Summary
United States Patent and Trademark Office
government legacy
USPTO is the United States Patent and Trademark Office, the federal agency within the Department of Commerce that examines patent applications and registers trademarks.
What it's used for
- The agency's own network: examiner workstations and internal systems at its Alexandria, Virginia campus and regional offices, plus the public-facing patent and trademark search, filing and full-text databases.
Notable
- A government network, so the addresses are staff and agency infrastructure rather than consumers or hosting customers.
- ARIN registered this ASN to the USPTO in 1995, a genuine mid-90s allocation from the era when federal agencies were first bringing their own networks onto the commercial internet.
Interesting
- The USPTO's public search systems are among the most heavily scraped government databases anywhere, since patent and trademark records are prior art that the whole world needs to read.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,779 prefixes, as published 2026-10-22. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
