The patents dataset covers patent filings grouped into families (the same invention filed across jurisdictions). Results include inventors, assignees, classifications, filing status, publication references, and legal events, plus family size and forward citation counts for gauging a patent’s footprint. Use it to track competitor filings, map the IP landscape around a technology, or connect published research to the patents that cite it.
Requires the evidence:patents:api scope. See the Evidence overview for how scopes work.

​
Search patents

Each item in results is a patent family: { familyId, familySize, forwardCitationCount, patents, patentsTotal }, where patents holds the individual filings with title, abstract, filingStatus, classifications, inventors, assignees, applicants, appRef (application reference and filing date), publications, languages, and legalEvents.

​
Useful filters

Filter by filing or publication date with range suffixes: f=patents.appRef.filingDategte:"2022-01-01". Call GET /api_partner/evidence/patents/schema for the full filterable field list.

​
Sorting

s accepts _relevance (default), forwardCitationCount, familySize, patents.publications.pubRef.date, and patents.appRef.filingDate. Combine with sortDir=asc|desc.

​
Single patent

GET /api_partner/evidence/patents/{patent_id} returns the full record for one filing, including familySize and forwardCitationCount alongside the complete patent object.

Common uses

  • Competitive intelligence: filter by patents.assignees.name and sort by filing date to watch a competitor’s pipeline.
  • Technology landscaping: free-text query for a technique, facet by year or assignee via the facets endpoint to see who is filing and when.
  • Research-to-IP linkage: search a topic in both Search and patents to see how a body of literature translates into filings.
