Independent inventors” generally can be considered to be those inventive whose activities aren’t affiliated with an organization. Independent Inventor shows the number of "independent inventors" by state (patent origin is determined by the residence of the first-named inventor) for patents (i.e., "patents for invention") granted from 1975 to the present. Independent inventors are the inventors of those patents for which ownership was either unassigned or assigned to individuals at the time of patent grant. 

The source of the data used for these visuals is the TAF database maintained by the U.S. Patent and Trademark Office.
