Submit search queries against public patent portals to retrieve result listings by keyword, IPC class, or assignee.
Extract patent metadata
Pull patent number, title, abstract, claims, inventors, assignee, filing date, and citation references.
Build IP intelligence datasets
Aggregate data to map competitive patent landscapes, identify technology clusters, and track assignee filings.

Frequently Asked Questions
Which patent databases can I extract data from?
Public patent databases including Google Patents, USPTO Patent Full-Text Database, EPO Espacenet, and WIPO PatentScope are accessible. All provide public search interfaces and full patent text for granted patents.
Can I extract full claim text from patents?
Yes. Patent pages display full claims, abstract, description, and drawings. Use structured extraction to pull independent and dependent claims as separate fields for legal and technical analysis.
