A Patent Technology Monitoring Division Report
An independent inventor, also called an individual inventor, is one whose patent, at the time of grant, is unassigned or assigned to an individual (i.e., ownership of the patent is not assigned to an organization).
The counts in this report represent the number of times inventors from particular states are named on unassigned patents or on patents assigned to individuals. If the patent has more than one inventor, each inventor is counted according to his or her state of residence. 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")
granted by the U.S. Patent and Trademark Office during the period
01/01/1975 - 12/31/2003.
The source of the data used for this report is the TAF database maintained by the Office of Electronic Information Products.
