* An independent inventor is an inventor whose patent, at
the time of grant, has ownership that is unassigned or assigned to an individual. The counts represent the number of times inventors are named on unassigned patents or on patents assigned to individuals. If a patent has more than one inventor, each inventor is counted. If an inventor has more than one patent, he or she is counted once for each patent. The following types of patents are counted here: utility, design, plant, and reissue patents, defensive publications, and statutory invention registrations.
