Expert Witness and Consultant (1999 - present)

In 1999 I took my first case as an expert witness. Since that time I have worked on dozens of cases, including patent and trade secret litigation, as well as contractual disputes, and spanning a wide range of technologies such as video games, medical equipment, automotive technologies and cellular telephones. Since 2009 I have been working full-time in this capacity. I have been involved in analysis and report writing with respect to both validity and infringement, have been deposed in twelve matters (for a total of more than 20 depositions), and have testified at trial in three cases. In one particularly large case (over 1200 accused instrumentalities) I worked closely with six other experts. My role in this case evolved such that I was serving as a liaison between the attorneys and the other experts, helping each group to understand the constraints and requirements of the other. I have developed a particular expertise with respect to source code analysis of software and hardware. I have more than 10 years experience in source code analysis for wireless communications, including WiMAX, CDMA, WCDMA and LTE, with extensive experience analyzing Qualcomm modem code.

My expertise in source code analysis is largely independent of the technologies involved. The skills and experience necessary to analyse code are essentially the same, whether the code is part of a video game, a piece of  medical equipment, or a cellular phone. This fact, combined with my ability to understand complex systems quickly, has enabled me to work on cases involving source code from a broad range of technological areas. The following is a partial list of the areas in which I have worked:

  • Video Games
  • 3D Graphics
  • Virtual Instrumentation
  • Visual Programming
  • Medical Imaging Systems
  • User Interfaces
  • Spreadsheets
  • Image Processing
  • Cellular Data Communications including CDMA, WCDMA, GSM and LTE
  • ADSL Modems
  • WiMAX Networking
  • WiFi Networking
  • Panorama Stitching
  • Information Processing Automation
  • Mobile Operating Systems
  • Virtual Environments
  • Software as a Service Delivery
  • Open Source Licensing
  • Supplemental Restrain Systems
  • Blind Spot Monitoring
  • Hybrid Engine Control
  • Graphics Processing Units
  • Digital Cameras
  • Digital Rights Management (DRM)
  • Medical Information Processing
  • Online Shopping & dating
  • Flash Memory
  • Pop-up Advertising
