Expert Witness Resume
Other Forms And Formats: PDF || Multi-Disciplinary || Academic || CV en français


I know the data communications industry from top to bottom. In over 20 years in the business I have done it all, from software coding all the way up to industry leadership and advocacy. And everything in between.

I consider myself to be: an engineer and a businessman; a tactician and a strategist; a team player and a tough manager; a software architect and a coder; a standards politician and a protocol guru; a student of the medium and a leader.

The result: an incomparable breadth of knowledge and experience spanning from the boardroom to the server room.

Expert Witness Engagements

Occasionally, I have functioned as an expert witness and a prior art locator. All my patent related work has always been on the side of defence. Here, I provide details of some of my expert witness related work. My Multi-Disciplinary Resume provides information about broader scope of my activities.

Research In Motion (RIM)
Irell & Manella
Expert Witness – Patent Infringement Defense,

In the Matter of Certain Devices for Mobile Data Communication, Docket
No. 2843 and Openwave Systems Inc. v. Apple Inc., et al., Civil Action No. 1:11-cv-00765-MSG.

In 2000, I had written two white papers:

  1. The WAP Trap
  2. WAP – The Patent Problem

warning the industry about WAP being booby trapped with patents.

The very same patents that I had mentioned were now being asserted some 12 years later.

Irell & Manella had located The WAP Trap papers and RIM hired me to assist with the case.

Assisted with prior art determination and provided various reports. Assisted with framing of subject patents as standards essential patents. Defence prevailed.

Finnegan Henderson Farabow Garrett & Dunner, L.L.P.
Expert Witness – Patent Infringement Defense ,

Assisted with prior art determination in defense of patent infringement claims and towards establishment of patents invalidity.

Expert Witness – Patent Infringement Defense,

This was a Mobile IP and wireless email related case.

U.S. Department of Justice
Technical Committee

Assisted the Technical Committee and the Department of Justice in monitoring Microsoft technical compliance with the Final Judgement. Advocated use of the model of Protocol Implementation Conformance Statement (PICS) Proforma as a verification method.

Seven Networks
Expert Witness – Patent Infringement Defense ,

Assisted Seven Networks, against patent assertions by Visto Corporation.

Subject patents were 5,968,131; 6,085,192; 6,023,708; 6,708,221.

Subject matter was mobile email synchronization.

I located physical handsets from PCSI which demonstrated prior art and invalidated various asserted claims.

Winston & Strawn
Expert Witness – Patent Infringement Defense,

Assisted with representing Nortel against a patent asserstion by Fenner Investment Ltd et al.

Subject patents were 6,819,670 and 5,561,706.

Subject matter was Mobile IP (accounting and billing).

My focus was on gathering CDPD (Cellular Digital Packet Data) relevant prior art. I located the earliest CDPD specifications. Don’t have full recollection, perhaps some aspects of a book that I co-authored: "Internetwork Mobility – The CDPD Approach" were also used in that case.

Free Protocols Foundation
Bellevue, WA
Standard Essential Patents Process Formulation,

In many of the above cases, the context of “Standard Essential Patents” were dominant.
