call agent sends setup instructions to the
gateway, EX1004 at FIG. 4B step 186, by composing a local IP address where the
