Search the 13,862-patent corpus
By patent number, title keyword, or assignee. Results come straight from patents.db — most will be plain records, not one of our curated pages.
What's in the corpus
The index behind this box is 13,862 US patents currently classified under CPC G06Q 40/04 (securities and commodities trading, exchanges) or G06Q 40/06 (portfolio and investment management). It's built from USPTO Open Data Portal bulk datasets — granted-patent core data, current CPC classifications, disambiguated assignees, and maintenance-fee events — at the 2026-07-04 vintage. Payment patents (G06Q 20/*) and insurance patents (G06Q 40/08) are deliberately excluded, so this is a focused slice of financial-market machinery rather than all of fintech.
How to search
- By patent number — type it with or without the US prefix and kind code: US8301675, 8301675, and 8301675B2 all resolve to the same record.
- By title keyword — a phrase like trading order or matching engine matches against patent titles.
- By assignee — a company name like BGC Partners or Chicago Mercantile pulls that owner's patents in the corpus.
What the results mean
Each row shows the patent number, title, assignee, a computed status (active, lapsed for fees, or expired by term), and an estimated term-expiry date. Those values are computed from public filing data, not looked up in a legal register — most results are plain database records served on a noindex page, because we curate roughly thirty deep pages rather than templating all 13,862. The status and dates are estimates; see the methodology for exactly how they're derived and where they can be wrong.
Frequently asked questions
What can I search here?
The full corpus of 13,862 US trading patents (CPC classes G06Q 40/04 and 40/06) by patent number, title keyword, or assignee. Most results are plain database records rather than one of our curated pages.
Where does the data come from?
USPTO Open Data Portal bulk datasets — granted-patent data, CPC classifications, assignees, and maintenance-fee events. See the methodology page for specifics and caveats.
Are the statuses and dates legal advice?
No. Status and expiry values are computed from public filing data and can differ from a patent's real legal status. Confirm against USPTO records before relying on them.
