- The number of patents issued rose sharply between 1995 and 1999, from 64,500
- In 1999, the state average for this indicator was 26.7 patents per 1,000
individuals in an S&E occupation, compared with 20.3 in 1995.
- The District of Columbia and Idaho were outliers, at 1.2 and 81.5, respectively,
the latter reflecting the presence of a high-patenting Department of Energy
National Laboratory in this sparsely populated state.
- The remaining states' values ranged widely on this indicator, from 8.3
to 38.3 patents per 1,000 individuals.
This indicator shows state patent activity normalized to the size of its science
and engineering workforce, specifically employees in S&E occupations. People
in S&E occupations include computer, mathematical, life, physical, and social
scientists; engineers; and post-secondary teachers in any of these fields. Managers,
elementary and secondary school teachers, and medical personnel are excluded.
The U.S. Patent and Trademark Office classifies patents based on the residence
of the first-named inventor. Only U.S.-origin patents are included.
Because of the different methods of assigning geographic location to the two
indicator measures, this indicator is of limited applicability for sparsely
populated states or for locations where a large percentage of the population
lives in one state or region and works in another.
