Patent Assignee Lookup
When a company is granted a US patent, the grant names the assignee — the organization that owns it. A first-ever grant marks a company that just showed up on the patent map. This searches assignees by name.

The signal
What a patent assignee tells you
A patent assignee lookup answers who owns the patents. When the USPTO grants a patent, the grant names the assignee — the organization that holds it. This tool rolls those grants up by organization: search a company name and see how many US patents it holds, the technology areas it patents in, and when it last received a grant.
Assignee data is a read on where a company invests. The count is the depth of its patent portfolio; the CPC technology areas are the fields it's building in; the grant dates trace its activity over time. Behind the unlock you get the first-grant date, the number of distinct technology areas, the count of named inventors, and whether the organization is a first-time assignee.
The signal is the first grant. An organization's first-ever US patent grant marks a company that just crossed a threshold — often an emerging or previously quiet company putting its R&D on the public record. For investors and corporate development sourcing the next name, that first appearance is exactly the moment worth catching.
Why it matters
A first-ever patent grant is an emerging-company tell before most other signals fire — a read on real R&D and a timed sourcing moment for VC deal flow, corporate development, and competitive research.
Field guide
How to read the results
Every field below is returned free, in full — no email, no gate. Build a Parse when you want the whole list for a specialty or state, exports, or a live alert the moment a prescriber goes new-to-class.
- Assignee
- The organization that owns the granted patents, as named on the grants — the company behind the portfolio.
- Patents
- How many US patents the organization holds in the corpus — the depth of its portfolio and the first read on its patent activity.
- State
- The assignee's location of record — useful for filtering to a region or market.
- Tech areas (CPC)
- The Cooperative Patent Classification subclasses the organization patents in — the fields it's actually building in (e.g. G06N for AI/ML).
- Latest / first grant
- When the organization last received a grant and when it received its first — the span that separates an established filer from a new one.
- Inventors & first-time flag
- How many named inventors are behind the portfolio, and whether this is a first-time assignee — the emerging-company signal.
Who uses it

Track new assignees in a technology area to find acquisition and partnership targets early.
Competitive & IP research
Benchmark a company or a field by patent count, technology areas, and grant activity over time.
Recruiting & talent mapping
Named inventors and patent activity map where technical talent and investment are concentrating.

FAQ
Frequently asked questions
What is a patent assignee?
The assignee is the organization that owns a granted patent, as named on the grant. A patent assignee lookup rolls a company's granted patents up by organization so you can see its portfolio, technology areas, and grant activity from a name search.
Is the patent assignee search free?
Yes. Search any company by name with no login and see its patent count, state, technology areas, and latest grant. The first-grant date, distinct technology-area count, inventor count, and first-time-assignee flag are shown free — no email or login.
What are CPC technology areas?
CPC (Cooperative Patent Classification) is the system that classifies what a patent covers. The subclasses an organization patents in tell you the fields it's building in — for example G06N for artificial intelligence and machine learning.
Why does a first-ever grant matter?
An organization's first US patent grant marks a company that just put its R&D on the public record — often an emerging or previously quiet company. That first appearance is an early sourcing signal for investors and corporate development.
How current is the patent data?
It reads the PatentsView granted-patent corpus (CC BY 4.0) that ParseData refreshes, so new grants and new assignees appear as the data updates. These are granted patents, not applications.
How it's sourced
Reads the USPTO/PatentsView granted-patent corpus (CC BY 4.0). Assignee and grant fields only — observational, never a legal determination of patent scope, validity, or ownership.
