A Patent Technology Monitoring Team Report


Description of the Report

An independent inventor (also called an individual inventor), for purposes of this report, is a person whose patent, at the time of grant, has ownership that is unassigned or assigned to an individual (i.e., ownership of the patent is not assigned to an organization).

The counts in this table represent the number of times inventors from particular states are named on unassigned patents or on patents assigned to individuals. If a patent has more than one inventor, each inventor is counted according to his or her state of residence at the time of patent grant. If an inventor has more than one patent, he or she is counted once for each patent.

This report counts the number of times inventors from particular states are named on documents of the following type(s):
utility patents (i.e., 'patents for invention'), design patents, plant patents, reissue patents, statutory invention registrations, defensive publications
granted by the U.S. Patent and Trademark Office during the period JANUARY 1977 -- DECEMBER 2015. Counts of inventors and their patent grants are broken out by calendar year.

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