How this service works
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.
Output
A paginated list of entity-resolved assignee organizations, each including: organization name, resolved entity ID, first grant date, last grant date, total patent count, list of distinct CPC subclasses patented in, and inventor count. Filterable by new-assignee flag, technology area, geography, and grant date window.
Example use cases
VC deal sourcing via first-time patentors
“Show me companies that received their very first US patent ever between January 2024 and December 2024 in the AI/ML space (G06N), with at least 1 patent, sorted by most patents first — I want to find stealth startups worth reaching out to.”
Corp-dev target scan in robotics
“Find emerging companies that just started patenting in robotics — filter to first-ever grants after 2023-01-01 in B25J (manipulators/robots), US-based, with no more than 10 patents total, sorted by first grant date descending.”
Regional tech landscape mapping
“Which organizations headquartered in Texas are new to patenting in clean energy technology? Look for first-ever patent grants after 2022-01-01 in the Y02 CPC section, limit to 50 results sorted by inventor count.”

Endpoint
GEThttps://api.govparse.io/v1/patents/assignees/searchWhen to prefer
Choose this endpoint when you need to identify organizations as patent holders with aggregate statistics — especially when discovering first-time patentors (new_assignee=true) for VC or corporate development signals. Prefer this over the individual-patent search endpoint when your unit of analysis is the company, not a specific patent grant. Best when you need to slice by technology area (CPC), geography, and grant date windows simultaneously.
Side effects
- Invalid CPC subclass code returns empty results or 400 error
- Unrecognized state/country codes may silently return no results
- new_assignee=true with a broad date range may return very large result sets requiring pagination
- Entity UUID mismatches return no results if the ID isn't in the resolved entities database
- Rate limiting or payment failure (x402) if USDC payment not properly handled
