uspto_assignees_search
Which companies are new to patenting, and in what technology? Search patent assignee ORGANIZATIONS (entity-resolved), each with first/last grant date, patent count, distinct CPC subclasses, and inventor count. new_assignee=true isolates orgs with their first-ever US patent grant (emerging/stealth signal for VC deal sourcing and corp-dev); narrow by CPC subclass, state/country, first-grant window, or patent_count_min. PatentsView grants (CC BY 4.0), observational. [price: $0.05/row]

|---|---|---|---|
| sort | No | field:direction — patent_count | first_grant_date | last_grant_date. Default 'last_grant_date:desc'. | |
| limit | No | Max rows (default 25, cap 100). | |
| state | No | Assignee state code(s), CSV. | |

| patent_count_min | No | Minimum granted-patent count held by the org (lifetime total). | |
| pct_increase_min | No | Minimum percent increase, recent window vs prior window (100 = the count doubled) — the real patent-surge threshold. | |
