Professional Experience

2006-present President of Sourland Mountain Associates, Hillsborough, NJ
  • Technical & patent consulting in flat panel displays, semiconductors, and RFID.  
  • Extensive experience in drafting thousands of effective patent claims and conducting hundreds of detailed
    patent evaluations.  
  • Patent litigation experience includes both jury and bench trials, ITC experience, Markman hearings,
    depositions, expert reports, and testifying as an expert witness in three international patent trials.

2005-2006 VP of Engineering, Applied Wireless ID, Morgan Hill, CA
  • Responsible for patents, developing advanced reader architectures based on international standards, and
    integrating these architectures into monolithic chips.
  • Led industry-wide role in developing international standards for RFID tags & readers.  Elected as a
    Founding Member of the EPCglobal Architectural Review Committee.  

2003-2005 Founder, Chief Technology Officer, Board of Directors, Intelleflex Corporation, San Jose, CA  
  • Responsible for engineering, product development, and manufacturing of high-performance RFID tags with
    associated flexible displays.

1999 - 2002 VP of Engineering, Chief Technology Officer at Alien Technology Corporation, Morgan Hill, CA  
  • Managed three technical Directors and reported directly to the Board of Directors.  Directed IC design, IC
    foundry relationships, trademarks, licensing agreements, patents, and other legal matters.  
  • Rapidly developed five state-of-the-art mixed-signal custom IC chips for Alien's flexible displays and RFID
    products.  Assembled a world class IC development team within 6 months and rapidly completed all five
    chips - including Alien's first RFID chip - each one working with first silicon.
  • Represented Alien in the international RFID standards setting process including presentations to US
    Government, Universities, Venture Capitalist meetings, and other companies.  Led the MIT Auto ID Center's
    effort to develop a new, low-cost RFID tag specification based on Alien's design, that was subsequently
    adopted in June’01 by all three RFID international standards-setting organizations.
  • Expanded Alien's patent portfolio from only 4 patentapps in 1999 to 79 patent apps by the end of 2002.

1981-1999 Laboratory Director, Sarnoff Corporation, Princeton NJ
  • As Director of the Solid State Display Laboratory my responsibilities included funding and managing a 6 M$
    annual budget for 20-30 persons in the field of Active Matrix LCDs, Active Matrix OLEDs, and other flat
    panel display devices.  
  • Successfully negotiated numerous patent licensing and technology development contracts including several
    multi-million dollar agreements in France, Korea, and Japan.
  • Founded Sarnoff "spin-out" corporation, SARIF Corporation, Inc., with initial funding of 10 M$.  
  • Developed the first polysilicon AMLCDs in 1986; developed the world's first Active Matrix Electroluminescent
    (AMEL) displays in 1994; and developed the world's first self-scanned amorphous silicon AMLCDs (SASID)
    in 1995.

1981 Before 1981, pioneered development of semiconductor memories and non-volatile memory products.  
  • Designed and transferred into high-volume commercial production a CMOS microprocessor, two CMOS
    ROM chips, three CMOS static RAM chips, two EEPROM chips, and a 256 MHz ultra-high-speed shift
    register chip.  
  • Patents currently used in over 85% of all DRAM and RAM manufactured worldwide.  Patent 4,344,005
    "Power Gated Decoding" and Patent 4,558,240 "Multi Mode Amplifier" have generated over $100M in
    royalties for the Harris Semiconductor Corporation.

  • Received numerous awards, including the “David Sarnoff Award for Outstanding Technical Achievement” -
    the highest award offer made by either RCA or Sarnoff - for founding a new display company called “SARIF
    Inc.” in 1994.
  • Taught courses on solid state circuits and flat panel display technology for Boeing, RCA, the IEEE, the
    Society of Information Display, and the University of California.  
  • Chairman of the 1977 IEEE SOS Workshop, VLSI Workshop Committee 1984-1986, the ISSCC Committee
    from 1986-1989, Member or Chairman of the AMLCD Technical Program Sub-Committee for SID from 1989
    to the present.  
  • Founding member of the RFID Standards Working Group at MIT in 2002.  
  • Elected as a Founding Member of the EPCglobal Architectural Review Committee in 2004.
