Patent participation, inventive links and selected pathways
The 2015–2025 Arkansas-inventor utility-grant cohort has 4,653 grants. Identified organizations occur on 4,033; these expose 755 distinct source IDs, not verified independent firms.
164 source IDs appear in at least three event years; 438 appear in only one. The five largest source IDs together occur on 1,632 unique grants. Similar names are flagged and never silently merged.
149 grants name multiple source organization IDs. 1,971 include Arkansas and another US50+DC inventor location; 370 include a foreign-country inventor. These overlapping observations identify possible inquiry routes, not operating partnerships.
295 grants carry an extracted government-interest statement; 285 carry a parsed contract number. An absent extracted statement remains unobserved, not proof of no public support.
The annual first-observed series is left-censored at 2015 and subject to patent publication/grant lags. It cannot establish firm entry. Geography is event-linked inventor location, not current residence, employment, institutional access or value capture.
Cohort records remain the PatentsView grant extract through December 2025. The selected application/assignment/event histories were retrieved on 28 October 2026; later 2026 recorded events are selected-case updates, not new cohort grants. Recorded and execution dates remain separate in the evidence tables.

Report treatment
- Describe a concentrated inventive record and measured breadth separately; source organization IDs are not verified independent firms.
- Use recurring source-ID activity to describe observed participation, without calling first appearances firm births or ecosystem entrants.
- Use joint assignees/interstate co-invention as routes for further inquiry; actual access and operating collaboration require partner evidence.
- Government-interest statements add a documented research-support connection, while assignment records sharpen access/rights questions rather than demonstrating commercial success.
