`
`I have attached a current copy of my curricuium Vitae as Exhibit 1. A list of the
`
`cases during at least the last five years in which i have signed a Protective Order, have testified
`
`as an expert either at a trial, hearing, err-deposition, or have submitted statementsfopinions is

`
`1 attended Michigan State University from 1977 to 1981 as a Merit Schoiar and an
`
`Alumni Distinguished Scholar, and received a bachelor’s degree in Chemistry.
`
`I later attended
`
`Carnegie Mellon University from 1988 to 1995, during which time i received both a master’s
`
`HIGHLY CONFIDENTIAL — ATTORNEY EYES ONLY
`
`1 _
`
`

`

`
`
`degree (1992) and a PhD. (1996) in Computer Science. My dissertation was entitled “Safe and
`
`Efficient Persistent Heaps” and focused on high performance automatic storage management for
`
`advanced database systems.
`
`7.
`
`Before earning my Ph.D., i worked for ever four years in industry at Siiicon
`
`Solutions, Inc. and Digital Equipment Corporation, developing computer aided design (CAD)
`
`so fiware for the semiconductor and computer sectors. For example, I designed and implemented
`
`systems fer VLSI mask generation and VLSi design. ruie checking.
`
`I also built the first graphical
`
`drawing editor for the X window system, Artemis, which included a sophisticated graphical user
`
`interface.
`
`8.
`
`I have worked as a professor at three universities since 1995; the University of
`
`Pennsylvania, the University of Arizona, and The University of Texas at Austin.
`
`I was the
`
`recipient of a National Science Foundation CAREER award for “CAREER: Advancing
`
`Experimental Computer Science in Storage Management and Education” while I was an
`
`Assistant Professor at the University of Pennsylvania. During this time, I also was part of the
`
`DARPA funded SwitchWare project, which was one of the pioneering groups in the area of
`
`Active Networking (“AN”). My group developed PLAN, the first domain~specific programming
`
`language for programmable packets, as well as PLANet, the first purely active inter-network.
`
`9.
`
`I foined the faculty of The University of Texas at Austin (“UT”),
`
`in the
`
`Department of Electrical. and Computer Engineering in 1999.
`
`In 2005,
`
`I was appointed
`
`Associate Professor. with tenure. At UT, my graduate teaching has focused on networking,
`
`inciuding numerous advanced seminars on mobile and wireiess networking. My undergraduate
`
`teaching has included networking, operating systems, and one of UT’s required programming
`
`class, which focuses on programming with abstractions, Java, and data structures.

`
`At UT, 1 continued to develop AN technology and in 2002, my PhD. student,
`
`Mike Hicks, won the ACM SIGPLAN dissertation award for our joint work on software
`
`updating. Along with my PhD. student, Seong—kyu Song, I focused my AN work on mobile and
`
`wireless networking. As a result, my research shifted away from AN to mobile and wireless
`
`networking in general, especially interactions between the network, the radios, and the physical
`
`world.
`
`11.
`
`Most of my current research involves the development of Hydra, which is a
`
`working prototype of an advanced software—implemented WiFi network funded primarily by
`
`NSF. The Hydra testbed implements all of the key 802.11N technologies, including MIMO and
`
`frame aggregation (with block acknowledgements). This is documented in. my CV and as a
`
`result, I have significant direct experience with the technologies embodied in the patents.
`
`II. REVIEW AND USE OF DOCUMENTS

`
`in forming the Opinions presented in this report, I have reviewed and relied upon
`
`among other things:

`Unless otherwise noted, the deposition transcripts that I relied upon are final, and
`
`I have also reviewed the exhibits thereto.
`
`in the case that the transcripts are “roughs” or if the
`
`exhibits are not yet available, I reserved the right to review the final version and/or exhibits as
`
`they become available. The documents I have reviewed and considered for this report are given

`in Exhibit 2.
`
`III. LEVEL OF ORDINARY SKILL
`
`14.
`
`I hereby incorporate my discussion of the level of ordinary skill in the art from
`
`my initial infringement report.
`
`I note that Dr- Gibson and 1 are in general agreement as to the
`
`level of ordinary skill in the art. However, Dr. Heegard has proposed a higher level of skill in
`
`the art. Nonetheless, even under Dr. Heegard’s interpretation of the level of ordinary skill in the
`
`an, my conclusions remain unchanged.
`
`IV.
`
`SUMMARY OF OPINION
`
`15.
`
`As explained in detail in my report, in my opinion the asserted claims of the
`
`Patents—in—Snit (collectively, “the asserted ciaims”) are valid. The claims meet the requirements
`
`of35 U.S.C. § 102 and 103.

`
`
`V. CLAIM CONSTRUCTION
`
`i6.
`
`I have been informed that proper infringement analysis begins with determination
`
`or construction of the meaning of terms in the AsSerted Claims.
`
`I understand that the claims are
`
`to be construed based upon their ordinary meaning as unders'tOod by one of ordinary skill in the
`
`art,- The following chart contains the claim construction for all asserted claims, including those
`
`terms construed by the Court and those to which the parties agreed to the construction of.
`
`l have
`
`applied these constructions throughout my analysis of any and all claim limitations, both in the
`
`body of this report and in all attached exhibits and charts.
`

`
`The table below presents the claim terms currently before the court and Ericsson’s
`
`proposed constructions:

`

`18.
`
`I have applied Ericsson's proposed claim constructions for the purposes of my
`
`analysis. However, my conclusions as to invalidity will be unchanged if the Court adopts
`
`Defendants‘ proposed claim constructions, as noted throughout this report.
`
`19.
`
`The table below presents the construction of the terms or phrase agreed by the
`
`parties.
`
`’223 patent
`
`The claim term is a means-plus-
`function limitation under 35 U-S.C. §
`112, 1] 6.
`
`means for transmitting a ‘move
`receiving window” request when said
`discard timer expires and said
`acknowledgement message for each
`said at least one protocol data unit has Recited Function:
`not been received
`transmitting a ‘move receiving

`window’ request when said discard
`timer expires and said
`acknowledgement message for each
`said at least one protocol. data unit
`has-not been received
`
`
`
`Corresponding Structure:
`the transmitter, as described in 3:65-
`67 and illustrated in Fig. 2 and
`euivalents thereof
`
`VI. USE OF DEMONSTRATIVES

`
`I reserve the right to make demonstratives (including product demonstrations,
`
`product usage, and videos thereof), charts, graphs, or other similar visual aids for trial based
