Technology Footprinting and Solid-State Lighting

Jeff Tsao and Kevin Boyack · Sandia National Laboratories

Mark Huey and Ann Miksovic · Strategic Perspectives

  • Break the technology apart into sub-technology areas

  • Develop a lexical signature for these sub-technology areas

  • Identify the footprints of those signatures in a technology activity dataset (e.g., patents)

  • Compare the footprints with a desired footprint

Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin Company, for the United States Department of Energy’s National Nuclear Security Administration under Contract DE-AC04-94AL85000.
