`
`I.
`
`INTRODUCTION
`1.
`
`I have been retained as a technical expert on behalf of petitioner
`
`AT&T Services, Inc. in connection with the above-captioned inter partes review
`
`(“IPR”) of U.S. Patent No. 8,542,815 (“the ’815 Patent”). I understand that the
`
`’815 Patent is currently assigned to Digifonica (International) Limited.
`
`2.
`
`I am familiar with the technology at issue in the period prior to
`
`November 2, 2006, which is the filing date of the provisional application to which
`
`the ’815 Patent claims priority. I have not performed an analysis to determine
`
`whether any of the claims of the ’815 Patent should be entitled to this earlier
`
`priority date. However, none of the opinions stated herein would change if any
`
`claim were entitled to this earlier priority date.
`
`3.
`
`I have been asked to provide my technical opinion on concepts
`
`discussed in the ’815 Patent and the reference documents, as well as my technical
`
`opinion on how these concepts relate to several ’815 Patent claim limitations in the
`
`context of the specification.
`
`4.
`
`I have been asked to consider how a person of ordinary skill in the art
`
`would understand the claims of the ’815 Patent and the applied reference
`
`
`

`
`combinations. In reaching the opinions stated herein, I have considered the ’815
`
`Patent and the references discussed herein in the context of my own education,
`
`training, research, knowledge, and personal and professional experience.
`
`5.
`
`I am being compensated at my standard hourly rate of $350.00 per
`
`hour. My compensation is not dependent on the outcome of this IPR and in no
`
`way affects the substance of my statements in this declaration.
`
`6.

`I make this declaration based upon my own personal knowledge and,
`
`if called upon to testify, would testify competently to the matters contained herein.
`
`I may rely on handbooks, textbooks, technical literature, my own personal
`
`experience in the field, and other relevant materials and/or information to
`
`demonstrate the state of the art in the relevant period and the evolution of relevant
`
`technologies.
`
`II.
`
`SUMMARY OF OPINIONS
`7.
`
`After studying the ’815 Patent, its file history, and the prior art, and
`
`considering the subject matter of the claims of the ’815 Patent in light of the state
`
`of
`
`technical advancement
`
`in
`
`the area of
`
`IP
`
`telephony networks and
`
`telecommunications networks prior to the filing of the ’815 Patent, I reached the
`
`conclusions discussed herein.

`

`

`Declaration of James Bress in Support of Petition for Inter Partes Review
`of U.S. Patent No. 8,542,815
`
`
`8.
`
`In light of these general conclusions, and as explained in more detail
`
`throughout this Declaration, it is therefore my opinion that Claims 1, 7, 27–28, 34,
`
`54, 72–74, 92–93, and 111 (the “Challenged Claims”) of the ʼ815 Patent are
`
`invalid as being obvious in the relevant time frame (prior to November 2006) in
`
`light of the knowledge of a person of ordinary skill in the art at that time and the
`
`teachings, suggestions, and motivations present in the prior art.
`
`III. BACKGROUND AND QUALIFICATIONS

`
`I received a Bachelor of Science degree in electrical engineering from
`
`the University of North Carolina at Charlotte in 1985, and a Master of Science
`
`degree in electrical engineering from the California Institute of Technology in
`
`1987. From 1982 to 1984, while still attending the University of North Carolina, I
`
`My duties there included technical writing for field‐located energy management
`field‐located equipment and host systems.
`
`was an engineering technician at Process Systems, Inc., located in Charlotte, NC.
`
`equipment which was remotely accessible via modems and telephone lines, host
`
`system software and user manuals, as well as developing test equipment for the
`
`11.
`
`In addition to my educational background, I have over 30 years of
`
`experience in the telecommunications industry. In 1985, after graduating from the
`
`University of North Carolina, I was employed by Bell Communications Research,
`
`Inc. (also known as Bellcore), located in Piscataway, NJ. I was an engineer and
`
`Member of the Technical Staff (MTS) at Bellcore with responsibility for numerous
`
`telecommunications systems operations and development projects. For these
`
`systems-related projects, I was responsible for development, integration, and
`
`testing including computers, network hardware, network interconnections, network
`
`signaling, network protocols, network equipment provisioning and configurations,
`
`database technologies, applications and software development, user interfaces,

`
`client-server operations, test systems development, and telephony features
`
`development and prototyping.
`
`12.
`
`In 1995, I founded AST Technology Labs, Inc., located in Melbourne,
`
`Florida, where I am the President and Chief Technical Officer. AST’s business is
`
`focused on telecommunications equipment and networks. My responsibilities at
`
`AST include the development of detailed system specifications, architectures,
`
`hardware, and software for custom telecommunications and telephony test systems
`
`including analog, digital, VoIP, and wireless. My responsibilities also include
`
`researching and analyzing the products that are tested at AST to enable system
`
`configurations, preparation for testing, troubleshooting hardware and software, and
`
`providing consulting to AST’s customers.
`
`13.
`
`I have served on numerous standards setting committees of the
`
`Telecommunications Industry Association (“TIA”) and have been a prime
`
`contributor, editor, and working group chairman for the development of many
`
`published ANSI
`
`(American National
`
`Standards
`
`Institute)
`
`/ TIA
`
`telecommunications standards. I served continuously from 2000 to 2015 as
`
`chairman or vice chairman of the TIA TR41.3 engineering subcommittee for
`
`Performance and Accessibility for Communications Products. Starting in 2015 and
`
`to the present, I am the chairman of the parent engineering committee, TR41. I

