My experience with intellectual-property disputes includes providing and defending expert evidence at trial, technical patent analysis, and participation as a party in an inventorship dispute involving technology within my own field of research.
Technical expert witness
Hershkovitz, Paradox Security Systems Ltd. and Pinhas Shpater v. Tyco Safety Products Canada Ltd.
2009 FC 256 · Federal Court of Canada
Court File No. T-426-04
I served as a technical expert witness in patent litigation concerning electronic circuitry for security and alarm systems. The proceeding involved infringement and validity issues relating to telephone-line coupler circuitry used in alarm panels, and proceeded to a multi-week trial before the Federal Court of Canada in Montréal.
I appeared and testified at trial, including examination and cross-examination on the technical issues and opinions addressed in my expert evidence. This engagement involved preparing and presenting technical expert evidence, explaining electronic-circuit concepts in a litigation setting, and defending that evidence under cross-examination.
Technical consultant
California Institute of Technology v. Canon et al.
U.S. District Court for the Central District of California
Case No. CV 08-8637 VBF (VBKx)
I served as a technical consultant in patent litigation brought by the California Institute of Technology concerning CMOS active-pixel image-sensor and single-chip camera technologies. The proceeding involved eleven U.S. patents and accused products from major international camera and electronics manufacturers, including Canon, Nikon, Olympus, Panasonic, Sony, and Samsung.
I provided technical and patent-analysis expertise concerning CMOS image sensors and associated integrated-circuit architectures. The technologies at issue included active-pixel sensors, intra-pixel charge transfer, double-sampling techniques, electronic shuttering, multiresolution sensor readout, and integrated single-chip camera architectures. The engagement involved analysis of patented electronic and semiconductor technologies in a substantial multi-defendant U.S. patent-infringement proceeding.
Party to an inventorship dispute
Sirific Wireless Corporation v. Leonard MacEachern
Ontario Superior Court of Justice
Court File No. 01-CV-221390CM 3
I was a party to an inventorship dispute concerning virtual-local-oscillator technology for wireless communications. The litigation involved RF and integrated-circuit technology and questions of inventorship associated with virtual-local-oscillator techniques.
I am a named inventor on patents and patent applications concerning RF conversion and local-oscillator technologies, including Canadian Patent CA 2,281,236, Direct Conversion RF Schemes Using a Virtually Generated Local Oscillator. The proceeding is also identified as an inventorship case in the published professional history of counsel for Sirific Wireless Corporation.
Technical expert and patent analysis
Oracle Telecomputing Inc. / NAV CANADA
Air-traffic-control radar technology
I carried out technical expert and patent-analysis work concerning intellectual-property issues associated with radar and air-traffic-control technology. The engagement involved technical analysis of radar-related technology in the context of an intellectual-property dispute involving NAV CANADA.
Oracle Telecomputing Inc., based in Carleton Place, Ontario, developed mission-critical aviation systems, including air-traffic-control radar-data processing and display systems.
