Patent-related Experience

  • Actively involved in drafting the claims of all of the patents listed above.
  • Served as consultant to a Fortune-500 company. Over a 2 ½ - year period:
    • Planned and conducted patent portfolio searches: evaluating over 300 core technology patents;
    • Assessed viability of patents with respect to potential infringement and applicability to core technologies of company;
    • Identified potential patent infringement situations and advised re. litigation & licensing;
    • Reverse-engineered several devices and subsystems of potentially offending companies;
    • Constructed several patent claims "maps" for licensing negotiations.
  • Served as a testifying expert witness in patent infringement case against an optical imaging manufacturer. (Subsequent verdict resulted in a willful infringementjudgment against the defendant.)
  • Based on my patents issued 2003 – 05, a start-up company, Pandanus Inc., was formed to develop high performance integrated optic devices for the telecommunications market.
