US patent applications and grants by applicant, patent/application number, inventor name, CPC class, grant-date range, or filing-date range. Filter by technology_area or is_in_force to surface live patents in a given area, by assignee_org for current ownership (full-text word/prefix match against the assignment chain-of-title), or by min_forward_citations for well-cited prior art. Coverage is patent applications and grants only — trademarks are not in this tool's schema despite the name.

Live-verified 2026-07-19: 6,330,044 records synced, 2005-01-04 through 2026-07-14. abstract/num_claims/forward_citation_count cover grants through 2025-12-31 and are null for more recent grants until the next quarterly refresh.
applicantstringApplicant/assignee name as filed, partial match
assignee_orgstringCurrent owner of record; full-text word/prefix match (e.g. "Internation" matches "International Business Machines"), not an arbitrary substring match
cpc_classstringCPC classification code, exact match, e.g. G06F16/00
is_in_forcebooleanFilter to patents currently in force (true) or not (false)
grant_date_from / grant_date_toISO dateInclusive bounds on grant_date
min_forward_citationsintegerLower bound on forward_citation_count; records with null forward_citation_count never match
limitintegerMax records to return (default 25, max 50)
Also available: patent_number, application_number (exact match), inventor (partial), filing_date_from/filing_date_to, technology_area. Unknown parameter names are rejected with an error, not silently ignored.
