These maps show the proportion of patent inventors in each state since 2006.
Each inventor location is given fractional ‘ownership’ of a patent.
For example, if a patent has one New York-based inventor, one Kentucky-based inventor, and two California-based inventors, then California receives .5 credit for the patent, and the New York and Kentucky receive .25 credit each.