`
`also authored numerous system requirement publications and recommendations for
`
`Bellcore. Additionally, I am a named inventor on four issued US patents.
`
`14. My first assignment during my employment at Bellcore was in the
`
`software operations area. This area was focused on operations system software
`
`including PREMIS (PREMise Information System), SOAC (Service Order
`
`Analysis & Control), and LFACS (Loop Facility Assignment and Control System).
`
`These software systems integrated hardware (network access and switching
`
`equipment and computers) and software (database, reporting, network control,
`
`monitoring, management, and user interface) used for the operations systems used
`
`by Bellcore’s owners (the Regional Bell Operating Companies (RBOCs) or “Baby
`
`Bells”) in support of the Public Switched Telephone Network (PSTN). My
`
`experiences during this assignment included software installation and testing,
`
`network management, network equipment provisioning, database configuration
`
`and schema development, network connectivity troubleshooting, and software
`
`documentation.
`
`15. My next assignment at Bellcore was on a development team for the
`
`“Information Gateway” project. My responsibilities included data network design,
`
`network connectivity implementation, network equipment configurations and
`
`provisioning, and troubleshooting for the networked connectivity of computer
`
`
`

`
`AT&T, Exh. 1003, p. 12
`
`

`

`Declaration of James Bress in Support of Petition for Inter Partes Review

`
`systems located in multiple states across the USA. Networking for this project
`
`included PSTN and data network facilities and services and interworking between
`
`the PSTN and data networks. The computer systems provided access to servers,
`
`databases and terminal interface software from distributed network connected
`
`workstations. In addition to networking, I was also responsible for database
`
`system design and distributed network access to compressed image files located on
`
`a network connected server. One of my many projects included analysis,
`
`configurations, and troubleshooting of X.25 data network termination circuits, and
`
`the related termination equipment, to enable numerous system demonstrations that
`
`were set up in multiple locations across the USA.
`
`16. My work in Bellcore’s “New Services Development” area included
`
`designing and prototyping new services that were focused on the use of the
`
`Advanced Intelligent Network (AIN) system features and components. These
`
`projects required an understanding of telecommunications systems network
`
`architectures, signaling, protocols, standards, and features operations. One of my
`
`projects in this area included interfacing to AIN components including Service
`
`Control Points (SCP) and Signaling Transfer Points (STP) to implement a
`
`telephone network control feature. I am the first named inventor on a patent for
`
`
`

`
`

`
`one of the systems developed which was integrated with the AIN (U.S. Patent No.
`
`5,570,420, “Customer premise equipment network integrator”).
`
`17. Another assignment I had at Bellcore involving network signaling and
`
`features was for the development of the Analog Display Services Interface (ADSI)
`
`and the Caller ID on Call Waiting (CIDCW) feature that is now well known to
`
`telephone users. My responsibilities included analyzing PSTN switching systems
`
`architectures and capabilities, and feature related network triggers and service
`
`logic. I was also responsible for developing prototype systems, including hardware
`
`and software, for network signaling and features evaluation. Additionally, I was
`
`responsible for developing Bellcore’s Customer Premises Equipment (CPE) test
`
`lab (including hardware, software, lab operations, and reporting) to support the
`
`development of new telephony devices used with the ADSI and CIDCW features.
`
`18.
`
`I started designing network signal detection systems as a
`
`troubleshooting assignment for the Bell Companies. At this time in the late 1980s,
`
`most prison systems used primarily coin telephones, which were owned and
`
`operated by the Bell Companies, to provide telephony services to inmates. Inmates
`
`had discovered that they could defraud the telephone system by playing certain
`
`music into the telephone transmitter (microphone), which would cause the Bell
`
`Company Central Office (CO) accounting and billing systems to errantly record

`
`sometimes hundreds of dollars of credit due to falsely detecting coin-drop-
`
`confirmation tones. After this problem was solved, the knowledge I gained was
`
`used to develop Bellcore’s prototype CPE Alerting Signal (CAS) detector that was
`
`a key component of what became the widely popular Caller ID on Call Waiting
`
`(CIDCW) telephony feature. This work led to the issuing of U.S. Patent No.
`
`5,519,774 “Method and system for detecting at a selected station an alerting signal
`
`in the presence of speech” for which I am a named inventor.

`
`I am the first named inventor on U.S. Patent No. 7,076,031 “System
`
`and Method for Telephone Signal Collection and Analysis.” The impetus for this
`
`patent was the development of the TSA-6000® telephone signal recording and
`
`analysis system. This project culminated into the manufacture and sale of TSA-
`
`6000® systems starting in 2002. I was the chief architect for the design of this
`
`system and I continue to serve as the technical lead for this project and product.
`
`The TSA-6000® system was designed using the concept of functional units that
`
`can be combined in any physical implementation including the functions of 1)
`
`signal data capture and recording; 2) analysis of the captured signaling data to
`
`identify pre-defined telephone signals and events occurring in the recorded signals,
`
`as well as identifying the states, or modes of the telephone line; and 3) a user-
`
`friendly graphical interface for viewing signals and analysis data, and also for

`
`system configurations such as changing the parameters used during the analysis
`
`operations. The software of the TSA-6000® was developed using C language and
`
`runs on a Windows®-based computer. The software has been revised over the
`
`years for multiple reasons including to add new pre-defined signal types or
`
`classifications, and to modify and enhance the signal analysis algorithms.
`
`20. While employed at AST Technology Labs (AST), I have been
`
`responsible for the development of a “Call Generator” system for Telcordia
`
`Systems (formerly Bellcore). The Call Generator system included PSTN and data
`
`network interfaces integrated with a network based controller system. My
`
`development responsibilities for
`
`the controller system
`
`included hardware
`
`integration,
`
`software development
`
`including network
`
`control,
`
`remote
`
`configuration, database, and user interfaces. The system was designed to
`
`demonstrate Telcordia’s larger system goal of handling “one million calls per
`
`minute” for emergency management. The system was installed at Telcordia and
`
`used for demonstrations by Telcordia management and sales teams.
