Patent Litigation Support

  • Consult on the technical aspects of claim construction.
  • Analyze products, software, hardware, documentation, and other evidence and provide objective technical opinions concerning infringement or non-infringement of a patent.
  • Analyze prior art and provide objective technical opinions concerning validity or invalidity of a patent.
  • Produce expert reports and declarations.
  • Consult on prior art searches, assessment of prior art, and validity contentions.
  • Provide expert testimony at depositions, hearings, and trials.

I have written expert reports and declarations, provided expert witness statements, and testified as an expert witness in patent infringement cases and Inter Partes Reviews. I have testified at depositions and before judges and juries at district court trials and ITC hearings. I have also testified at a Markman hearing and a hearing regarding a dispute over a final injunction. I have consulted on claim construction, infringement and validity contentions, pre-filing investigations, and injunction disputes. And I have served as an independent technical advisor to the Court in a patent case.

Technical Expertise

I have developed electronic devices for a variety of applications: servo systems, signal detectors, and test systems for magnetic disk, CD, DVD, Magneto-Optical (MO), and WORM optical disc technologies, including the development of electronic hardware, software, firmware, analog circuits, digital circuits, microcontroller-based products, computer peripheral electronics, servo controls, sensors, and test instruments. The table below highlights many of the skills and areas of expertise that were applied in these projects.
