`Declaration of Tal Lavian, Ph.D., in Support of
`Petition for Inter Partes Review of
`U.S. Patent No. 7,535,890
`
`I, Tal Lavian, Ph.D., declare as follows:
`
`I.
`
`INTRODUCTION AND QUALIFICATIONS
`A. Qualifications and Experience
`1.
`I have more than 25 years of experience in the networking,
`
`telecommunications, Internet, and software fields. I received a Ph.D. in Computer
`
`Science, specializing in networking and communications, from the University of
`
`California at Berkeley in 2006 and obtained a Master’s of Science (“M.Sc.”) degree
`
`in Electrical Engineering from Tel Aviv University, Israel, in 1996. In 1987, I
`
`obtained a Bachelor of Science (“B.Sc.”) in Mathematics and Computer Science,
`
`also from Tel Aviv University.
`
`2.
`
`I am employed by the University of California at Berkeley and was
`
`appointed as a lecturer and Industry Fellow in the Center of Entrepreneurship and
`
`Technology (“CET”) as part of UC Berkeley College of Engineering. I have been
`
`with the University of California at Berkeley since 2000 where I served as Berkeley
`
`Industry Fellow, Lecturer, Visiting Scientist, Ph.D. Candidate, and Nortel’s Scientist
`
`Liaison. I have taught several classes on wireless devices and smartphones. Some
`
`positions and projects were held concurrently, while others were held sequentially.

`
`communications, and computer networking technologies. For eleven years from
`
`1996 to 2007, I worked for Bay Networks and Nortel Networks. Bay Networks was
`
`in the business of making and selling computer network hardware and software.
`
`Nortel Networks acquired Bay Networks in 1998, and I continued to work at Nortel
`
`after the acquisition. Throughout my tenure at Bay and Nortel, I held positions
`
`including Principal Scientist, Principal Architect, Principal Engineer, Senior
`
`Software Engineer, and led the development and research involving a number of
`
`networking technologies. I led the efforts of Java technologies at Bay Networks and
`
`Nortel Networks. In addition, during 1999-2001, I served as the President of the
`
`Silicon Valley Java User Group with over 800 active members from many
`
`companies in the Silicon Valley.
`
`4.
`
`Prior to that, from 1994 to 1995, I worked as a software engineer and
`
`team leader for Aptel Communications, designing and developing wireless
`
`technologies, mobile wireless devices and network software products.
`
`5.
`
`From 1990 to 1993, I worked as a software engineer and team leader at
`
`Scitex Ltd., where I developed system and network communications tools (mostly
`
`in C and C++).
`
`6.
`
`I have extensive experience in communications technologies including
`
`wireless technologies, routing and switching architectures and protocols, including

`Declaration of Tal Lavian, Ph.D., in Support of
`Petition for Inter Partes Review of
`U.S. Patent No. 7,535,890
`
`Multi-Protocol Label Switching Networks, Layer 2 and Layer 3 Virtual Private
`
`Networks, and Pseudowire technologies. Much of my work for Nortel Networks
`
`(mentioned above) involved the research and development of these technologies.
`
`For example, I wrote software for Bay Networks and Nortel Networks switches and
`
`routers, developed network technologies for the Accelar 8600 family of switches
`
`and routers, the OPTera 3500 SONET switches, the OPTera 5000 DWDM family,
`
`and the Alteon L4-7 switching product family. I wrote software for Java-based
`
`device management, including a software interface for device management and
`
`network management in the Accelar routing switch family’s network management
`
`system. I have also worked on enterprise Wi-Fi solutions, wireless mobility
`
`management, and wireless infrastructure.
`
`7.
`
`I am named as a co-inventor on more than 100 issued patents and I co-
`
`authored more than 25 scientific publications, journal articles, and peer-reviewed
`
`papers. Furthermore, I am a member of a number of professional affiliations,
`
`including the Association of Computing Machinery (“ACM”) and the Institute of
`
`Electrical and Electronics Engineers (“IEEE”) (senior member). I am also certified
`
`under the IEEE WCET (Wireless Communications Engineering Technologies)
`
`Program, which was specifically designed by the IEEE Communications Society

`
`(ComSoc) to address the worldwide wireless industry’s growing and ever-evolving
`
`need for qualified communications professionals.
`
`8.
`
`From 2007 to the present, I have served as a Principal Scientist at my
`
`company TelecommNet Consulting Inc., where I develop network communication
`
`technologies and provide research and consulting in advanced technologies, mainly
`
`in computer networking and Internet technologies. In addition, I have served as a
`
`Co-Founder and Chief Technology Officer (“CTO”) of VisuMenu, Inc. from 2010
`
`to the present, where I design and develop architecture of visual IVR technologies
`
`for smartphones and wireless mobile devices in the area of network communications.
`
`9.
`
`I have worked on wireless and cellular systems using a variety of
`
`modulation technologies including time-division multiple-access (“TDMA”), code-
`
`division multiple-access
`
`(“CDMA”),
`
`and orthogonal
`
`frequency-division
`
`multiplexing (“OFDM”). Additionally, I have worked on various projects involving
`
`the transmission and streaming of digital media content.
`
`10. The above outline of my experience with communications systems is
`
`not comprehensive of all of my experience over my years of technical experience.
`
`Additional details of my background are set forth in my curriculum vitae, attached
`
`as Exhibit A to this Declaration, which provides a more complete description of my
`
`educational background and work experience.
